[0002] The dry treatment method for welding fume is to configure a purification system at the welding station to directly transport the welding fume to the purifier for treatment, and then discharge it indoors or outdoors to meet the emission standards. According to the method of capturing the fume, there are three types: door-type, blowing and suction-type, and airborne-type. This method does not produce secondary pollution, is easy to clean, and is suitable for various welding fume purification methods.

Sometimes it blocks the way of forklifts and mobile equipment in the workshop. Therefore, a purification device that can automatically wrap around the hose is needed to improve the hose wrapping efficiency. Utility Model Content
