Description

Technical Field

[0001] The invention relates to the field of air compressors, in particular to an oil separator of an air compressor. Background Art

[0002] The oil separator of an air compressor is a key component used to separate and remove oil mist and liquid oil from compressed air to provide clean compressed air. Oil separators are particularly important in lubricated air compressors because the compression process of these air compressors usually requires the use of lubricating oil to reduce friction, improve efficiency and extend equipment life. An air compressor, also known as an air compressor, is a device that compresses air by mechanical means. Its basic function is to compress low-pressure air or other gases into a high-pressure state for storage, transportation or direct use. Air compressors are widely used in multiple industries and fields.

[0003] However, most traditional air compressor oil separators use a single-layer filtration method to separate the oil and liquid in the gas, which results in a low filtering effect of the oil separator on the oil and liquid in the gas, and is unable to effectively remove fine oil mist and tiny impurities, resulting in the oil being discharged with the air, affecting the performance of downstream equipment.

[0004] Therefore, those skilled in the art provide an oil separator for an air compressor to solve the problems raised in the above background technology. Summary of the invention

[0026] (III) Beneficial effects

[0027] The present invention provides an oil separator for an air compressor, which has the following beneficial effects:

[0028] 1. The present invention provides an oil separator for an air compressor. Compared with the oil separators of most traditional air compressors, the oil separator of the air compressor is respectively provided with a first filtering mechanism, a second filtering mechanism and a third filtering mechanism. The third filtering mechanism extends the distance of gas circulation by a spiral guide plate, increases the contact area between the gas and the baffle, can effectively enhance the contact between the gas and the oil, enables the oil to be initially adsorbed when passing through the interception groove, and improves the effect of oil-gas separation. The metal mesh filter gap of the second filtering mechanism is smaller than the interception groove. Through the multi-layer metal mesh filter arrangement interception, the oil in the gas is adsorbed more finely, and then the oil in the gas is further separated. Finally, the synthetic fiber filter element arranged in the first filtering mechanism intercepts and adsorbs the gas more finely. By setting the first, second and third filtering mechanisms, multi-level and multi-stage filtration can be achieved. Each filtering stage can filter oil droplets of different sizes, improve the overall oil separation efficiency, and ensure that the residual oil in the gas is significantly reduced.

[0029] 2. The present invention provides an oil separator for an air compressor. Compared with most traditional oil separators of air compressors, the first filter mechanism and the second filter mechanism provided in the oil separator of the air compressor can be disassembled, cleaned or replaced. The detachable design makes it easier to clean and maintain each filter component, reduces maintenance time and labor intensity, improves operational convenience, and the structure that is easy to clean regularly can more effectively remove dirt and grease accumulated in the device, keep the filter in the best working condition, thereby ensuring the stability of filtering efficiency and performance, and reducing performance degradation caused by clogging.

[0030] 3. The present invention provides an oil separator for an air compressor. Compared with most traditional oil separators of air compressors, the metal mesh filter arranged in the second filtering mechanism of the oil separator of the air compressor can be disassembled and replaced. In an environment with a high oil and gas content, the number of filters can be increased to enhance the filtering effect, while in an environment with a low oil and gas content, the number of filters can be reduced to reduce airflow resistance. In this way, the device can adjust the number of metal mesh filters according to different working environments and usage requirements to meet specific filtering requirements, thereby improving the scope of application of the device.

The gas after preliminary filtration will enter the outer casing through the ventilation duct 8 and contact with multiple metal mesh filters 709, thereby being intercepted and adsorbed by the second layer. The oil flows into the oil drain groove 11 through the oil drain groove 707 and the oil drain pipe 10, and finally the remaining oil in the gas will be more finely intercepted and adsorbed by the synthetic fiber filter element 607, and finally the gas is discharged through the exhaust port 606.
