Description

Technical Field

[0002] In the current laser welding process, laser welding machines have been widely used in the manufacturing industry due to their advantages such as high precision, high efficiency, and low heat-affected zone. However, with the popularization of laser welding technology, the problem of exhaust gas generated during the laser welding process has become increasingly prominent. Existing exhaust gas treatment solutions for laser welding machines often involve direct emission or simple filtration using a filter net. Although this can reduce exhaust gas emissions to a certain extent, due to the relatively simple structure of the filter net, the treatment effect is not good, and it is difficult to effectively remove harmful substances in the exhaust gas, posing a potential threat to the environment and the health of operators.

Detailed Description of the Embodiment

[0018] The following further describes the present application in detail with reference to the Figures 1-3 drawings.

[0019] The embodiment of the present application discloses a waste gas processor for a laser welding machine. Refer to Figure 1, including a purifier, which is composed of purifier 1 and purifier 2. On the outer walls on both sides of the purifier, tee pipe 1 and tee pipe 2 are staggered. One end of tee pipe 1 is connected to treatment box 4. On the outer wall of treatment box 4, delivery pipe 3 is fixed. Delivery pipe 3 is connected to the exhaust gas pipe of the laser welding machine to convey the exhaust gas into the interior of treatment box 4. The output end of treatment box 4 is connected to the input end of tee pipe 1. On both tee pipe 1 and tee pipe 2, regulating valves 8 are installed, which can be adjusted unidirectionally or bidirectionally according to requirements, facilitating the centralized treatment of exhaust gas.

[0020] As Figure 2 shown, on the surface of treatment box 4, glass window 5 is fixed, which is convenient for observing the internal treatment situation. Inside treatment box 4, fixing groove 9 is formed. In fixing groove 9, serpentine delivery pipe 10 is provided, facilitating the conveyance of exhaust gas into serpentine delivery pipe 10. Since a group of honeycomb filters 11 are equidistantly distributed in serpentine delivery pipe 10, and the aperture of honeycomb filter 11 gradually decreases from one side to the other side. At this time, large particle impurities in the exhaust gas can be intercepted layer by layer. Inside fixing groove 9, a group of card slots adapted to honeycomb filter 11 are equidistantly formed. One end of honeycomb filter 11 extends outside the card slot and is fixed with clamping block 12, facilitating the disassembly and assembly of honeycomb filter 11 for cleaning.

[0021] As Figure 3 shown, inside both purifier 1 and purifier 2, purification chambers 13 are formed. On the outer walls of both purifier 1 and purifier 2, sealing covers 18 are connected through flanges. Inside the purifier, built-in processor 14 is provided. Along the circumferential direction on the outer surface of built-in processor 14, a number of adsorption ports 15 are equidistantly distributed;

[0022] Inside adsorption port 15, activated carbon adsorption material 16 is provided. By using the strong adsorption property of activated carbon, harmful gases in the exhaust gas are deeply adsorbed. At the center inside built-in processor 14, particulate air filter element 17 is installed. Particulate air filter element 17 serves as the last line of defense to further filter the exhaust gas.

[0023] The implementation principle of the exhaust gas processor of a laser welding machine in the embodiment of this application is as follows: During use, one end of delivery pipe 3 is connected to the exhaust gas pipe on the laser welding machine to convey the exhaust gas into the interior of treatment box 4. The exhaust gas passes through multiple honeycomb filters 11 in serpentine delivery pipe 10 for layer-by-layer circuitous filtration, capable of sequentially removing large particle impurities and soot in the exhaust gas. At the same time, the internal treatment situation can be observed through glass window 5. The treated gas is shunted to purifier 1 and purifier 2 through tee pipe 1 and is sequentially filtered through built-in processor 14. The gas is first deeply adsorbed by activated carbon adsorption material 16 inside adsorption port 15, and then passes through particulate air filter element 17 to finely filter the exhaust gas, ensuring that the exhaust gas discharged into the atmosphere meets the environmental protection standards. Finally, regulating valve 8 is opened, and the gas can be discharged into the atmosphere through tee pipe 2.
