Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel mesh cutting, in particular to an exhaust gas collecting device for stainless steel mesh cutting. Background Art

[0002] When cutting stainless steel mesh, high-speed cutting and friction can generate fine dust and harmful gases, which not only pollute the environment but can also harm workers' health. Stainless steel mesh waste gas collection equipment is a device specifically designed to capture and treat waste gas and dust generated during industrial production.

[0003] The patent with announcement number CN219804400U discloses a waste gas collection and purification device, which drives a rotating rod through a driving motor, and the rotating rod drives a stirring rod and an L-shaped connecting frame. When the stirring rod rotates, it stirs the water source in the purification barrel, so that the waste gas flowing into the purification barrel can fully contact with the water source to purify the waste gas. When the L-shaped connecting frame rotates, it drives the rotating ring, and the mounting frame drives the spray head to rotate, and then the waste gas after the initial purification can be secondary purified by the spray head. The rotation and spraying of the spray head can make the water mist fully contact with the waste gas, thereby improving the purification effect of the waste gas and reducing the pollution caused by the waste gas to the air. However, when the waste gas collection device collects the waste gas generated by cutting the stainless steel mesh, the large particles of dust contained in the waste gas will cause blockage to the gas collecting pipe, thereby reducing the collection efficiency of the waste gas.
