At the same time, the residue blocked on the outer wall of the filter screen 17 is cleaned through the drain pipe 19. The forward and reverse rotation of 10 drives the drain pipe 19 to rotate inside the filter chamber 1, so as to achieve comprehensive cleaning of the outer wall of the filter screen 17. At the same time, when too much slag is accumulated at the bottom of the filter chamber 1, the accumulated slag can be cleaned through the discharge port 21, and the biogas slurry entering the mixing chamber 3 is processed in the next step. At the same time, the card plate 7 can be rotated to disengage the card plate 7 from the limit shaft 6 to open the card plate 7 to open the bottom plate 5 from the bottom end of the mixing chamber 3, so that the staff can clean the inside of the mixing chamber 3.
