The other end of the connecting pipe enters the water seal tank. A discharge pipe is arranged on the top of the water seal tank. A fermentation liquid outlet pipe is arranged on one side of the lower part of the fermentation box.

[0006] Preferably, a screw rod is provided in the sedimentation box, the screw rod is connected to the motor, and the upper part of the screw rod is a bare rod design, the threaded position at the lower part of the screw rod is connected to the movable plate, the lower part of the movable plate is provided with a filter grille, the conveying channel is arranged close to the inner wall of the sedimentation box, the conveying channel is connected to the feed port, the upper part of the conveying channel is a blocked design, the lower end of the conveying channel is an open design, and the movable plate and the filter grille are provided with a notch for installing the conveying channel.

[0007] Preferably, the movable plate can move up and down in a vertical direction, and a plurality of filter ports are provided on the movable plate, the filter ports include an upper opening, a lower opening, an inclined channel, a cover plate, and a spring. The upper opening is connected to the lower opening via the inclined channel, and the upper opening and the lower opening are staggered.

A hinged cover plate is provided above the upper opening, and a spring mounted with screws is provided at the lower part of the cover plate, and the spring is connected to the inner wall of the upper opening.

[0008] Preferably, the water seal tank is filled with tap water, the connecting pipe extends below the tap water level, and the discharge pipe is located above the tap water level.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model has a reasonable design; the filter grille in the sedimentation box can intercept the debris, and the filter port on the movable plate can reduce the debris discharged with the liquid while ensuring the liquid is discharged. When the liquid needs to be discharged, the motor is used to drive the movable plate to move up, and the cover plate on the movable plate is pressed down to block the upper opening. With the upper part of the movable plate, the liquid enters the fermentation box through the inclined pipe. After the movable plate moves down, the liquid overflows to the upper part of the movable plate through the lower opening, the inclined channel and the upper opening. Under the blocking effect of the inclined channel, the debris entering the upper part of the movable plate is reduced; the fermentation box can ferment the sewage under anaerobic regulation; the water seal tank can absorb the cyanide in the tail gas produced by the fermentation, reducing the pungent smell; the liquid after fermentation in the fermentation box can be used for plant irrigation.
