Packing paper production pulp settling tank with cleaning structure

The utility model discloses a pulp settling tank with a cleaning structure for packaging paper production, which comprises a settling tank, a pulp outlet pipe and a box door, and one end of the settling tank is fixedly connected with a motor. Through cooperative use of the screw nut cleaning plate, the air bag, the air collecting pipe, the air spraying pipe and the extrusion block, a worker drives the ball screw to rotate by turning on the motor, so that the screw nut cleaning plate cleans sundries accumulated in the sedimentation tank, and meanwhile, in the moving process of the screw nut cleaning plate, the cleaning efficiency is greatly improved. When the screw rod nut cleaning plate is cleaned, the extrusion block extrudes the air bag, at the moment, air stored in the air bag enters the air spraying pipe through the air collecting pipe, so that the air can be sprayed out from the smaller air spraying pipe after being compressed, sundries accumulated on the surface of the screw rod nut cleaning plate are c
