Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Figure 1 This is a schematic diagram of the structure of an automatic oxygen distribution and filling device provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the device includes:

[0020] Compressed air source unit, used to compress air;

[0021] Specifically, the compressed air source unit includes:

[0022] Compressor 1 is used to compress air; it compresses air to a higher pressure, providing a continuous supply of high-pressure gas. Compressor 1 is the air source provider for the entire system, ensuring that subsequent processing can proceed smoothly.

[0023] Air buffer tank 2, the input end of which is connected to the output end of compressor 1, is used to store compressed air.

[0024] The function of air buffer tank 2 is to store compressed air from compressor 1 to reduce pressure fluctuations caused by compressor 1 starting and stopping, thus providing a stable air supply. The buffer tank enables the system to maintain a stable output pressure during peak gas demand periods.

[0025] Furthermore, the air buffer tank 2 is connected to the pressure transmitter 3, which monitors the air pressure inside the air buffer tank 2 in real time and transmits the pressure data to the control unit. Based on the information fed back by the pressure transmitter 3, the control unit can determine whether the gas system is within the normal operating pressure range, ensuring stable system operation.

[0026] Furthermore, the air buffer tank 2 is connected to the safety valve 4. The safety valve 4 is mainly used to automatically open and release excess gas when the air pressure exceeds the set safety threshold, preventing damage to the air buffer tank 2 or the system due to excessive pressure. The safety valve 4 ensures that the air pressure does not exceed the design safety range of the equipment, preventing safety hazards caused by excessive pressure.

[0027] A gas pretreatment unit, the input end of which is connected to the output end of the compressed air source unit, is used to pretreat the compressed air;

[0028] Specifically, the gas pretreatment unit includes a filtration module and a drying module 10;

[0029] The input end of the filter module is connected to the output end of the air buffer tank 2;

[0030] The output end of the filter module is connected to the first input end of the drying module 10.

[0031] Specifically, the filtering module includes: a four-stage filter group;

[0032] The four-stage filter group includes: CS-level filter 6, U-level filter 7, S-level filter 8, and H-level filter 9.

[0033] CS-grade filter 6: Used for coarse filtration to remove larger particles in the air, such as dust.

[0034] U-class filter 7: Used to remove medium-sized particulate matter, ensuring the removal of impurities from the air;

[0035] S-Class Filter 8: Used for precision filtration to remove smaller particles and ensure higher gas purity;

[0036] H-Class Filter 9: Used for high-precision filtration, further removing impurities such as fine particles and oil mist to ensure that air quality meets the highest standards.

[0037] The drying module 10 is used to remove moisture from the air, preventing moisture from affecting subsequent oxygen separation, storage, and transportation. The drying module 10 ensures the dryness of the gas within the system, avoiding equipment damage or reduced separation efficiency due to excessive moisture.

[0038] An oxygen-nitrogen separation unit, comprising: an oxygen-nitrogen separation module 11, a first oxygen-enriched storage tank 15, and a second oxygen-enriched storage tank 16;

[0039] The first output of the gas pretreatment unit is connected to the input of the first oxygen-enriched storage tank 15 via a first regulating valve 12; the first output of the oxygen-nitrogen separation module 11 is connected to the input of the first oxygen-enriched storage tank 15 via a second regulating valve 13; the second output of the oxygen-nitrogen separation module 11 is connected to the input of the gas separator 22 via a third regulating valve 14; the output of the first oxygen-enriched storage tank 15 is connected to the input of the second oxygen-enriched storage tank 16.

[0040] Furthermore, the second input end of the drying module 10 is connected to the first output end of the gas distributor 22 via a manual valve 5 for recirculating nitrogen.

[0041] The first output end of the drying module 10 is connected to the input end of the first oxygen-enriched storage tank 15 through the first regulating valve 12.

[0042] The second output terminal of the drying module 10 is connected to the input terminal of the oxygen-nitrogen separation module 11.

[0043] Specifically, the oxygen-nitrogen separation module 11 separates nitrogen and oxygen in the air. The separated oxygen-enriched gas is stored in the first oxygen-enriched storage tank 15, and the separated nitrogen is transported to the gas distributor 22.

[0044] The first output end of the gas distributor 22 is connected to the second input end of the drying module 10, which enables the function of nitrogen reabsorption, that is, nitrogen is recovered from the gas distributor 22 to provide reuse of the gas inside the drying module 10 and reduce energy waste.

[0045] The second output end of the gas distributor 22 is connected to the emission silencer 23 for outputting nitrogen gas; specifically, it is used to discharge nitrogen gas through the silencer, which reduces noise during the emission process and avoids environmental interference when the gas is emitted.

[0046] The third output end of the gas separator 22 is a sampling port 24, which is used to extract nitrogen gas from the gas separator 22.

[0047] The automatic oxygen distribution and filling device further includes:

[0048] A concentration detection unit is used to detect the concentration of nitrogen gas taken out from the sampling port 24;

[0049] The control unit is electrically connected to the first regulating valve 12, the second regulating valve 13, and the third regulating valve 14, and is used to automatically control the opening degree of the first regulating valve 12, the second regulating valve 13, and the third regulating valve 14 according to the oxygen purity.

