Therefore, it is often necessary to separately sort out the welds after welding, such as grinding, which makes the processing operation more cumbersome. Therefore, a welding equipment for processing environmental protection facilities is proposed to improve the above problems. Summary of the invention

[0022] Based on the coordinated arrangement of the above structure, after the round tube is inserted from the operating port 101, the air pump 11 is used to inflate the air cavity 102, so that the air pressure inside the air cavity 102 increases, thereby clamping and fixing the round tube through the elastic ring band 2. Since the elastic ring band 2 fits tightly against the surface of the round tube, the smoke generated during welding can be prevented from overflowing the welding box 1.

[0023] In addition, a fume suction device 12 is installed on the outside of the welding box 1, the output end of the fume suction device 12 extends to the inside of the welding box 1, and the fume suction device 12 has a built-in filtering structure. The fume suction device 12 is used to remove the fume generated during the welding process, and the harmful substances in the fume are filtered through the internal filtering structure.

[0024] Among them, a movable ring 3 is coaxially arranged on the inner side of the welding box 1, and the movable ring 3 is rotatably installed on the inner side of the welding box 1. A driving mechanism for driving the movable ring 3 to rotate is installed on the welding box 1. Specifically, the driving mechanism includes a first transmission gear 5 and a driving motor 13. The driving motor 13 is installed on the side end of the welding box 1, and the first transmission gear 5 is rotatably installed on the side end of the welding box 1. The circumferential side end of the movable ring 3 is equidistantly and integrally provided with a transmission tooth block 4 meshing with the first transmission gear 5.

[0025] Based on the above structure, the driving motor 13 drives the first transmission gear 5 to rotate, and the first transmission gear 5 drives the movable ring 3 to rotate through the transmission gear block 4, thereby driving the welding head 7 to rotate, and the round tube is welded for one circle without rotating the round tube, making welding more convenient. A welding unit is installed on the inner wall of the movable ring 3, and the welding unit includes a pan head 6, a welding head 7 and a sorting part 10. The pan head 6 is installed on the inner wall of the movable ring 3, and the welding head 7 is installed on the pan head 6, and the welding end of the welding head 7 is arranged toward the center of the movable ring 3. A mounting frame 8 is installed on the welding head 7, and the sorting part 10 is installed on the side of the mounting frame 8 away from the rotation direction of the welding head 7. The sorting part 10 includes a friction wheel 1001, a transmission assembly, a sorting wheel 1004 and a scraper 1005. The friction wheel 1001 is rotatably installed on the inner side of the mounting frame 8 and fits with the outer wall of the circular tube. The sorting wheel 1004 is rotatably installed on the inner side of the mounting frame 8, the transmission assembly is installed between the friction wheel 1001 and the sorting wheel 1004, and the scraper 1005 is fixed to the inner side of the mounting frame 8 and fits with the sorting wheel 1004.

[0026] The welding equipment for processing environmental protection facilities is configured such that the welding head 7 is installed on the inner side of the movable ring 3, and the movable ring 3 is rotatably installed on the inner side of the welding box 1. The movable ring 3 can be driven by a driving mechanism to rotate with the welding head 7, so that the round tube is welded for one circle without rotating the round tube, thereby making the welding more convenient. In addition, a finishing part 10 including a friction wheel 1001, a transmission component, a finishing wheel 1004 and a scraper 1005 is provided at the welding head 7. During the process of the welding head 7 rotating around the round tube, the friction force between the friction wheel 1001 and the round tube can be utilized to make the friction wheel 1001 rotate, and the finishing wheel 1004 can be driven to rotate by the transmission component, and the welding part of the round tube can be finished by the finishing wheel 1004. Excess welding liquid adheres to the surface of the finishing wheel 1004, and is scraped off by the scraper 1005 as the finishing wheel 1004 rotates to the scraper 1005, thereby ensuring the stable finishing effect of the finishing wheel 1004, thereby improving the welding quality of the round tube, and there is no need to finish the welding part at a later stage, thereby improving the processing efficiency.

[0027] In order to ensure that the force on the round tube is symmetrical, two welding units are provided, and the two welding units are symmetrically installed on the inner side of the movable ring 3, which can ensure that the force on the round tube is symmetrical and not prone to deviation, thereby facilitating the stability of welding.

[0028] The transmission assembly includes a second transmission gear 1002 and a third transmission gear 1003 . The second transmission gear 1002 is coaxially fixed to the friction wheel 1001 , and the third transmission gear 1003 is coaxially fixed to the finishing wheel 1004 . The second transmission gear 1002 is meshed with the third transmission gear 1003 .

[0029] Based on the matching arrangement of the above structure, when the welding head 7 rotates around the round tube, the friction force between the friction wheel 1001 and the round tube is used to make the friction wheel 1001 rotate, and through the meshing action of the second transmission gear 1002 and the third transmission gear 1003, the sorting wheel 1004 rotates, and the sorting wheel 1004 is used to sort the welding point of the round tube.

[0030] Furthermore, the diameter of the second transmission gear 1002 is greater than that of the third transmission gear 1003. The second transmission gear 1002 cooperates with the third transmission gear 1003 to transmit the information, and also accelerates the rotation of the finishing wheel 1004 relative to the friction wheel 1001, thereby preventing excessive solder liquid from adhering to the local area of ​​the finishing wheel 1004.

[0031] The scraper 1005 has a built-in heating element. When the solidified solder on the scraper 1005 needs to be cleaned, the scraper 1005 can be heated by the heating element to melt the solder, making it easier to clean.

[0032] Among them, a cleaning brush 9 is installed on the side of the mounting frame 8 close to the rotation direction of the welding head 7. The cleaning brush 9 contacts the surface of the round tube. When the welding head 7 rotates around the round tube, the cleaning brush 9 brushes away impurities at the part of the round tube that is about to be welded, thereby improving the welding quality.

[0033] Working principle: After the staff puts the round tube into the operation port 101, the air pump 11 is used to inflate the air cavity 102, so that the air pressure inside the air cavity 102 increases, so that the round tube is clamped and fixed by the elastic ring belt 2, and because the elastic ring belt 2 is in close contact with the surface of the round tube, the smoke generated during welding can be prevented from overflowing the welding box 1; then, the driving motor 13 is used to drive the first transmission gear 5 to rotate, and the first transmission gear 5 drives the movable ring 3 to rotate through the transmission gear block 4, thereby driving the welding head 7 to rotate, and the round tube is welded for one circle without rotating the round tube; and in the process of the welding head 7 rotating around the round tube, the cleaning brush 9 brushes away impurities at the part of the round tube that is about to be welded; in addition, in the process of the welding head 7 rotating around the round tube, the friction wheel 10 is used to remove impurities at the part of the round tube that is about to be welded. The friction force between 01 and the round tube causes the friction wheel 1001 to rotate, and the second transmission gear 1002 and the third transmission gear 1003 cooperate to drive the finishing wheel 1004 to rotate, and the finishing wheel 1004 is used to finish the welding part of the round tube. The excess welding liquid adheres to the surface of the finishing wheel 1004, and is scraped off by the scraper 1005 as the finishing wheel 1004 rotates to the scraper 1005, thereby ensuring the stable finishing effect of the finishing wheel 1004; during the welding process, the fume suction device 12 is used to absorb the fume generated during the welding process, and the harmful substances in the fume are filtered through the internal filtering structure. When it is necessary to clean the solidified solder on the scraper 1005, the scraper 1005 can be heated by the heating element, so that the solder can be cleaned after it is melted.

[0034] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
