The filter hole 502 corresponds to the filter hole 502. A liquid inlet pipe 504 is installed on the top of the top plate 503. The liquid inlet pipe 504 penetrates into the interior of the movable cylinder 505. A scraper 507 is installed inside the movable cylinder 505. The outer wall of the scraper 507 is in close contact with the inner wall of the movable cylinder 505. A drainage top cone 508 is installed on the top of the scraper 507. The drainage top cone 508 is set in a conical shape. A cylinder 509 is installed on the top of the top plate 503. The output end of the cylinder 509 penetrates into the interior of the movable cylinder 505. The output end of the cylinder 509 is fixedly connected to the scraper 507. A side strip 510 is installed on one side of the fixed cylinder 501. The strip 510 is provided with a screw groove 511 inside, and the screw groove 511 penetrates to the top of the side strip 510.
