THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE SUBJECT MATTER AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

REFERENCE TO RELATED APPLICATION:
[001] The invention disclosed in the application is a divisional application of the invention disclosed and claimed in the specification of the Patent Application No. 202321089817, and claims priority under section 16 of the Patents Act, 1970
FIELD
[002] The present disclosure relates to the field of dispersion systems. More particularly, the present invention relates to systems and equipment for said dispersion system.
BACKGROUND
[003] Dispersion is an important and vital process that is required to be performed in the stock preparation process in order to achieve the desired type of fiber to manufacture the intended paper from the pulp or the raw material. In said dispersion system the raw material has to pass through a plurality of stages which include but not limited to thickening, dewatering, cooking, and swelling in order to achieve desired properties and characteristics. Whereas, in a conventional dispersion system the input of pulp is limited to a range of 4% to 10% consistency and is required to convert into 40% consistency with contamination dilution in order to diminish said contamination from final output. Wherein said process of dispersion commences with the input in the form of pulp or slurry to the screw press with 4 to 10% of consistency to get output with 25 to 30% of consistency in order to feed inputted slurry with 28% to 30% the form of pulp to provide input to the Plug screw in order to convey the material from said screw press to shredding device with consistency 28 to 30% in order to perform the swelling of the pulp comprising fibers to increase size and softening of fiber approx. at 120 degrees of temperature. After said shredding said softened and swelled input can be fed to heating and mixing the device in order to perform further swelling and softening of fiber to disperse the fiber by means of releasing the boding of fiber and feeding said softened solution to infeeder for further processing and input to disperser to rubbing of fiber without damaging the fiber. In said depression system the steam is required to plug precisely to perform said swelling action effectively at higher temperatures and in case any leakage can cause inappropriate swelling and dispersion.
[004] However, in the conventional system, there is no provision for water handling and managing consistency in accordance with the shredder, heating, and mixing device. Further, the amount of unintended water from the plug will remain as it is the system to restricts the improvement of further consistency and efficacy of said dispersion system to 30% consistency only. Therefore, said dispersion system requires a heavy size of equipment and parts to perform dispersion which leads said dispersion process fail to become energy-intensive and affects the overall cost of paper production adversely.
[005] Hence, there is a technical gap that is required to be fulfilled by employing an effective and efficient dispersion system with optimum performance and alleviating the above-mentioned drawbacks.
OBJECTS
[006] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
[007] An object of the present disclosure is to articulate an effective and efficient dispersion system.
[008] The other object of the present disclosure is to provide precise plugging and dewatering configurations for said dispersion systems.
[009] Another object of the present disclosure is to optimize the steam consumption for said dispersion system.
[010] Still other object of the present disclosure is to facilitate effective water management and improve the dewatering capacity for said dispersion system.
[011] Yet another object of the present disclosure is to increase the consistency of said dispersion system.
[012] Still, another object of the present disclosure is to reduce energy consumption for said dispersion system.
[013] Yet another object of the present disclosure is to design lightweight compact devices for said dispersion system.
[014] Moreover, the object of the present disclosure is to reduce the pulp and paper-making cost with improved quality of pulp and/or paper.
[015] Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

