Description:FIELD OF THE INVENTION

[0001] The present invention relates to a foundry sand-based concrete manufacturing device that effectively recycles waste foundry sand into concrete while allowing users to input specific requirements for customized concrete preparation based on different construction purposes.

BACKGROUND OF THE INVENTION

[0002] The need for waste foundry sand-based concrete manufacturing arises from the growing environmental concerns related to waste disposal and the depletion of natural resources. Foundry sand, a by-product of metal casting is produced in large quantities and often ends up in landfills, causing environmental hazards. Utilizing this waste material in concrete production provides a sustainable solution by reducing the demand for natural aggregates like river sand, which are increasingly scarce and contribute to ecological damage when extracted. By incorporating waste foundry sand into concrete, it not only helps divert this waste from landfills but also enhances the material properties of concrete, such as improved workability and potential durability benefits. Also, the use of foundry sand in concrete manufacturing reduce the environmental footprint of concrete production, as this lowers energy consumption and carbon emissions associated with the mining, transportation, and processing of natural aggregates. Furthermore, this approach supports a circular economy by promoting the reuse of industrial waste for contributing to more sustainable construction practices. As industries seek eco-friendly solutions, foundry sand-based concrete offers a viable option to address both waste management and the demand for building materials.

[0003] Traditional methods of incorporating waste foundry sand into concrete manufacturing involve blending the sand with cement, aggregates, and water in standard concrete mix designs. This method aims to replace a portion of natural sand with foundry sand, providing a sustainable use for waste material. While these approaches reduce the environmental impact by decreasing reliance on virgin sand and diverting waste from landfills, they also come with notable drawbacks. One of the main challenges is the variability in the quality of foundry sand, which differ depending on the type of metal cast and the additives used. This inconsistency affect the concrete's performance, including its strength, durability, and workability. Moreover, traditional methods often require extensive testing and adjustments to optimize the mix, which increase the complexity and cost of production. The presence of contaminants in foundry sand, such as oils, binders, and heavy metals also interfere with the chemical reactions in concrete that leads to reduced quality or long-term degradation of the material. The potential for leaching of harmful substances from the concrete into the environment remains a concern. Thus, while waste foundry sand-based concrete offers environmental benefits, traditional methods face challenges in achieving consistent and reliable performance.

[0004] US4130436A discloses about an invention that has a process for treating waste foundry core and/or molding sand in a manner which upgrades these scrap streams to new sand quality for entry at the core making point. The process consists of incrementally heating the sand as required up to temperatures in the 1800° to 2500° F range, followed by cooling. The degree of heating is chosen to achieve a desired lowering of acid demand value (ADV) from that which would result from heating only to conventional high temperatures, about 1500° F. Lowering of ADV reduces the variability which would otherwise be introduced into a mixture of new and recycled sand for cores. Heating waste molding sand to the temperatures contemplated by the method of this invention also causes clay additives to fuse, become non-absorptive and thus eliminating the need for mechanical attrition which would otherwise be needed to remove the clay so that it would not absorb high quantities of resin in the core making process. The inventive method also burns off resins from the sand being treated in a manner which eliminates environmental pollution.

[0005] KR100254484B1 discloses about an invention that has a recycling method of waste mould sand is provided to substitute expensive bentonite with recycled mould sand to a considerable extent. Thus, high cost used for purchasing bentonite that has been imported entirely can be saved considerably and also this method has merit at a standpoint of preventing environmental pollution. The recycling method is characterized by collecting waste mould sand; sorting it with a sorting machine; meshing sorted mould sand with a mesh sized 40; blending 70-80wt.% of recycled mould sand (containing bentonite) which is free of foreign materials and metals with 20-30wt.% of new sand.

[0006] Conventionally, many methods are available for manufacturing concrete from waste sand-foundry. However, the cited invention lacks in fully optimizing the properties of the recycled sand for high-performance concrete applications. Existing methods fail to address the fine-tuning of moisture content or particle size distribution, both of which are critical for ensuring consistent and durable concrete. The mentioned methods do not always provide efficient solutions for large-scale concrete production, particularly in terms of minimizing energy consumption, labor, or material waste. As a result, these conventional methods does not meet the growing demand for sustainable and high-quality concrete products in modern construction projects.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of efficiently recycling waste foundry sand into high-quality concrete for ensuring precise control over the sand’s properties such as particle size and moisture content to match that of regular sand. The developed device should allow for automated and customized processing of the foundry sand, where different parameters are adjusted based on the specific needs of the concrete application, whether for construction, road building, or other uses, thus offering a significant step forward in the sustainable use of industrial waste in construction.

