The filtered clear water flows out of the through hole and is collected into a clear water collecting tank through a high-pressure hose, and the clear water can be directly discharged outside. After the mud making is finished, the hydraulic pressing device releases the pressure, and the pressing plate returns to the initial position. The automatic plate pulling device sequentially pulls the movable filter plates apart, and the coal cakes between the filter plates are collected and transported by the belt conveyor. Meanwhile, the filter cloth cleaning device is controlled by a limit switch to synchronously operate with the automatic pulling plate device, the high-pressure gas-liquid hose and the high-pressure washing nozzle are slidably mounted above the movable filter plate, when the pulling plate is pulled open, the filter cloth cleaning device operates to the plate frame position to wash the filter cloth by introducing high-pressure water vapor, the water volume of the high-pressure water vapor is small, the high-pressure water vapor can be conveyed out along with a coal cake, and a second filter plate is pulled open after cleaning until the cleaning is finished. And after cleaning, the hydraulic pressing device presses the plate frame again to start the next working cycle.

The utility model has the advantages that: the water production deslimer is used for separating solid and liquid. Compared with other solid-liquid separation equipment, the mud cake filtered by the water-making mud remover has higher solid content and excellent separation effect, and the quality of the filtered clear water is higher. The device gives consideration to the synchronous proceeding of water making and mud removing, assists water making, can reduce the concentration of raw water, lightens the pressure of water making of the main system, operates when the main system does not influence the sewage treatment, improves the water treatment efficiency, and has the functions of dredging and coal-water separation.
