[0037] The working principle of the present utility model is as follows: When in use, people push the device into the processing workshop through the trolley frame 24, and then people control the operation of the negative suction fan 13 through the PLC controller 23, so that a negative pressure is generated in the air collecting hood 11. Thus, the air around the air collecting hood 11 passes through the protective net 21 that can block larger foreign objects and enters the air collecting hood 11, and then enters the purification box 15 through the second conduit 20. The dust in the air can be filtered by the dust filter plate 18, and the harmful substances contained in the harmful gases in the air are adsorbed by the activated carbon filter plate 17.
