[0031] Working process: When an exhaust purification device in a processing workshop is running, the fan in the device starts, driving the fan blades 5 to generate negative pressure, and extracting the polluted air in the workshop into the exhaust system. The extracted air flows along the air inlet duct 3 to the filtration system 6. The air first passes through the primary filter 63 to remove larger particles, and passes through the medium-efficiency filter 64 to remove smaller particles and other impurities. The air then passes through the high-efficiency filter 65 to further capture tiny particles and harmful gases to ensure that the discharged air meets safety standards. Finally, the purified air enters the circulation system along the outlet duct 2. During the operation of the equipment, the vibration system 67 will automatically start at regular intervals. When starting, the motor 677 drives the second pulley 676. At the same time, the second pulley 676 drives the first pulley 674 through the belt 675.
