A rotating connection is made. A motor is fixedly connected to the bottom of the treatment tank 1. The output end of the motor is fixedly connected to the stirring rod 7. A long rod 11 is provided inside the filter cake box 4. A connecting structure is provided between the long rod 11 and the stirring rod 7. The connecting structure includes a rotating block 6.

[0024] Specifically, the motor is started. The specific motor model is not limited, but depends on the compatible equipment. The motor output drives the stirring rod 7 to rotate. Since the connecting block 9 on the stirring rod 7 is located inside one of the connecting grooves 10, the rotation of the stirring rod 7 causes the first rotating block 6 to rotate. The first rotating block 6 drives the connecting block 9 on the long rod 11 to rotate through the other connecting groove 10. Therefore, the long rod 11 drives the second rotating block 13 to rotate on the L-shaped seat 14.

[0026] Specifically, the L-shaped limiting rod 15 is pulled away from the rotating block 13. The L-shaped limiting rod 15 moves out of one of the limiting grooves 110, raising the long rod 11. The connecting block 9 on the long rod 11 moves away from the other connecting groove 10. The two T-shaped brushes 12 can be moved out of the filter cake box 4 through the long rod 11.
