The sewage is filtered by the filter cylinder 2, and the sundries remain inside the filter cylinder 2. At the same time, the filtering mechanism works to make the scraper 12 scrape the remaining sundries, so that the sundries fall off;

[0034] Among them, in order to achieve the purpose of filtering and removing slag, the present device adopts the following technical solutions: The filtering mechanism further includes a positioning shaft 7, which is embedded inside the other end of the filtering cylinder 2. The positioning shaft 7 is movably connected to the filtering cylinder 2 through a rolling bearing.

One end of the square rod 8 is fixedly connected to two positioning frames 9. Inside both of the two positioning frames 9, there are movable rods 10. Inside both of the two movable rods 10, there is a rotating rod 11 fixedly embedded. The rotating rod 11 is movably connected to the positioning frame 9 through a damping bearing. The outer ends of both of the two movable rods 10 are fixedly connected to scraping plates 12, and both of the two scraping plates 12 communicate with the inner wall of the filtering cylinder 2. A moving frame 13 is sleeved outside one end of the square rod 8. Inside the moving frame 13, there are two blocking rods 14 fixedly embedded. Both of the two blocking rods 14 slide relative to the square rod 8. One end of both of the two blocking rods 14 extends to the outside of the square rod 8, and both of the two blocking rods 14 are arranged on one side of both of the two movable rods 10. One side of the moving frame 13 is fixedly connected to a spring 15, and the spring 15 is sleeved outside the square rod 8. Inside the inner side of the feed pipe 3, there are two baffle plates 16 fixedly embedded. Both of the two baffle plates 16 are arranged on the other side of both of the two movable rods 10. Inside the inner side of both of the two positioning frames 9, there is a blocking block 17 fixedly connected. The filtering mechanism further includes a driving motor 18, which is arranged on the front side of the filter water tank 1. The output end of the driving motor 18 is fixedly connected to a transmission shaft 19. Outside the transmission shaft 19, there is a gear 20 fixedly sleeved. One side of the gear 20 extends into the filter water tank 1. Inside the filter water tank 1, there is a toothed ring 21 fixedly sleeved outside the filtering cylinder 2. The toothed ring 21 is meshed and connected with the gear 20. On the rear side of the filter water tank 1, there is a transmission rod 22.

[0035] The user starts the drive motor 18 to work. The operation of the drive motor 18 drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 drives the gear 20 and the gear ring 21 to rotate. The rotation of the gear ring 21 drives the filter cylinder 2 to rotate, making the sewage filtration effect better. At the same time, the rotation of the transmission shaft 19 drives the sprocket 27 and the transmission rod 22 to rotate. The rotation of the transmission shaft 19 and the transmission rod 22 drives the reciprocating lead screw 23 to rotate. The rotation of the reciprocating lead screw 23 drives the sliding block 24 and the cross plate 25 to move. The movement of the cross plate 25 drives the first magnet 26 to move. When the first magnet 26 contacts the second magnet 28, they attract each other. When the first magnet 26 moves in the reverse direction, it drives the second magnet 28 and the square rod 8 to move. The movement of the square rod 8 drives the movable rod 10 and the scraper 12 to move, so that the scraper 12 scrapes the inside of the filter cylinder 2, and the sundries fall from the two through slots 6, facilitating the user to collect. When the square rod 8 moves to the maximum limit, the moving frame 13 is resisted and moves. The movement of the moving frame 13 drives the stop rod 14 to move and resist the movable rod 10, so that the movable rod 10 and the scraper 12 rotate, so that the scraper 12 does not fit against the inner wall of the filter cylinder 2. When the square rod 8 moves back, the sundries will not be pushed back into the filter cylinder 2, making the slag cleaning efficiency higher. When the square rod 8 moves back to the maximum limit, the baffle 16 resists the movable rod 10, so that the movable rod 10 and the scraper 12 return to their original positions, making the scraper 12 closely adhere to the inner wall of the filter cylinder 2 again, facilitating the next scraping work;

[0036] Among them, in order to achieve the purpose of supporting and limiting, the following technical solutions are adopted in this device: Fixed blocks 29 are provided on both the front and rear sides of the filter water tank 1. Limiting rods 30 are fixedly connected to the outer sides of the two fixed blocks 29. One end of the two limiting rods 30 is fixedly connected to a fixing plate. Limiting blocks 31 are provided on the outer sides of the two sliding blocks 24. The two limiting blocks 31 are respectively sleeved on the outer sides of the two limiting rods 30, and the limiting blocks 31 slide relative to the limiting rods 30. A water outlet pipe 32 is provided on one side of the filter water tank 1, a material receiving box 33 is provided on the other side of the filter water tank 1, and a cover plate 34 is provided on the front side of the filter water tank 1.

[0037] The usage process of the present invention is as follows: The user discharges sewage from the material receiving hopper 5. At this time, the driving motor 18 is started to work. The sewage is filtered by the filter cylinder 2, and the sundries remain inside the filter cylinder 2. At the same time, the filtering mechanism works, and the scraper 12 scrapes the remaining sundries, causing the sundries to fall. The user starts the driving motor 18 to work. The driving motor 18 drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 drives the gear 20 and the gear ring 21 to rotate. The rotation of the gear ring 21 drives the filter cylinder 2 to rotate, making the sewage filtering effect better. At the same time, the rotation of the transmission shaft 19 drives the sprocket 27 and the transmission rod 22 to rotate. The rotation of the transmission shaft 19 and the transmission rod 22 drives the reciprocating lead screw 23 to rotate. The rotation of the reciprocating lead screw 23 drives the sliding block 24 and the cross plate 25 to move. The movement of the cross plate 25 drives the first magnet 26 to move. When the first magnet 26 contacts the second magnet 28, they attract each other. When the first magnet 26 moves in the reverse direction, it drives the second magnet 28 and the square rod 8 to move. The movement of the square rod 8 drives the movable rod 10 and the scraper 12 to move, so that the scraper 12 scrapes the inside of the filter cylinder 2, and the sundries fall from the two through slots 6, facilitating the user to collect. When the square rod 8 moves to the maximum limit, the moving frame 13 is resisted and moves. The movement of the moving frame 13 drives the stop rod 14 to move and resist the movable rod 10, causing the movable rod 10 and the scraper 12 to rotate, so that the scraper 12 does not fit against the inner wall of the filter cylinder 2. When the square rod 8 moves back, the sundries will not be pushed back into the filter cylinder 2, making the slag cleaning efficiency higher. When the square rod 8 moves back to the maximum limit, the baffle 16 resists the movable rod 10, causing the movable rod 10 and the scraper 12 to return to their original positions, making the scraper 12 tightly adhere to the inner wall of the filter cylinder 2 again, facilitating the next scraping work.
