Description

Technical Field

[0001] This utility model specifically relates to the field of medical oxygen generation technology, and more specifically to a medical membrane separation oxygen generator. Background Technology

[0002] A membrane oxygen generator is a device that uses membrane separation technology to extract high-purity oxygen from the air. The core of a membrane oxygen generator is a polymer membrane with special selectivity. Under certain pressure conditions, when air passes through this membrane, due to the differences in size, shape, and interaction with the membrane between oxygen and other gas molecules such as nitrogen, oxygen molecules can preferentially pass through the membrane, while impurity molecules such as nitrogen, carbon dioxide, and water vapor are retained. This achieves the separation of oxygen from other gases, thereby extracting high-purity oxygen.

[0003] However, in practice, it has been noted that membrane separation technology mainly relies on the difference in the permeation rate of gas molecules in the membrane to separate oxygen. Its separation speed and efficiency have certain limitations. In situations where a large amount of oxygen is required, it may not be able to provide enough oxygen in time, requiring a large amount of electrical energy to maintain the long-term operation of multiple oxygen generators to ensure the oxygen supply. Furthermore, when the oxygen separation membrane is damaged, it is necessary to shut down the machine for repair. Since the oxygen separation membrane is generally installed inside the equipment, it takes a lot of time to remove it, affecting normal use. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figure 1-7 This utility model provides a medical membrane separation oxygen generator, including an oil-free compressor station 1. The outlet of the oil-free compressor station 1 is provided with a compressed air pipe 2. The other end of the compressed air pipe 2 is provided with an oxygen separation mechanism. An oxygen delivery pipe 7 is fixedly connected to the end of the oxygen separation mechanism away from the compressed air pipe 2. The other end of the oxygen delivery pipe 7 is connected to an oxygen storage tank 8.

[0028] The oxygen separation mechanism includes an oxygen separation membrane 5 arranged in a ring array. The two ends of the oxygen separation membrane 5 are respectively provided with a flow divider 4 and a hollow gas collection seat 6. The top of the flow divider 4 is fixedly connected with a sealing cover 3, and the flow divider 4 is fixedly connected to the end of the compressed air pipeline 2 through the sealing cover 3.

[0029] In this embodiment, each of the oxygen separation membranes 5 is fixedly connected to two ends of a valve 9, and the two ends of the oxygen separation membrane 5 are respectively connected to the diversion box 4 and the hollow gas collecting seat 6 through the valve 9.

[0030] Furthermore, the diversion box 4 includes a vortex housing 41 fixedly connected to the sealing cover 3. The bottom of the vortex housing 41 is welded with a flange pipe 42 corresponding to the oxygen separation membrane 5, and the end of the flange pipe 42 is fixedly connected to the end of the valve 9 away from the oxygen separation membrane 5.

[0031] Furthermore, an energy conversion component 10 is movably connected in the vortex housing 41. The energy conversion component 10 includes a shaft 101 that passes through the vortex housing 41. One end of the shaft 101 is fixedly connected to a turbine blade 102, and the turbine blade 102 is located in the vortex housing 41.

[0032] More specifically, the vortex housing 41 is also fixedly connected to a conical guide shroud 43 located at the bottom of the turbine blade 102, the shaft 101 passes through the conical guide shroud 43, and a sealing assembly is provided between the conical guide shroud 43 and the shaft 101.

[0033] In this embodiment, the end of the shaft 101 away from the vortex housing 41 is movably connected to the hollow gas collecting seat 6. The hollow gas collecting seat 6 includes a hollow collecting box 61 located below the oxygen separation membrane 5. A flange connecting pipe 63 corresponding to the valve 9 is welded to the top of the hollow collecting box 61, and the end of the valve 9 away from the oxygen separation membrane 5 is fixedly connected to the flange connecting pipe 63.

[0034] In this embodiment, the bottom of the hollow collection box 61 is provided with a support base 62 in a ring array, and the top of the hollow collection box 61 is integrally provided with a central positioning sleeve, and a bearing is interference-fitted in the central positioning sleeve, with the inner ring of the bearing interference-fitted with the end of the shaft 101.

[0035] More specifically, the end of the shaft 101 near the hollow gas collection seat 6 is provided with a generator 103 in a ring array, and the generator 103 is fixedly connected to the hollow gas collection seat 6. A bevel gear 104 that is in transmission cooperation with the generator 103 is also fixedly connected to the shaft 101.

[0036] By adopting the above technical solution, when compressed air passes through the inside of the volute 41, it will drive the turbine blades 102 inside the volute 41 to rotate. The turbine blades 102 convert the potential energy in the compressed air into kinetic energy, and transmit the kinetic energy to the bevel gear 104 through the shaft 101. Through the transmission connection between the generator 103 and the bevel gear 104, multiple generators 103 can work simultaneously to convert kinetic energy into electrical energy to power the oxygen generator, thereby reducing the electrical energy consumed by the oxygen generator when it is working and reducing energy consumption.

[0037] In this embodiment, a driven gear is fixedly connected to the end of the generator 103, and the driven gear meshes with the bevel gear 104. Through the transmission connection between the driven gear and the bevel gear 104, the shaft 101 drives the input shaft of the generator 103 to rotate, thereby converting kinetic energy into electrical energy.

[0038] Furthermore, the outer side of the turbine blade 103 is fixedly connected with blade reinforcing strips 105 in a ring array to reinforce the side of the turbine blade 103 and prevent deformation caused by prolonged compression by compressed air.

[0040] More specifically, the bottom of the hollow collection box 61 is conical, and an oxygen outlet pipe is integrally provided at the center of the bottom of the hollow collection box 61. The end of the oxygen delivery pipe 7 is connected to the inside of the hollow collection box 61 through the oxygen outlet pipe. After being collected by the hollow collection box 61, the oxygen is sent into the oxygen storage tank 8 through the oxygen delivery pipe 7.

[0041] The working principle of this utility model is as follows: During use, firstly, depending on the usage, different numbers of valves 9 are opened. Then, the oil-free compressor station 1 compresses the external air. The compressed air is sent into the volute 41 through the compressed air pipe 2. The compressed air passes through the inner side of the volute 41 from top to bottom, and then is sent to the oxygen separation membrane 5 through the flange pipe 42 for separation. The separated oxygen is concentrated inside the hollow collection box 61 through the flange connection pipe 63, and finally sent to the oxygen storage tank 8 for storage through the oxygen delivery pipe 7. When the compressed air passes through the volute 41, the downward-moving compressed air drives the turbine blades 102 inside the volute 41 to rotate. The turbine blades 102 transfer potential energy... The energy is converted into kinetic energy and output outward through shaft 101. The end of shaft 101 is connected to the driven gear through bevel gear 104, which drives the input shaft of generator 103 to rotate. Generator 103 converts kinetic energy into electrical energy for output. This can be used to power the oxygen generator or other locations, thereby reducing the energy consumption of the oxygen generator during use. When a single oxygen separation membrane 5 becomes blocked or damaged and cannot be used, it can be disassembled and replaced or maintained simply by closing the valves 9 at both ends of the oxygen separation membrane 5, which facilitates maintenance of valve 9. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
