[0002] A high-pressure gas purifier is a device used to clean and remove impurities from gases, particularly those used in high-pressure environments. Its primary function is to ensure that gases meet the required purity standards under high pressure. These devices are commonly used in industrial and scientific research, specifically to ensure that impurities do not interfere with gas quality and performance during gas transportation, storage, and use.

[0003] Currently, the gas delivery pipes of a high-pressure gas purifier (including connecting pipes for delivering gas to the interior of the high-pressure gas purifier and connecting pipes for delivering gas from the interior of the high-pressure gas purifier to the outside) are usually installed on the surface of the high-pressure gas purifier. When the gas delivery pipes installed on the surface of the high-pressure gas purifier are deformed due to collisions with external objects (such as collisions between a transfer cart pushed by staff and the gas delivery pipes on the surface of the high-pressure gas purifier), which affects their use, staff need to cut the gas delivery pipes from the high-pressure gas purifier and then weld new gas delivery pipes to the high-pressure gas purifier. When cutting the gas delivery pipes, there is a risk that the outer wall of the high-pressure gas purifier may be accidentally cut and damaged. When welding the new gas delivery pipes, there is a risk that the welding position of the new gas delivery pipes may be offset, causing damage to the outer wall of the high-pressure gas purifier.

The fixing ring 415 is provided with a push plate 4114. The arrangement of the connecting locking block 4111 and the connecting groove 4113 allows the gas inlet and outlet pipe 2 to be locked to the connecting base 411, thereby connecting the gas inlet and outlet pipe 2 to the purifier tank 1.

[0023] The auxiliary positioning member 42 includes a fixed support frame 421 arranged on the connecting base 411, a first positioning hole 422 opened on the fixing ring 415 and a through hole opened on the inner side of the connecting groove 4113, a positioning rod 4213 is arranged on the inner side of the through hole, a second fixed block 423 is arranged on the fixed support frame 421, a receiving groove 424 is opened in the second fixed block 423, a positioning rod 426 is arranged on the second fixed block 423, one end of the positioning rod 426 is inserted into the first positioning hole 422 on the fixing ring 415, and an inclined mouth 4260 is opened on the end of the positioning rod 426 inserted into the first positioning hole 422, and the other end of the positioning rod 426 is inserted into the receiving groove 424 on the second fixed block 423. A coil spring 425 is provided on the inner side of the accommodating groove 424, and a second limit block 427 is provided on one end of the positioning rod 426 inserted in the accommodating groove 424. One end of the coil spring 425 is connected to the second limit block 427 on the inner side of the accommodating groove 424. Two guide grooves 428 are provided on the second fixed block 423, and the two guide grooves 428 are communicated with the accommodating groove 424. Two push blocks 429 are provided on the second limit block 427, and the two push blocks 429 respectively pass through the two guide grooves 428 on the second fixed block 423 and extend to the outside of the second fixed block 423. A second positioning hole 4210 is provided on the connecting base 411, and the positions of the positioning rod 4213 and the second positioning hole 4210 correspond to each other. One end of the positioning rod 4213 extends to the connecting groove 4113, and the end of the positioning rod 4213 extending to the connecting groove 4113 is mortgaged on the connecting locking block 4111. A steep opening 4215 is provided at the end of the positioning rod 4213 extending to the connecting groove 4113. A cavity 4211 is provided in the first connecting ring 412, and the cavity 4211 is communicated with the through hole. A fixing ring 4214 is provided on the positioning rod 4213, and the fixing ring 4214 is located on the inner side of the cavity 4211. A return spring 4212 is provided on the inner side of the cavity 4211, and one end of the return spring 4212 is connected to the fixing ring 4214 on the inner side of the cavity 4211. The auxiliary positioning member 42 can be used to lock the position of the fixing ring 415, so as to avoid the connection locking block 4111 locked on the inner side of the connection groove 4113 from rotating due to the force exerted on the fixing ring 415, causing the connection locking block 4111 to rotate out from the inner side of the connection groove 4113, thereby causing the lock between the gas inlet and outlet pipe 2 and the purifier tank 1 to be accidentally released.

