Oil entering from the liquid inlet enters the centrifugal barrel through the hole in the middle of the separation layer.

Furthermore, the top of the centrifugal barrel is open, and the side wall of the centrifugal barrel is provided with a plurality of through holes. The oil in the barrel is thrown out of the barrel from the through holes by the through holes, and the oil-water mixture outside the centrifugal barrel can be driven to rotate.

Further, the separation layer is made of a rubber material.

Furthermore, the inner wall of the shell is provided with a seal installation clamping ring, and the separation layer is detachably arranged in the seal installation clamping ring. The separate layer can be dismantled, is convenient for wash and maintain casing inside at the later stage.

The utility model discloses the beneficial effect who gains is: a centrifugal motor is adopted to drive a centrifugal barrel to carry out primary separation on the oil-water mixture, and a membrane separator and an oil absorption assembly are used for further carrying out oil-water separation on the oil-water mixture, so that the discharged water does not contain oil, the discharge standard is reached, the procedures for further treating the wastewater are reduced, and the cost is reduced; the shell cover, the separating layer and the V-shaped separating plate can be detached to clean and maintain the shell body, the membrane separator and the oil absorption assembly can be cleaned or replaced, and the service time of the oil-water separator is prolonged.
