Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, and in particular relates to an air compressor inlet filter device. Background Technology

[0002] An air compressor is a mechanical device that converts the mechanical energy of a prime mover (usually an electric motor) into the pressure energy of a gas. It is a device that generates compressed air by directly changing the volume of the gas to increase the gas pressure. For example, a piston air compressor uses a crankshaft and connecting rod to drive a piston to move back and forth in a cylinder. When the volume of the upper part of the cylinder increases, air is drawn in, and when the volume decreases, air is discharged, thereby compressing the air.

[0003] Air compressors are mostly used in industrial plants, where the operating environment is relatively harsh. Generally, air compressors need to be placed in the corners of the factory where there is a lot of dust. Usually, a filter screen is installed at the air inlet. However, over a long period of use, a lot of dust will accumulate on the surface of the filter screen. In order to clean the dust on the filter screen in a timely manner, we propose an air compressor air inlet filter device that can quickly clean the dust and avoid filter screen clogging.
