Description

Technical Field

[0001] This invention relates to the field of oxygen generator technology, and more specifically, to a high-end air separation oxygen generator using molecular sieves. Background Technology

[0002] In fields such as medical treatment, industrial production, and oxygen supply in high-altitude environments, a high-purity, stable, and continuous oxygen supply is a core requirement for ensuring production safety and operational efficiency. Among the current mainstream oxygen preparation equipment, molecular sieve air separation oxygen generators, with their advantages of on-site oxygen production and no need for storage and transportation, are gradually replacing traditional methods such as cylinder oxygen and liquid oxygen, becoming the mainstream choice.

[0003] Most devices only use a single filter for dust removal, which cannot effectively remove oil mist, odors and moisture from the air. Oil mist will adhere to the surface of the molecular sieve and block the micropores, moisture will cause the molecular sieve to lose hydration, and odor gases may even react chemically with the molecular sieve, causing its adsorption capacity to decrease permanently. After long-term operation, it will reduce the purity of the oxygen produced, which cannot meet the needs of medical intensive care, precision industry and other scenarios. Summary of the Invention

[0010] Preferably, the replacement component includes a second rectangular connecting block, with molecular sieves connected to both sides of the upper end of the second rectangular connecting block, and first rectangular sliding blocks connected to the outer sides of both ends of the second rectangular connecting block. A first threaded rod passes through the middle part of each first rectangular sliding block, and a first drive motor is connected to the lower end of each first threaded rod.

[0011] Preferably, the moving component includes a first rotating belt, with first rotating wheels meshing in the inner cavities at both ends of the first rotating belt.

[0015] Compared with the prior art, the advantages of this invention are: 1) In this invention, a three-stage pretreatment structure consisting of a first circular filter plate, a heating wire, and an activated carbon filter block is used to achieve stratified air purification. The first circular filter plate first traps large dust particles to prevent subsequent components from clogging. The heating wire can quickly heat the air to remove moisture and prevent the molecular sieve from failing due to hydration reaction. The activated carbon filter block adsorbs oil mist and odor gases through its porous surface structure, preventing oil stains from clogging the micropores of the molecular sieve and chemical gases from damaging the adsorption sites. This structure can improve the air impurity removal rate, meet the stringent purity requirements of high-end scenarios such as intensive care and semiconductor manufacturing, and extend the service life of the oxygen concentrator.

[0016] 2) In this invention, the circular trigger block of the fan assembly and the trigger groove of the first filter mechanism are linked together. With the signal transmission of the infrared sensor and the heating module, the heating wire is only triggered when the fan starts and air enters. This avoids the energy waste of the dehumidification module in existing equipment running continuously. At the same time, the start-up of the heating wire is synchronized with the operation of the fan. The heating power can be dynamically adjusted according to the air flow. Compared with the traditional constant heat dehumidification design, energy consumption can be reduced, and the dehumidification effect and energy saving requirements can be taken into account.

[0017] 3) In this invention, the replacement component is driven by the first drive motor to rotate the first threaded rod, which can drive the second rectangular connecting block and the molecular sieve to rise automatically along the vertical slide. At the same time, the moving component is driven by the linkage of the first rotating belt, the bevel gear and the second threaded rod to move the rectangular sealing block along the horizontal slide, so as to realize that the replacement port automatically opens when the molecular sieve rises and automatically seals after replacement, thereby improving the replacement efficiency of the molecular sieve.

[0020] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A high-end air separation oxygen generator with molecular sieves includes an organic body 1, a control panel 2 connected to the front surface of the body 1, and a filter assembly 3 connected to the side of the body 1. Please see Figure 4The filter assembly 3 includes a first circular filter plate 301, one end of which is connected to a fan assembly 302, and the end of the fan assembly 302 away from the first circular filter plate 301 is connected to a first filter mechanism 303.

[0021] Please see Figure 1 , Figure 2 and Figure 3 One end of the filter assembly 3 is connected to a first ventilation duct 4, and the end of the first ventilation duct 4 away from the filter assembly 3 is connected to a dust collector bag 5. A high-pressure nozzle 6 is installed above the dust collector bag 5, and one end of the high-pressure nozzle 6 is connected to an air pump 7. A second ventilation duct 8 is opened at the upper end of the dust collector bag 5.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The second ventilation duct 8 is connected to an air compressor 9 at the end away from the dust collector bag 5. The air compressor 9 is connected to a replacement component assembly 10 at the end away from the second ventilation duct 8. A replacement port 11 is provided above the replacement component assembly 10, and a conical discharge port 12 is provided below the dust collector bag 5. A storage chamber 13 is provided at the lower end of the conical discharge port 12.

