DESC:FIELD OF INVENTION
[001] The present invention relates to a conical mixer. Particularly, the present invention relates to a vertical feed conical mixer with auger impellers to provide an improved mixing workability and propagation of the material in horizontal direction.
BACKGROUND OF THE INVENTION
[002] Nowadays, advancement in technology has significantly contributed in growth and development of the industrial sector. Such advancement involves simplifying complicated and time taking processes in pharmaceutical, food and chemical industries. One such advancement includes development of conical screw mixer which aids in gentle and efficient mixing of moist dry and viscous material along with displacement of products. The conical screw mixture also ensures accuracy without deterioration of the product. However, there exist a need for advanced technology capable of performing multiple functions simultaneously, thereby saving time and simplifying overall process.

[003] Various technologies exist for simplifying complicated processes in various industries. One such conventional technique includes the use of auger for boring in soil for planting shrubs, trees, plants and/or for digging post holes. The cutting devices at the bottom of an auger are known as auger blades. Some auger blades are serrated to aid bite into extremely hard materials, while others are smooth and suitable for use on softer surfaces. The augers are also used in composting process. Composting is a type of solid waste disposal in which agricultural wastes, poultry and animal excrement, home garbage, and other waste are transformed into fertilizer. The agitating auger plays dual parts to stir and carry in process of composting. The different designs of auger blades, helps to propagate the materials through rotation of blades. However, the existing auger blades are not suitable for mixing or blending of materials to achieve better composition of feed material. Existing mixers used for mixing of materials, are available in many different configurations including horizontal augers, reel type arrangements, and vertical augers. The existing augers were typically designed to compromise between mixing efficiency, discharge efficiency, and horsepower. One existing auger system uses two identical augers within a same mixer. However, the presence of identical augers in the same mixer results in limited interaction of the feed materials between the augers.

The invention relates to a drilling device for producing a borehole in the ground with a drilling tool driven in a rotating manner for removing ground material and a container for receiving the removed ground material, wherein the container has a lower feed opening, through which the removed ground material can be introduced into the container. It is envisaged that the drilling tool comprises at least one drill flight arranged below the container and that in an inlet area to the container between the drill flight and the feed opening an inlet section is provided, the pitch of which is increased with respect to a pitch of the drill flight.

[005] US7520457B1 relates to an automated composting system. The system composting system with a digestion chamber, an auger shaft with at least one mixing vane, and a power unit. The power unit can be hydraulic and can also power a shredding unit and an input conveyor system. A barrier wall can be interposed between those elements and the digestion chamber. The digestion chamber can be divided into sub chambers, and sequentially lower apertures can promote a progression of organic material. A malfunction sensor can sense a malfunction of the auger shaft, the shredding unit, or another component. A malfunction report can be provided, including to a remote receiver. The report can include a determined location of the composting system and can be directed to a selected receiver based on the malfunction. Fluids, including gasses and liquids, can be introduced by a supply source in combination with apertures along the auger shaft and/or a mixing vane.

[006] Existing mixers can either blend the material or compress the material, which takes a lot of time and double effort. Therefore, a conical mixer with improved mechanism is required to overcome the aforesaid limitations. The present invention provides one such conical mixer designed with an additional auger impeller, which improves the workability at mixing and propagating the compost materials.

[0020] In the present invention, Figure 1 illustrates a vertical feed conical mixer (100) with anchor/ auger impellers (106) integrated inside the conical mixer (100). The conical mixer (100) comprises of conical blade (102) and curved edges (104). The conical blade (102) is chamfered at the edges to aid propagation. The conical blade further comprises of an outer thread (108) and an inner thread (110). Said conical blades and curved edges are used to provide rigorous mixing and propagation of the material in the horizontal direction with binders, adhesives and water. The conical blade (102) is configured to push material in forward direction. In an exemplary embodiment, the conical blade (102) is encased inside the conical casing (112) with scaled up dimension. In an exemplary embodiment, the conical blade (102) used in the conical mixer (100) is made up of aluminum material that reduces the manufacturing cost and increases the durability of the blade (102).

