[0002] The pressure output by general oxygen generator is low, and can be used in places with low pressure requirements, but in the combustion industry, oxygen is used as a combustion-supporting material, and high pressure represents large gas flow, for example, in the gold industry, it takes several seconds to several minutes to melt hundreds of grams of gold, and the instantaneous gas consumption is greater than the gas output of the oxygen generator.

[0003] Some high-pressure oxygen generators on the market also have gas storage tanks, but they do not monitor the flow at the front end, and do not filter the gas, so they cannot monitor stable operation during operation, the pressure in the rear gas storage tank cannot be adjusted according to user needs and safety protection design, and the pressure of the oxygen used later cannot be adjusted according to user needs at any time, so the convenience is not enough.

Detailed Implementation

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figures 1-7 As shown, this utility model provides a technical solution: a high-pressure oxygen generator with an automatic start-stop system and a gas storage tank, including an oxygen generator 1. The oxygen generator 1 can produce oxygen with an oxygen concentration of 93±3%. The output end of the oxygen generator 1 is connected to the input end of a flow meter 2. The flow meter 2 adjusts the oxygen flow rate at the outlet of the oxygen generator. The output end of the flow meter 2 is connected to the input end of an oil-free air compressor 4 through a filter 3. The filter 3 filters out dust to prevent it from entering the oil-free air compressor 4 connected later.

[0028] The output of the oil-free air compressor 4 is connected to the input of the first one-way valve 6 and the solenoid valve 7 via a three-way valve 5. The output of the solenoid valve 7 is connected to the air tank 11. The solenoid valve 7 is connected via the three-way valve 5. When the equipment is to be started, the solenoid valve 7 is energized for 1-5 seconds before the oxygen generator and the oil-free air compressor 4 can start. The first one-way valve 6 allows oxygen to flow in only one direction and prevents backflow. The oxygen generator 1 and the air tank 11 are installed inside the body 16, which facilitates the overall installation and subsequent maintenance.

[0029] The top of the gas storage tank 11 is connected to a pressure controller 8, a pointer pressure gauge 9, a safety valve 10, and a pressure reducing valve 12. The gas storage tank 11 stores oxygen and acts as a regulating container. It has a ball valve 14 at the bottom to release the gas inside, a safety valve 10 on top to prevent overpressure and to release excess gas when the pressure exceeds a certain level, and a pointer pressure gauge 9 on top to visually indicate the gas pressure inside the gas storage tank 11 when there is no power.

[0030] The pressure controller 8 has a real-time pressure display and can set low and high pressure values, or it can only have a pressure measurement function and transmit the measured pressure to the microcontroller 15 for unified calculation and control.

[0031] The pressure reducing valve 12 is used for reducing the pressure of the gas with high pressure in the previous stage to low pressure; the pointer pressure gauge 9 can read the pressure of the gas in the gas storage tank 11 when the whole device is not powered, and can compare the pressure value on the pressure controller 8 to judge abnormal conditions, which is a redundant design.

[0032] The two oxygen generators 1 are arranged side by side, and the top of the pressure reducing valve 12 is provided with the second check valve 13 for preventing gas backflow.

[0033] In order to facilitate automatic control, the oxygen generator 1, the oil-free air compressor 4, the first check valve 6, the pressure controller 8 and the microcontroller 15 are signal connected.

[0034] The working principle and use process of the utility model are as follows: when the whole machine is powered on and in the starting state, the pressure controller 8 detects the pressure and compares it with the low pressure value; when the pressure is lower than the low pressure value, the electromagnetic valve 7 is opened for several seconds and then closed; then the oxygen generator 1 and the oil-free air compressor 4 are started simultaneously; when the pressure in the gas storage tank 11 reaches the high pressure value, the oxygen generator 1 and the oil-free air compressor 4 are stopped; the outlet of the pressure reducing valve 12 continuously outputs gas with a certain pressure; when the pressure in the gas storage tank 11 is lower than the low pressure value, the above-mentioned operation is repeated.

[0035] The oxygen generator has the characteristics that the start and stop of the machine are automatically controlled, the pressure in the gas storage tank 11 is constant, and the pressure of the oxygen output from the rear end of the pressure reducing valve 12 is stable; the low pressure is between 0.1-0.4MPa, the high pressure is between 0.4-0.6MPa, the low pressure and the high pressure are not clearly defined, the range of the pressure controller 8 is 1MPa, and the pressure at the rear end of the pressure reducing valve 12 is generally controlled between 0.2-0.4MPa, which is determined according to the pressure used in the gold and silver processing industry, combustion supporting industry, cutting industry and glass burning (glass burning) industry;

[0036] In the aquaculture industry, the pressure is usually set between 0.15-0.25MPa, the device has strong convenience and stability, the system has a flow meter 2 to detect the change of flow, a filter 3 to remove dust, and a safety valve 10 to prevent exceeding the set pressure limit, so that the simple and effective system brings great economic value to the society;

[0037] Some high-pressure oxygen generators on the market do not have a gas storage tank 11, and the oxygen generator needs to work all the time, so the gas cannot be stored, which is not good for the machine and does not have rest time, and the machine is easy to be in high temperature state for a long time, the equipment is severely worn, the vulnerable parts inside are easy to break, and in addition, there is no stored oxygen, so there is no oxygen to use when the machine is stopped for a short time, and there is no guarantee.

[0038] We oxygen machine behind a flowmeter 2, can see the value of flow, can do flow adjustment.

[0039] Flowmeter 2 behind the front of the oil-free air pump has a filter 3, which can ensure that the oxygen in the air pump is filtered to prevent dust from entering the air pump and damaging the air pump.

[0040] The gas storage tank 11 has an adjustable pressure controller 8 on the top, which can adjust the upper limit of the pressure when the machine stops and the lower limit of the pressure when the machine starts, and is automatically controlled.

[0041] The gas storage tank 11 also has a pointer pressure gauge 9 on the top, which can read the pressure in the gas storage tank 11, as a contrast to the reading of the pressure controller 8.

[0042] The gas storage tank 11 has a safety valve 10 on the top, which can ensure that the pressure of the gas storage tank 11 will not be overpressure, and the excess gas pressure can be discharged.

[0043] The gas storage tank 11 has a pressure reducing valve 12 on the top, which can adjust the pressure of the oxygen used behind, and output constant pressure.

[0044] The bottom of the gas storage tank 11 has an emptying valve, which can quickly empty the gas in the gas storage tank 11.

[0045] The outlet has a one-way valve, which can effectively prevent the backflow of oxygen.

[0046] Finally, it should be noted that the above is only a preferred example of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. within the spirit and principles of the present application shall be included within the scope of protection of the present application.