[0023] Specifically, the gas flow sensor in the second ventilation duct 8 can monitor the air flow behind the dust collector bag 5 in real time. When the flow rate is lower than the set threshold, the dust removal module immediately transmits the signal to the oxygen generation unit. The second control module starts the air pump 7 and uses the high-pressure nozzle 6 to spray high-pressure gas onto the dust collector bag 5, causing the bag to shake and discharging the dust into the storage chamber 13 through the conical discharge port 12. The whole process does not require manual intervention, avoiding the risk of downtime caused by the lag in manual inspection of existing equipment, and ensuring that the oxygen generation process is continuous and uninterrupted. It is especially suitable for scenarios where oxygen cannot be interrupted, such as medical emergency and continuous industrial production.

[0024] Please see Figure 5 The fan assembly 302 includes a fan 304. A fan fixing frame 305 is connected to the outside of the fan 304. A first circular rotating block 306 is connected to the end of the fan fixing frame 305 away from the fan 304. A first rectangular connecting block 307 is connected to the outer surface of the first circular rotating block 306. A circular trigger block 308 is connected to the end of the first rectangular connecting block 307 away from the first circular rotating block 306. A first connecting rod is connected to the end of the first circular rotating block 306 facing the fan fixing frame 305. The first connecting rod is connected to the shaft of the fan 304 through the fan fixing frame 305. The first connecting rod is rotatably connected to the fan fixing frame 305. When the oxygen generator stops oxygen production, the fan 304 will reverse 180 degrees, thereby separating the circular trigger block 308 from the trigger groove 312.

[0025] Please see Figure 6 The first filtration mechanism 303 includes a first annular connecting block 309. The surface of the first annular connecting block 309 facing the fan assembly 302 has an annular groove 310. A first moving rod 311 is connected to the inner cavity of the annular groove 310. A trigger groove 312 is opened at one end of the first moving rod 311 facing the fan assembly 302. An electric heating wire 313 is connected to the inner wall of the first annular connecting block 309. An activated carbon filter block 314 is connected to the end of the electric heating wire 313 away from the fan fixing frame 305. A plurality of first filter holes are opened on the surface of the activated carbon filter block 314. The activated carbon filter block 314 is connected to the first annular connecting block 309. A circular trigger block 308 fits into the trigger groove 312.

[0026] Specifically, the three-stage pretreatment structure of the first circular filter plate 301, the heating wire 313, and the activated carbon filter block 314 achieves stratified air purification. The first circular filter plate 301 first traps large dust particles to prevent clogging of subsequent components; the heating wire 313 can quickly heat the air to remove moisture and prevent the molecular sieve from failing due to hydration reaction; the activated carbon filter block 314 adsorbs oil mist and odor gases through its porous surface structure, preventing oil stains from clogging the micropores of the molecular sieve and chemical gases from damaging the adsorption sites. This structure can improve the air impurity removal rate, meet the stringent purity requirements of high-end scenarios such as intensive care and semiconductor manufacturing, and extend the service life of the oxygen concentrator.

[0027] Please see Figure 7 The replacement component 10 includes a second rectangular connecting block 101. Molecular sieves 102 are connected to the upper two sides of the second rectangular connecting block 101, and first rectangular sliding blocks 103 are connected to the outer sides of both ends of the second rectangular connecting block 101. A first threaded rod 104 passes through the middle part of each first rectangular sliding block 103. A first drive motor 105 is connected to the lower end of each first threaded rod 104. A moving component 106 is connected to the top of the first threaded rod 104 connected near the air compressor 9.

[0028] Through the linkage design of the circular trigger block 308 of the fan assembly 302 and the trigger groove 312 of the first filter mechanism 303, and in conjunction with the signal transmission of the infrared sensor and the heating module, the heating wire 313 is only triggered to work when the fan 304 is started and air enters, avoiding the energy waste of the dehumidification module of the existing equipment running continuously. At the same time, the start-up of the heating wire 313 is synchronized with the operation of the fan 304, and the heating power can be dynamically adjusted according to the air flow. Compared with the traditional constant heat dehumidification design, it can reduce energy consumption and take into account both dehumidification effect and energy saving requirements.

[0029] Please see Figure 8The moving component 106 includes a first rotating belt 107, with first rotating wheels 108 meshing in the inner cavities at both ends of the first rotating belt 107. A first bevel gear 109 is connected to the upper end of the first rotating wheel 108, which is connected away from the first threaded rod 104. A second bevel gear 110 meshes with one end of the first bevel gear 109. A second threaded rod 111 is connected to the end of the second bevel gear 110, which is away from the first bevel gear 109. A rectangular sealing block 112 is connected to the end of the second threaded rod 111, which is away from the second bevel gear 110. The lower surface of the first rotating wheel 108, which is connected to the end near the first threaded rod 104, is connected to the upper end of the first threaded rod 104. The inner cavity of the body 1 is provided with a vertical sliding groove and a horizontal sliding groove. A first rectangular sliding block 103 is installed in the inner cavity of the vertical sliding groove, and a rectangular sealing block 112 is installed in the inner cavity of the horizontal sliding groove.

