[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up cleaning and discharge components, when the gate is opened and water is introduced, the water flows into the inlet chamber, is filtered by the grate, and then enters the sludge discharge chamber. The first motor drives the scraper to brush the surface of the grate through the screw, preventing debris from adhering to the surface of the grate. The scraper is brushed back and forth by the forward and reverse rotation of the first motor, pushing the floating objects on the surface of the grate into the discharge chute. The conveyor belt driven by the second motor sends the debris out of the inlet pool, thus achieving convenient cleaning.

The water inlet chamber and the sludge discharge chamber are set up vertically, with the sludge discharge chamber being deeper than the water inlet chamber. This slows down the water flow inside the sludge discharge chamber, increasing the sedimentation time of the sludge in the water. In addition, there is an inclined plate in the sludge discharge chamber. The principle of inclined plate sedimentation improves the sedimentation efficiency. While the sludge is settling, the third motor drives the scraper on the connecting shaft to collect the sludge at the bottom of the sludge discharge chamber into the sludge guide pipe. When it has accumulated to a certain extent, it is discharged through the sludge discharge valve. Attached Figure Description