[0050] Furthermore, the control unit is electrically connected to the concentration detection unit and is used to control the opening degree of the first regulating valve 12, the second regulating valve 13, and the third regulating valve 14 according to the nitrogen concentration measured by the concentration detection unit, so as to adjust the oxygen concentration to the target range.

[0051] In the air, the concentrations of oxygen and nitrogen are usually opposite. If we know the concentration of nitrogen, we can deduce the concentration of oxygen by working backward. Based on the concentration of nitrogen measured by the concentration detection unit, the concentration of oxygen can be determined. Then, the control unit controls the opening of the first regulating valve 12, the second regulating valve 13, and the third regulating valve 14 to adjust the oxygen concentration to the target range.

[0052] The purity of the oxygen being filled can be precisely and stably adjusted from 30% to 40% according to the settings, with an adjustment accuracy of ±1%, that is, arbitrarily adjustable from 30%, 31%, 32% to 40%. The control unit adjusts the opening of the first regulating valve 12, the second regulating valve 13, and the third regulating valve 14 to ensure that the oxygen concentration is precisely adjusted within the range of 30% to 40%.

[0053] The first oxygen-enriched storage tank 15 is connected to the analyzer 17. The main function of the analyzer 17 is to monitor the oxygen concentration in the first oxygen-enriched storage tank 15 in real time to ensure that it meets the predetermined standards. The analyzer 17 can accurately measure the purity of oxygen and feed the detection results back to the control unit, enabling the control unit to automatically adjust based on the current oxygen concentration.

[0054] Because the oxygen concentration in the first oxygen-enriched storage tank 15 is affected by the regulating valve in real time, the gas concentration is unstable. Therefore, in order to overcome the problem of unstable oxygen concentration in the first oxygen-enriched storage tank 15, a second oxygen-enriched storage tank 16 is set up. The second oxygen-enriched storage tank 16 can buffer this fluctuation and ensure stable gas supply quality.

[0055] Furthermore, a manual valve 5, a flow meter 18, a manual valve 5, and a sterilization filter 19 are sequentially provided between the output end of the first oxygen-enriched storage tank 15 and the input end of the second oxygen-enriched storage tank 16.

[0056] Manual valve 5, flow meter 18, and sterilizing filter 19: These components are sequentially installed between the output end of the first oxygen-enriched storage tank 15 and the input end of the second oxygen-enriched storage tank 16. They are used to control the gas flow rate, monitor the airflow, and ensure the purity of the gas flowing into the second oxygen-enriched storage tank 16. Manual valve 5 is used for manual adjustment of the airflow, flow meter 18 is used for precise flow measurement, and sterilizing filter 19 is used to remove bacteria from the air, ensuring that the oxygen in the system is pure and uncontaminated.

[0057] In an optional embodiment, the bottom ends of the air buffer tank 2, the first oxygen-enriched storage tank 15, and the second oxygen-enriched storage tank 16 are provided with drain ports for periodically removing sediments and impurities from the storage tanks to maintain the cleanliness and stable operation of the gas storage system.

[0058] An oxygen booster unit, the input end of which is connected to the output end of the second oxygen-enriched storage tank 16;

[0059] The stored oxygen-enriched gas is pressurized to increase the gas pressure and ensure that the oxygen can be delivered to downstream equipment at an appropriate pressure. Specifically, the oxygen pressurization unit is an oxygen-enriched pressurizer 20, which can pressurize the gas to 30MPa.

[0060] The output unit has its input end connected to the output end of the oxygen boosting unit, and the output end is used to deliver the boosted oxygen to various gas devices 21.

[0061] The various gas devices 21 include, but are not limited to, boat-mounted breathing gas cylinders, self-contained breathing apparatus, escape breathing apparatus, conventional diving gas cylinders, medical cabins, etc.

[0062] The beneficial effects of this utility model are:

[0063] Stable Oxygen Concentration: By setting up multiple storage tanks, regulating valves, and concentration detection units, this invention can precisely adjust and stably control the oxygen concentration, ensuring that the oxygen concentration output by the system is always maintained within the set range. Improved System Reliability: The setting of the second oxygen-enriched storage tank 16 effectively alleviates the oxygen concentration fluctuation problem in the first oxygen-enriched storage tank 15, improving the stability of the gas supply. Precise Airflow Control: Through the configuration of flow meter 18 and manual valve 5, the system can precisely adjust the gas flow rate, ensuring that the gas supply at each stage meets the requirements. Ensured Gas Quality: The sterilization filter 19 effectively removes impurities from the gas, ensuring the purity of the output gas and meeting high-standard application requirements. Enhanced Operational Flexibility: The design of manual valve 5 provides operational flexibility, facilitating system adjustment, maintenance, and troubleshooting, ensuring efficient system operation. Intelligent Control: The cooperation between the concentration detection unit and the control unit enables automatic adjustment of the oxygen concentration, reducing manual intervention and improving the level of automation.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this 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 of the technical features.
