[0002] In industrial production, especially in welding operations, the generation of smoke is an inevitable problem. Traditional methods of welding smoke treatment mostly use point-to-point or local centralized treatment, but these methods are not ideal in tall factories. Especially in the welding process of large structural parts, due to the large number of welding stations, large workpiece size, and frequent hoisting, smoke often suspends in the air at a height of 6-8 meters and is difficult to be effectively discharged. This causes smoke in the factory, affecting the health of workers and production efficiency.
[0003] Existing technologies face many challenges in welding plants with large spaces. First, due to the scattered welding points, traditional dust removal systems are difficult to cover all workstations and are inefficient in capturing smoke. Second, existing ventilation and dust removal systems often require a large investment and high operating costs. In addition, these systems may take up valuable production space, and are not effective in collecting welding smoke in large plants, and cannot meet indoor emission standards. Therefore, a new type of ventilation and dust removal system is urgently needed to solve the above technical problems. Utility Model Content

[0008] As a further improvement of the above solution, the dust cleaning component includes a movable block, brush bodies are arranged around the movable block, and the movable block is movably arranged in the return air port.
[0009] The technical effect of the above improvements is: the design of the cleaning components, especially the brush body around the movable block, can effectively clean the inside of the return air duct, maintain smooth air circulation, and reduce the maintenance frequency and cost caused by smoke accumulation.
[0010] As a further improvement of the above solution, the upper and lower ends of the movable block are respectively provided with guide rings through the support blocks, and the guide rings are inserted and slid in the guide rod; the guide rod is arranged in the return air outlet through the fixed block.
[0011] The technical effect of the above improvement is: the coordinated use of the guide rings and guide rods at the upper and lower ends of the movable block ensures the smooth movement of the cleaning components in the return air duct, improves the cleaning efficiency, and also extends the service life of the equipment.
[0012] As a further improvement of the above solution, the guide ring and the guide rod are transitionally matched and are both arranged in a circular shape.
[0013] The technical effect of the above improvement is: the circular transition fit design between the guide ring and the guide rod reduces friction, makes the movement of the cleaning parts smoother, reduces operating noise, and improves the comfort of the working environment.

[0020] In order to enable those skilled in the art to better understand the technical solution, the utility model is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0021] like Figure 1-Figure 2 As shown, the specific scheme of this embodiment is: a replacement ventilation dust removal system for a tall factory building, including a dust removal host 1, a grille air supply port 2 and a spherical nozzle 3 are respectively arranged on both sides of the dust removal host 1, a return air duct 4 is arranged on the top of the dust removal host 1, and a sealing plate 5 is arranged on the return air duct 4; a dust cleaning component for cleaning the interior is arranged in the return air duct 4, and a sealing plate 5 is arranged on the side end of the return air duct 4. The return air duct 4 is provided with a return air port 6
[0022] Specifically, the dust removal host 1 is the core component of the system and is responsible for the dust removal function of the entire system. The grille air supply port 2 and the spherical nozzle 3 are respectively located on both sides of the dust removal host 1 to help the suspended smoke and dust move upward for capture by the return air duct 4. The return air duct 4 is located at the top of the dust removal host 1. Its function is to collect the smoke and dust pushed up by the grille air supply port 2 and the spherical nozzle 3, and transport it to the dust removal host 1 for purification. The sealing plate 5 is arranged above and on the side of the return air duct 4 to ensure that the airflow and smoke will not escape from the system, maintain the airtightness and dust removal efficiency of the system. The cleaning component is arranged inside the return air duct 4, which is used to regularly clean the accumulated dust in the duct to ensure unobstructed airflow.
[0023] During the working process, the ball nozzle 3 at the bottom, the grille air supply port 2 and the top return air are used. The upward air supply angle is adjusted according to the situation of the on-site welding station to give an upward thrust to the smoke generated by welding, pushing the original 6-8m suspended smoke to move upward, and is captured by the return air port 6 of the grille on the return air duct 4 and enters the dust removal host 1 for purification.
[0024] In the dust removal main unit 1, smoke is filtered and purified, and then the clean air is discharged back into the factory. The dust cleaning component is responsible for regularly cleaning the dust accumulated in the return air duct 4 to ensure the long-term and effective operation of the system.
[0025] like Figure 2-Figure 3 As shown, as a preferred embodiment of the above embodiment, the dust cleaning component includes a movable block 7, and a brush body 8 is arranged around the movable block 7.

The guide rings 11 and the guide rods 10 are transitionally matched and are both arranged in a circular shape. The movable block 7 is provided with a step groove 9.
[0026] Specifically, during operation, the movable block 7 cleans along the track in the return air port 6 through the coordinated action of the guide ring 11 and the guide rod 10. The brush body 8 cleans the smoke and dust in the pipeline to ensure the smooth flow of the system. This design not only improves the cleaning efficiency, but also facilitates installation and maintenance due to its modular and compact design.
[0027] The movable block 7 is the core of the dust cleaning component. It is located in the return air port 6 and can be moved when needed. Brush bodies 8 are arranged around the movable block 7, and these brush bodies 8 are responsible for cleaning the smoke and dust in the return air port 6. The design of the brush bodies 8 increases the cleaning effect. Guide rings 11 are located at the upper and lower ends of the movable block 7 and are arranged by support blocks 12. The function of these guide rings 11 is to ensure the smooth movement of the movable block 7 in the return air port 6.
