The oil-water separation unit includes a main cone disc and a plurality of sub cone discs located at the bottom of the main cone disc.

In the oil-water separation operation, the waste water containing grease can be continuously injected from the main oil-water injection port and directed to an oil-water separation space in the inner cylinder. And when the drive shaft of the rotating unit is driven by power and drives the inner cylinder and the oil-water separation unit to rotate, the grease-containing waste water located in the oil-water separation space will be acted on by centrifugal force, so that the grease with a lighter specific gravity will gather closer to the rotating unit , The waste water with heavier specific gravity will converge towards an inner ring wall of the inner cylinder. Then, the grease and wastewater that have shown phase separation will be pushed by the grease-containing wastewater that is continuously replenished from the oil-water injection pipe, and the wastewater at the periphery will naturally flow through the main cone. The top surface is finally discharged through the water outlet with the opening direction downward.

The grease located in the inner circumference will naturally pass downward through the oil spill hole, and finally be discharged through the oil drain channel.

Although this separated oil-water separator can achieve the intended purpose. However, due to the small diameter of the overflow hole provided on the bottom wall of an inner cylinder, the efficiency of oil drainage will be reduced.
