Description

Technical Field

[0001] This utility model relates to the field of oxygen production technology, specifically to a high-efficiency oxygen production device. Background Technology

[0002] There are several methods for producing oxygen, one common method being the use of air separation technology. First, air is compressed to a certain pressure, and then molecular sieves or pressure swing adsorption technology are used to separate oxygen, thus producing oxygen.

[0003] However, existing oxygen generators have some problems. First, to ensure the quality of compression, air and oxygen need to be purified before and after production. Existing devices typically use a filter belt before the compressor to remove impurities from the air; however, to ensure filtration efficiency and quality, the filter belt needs to be replaced after a period of use. Furthermore, existing devices require manual disassembly for periodic replacement, resulting in prolonged maintenance and impacting operational efficiency.

[0004] Secondly, oxygen concentrators generate heat during operation. Existing oxygen concentrators rely solely on heat dissipation grilles on both sides for cooling, resulting in low efficiency. This leads to increased internal temperature, affecting normal operation and oxygen production efficiency. Therefore, we need a more efficient oxygen concentrator to address these issues. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the device is complicated to maintain and has low heat dissipation efficiency, which affects the working efficiency of the equipment. The present invention provides a high-efficiency oxygen generating device.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a high-efficiency oxygen generating device, including an oxygen generating chamber, a compressor installed inside the oxygen generating chamber, a generator connected to the outlet end of the compressor, an oxygen molecular sieve installed inside the generator, a filter frame connected to and cooperating with the compressor on the upper side wall of the oxygen generating chamber, a filter cotton strip installed inside the filter frame, an air inlet pipe connected to and cooperating with the filter frame on the upper part of the oxygen generating chamber, a partition plate fixed inside the oxygen generating chamber, the compressor and the generator located on the top surface of the partition plate, and a first fixing frame fixed on the top surface of the filter frame. A release rod is rotatably mounted inside the first fixed frame. A second fixed frame is fixedly mounted on the bottom surface of the filter frame. A winding rod is rotatably mounted inside the second fixed frame. The upper and lower side walls of the filter frame are provided with through holes that communicate with the first and second fixed frames. The filter cotton tape is wound around the release rod. The end of the filter cotton tape passes through the through hole and is fixed to the winding rod. A heat dissipation frame is fixedly mounted on the inner wall of the oxygen generator box near the compressor and generator. A circulating water pipe is provided inside the heat dissipation frame. A coolant tank that matches the circulating water pipe is fixedly mounted on the outer wall of the oxygen generator box. A radiator is provided on the coolant tank.

[0007] As an improvement, a condenser connected to the generator outlet is fixedly mounted on the bottom surface of the partition plate. A dryer is connected to the outlet of the condenser, and a filter is connected to the outlet of the dryer. The filter extends to the outside of the oxygen generator housing and is equipped with an oxygen delivery pipe. The condenser uses refrigerant to lower the temperature of the air, causing the moisture and impurities in it to condense into liquid, which is then discharged through the condenser. The dryer further removes moisture and impurities by absorbing moisture from the air. Finally, the filter further purifies the air by filtering particulate matter and impurities from the air, thus improving the quality of oxygen production.

[0008] As an improvement, the compressor, generator, condenser, dryer and filter are all connected by gas delivery hoses, which are fixed between the components by bolts, facilitating the installation and disassembly of each component.

[0009] As an improvement, the wall of the heat dissipation frame near the compressor and generator is made of a thermally conductive material to improve thermal conductivity and thus improve heat dissipation efficiency.

[0010] As an improvement, a one-way air intake valve is provided in the air intake pipe, and a flow meter is fixedly installed at one end of the air intake pipe inside the filter frame. The one-way air intake valve prevents backflow, and the flow meter can be set to adjust the speed of air entering, thereby ensuring filtration efficiency and quality.

[0011] As an improvement, a set of sealing grooves are symmetrically arranged inside the filter frame, closely adhering to the outer walls of both sides of the filter cotton strip. The filter cotton strip extends into the sealing grooves, and a sealing strip is provided on the inner wall of the through hole, closely adhering to the filter cotton strip. This can effectively seal the filter cotton strip, allowing air to pass through the filter cotton strip for filtration.

