Abstract
Description
Technical Field
[0001] This utility model belongs to the field of papermaking, specifically relating to a self-cleaning papermaking pulping device. Background Technology
[0002] The pulping unit is the core equipment in the papermaking process. It is mainly used to mechanically treat pulp fibers to change their physical properties, such as length, degree of fibrillation, and swelling, thereby optimizing key performance indicators of paper such as strength, uniformity, and air permeability.
[0003] In existing papermaking pulping equipment, raw materials are typically introduced into a mixing device and mixed with water for an extended period of time to form pulp. After the process is completed, some pulp may adhere to and remain on the inner wall of the pulping device. If the pulp is not removed in time, it may become moldy and affect the subsequent pulping quality. Therefore, the inside of the pulping device needs to be cleaned. However, the internal mixing blades of common pulping devices are quite complex, resulting in a small internal space that makes it difficult to clean the inner wall of the pulping device. Furthermore, there is a risk of injury from the mixing blades during cleaning, posing a certain safety hazard. Utility Model Content
[0004] To overcome the problem of limited internal space in papermaking pulping equipment making it difficult to clean residual pulp inside the barrel, a self-cleaning papermaking pulping equipment is proposed.
[0005] The technical solution of this utility model is as follows: a self-cleaning papermaking pulping device, including a pulping tank and an annular guide rail. An annular guide rail is fixedly connected to the upper end of the pulping tank, encircling the pulping tank. The inner and outer walls of the annular guide rail are respectively provided with a limiting groove and an annular groove encircling the annular guide rail. A toothed ring is fixedly connected to the inner wall of the annular groove. A movable block is provided at the upper end of the annular guide rail. A support block is fixedly connected to the rear end of the movable block. A gear shaft is rotatably mounted between the lower inner wall of the support block and the lower end of the movable block. The gear meshes with the gear ring. An electric motor is installed at the upper end of the movable block. The output end of the electric motor passes through the upper end of the movable block and is connected to the rotating shaft of the gear shaft. A limit block is fixed at the lower edge of the movable block. A first fixing block is fixed at the lower end of the limit block. A second fixing block is installed at the lower end of the first fixing block. A roller brush is fixed at the lower end of the second fixing block. The outer wall of the roller brush is in contact with the inner wall of the pulping tank. A strip brush is fixed at the lower outer wall of the roller brush. The lower end of the strip brush is in contact with the lower inner wall of the pulping tank.
[0006] Furthermore, a limit frame is fixed to the lower end of the support block, and the inner wall of the lower end of the limit frame is in contact with the lower end of the annular guide rail.
[0007] Furthermore, the end of the limiting block near the gear shaft is in contact with the inner wall of the annular guide rail, and grooves are provided at both the front and rear ends of the limiting block.
[0008] Furthermore, a limiting wheel is rotatably installed inside the groove, with the outer wall of the limiting wheel fitting against the inner wall of the limiting groove.
[0009] Furthermore, a dovetail groove is provided at the lower end of the first fixing block, and a locking block is fixedly connected to the upper end of the second fixing block, with the dovetail groove and the locking block being compatible.
[0010] Furthermore, the front end of the first fixing block is provided with a screw hole, and the front end of the second fixing block is fixedly connected to a fixing plate, with a limit hole through the front end of the fixing plate.
[0011] Furthermore, a bolt is provided inside the limiting hole, and the bolt passes through the limiting hole and is threaded into the screw hole.
[0012] The beneficial effects of this utility model are as follows: The output end of the motor can drive the gear shaft to rotate, and the gear shaft meshing with the gear ring can drive the movable block to move in a circular motion along the inner wall of the annular guide rail. This causes the roller brush and strip brush to rotate in a circular motion against the inner wall and lower inner wall of the pulping tank, which can scrape and clean the pulp residue on the inner wall of the pulping tank, improving the efficiency of cleaning the inner wall of the pulping tank. Compared with the existing paper pulping device, the added annular guide rail and movable block can be driven by the motor, so that the movable block moves along the inner wall of the annular guide rail, thereby allowing the roller brush and strip brush to clean the inner wall of the pulping tank. This avoids workers being accidentally injured by the stirring paddle when cleaning manually, and improves the efficiency of cleaning the pulping tank. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figures 1-5 This utility model provides an embodiment of a self-cleaning papermaking pulping device, including a pulping tank 1 and an annular guide rail 2. The upper end of the pulping tank 1 is fixedly connected to the annular guide rail 2, which surrounds the pulping tank 1. The inner and outer walls of the annular guide rail 2 are respectively provided with a limiting groove 6 and an annular groove 7 surrounding the annular guide rail 2. A toothed ring 4 is fixedly connected to the inner wall of the annular groove 7. A movable block 8 is provided at the upper end of the annular guide rail 2. A support block 9 is fixedly connected to the rear end of the movable block 8. A gear shaft 10 is rotatably mounted between the lower inner wall of the support block 9 and the lower end of the movable block 8. The gear of the gear shaft 10... The gear ring 4 meshes with the gear ring 4. The upper end of the movable block 8 is equipped with a motor 3. The output end of the motor 3 passes through the upper end of the movable block 8 and is connected to the rotating shaft of the gear shaft 10. The lower edge of the movable block 8 is fixedly connected with a limit block 11. The lower end of the limit block 11 is fixedly connected with a first fixing block 15. The lower end of the first fixing block 15 is equipped with a second fixing block 16. The lower end of the second fixing block 16 is fixedly connected with a roller brush 5. The outer wall of the roller brush 5 is in contact with the inner wall of the pulping tank 1. The lower outer wall of the roller brush 5 is fixedly connected with a strip brush 17. The lower end of the strip brush 17 is in contact with the lower inner wall of the pulping tank 1.
