Technical Field
[0001] The utility model relates to the technical field of nitrogen-making adsorption cylinder installation, in particular to a nitrogen-making adsorption cylinder. Background Art
[0002] Pressure swing adsorption nitrogen generator uses high-quality carbon molecular sieve as adsorbent. Under certain mechanical effects, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much greater than that of nitrogen. When adsorption has not reached equilibrium, nitrogen is enriched in the gas phase to form finished nitrogen. Then, it is decompressed to normal pressure, and the adsorbent desorbs oxygen and other impurities to achieve regeneration. It is a widely used nitrogen generator, and the adsorption cylinder is one of the core components of the nitrogen generator.
[0003] The existing nitrogen adsorption cylinder has the following disadvantages during installation and use: the nitrogen adsorption cylinder is one of the supporting components of the nitrogen making equipment, and the nitrogen making equipment also includes a nitrogen buffer. During installation, it needs to be moved to a suitable installation position and connected to the nitrogen buffer pipeline. Due to the large volume of the nitrogen adsorption cylinder, the nitrogen adsorption cylinder cannot be accurately placed at one time, so the connection between the nitrogen adsorption cylinder and the nitrogen buffer cannot be accurately connected, and the position needs to be manually fine-tuned to make the interface connected;
[0004] However, the existing nitrogen buffer is heavy and inconvenient to move manually. Therefore, we propose a nitrogen adsorption cylinder to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-5 A nitrogen-making adsorption cylinder comprises an adsorption cylinder body 1, a nitrogen buffer 2 and a motor 4. The bottom end of the adsorption cylinder body 1 is fixedly connected with a connecting plate 5, and the bottom end of the connecting plate 5 is fixedly connected with a limiting block 14. The surface of the limiting block 14 is sleeved with a rectangular frame 9, and the bottom end of the rectangular frame 9 is fixedly connected with a supporting plate 3. A threaded rod 13 is inserted into the interior of the rectangular frame 9, and the left end of the threaded rod 13 is fixedly connected with a rotating rod 10, and the rotating rod 10 is fixedly connected with the output end of the motor 4.
[0024] Further, see Figure 2 It can be known that the front and rear surfaces of the connecting plate 5 are symmetrically fixedly connected with the fixed frame 6, and the limiting rod 11 is fixedly connected at the center position of the bottom end of the fixed frame 6, and the front and rear surfaces of the limiting rod 11 are in contact with the supporting guard plate 7. During use, the supporting guard plate 7 can limit the limiting rod 11, thereby facilitating the linear movement of the fixed frame 6.
[0025] Further, see Figure 2 It can be known that a rectangular groove is provided at the top of the support guard plate 7, and a roller 12 is installed inside the rectangular groove. A discharge hole is provided at the bottom of the fixed frame 6, and the discharge hole is located above the roller 12. The roller 12 can reduce the friction between the fixed frame 6 and the surface of the support guard plate 7. During use, the lubricating liquid drips through the discharge hole, which can lubricate the roller 12 and assist the movement of the fixed frame 6.
[0026] Further, see Figure 4 and Figure 5 It can be known that the inner wall of the fixed frame 6 is symmetrically fixedly connected with support bars 18, and a second sealing plate 17 is inserted between the support bars 18, and the top of the second sealing plate 17 is fixedly connected with the first sealing plate 16. During use, the second sealing plate 17 is tightly fitted with the first sealing plate 16 and the support bars 18, thereby achieving a sealing effect.
[0027] Further, see Figure 5It can be known that the top end of the first sealing plate 16 is fixedly connected with a pull rod 8, and a return spring 15 is sleeved on the surface of the pull rod 8, the top end of the return spring 15 is fixedly connected to the top inner wall of the fixed frame 6, and the bottom end of the return spring 15 is fixedly connected to the top end of the first sealing plate 16. During use, the elastic deformation of the return spring 15 itself facilitates the pushing of the second sealing plate 17 to reset.
[0028] Further, see Figure 4 It can be seen that a threaded groove is provided on the central surface of the limit block 14, and the threaded rod 13 is inserted into the inside of the threaded groove. The threaded rod 13 and the limit block 14 are threadedly connected. During use, it is convenient to adjust the connecting plate 5 to move left and right, and at the same time, the internal and external threads can play a self-locking function.
[0029] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, when it is necessary to connect the adsorption cylinder body 1 with the interface of the nitrogen buffer 2, the motor 4 is energized through an external power supply, and the output end of the motor 4 rotates to drive the rotating rod 10 to rotate, and the rotating rod 10 rotates to drive the threaded rod 13 to rotate, and the threaded rod 13 rotates to drive the limit block 14 to move on its surface, so as to facilitate the adjustment of the position of the connecting plate 5, so that the interface on the right side of the adsorption cylinder body 1 is close to the interface on the left side of the nitrogen buffer 2, which is convenient for fixed connection;
[0030] Before the fixed frame 6 moves, the staff manually pulls the pull rod 8 upwards, and the pull rod 8 drives the first sealing plate 16 to move upwards, and the first sealing plate 16 drives the second sealing plate 17 to move upwards, and a gap is generated between the second sealing plate 17 and the support bar 18. The lubricating oil drips from the gap to the bottom of the fixed frame 6, and drips to the surface of the roller 12 through the discharge hole at the bottom of the fixed frame 6. When the roller 12 rolls, the lubricating oil is evenly applied on its surface, thereby playing a lubricating role and assisting the movement of the fixed frame 6. When the lubrication is completed, the external force of the pull rod 8 is released, and the reset spring 15 resets and pushes the second sealing plate 17 to seal the support bar 18, and the operation is completed. The above is the entire working principle of the utility model.
[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
