Description

Technical Field

[0001] The utility model relates to the technical field of screw air compressors, in particular to an air intake filter device for a screw air compressor. Background Art

[0002] The screw air compressor adopts a pre-packaged configuration. The screw air compressor only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work. The screw air compressor has consistently provided high-quality compressed air for all walks of life with its advantages of high performance, high efficiency, maintenance-free, and high reliability. When the screw air compressor is in use, an air intake filter device is required to filter dust and impurities in the atmosphere, so that clean air can reach the compressor body through the air intake control valve and be fully mixed with the cooling lubricating oil for compression. The oil-containing gas is discharged after compression. After a series of treatments, compressed air with less oil content is obtained through the oil and gas filter.

[0003] The air intake filter devices of screw air compressors currently in use are mostly composed of filter plates arranged at the air inlet. The air intake filter devices of this structure are prone to absorb a lot of dust on the surface when used for a long time. If the filter plates are not cleaned in time, it is easy to cause the air intake of the screw air compressor to be blocked. When the filter plates are blocked, the filtering effect will also decrease, so that impurities in the atmosphere can enter the interior of the screw air compressor, causing blockage of the screw air compressor and damage to the screw rotor, affecting the use of the screw air compressor.
