A stirring paddle 12 is connected to the middle of the first stirring shaft 6, and a second stirring shaft 11 connected to the stirring paddle 12 through a second transmission part 10 in the middle of the first stirring shaft 6 is connected. In this embodiment, the first transmission part and the second transmission part are both bevel gear transmission devices. At least one feeding hole 2 is provided on the stirring chamber body 5, and a spiral pattern protrusion 17 is provided on the inner wall of the stirring chamber body 5, and the protrusion tip is upward. When the stirring chamber body rotates, the slurry inside the cavity near the inner wall of the cavity is transmitted upward along the thread.

The bottom of the stirring device shell 1 is a conical structure, and a discharge port 13 is provided at the bottom of the shell 1. The discharge port 13 is the lowest point of the shell bottom of the conical structure. The discharge port 13 is connected to a filter part 14, and the filter part 14 includes a fixedly arranged filter screen 18. A baffle 19 is rotatably arranged on the upper end of the filter screen 18, and a notch is provided on the baffle 19 for discharging the material.
