Welding is not limited to steel pipes, but also involves the processing of a variety of building materials such as steel bars, steel plates, and steel structures. Welding ensures the stability and safety of the structure because it provides a durable and reliable connection. Welding is not only used in new construction projects, but also for repairing and reinforcing existing structures.

[0003] The waste gas generated during welding usually contains a variety of harmful substances, which pose a serious threat to the health of welders. In addition, these waste gases will pollute the environment and affect the air quality. Therefore, the waste gas generated during welding needs to be managed through an effective waste gas recovery device to protect the health of workers and environmental safety. A welding waste gas purification device that is convenient for replacing filter elements in the prior art is somewhat difficult and time-consuming to maintain and replace the filter material, and the operator is very passive in using it. Therefore, it is necessary to develop a welding waste gas purification device that is convenient for replacing filter elements to solve the above technical problems. Utility Model Content

The material of the connecting pipe 2 can be set as a metal bellows, and the dust hood 1 can be adjusted as needed.

[0026] like Figures 1-6As shown, as a preferred mode of the above embodiment, the shell 7 is set to be a circular ring body, and the shell 7 includes an outer ring body 701 and an inner ring 702, and both the outer ring body 701 and the inner ring 702 are provided with openings 705; the shell 7 is rotatably arranged in the treatment box 4, a connecting plate 704 is arranged in the inner ring 702, and a toggle block 8 for rotating the shell 7 is arranged at the upper end of the shell 7; a bearing is arranged at the bottom end of the shell 7. A limit plate 19 is arranged in the shell 7 to divide the shell 7 into four cavities; the first group of activated carbon 18 and the second group of activated carbon 20 are arranged opposite to each other in the four cavities.

[0027] The design of the housing 7 and the toggle block 8 enables the activated carbon adsorption assembly to rotate, so that the first group of activated carbon 18 and the second group of activated carbon 20 set in opposite activities can be used more evenly, extending their service life and facilitating replacement and maintenance.
