Description

Technical Field

[0001] This utility model relates to the field of argon recovery technology, and in particular to an argon recovery device. Background Technology

[0002] In welding, such as when welding metals like stainless steel, aluminum, and magnesium, argon gas can form a tight "protective shield" in the welding area, isolating oxygen and nitrogen, preventing the metal from oxidizing at high temperatures and forming nitrides, avoiding defects such as porosity, cracks, and embrittlement in the weld, improving welding quality, and meeting the needs of industries with high welding quality requirements, such as aerospace and automobile manufacturing.

[0003] During deep purification, the recovered gas first enters the catalytic deoxygenator. Under the action of the catalyst, a trace amount of hydrogen is introduced to react with oxygen to generate water and remove it. Then it enters the PSA pressure swing adsorption tower, where molecular sieves adsorb impurities such as nitrogen.

[0004] In existing technologies, the disassembly and assembly processes for argon recovery are cumbersome and slow, which significantly increases the duration of argon recovery interruptions due to maintenance. This makes it difficult to ensure a continuous supply of argon, resulting in production losses due to downtime and affecting the stable delivery of argon to users. The troubleshooting and component replacement processes are complex, increasing the difficulty of operation for maintenance personnel, delaying maintenance progress, and exacerbating the waste of argon emissions. Therefore, an argon recovery device is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an argon gas recovery device, including a base plate 1. An operating box 2 is fixedly connected to the top of the base plate 1. The base plate 1 ensures that all structures are on the same reference plane, maintains the overall stability of the device, and prevents components from shifting due to uneven force. A connecting cover 3 is slidably connected to the rear side of the operating box 2. The bottom of the operating box 2 is fixed to the top of the base plate 1, forming a closed space to avoid the influence of the external environment and limit the installation and movement range of the internal components. The outside of the rotating ring 6 is rotatably connected to the inside of the connecting cover 3. The connecting cover 3 protects the internal components and facilitates the inspection and maintenance of the internal structure of the operating box 2 when opened. The inside of the connecting cover 3 is in contact with the outside of the stop block 8. Two rotating columns 4 are slidably connected inside the operating box 2. A fixed plate 5 is slidably connected to the outside of each rotating column 4. A fixed frame 9 is rotatably connected inside the rotating column 4. The rotating ring 6 can be moved by sliding and rotating to adjust the position of the stop block 8 and realize the control of the relevant structure. The outside of the fixed plate 5 is fixedly connected to the inside of the base plate 1.

[0034] The fixed disk 5 guides and limits the rotating column 4, restricting its radial movement and ensuring that the rotating column 4 slides and rotates along a fixed trajectory, maintaining structural stability. The square slider 7 is externally slidably connected to the inside of the fixed disk 5. The square slider 7 changes position under the action of the stop block 8, cooperating with the fixed disk 5 to limit the movement direction of the stop block 8 and ensure that it moves along the set trajectory. Rotating rings 6 are fixedly connected to adjacent sections of the rotating column 4. The rotating rings 6 drive the stop blocks 8 to move through their own rotation and sliding, adjusting the position of the square slider 7 within the fixed disk 5. Multiple stop blocks 8 are slidably connected inside the rotating rings 6. The stop blocks 8 extend and retract under the action of the rotating rings 6, connecting the rotating rings 6 and the square sliders 7, transmitting motion, and... The motion of the rotating ring 6 is converted into the sliding of the square slider 7. The square slider 7 is fixedly connected to the opposite side of the stop block 8. The rotating column 4 is rotatably connected to the fixed frame 9. The fixed frame 9 supports the rotating column 4 and allows the rotating column 4 to slide and rotate relative to the fixed column 10 to meet the motion requirements of the rotating column 4. The fixed column 10 is slidably connected to the outside of the fixed frame 9. The fixed column 10 is connected to the rotating column 4 through the fixed frame 9, and transmits part of the force of the rotating column 4 to the operating box 2, which enhances the stability of the rotating column 4 and limits its range of motion. The adjacent side of the fixed column 10 is fixedly connected to the outside of the operating box 2. The top of the base plate 1 is fixedly connected to a shock-absorbing component for buffering.

