Description

Technical Field

[0001] This utility model relates to the field of welding fume treatment, specifically to a device for purifying and collecting welding fumes from metal products. Background Technology

[0002] During the welding process of metal products, a large amount of welding fumes and particulate matter are usually generated. These fumes not only harm the health of workers but also seriously pollute the working environment. Therefore, welding sites generally need to be equipped with fume purification and collection devices to collect and purify the fumes generated during the welding process in a timely manner.

[0003] Most existing welding fume purification devices rely on filter elements to filter and purify the fumes. While this can remove harmful particles to some extent, in actual use, welding fumes often contain larger metal slag, spatter, or other solid impurities. These large impurities, once inside the device, easily clog or damage the filter elements, shortening their lifespan and increasing maintenance costs. Although some existing technologies incorporate filter screens or baffles, their poorly designed structures often result in excessive airflow resistance or difficulty in disassembly and cleaning, affecting the long-term stable operation of the device.

[0004] Therefore, how to effectively intercept large-sized impurities through reasonable structural design before the dust enters the filter element, while ensuring convenient disassembly and easy cleaning, has become an urgent problem to be solved in the field of welding fume purification and collection devices.

[0037] like Figures 1 to 7 As shown, the metal product welding fume purification and collection device includes a housing 1, a filter assembly 6, a pipe 2, an air inlet hood 3, and a pre-filtration mechanism 8. The filter assembly 6 is disposed inside the housing 1; one end of the pipe 2 is connected to the air inlet hood 3, and the other end is connected to the filter assembly 6.

[0038] The filter assembly 6 includes a fan 601, a filter element 602, and a telescopic pipe 603. The air inlet of the fan 601 is connected to the output of the filter element 602, and the other end of the filter element 602 is connected to the telescopic pipe 603. The telescopic pipe 603 is connected to the pipe body 2, so that the fumes generated during the welding process pass sequentially through the air inlet hood 3, the pipe body 2, the telescopic pipe 603, and the filter element 602, and are finally drawn out by the fan 601, achieving efficient collection and purification of fumes.

[0039] The pre-filtration mechanism 8 is located inside the telescopic tube 603 and is used to perform preliminary filtration of the flue gas entering the device to remove large-sized impurities and prevent them from directly entering the filter element 602 and causing blockage or damage. Specifically, the pre-filtration mechanism 8 includes a housing 801, a filter screen 802, and bolts 803. The housing 801 is connected to the tube body 2. The filter screen 802 is installed at the bottom of the housing 801 and is fixedly connected by the bolts 803, so that the filter screen 802 can reliably intercept large-particle impurities and facilitates subsequent disassembly and cleaning.

[0040] In actual use, when welding operations generate fumes, the fumes are first drawn into the pipe body 2 through the air inlet hood 3, and then enter the pre-filtration mechanism 8. Large particles are trapped by the filter screen 802, while finer particles and fumes pass through the filter screen 802 into the telescopic pipe 603, and are further filtered by the filter element 602. Finally, the purified gas is discharged by the fan 601, thereby achieving efficient purification and collection of welding fumes.

[0041] In this embodiment, the device further includes a first adjustment mechanism 4 and a second adjustment mechanism 5, used to achieve multi-dimensional adjustment of the position of the air inlet hood 3. Through these adjustment mechanisms, the angle and height of the air inlet hood 3 can be flexibly adjusted according to the different positions of the welding station and the welded workpiece, thereby ensuring that the smoke and dust can be fully collected and improving purification efficiency.

[0042] The first adjustment mechanism 4 is used to adjust the pitch angle of the air inlet shroud 3. The first adjustment mechanism 4 includes a base 401, a first bracket 402, a second bracket 406, and a telescopic rod 405; wherein, the base 401 is fixedly connected to the first bracket 402, the first bracket 402 and the second bracket 406 are rotatably connected, and the second bracket 406 and the telescopic rod 405 are slidably connected, thereby forming a movable support structure.

