[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-5 As shown, this utility model provides a technical solution: a nitrogen delivery pipeline for a large nitrogen generator, including a control cylinder 1, with gas delivery pipes 2 connected to both the top and bottom of the control cylinder 1, a cap 3 threadedly installed on one side of the top of the control cylinder 1, a protective cover 4 connected to the top of the control cylinder 1, a motor 22 fixedly installed on the top of the protective cover 4, a secondary gear 23 rotatably connected to the top of the control cylinder 1, the output shaft of the motor 22 connected to the secondary gear 23, and the motor 22 drives the secondary gear 23 to cause the two connecting pipes 13 to rotate symmetrically around the axis of the rotating rod 5, thereby realizing the interchange of the positions of the two connecting pipes 13, so as to complete the rapid switching of the gas delivery path and the switching of the maintenance position in a short time, and shorten the downtime.

[0015] Inside the control cylinder 1, a rotating rod 5 is rotatably connected via a bearing. A fixed plate 6 is connected to the rotating rod 5. One end of the rotating rod 5 is connected to a main gear 7, which meshes with a secondary gear 23. Both the main gear 7 and the secondary gear 23 are housed within a protective cover 4. A sleeve 14 is inserted into the end of the air supply pipe 2 and comes into close contact with it. The protective cover 4 covers and protects the main gear 7 and the secondary gear 23, reducing direct contact between them and the outside world. The close contact between the sleeve 14 and the end of the air supply pipe 2 improves the sealing of the insertion connection.

[0016] Connecting rings 8 are connected to both sides of the rotating rod 5. A guide groove 9 is provided on the fixed plate 6. The fixed plate 6 is slidably connected to the movable plate 10 through the guide groove 9. An electric push rod 11 is fixedly installed on the fixed plate 6. An inclined groove 12 is provided on the movable plate 10. The movable end of the electric push rod 11 is connected to the movable plate 10. Multiple sliding grooves 25 are provided on the fixed plate 6. The fixed rod 15 slides in the inclined groove 12 and the sliding groove 25. Through the extension and retraction of the electric push rod 11, the movable plate 10 is driven to move horizontally back and forth along the guide groove 9. This allows the inclined groove 12 to move with the movable plate 10 and push the fixed rod 15, causing the insert 14 to slide up and down at the end of the connecting pipe 13, thereby completing the docking or disengagement of the insert 14 with the end of the gas transmission pipe 2.

[0017] A connecting tube 13 is connected to the connecting ring 8. Sleeves 14 are slidably connected to both ends of the connecting tube 13. Fixing rods 15 are connected to both sides of the sleeves 14. A groove 16 is provided on the sleeves 14 above the connecting tube 13. A filter cartridge 17 is inserted into the connecting tube 13. A metal retaining ring 24 is connected above the filter cartridge 17. The metal retaining ring 24 is inserted into the groove 16. The magnetic plate 21 is attracted to the metal retaining ring 24. Through the attraction between the magnetic plate 21 and the metal retaining ring 24, the filter cartridge 17 can be quickly connected to the cover 3. Thus, the filter cartridge 17 can be disassembled and removed by twisting the cover 3. The operation is simple and convenient.

[0018] A handle 18 is slidably connected to the cover 3, and a fixing ring 19 is connected to the handle 18. Springs 20 are sleeved at both ends of the handle 18. The end of the handle 18 passes through the cover 3 and is connected to a magnetic plate 21. The fixing ring 19 slides inside the cover 3. One end of the spring 20 is connected to the fixing ring 19, and the other end of the spring 20 is connected to the inner wall of the cover 3. When the handle 18 is pressed down, the fixing ring 19 will compress the spring 20, and then the spring 20 will rebound to make the handle 18 return to its original position, thus preventing the handle 18 from being misaligned and causing the magnetic plate 21 to accidentally attract the metal retaining ring 24.

[0019] The working principle of this utility model is as follows: By starting the motor 22 to rotate the secondary gear 23, the meshing of the main gear 7 and the secondary gear 23 causes the rotating rod 5 to rotate, thereby causing the positions of the two connecting pipes 13 to be interchanged. Then, the electric push rod 11 is activated to pull the movable plate 10, causing the movable plate 10 to move along the guide groove 9 on the fixed plate 6. During this process, the inclined groove 12 pushes the fixed rod 15, causing the fixed rod 15 to slide along the sliding groove 25 and drive the insert 14 to slide on the connecting pipe 13, causing the insert 14 to be inserted into the end of the gas supply pipe 2, connecting the two gas supply pipes 2. Then, the impurities in the nitrogen are filtered through the filter cartridge 17. After that, the handle 18 on the cover 3 is pressed down, causing the fixed ring 19 to slide inside the cover 3 and compress the spring 20, causing the magnetic suction plate 21 to move down and contact the metal retaining ring 24, thereby completing the adsorption connection. Finally, the cover 3 is screwed off by the handle 18 to remove the cover 3 that is threaded to the control cylinder 1, so that the staff can pull out the filter cartridge 17 to complete the disassembly.
