[0022] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0023] Example: As shown in the accompanying drawings, during use, the material enters the housing 1 through the feed pipe 3. At this time, the first valve 22 is closed, the water inlet valve 19 is closed, and the drain valve 21 is closed. The first computer is started, and the first motor 12 drives the shaft 13 to rotate. The shaft 13 drives the rotating plate 6 to rotate, and the rotating plate 6 drives the stirring rod 7 to rotate around the shaft 13, thereby stirring and mixing the material. While the shaft 13 is rotating, the moving gear 8 meshes with the fixed gear 10, causing the rotating plate 6 to rotate simultaneously with the moving gear 8. 8. Under the action of the meshing of the fixed gear 10, the shaft 13 rotates, which causes the stirring rod 7 to rotate on its own axis while revolving around the revolution, which in turn causes the stirring blades 9 to rotate and mix the materials. After mixing is completed, the second motor 14 is started, which drives the screen cylinder 15 to rotate. At this time, the first valve 22 is opened, which allows the mixed materials to enter the screen cylinder 15 through the guide tube 17. The rotation of the screen cylinder 15 filters the materials. The discharge pipe 4 is fixedly installed with a discharge valve. When the discharge valve is opened, the filtered materials are discharged through the discharge pipe 4. When the screen cylinder 15 needs to be cleaned, close the first valve 22 and the discharge valve, open the drain valve 21 and the inlet valve 19, and introduce external water into the filter box 2 through the inlet pipe 18. Through backwashing, the impurities in the screen cylinder 15 are discharged through the drain pipe 20.
