Description

Technical Field

[0001] The utility model belongs to the technical field of nitrogen generator adsorption towers, in particular to a nitrogen generator adsorption tower with an alarm device. Background Art

[0002] Nitrogen production is a novel nitrogen production technology that uses clean compressed air as raw material and carbon molecular sieve as adsorbent. Using the principle of pressure swing adsorption, the microporous carbon molecular sieve selectively adsorbs gas molecules to produce nitrogen. The adsorption tower is a particularly critical piece of equipment in the nitrogen production process.

[0003] In the prior art, a utility model patent with the announcement number CN214059918U discloses an adsorption tower inspection device for a nitrogen generator, including an adsorption tower. A pressure gauge is fixedly connected to the side wall of the adsorption tower. The pressure gauge can monitor the gas pressure in the adsorption tower to prevent the gas pressure from being too high, thereby improving the safety of the device.

[0004] Although the above-mentioned adsorption tower realizes real-time air pressure monitoring through the pressure gauge, the pressure gauge is fixedly connected to the outer wall of the adsorption tower. When the pressure gauge is damaged, the staff needs to forcibly dismantle the pressure gauge. The dismantling process is complicated and troublesome, which reduces the convenience of repairing the pressure gauge. Summary of the Invention

[0022] Through the mutual cooperation of the first connecting member 7 and the second connecting member 8, after the connecting pipe 2 and the docking pipe 3 are docked, the threaded rod 12 drives the sliding block 11 to be pulled out along the sliding groove 10, and rotated along the rotating block 9 by a certain angle, so that the threaded rod 12 is stuck in the groove 19 and is threadedly connected to the threaded rod 12 through the nut 13, and the nut 13 is tightened on the second connecting member 8, thereby realizing the connection and fixation between the connecting pipe 2 and the docking pipe 3. When the air pressure sensor 4 needs to be disassembled, it is only necessary to loosen the nut 13 and rotate the threaded stem by a certain angle through the rotating block 9 to contact the locking fixation between the connecting pipe 2 and the docking pipe 3, thereby realizing the separation of the connecting pipe 2 and the docking pipe 3, thereby completing the disassembly of the air pressure sensor 4.

[0023] Specifically, in this embodiment, two symmetrical return springs 14 are arranged in the sliding groove 10 , one end of the return spring 14 is mounted on the inner wall of the sliding groove 10 , and the other end of the return spring 14 is mounted on the sliding block 11 .

[0024] The reset spring 14 is arranged to stretch the reset spring 14 when the sliding block 11 is pulled out along the sliding groove 10, so that when the sliding block 11 is released, the sliding block 11 is automatically reset by the elastic potential energy of the reset spring 14, and the threaded rod 12 and the nut 13 cooperate with each other, so that when the nut 13 is pressed against the second connecting member 8, the second connecting member 8 and the first connecting member 7 are pressed and fixed, thereby improving the connection stability between the first connecting member 7 and the second connecting member 8.

[0025] Specifically, in this embodiment, limit sliding grooves 15 are provided on both inner walls of the sliding groove 10 , and limit sliding blocks 16 are slidably arranged in the limit sliding grooves 15 . The limit sliding blocks 16 are installed on the sliding block 11 .

[0026] By means of the cooperation between the position-limiting sliding groove 15 and the position-limiting sliding block 16 , the moving direction and the moving range of the sliding block 11 can be limited.

[0027] Specifically, in this embodiment, an insertion end is provided at the end of the docking tube 3 away from the air pressure sensor 4, and the insertion end has the same diameter as the inner wall of the connecting tube 2. Three insertion slots 17 are evenly arranged along the circumferential direction on the inner wall of the connecting tube 2, and three card blocks 18 are evenly arranged along the circumferential direction and adapted to the insertion slots 17 on the outer wall of the insertion end of the docking tube 3.

[0028] By cooperating with the arranged insertion end, the insertion slot 17 and the clamping block 18, the insertion end can be inserted into the inner wall of the connecting tube 2 when docking the connecting tube 2 with the docking tube 3. At this time, the three clamping blocks 18 are inserted into the open ends of the insertion slot 17. When the insertion end is fully inserted into the connecting tube 2, the three clamping blocks 18 are pressed against the inner wall of the insertion slot 17. Since the cross-section of the insertion slot 17 is L-shaped, the docking tube 3 can be rotated so that the three clamping blocks 18 slide into the clamping end of the insertion slot 17, thereby completing the connection between the connecting tube 2 and the docking tube 3. At this time, the first connecting piece 7 on the connecting tube 2 and the second connecting piece 8 on the docking tube 3 are in an aligned state, thereby achieving further fixation between the connecting tube 2 and the docking tube 3.

[0029] Specifically, in this embodiment, a sealing rubber pad is arranged on the contact surface between the butt joint pipe 3 and the connecting pipe 2 .

[0030] The sealing rubber pad is arranged to improve the sealing performance of the connection between the butt joint 3 and the connecting pipe 2.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
