Description

Technical Field

[0001] The utility model relates to the technical field of automatic drainage devices, in particular to a compressed air automatic drainer. Background Art

[0002] During the production process of an enterprise, production equipment needs to use a large amount of dry compressed air. After the air compressor compresses the air, it needs to be dried before being transported to various equipment for use. Before drying, the compressed air contains a large amount of moisture, impurities, oil, etc., which will clog and damage the filter of the drying equipment.

[0003] At present, the filter part of the drying equipment is discharged directly or uses a float drainage system. Direct discharge causes a huge waste of compressed air, and the float drainage system is easily blocked and difficult to clean.

[0004] For this reason, we proposed the compressed air automatic drain. Utility Model Content
