Since welding fumes often contain welding impurities, if these impurities enter the purification device, they may cause blockage of subsequent filters, reducing purification efficiency and equipment lifespan. To address these issues, we have designed a factory welding fume purification device to provide an alternative technical solution. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1-7 A factory welding fume purification device includes a purification machine 1, a ventilation duct 2 at one end of the purification machine 1, a fume extraction box 3 at one end of the ventilation duct 2, a rotatable rectangular rotating plate 4 at the top and bottom of one end of the fume extraction box 3, and elastic shielding cloths 5 on both sides of one end of the fume extraction box 3. The rectangular rotating plate 4 and the elastic shielding cloth 5 are fixedly connected.
[0025] The outer side of the smoking box 3 is provided with a rotating mechanism for rotating the rectangular rotating plate 4;
[0026] The smoking box 3 is equipped with a removable filter plate 7 inside, and a limiting mechanism for limiting the filter plate 7 is provided on one side of the filter plate 7.
[0027] The rotating mechanism includes a hydraulic cylinder 6, with a rectangular moving block 8 fixed at the output end of the hydraulic cylinder 6. The top and bottom of the rectangular moving block 8 are rotatably connected to an oblique rotating column 9 via a pin. A Z-shaped fixed column 10 is fixed at one end of the outer side of the smoking box 3. A vertical light rod 11 is fixed at the top and bottom of the Z-shaped fixed column 10. A vertical sliding tube 12 is slidably connected to the outer side of the vertical light rod 11. The oblique rotating column 9 and the vertical sliding tube 12 are rotatably connected via a pin. A rectangular transmission block 13 is rotatably connected to the side of the vertical sliding tube 12 near the rectangular rotating plate 4 via a pin. A rectangular rotating block 14 is rotatably connected to one end of the rectangular transmission block 13 via a pin. A longitudinal rotating column 15 is fixed inside the rectangular rotating block 14. The longitudinal rotating column 15 penetrates the interior of the elastic shielding cloth 5 and is rotatably connected to the elastic shielding cloth 5. The rectangular rotating block 14 penetrates the outer side of the rectangular rotating plate 4 and is fixedly connected to the rectangular rotating plate 4.
[0028] The rectangular rotating plate 4 has an arc-shaped fixing block 16 inside. The longitudinal rotating column 15 passes through the arc-shaped fixing block 16 and is rotatably connected to the arc-shaped fixing block 16 through a bearing. The arc-shaped fixing block 16 is fixedly connected to the smoking box 3. The arc-shaped fixing block 16 allows the longitudinal rotating column 15 to rotate better, so that the rotation of the longitudinal rotating column 15 can drive the elastic shielding cloth 5 to rotate.
[0029] The vertical sliding tube 12 has a vertical circular groove inside. The vertical smooth rod 11 is located inside the vertical circular groove and is slidably connected to the vertical sliding tube 12 through the vertical circular groove. The vertical circular groove allows the vertical sliding tube 12 to slide vertically on the outside of the vertical smooth rod 11. The operation of the hydraulic cylinder 6 enables the vertical sliding tube 12 to slide vertically.
[0030] Here, the operation of the hydraulic cylinder 6 enables the rectangular moving block 8 to move. The movement of the rectangular moving block 8, through the setting of the inclined rotating column 9, enables the vertical sliding tube 12 to slide vertically on the outside of the vertical light rod 11. The sliding of the vertical sliding tube 12, through the rectangular transmission block 13, enables the rectangular rotating block 14 to drive the longitudinal rotating column 15 to rotate. The rotation of the longitudinal rotating column 15 enables the rectangular rotating plate 4 to rotate, thereby adjusting the distance between the two rectangular rotating plates 4 to adapt to different welding fume collection needs.
[0031] The limiting mechanism includes a U-shaped push block 17. The U-shaped push block 17 is fixed on one side of the filter plate 7. A U-shaped limiting plate 19 is slidably connected to the top of the U-shaped push block 17. A rectangular limiting groove adapted to the U-shaped limiting plate 19 is opened inside the smoking box 3. A rectangular push block 18 is fixed on one side of the U-shaped limiting plate 19. Anti-slip textures are evenly distributed on the outer side of the rectangular push block 18. A vertical rigid spring 20 is provided at the bottom of the U-shaped limiting plate 19 and inside the U-shaped push block 17.
[0032] The inside of the U-shaped push block 17 is provided with a vertical rectangular groove. The U-shaped limiting plate 19 is located inside the vertical rectangular groove and is slidably connected to the U-shaped push block 17 through the setting of the vertical rectangular groove. This allows the rectangular push block 18 to be pushed, so that the rectangular push block 18 can slide inside the U-shaped push block 17. The movement of the rectangular push block 18 causes the vertical rigid spring 20 to be deformed by force.
[0033] When the filter plate 7 needs to be disassembled, the rectangular push block 18 is pushed upward. The push of the rectangular push block 18 allows the U-shaped limiting plate 19 to slide vertically inside the loop-shaped push block 17, thereby allowing the U-shaped limiting plate 19 to move out of the smoke box 3. This releases the restriction of the rectangular push block 18 on the loop-shaped push block 17, allowing the filter plate 7 to move out of the smoke box 3 and be disassembled for subsequent maintenance and replacement.
[0034] Through a series of designs, the angles of the two rectangular rotating plates 4 can be adjusted to effectively capture the welding fumes that diffuse during the welding process, improving purification efficiency and ensuring improved air quality inside the factory. The filter plate 7 can effectively isolate large welding impurities and prevent them from entering the interior of the purifier 1, thereby avoiding clogging of subsequent filters and extending the service life of the equipment. The easy disassembly design of the filter plate 7 greatly simplifies the maintenance and cleaning process of the equipment, allowing users to easily perform regular inspections and replacements.
[0035] Working principle: The operation of hydraulic cylinder 6 enables rectangular moving block 8 to move. The movement of rectangular moving block 8, through the setting of inclined rotating column 9, enables vertical sliding tube 12 to slide vertically on the outside of vertical smooth rod 11. The sliding of vertical sliding tube 12, through rectangular transmission block 13, enables rectangular rotating block 14 to drive longitudinal rotating column 15 to rotate. The rotation of longitudinal rotating column 15 enables rectangular rotating plate 4 to rotate, thereby adjusting the distance between the two rectangular rotating plates 4 to adapt to different welding fume collection needs.
[0036] When the filter plate 7 needs to be disassembled, push the rectangular push block 18 upward. The push of the rectangular push block 18 allows the U-shaped limiting plate 19 to slide vertically inside the loop-shaped push block 17, thereby allowing the U-shaped limiting plate 19 to move out of the smoke box 3. This releases the restriction of the rectangular push block 18 on the loop-shaped push block 17, allowing the filter plate 7 to move out of the smoke box 3 and be disassembled for subsequent maintenance and replacement.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
