The waste flowing into the guide pipe 11 is:
The two spiral portions 11a and 11b, which are curved in a spiral, flow down while rotating. In particular, since the annular portions 11a and 11b are curved in the vertical direction, a strong swirling flow is generated. The flow inertia, which is combined with the pressurizing action, occurs, and the waste flows down vigorously and is discharged into the storage tank 10.

The suction valve 9, the discharge valve 14, and the gate valve 18
The opening / closing operation, the supply of pressurized air to the ventilation section 17 and the washing water tank 22, and the operation of the negative pressure means 19 are automatically controlled by an electric control circuit including an electromagnetic valve.