[0035] Reference Figure 4 , Figure 5 The vibration damping assembly includes an argon compressor 12, the bottom of which is fixedly connected to the top of the base plate 1. The argon compressor 12 provides an installation position for the mounting bracket 14, the air pump 13, etc., and the vibration generated during its operation is mitigated by the vibration damping assembly. Two mounting brackets 14 are fixedly connected to the top of the argon compressor 12. The connecting cover 3 has multiple slots 11 inside. When the connecting cover 3 is closed, the slots 11 enhance the connection stability with the operating box 2 through a locking action, preventing the connecting cover 3 from accidentally sliding and ensuring a sealing effect. The bottom of plate 15 is fixedly connected to the top of the second fixing frame 14. The baffle 15 guides the sliding column 18 and restricts its movement direction. At the same time, it provides a fixing point for the elastic plate 19 and transmits the force of the elastic plate 19. Dampers 16 are fixedly connected to the adjacent side of the second fixing frame 14. The dampers 16 can reduce the movement speed of the sliding column 18 through their own damping effect, absorb vibration energy, and reduce the vibration impact on the air pump 13. The front side of the damper 16 is fixedly connected to the sliding column 18, and the baffle 15 is slidably connected to the outside of the sliding column 18.

[0036] Two elastic plates 19 are fixedly connected to each adjacent side of the baffle 15. Limiting plates 17 are slidably connected to the outside of each sliding column 18. The limiting plates 17 prevent the sliding column 18 from slipping out of its preset trajectory due to excessive sliding, ensuring the normal operation of the damping components. A buffer plate 20 is fixedly connected to the outside of each sliding column 18. The sliding column 18 transmits the force of the damper 16 and the elastic plates 19 to the buffer plate 20, achieving vibration damping of the air pump 13. The adjacent sides of the elastic plates 19 are fixedly connected to the opposite sides of the buffer plate 20. When the buffer plate 20 is subjected to force and moves, the elastic plates 19 deform and generate elastic force, assisting the damper 16 in absorbing vibration energy. To reduce impact, the bottom of the limiting plate 17 is fixedly connected to the top of the fixing frame 14. The top of the argon compressor 12 is fixedly connected to the air pump 13. The side of the buffer plate 20 is in contact with the outside of the air pump 13. The buffer plate 20 is in direct contact with the air pump 13, and the force transmitted by the sliding column 18 and the elastic plate 19 is applied to the air pump 13 to buffer the impact of vibration on the air pump 13. The top of the base plate 1 is fixedly connected to the argon pipe 21. The argon pipe 21 transports the recovered argon to subsequent equipment or storage devices. It is the channel for argon circulation to ensure that the argon is transported according to the preset path. The right side of the air pump 13 is fixedly connected to the left side of the argon pipe 21.

[0037] Working principle: When the device is working, the base plate 1 provides a stable reference, the operating box 2 forms a closed space, the rotating column 4 slides and rotates in the operating box 2, and is guided and limited by the fixed plate 5, which drives the rotating ring 6 to move. The rotating ring 6 drives multiple stops 8 to extend and retract, so that the square slider 7 slides in the fixed plate 5. The fixed frame 9 cooperates with the fixed column 10 to enhance the stability of the rotating column 4. The stops 8 are engaged and fixed with the connecting cover 3. The connecting cover 3 can be slidably opened and closed for easy maintenance. It is used to complete the recycling of cold box drain liquid, reduce argon emission waste, improve the overall recovery rate of the device, reduce costs, achieve energy saving and emission reduction, cost reduction and efficiency improvement, ensure continuous argon supply, reduce production loss caused by downtime, reduce manpower and time input during maintenance, and avoid component damage caused by improper disassembly, extend the service life of the device, and indirectly reduce equipment maintenance and replacement costs.

[0038] When the vibration damping assembly is working, the argon compressor 12 generates vibration, which is transmitted to the damper 16 and elastic plate 19 through the fixed frame 14. The damper 16 drives the buffer plate 20 through the sliding column 18, and together with the elastic force generated by the deformation of the elastic plate 19, they absorb the vibration energy. The baffle 15 and the limiting plate 17 restrict the trajectory of the sliding column 18. The buffer plate 20 acts directly on the gas pump 13 to reduce vibration. The gas pump 13 delivers argon through the argon pipe 21, realizing stable operation of vibration damping and argon delivery. Vibration damping can reduce the impact of device vibration on the main tower, auxiliary tower bottom and tower top liquid level, avoid excessive liquid level fluctuation due to vibration, ensure the stability of the distillation process, ensure the pressure stability after liquid argon vaporization, avoid argon delivery pressure fluctuation due to vibration, ensure a continuous and stable supply of qualified argon to users, and improve the recovery rate.
