By controlling the hydraulic rod 6, the cleaning brush plate 21 is brought into contact with the surface of the rotating conveyor belt 16, so that the residual sludge on the surface of the conveyor belt 16 can be cleaned. There is no need for manual cleaning by staff. The cleaned sludge can be collected through the filter screen 20, and subsequently, the filter screen 20 can be taken out and cleaned by opening the sealing door 4.
