[0004] However, when this structure is used for mixing and filtering pulp in paper processing, due to its own structural limitations, it can only perform simple mixing and filtering operations, and cannot perform efficient pulp flow operations. The pulp is prone to clumping and paper blocks, which cannot be quickly dispersed. At the same time, the equipment cannot perform efficient pulp circulation operations, which cannot meet the daily use needs. Therefore, it is urgent to design a pulp mixing and filtering device for paper processing to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a paper processing pulp stirring and filtering device to solve the problems mentioned in the background art. When using the existing structure for stirring and filtering paper processing pulp, due to its own structural limitations, it can only perform simple stirring and filtering operations, and cannot perform efficient pulp flow operations. The pulp is prone to clumping and paper blocks, which cannot be quickly dispersed, causing obstruction of discharge. At the same time, the equipment cannot perform efficient pulp circulation operations, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper processing pulp stirring and filtering device, comprising an outer processing tank, an inner processing liner inside the outer processing tank, a central feeding pipe at the center of the inner processing liner, a top seat fixedly connected to the top of the outer processing tank, and a base fixedly connected to the bottom of the outer processing tank.

[0007] A top cover and a bottom cover are provided. The top of the top seat is provided with a top cover, and the bottom of the base is provided with a bottom cover. A drive motor is provided on the surface of the top cover.

[0008] One end of the drive motor is fixedly connected to a spiral conveying roller, and a filter slurry seat is provided at the bottom end of the spiral conveying roller;

[0009] The central feed pipe has a feed pipe groove inside, and an annular filter element is provided on the side of the central feed pipe.

[0010] Preferably, the bottom end of the filter slurry seat is provided with a discharge valve seat, and the four sides of the filter slurry seat are provided with material conveying side pipes.

[0011] Preferably, the bottom end of the bottom cover is provided with a discharge base, and the bottom end of the discharge base is fixedly connected to a support base.

[0012] Preferably, the inner liner of the processing vessel has a liquid storage tank inside, and the inner wall of the liquid storage tank is provided with side filter elements on all four sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This paper processing pulp mixing and filtering device, through its outer processing tank, inner processing tank, central feeding pipe, top seat, top receiving cover, drive motor, spiral conveying roller, pulp seat, discharge valve seat, conveying pipe trough, and annular filter element, enables the equipment to simultaneously perform efficient mixing and filtering of paper processing pulp. In actual use, the operator first injects the paper processing pulp into the outer processing tank, then starts the drive motor at the top of the top receiving cover, causing the spiral conveying roller at one end to rotate clockwise inside the central feeding pipe, mixing the pulp upwards. Then, the drive motor rotates counterclockwise, rapidly conveying the pulp downwards inside the central feeding pipe. Large particle clumps are then efficiently filtered through the annular filter element on the side of the central feeding pipe, and the pulp is quickly discharged downwards through the central feeding pipe to the pulp seat and discharge valve seat. This effectively avoids blockages that could affect the conveying process, greatly improving the equipment's mixing and filtering efficiency and demonstrating the practicality of the equipment design.

[0015] This paper processing pulp mixing and filtering device, through its outer processing tank, inner processing liner, central feeding pipe, base, bottom cover, pulp filter seat, conveying side pipe, discharge base, support chassis, storage tank, and side filter elements, further improves the overall efficiency of the equipment. During daily use, operators can close the discharge valve at the bottom of the pulp filter seat, and then the pulp conveyed downwards by the spiral conveyor roller is continuously and evenly transported to the conveying side pipe on the side of the pulp filter seat. Through the base at the bottom of the outer processing tank, the pulp is evenly transported to the side filter elements on all four sides of the inner wall of the storage tank, and then evenly flows back into the inner processing liner. This, combined with the central feeding pipe, enables more efficient pulp circulation, mixing, and filtering. Furthermore, the entire inner processing liner inside the outer processing tank can be quickly disassembled and reassembled for rapid cleaning and maintenance, demonstrating the comprehensiveness of the equipment design.

[0022] Please refer to Figures 1-4, which show one embodiment of this utility model:

[0023] A paper processing pulp mixing and filtering device includes an outer processing tank 1, an inner processing liner 2 inside the outer processing tank 1, a central feeding pipe 3 at the center of the inner processing liner 2, a top seat 4 fixedly connected to the top of the outer processing tank 1, and a base 5 fixedly connected to the bottom of the outer processing tank 1. A conveying pipe groove 15 is provided inside the central feeding pipe 3, and an annular filter element 16 is provided on the side of the central feeding pipe 3. A liquid storage tank 17 is opened inside the inner processing liner 2, and side filter elements 18 are arranged on the four sides of the inner wall of the liquid storage tank 17. The pulp is evenly conveyed to the side filter elements 18 on the four sides of the inner wall of the liquid storage tank 17 through the base 5 at the bottom of the outer processing tank 1, and then evenly returned to the inner processing liner 2. This, combined with the central feeding pipe 3, enables a more efficient circulating, mixing, and filtering operation of the pulp.

[0024] The top cover 6 and the bottom cover 7 are provided. The top cover 6 is provided at the top of the top seat 4 and the bottom cover 7 is provided at the bottom of the base 5. The surface of the top cover 6 is provided with a drive motor 8. One end of the drive motor 8 is fixedly connected to a spiral conveying roller 9.

The four sides of the filter seat 10 are provided with conveying side pipes 12. The bottom end of the bottom cover 7 is provided with a discharge base 13. The bottom end of the discharge base 13 is fixedly connected to a support base 14. The spiral conveying roller 9 at one end rotates clockwise inside the central feeding pipe 3 to stir and mix the slurry upwards. Then the drive motor 8 rotates counterclockwise to quickly convey the slurry downwards inside the central feeding pipe 3.

[0025] Working Principle: During operation, the operator first injects the paper processing pulp into the outer processing tank 1. Then, the drive motor 8 at the top of the top cover 6 is started, causing the spiral conveyor roller 9 at one end to rotate clockwise inside the central feeding pipe 3, mixing the pulp upwards. The drive motor 8 then rotates counter-clockwise, rapidly conveying the pulp downwards inside the central feeding pipe 3. Large particles are then efficiently filtered through the annular filter element 16 on the side of the central feeding pipe 3, quickly discharging the pulp down the central feeding pipe 3 to the filter seat 10 and the discharge valve seat 11. This effectively prevents blockages that could affect the material conveying process and greatly improves the equipment's efficiency. In daily use, to improve the mixing and filtration efficiency of the slurry, the operator can close the discharge valve seat 11 at the bottom of the filter slurry seat 10, and then the slurry conveyed downward by the spiral conveying roller 9 will be evenly conveyed to the side conveying pipe 12 on the side of the filter slurry seat 10. Through the base 5 at the bottom of the outer processing tank 1, the slurry will be evenly conveyed to the side filter cores 18 on the four sides of the inner wall of the storage tank 17, and then evenly flowed back to the interior of the inner processing tank 2. In conjunction with the central feeding pipe 3, the slurry will be more efficiently circulated, mixed and filtered. At the same time, the inner processing tank 2 inside the outer processing tank 1 can be quickly disassembled and assembled for quick cleaning and maintenance. The above is the complete working principle of this utility model.
