[0003] In the patent with the publication number CN 208054926 U, a sodium fluoride slurry separation device is disclosed, which includes a tank body. The lower end inside the tank body is of an arc structure. A motor is fixedly installed on the top surface of the tank body. A through hole is opened on the top surface of the tank body, and a bearing is arranged in the through hole. The outer ring of the bearing is fixedly connected with the inner wall of the through hole, and a vertical stirring rod is fixedly installed on the inner ring of the bearing. The upper end of the stirring rod is fixedly connected with the output shaft of the motor. The lower end of the stirring rod is located at the lower end inside the tank body. Several stirring paddles are fixedly installed on the outer ring of the stirring rod. An arc-shaped stirring head is fixedly installed at the lower end of the stirring rod.
