It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1-6 As shown, a welding purification and smoke removal mechanism for iron-chromium-aluminum foil strips in this embodiment includes a welding box 1. A filter box 2 is fixedly connected to the upper surface of the welding box 1. A connecting pipe 201 is fixedly connected to one end of the filter box 2, and the connecting pipe 201 passes through the welding box 1. A lifting assembly is provided on the upper surface of the filter plate 3.

[0031] The smoke accumulated at the top of the welding box 1 can be extracted through the connecting pipe 201. The extracted smoke enters the filter box 2 and is filtered by the filter screen 4. The filter screen 4 can block particulate impurities in the smoke and prevent them from being discharged with the smoke. The filter plate 3 can be removed by the lifting component to clean or replace the filter screen 4.

[0032] The filter box 2 has a guide plate 5 inside, which is triangular in shape. The bottom inner wall of the filter box 2 has a discharge port 12. The filter box 2 has a collection drawer 6 inside, and the side surface of the collection drawer 6 has a draw ring. The other end of the filter box 2 is movably connected to a smoke exhaust pipe 7. One end of the filter box 2 has a slot 14.

[0033] The guide plate 5 is installed between the filter plate 3 and the connecting pipe 201 and is in contact with the filter plate 3. The particulate impurities filtered and blocked by the filter screen 4 fall downwards and onto the guide plate 5. The particulate impurities that accumulate on the guide plate 5 will slide to the lower side and then fall from the discharge port 12 into the collection drawer 6 below, making it easy to remove and clean later.

[0034] A first mounting block 13 is fixedly connected to the side surface of the filter box 2, and a second mounting block 15 is fixedly connected to the side surface of the exhaust pipe 7. The exhaust pipe 7 is located in the slot 14. The side surface of the first mounting block 13 contacts the second mounting block 15. A bolt 16 is threadedly connected to the inside of the second mounting block 15. A nut 17 is threadedly connected to the side surface of the bolt 16. The bolt 16 passes through the first mounting block 13.

[0035] The exhaust pipe 7 and the filter box 2 can be fixedly connected together by bolts 16 and nuts 17. When the exhaust pipe 7 is installed, it is inserted into the slot 14 to increase the sealing of the connection.

[0036] The welding box 1, door 22, inclined plate 20, and tilted transparent glass 21 are used to shield the fumes generated during the welding process, preventing them from being directly emitted into the workshop. The fumes are drawn upwards and extracted by the exhaust fan 9. During the extraction process, the fumes pass through the filter box 2 and activated carbon box 10 in sequence, removing particulate impurities and harmful gases from the fumes. This ensures that the discharged fumes are free of particulate impurities and harmful gases, thus avoiding any impact on the health of the operators. Furthermore, the smoke is discharged into the air by the smoke guide pipe 11, ensuring that the visibility environment in the workshop is not damaged.

[0037] A mounting bracket 8 is fixedly connected to the rear surface of the welding box 1. An exhaust fan 9 is fixedly connected to the upper surface of the mounting bracket 8. The exhaust fan 9 is electrically connected to an external power source, which is prior art and known to those skilled in the art. An activated carbon box 10 is fixedly connected to the upper surface of the welding box 1. The activated carbon box 10 is filled with activated carbon plates for filtering harmful gases in the smoke. A smoke guide pipe 11 is provided on the side surface of the activated carbon box 10 for guiding the filtered smoke upwards and discharging it to the upper atmosphere.

[0038] The front surface of the welding box 1 is provided with a door 22 and a transparent glass 21. The welding process can be observed through the transparent glass 21. The transparent glass 21 is installed at an angle to guide the smoke and make it easier to see. An inclined plate 20 is fixedly connected to the inner wall of the welding box 1. Holes 23 are symmetrically arranged through the front surface of the door 22. The operator's arm can be inserted into the welding box 1 through the holes 23, which can reduce the emission of smoke into the workshop air.

[0039] The welding box 1 has a cable outlet 24 on its side surface. When the welding gun is placed into the welding box 1, the connecting wire can be passed out through the cable outlet 24 and connected to the welding machine. A horizontal plate 18 is fixedly connected to the side surface of the welding box 1, and a support frame 19 is fixedly connected to the upper surface of the horizontal plate 18. The side surface of the smoke guide pipe 11 is in contact with the support frame 19. The input end of the exhaust fan 9 is fixedly connected to the exhaust pipe 7, and the output end of the exhaust fan 9 is connected to the activated carbon box 10 through a pipe.

[0040] The working principle of this utility model is as follows: When using this device to weld iron-chromium aluminum foil strips, the welding gun is placed inside the welding box 1, and the connecting wire is passed out from the outlet 24 and connected to the electric welding machine. After placing the iron-chromium aluminum foil strip to be welded into the welding box 1, the door 22 is closed. The operator turns on the exhaust fan 9, extends his arm into the welding box 1 through the hole 23, and uses the welding gun to weld the iron-chromium aluminum foil strip. The fumes generated during the welding process enter the filter box 2 through the connecting pipe 201. When passing through the filter screen 4, the particulate impurities are blocked, fall onto the guide plate 5 and slide down from the discharge port 12 into the collection drawer 6. The fumes after filtering the impurities enter the activated carbon box 10 for harmful substance treatment, and finally are discharged to the high altitude through the smoke guide pipe 11.
