Mud removal device for production of polyaluminum chloride

The utility model discloses a desilting device for polyaluminum chloride production, which comprises a desilting bin, a servo motor mounted at the top of the desilting bin and a closed bottom cover attached to the bottom end of the desilting bin, and is characterized in that a material ingress pipe is arranged at the top end of the desilting bin and positioned on the outer side of the servo motor; and a solution inlet is formed in one side of the material guide-in pipe, a base is fixed to the outer side of the bottom end of the desilting bin, a discharging hole is formed in the closed bottom cover, and a hole opening adjusting mechanism is arranged in the closed bottom cover and located on one side of the discharging hole. The stirring rod is driven by the servo motor to rotate, so that polyaluminum chloride and a solution gathered in the desilting bin generate centrifugal motion, the speed of separating sludge from the surface of the polyaluminum chloride is increased, the separation quality of the sludge is
