Description

Technical Field

[0001] This utility model relates to the field of oxygen preparation technology, and in particular to a real-time control device for the production and purity of oxygen in high-altitude environments. Background Technology

[0002] High-altitude regions have lower air pressure and thinner air, placing high demands on the stability and purity of oxygen supply. Related oxygen generation devices must meet the requirements of real-time regulation in practical applications. However, currently used high-altitude oxygen generation devices still have the following problems in use: Some oxygen generators have significant deficiencies in the filtration process. Most devices use only a single filtration method, which is difficult to remove impurities from oxygen at the same time. After long-term use, the filter media is prone to failure and is inconvenient to replace and clean, which will result in impurities remaining in the subsequent oxygen and affect the performance. In terms of gas production control, the existing device is not convenient for effective real-time monitoring and adjustment of oxygen production and delivery. When the gas production of the external oxygen generator fluctuates, it is impossible to adjust the amount of oxygen entering the storage container in time, which can easily cause problems such as excessive pressure in the storage container or insufficient oxygen supply.

[0003] To address the aforementioned issues, this utility model proposes a real-time control device for oxygen production and purity at high altitudes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing oxygen production equipment, such as the single filtration method, easy failure and inconvenience of filter media, resulting in impurities in oxygen; and the inconvenience of real-time monitoring and adjustment of gas production, which can easily lead to abnormal pressure in storage containers or insufficient oxygen supply. Therefore, this invention proposes a real-time control device for the gas production and purity of oxygen production in high-altitude areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A real-time control device for oxygen production and purity at high altitudes, comprising: A base, on the top of which a gas storage tank is fixedly installed, and on the top of which a gas outlet is fixedly provided; A gas transmission pipe is fixedly inserted through the outer wall of the gas storage tank, and a gas flow meter is installed on the gas transmission pipe; An oxygen concentration detector, which is fixedly installed on the top of the gas storage tank; A filter assembly is disposed on one side of the gas storage tank. The filter assembly includes a water storage tank and a fixing box. The fixing box is fixedly installed on one side of the water storage tank, and the other end of the gas delivery pipe is fixedly connected to one side of the fixing box. The controller is fixedly installed on the top of the base and is electrically connected to the gas flow meter and the oxygen concentration detector. Oxygen enters from the bottom of the water storage tank, undergoes preliminary filtration by the water in the tank, and then enters the fixed box through the connecting pipe for drying and adsorption. It is then transported to the gas storage tank through the gas delivery pipe. The gas flow meter detects the oxygen flow rate in real time, the oxygen concentration detector detects the oxygen purity in real time, and the controller adjusts the oxygen production and purity based on the detection signals.

[0006] A further preferred embodiment includes a water inlet pipe located at the top of the water storage tank, with a sealing cap threaded onto the top of the water inlet pipe; and a drain pipe fixedly passing through the bottom of the water storage tank, with a valve installed on the drain pipe.

[0007] A further preferred embodiment includes a connecting pipe that is fixedly inserted through one side of the water storage tank, the connecting pipe being located near the top of the water storage tank, and the other end of the connecting pipe being fixedly connected to one side of the fixing box; an air inlet is fixedly inserted through the outer wall of the water storage tank, the air inlet being located near the bottom of the water storage tank.

[0008] A further preferred embodiment: an installation cavity is provided on one side of the fixing box, the installation cavity is connected to the interior of the water storage tank through the connecting pipe, and the installation cavity is connected to the gas supply pipe; a pull-out drawer is slidably installed on the inner wall of the installation cavity, and an activated carbon adsorption plate is tightly filled inside the pull-out drawer.

[0009] A further preferred embodiment: the top and bottom of the pull-out drawer are both fixedly installed with fixing ears, both of which are located outside the mounting cavity. Two threaded holes are opened on one side of the fixing box, which are respectively located above and below the opening of the mounting cavity. Each of the two fixing ears has a hole corresponding to the adjacent threaded hole.

[0010] A further preferred embodiment: a return pipe is fixedly connected to the outer wall of the gas supply pipe, the return pipe being located between the fixed box and the gas flow meter; a second solenoid valve is provided on the return pipe, a first solenoid valve is provided on the gas supply pipe, the first solenoid valve being located between the gas flow meter and the gas storage tank, and the controller being electrically connected to the first solenoid valve and the second solenoid valve.

[0011] A further preferred embodiment: a pressure gauge is fixedly installed on the top of the gas storage tank, and the pressure gauge is electrically connected to the controller.

