Problems solved by technology

[0002] A lot of dust is generated during many industrial productions, which is harmful to health and needs to be removed to the outside as much as possible. The exhaust capacity of current industrial exhaust fans is usually more effective, and a lot of dust is easy to accumulate on the blades, which affects the exhaust. Effect
