[0023] This application can explain its functional principle through the following operation methods:

[0024] During use, sewage is passed into the drum 30, and pollutants in the sewage are blocked by the filter screen on the surface of the drum 30. When there are too many impurities on the filter screen and it needs to be cleaned, the drive motor 5221 on one side of the filter box 10 is started, so that the output shaft of the drive motor 5221 drives the mounting base 20 and the drum 30 to rotate through the connecting shaft, and the water pump on the side of the fixed base 40 inputs water from the water inlet pipe into the liquid separation pipe 511, and then inputs water from the liquid separation pipe 511 to the multiple nozzles 512 for spraying, so as to clean the filter screen on the surface of the drum 30, and the rotation of the connecting shaft drives the rotation of the sprocket 5222, so that the chain 5223 meshing with it on the outside rotates accordingly, thereby driving the other sprocket 5222 to rotate, and the synchronous rotation of the two sprockets 5222 allows the mounting base 20 and the rotating shaft 5211 to rotate synchronously, and the rotation of the rotating shaft 5211 drives The multiple cams 5212 rotate, so that the movable plate 523 moves inside the cavity 70. When the movable plate 523 moves, the connecting blocks 5213 and the springs 5215 on both sides of the movable plate 523 move synchronously. The elastic force of the springs 5215 during movement enables the movable plate 523 to always be in close contact with the multiple cams 5212, so that the rotation of the cams 5212 can drive the movable plate 523 to move back and forth, thereby causing the insertion rod 524 and the contact 525 on the movable plate 523 to move back and forth. The contact 525 reciprocally strikes the filter screen on the surface of the drum 30 to shake off the stains on the filter screen, and the filter screen is cleaned with the water sprayed from the nozzle 512. When the drum 30 rotates, the cleaning brush 53 in close contact with the filter screen outside the drum 30 cleans the stains on the filter screen as the drum 30 rotates, so as to prevent the filter screen from being blocked and improve the cleaning efficiency.