[0022] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0023] The present invention relates to a foundry sand-based concrete manufacturing device focuses on facilitating thorough and uniform mixing of materials to produce high-quality concrete, with the flexibility to adapt the mixture for various applications, such as road construction or other infrastructure projects.

[0024] Referring to Figure 1, an isometric view of a foundry sand-based concrete manufacturing device is illustrated, comprising a housing 101 developed to be positioned on a ground surface installed with a first chamber 102, a touch interactive display panel 103 is mounted on outer surface, a first motorized mixing unit 104 installed inside the first chamber 102, multiple motorized iris holes 105 are located on bottom of the first chamber 102, sieve plate 106 is placed at bottom of the first chamber 102 via a supporting L-shaped link 107, a second chamber 108 installed underside the first chamber 102, a vibrating unit 109 attached to the sieve plate 106, a primary heating unit 110 is installed on the sieve plate 106, a multi-sectioned container 111 mounted inside the second chamber 108, a motorized iris unit 112 is integrated with each of the container 111, a second motorized mixing unit 113 installed inside the second chamber 108, an electronic valve 114 attached with the second chamber 108 and lined with a conduit 115, a curing platform 116 installed on bottom portion of the housing 101, a vessel 117 stored with water, a secondary heating unit 118 is installed with the curing platform 116, an opening 119 is carved on front wall of the housing 101 and an electronic nozzle 120 connected with said second chamber 108 via a hollow pipe 121.

[0025] The device disclosed herein includes a housing 101 that is intended to be positioned securely on a ground surface for ensuring stability and ease of use. The housing 101 serves as the main structure that is built to withstand the operational processes involved in recycling foundry sand into usable concrete. Within this housing 101, a first chamber 102 is integrated to receive and store the foundry sand, which is the key raw material for the concrete manufacturing process. This chamber 102 is specifically developed to hold a certain quantity of foundry sand for ensuring a continuous and reliable input for subsequent stages of processing.

[0026] A touch interactive display panel 103 is mounted on the outer surface of the housing 101 that serves as the interface through which the user interacts with the device. The display panel 103 is developed to be intuitive and user-friendly that allows the user to easily input specific details about how the foundry sand is to be utilized. The interactive interface enables the user to customize the device's settings depending on the intended application of the concrete mixture, such as whether the concrete is to be used for construction, roadwork, or other purposes. This customization includes adjusting parameters like sand processing, moisture levels, and the type of concrete mixture needed for a particular task. The touch interface simplifies the process of inputting these details by providing visual prompts and interactive options for ensuring that even those with minimal technical knowledge are able to operate the device effectively.

[0027] Once the user specified the desired parameters for the foundry sand processing, the microcontroller receives these commands and initiates the necessary actions to execute the process. The microcontroller is pre-fed to ensure precise control of a first motorized mixing unit 104 that is installed within the first chamber 102. This mixing unit 104 comprises of a helical spring connected with an electric motor that rotate the helical spring in both clockwise and counter-clockwise directions, allowing to effectively break down and reduce the size of the foundry sand particles. The dual-directional rotation ensures that the sand is thoroughly processed, with the motorized mixing unit 104 for ensuring that the particles are finely ground for facilitating their further use in concrete production.

[0028] The first chamber 102 where the sand is processed is equipped with multiple motorized iris holes 105 located at the bottom of the chamber 102. These iris holes 105 control the discharge of the sand after the sand is adequately mixed and reduced to the required size. The motorized iris holes 105 get open and close as needed for providing a controlled release of the sand. This allows for the precise discharge of the sand over a sieve plate 106 installed by means of a L-shaped link 107 for ensuring that only sand particles of the correct size are allowed to pass through, while larger or undesirable particles are retained. This controlled discharge ensures that the sand is prepared to the exact specifications required for the next steps in the process.

