Description

Technical Field

[0001] The utility model relates to the technical field of pressure swing adsorption nitrogen making equipment, in particular to a tube bundle type pressure swing adsorption nitrogen making equipment. Background Art

[0002] Pressure swing adsorption atmosphere making equipment is a device that uses carbon molecular sieve as adsorbent and uses the principle of pressure swing adsorption to obtain atmosphere. Under a certain pressure, the purpose of separating air is achieved by using the different diffusion rates of oxygen and ammonia in the pores of the carbon molecular sieve. If the nitrogen generator is used for too long, the quality of the carbon molecular sieve will deteriorate, and the purity of the nitrogen produced will be low, so the carbon molecular sieve needs to be replaced and the purity can be restored. A Chinese patent discloses a bundle-type pressure swing adsorption nitrogen making equipment (authorization announcement number CN219701510U), which discloses a bundle-type pressure swing adsorption nitrogen making equipment, and relates to the technical field of pressure swing adsorption nitrogen making equipment, including a nitrogen generator housing, a nitrogen generator upper cover is provided on the top of the nitrogen generator housing, and the nitrogen generator housing and the nitrogen generator upper cover are fixedly connected by a locking assembly, the locking assembly includes a base and a fixed block, and the base is fixedly connected to the outer wall of the nitrogen generator housing by bolts, the outer wall of the base is fixedly installed with a connecting rod, one end of the fixed block is fixedly installed with a positioning block, and one end of the positioning block is provided with a hole. The utility model drives the positioning block to rotate by rotating the pull ring so that the connecting rod is fixed to the inner wall of the positioning block and cannot shake, which solves the problem of troublesome disassembly and assembly of multiple sets of threaded connections on the nitrogen generator, so that the nitrogen generator shell and the upper cover can be quickly connected. Through the setting of the grooves and the horizontal lines of the holes echoing each other, the connecting rod can be quickly locked by observing the angle of the grooves, thereby improving work efficiency. This patented technology solves the problem that when the existing equipment replaces the carbon molecules in the nitrogen generator, it is necessary to open the upper cover on the top of the nitrogen generator first, but multiple sets of threaded connections are used between the upper cover and the shell, which is troublesome to disassemble and assemble, not only wasting time but also reducing work efficiency.

[0003] However, in the prior art, it takes a long time to disassemble the nitrogen generator and replace the carbon molecule raw material, which reduces the working efficiency of the nitrogen generator.

[0039] According to the above embodiments, the working principle of the present invention is:

[0040] The nitrogen generator closed structure 1 cooperates with the nitrogen generator barrel replacement structure 2 to form a sealed nitrogen generator body;

[0041] When replacing the built-in carbon molecule raw material through the nitrogen generator barrel replacement structure 2, first remove the sealing positioning ring 107 inside the sealing ring groove 207 so that the nitrogen generator docking barrel 206 can be moved;

[0042] After the servo motor 204 is started, the servo motor 204 is started and rotates to drive the worm 203 to rotate, and the worm 203 rotates to engage the worm gear 202, so that the worm gear 202 drives the replacement ring adjustment rod 201 to turn horizontally by 180 degrees, so that the nitrogen generator docking tube 206 with the carbon molecule raw material after use is moved out from between the bottom closed cover body 102 and the top closed cover body 104, and the new carbon molecule raw material is moved to between the closed cover body 102 and the top closed cover body 104.
