Further, the gate includes a gate body and two side plates, and the two side plates are fixed on the side walls of the water outlet tank.

Further, the water outlet side of the flashboard is also provided with a guide plate, and the guide plate is provided with several guide holes.

Further, the deflector and the shutter form an angle of 45 degrees.

Compared with the prior art, the utility model has the advantages of:

1. By adopting the technical solution of the present utility model, the gate plate is set in the water outlet tank, which can increase the water level of the water outlet tank, make the water collection hole of the water collection tank be located below the liquid level, and avoid the inclination of the water collection tank caused by the settlement of the clarifier foundation. Bias flow, so that the resistance of the water collecting holes of the sump is equal, and then ensure that the flow velocity of each part of the clarifier is equal, and the clarifier has a normal output;

2. Adopting the further technical solution of the utility model, a deflector is arranged on the water outlet side of the gate, which can avoid the water flow from scouring the water outlet tank and improve the life of the clarification tank.
