Description

Oil-water separation kettle with graphene filter membrane

Technical Field

The utility model relates to the technical field of oil-water separation, in particular to an oil-water separation kettle of a graphene filter membrane.

Background Art

With the development of materials science, the application of graphene in life and industrial production has become increasingly widespread. According to its own characteristics, preparing it into a filter membrane of graphene composite material can play a good role in oil-water separation operations.

A Chinese patent document with publication number CN209630678U discloses an oil-water separation kettle based on a graphene filter membrane, comprising a kettle body vertically arranged on a base, a top cover arranged on the top of the kettle body, a feed port on the top cover connected to a feed pipe, and a discharge port arranged at the bottom of the kettle body; a bracket is arranged on the outside of the kettle body, a screw rod is vertically arranged at the central axis of the kettle body, the upper end of the screw rod passes through the top cover and is threadedly connected to the top cover, and the screw rod extends to the outside of the top cover, and the upper part of the screw rod is connected to the top plate of the bracket through a bearing;

Although the device can conveniently replace the filter membrane in the separation kettle, making the replacement process of the filter membrane very simple and easy, the inventor believes that only a graphene filter membrane is set in the kettle of the device, and the oil and water will contain some impurities. If the impurities are not filtered, the graphene filter membrane will easily accumulate on the membrane surface, which will eventually reduce the efficiency of the graphene filter membrane and require replacement in a short time, which not only increases the cost but also increases the manpower. To this end, we propose an oil-water separation kettle with a graphene filter membrane.
