Description

Technical Field

[0001] The utility model relates to the technical field of vehicle welding waste gas treatment, in particular to a waste gas treatment device for welding metal parts of rail vehicles. Background Art

[0002] The welding process of rail vehicle parts releases exhaust gases containing particulate matter and harmful gases, posing a potential threat to the environment and human health. To address this challenge, welding fume extractors are essential. These exhaust treatment devices, specifically designed for welding, effectively remove harmful substances from exhaust gases through high-efficiency filtration technologies such as cartridge filtration and activated carbon adsorption. Their mobile design allows for flexible deployment at welding sites, while their intelligent control system automatically monitors exhaust gas concentration and adjusts purification efficiency to ensure emissions meet environmental standards.

[0003] However, despite the importance of welding fume extractors in rail vehicle welding, their extraction efficiency remains a concern. In some cases, the purifier's filtration system may not be efficient enough to completely remove all hazardous substances, or its structural design may limit sufficient contact between the exhaust gas and the filter media, thereby affecting the purification effect. Furthermore, the purifier's installation location, usage, and maintenance status can also affect its extraction efficiency. If operators fail to wear appropriate protective equipment, such as masks or respirators, during welding, the potential health risks posed by hazardous substances can be exacerbated.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4 shown, what we introduce is an exhaust gas treatment device specially designed for the welding process of metal parts of rail vehicles, which integrates a variety of key components to achieve efficient and flexible operation capabilities. These components include the chassis 1, which serves as a stable foundation for the entire device; the waste gas filter tank 4, which is used to effectively filter harmful gases generated during the welding process; the intake pipe 5 and the exhaust pipe 6, which are respectively responsible for introducing and discharging exhaust gas from the filtration system; and the valve 7, which is used to precisely control the on-off state of the air flow.

[0024] Under the stable support of the chassis 1, multiple waste gas filter tanks 4 are firmly fixed in an optimized "pin" - shaped layout to ensure the maximization of filtration efficiency and space utilization. The intake pipe 5 and the exhaust pipe 6 both adopt a four - way pipe design to facilitate flexible access to multiple exhaust gas sources and smoothly discharge the purified gas. Valves 7 are cleverly set on these pipes, allowing operators to precisely regulate the flow direction and flow rate of the air flow according to actual needs.

[0025] To further enhance the flexibility and applicability of the device, we installed mobile wheels 2 at the four corners of the chassis 1, enabling the entire device to be easily moved to the desired position. Meanwhile, a support frame 3 is also installed above the chassis 1. It adopts a cube design to enhance the structural strength and is tightly connected to the chassis 1 by bolts. At specific positions on the support frame 3, we carefully set up the first fixing frame 11 and the second fixing frame 13, both of which are designed in an "L" shape. This not only facilitates installation and maintenance but also allows for precise positioning of the distance between the air extractor 9 and the welding area by adjusting their relative lengths.

[0026] Multiple first mounting holes 12 are evenly distributed on the first fixing frame 11, and corresponding second mounting holes 14 are provided on the second fixing frame 13. The two are initially fixed by inserting the first fasteners 15 (composed of fastening bolts, fastening nuts, and anti-slip gaskets). Subsequently, the connection between the two is further strengthened using the second fasteners 16 to ensure the stability and reliability of the air extractor 9 during operation. In addition, the first fixing frame 11 is directly welded to the housing of the air extractor 9, thus achieving a firm connection between the air extractor 9 and the support frame 3.

[0027] Both the first mounting holes 12 and the second mounting holes 14 adopt the design principle of equidistant distribution. This not only facilitates precise alignment during installation and debugging but also makes the adjustment of the distance between the air extractor 9 and the support frame 3 more flexible and convenient. By simply adjusting the relative positions of the first fixing frame 11 and the second fixing frame 13 and re-tightening the fasteners, operators can easily adapt to the changing requirements in different welding scenarios.

[0028] This waste gas treatment device for welding metal parts of rail vehicles, with its efficient and flexible design concept and fine manufacturing process, not only ensures the safety of the welding operation environment but also greatly improves the work efficiency and operation quality.

[0029] Working process: The device takes the chassis 1 as a solid foundation to firmly support the entire system. The waste gas generated during the welding process is guided to the waste gas filter tank 4 through the carefully designed intake pipe 5. These waste gas filter tanks 4 are arranged in an optimized "pin" shape layout to maximize the filtration efficiency and space utilization. The waste gas undergoes efficient filtration in the tank to remove harmful gas components and then is smoothly discharged through the exhaust pipe 6 with a four-way design, and the purified gas is safely released.

[0030] To ensure precise control of airflow, valves 7 are installed on both the intake and exhaust ducts 6, allowing the operator to flexibly adjust the direction and volume of airflow according to actual needs. The device is also equipped with wheels 2, allowing for easy movement of the entire unit to the desired location, enhancing its flexibility. The support frame 3 features a reinforced cubic structure and is tightly bolted to the base frame 1. The "L"-shaped first and second mounting brackets 11, 13 mounted on it not only facilitate installation and maintenance but also ensure the optimal distance between the vacuum pump 9 and the welding area through fine adjustment.

[0031] First mounting holes 12 on first mounting bracket 11 and second mounting holes 14 on second mounting bracket 13 are equidistantly spaced and initially secured with first fasteners 15 (consisting of fastening bolts, fastening nuts, and anti-slip washers). Second fasteners 16 further reinforce the connection, ensuring stable and reliable operation of vacuum pump 9. Furthermore, first mounting bracket 11 is directly welded to the vacuum pump 9 housing, enhancing the overall structural stability.

[0032] By adjusting the relative position of the mounting bracket and re-tightening the fasteners, operators can easily adapt to the changing demands of different welding scenarios. With its efficient and flexible design and sophisticated manufacturing process, this exhaust gas treatment device significantly improves work efficiency and quality while ensuring a safe welding environment.
