Description

Technical Field

[0001] The utility model relates to the technical field of impeller welding, in particular to a compressor impeller welding processing device. Background Art

[0002] The impeller is composed of a hub and blades. The wind passes through the impeller, driving the impeller to rotate, thereby driving the generator to rotate and converting wind energy into electrical energy. The impeller is made by welding. However, when welding the impeller, because of the high-temperature arc, the end of the electrode and its base material are melted accordingly, and the surface of the molten liquid violently sprays high-temperature and high-pressure steam generated by the flux-coated welding core and spreads around to form smoke. The most toxic substances in the smoke are MnO2 (accounting for about 7.5% of the welding smoke) and Fe2O3 (accounting for nearly 50% of the welding smoke), S iO2 (accounting for nearly 20% in welding fume), etc., can cause manganese poisoning and silicosis in welders; and when the existing impeller is welded, the fume will escape into the surrounding air, causing the workers to inhale harmful fume into their bodies. Long-term inhalation of welding fume by workers can cause dizziness, headache, cough, chest tightness and shortness of breath, etc., causing fibrous lesions of lung tissue, namely welder's pneumoconiosis, and is often accompanied by complications such as manganese poisoning, fluorine poisoning and metal fume fever, which is not conducive to the health of workers.