[0012] As an improvement, both the first and second fixed frames are hinged and connected to a sealing cover, and the oxygen generator box is hinged and connected to a maintenance cover, which facilitates maintenance operations inside the oxygen generator box. The sealing cover also facilitates the replacement of the filter cotton roll.

[0013] As an improvement, the outer wall of the oxygen generator box is equipped with a storage basket and a touch control panel, and the bottom surface of the oxygen generator box is equipped with multiple self-locking casters to improve the ease of use of the device.

[0014] The advantages of this utility model compared with the prior art are: the automatic replacement of the filter cotton belt is achieved by the cooperation of the set winding rod and release rod, thereby reducing the maintenance time and cost of the equipment and improving the working efficiency of the equipment;

[0015] The use of circulating water pipes and coolant enables efficient heat dissipation within the oxygen generator chamber, ensuring the working efficiency of the oxygen generator components and improving the overall oxygen generation efficiency of the equipment. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1

[0025] Combined with appendix Figure 1-3As shown in Figure 5, a high-efficiency oxygen generator includes an oxygen generator housing 1. The outer wall of the oxygen generator housing 1 is provided with a storage basket 26 and a touch control panel 27. Multiple self-locking casters 28 are rotatably mounted on the bottom surface of the oxygen generator housing 1. A compressor 2 is installed inside the oxygen generator housing 1. A generator 3 is connected to the outlet end of the compressor 2. An oxygen molecular sieve is installed inside the generator 3. A filter frame 4, which communicates with the compressor 2, is provided on the upper side wall of the oxygen generator housing 1. A filter cotton strip 5 is installed inside the filter frame 4. An air inlet pipe 6, which communicates with the filter frame 4, is connected to the oxygen generator housing 1. A one-way air inlet valve 20 is installed inside the air inlet pipe 6. An internal partition plate 7 is fixedly installed. The compressor 2 and generator 3 are located on the top surface of the partition plate 7. The air inlet pipe 6 is located inside the filter frame 4 and one end is fixedly equipped with a flow meter 21. The bottom surface of the partition plate 7 is fixedly equipped with a condenser 16 connected to the outlet end of the generator 3. The outlet end of the condenser 16 is connected to a dryer 17. The outlet end of the dryer 17 is connected to a filter 18. The filter 18 extends to the outside of the oxygen generating box 1 and is equipped with an oxygen delivery pipe 19. The compressor 2, generator 3, condenser 16, dryer 17 and filter 18 are all connected by air delivery hoses. The air delivery hoses are fixed between the various components by bolts.

[0026] With the above structure, the oxygen generator 1 is first moved to the usage position by pushing the self-locking casters 28. Then, the one-way air intake valve 20 in the air intake pipe 6 is opened, and air enters the oxygen generator 1 through the air intake pipe 6. During the air intake process, the air intake volume is controlled by the touch control panel 27 in conjunction with the flow meter 21. The gas first passes through the filter cotton strip 5 in the filter frame 4 and then enters the compressor 2. The compressor 2 compresses the air to a certain pressure, and then the oxygen is separated by the oxygen molecular sieve in the generator 3. The condenser 16 uses refrigerant to lower the temperature of the air, causing the moisture and impurities in it to condense into liquid, and then the liquid is discharged through the condenser 16. The dryer 17 absorbs the moisture in the air to further remove moisture and impurities. The filter 18 finally filters the particulate matter and impurities in the air to further purify the air. Finally, the high-quality oxygen obtained is taken out for use through the oxygen delivery pipe 19. If necessary, the gas delivery hose is disassembled and each component is inspected.

