Description
Technical Field
[0001] This utility model relates to the field of industrial dust removal equipment technology, and more specifically, to an adjustable rotary suction arm device. Background Technology
[0002] In the industrial production sector, dust pollution is a serious problem in places such as large component welding workshops and heavy machinery assembly plants. Taking large component welding workshops as an example, a large amount of dust with complex composition is generated during the welding process. This dust mainly contains metal oxides, such as iron oxide dust generated when welding carbon steel, and aluminum oxide dust generated when welding aluminum and aluminum alloys. In addition, there may be unburned carbon particles. If welding rods containing heavy metals such as lead and cadmium are used, the dust will also be mixed with corresponding heavy metal particles. Therefore, efficient dust removal equipment is required.
[0003] Existing decentralized dust collectors suffer from problems such as large coverage blind spots, difficulty in relocation, and high energy consumption, while overall workshop dust collection suffers from defects such as high duct resistance, low end-of-line collection efficiency, and inability to adapt to changes in workpiece position.
[0004] Therefore, we have made improvements to this by proposing an adjustable rotary suction arm device. Utility Model Content