[0012] A further preferred embodiment: the outer wall of the water storage tank is fixedly provided with an inlet port and an outlet port, the outlet port is located above the inlet port, and the height of the outlet port does not exceed the height of the connecting pipe, and valves are provided on both the inlet port and the outlet port.

[0013] A further preferred embodiment: a support plate is fixedly installed on the top of the base, and baffles are fixedly installed on both sides of the support plate; one end of the gas supply pipe passes through the support plate, and one side of the fixing box is tightly attached to one side of the support plate; a support frame is fixedly fitted on the outer wall of the water storage tank, and one side of the support frame is fixedly connected to the support plate through a connecting bracket.

[0014] In this application, when in use, after connecting the equipment, the oxygen generated by the external oxygen generator can be delivered to the water storage tank through the air inlet. At this time, an appropriate amount of distilled water has been injected into the water storage tank through the water inlet pipe, and the top of the water inlet pipe is sealed with a sealing cap to prevent gas leakage. As the oxygen flows upward in the water storage tank, impurities in the gas can remain in the water to complete the initial filtration. When in use, the water storage tank can also be connected to an external water supply device through the liquid inlet and liquid outlet ports respectively. After opening the valves of both, the external water source can enter the water storage tank through the liquid inlet port, while the original water in the water storage tank is discharged through the liquid outlet port, realizing the continuous flow and renewal of the water source in the water storage tank. This ensures that the water in the water storage tank remains clean and that the filtration effect on impurities in the oxygen is stable. The oxygen, after initial filtration, continues to flow upwards and enters the mounting cavity of the fixed box through the connecting pipe. The pull-out drawer inside the mounting cavity is tightly filled with activated carbon adsorption plates. When oxygen passes through the activated carbon adsorption plates, the plates adsorb moisture in the oxygen and further remove trace impurities, completing the drying and deep purification of the oxygen. The pull-out drawer is secured in the mounting cavity by external screws through the fixing ears on the top and bottom that engage with the threaded holes on the fixed box, ensuring a tight seal between the pull-out drawer and the inner wall of the mounting cavity. This prevents unfiltered oxygen from directly entering subsequent pipelines, and the detachable design also facilitates the periodic replacement of the activated carbon adsorption plates. After drying and purification, oxygen enters the gas delivery pipe from the installation chamber. As the oxygen flows through the pipe, the gas flow meter monitors the flow rate in real time and transmits the data to the controller. Simultaneously, the first solenoid valve is open, guiding the oxygen towards the storage tank. After entering the storage tank, the oxygen concentration detector at the top of the tank monitors the purity of the oxygen in real time, while the pressure gauge monitors the gas pressure. Both data are transmitted synchronously to the controller. The controller receives the signals from the gas flow meter, oxygen concentration detector, and pressure gauge and analyzes the data. When the oxygen flow rate detected by the gas flow meter is within a preset range and the oxygen purity detected by the oxygen concentration detector meets the usage requirements, the controller keeps the first solenoid valve open, allowing oxygen to continuously enter the storage tank for collection and storage. The oxygen can then be discharged from the storage tank for use via the outlet. If the oxygen flow rate detected by the gas flow meter exceeds the preset value, i.e., the oxygen production is too high, the controller immediately sends control signals to the first and second solenoid valves. The controller appropriately reduces the opening of the first solenoid valve to decrease the amount of oxygen entering the storage tank, while simultaneously opening the second solenoid valve. At this time, the excess oxygen in the gas delivery pipe flows back to the connected equipment, such as another storage container or the inlet of an oxygen generator, through the return pipe, thereby regulating the oxygen production. When the oxygen concentration detector detects that the oxygen purity in the storage tank does not meet the preset requirements, the controller can adjust the operating parameters of the external oxygen generator until the oxygen purity meets the requirements, and then maintain normal oxygen delivery and storage. Throughout the process, the controller dynamically controls the solenoid valves based on the real-time data of each detection component, realizing real-time regulation of oxygen production and oxygen purity in the storage tank.

