Description

Technical Field

[0001] The utility model relates to the technical field of pressure swing adsorption nitrogen generators, in particular to a high-efficiency unit type pressure swing adsorption nitrogen generator. Background Technique

[0002] The pressure swing adsorption nitrogen generator uses air as raw material and high-quality carbon molecular sieve as adsorbent. By applying the pressure swing adsorption principle and using the molecular sieve filled with micropores, it selectively adsorbs air to achieve the purpose of oxygen-nitrogen separation.

[0003] For example, in the utility model "A High-Efficiency Unit Type Pressure Swing Adsorption Nitrogen Generator" with the publication number "CN219149699U", the end cover of the machine body is fixed through a rotating block. When the internal sieve plate needs to be replaced, the rotating block can be rotated to remove the cover, and then the internal limit block can be removed. The sieve plates can be removed from the limit posts respectively for replacement. The replacement of the internal sieve plate is convenient, ensuring the screening effect of the sieve plate. However, during the implementation of this patent, the gas cannot be pre-purified, and impurities and dust in the gas are likely to adhere to the carbon molecular sieve plate, thus affecting the nitrogen production process. Moreover, during the nitrogen production process, the device cannot split the gas, causing the gas to be concentrated and blown to a local position of the carbon molecular sieve plate, and the carbon molecular sieve plate cannot be fully utilized. Therefore, the research and development of a new high-efficiency unit type pressure swing adsorption nitrogen generator have received more and more attention from researchers.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present invention: a high-efficiency unit type pressure swing adsorption nitrogen generator, which includes a purification chamber 1, a shunt chamber 9, and a nitrogen production tank 16. One end of the nitrogen production tank 16 is installed with a purification chamber 1, and an intake pipe 4 is installed at the middle position of the end of the purification chamber 1 away from the nitrogen production tank 16. At the top inside the nitrogen production tank 16, a shunt chamber 9 is installed, and a bearing 12 is installed at the middle position of the top inside the shunt chamber 9. An installation pipe 11 is installed inside the bearing 12. At one end of the top of the nitrogen production tank 16 close to the purification chamber 1, an air extraction pump 8 is installed. Here, the model of the air extraction pump 8 can be VCH1028. The input end of the air extraction pump 8 is installed with an air extraction pipe 7 extending into the purification chamber 1, and the output end of the air extraction pump 8 is installed with a diversion pipe 10 extending into the installation pipe 11. At the bottom of both ends inside the nitrogen production tank 16, support plates 27 are installed, and first jacks 19 are provided at the tops of the support plates 27. Carbon molecular sieve plates 21 are installed on the tops of the support plates 27, and second jacks 20 are provided at both ends of the tops of the carbon molecular sieve plates 21. At the bottom of the end of the purification chamber 1 away from the nitrogen production tank 16, a control panel 2 is installed. The output end of the control panel 2 is electrically connected to the input end of the air extraction pump 8 through a wire. At the bottom of the end of the nitrogen production tank 16 away from the purification chamber 1, an air outlet pipe 17 is installed. One side of the shunt chamber 9 is installed with a box door 18, and a handle is installed on the outside of the box door 18 for easy taking and placing of the support plate 27.

[0024] As Figure 1 shown, a screen 3 is installed inside the purification chamber 1. A drying cotton layer 5 is provided at the end of the screen 3 close to the nitrogen production tank 16, and an activated carbon layer 6 is provided at the end of the drying cotton layer 5 away from the screen 3. During use, the dust in the gas can be filtered through the screen 3. The drying cotton layer 5 can adsorb the moisture in the gas, and the activated carbon layer 6 can filter the impurities in the gas, thereby avoiding the attachment of impurities and dust on the carbon molecular sieve plate 21 and preventing the use of the carbon molecular sieve plate 21 from being affected.

