TECHNICAL FIELD
[0001] The utility model relates to a welding fume suction equipment. BACKGROUND
[0002] In the traditional welding operation scene, the smoke and harmful gas generated in the welding process have always been a difficult problem to be solved. When welding work is carried out, a large amount of metal particles, scales and other harmful substances will be emitted together with the smoke. These smoke diffuses in the working environment, which poses a serious threat to the health of workers. Long-term exposure to such an environment may cause respiratory diseases, lung damage and other health problems. At the same time, these smoke also greatly reduces the air quality of the working environment, making the workplace dirty and uncomfortable, which not only affects the workers' working mood and efficiency, but also may have adverse effects on the surrounding environment.

[0039] The middle core dust suction hood head 9 always keeps parallel to the horizontal plane.
[0040] Usage:
[0041] Firstly, move the equipment. With the aid of the lockable universal walking wheels 2 of the bottom moving seat 1, the equipment can be conveniently pushed to the position where welding fume suction is needed. When reaching the specified position, the locking function of the walking wheels is used to stably fix the equipment in place, preventing it from moving during the work process.
[0042] Then, adjust the height. The height of the auxiliary plate body 6 and the dust suction mechanism 7 is adjusted according to the actual situation by operating the controller 8 to control the secondary controllable telescopic equipment 5, so as to achieve the best dust suction effect and ensure that the dust suction hood can be more effectively aligned with the smoke source.
[0043] Then, adjust the side dust cover head angle. If better alignment of the welding fume suction position is needed in actual use to improve the dust collection efficiency, the angle of the side dust cover head 12 can be adjusted. The specific operation is as follows: gently push the push plate body 18 with your hand, at this time the insertion limiting protrusion 19 will be detached from the limiting hole body 14, and the spring 20 will be compressed. Then turn the side dust cover head 12 to the desired angle, after the adjustment is completed, release the push plate body 18, and under the rebound force of the spring 20, the insertion limiting protrusion 19 will be inserted into the corresponding limiting hole body 14, thereby limiting the rotation of the side dust cover head 12. Since the core guide telescopic rod body 16 is slidably provided with the core sliding tube body 17, this design makes the entire adjustment process more stable and reliable.
[0044] Finally, start the device. Start the bag dust collector 4 through the controller 8, at this time the middle core dust cover head 9 and the side dust cover head 12 will start to suck the welding fume through the dust suction hole body 10, and the fume will be transported to the bag dust collector 4 for filtering treatment to ensure that the fume can be effectively sucked in and fully filtered.
[0045] Precise alignment: angle adjustable, the angle of the side dust cover head 12 on both sides of the middle core dust cover head 9 is adjustable. When better alignment of the welding fume suction position is needed, the insertion limiting protrusion 19 can be detached from the limiting hole body 14 by pushing the push plate body 18, the spring 20 is compressed, and then the side dust cover head 12 is turned to the desired angle, and then the push plate body 18 is released to insert the insertion limiting protrusion 19 into the corresponding limiting hole body 14 to fix the angle. This design can flexibly adjust the angle of the dust cover head according to different welding scenes and fume generation conditions, improving the dust collection efficiency.
[0046] Good dust collection effect: the lower side of the middle core dust cover head 9 is provided with a plurality of evenly distributed dust suction hole bodies 10, which work together with the side dust cover head 12 to more comprehensively suck the welding fume. At the same time, the middle core dust cover head 9 and the side dust cover head 12 are both in communication with the bag dust collector 4 through the pipeline, and the fume is filtered by the bag dust collector 4 to ensure that the fume can be effectively sucked in and filtered, reducing the impact on the working environment and the health of the operators.
[0047] Improve the quality of the working environment: by effectively collecting and filtering the fume generated during the welding process, the device significantly reduces the air pollution in the workplace, protects the respiratory health of workers, and provides a cleaner and safer working environment.
[0048] Highly adjustable: equipped with a two-stage controllable telescopic device 5, the height of the auxiliary plate body 6 and the dust collection mechanism 7 can be adjusted according to actual needs through the controller 8. This function enables the device to adapt to different height welding work environments, ensuring optimal dust collection, better aligning with the welding smoke source, and improving smoke suction efficiency.
[0049] The above describes the present application and its embodiments, which are not restrictive, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative spirit of the present application, without creative design, similar structure and embodiments similar to the technical solution should belong to the protection scope of the present application.
