A rotating shaft 6 is fixedly connected to the rear side of each of the two sprockets 5. One end of each of the two rotating shafts 6 passes through the support base 7 and is rotatably connected to the support base 7. A drive motor is fixedly connected to the top of the mounting plate 2, and the output end of the drive motor is fixedly connected to one of the rotating shafts 6. The two sprockets 5 are connected by a chain 500. One of the sprockets 5 has a vertical frame 8 on its front side. A slider 9 is slidably connected inside the vertical frame 8. A connecting rod 10 is rotatably connected to the middle of the slider 9. One end of the connecting rod 10 is fixedly connected to the chain 500. A cross rod 11 is fixedly connected to the bottom of the vertical frame 8. A cross groove 200 is opened on the top of the mounting plate 2. The cross rod 11 is set inside the cross groove 200 and slidably connected to the mounting plate 2. A scraper 12 is provided at the bottom of the cross rod 11. A connecting block 13 is installed at the bottom of the cross rod 11 and the top of the scraper 12. The two connecting blocks 13 are fixed together by bolts. A collection structure is provided on the outside of the pool body 1.

[0018] The filter structure includes two connecting plate frames 4, both of which are fixedly connected to the bottom of the mounting plate 2. The two connecting plate frames 4 are symmetrically distributed with respect to the vertical center line of the mounting plate 2. A filter plate 3 is fixedly connected between the two connecting plate frames 4, and the filter plate 3 is set inside the pool body 1.

[0019] Specifically, the pulp is filtered through filter plate 3. The drive motor is started. The model of the drive motor is not specifically limited, but is adapted to the equipment position. The output end of the drive motor drives one of the sprockets 5 to rotate through one of the rotating shafts 6. The two sprockets 5 are connected by a chain 500. The chain 500 drives the slider 9 to slide inside the vertical frame 8 through the connecting rod 10. The vertical frame 8 slides inside the cross rod 11. Therefore, the vertical frame 8 drives the scraper 12 to work back and forth through the cross rod 11. The scraper 12 can push the impurities accumulated on the filter plate 3 back and forth, which can avoid the filter plate 3 from clogging during use and facilitate the passage of pulp.

[0020] Example: Figure 1 , Figure 2 and Figure 4 As shown, the lifting structure includes multiple hydraulic rods 15, all of which are fixedly connected to the outside of the pool body 1, and the top ends of the multiple hydraulic rods 15 are fixedly connected to the mounting plate 2.

[0021] The collection structure includes a bidirectional screw 16, which is located on one side of the pool body 1. One end of the bidirectional screw 16 passes through the pool body 1 and is rotatably connected to the pool body 1. A forward and reverse motor is fixedly connected to one side of the pool body 1, and the output end of the forward and reverse motor is fixedly connected to the bidirectional screw 16. Movable plates 17 are threadedly connected to both ends of the outer side of the bidirectional screw 16. T-shaped rods 18 are slidably connected to both movable plates 17. One end of each T-shaped rod 18 is fixedly connected to the pool body 1. Placement boxes 19 are fixedly connected to the top of each of the two movable plates 17. Collection boxes 20 are provided inside each of the two placement boxes 19. Handles are installed on both sides of each collection box 20.

[0022] Specifically, when it is necessary to clean the impurities on the filter plate 3, multiple hydraulic rods 15 are activated, and the multiple hydraulic rods 15 lift the mounting plate 2. The mounting plate 2 drives the filter plate 3 to move upward through the two connecting plate frames 4, moving the filter plate 3 to a position higher than the two collection boxes 20. Then, the forward and reverse motors are driven. The specific model of the forward and reverse motors is not limited, but depends on the compatible equipment. The output end of the forward and reverse motors drives the bidirectional screw 16 to rotate. The bidirectional screw 16 is threadedly connected to the two moving plates 17. The two moving plates 17 slide on the two T-shaped rods 18. Therefore, the two moving plates 17 drive the two placement boxes 19 to move in opposite directions, and adjust the two collection boxes 20 to be below the filter plate 3. With the cooperation of the scraper 12, the impurities on the filter plate 3 can be scraped from both ends of the filter plate 3 into the two collection boxes 20 for collection.