[0027] Example 2

[0028] Based on Example 1, combined with Appendix Figure 4 and 6As shown, a first fixing frame 8 is fixedly provided on the top surface of the filter frame 4, and a release rod 9 is rotatably provided inside the first fixing frame 8. A second fixing frame 10 is fixedly provided on the bottom surface of the filter frame 4, and a winding rod 11 is rotatably provided inside the second fixing frame 10. The upper and lower side walls of the filter frame 4 are provided with through holes 12 that cooperate with and communicate with the first fixing frame 8 and the second fixing frame 10. The filter cotton strip 5 is wound around the release rod 9. The end of the filter cotton strip 5 passes through the through hole 12 and is fixed to the winding rod 11. A set of sealing grooves 22 that are tightly attached to the outer walls of both sides of the filter cotton strip 5 are symmetrically provided inside the filter frame 4. The filter cotton strip 5 extends into the sealing grooves 22. A sealing strip 23 that is tightly attached to the filter cotton strip 5 is provided on the inner wall of the through hole 12. Sealing cover plates 24 are hinged and connected to both the first fixing frame 8 and the second fixing frame 10. A maintenance cover plate 25 is hinged and connected to the oxygen generator box 1.

[0029] With the above structure, the motor is periodically turned on to drive the release rod 9 and the winding rod 11 to rotate in coordination. This causes the release rod 9 to release the filter cotton belt 5, and the winding rod 11 to wind up the filter cotton belt 5. The new filter cotton belt 5 reaches the sealing groove 22 in the filter frame 4, and works with the air inlet pipe 6 to perform air pretreatment. The sealing strip 23 and the sealing groove 22 seal the filter cotton belt 5. After all the filter cotton belt 5 on the release rod 9 has been used, the maintenance cover 25 and the sealing cover 24 are opened to remove the old filter cotton belt 5 roll and wind up the new filter cotton belt 5 for convenient subsequent use.

[0030] The oxygen generator box 1 has a heat dissipation frame 13 fixedly installed on the inner wall near the compressor 2 and generator 3. The side wall of the heat dissipation frame 13 near the compressor 2 and generator 3 is made of heat-conducting material. A circulating water pipe 14 is installed inside the heat dissipation frame 13. A coolant tank 15 is fixedly installed on the outer wall of the oxygen generator box 1 to cooperate with the circulating water pipe 14. A radiator is installed on the coolant tank 15.

[0031] With the above structure, when the mechanism inside the oxygen generator box 1 is working, the circulating water pump in the radiator and coolant tank 15 is turned on, so that the cooled coolant circulates and absorbs the heat inside the oxygen generator box 1, achieving efficient heat dissipation and ensuring the efficient operation of the oxygen generator components.

[0032] In practical implementation, the oxygen generator 1 is first moved to the working position by the self-locking casters 28. Then, the one-way air intake valve 20 in the air intake pipe 6 is opened, and air enters the oxygen generator 1 through the air intake pipe 6. During the air intake process, the air intake volume is controlled by the touch control panel 27 in conjunction with the flow meter 21. The gas is first filtered through the filter cotton belt 5 in the filter frame 4 and then enters the compressor 2. The compressor 2 compresses the air to a certain pressure, and then the oxygen is separated by the oxygen molecular sieve in the generator 3. The condenser 16 uses refrigerant to reduce the pressure. The low air temperature causes the moisture and impurities in it to condense into liquid, which is then discharged through the condenser 16. The dryer 17 further removes moisture and impurities by absorbing moisture from the air. The filter 18 further purifies the air by filtering particulate matter and impurities. The high-quality oxygen obtained is then taken out for use through the oxygen delivery pipe 19. When the mechanism inside the oxygen generator 1 is working, the circulating water pump in the radiator and coolant tank 15 is turned on, so that the cooled coolant circulates and absorbs the heat inside the oxygen generator 1, achieving efficient heat dissipation and ensuring the efficient operation of the oxygen generator components.

[0033] The motor is periodically turned on to drive the release rod 9 and the winding rod 11 to rotate in coordination. This causes the release rod 9 to release the filter cotton belt 5, and the winding rod 11 to wind up the filter cotton belt 5. The new filter cotton belt 5 reaches the sealing groove 22 inside the filter frame 4, where it works with the air intake pipe 6 to perform air pretreatment. The sealing strip 23 and the sealing groove 22 seal the filter cotton belt 5. After all the filter cotton belt 5 on the release rod 9 has been used, the maintenance cover 25 and the sealing cover 24 are opened to remove the old roll of filter cotton belt 5 and wind up the new roll of filter cotton belt 5. If necessary, the air supply hose is disassembled and each component is inspected for maintenance to facilitate subsequent use.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
