Description

A cooling air knife Technical Field

[0001] This utility model relates to the field of cooling air knife technology, and in particular to a cooling air knife. Background Technology

[0002] In industrial production, many processes require cooling of products or equipment to ensure product quality and normal equipment operation. Traditional cooling methods mainly include natural cooling and water cooling. Natural cooling is slow and cannot meet the needs of rapid cooling; while water cooling is fast, it suffers from water waste, equipment corrosion, and subsequent wastewater treatment problems. Cooling air knives are a new type of cooling device that achieves rapid cooling through the jetting of high-pressure air. Their working principle involves using a high-pressure centrifugal fan or vortex fan to compress air, which is then ejected at high speed through the slits or nozzles of the air knife, forming a uniform airflow that blows across the surface of the object, carrying away heat and thus achieving a cooling effect.

[0003] However, most existing cooling air knives are fixed in installation, and their installation height is difficult to adjust during use, making it difficult to flexibly adjust according to different cooling needs. Therefore, this utility model proposes a cooling air knife to solve the above problems. Summary of the Invention

The bottom of the top plate has several threaded holes evenly distributed, and the threaded holes correspond one-to-one with the positioning screws. The top plate and the chassis are fixed by screwing the positioning screws into the threaded holes.

[0010] Furthermore, a positioning ring is fixedly installed on the top of the chassis, and a sealing cover is fixedly installed inside the positioning ring. The sealing cover is fixed to the bottom of the chassis and is sealed and installed in the second hole.
