Solid-liquid separation device for centrifugal machine

The utility model relates to a solid-liquid separation device for a centrifugal machine, which comprises a purified water storage tank, a disc centrifugal machine and a booster pump, and a water outlet pipeline of the booster pump is divided into a rotary drum sealing water pipeline and a deslagging opening water pipeline. A first electromagnetic valve is installed on the rotary drum sealing water pipeline, a second electromagnetic valve and a third electromagnetic valve are sequentially installed on the deslagging opening water pipeline, the deslagging opening water pipeline is further connected with an air channel pipeline, and a compressed air source, a fourth electromagnetic valve and a quantitative piston are sequentially connected to the air channel pipeline. And the quantitative piston is connected with the water inlet end of the third electromagnetic valve. The device is matched with logic control, full-automatic quantitative deslagging control can be achieved, and the problem that control over the de