[0024] The implementation principle of the embodiment of this application is: When the gas inlet and outlet pipe 2 needs to be replaced, the fixing ring 415 is rotated by pushing the push plate 4114. During the rotation of the fixing ring 415, the rotating force of the fixing ring 415 directly acts on the inclined opening 4260 on the positioning plug 426. When the force acting on the inclined opening 4260 reaches a certain value, the positioning plug 426 will move toward the bottom end of the inner side of the accommodating groove 424 on the second fixing block 423. When one end of the positioning plug 426 moves out of the first positioning hole 422, one end of the positioning plug 426 with the inclined opening 4260 is placed on the fixing ring 415. During the rotation of the fixing ring 415, it will drive the first fixing block 4112 on the fixing ring 415 to rotate. A fixing block 4112 drives the connecting lock block 4111 to rotate. When the connecting lock block 4111 is staggered with the positioning rod 4213, the return spring 4212 extends the steep opening 4215 on the positioning rod 4213 to the inner side of the connecting groove 4113 on the first connecting ring 412 through the fixing ring 4214 on the positioning rod 4213. When the connecting lock block 4111 is rotated out from the inner side of the connecting groove 4113 on the first connecting ring 412, the gas inlet and outlet pipe 2 can be pulled out from the connecting base 411 to complete the disassembly of the gas inlet and outlet pipe 2; then a new gas inlet and outlet pipe 2 is placed on one side of the purifier tank 1, and then one end of the gas inlet and outlet pipe 2 is extended to the purifier through the connecting base 411. In the tank 1, the first connecting ring 412 on the gas inlet and outlet pipe 2 is pressed against the connecting base 411, and then the fixing ring 415 is rotated in the opposite direction by the push plate 4114. The fixing ring 415 drives the connecting lock block 4111 to rotate through the first fixing block 4112. When the connecting lock block 4111 is rotated to the inside of the connecting groove 4113 on the first connecting ring 412, the connecting lock block 4111 will be pressed against the steep mouth 4215 on the positioning rod 4213. As the connecting lock block 4111 continues to rotate, the force on the positioning rod 4213 gradually increases. At this time, the positioning rod 4213 is forced to move toward the connecting base 411. As the positioning rod 4213 moves, the fixing ring 421 on the positioning rod 4213 is pressed. The return spring 4212 on the inner side of the cavity 4211 is squeezed, and the end of the positioning rod 4213 away from the connecting locking block 4111 is inserted into the second positioning hole 4210 on the connecting base 411. When the side wall of the connecting locking block 4111 located inside the connecting groove 4113 is attached to the inner wall of the connecting groove 4113, the fixing ring 415 rotates to the end of its stroke. At this time, the positioning rod 426 on the second fixing block 423 corresponds to the first positioning hole 422 on the fixing ring 415, and the positioning rod 426 is pushed by the coil spring 425 to be pushed into the first positioning hole 422 on the fixing ring 415, thereby locking the fixing ring 415 in position.

[0025] Example 2: Reference Figure 2, high-pressure gas purifier, the upper and lower ends of the purifier tank 1 are respectively provided with an upper end cover 5 and a lower end cover 6, the upper and lower end walls of the inner side of the purifier tank 1 are provided with connecting threads 7, the upper end cover 5 and the lower end cover 6 are both provided with threaded columns 8, the upper end cover 5 and the lower end cover 6 are connected to the upper and lower ends of the purifier tank 1 through the threaded columns 8, one end of the threaded column 8 is provided with a sealing head 9, a purifying agent 10 is provided on the inside of the purifier tank 1, and the purifying agent 10 is provided with multiple layers, the lower end surface of the lower end cover 6 is provided with a supporting leg 11, and the upper end cover 5 is provided with a pressure relief valve 12.

[0026] The implementation principle of the embodiment of this application is: When it is necessary to replace the purifying agent 10 inside the purifier tank 1, the upper end cover 5 and the lower end cover 6 are rotated respectively to remove the upper end cover 5 and the lower end cover 6 from the purifier tank 1, and then the purifying agent 10 that needs to be replaced inside the purifier tank 1 is taken out and replaced, and finally the upper end cover 5 and the lower end cover 6 are installed at the upper and lower ends of the purifier tank 1 according to the above method. The upper end cover 5 and the lower end cover 6 can be disassembled by the arrangement of the threaded column 8 and the connecting thread 7, so as to replace the purifying agent 10 inside the traditional purifier tank 1, which requires cutting the upper end cover 5 and the lower end cover 6 from the purifier tank 1 and welding the upper end cover 5 and the lower end cover 6 to the purifier tank 1 after the replacement is completed. This method makes it easy to replace the upper end cover 5 and the lower end cover 6, so that the replacement efficiency of the purifying agent 10 can be improved.

