[0021] Implementation Method 1 Reference Figures 1 to 4 This embodiment, as an optional embodiment of this application, discloses a factory welding dust removal device, including a sealing cover 1, the sealing cover 1 including a support frame 101, a connecting plate 102 for connecting the welding device on the support frame 101; and a shielding curtain 103 on the support frame 101. When in use, the sealing cover 1 is connected to the suspension arm of the external welding equipment through the connecting plate 102 to ensure that the sealing cover 1 always covers the welding point; Furthermore, an adjusting frame 7 is also provided inside the sealing cover 1. The adjusting frame 7 includes a first adjusting rod 701 and a second adjusting rod 702. One end of the first adjusting rod 701 is hinged to the connecting plate 102 via a pin, and the other end is provided with a rotating ball seat 703. The second adjusting rod 702 is provided with an adjusting ball 704 adapted to the rotating ball seat 703. The second adjusting rod 702 is also provided with a limiting cover 705 adapted to the rotating ball seat 703. A fixing nut 706 is provided on the limiting cover 705. In the above structure, the second adjusting rod 702 can rotate within a wider range relative to the first adjusting rod 701, thereby improving the adjustability of the adjusting frame 7; Furthermore, the dust removal device also includes a dust removal pipe 2, the inlet end of which is inserted into the sealing cover 1. The dust removal pipe 2 is installed on the first adjusting rod 701 and the second adjusting rod 702 by cable ties or fixing clips. A collection tray 8 is provided at the inlet end of the dust removal pipe 2. The collection tray 8 has a conical or square pyramidal structure, and the small end of the collection tray 8 is inserted and connected to the inlet end of the dust removal pipe 2. The cone-shaped collection plate 8 can form a larger negative pressure zone at the outlet end of the dust removal pipe 2, which is conducive to collecting and diffusing welding fumes, thereby improving the efficiency of waste gas treatment. Furthermore, the dust removal device also includes a negative pressure fan 3, the inlet end of which is connected to the outlet end of the dust removal pipe 2, and its outlet end is connected to the inlet end of another section of the dust removal pipe 2. At the same time, the outlet end of this section of the dust removal pipe 2 is also connected to a spiral separator 4. The top of the spiral separator 4 is provided with an exhaust port, and the bottom is provided with a discharge port. The discharge port is connected to a waste collection box 5, and the exhaust port is connected to a filter module 6. The waste collection box 5 includes a box body 501. Along the length of the box body 501, one end of the box body 501 is provided with a feed pipe 502 connected to the discharge port, and the other end is provided with an exhaust pipe 503. An auxiliary filter module 504 is provided on the exhaust pipe 503. The auxiliary filtration module 504 includes a connector filled with activated carbon, and filter screens are provided at both the inlet and outlet ends of the connector. Furthermore, a discharge box 507 is provided at the bottom of the box 501, and the discharge box 507 is slidably inserted into the box 501 along the width direction of the box 501; at the same time, a number of baffles 505 are provided at the top of the box 501, and each baffle 505 is arranged sequentially along the length direction of the box 501. Each baffle 505 is provided with a number of ventilation holes 506, and the space of each ventilation hole 506 on each baffle 505 decreases sequentially along the airflow direction. The top of the discharge box 507 is fully open, and each of the baffles 505 is located directly above the discharge box 507; During use, the airflow carrying large particulate impurities enters the housing 501 through the feed pipe 502. As the volume of the housing 501 increases, the airflow speed slows down. At this time, the large particulate impurities will fall into the discharge box 507 under their own gravity. At the same time, with the interception effect of the baffle 505, some small particulate suspended impurities will fall into the discharge box 507 along the surface of the baffle 505, thereby realizing the separation and recovery of large particulate impurities. The filter module 6 includes a connecting sleeve 601, the inlet end of which is threadedly connected to the exhaust port; the connecting sleeve 601 is provided with a plurality of adsorption modules 602, and each adsorption module 602 is sequentially filled with activated carbon, molecular sieve and activated alumina along the airflow direction. Furthermore, the connecting sleeve 601 is also provided with a plurality of buffer cavities 603, and each of the buffer cavities 603 is disposed between each of the adsorption modules 602. By using activated carbon, molecular sieves, and activated alumina, different pollutants can be adsorbed in stages, further improving the cleanliness of the exhaust gas and reducing environmental pollution. At the same time, the buffer chamber 603 can regulate the airflow rate to ensure the full absorption of harmful substances.

[0022] During use, welding operations are carried out inside the sealed cover. At the same time, the air inside the sealed cover is drawn out by the negative pressure fan and dust removal pipe, and the exhaust gas generated by welding is transported to the spiral separator. Inside the spiral separator, large particles of impurities are separated from the flue gas. The large particles of impurities enter the waste residue collection box from the bottom discharge port, while the flue gas is directly discharged into the air after being adsorbed and filtered by the filter module. Compared with the prior art, this application extracts the waste gas generated during welding from the welding source and performs separation and adsorption treatment on it, thereby reducing the content of harmful substances in the exhaust gas as much as possible, thus reducing the adverse environmental impact of welding. Secondly, the dust removal device described in this application has a simple structure and is easy to use, which helps to reduce the cost and difficulty of use of the equipment.

[0023] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
