Abstract

PURPOSE: To keep the safety of workers by enabling scum or sedimental sand to be discharged continuously by operating manually a scum suction float and a sedimental sand suction device from the outside of the digestion tank in the cleaning of the tank.
CONSTITUTION: The scum F is continuously sucked up by causing the suction float 12 to come near a scum floating position while operating an exhauster with a displacement of more than 20m3/min, and after the sedimental sand suction device 25 connected to the suction hose 9 instead of the suction float 12 goes down to the sedimental sand, the sedimental sand is continuously sucked up by operating the exhauster 7 while sending air into the air supply hose 22 and at the same time by causing the sedimental sand suction device to come near the sand-deposit position.
