[0021] The bottom end of the container 1 is a cone that contracts downwards, a sewage inlet is provided at the top of the container 1, and a sewage outlet is provided at one side of the bottom of the container 1;

[0022] The screw 3 is coaxially arranged in the containing tank 1, the bottom of the screw 3 is fixedly connected to the bottom of the containing tank 1, the stirring shaft 2 is vertically arranged, the bottom end of the stirring shaft 2 penetrates the top of the containing tank 1 and extends into the containing tank 1 and is rotatably connected to the screw 3, and the driving assembly is drivingly connected to the top end of the stirring shaft 2;

[0023] The screw 3 is threadedly connected to the middle part of the sealing disk 4. The sealing disk 4 is a conical disk that matches the bottom of the containing tank 1. The connecting plate 6 is horizontally arranged in the containing tank 1. The stirring shaft 2 is fixedly connected to the middle part of the connecting plate 6. The connecting plate 6 and the sealing disk 4 are connected by a telescopic rod 5.

[0024] When the present invention is used, the sewage inlet, the pump and the suction joint are connected in sequence through the pipeline, and the driving component is first driven to drive the stirring shaft 2 to rotate, thereby driving the connecting plate 6 to rotate, and the connecting plate 6 rotates to drive the sealing disk 4 to rotate so that the sealing disk 4 descends to seal the bottom of the containing tank 1, and then the driving component is stopped to stop the stirring shaft 2, and then the pump is operated to make the sewage right suction joint and the sewage inlet enter the containing tank 1; when the sewage in the containing tank 1 needs to be discharged, the driving component drives the stirring shaft 2 to rotate in the opposite direction, thereby driving the connecting plate 6 to rotate in the opposite direction, and the connecting plate 6 rotates in the opposite direction to drive the sealing disk 4 to rotate in the opposite direction so that the sealing disk 4 rises, and the sewage is discharged from the gap between the sealing disk 4 and the containing tank 1 and the sewage outlet.

[0025] Specifically, the driving component is a motor, and the output shaft of the motor is fixedly connected to the top end of the stirring shaft 2.