[0029] As the sand is discharged over the sieve plate 106, the sand is sifted, with finer particles passing through the sieve, while coarser particles are left behind. This ensures that only properly processed, fine-grained sand is transferred into the next stage of production. The sieve plate 106 aids in maintaining the consistency and quality of the final concrete mixture, as the particle size of the sand directly affects the properties of the concrete. Once the sand is sieved, the sand is then transferred from the first chamber 102 into a second chamber 108, which is installed beneath the first chamber 102. The second chamber 108 is developed to hold the sieved sand and is essential for the next phase of the concrete manufacturing process.

[0030] A vibrating unit 109 is attached directly to the sieve plate 106 for ensuring that the sand is evenly distributed across the sieve surface. The vibrating unit 109 is controlled and activated by the microcontroller based on the commands provided by the user. The vibrating unit 109 facilitate the consistent and uniform spreading of sand particles across the sieve plate 106 for ensuring that no areas are left under-processed or over-processed. As the motorized iris holes 105 discharge the sand over the sieve plate 106, the vibrating action works to evenly disperse the sand, preventing clumping or uneven distribution, which affect the quality of the sieving process. The even distribution of sand allows for a more thorough sifting process where finer particles pass through the sieve and coarser particles remain in view of ensuring that the sand meets the desired specifications for further use.

[0031] The vibrating unit 109 is carefully calibrated to generate the appropriate frequency and amplitude of vibrations to achieve the desired spread without disrupting the structure or integrity of the sieve plate 106. By vibrating the sieve plate 106, the device ensures that the sand is not only evenly distributed but also that the sifting process happens more efficiently as the movement helps loosen any particles that are stuck or aggregated for further enhancing the sieving process. The uniformity achieved through this vibrating unit 109 is essential for the overall quality of the concrete as the size and consistency of the sand particles directly impact the final mixture's strength, texture, and workability. The vibrating unit comprises of a motor connected with an eccentric shaft which is further mechanically assembled with the sieve plate using one or more gears.

[0032] To optimize the sand for concrete production, the device includes a primary heating unit 110 installed directly on the sieve plate 106. The primary heating unit 110 works in conjunction with the vibrating unit 109 to further refine the sand's properties. The heating unit 110 is developed to gradually raise the temperature of the sand as the sand moves across the sieve plate 106. This gentle heating process is crucial for reducing the moisture content of the sand. The microcontroller regulates the heating unit 110 based on real-time data received from a moisture sensor integrated into the sieve plate 106. The moisture sensor continuously monitors the amount of moisture present in the sand for providing feedback to the microcontroller, which adjusts the electric current supplied to one or more heating coils of the heating unit.

[0033] The moisture content of the segregated sand matches the moisture level found in regular sand used for concrete production. Foundry sand often contains higher moisture levels, which affect the mixing properties and overall performance of the concrete. If the sand retains too much moisture, this disrupt the bonding process between the cement, water, and aggregates, leading to weak or inconsistent concrete. The primary heating unit 110, in collaboration with the moisture sensor, reduces excess moisture by gradually evaporating water from the sand, bringing to an optimal moisture level suitable for concrete mixing. This precise control ensures that the sand is neither too dry nor too wet, thus maintaining consistency and quality in the concrete mixture.

[0034] A multi-sectioned container 111 is mounted inside the second chamber 108 that hold and store essential raw materials required for the production of concrete. These raw materials include cement, water, and aggregates such as sand, gravel, or crushed stone. The multi-sectioned container 111 ensures that each material is stored separately in its own designated section for preventing cross-contamination and allowing precise control over the proportions of each material that are mixed into the concrete. The sections of the container 111 are carefully sized to accommodate the required quantities of each material based on the specifications provided by the user through the touch interactive display panel 103. By organizing the materials into distinct sections, the device ensures that each raw material is dispensed independently and in the right amount as needed for the concrete mixing process.

