This utility model discloses a sludge scraping and slag removal device for a black film biogas digester, belonging to the field of biogas digester technology. It includes: a sludge discharge pipeline system located inside the black film digester; the sludge discharge pipeline system includes a main sludge discharge pipe, with sludge discharge branch pipes connected to both sides of the main sludge discharge pipe, and a fixed cylinder installed at the end of each branch pipe away from the main sludge discharge pipe. This utility model uses a pump installed on the sludge discharge pipeline system to generate suction on the sludge, causing the sludge to be discharged upwards from the bottom of the digester along the branch pipes and the main sludge discharge pipe. When the sludge passes through the inside of the fixed cylinder, it pushes the impeller plate on the connecting shaft, which in turn drives the mounting base and flexible scraper rod to rotate. This facilitates light scraping of the sludge around the inlet of the branch pipe, loosening the accumulated sludge and making it easier for the sludge to collapse under gravity. Simultaneously, a backwashing system uses water pressure to flush the sludge at the bottom of the digester, reducing the integrity of the sludge, increasing its fluidity in the wastewater, and making it easier to discharge.
