At the same time, the rotating movable plate (52) drives the movable plate (52) to move up and down through the sliding action of the slider (57) and the circulation groove (56). The two movable plates (52) approaching each other drive the hinged rod (53) to change their angles. The two hinged rods (53) in the same vertical direction push the same pressure plate (58) to move, thereby driving the pressure plate (58) to squeeze the sludge on the inner wall of the centrifugal box (71), thereby squeezing and draining the excess water that is difficult to centrifuge out; S3: The rotating centrifugal box (71) drives the rotating ring (63) to rotate, and the rotating ring (63) is slidably connected to the movable shaft (65) through the annular corrugated groove (64), and the movable rod (61) and the housing (1) are slidably limited, so that the movable rod (61) can be driven to move back and forth, and the movable rod (61) drives the knocking block (62) to knock and vibrate the filter screen (72), so that the sludge adhered to the filter screen (72) is shaken off to the bottom inner wall of the centrifugal box (71); S4: The positioning shaft (54) contacts the inner wall of the bottom of the centrifugal box (71) through the scraper (13), thereby cleaning the inner wall of the bottom of the rotating centrifugal box (71) and introducing the sludge into the collecting box (10) through the opening at the bottom of the centrifugal box (71). The sludge in the collecting box (10) is heated by the electric heating plate (14), thereby baking and drying the sludge, so as to facilitate resource utilization in the later stage.