[0035] Each of these containers 111 is equipped with a motorized iris unit 112 for dispensing controlled amounts of raw materials from the multi-sectioned containers 111. These iris unit 112 function by opening and closing based on commands from the microcontroller, which interprets the user’s input and adjusts the dispensing of each material accordingly. The motorized iris unit 112 are capable of precise control in view of allowing the exact amount of cement, water, or aggregates to be released into the second chamber 108. This level of control is crucial for ensuring the correct mix proportions, as the ratio of cement, water, and aggregates directly affects the strength, workability, and durability of the concrete. The microcontroller adjusts the operation of these iris unit 112, opening or closing the units at the appropriate times to release the desired amount of each material into the second chamber 108.

[0036] Once the materials are dispensed into the second chamber 108, a second motorized mixing unit 113 is activated to ensure thorough blending of the raw materials with the previously sieved sand that is transferred from the first chamber 102. The second motorized mixing unit 113 comprises of a second helical spring that rotate at an optimum speed to achieve consistent and uniform mixing. The speed at which the mixing unit 113 operates is carefully calibrated to ensure that the materials are thoroughly combined, but without causing excessive shear or damage to the components. The mixing facilitated by this unit ensures that the raw materials such as cement, water, aggregates, and sand are blended together into a homogeneous mixture, thus forming the concrete paste needed for construction.

[0037] The mixing process within the second chamber 108 is essential for achieving the desired consistency and workability of the concrete. This ensures that all particles are evenly coated with the cement paste that results in a uniform and stable mixture that is ready for use. The microcontroller continually monitors the mixing progress, adjusting the mixing unit’s speed and duration to ensure the proper blending of materials. This real-time control make sure that the concrete mixture maintains its desired characteristics, such as the right consistency and flow which are crucial for the final application, whether it's casting tiles, building structures, or paving roads.

[0038] The microcontroller ensures that the mixing process is fully automated and is customized based on the user's specific needs. If, for example, the user specifies a different concrete mix for road construction versus tile production, the device adapt by dispensing the correct proportions of materials. This automated dispensing and mixing process reduces the likelihood of human error and enhances the efficiency of the concrete production process, and ensures a consistent final product, all of which are important for large-scale or high-quality construction applications.

[0039] Once the concrete paste is mixed and is ready for shaping, an electronic valve 114 attached to the second chamber 108 aids in directing the paste into molds positioned on a curing platform 116. The electronic valve 114 controlled by the microcontroller is capable of regulating the flow of the paste in a precise manner. The microcontroller operates the valve 114 based on the user’s input and the required concrete application for ensuring that the correct amount of paste is dispensed over multiple molds.

[0040] The valve 114 is connected to the second chamber 108 through a conduit 115, which acts as a channel through which the paste travels to be deposited into the molds. The conduit 115 ensures that the paste is evenly distributed across the molds without clumping or spillage which is essential for creating uniformly shaped tiles or other concrete products. The smooth and controlled flow of the concrete paste over the molds is essential to ensure that each mold is filled with the correct amount of material, thus preventing underfilling or overfilling which compromise the quality and consistency of the finished product. The mold shapes the concrete into the desired form, whether it be for tiles, slabs, or other concrete products.

[0041] Once the paste is transferred into the molds, the curing process begins. The curing platform 116, which is located at the bottom portion of the housing 101, provides the surface on which the molds are placed for hardening. The curing platform 116 is equipped with a vessel 117 that contains water, which is crucial for maintaining the appropriate moisture level during the curing process. An electronic spout is connected to this vessel 117 and is regulated by the microcontroller to ensure that a consistent and controlled amount of water is released onto the molds. The water from the spout is dispensed onto the molds to keep the concrete moist during the curing process as maintaining the correct moisture content is critical for the proper hardening and development of strength in the concrete. Without adequate moisture, the concrete does not set correctly which leads to a weak or inconsistent final product.

[0042] The curing platform 116 is equipped with a secondary heating unit 118 that works in collaboration with the water spout to create the ideal curing environment. The secondary heating unit 118 is developed to gradually increase the temperature of the molds during the curing process. This gradual increase in temperature helps to accelerate the hydration of the cement particles in the concrete mixture for promoting stronger bonding and faster hardening. The heating process is controlled by the microcontroller, which adjusts the temperature based on the moisture levels and the specific requirements of the concrete mix. This controlled heating ensures that the concrete does not dry out too quickly which lead to cracking or weakening, but instead hardens at a steady and optimal rate that results in a more durable and structurally sound product.

