Description

technical field [0001] The invention relates to the technical field of explosion-proof fans, in particular to an explosion-proof fan that can effectively reduce noise. Background technique [0002] Explosion-proof fans are widely used in construction and mining industries. Their main functions are ventilation, dust removal and cooling. The motor in explosion-proof fans is a device that can be used in flammable and explosive places. It will not generate sparks during operation. Explosion-proof fans During operation, noise will be generated; the existing explosion-proof fan cannot handle the noise better during use, which will cause noise pollution to the surrounding environment when it is in use, seriously affecting people's normal life, and then cannot be replaced. Good to meet people's needs. [0003] To sum up, how to make the explosion-proof fan achieve a better noise reduction effect is a technical problem that needs to be solved urgently. Contents of the invention ...
