[0044] Please refer to Figure 1 , Figure 2 and Figure 7 The purification component 4 includes a purification frame 41, which is plugged into the box 1. The inner wall of the purification frame 41 is sequentially installed with an activated carbon layer 42 and a photocatalyst filter 43.

[0046] Please refer to Figure 1 and Figure 2 The bottom of the box body 1 is equipped with universal wheels 118, which can facilitate the staff to push the box body 1 to move, thereby meeting the use requirements of different places.

[0047] When used specifically, the working principle of the present invention is as follows:

[0048] Firstly, when in use, the staff can move the equipment to a suitable position via the universal wheel 118, the vacuum pump 105 can draw the external welding smoke into the interior of the box body 1 through the smoke inlet, and the water pump 22 can spray the water in the open water tank 21 into the interior of the box body 1 through the water outlet pipe 23 and the atomizing nozzle 24, the atomized water can cool the welding smoke entering the box body 1, and at the same time, some larger particulate impurities in the welding smoke can be flushed into the open water tank 21.

[0049] Next, the metal fine filter 103 can filter out some smaller particle impurities in the welding smoke. After that, the activated carbon layer 42 and the photocatalyst filter 43 can purify harmful organic substances in the flue gas, such as formaldehyde, benzene, ammonia, sulfur dioxide, carbon monoxide, nitrogen oxides, etc., which affect human health. The purified flue gas can be dried by the desiccant in the dehumidification drawer 106 to avoid the impact of over-humidified gas on factory equipment, thereby completing the purification of the welding smoke.

[0050] Finally, after the welding smoke purification is completed, the staff can start the motor 31, and the motor 31 can drive the first rotating shaft 32 and the eccentric wheel 33 to rotate. The eccentric wheel 33 can push the metal fine filter 103 to reciprocate under the cooperation of the first spring 102 and the fixed block 101, so that the impurities attached to the metal fine filter 103 can be shaken off into the wastewater in the open water tank 21. At the same time, the first transmission wheel 34 on the first rotating shaft 32 can drive the second rotating shaft 35 and the fan blade 38 to rotate under the cooperation of the transmission belt 37 and the second transmission wheel 36. The wind force generated by the fan blade 38 can be tilted to blow toward the metal fine filter 103 under the cooperation of the inclined guide plate 39, thereby reducing the dust and impurities on the metal fine filter 103 from falling to the inner side of the metal fine filter 103, facilitating the rapid cleaning of the dust and impurities on the metal fine filter 103, and reducing the clogging of the metal fine filter 103 during subsequent use. After completing the above operations, the staff can drain the water in the open water tank 21 through the drain pipe 108.

[0051] In summary, the welding smoke purification equipment for sheet metal welding can quickly cool down the welding smoke entering the inside of the box 1 through the cooling component 2, and the cooled welding smoke can be purified and filtered through the metal fine filter 103 and the purification component 4. The filtered welding smoke can be dehumidified through the dehumidification box 104 and then discharged, thereby completing the purification of the welding smoke. The dust and impurities on the metal fine filter 103 can be quickly cleaned through the cleaning component 3, reducing the clogging of the metal fine filter 103 during subsequent use.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto.
