Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, and more specifically, to a telescopic welding ventilation device. Background Art

[0002] A large amount of harmful smoke will be generated during welding operations. If the harmful gases are not discharged in time, the harmful gases generated during operation will continue to accumulate, which will increase the concentration of harmful gases. The long-term presence of harmful gases will cause damage to the bodies of workers working in the factory. Therefore, when the factory where the welding equipment is placed is in use, ventilation devices need to be installed to collect and purify the welding smoke and harmful gases inside the factory to achieve ventilation of the factory. The telescopic factory is different from the general fixed factory. It is a special factory that can be folded, telescopic and easily moved as needed.

[0003] The factory ventilation device in the prior art generally realizes ventilation and exhaust of harmful gases, smoke and other gases by combining multiple air intake fans installed on the walls around the factory and multiple exhaust fans installed on the top of the factory.
