[0002] A shot blasting machine is a mechanical device that sprays metal particles or abrasives at high speed. It is mainly used to clean, improve surface quality or increase material adhesion. During the shot blasting operation, a large number of fine particles will be generated during the collision and friction between the material and the processed object. These particles will be suspended in the air to form dust. Therefore, when using a shot blasting machine, an external wet dust removal equipment is required to recover the dust.

[0003] When the wet dust removal equipment is working, it is necessary to first use a pipe to connect the processing chamber of the shot blasting machine with the air inlet pipe of the equipment, and then use the fan inside the equipment to suck the dust into the filter chamber. Since the suction force of the fan inside the dust removal equipment is relatively large, if the connection between the pipe and the air inlet pipe is unstable during operation, it may become loose and cause dust leakage. In addition, the connection between the pipe and the air inlet pipe will generate a lot of noise, resulting in reduced practicality and environmental protection of the dust recovery device.