[0027] Working principle of the present invention: When the gas inlet and outlet pipe 2 needs to be replaced, the fixing ring 415 is rotated by pushing the push plate 4114. During the rotation of the fixing ring 415, the rotating force of the fixing ring 415 directly acts on the inclined opening 4260 on the positioning plug 426. When the force acting on the inclined opening 4260 reaches a certain value, the positioning plug 426 will move toward the bottom end of the inner side of the accommodating groove 424 on the second fixing block 423. When one end of the positioning plug 426 moves out of the first positioning hole 422, one end of the positioning plug 426 with the inclined opening 4260 is placed on the fixing ring 415. During the rotation of the fixing ring 415, it will drive the first fixing block 4112 on the fixing ring 415 to rotate. A fixing block 4112 drives the connecting lock block 4111 to rotate. When the connecting lock block 4111 is staggered with the positioning rod 4213, the return spring 4212 extends the steep opening 4215 on the positioning rod 4213 to the inner side of the connecting groove 4113 on the first connecting ring 412 through the fixing ring 4214 on the positioning rod 4213. When the connecting lock block 4111 is rotated out from the inner side of the connecting groove 4113 on the first connecting ring 412, the gas inlet and outlet pipe 2 can be pulled out from the connecting base 411 to complete the disassembly of the gas inlet and outlet pipe 2; then a new gas inlet and outlet pipe 2 is placed on one side of the purifier tank 1, and then one end of the gas inlet and outlet pipe 2 is extended to the purifier through the connecting base 411. In the tank 1, the first connecting ring 412 on the gas inlet and outlet pipe 2 is pressed against the connecting base 411, and then the fixing ring 415 is rotated in the opposite direction by the push plate 4114. The fixing ring 415 drives the connecting lock block 4111 to rotate through the first fixing block 4112. When the connecting lock block 4111 is rotated to the inside of the connecting groove 4113 on the first connecting ring 412, the connecting lock block 4111 will be pressed against the steep mouth 4215 on the positioning rod 4213. As the connecting lock block 4111 continues to rotate, the force on the positioning rod 4213 gradually increases. At this time, the positioning rod 4213 is forced to move toward the connecting base 411. As the positioning rod 4213 moves, the fixing ring 421 on the positioning rod 4213 is pressed. The return spring 4212 on the inner side of the cavity 4211 is squeezed, and the end of the positioning rod 4213 away from the connecting locking block 4111 is inserted into the second positioning hole 4210 on the connecting base 411. When the side wall of the connecting locking block 4111 located inside the connecting groove 4113 is attached to the inner wall of the connecting groove 4113, the fixing ring 415 rotates to the end of its stroke. At this time, the positioning rod 426 on the second fixing block 423 corresponds to the first positioning hole 422 on the fixing ring 415, and the positioning rod 426 is pushed by the coil spring 425 to be pushed into the first positioning hole 422 on the fixing ring 415, thereby locking the fixing ring 415 in position.When the purifying agent 10 inside the purifier tank 1 needs to be replaced, the upper end cover 5 and the lower end cover 6 are rotated respectively to remove the upper end cover 5 and the lower end cover 6 from the purifier tank 1. Then, the purifying agent 10 to be replaced inside the purifier tank 1 is taken out and replaced. Finally, the upper end cover 5 and the lower end cover 6 are installed at the upper and lower ends of the purifier tank 1 according to the above method. The threaded column 8 and the connecting thread 7 make the upper end cover 5 and the lower end cover 6 removable. This replaces the traditional method of cutting the upper end cover 5 and the lower end cover 6 from the purifier tank 1 when replacing the purifying agent 10 inside the purifier tank 1. After the replacement is completed, the upper end cover 5 and the lower end cover 6 are welded to the purifier tank 1. This method makes it easier to replace the upper end cover 5 and the lower end cover 6, thereby improving the replacement efficiency of the purifying agent 10.
