Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and more specifically to an air compressor capable of recovering waste heat. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. When the air compressor is working, its hydraulic oil needs to be cooled down, and the hydraulic oil has a lot of heat. When cooling, a heat exchanger is usually used for heat exchange. The heat after heat exchange can be used to heat water, and then the waste heat can be recycled.

[0003] Existing water for heat exchange flows directly into the water inlet pipe of the heat exchanger. Since the water contains impurities, these impurities will adhere to the pipes of the heat exchanger. Over time, the increasing number of impurities in the pipes will lead to pipe blockage. In addition, the impurities attached to the pipes will isolate heat and affect the heat exchange efficiency. Utility Model Content

[0009] Technical effects and advantages of the utility model:

[0010] 1. During normal use of the air compressor that can recover waste heat, valves 2 and 4 are opened, and external water flows into the filter cover through the bent pipe. At this time, the filter cover can filter impurities in the external water to prevent impurities in the water from entering the heat exchanger and causing blockage of the heat exchanger.

At this time, the rotating column drives the filter cover to rotate, so that the water sprayed from the T-tube can cover the entire filter cover, thereby ensuring the cleanliness of the filter cover.
