Description

An easy-to-remove gas filter device for a compressor

technical field

The invention relates to the technical field of compressors, in particular to an easily removable gas filter device for compressors.

Background technique

During the conveying process of compressed gas, in order to prevent the unqualified air quality caused by the liquid water and other impurities contained in the gas conveying, and then lead to various failures caused by this, the gas pipeline system is usually provided with gas. The filter separates the liquid water and various impurities contained in the gas through the gas filter, and then discharges it through the drain valve to ensure the safe operation of the equipment. Under normal circumstances, the gas filter equipped with the compressor adopts a down-rotating disassembly structure or a flange-type lower disassembly structure. In order to meet the application of the above two disassembly structures under high flow or high pressure conditions, the volume and wall thickness of the filter must be increased for conventional gas filters, and the gas pipeline must be disassembled to replace the filter element during disassembly and assembly. It is easy to cause the risk of gas leakage due to the disassembly and assembly of flammable and explosive gas pipelines. The disassembly and assembly are very difficult and work intensity is very large, which brings great difficulties to on-site maintenance and replacement of filter elements.
