[0002] Environmental protection, the full name of which is environmental protection, refers to the general term for various actions taken by humans to solve real or potential environmental problems, coordinate the relationship between humans and the environment, and ensure the sustainable development of the economy and society. Its methods and means include engineering technology, administrative management, legal, economic, publicity and education, etc. Electric welding is prone to produce welding smoke when processing workpieces. The welding smoke contains acetaldehyde, rosin acid, sulfide, etc. These pollutants float in the air and invade the liver, lungs, cardiovascular system and blood through the respiratory tract. These harmful substances seriously devour human health and lead to the emergence of many occupational diseases.

[0003] Most of the existing welding smoke treatment and purification devices rely on filter screens or activated carbon plates to purify the flue gas, but the filtering effect is not good. There may still be some small particles in the flue gas that cannot be removed. Therefore, we urgently need to provide a welding smoke treatment and purification device.

[0012] Preferably, valves are installed at the upper ends of the plurality of discharge pipes.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The air inside the purification tank is extracted by setting a vacuum pump and an exhaust pipe to form a vacuum negative pressure inside the purification tank. At this time, the smoke pipe will generate suction to absorb the welding smoke into the inner side of the filter cylinder inside the purification tank. The servo motor drives the rotating shaft to drive the impeller to rotate, so that the smoke inside the filter cylinder generates centrifugal force to rotate continuously, thereby throwing the particulate impurities contained in the smoke to the inner wall of the filter cylinder, so that the device can remove harmful substances in the welding smoke with high efficiency and better purification effect, ensuring that the environment of the construction site is not polluted;
