The piston 9 supports one end of the push rod 7, so that the push rod 7 is not easy to shake when moving. When the push rod 7 moves toward the electromagnet 5, the sealing ring 29 cleans the surface of the push rod 7, making it difficult for the raw material to enter the interior of the mounting tube 4. When the filtering effect of the filter cartridge 11 decreases, the electromagnet 5 is powered off, and the push rod 7 is driven away from the electromagnet 5 under the action of the elastic force of the spring 6, further making the cleaning brush 10 fit against the inner wall of the filter cartridge 11. The filter cartridge 11 rotates so that the cleaning brush 10 scrapes the inner wall of the filter cartridge 11, thereby cleaning the filter cartridge 11.

[0037] In this embodiment, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The top of the filter cartridge 11 is fixedly connected with a feed seat 12, and the raw materials are added to the filter cartridge 11 through the feed seat 12. A discharge pipe 13 is arranged inside the filter cartridge 11, and a solenoid valve is arranged on the discharge pipe 13. After the inner wall of the filter cartridge 11 is cleaned, impurities are discharged from the discharge pipe 13. A filter screen is arranged on the side of the filter cartridge 11. The top and bottom of the filter cartridge 11 are both sealed circular plates.

The inner wall of the second bearing seat 21 is provided with a lower bearing 22. The first bearing seat 14 limits the position of the feed seat 12 through the upper bearing 15, thereby limiting the top of the filter cartridge 11. The second bearing seat 21 limits the position of the exhaust pipe 13 through the lower bearing 22, thereby limiting the bottom of the filter cartridge 11. The filter cartridge 11 is not easy to shake when rotating. The inner wall of the second bearing seat 21 is rotatably connected to the exhaust pipe 13 through the lower bearing 22.

The driving motor 17 drives the first gear 18 to rotate, and the meshing transmission of the first gear 18 and the second gear 16 drives the impurity discharge pipe 13 to rotate, so that the filter cartridge 11 rotates, and the raw materials inside the filter cartridge 11 are centrifuged. Under the action of the brush 10, the raw material moves to the inner wall of the filter cartridge 11, so that the raw material is filtered by the filter cartridge 11. The filtration speed of the raw material is increased under the action of centrifugal force. When the inner wall of the filter cartridge 11 is cleaned, the rotation speed of the drive motor 17 is reduced, thereby reducing the rotation speed of the filter cartridge 11, so that the remaining raw material and impurities move to the bottom of the filter cartridge 11 under the action of gravity, and the impurities on the inner wall of the filter cartridge 11 are scraped off by the cleaning brush 10. The scraped impurities also move to the bottom of the filter cartridge 11 under the action of gravity, and the impurities are then discharged from the impurity discharge pipe 13.

Under the action of the elastic force of the spring 6, the push rod 7 is driven away from the electromagnet 5, so that the cleaning brush 10 is further fitted with the inner wall of the filter cartridge 11. The push rod 7 pushes the cleaning brush 10 to fit with the inner wall of the filter cartridge 11, and the inner wall of the filter cartridge 11 is cleaned during the rotation of the filter cartridge 11.
