Description

Technical Field

[0001] The utility model relates to an oil mist separation device for an air compressor, belonging to the technical field of oil mist separation equipment for air compressors. Background Art

[0002] An air compressor is a device that compresses air and is widely used in many industries. During operation, the lubricating oil is pressurized by an oil pump and sent to various levels of bearings and gears. This process will generate a large amount of oil mist. In order to keep the oil tank in a slightly negative pressure state, the oil in the oil mist needs to be separated and discharged.

[0003] The fan of the oil mist separator sucks the oil mist out of the oil tank. Part of the oil in the oil mist precipitates in this process and flows back to the oil tank through the pipeline. The remaining oil in the oil mist is blocked and recovered when passing through the filter element at the top of the separation device. After the filter element has been working for a period of time, oil droplets will appear on the surface of the filter element, causing waste of lubricating oil and polluting the environment. Utility Model Content

[0004] The utility model aims to provide an oil mist separation device for an air compressor, which can recover oil droplets on the outer surface of a filter element during operation of the oil mist separator, thereby avoiding waste of lubricating oil and environmental pollution, and solving the problems existing in the background technology.

[0005] The technical solution of the utility model is:

[0006] An oil mist separation device for an air compressor comprises a filter element, a fan, a smoke exhaust pipe, an oil tank, an oil return pipe A, an oil return pipe B and an oil tank, wherein the filter element is arranged in the oil tank, and the fan outlet is connected to the filter element; the oil tank is located below the fan, the upper end of the smoke exhaust pipe is connected to the fan inlet, and the lower end of the smoke exhaust pipe is connected to the oil tank; the lower end of the oil return pipe A is connected to the oil tank, and the upper end of the oil return pipe A is connected to the oil tank; the lower end of the oil return pipe B is connected to the oil tank, and the upper end of the oil return pipe B is connected to the fan.

[0007] The smoke exhaust pipe is led out from the top of the oil tank and connected to the fan inlet; the oil return pipe A is led out from the bottom of the oil tank and connected to the bottom of the oil tank; the oil return pipe B is led out from the bottom of the oil tank and connected to the bottom of the fan.

[0008] The oil groove is arranged along the circumference of the filter element.

[0009] The oil groove is arranged in a circle along the circumferential direction of the bottom of the filter element.

[0010] The utility model has the beneficial effect that oil droplets on the outer surface of the filter element can be recovered during the operation of the oil mist separator, thereby avoiding waste of lubricating oil and environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS
