Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, and in particular to a modular adsorption oxygen generator that is easy to disassemble and install. Background Technology

[0002] The core principle of an adsorption oxygen generator is to utilize the selective adsorption difference of molecular sieves on nitrogen and oxygen in the air, and to separate and purify oxygen through periodic pressure changes.

[0003] Adsorption-type oxygen generators typically use zeolite molecular sieves, which have a porous structure with pore sizes close to the diameter of nitrogen molecules, while oxygen molecules are smaller. Under pressure, nitrogen molecules are captured by the micropores of the molecular sieve, while most oxygen molecules, due to their smaller diameter, can pass through. When the pressure is reduced, the adsorbed nitrogen is desorbed from the molecular sieve, restoring its adsorption capacity and allowing for recycling.

[0004] Because the performance of molecular sieves gradually declines and becomes ineffective over time, they can no longer efficiently separate high concentrations of oxygen. Therefore, it is necessary to replace the molecular sieves in the adsorption tower regularly.

[0005] Currently, adsorption oxygen generators typically have detachable side plates to facilitate the replacement of the molecular sieve in the adsorption tower. The adsorption tower is replaced after the side plate is removed. However, due to the limited cavity size of the adsorption oxygen generator, other equipment may be accidentally bumped during the disassembly of the adsorption tower, affecting the disassembly efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a modular adsorption oxygen generator that is easy to disassemble and install. By rotating the lifting screw through the set lifting assembly, the lifting plate can be moved upward, thereby driving the adsorption tower upward. Since the molecular sieve of the adsorption tower needs to be replaced regularly, the adsorption tower can be easily operated, making the operation more convenient and avoiding cross-interference with the equipment in the lower chamber, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular adsorption oxygen generator that is easy to disassemble and install, including an oxygen generator housing assembly, a lifting assembly is provided inside the oxygen generator housing assembly, and a fixing assembly is provided on the top of the lifting assembly;

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By rotating the lifting screw through the set lifting components, the lifting plate can be moved upward, thereby driving the adsorption tower upward.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A modular adsorption oxygen generator that is easy to disassemble and install includes an oxygen generator housing assembly 1, a lifting assembly 2 is provided inside the oxygen generator housing assembly 1, and a fixing assembly 3 is provided on the top of the lifting assembly 2.

[0029] The oxygen generator housing assembly 1 includes an outer shell 101, inside which a first molecular adsorption tower 7 is provided, a gas storage tank 8 is connected to one side of the first molecular adsorption tower 7, and a second molecular adsorption tower 9 is connected to one side of the gas storage tank 8.

[0030] The lifting assembly 2 includes a lifting plate 204 that is slidably disposed inside the outer casing 101. The lifting plate 204 is used to place the first molecular adsorption tower 7, the gas storage tank 8, and the second molecular adsorption tower 9. A lifting screw 201 is threadedly connected to the front side of the interior of the lifting plate 204.

[0031] The lifting assembly 2 also includes a guide rod 202 that runs through the rear side of the lifting plate 204, and a fixed support plate 203 is provided at the bottom of the lifting screw 201 and the guide rod 202, and the fixed support plate 203 is fixed to the front and rear sides of the outer shell 101.

[0032] The fixing component 3 includes: fixing posts 303 fixed to the four corners of the top of the lifting plate 204, a sealing top plate 301 is provided on the top of the fixing post 303, and fixing holes 304 are provided at the four corners of the sealing top plate 301, and fixing screws 302 that are threadedly connected to the fixing post 303 pass through the inside of the fixing holes 304.

[0033] By adopting the above technical solution, when the molecular sieve needs to be replaced, the lifting screw 201 can be rotated, and the lifting plate 204 on the lifting screw 201 moves axially along the lifting screw 201. At this time, the lifting plate 204 drives the first molecular adsorption tower 7, the second molecular adsorption tower 9, and the gas storage tank 8 to move upward. Then, by rotating the fixing screw 302, the sealing top plate 301 can be removed. Through the set lifting assembly 2, rotating the lifting screw 201 can move the lifting plate 204 upward, thereby driving the adsorption tower to move upward. Since the adsorption tower needs to replace the molecular sieve regularly, the adsorption tower can be operated conveniently at this time, making the operation more convenient and avoiding cross-interference with the equipment in the lower cavity.