[0025] As Figures 1-5As shown in the figure, an L-shaped pipe 13 is installed at the bottom of the installation pipe 11, and a hemispherical flow guide block 14 is installed at the bottom inside the flow distribution bin 9. A plurality of flow distribution pipes 15 are evenly installed inside the hemispherical flow guide block 14. The flow distribution pipes 15 all pass through the flow distribution bin 9 and extend to the outside of the flow distribution bin 9. Gas enters the inside of the installation pipe 11 and is blown out through the L-shaped pipe 13. Due to the reaction force generated by the blowing, the L-shaped pipe 13 can be forced to drive the installation pipe 11 to rotate inside the bearing 12, so that the gas can be blown to different positions inside the flow distribution bin 9. And through the hemispherical flow guide block 14, the gas is guided into different flow distribution pipes 15, so that the gas can be evenly blown to different positions of the carbon molecular sieve plate 21 through the flow distribution pipes 15, which is beneficial to making full use of the carbon molecular sieve plate 21 and improving the nitrogen production efficiency.

[0026] As Figures 1-3 shown in the figure, L-shaped plates 26 are installed on the tops of the support plates 27, and mounting holes 23 are provided at the tops of the L-shaped plates 26. Plug rods 22 are installed inside the mounting holes 23. Connecting plates 24 are installed at the tops of the plug rods 22, and springs 25 are installed at the bottoms of the connecting plates 24. One ends of the springs 25 away from the connecting plates 24 are connected to the L-shaped plates 26. Place the carbon molecular sieve plate 21 on the support plate 27, so that the plug rods 22 are inserted into the second jacks 20 and the first jacks 19, and the carbon molecular sieve plate 21 can be fixed. Take out the plug rods 22 from the second jacks 20, and the carbon molecular sieve plate 21 can be quickly removed from the inside of the flow distribution bin 9, so as to facilitate the staff to quickly replace the carbon molecular sieve plate 21.

[0027] Working principle:

[0028] During installation, the two ends of the carbon molecular sieve plate 21 are respectively placed above the two groups of support plates 27. The elastic action of the spring 25 causes it to pull the connecting plate 24 to move downward. The connecting plate 24 drives the plug rod 22 to move together, and the plug rod 22 can be inserted into the second jack 20 and the first jack 19. By limiting the carbon molecular sieve plate 21 with the plug rod 22, the carbon molecular sieve plate 21 can be prevented from continuing to move, and the carbon molecular sieve plate 21 can be installed inside the nitrogen production box 16.

[0029] During use, connect the device to the power supply, then close the box door 18. The staff can start the air extraction pump 8 through the control panel 2. The air extraction pump 8 extracts air through the air extraction pipe 7, so that the gas is drawn into the purification chamber 1 through the air inlet pipe 4. The dust in the gas is filtered through the screen 3, the moisture in the gas is adsorbed by the drying cotton layer 5, and the impurities in the gas can be filtered through the activated carbon layer 6.

[0030] The filtered gas enters the interior of the installation pipe 11 through the diversion pipe 10, and enters the interior of the L-shaped pipe 13 through the installation pipe 11. By blowing air through the L-shaped pipe 13, due to the reaction force generated by the blowing, the L-shaped pipe 13 can be forced and drive the installation pipe 11 to rotate inside the bearing 12, so that the gas can be blown to different positions inside the shunt chamber 9. And through the hemispherical diversion block 14, the gas is diverted into different shunt pipes 15, and then the gas can be evenly blown to different positions of the carbon molecular sieve plate 21 through the shunt pipes 15, which is beneficial to make full use of the carbon molecular sieve plate 21 and improve the nitrogen production efficiency. The carbon molecular sieve plate 21 selectively adsorbs air to achieve the purpose of oxygen-nitrogen separation;

[0031] After use, the staff can open the box door 18, and then pull the connecting plate 24 upward. The connecting plate 24 drives the insertion rod 22 to move together, and the insertion rod 22 can be taken out from the interior of the second jack 20, so as to release the limit of the insertion rod 22 on the carbon molecular sieve plate 21, making the carbon molecular sieve plate 21 movable. Then the carbon molecular sieve plate 21 can be directly taken out from the interior of the nitrogen production box 16 for cleaning or replacement.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights involved.
