Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and in particular to a waste heat recovery structure for air compressors. Background Art

[0002] An air compressor is a machine that mechanically compresses a large amount of air into a confined space, increasing the pressure and density of the air for easy storage and use. It is widely used in various industrial fields such as manufacturing, construction, food processing, etc.

[0003] A Chinese patent discloses a waste heat recovery structure for an air compressor (publication number: CN220356137U). The waste heat recovery structure for an air compressor drives the rotating rod, the scraper and the reciprocating screw to rotate after the motor is started. The reciprocating screw drives the scraper ring to move up and down. The scraper and the scraper ring scrape off the scale and impurities attached to the inner wall of the waste heat recovery box. The scale and impurities can be discharged from the waste heat recovery box through the drain valve. However, the device still has the following problems:

[0004] After the water used to absorb waste heat has been exposed to high temperature, the calcium sulfate that is slightly soluble in water will precipitate due to the evaporation of water and form water scale. The scale formed after the water scale continues to increase will not only adhere to the inner wall of the waste heat recovery box, but also adhere to the oil pipeline, thereby affecting the heat conduction between the oil pipeline and water. For this reason, an air compressor waste heat recovery structure is proposed to solve the above problems. Utility Model Content