[0015] This utility model has the following beneficial effects: 1. This utility model can effectively solve the shortcomings of existing devices in terms of filtration, regulation and stability; by first allowing the prepared oxygen to enter the water storage tank, it is initially filtered by internal distilled water to remove most of the impurities; the inlet and outlet ports on the water storage tank can be connected to external water supply equipment, which can further realize the continuous flow and renewal of water source, avoid water quality deterioration, and ensure the long-term stability of the initial filtration effect; the oxygen after initial filtration then enters the fixed box, where it is dried and deeply purified by the internal activated carbon adsorption plate, which can further remove moisture and trace impurities, significantly improving the purity of the oxygen; 2. The pull-out drawer of this utility model facilitates the replacement of the activated carbon adsorption plate. Furthermore, the cooperation between the fixing ear and the threaded hole ensures a tight seal between the pull-out drawer and the mounting cavity, preventing unfiltered oxygen from directly entering the subsequent pipeline and ensuring the filtration effect. 3. This utility model's gas flow meter can detect the oxygen flow rate in the gas delivery pipe in real time. The pressure gauge and oxygen concentration detector monitor the pressure and oxygen purity in the gas storage tank, respectively. These detection data are synchronously transmitted to the controller, which can dynamically regulate the first and second solenoid valves. When the oxygen flow rate exceeds the preset value, the controller will appropriately reduce the opening of the first solenoid valve and open the second solenoid valve, allowing excess oxygen to flow back and be discharged through the return pipe, thus achieving real-time adjustment of the gas production. When the oxygen purity does not meet the requirements, the controller can adjust the operating parameters of the external oxygen generator until the oxygen purity meets the standard, ensuring stable oxygen quality in the gas storage tank. 4. The support structure composed of the support plate, baffle and support frame of this utility model can stably support the water storage tank, fixed box and other components, improve the overall stability of the device in the high-altitude environment, avoid the normal operation of the equipment due to environmental vibration, and can reliably meet the oxygen supply needs of the high-altitude area for a long time. 5. This utility model uses distilled water in the storage tank to initially filter impurities in oxygen, followed by deep purification by activated carbon in the fixed box. The adsorption plate is easy to replace and has good sealing performance, effectively improving the cleanliness of oxygen. At the same time, relying on the detection of flow meter and detector, and in conjunction with the controller and solenoid valve, the gas production and purity can be adjusted in real time to ensure long-term stable operation in high-altitude environments and meet the oxygen supply requirements.

[0023] In this embodiment, an installation cavity 22 is opened on one side of the fixed box 8. The installation cavity 22 is connected to the inside of the water storage tank 4 through the connecting pipe 13, and is also connected to the gas supply pipe 9. A pull-out drawer 21 is slidably installed on the inner wall of the installation cavity 22. The inside of the pull-out drawer 21 is tightly filled with an activated carbon adsorption plate 23, which is used to dry and adsorb and purify the gas passing through the installation cavity 22.

[0024] In this embodiment, the top and bottom of the pull-out drawer 21 are fixedly installed with fixing ears 24. The two fixing ears 24 are located outside the mounting cavity 22. Two threaded holes 25 are opened on one side of the fixing box 8, respectively located above and below the opening of the mounting cavity 22.

[0027] This application can be used in the field of oxygen preparation technology, or in other fields applicable to this application.

[0028] In another embodiment: Reference Figures 1-3 A real-time control device for oxygen production and purity at high altitudes, which is applied to the field of oxygen production technology. In this embodiment, the outer wall of the water storage tank 4 is also fixedly connected to an inlet port 14 and an outlet port 15. The outlet port 15 is located above the inlet port 14 and its height does not exceed the height of the connecting pipe 13. Both the inlet port 14 and the outlet port 15 are equipped with valves, which can be connected to external water supply equipment to realize the continuous flow and renewal of water in the water storage tank 4, and ensure a good continuous filtration effect for oxygen.

[0029] In this embodiment, a sealing cap is threaded onto the top of the water inlet pipe 16. After distilled water is added, the sealing cap can be used to seal the opening of the water inlet pipe 16 to prevent gas from escaping from the water storage tank 4.