[0030] Specifically, the replacement component 10 drives the first threaded rod 104 to rotate via the first drive motor 105, which in turn drives the second rectangular connecting block 101 and the molecular sieve 102 to automatically rise along the vertical slide. At the same time, the moving component 106 drives the rectangular sealing block 112 to move along the transverse slide through the linkage of the first rotating belt 107, the bevel gear, and the second threaded rod 111. This enables the replacement port 11 to automatically open when the molecular sieve 102 rises and to automatically seal after replacement, thereby improving the replacement efficiency of the molecular sieve 102.

[0031] Please see Figure 9 An infrared sensor is installed in the inner cavity of the body 1, a gas flow sensor is installed in the inner cavity of the second ventilation duct 8, an oxygen flow sensor is installed in the inner cavity of the replacement component 10, and an oxygen generation unit is installed in the control panel 2. The input end of the oxygen generation unit is connected to a heating module, a dust removal module and an oxygen detection module, and the output end of the oxygen generation unit is connected to a first control module, a second control module and a third control module.

[0032] The input terminal of the heating module is connected to the data input terminal of the infrared sensor; the output terminal of the first control module is connected to the data input terminal of the heating wire 313; the input terminal of the dust removal module is connected to the data input terminal of the gas flow sensor; the output terminal of the second control module is connected to the data output terminal of the air pump 7; the input terminal of the oxygen detection module is connected to the data input terminal of the oxygen flow sensor; and the output terminal of the third control module is connected to the data output terminal of the first drive motor 105.

[0033] Working principle: First, the fan 304 in the oxygen generator is started through the control panel 2. As the fan 304 is started, it will draw the natural air from the outside through the first circular filter plate 301 and deliver it to the inner cavity of the filter assembly 3. The rotation of the fan 304 will drive the first circular rotating block 306, the first rectangular connecting block 307 and the circular trigger block 308 to rotate. The rotation of the circular trigger block 308 will coincide with the trigger groove 312 and drive the first moving rod 311 to move along the annular groove 310. At this time, when the infrared sensor detects that the circular trigger block 308 coincides with the trigger groove 312, it will send the detected data to the oxygen processing unit through the heating module and let the oxygen processing unit start the heating wire 313 through the first control module to heat the air and remove the moisture in the air. When the dehumidified air is delivered to the first ventilation duct 4 through the activated carbon filter block 314, the activated carbon filter block 314 will adsorb the odor and oil in the air. Air delivered to the first ventilation duct 4 is transported to the second ventilation duct 8 through the dust collector bag 5, and then from the second ventilation duct 8 to the air compressor 9. During this process, the gas flow sensor monitors the air flow rate after filtration by the dust collector bag 5 in real time. If the air flow rate after filtration reaches the threshold range set by the gas flow sensor, the detection data is transmitted to the oxygen generation unit through the dust removal module, and the oxygen generation unit stops the fan 304 and starts the air pump 7 through the second control module, thereby spraying high-pressure gas into the dust collector bag 5 through the high-pressure nozzle 6, which causes the dust collector bag 5 to shake, and the impurities and dust filtered on the surface of the dust collector bag 5 are transported to the storage chamber 13 through the conical discharge port 12, and then the oxygen generation operation is restarted. When gas enters the molecular sieve 102 through the air compressor 9, it will perform oxygen production. During the oxygen production process of the molecular sieve 102, the oxygen flow sensor will monitor the oxygen flow in real time. If the oxygen flow rate reaches the threshold range set by the oxygen flow sensor, the detected data will be transmitted to the oxygen production processing unit through the oxygen detection module. The oxygen production processing unit will then transmit the detected data to the user's mobile phone through the control panel 2. The user will then start the first drive motor 105 through the third control module in the control panel 2, which will drive the first threaded rod 104 and the first rotating wheel 108 to rotate. The rotation of the first threaded rod 104 will drive the second rectangular connecting block 101, the molecular sieve 102 and the first rectangular sliding block 103 to move upward along the vertical groove. The rotation of the first rotating wheel 108 will drive the first rotating belt 107 to rotate, thereby driving the first rotating wheel 108 and the first bevel gear 109 meshing at the other end of the first rotating belt 107 to rotate, which in turn drives the second bevel gear 110 and the second threaded rod 111 to rotate. As the second threaded rod 111 rotates, it will drive the rectangular sealing block 112 to move along the transverse groove toward the first bevel gear 109. During the movement of the molecular sieve 102, when the top of the molecular sieve 102 is aligned with the top of the first threaded rod 104, the rectangular sealing block 112 will separate from the replacement port 11. If the first rectangular sliding block 103 moves to the top of the vertical slide groove, it will cause the rectangular sealing block 112 to move to the other end of the horizontal slide groove. At this time, the user can replace the molecular sieve 102, then reset the replacement assembly 10, and restart the oxygen generation operation, thus ending all operations.
