The valve 8 is opened, and the exhaust gas in the welding room 1 enters the heat exchange pipe 6 through the air transmission pipe 7. Since the water tank 4 contains cooling water, heat transfer occurs when the exhaust gas enters the heat exchange pipe 6. The heat carried by the exhaust gas is absorbed by the cooling water in the water tank 4, which reduces the temperature of the exhaust gas and avoids a sudden increase in the working environment temperature. The heat exchange pipe 6 is spirally distributed inside the water tank 4, which prolongs the time that the exhaust gas stays in the water tank 4, thereby effectively absorbing the heat carried by the exhaust gas;
[0025] The purification box 9 is arranged on the right side of the water tank 4, and a dust filter plate 10 is installed inside the purification box 9, and first limiting concave plates 11 are arranged on the left and right sides of the dust filter plate 10, and a dust collecting box 21 is arranged below the dust filter plate 10, the first limiting concave plate 11 is fixedly installed on the inner wall of the purification box 9, and the dust filter plate 10 is slidably connected to the inside of the purification box 9 through the first limiting concave plate 11, and the exhaust gas passes through the heat exchange pipe 6 to enter the purification box 9 and contact the dust filter plate 10, and the particulate impurities carried in the exhaust gas are intercepted by the dust filter plate 10 and fall into the dust collecting box 21, and an activated carbon filter plate 17 is arranged above the dust filter plate 10 in parallel, and second limiting concave plates 18 are arranged on the left and right sides of the activated carbon filter plate 17, an exhaust pump 19 is opened in the middle of the top of the purification box 9, and a controller 20 is installed on the right side of the purification box 9, the second limiting concave plate 18 is fixedly installed on the inner wall of the purification box 9, and the activated carbon filter plate 17 passes The second limiting concave plate 18 is slidably connected to the inside of the purification box 9, and the exhaust gas with particulate impurities removed passes through the dust filter plate 10 to reach the activated carbon filter plate 17. The odor in the exhaust gas is adsorbed by the activated carbon filter plate 17, and the purified exhaust gas is discharged from the purification box 9 through the exhaust pump 19, which realizes the ventilation inside the welding room 1 and can prevent the exhaust gas discharged from the welding room 1 from polluting the working environment. A cross bar 12 is arranged between the dust filter plate 10 and the activated carbon filter plate 17, and a rubber plate 13 is fixedly installed on the outer side of the cross bar 12. The right end of the cross bar 12 passes through the right side surface of the purification box 9 through a bearing and is connected to a rotating motor 14. By starting the rotating motor 14, the cross bar 12 and the rubber plate 13 are rotated. During the rotation of the rubber plate 13, it continuously collides with the dust filter plate 10, thereby continuously beating the dust filter plate 10, which is conducive to shaking off the particulate impurities on the surface of the dust filter plate 10 and reducing the probability of clogging of the dust filter plate 10.
[0026] Three cross bars 12 are provided, and gears 15 are installed on the outer side of the right ends of the three cross bars 12, and the outer side of the gear 15 is meshed with a chain 16.

[0027] Working principle: When in use, outside air is injected into the welding room 1 through the air pump 2 and the air inlet pipe 3, and the valve 8 is opened. The exhaust gas in the welding room 1 enters the heat exchange pipe 6 through the air transmission pipe 7. Since the water tank 4 contains cooling water, heat transfer occurs when the exhaust gas enters the heat exchange pipe 6. The heat carried by the exhaust gas is absorbed by the cooling water in the water tank 4, which reduces the temperature of the exhaust gas. The exhaust gas passes through the heat exchange pipe 6 and enters the purification box 9 and contacts the dust filter plate 10. The particulate impurities carried in the exhaust gas are intercepted by the dust filter plate 10 and fall into the dust box 21. The exhaust gas with the particulate impurities removed passes through the dust filter plate 10 reaches the activated carbon filter plate 17, and the odor in the exhaust gas is adsorbed by the activated carbon filter plate 17. The purified exhaust gas is discharged from the purification box 9 through the exhaust pump 19, which realizes the ventilation inside the welding room 1 and avoids the exhaust gas discharged from the welding room 1 from polluting the working environment. When a large amount of dust adheres to the dust filter plate 10, causing its filtering effect to decrease, the rotating motor 14 is started to drive the cross bar 12 and the rubber plate 13 to rotate at a high speed. During the rotation of the rubber plate 13, it continuously collides with the dust filter plate 10, thereby continuously beating the dust filter plate 10, so as to shake off the particulate impurities on the surface of the dust filter plate 10.
[0028] The device is controlled automatically by the controller 20. The control circuit of the controller 20 can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field. Therefore, the control method and circuit connection of the device will not be explained in detail.