[0043] The curing process is one of the most important steps in concrete production as this directly affects the strength, durability, and surface finish of the final product. By carefully controlling both the moisture and temperature during the curing stage, the device ensures that the concrete mixture is given the ideal conditions to set and harden properly. This controlled curing environment helps produce high-quality concrete tiles or other concrete products that meet the desired standards for strength and appearance.

[0044] Once the concrete is sufficiently hardened and is ready for use, an opening 119 in the front wall of the housing 101 allows the user to easily access the cured tiles or concrete products. The opening 119 provides a practical and convenient means for removing the finished product from the curing platform 116 without the need for manual handling or additional tools. The opening 119 ensures that the tiles are removed with ease for reducing the potential of damage and improving the overall efficiency of the manufacturing process.

[0045] In the case where the user specifies that the recycled foundry sand is to be utilized for road construction, the device adapts to this particular need by utilizing an electronic nozzle 120 that is linked to the second chamber 108 through a hollow pipe 121. The electronic nozzle 120 aids in transferring the blended concrete mixture from the chamber 108 to the designated area for road construction. Once the user inputs their requirements for road construction, including the desired area and the type of concrete mix, the microcontroller receives the input and activates the necessary components to ensure the smooth delivery and application of the concrete.

[0046] The microcontroller communicates with the electronic nozzle 120 to regulate the flow of the concrete mixture through the hollow pipe 121. The nozzle 120 is developed to be highly adaptable which is capable of adjusting the amount of concrete dispensed and the distribution pattern to suit the specific road construction needs. This ensures that the blended concrete mixture is spread evenly and precisely across the area designated for the road, whether this involves creating a foundation layer, a surface coating, or any other part of the road construction process. The hollow pipe 121 serving as the conduit 115, connects the nozzle 120 to the second chamber 108 where the concrete mixture is thoroughly blended for allowing the paste to be transferred directly to the nozzle 120 for distribution.

[0047] In addition to the precise control over the amount of concrete dispensed, the nozzle 120 and the microcontroller are configured to accommodate the varying conditions of the construction site, such as road width, surface texture, and environmental factors. For example, if the construction area requires a thicker layer of concrete in one section and a thinner layer in another, the device adjust the nozzle’s operation accordingly for ensuring that the road surface meets the required specifications.

[0048] Thus, the electronic nozzle 120 connected to the second chamber 108 and regulated by the microcontroller offers a highly efficient and precise solution for applying recycled concrete in road construction. This not only ensures the even and accurate spread of concrete across the road surface but also enhances the overall speed and efficiency of the construction process. This automated approach significantly reduces labor costs, minimizes material waste, and ensures a higher quality of work, making this an ideal solution for large-scale road construction projects that involve the recycling of foundry sand into concrete.

[0049] Lastly, a battery (not shown in figure) is associated with the system to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0050] The present invention works best in the following manner, where the user inputs details about the intended use of the foundry sand via the touch interactive display panel 103 mounted on the housing 101 which is positioned on the ground surface. The microcontroller, connected to the display panel 103, processes the input and activates the first motorized mixing unit 104 inside the first chamber 102, which rotates in both clockwise and counter-clockwise directions to reduce the sand particles to the fine size. The sand is then discharged through motorized iris holes 105 onto the sieve plate 106, where the vibrating unit 109 ensures even spread, and the primary heating unit 110, in collaboration with the moisture sensor, adjusts the moisture content of the sand to match regular sand. The sieved sand is transferred to the second chamber 108, where multi-sectioned container 111 hold raw materials such as cement, water, and aggregates. The microcontroller dynamically controls motorized iris unit 112 to dispense precise amounts of these materials into the second chamber 108. The second motorized mixing unit 113 blends the materials with the sand. The blended paste is then transferred via the electronic valve 114 through the conduit 115 onto molds placed on the curing platform 116. The platform 116 maintains the desired moisture level using the water vessel 117 and electronic spout, while the secondary heating unit 118 gradually raises the temperature to ensure proper hardening of the paste into tiles. Once the tiles are formed, the opening 119 on the housing 101 allows the user to easily retrieve them. If the user specifies road construction as the purpose, the microcontroller activates the electronic nozzle 120 to spread the blended concrete in the required area.