[0034] Specifically, such as Figure 4 As shown, the oxygen generator housing assembly 1 also includes: a limiting block 102 disposed at the bottom of the lifting plate 204, the limiting block 102 being integrally formed with the outer shell 101, and the oxygen generator housing assembly 1 also includes: an installation groove 103 opened at the top of the outer shell 101, the installation groove 103 being adapted to the size of the sealing top plate 301.

[0035] A connecting pipe 10 is provided between the first molecular adsorption tower 7 and the second molecular adsorption tower 9 and the gas storage tank 8. An outlet pipe 11 is fixed to the side of the gas storage tank 8. A filter box 4 is provided below the lifting plate 204. A compressor 5 is connected to one side of the filter box 4. An output pipe 6 is connected to the output end of the compressor 5. A solenoid valve 12 is provided on the output pipe 6. The length of the output pipe 6 is reserved so as not to affect the upward movement of the first molecular adsorption tower 7, the second molecular adsorption tower 9 and the gas storage tank 8.

[0036] By adopting the above technical solution, the limiting block 102 is used to support the lifting plate 204. When the compressor 5 is working, the external air is filtered through the filter box 4 and then enters the compressor 5. The compressed gas alternately enters the first molecular adsorption tower 7 and the second molecular adsorption tower 9 through the solenoid valve 12 on the output pipe 6. After the air is pressurized to 0.3-0.5MPa by the compressor 5, it enters the first molecular adsorption tower 7. Under high pressure, the molecular sieve in the first molecular adsorption tower 7 preferentially adsorbs nitrogen, and the oxygen concentration in the remaining gas increases. The oxygen-enriched gas flows out from the top of the first molecular adsorption tower 7 and enters the gas storage tank 8. When the first molecular adsorption tower 7 is saturated, the system switches to the second molecular adsorption tower 9 for adsorption. At the same time, the pressure of the first molecular adsorption tower 7 is rapidly reduced to close to atmospheric pressure. Under low pressure, the nitrogen adsorbed in the first molecular adsorption tower 7 is released from the molecular sieve. The first molecular adsorption tower 7 is equipped with a waste gas discharge pipe with a valve, which discharges a small amount of waste gas out of the system. After desorption is completed, the first molecular adsorption tower 7 recovers its adsorption capacity and waits for the next cycle. The first molecular adsorption tower 7 and the second molecular adsorption tower 9 alternately perform adsorption and desorption to achieve continuous oxygen production for 24 hours and improve the stability of oxygen production. The outer shell 101 is divided into upper and lower chambers by the lifting plate 204. The upper chamber houses the adsorption tower and the gas storage tank 8, while the lower chamber integrates auxiliary equipment such as the compressor 5 and the filter box 4, forming a three-dimensional structure of "oxygen production above and power below". The heavy equipment such as the compressor 5 is located in the lower chamber, which can lower the center of gravity of the whole machine.

[0037] Working principle: Air is pressurized to 0.3-0.5 MPa by compressor 5 and then enters the first molecular adsorption tower 7. Under high pressure, the molecular sieve in the first molecular adsorption tower 7 preferentially adsorbs nitrogen, increasing the oxygen concentration in the remaining gas. The oxygen-enriched gas flows out from the top of the first molecular adsorption tower 7 and enters the gas storage tank 8. When the first molecular adsorption tower 7 is saturated, the system switches to the second molecular adsorption tower 9 for adsorption. At the same time, the pressure in the first molecular adsorption tower 7 rapidly decreases to near atmospheric pressure. Under low pressure, the adsorbed nitrogen in the first molecular adsorption tower 7 is released from the molecular sieve. The first molecular adsorption tower 7 is equipped with a waste gas discharge pipe, which is equipped with... The valve is set to discharge a small amount of waste gas from the system. After desorption is completed, the first molecular adsorption tower 7 recovers its adsorption capacity and waits for the next cycle. The first molecular adsorption tower 7 and the second molecular adsorption tower 9 alternately perform adsorption and desorption to achieve continuous oxygen production for 24 hours and improve the stability of oxygen production. When it is necessary to replace the molecular sieve, the lifting screw 201 can be rotated. The lifting plate 204 on the lifting screw 201 moves along the axial direction of the lifting screw 201. At this time, the lifting plate 204 drives the first molecular adsorption tower 7, the second molecular adsorption tower 9 and the gas storage tank 8 to move upward. Then, the fixing screw 302 can be rotated to remove the sealing top plate 301.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
