Using turbid liquids with different densities of liquid and liquid, liquid and solid in a high-speed rotating drum, multi-components with different densities form a ring shape under the action of centrifugal force. The densest solid particles move outward and accumulate in the drum Peripheral wall, light phase liquid in the innermost layer. There are discs inside the drum, which divides the drum space into many thin layer separation spaces, which greatly reduces the settlement distance and improves and improves the separation effect. Any extreme particles between the two discs reach the inner surface of the disc and can be separated out. The separated oil is output by the light phase centripetal pump, the water is output by the heavy phase centripetal pump, and impurities are discharged from the impurity pump.