[0021] The output of the motor 3 can drive the gear shaft 10 to rotate. The gear shaft 10 meshes with the gear ring 4 and rotates, which can drive the movable block 8 to move in a circle along the inner wall of the annular guide rail 2. This causes the roller brush 5 and the strip brush 17 to rotate in a circle against the inner wall and the lower inner wall of the pulping tank 1, which can scrape and clean the pulp residue on the inner wall of the pulping tank 1, improve the efficiency of cleaning the inner wall of the pulping tank 1, and avoid the situation where workers are accidentally injured by the stirring paddle when cleaning manually.
[0022] Please see Figure 4In this embodiment, the lower end of the support block 9 is fixedly connected to the limiting frame 14. The lower inner wall of the limiting frame 14 is in contact with the lower end of the annular guide rail 2. In use, the movement of the movable block 8 can be limited by the limiting frame 14, thereby improving the stability of the movable block 8 when it moves. The end of the limiting block 11 near the gear shaft 10 is in contact with the inner wall of the annular guide rail 2. The front and rear ends of the limiting block 11 are provided with slots 12. In use, the stability of the movable block 8 when it moves can be further improved by the limiting block 11 being in contact with the annular guide rail 2.
[0023] Please see Figures 4-5 In this embodiment, a limiting wheel 13 is rotatably installed inside the groove 12. The outer wall of the limiting wheel 13 is in contact with the inner wall of the limiting groove 6. During use, the limiting wheel 13 rotates in contact with the limiting groove 6, which can ensure the fixation and stability of the movable block 8 when it moves and prevent the gear shaft 10 from derailing. The lower end of the first fixing block 15 is provided with a dovetail groove 18, and the upper end of the second fixing block 16 is fixedly connected with a locking block 19. The dovetail groove 18 and the locking block 19 are adapted to each other. During use, the dovetail groove 18 and the locking block 19 can be used to facilitate the assembly and disassembly of the first fixing block 15 and the second fixing block 16.
[0024] Please see Figure 5 In this embodiment, the front end of the first fixing block 15 is provided with a screw hole 20, and the front end of the second fixing block 16 is fixedly connected with a fixing plate 21. The front end of the fixing plate 21 is provided with a limiting hole 22. In use, the positions of the second fixing block 16 and the roller brush 5 can be positioned by the screw hole 20 and the limiting hole 22, and the second fixing block 16 can be easily disassembled and assembled. A bolt 23 is provided in the limiting hole 22. The bolt 23 passes through the limiting hole 22 and is threaded into the screw hole 20. In use, the second fixing block 16 can be quickly disassembled by the bolt 23. During operation, the roller brush 5 and the strip brush 17 can be removed to avoid affecting the operation of the pulping tank 1.
[0025] During operation, first, start the motor 3. The output end of the motor 3 drives the gear shaft 10 to mesh with the gear ring 4 to rotate, which in turn drives the roller brush 5 and the strip brush 17 to rotate and clean the inner wall of the pulping tank 1. Then, after the inner wall of the pulping tank 1 is cleaned, turn off the motor 3 and turn the bolt 23 to disassemble it. Next, grasp the second fixing block 16 and pull the second fixing block 16 outward along the opening of the dovetail groove 18 to disassemble the roller brush 5 and the strip brush 17. Finally, pour water into the pulping tank 1 to start the pulping tank 1 to pulp and paper making operation of the raw materials.
[0026] Through the above steps, the output end of the motor 3 can drive the gear shaft 10 to rotate. The gear shaft 10 meshes with the gear ring 4 and rotates, which can drive the movable block 8 to move in a circle along the inner wall of the annular guide rail 2. This causes the roller brush 5 and the strip brush 17 to rotate in a circle against the inner wall and the lower inner wall of the pulping tank 1, which can scrape and clean the pulp remaining on the inner wall of the pulping tank 1, improve the efficiency of cleaning the inner wall of the pulping tank 1, and solve the problem that it is inconvenient to clean the pulp remaining in the tank due to the limited internal space when using the paper pulping device.