In one of the embodiments said hopper (303) can be opened more than 80% length of said straight part (304a) to allow maximum input of raw material and peripheral other sides of said housing (305) covered with or without holes (306). Further, said tapered zone (302) commences from said juncture (312) to a juncture (313), wherein said screw flights (304d) and said housing (305) also reduce peripheral diameter from said juncture (312) to a juncture (313) to perform the plugging and dewatering of said feed material, whereas the water extracted during said dewatering process can be removed from the plurality of holes (306) provide on periphery of said housing (305) in said pressure zone (305). In another embodiment said housing (305) and said screw (304) can be tapered in angle (A) in order to perform the effective dewatering and simultaneous plugging operation. In one of the preferred embodiments said angle (A) can be in the range of 2° to 6° and preferably 3° to 5°. Furthermore, said shredding zone (309) can commence from said juncture (313) to the end (314) opposite to said juncture (313) of said dewatering, plugging, and shredding device (300), wherein said screw (304) suddenly increases the size of said flight (304d) to said flight (304h) equivalent or larger than the flight (304d) appears in said transfer zone (301) to continue in same size till to the end (314) opposite to said juncture (313) of said dewatering, plugging, and shredding device (300), whereas said screw (304) in said shredding zone (309) can be cover with said housing (305) configured with said steam inlet (310) on straight periphery circular in cross-section instead of tapered periphery in said pressure zone (302) and/or hopper (303) in said transfer zone (301). In one of the embodiments, the diameter of said housing (305) in said shredding zone (309) can be larger than the diameter of said housing (305) at said juncture (313) and equal to or larger than the diameter of said housing (305) at said juncture (312) without said holes (316). However, in order to inject said steam evenly or decrease configuration height and/or streamline the configuration of piping in said shredding zone (309) said steam inlet (310) can be configured in an inclined manner at an angle (B). In one of the embodiments said angle (B) can be greater than 15° and smaller than 90° and preferably can be in the range of 30° to 60°. Moreover, said housing (305) and said screw (304) can be configured in homogeneous or split form, wherein said hopper (303), said tapered housing (305)can be replaced as a screen configured within said juncture (312, 313), and said housing (305) can be configured separately with said steam inlet (310) and even periphery to formulate replaceable configuration of said housing (305), whereas screw (305) can be configured in split form configured at a juncture (304i). In one of the embodiments said juncture (304i) can be designed to be positioned in said transfer zone (301) to reduce failure or said screw (304) breakage possibilities and facilitate a longer life without failure or bending in order to perform the effective operation. In one of the preferred embodiments said holes (306) can be of a type that includes but not limits to the inverted hole, inverted counter hole, counter hole, axial hole, etc. In another embodiment said opening (304h) includes sharp edges in order to perform said shredding action effectively and transfer material at a greater pace to enhance the efficacy and efficiency of said dewatering, plugging, and shredding device (300). In another embodiment the configuration of said shredding zone (309) next to said pressure zone (302) enhances the plugging effect due to the increase in the size of said screw flight (304f) and the material travel length in said shredding zone (309) that result into increase in the effect of said pressure zone (302) in said shredding zone (309) as well to perform effectively. Further, the increase in said travel distance for said feed material in said shredding zone (309) results in an increase in the push force for the feed material transfer which leads to enhancing the dewatering effect to increase the overall output consistency in order to alleviate the efficacy and efficiency of said dewatering, plugging, and shredding device (300) at lower cost and process time.
[030] In a further embodiment as shown in Figure No. 07 to 10; a dewatering device (400) capable of performing dewatering and simultaneous plugging can be used for high-consistency (more than 40%) used in pulp production without dispersion effect by configuring said dewatering device (400) directly next to said screw press (101) to allow input of inlet material in said dispersion system (100) and generating output directly from said dewatering device (400) without configuration of said shredder (103), said heating and mixing device (104) and said dispersion device (105), wherein said dewatering device (400) can alleviate said consistency more than 40% due to the flexible configuration of a Plugging means (410) and a wear compensation mechanism (418) to maintain the pressure level and clearance between a screw flight (404d) and a housing (405) in a pressure zone (402) to increase the dewatering for said dewatering device (400) in accordance to the desirable consistency. Further, a material can be fed from a hopper (403) in said transfer zone (401) having a screw (404) with straight part (404a) of the flights (404d) which act as an infeeder to transfer said feed material to said pressure zone (402) having said screw (404) with tapered part (404b) of said flights (404d) to perform the dewatering and plugging and transfer the pressurized material.

Whereas the walls (403c) of said hopper (403) are curved and inclined in shape in order to gradually reduce from said opening (403a) to said opening (403b) to allow a large amount of inlet material and feed said inlet material compactly to said screw (404) in straight part (404a) of said transfer zone (401) for transferring to said pressure zone (402) with said tapered screw (404b) for removing the water content included in said feed material by means squeezing and pressurizing of said feed material against said housing (405) using said screw (404). As said feed material transferred in said pressure zone (402) with said tapered screw (404b) the squeezing forces on said material increases in accordance with the diameter of said tapered screw part (404b) and said housing (405) decreases and the clearance between said screw (404) and said housing (405). Whereas ends (404c) of said screw (404) were designed not to have said flight (404d) to allow configuration of said Plugging means (410), said wear compensation mechanism (418), and said operating means (408). In one of the embodiments said operating means (408) configure at least any of said end (404c) of the screw (404) to operate said screw (404) in order to perform the intended operation. In one of the embodiments said operating means (408) can be configured with said end (404c) opposite of said wear compensation mechanism (418) and/or said Plugging means (410). In one of the embodiments said feed material forwarded to said pressure zone (402) under the continuous action of a force (P) can be called a forward force generated due to the continuous feed of material in said hopper (403) as well as rotation of said operating means (408) and gradually increasing force (R) generated due to rotation of said screw (404). Further, in accordance with the pressure, force, and area principle the pressure is directly proportional to force, and inversely proportional to area, at a constant force, as said feed material travel through said pressure zone (402) with the configuration of said tapered part (404b) of said screw (404) and proportionally reduced size of said housing (405) effectively reduces the area to travel the same amount of material as fed in said straight part (404a) of said transfer zone (401) leads to increase in pressure which results to increase in a force (R) generated due to rotation of said screw (404) to force said feed material against said housing (405) static in position and opposite to said force (P) towards the outlet of said dewatering device (400).