[0030] In this embodiment, a controller 10 is fixedly installed on the top of the base 1. The controller 10 is located between two baffles 3 and is electrically connected to the gas flow meter 18, pressure gauge 26, oxygen concentration detector 27, first solenoid valve 17, and second solenoid valve 20. During actual operation, the gas flow meter 18 detects the oxygen flow rate delivered to the gas storage tank 2 in real time and transmits the data to the controller 10; the oxygen concentration detector 27 and pressure gauge 26 detect the oxygen content and pressure of the gas in the gas storage tank 2 and transmit the data to the controller 10; the controller 10 analyzes and processes the received data. When the oxygen production is too large, it controls the second solenoid valve 20 to open, allowing excess gas to flow back through the return pipe 19; when the oxygen purity or pressure in the gas storage tank 2 does not meet the requirements, the controller 10 can control the opening and closing of the first solenoid valve 17 according to preset parameters and complete the adjustment and control of the external oxygen generator, thereby completing the detection and control of oxygen production and oxygen purity in the gas storage tank 2.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the first solenoid valve 17, gas flow meter 18, second solenoid valve 20, pressure gauge 26 and oxygen concentration detector 27 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] The working principle and usage process of this technical solution are as follows: When in use, connect the equipment, and then the oxygen generated by the external oxygen generator can be delivered to the water storage tank 4 through the air inlet 5. At this time, an appropriate amount of distilled water has been injected into the water storage tank 4 through the water inlet pipe 16, and the top of the water inlet pipe 16 is sealed with a sealing cap to prevent gas leakage. During the upward flow of oxygen in the water storage tank 4, impurities in the gas can remain in the water to complete the initial filtration. When in use, the water storage tank 4 can also be connected to the external water supply equipment through the liquid inlet 14 and the liquid outlet 15 respectively. After opening the valves of both, the external water source can enter the water storage tank 4 through the liquid inlet 14, and at the same time, the original water in the water storage tank 4 is discharged through the liquid outlet 15, so as to realize the continuous flow and renewal of the water source in the water storage tank 4, which can keep the water in the water storage tank 4 clean and ensure the stable filtration effect of impurities in oxygen. The oxygen, after initial filtration, continues to flow upwards and enters the mounting cavity 22 of the fixed box 8 through the connecting pipe 13. The pull-out drawer 21 inside the mounting cavity 22 is tightly filled with activated carbon adsorption plates 23. When the oxygen passes through the activated carbon adsorption plates 23, the activated carbon adsorption plates 23 can adsorb the moisture in the oxygen and further remove trace impurities in the oxygen, thus completing the drying and deep purification of the oxygen. The pull-out drawer 21 is locked in the mounting cavity 22 by external screws through the fixing ears 24 at the top and bottom and the threaded holes 25 on the fixed box 8, ensuring a tight seal between the pull-out drawer 21 and the inner wall of the mounting cavity 22, preventing unfiltered oxygen from directly entering the subsequent pipeline. At the same time, the detachable design also makes it convenient to replace the activated carbon adsorption plates 23 periodically. After drying and purification, oxygen enters the gas supply pipe 9 from the installation cavity 22. As the oxygen flows through the gas supply pipe 9, the gas flow meter 18 detects the oxygen flow rate in real time and transmits the detected data to the controller 10. Simultaneously, the first solenoid valve 17 is in the open state, guiding the oxygen towards the storage tank 2. After the oxygen enters the storage tank 2 through the gas supply pipe 9, the oxygen concentration detector 27 at the top of the storage tank 2 detects the purity of the oxygen in the tank in real time, and the pressure gauge 26 detects the gas pressure in the tank in real time. The data detected by both are transmitted to the controller 10 synchronously. After receiving the signals transmitted by the gas flow meter 18, the oxygen concentration detector 27, and the pressure gauge 26, the controller 10 analyzes and processes the data. When the oxygen flow rate detected by the gas flow meter 18 is within the preset range and the oxygen purity detected by the oxygen concentration detector 27 meets the usage requirements, the controller 10 keeps the first solenoid valve 17 in the open state, and the oxygen continues to enter the storage tank 2 for collection and storage. Subsequently, the oxygen in the storage tank 2 can be discharged for use through the gas outlet 11. If the oxygen flow rate detected by the gas flow meter 18 exceeds the preset value, i.e., the oxygen production is too large, the controller 10 immediately sends control signals to the first solenoid valve 17 and the second solenoid valve 20 to appropriately reduce the opening of the first solenoid valve 17 to reduce the amount of oxygen entering the gas storage tank 2, and at the same time opens the second solenoid valve 20. At this time, the excess oxygen in the gas delivery pipe 9 flows back to the connected equipment, such as another storage container or the air inlet of the oxygen generator, through the return pipe 19, thereby realizing the regulation of oxygen production. When the oxygen concentration detector 27 detects that the oxygen purity in the gas storage tank 2 does not meet the preset requirements, the controller 10 can adjust the operating parameters of the external oxygen generator until the oxygen purity meets the requirements, and then maintain the normal oxygen delivery and storage state. Throughout the process, the controller 10 always dynamically controls the solenoid valves based on the real-time data of each detection component to realize the real-time regulation of oxygen production and oxygen purity in the gas storage tank 2.

[0033] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