[0043] Furthermore, the first adjustment mechanism 4 also includes a first hydraulic cylinder 403 and a second hydraulic cylinder 404. The cylinder body of the second hydraulic cylinder 404 is rotatably connected to the second bracket 406, and its output end is rotatably connected to the telescopic rod 405, used to drive the telescopic rod 405 to extend or retract, thereby realizing the pitch adjustment of the air inlet shroud 3; the cylinder body of the first hydraulic cylinder 403 is rotatably connected to the first bracket 402, and its output end is rotatably connected to the second bracket 406, used to drive the second bracket 406 to rotate relative to the first bracket 402, thereby further realizing angle adjustment. Through the coordinated action of the first hydraulic cylinder 403 and the second hydraulic cylinder 404, the air inlet shroud 3 can achieve a wide range of pitch adjustment to meet the needs of different working conditions.

[0044] The second adjustment mechanism 5 is used to adjust the height of the air inlet hood 3 in the vertical direction. The second adjustment mechanism 5 includes a limiting member 501, a screw 502, and a support frame 503. The limiting member 501 is slidably connected to the base 401, allowing the air inlet hood 3 to move vertically; the support frame 503 is rotatably connected to the screw 502, and the screw 502 is threadedly connected to the base 401. By rotating the screw 502, the base 401 can be raised or lowered, achieving precise adjustment of the height of the air inlet hood 3.

[0045] In actual use, the operator can first adjust the second adjustment mechanism 5 by rotating the screw 502 according to the location of the welding fume generation point, thereby changing the height of the air inlet hood 3; then, as needed, by operating the first hydraulic cylinder 403 and the second hydraulic cylinder 404, the operator can drive the second bracket 406 and the telescopic rod 405 to move, thereby adjusting the pitch angle of the air inlet hood 3. Through the above adjustment method, the air inlet hood 3 can be flexibly aligned with the welding point, ensuring that the fume is drawn into the pipe body 2 in a timely and effective manner, thereby improving the fume collection efficiency, extending the service life of the filter element 602, and improving the working environment.

[0046] In this embodiment, the device further includes an adjustment component 7 for further adjusting the position of the air inlet shroud 3, so as to achieve precise positioning of the air inlet shroud 3 on the basis of the first adjustment mechanism 4 and the second adjustment mechanism 5 completing a wide range of angle and height adjustments, thereby enabling the air inlet shroud 3 to be more accurately aligned with the welding operation point.

[0047] The adjusting assembly 7 includes a rod 701, a nut 702, a limiting plate 703, and a limiting groove 704. Specifically, one end of the rod 701 is fixedly connected to the air inlet hood 3 so as to drive the air inlet hood 3 to move during the adjustment process; the limiting plate 703 is fixedly connected to the telescopic rod 405, and the limiting groove 704 is formed on the limiting plate 703, and the limiting groove 704 is slidably connected to the rod 701, thereby allowing the rod 701 to move in the sliding direction under the guidance of the limiting groove 704.

[0048] Furthermore, the nut 702 is threaded onto the rod 701, and its end face can be pressed against the surface of the limiting plate 703 by tightening, thereby restricting the movement of the rod 701 and locking the position of the air inlet hood 3. The operator can unlock and adjust the air inlet hood 3 and fix its position by loosening or tightening the nut 702, respectively. The adjustment operation is simple and the positioning is reliable.

[0049] In practical use, the operator can first adjust the height and angle of the air inlet hood 3 over a wide range using the first adjustment mechanism 4 and the second adjustment mechanism 5, based on the location of the welding point, to roughly align it with the welding area. Then, the operator can use the adjustment component 7 to push the rod 701 to slide within the limiting groove 704, achieving fine-tuning of the air inlet hood 3. Once the air inlet hood 3 is adjusted to the target position, the nut 702 is tightened to press it against the surface of the limiting plate 703, thereby locking the relative position of the air inlet hood 3. Through the above operations, the air inlet hood 3 can ensure both the flexibility of a wide range of adjustments and the stability of precise positioning, thus effectively improving the collection efficiency of welding fumes.

[0050] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