[0021] The threads (108 and 110) of conical blade (102) are configured with curved edges (104) that assists in pushing the material in forward direction. In a preferred embodiment, the conical blade is configured such that the trailing/ curved edge (104) of the blade is thickened by widening the gap between the ventral side and the back side of the blade with a sharp trailing edge.

[0022] In a preferred embodiment of the present invention, Figure 2 illustrates the conical mixer (100) with scaled up dimensions. The conical blade’s outer thread (large diameter) (108) is in the range of 300-310 mm, the inner thread (small diameter) (110) is between 185-195mm and the length (109) is between 895-905mm. The conical blade (102) geometry is provided with a plurality of rod profiles (106) installed in between the threads (108 and 110) of the blade which aids in mixing of compost materials with binders, adhesives and water. As per this embodiment, the rod profiles (106) are configured with a rectangular blade (114) which have a length of 50-60mm, a width of 10-20mm and a height of 10-20mm. The rectangular blade (114) is configured to be attached at the end of the rod profiles (106), wherein the rectangular blade is attached 5-15mm away from the rod profiles (106). The rectangular blade (114) is attached perpendicular to the axis of the rod profiles (106) and parallel to the axis of the conical blade (102). The sizes of the conical blade (102) and conical chamber (118) in the present invention can be scaled up or scaled down according the space requirements and production capacity demand.

[0023] An auger impeller (106) provided in the present invention, is integrated between the conical blades (102) of the mixer (100). The auger impeller (106) comprises with a plurality of rods connected with a rectangular blades (114). The rods arrangement of the auger impeller (106) assists in mixing and blending of compost material. The auger impeller blades/ rectangular blades (114) are incorporated into the horizontal support that aids in the vertical movement of the product.

[0024] In an exemplary embodiment of the present invention, a predetermined amount of compost, binder, adhesives and water are added into a separate container. The mixture of the container is then added into the input chamber (118), which is configured to be controlled with the help of IoT. Further, on receiving the mixture of compost, binder, adhesives and water from the container to the chamber, the rectangular blade (114) starts blending the received composition and propels it forward using the conical blade (102) while being compressed due to the conical nature of the casing.

[0025] The horizontal support/ rod in the present invention, is connected with a motor through a belt drive that helps in providing vertical movement of the impeller (106). The rectangular blades (114) and the auger impeller (106) are fixedly connected to the horizontal support with the help of welding. The horizontal support is used to move the blades (114) and impeller (106) in a circular motion which thoroughly mixes and propels the mixture forward. The motor coupled with the horizontal support of the conical mixer (100) is configured to rotate the blade and auger impeller in forward and reverse direction. Said motor is driven with the help of power supplied from any preferred power source, such as but not limited to solar/ regular electricity. The motor rotates the conical mixer (100) and auger impeller (106), so that the conical blade (102) and auger impeller (106) provides simultaneous mixing and propagation of compost materials.

[0026] In another embodiment of the present invention, the vertical feed conical mixer (100) is mounted with an input chamber (118) on the top of the mixer. The input chamber (118) equipped with an IoT allows precise addition of binders, adhesives, and water to the conical chamber. The motor actuates automatically with the help of IoT and blends and propels the mixture once the IoT detects predetermined/ precise amount of mixture into the conical chamber.

[0027] In an exemplary embodiment, the auger impeller (106) are designed for higher viscosity materials that follows the shape of the chamber with minimal gap between outside of the conical blade (102) and the wall of the chamber.

[0028] The auger impeller (106) integrated inside the conical blade (102) facilitates simultaneous mixing and propagation of compost materials along with a binder material, water and a buffer material (to maintain pH of compost) from high diameter area to low diameter area of the chamber. The present invention provides simultaneous mixing and compressing of the materials to retain binding of materials after extrusion. The conical blade (102) with curved edges pushes the mixture forward, which increases the bulk density in the blending chamber.

[0029] The advantages of the present invention includes:

• simultaneous operation of the conical mixer (100) and auger impeller (106) increases the overall efficiency of the mixer (100)
• control valves provided in the present invention helps to regulate the speed of the conical mixer (100), thereby enabling the user to change the speed of the blades depending upon the need of the user;
