Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production, in particular to an automatic start-stop integrated oxygen production machine. Background Art

[0002] An oxygen concentrator is a machine that produces oxygen. It utilizes air separation technology. First, air is compressed to a high density using an air compressor. The different condensation points of the air components are then used to separate the gas and liquid at a specific temperature. High-purity oxygen is then produced using oxygen concentrators and stored in gas tanks.

[0003] Traditional oxygen concentrators need to be manually started before they can begin producing oxygen. When the user uses up the oxygen in the gas tank and the subsequent oxygen production is not continued, accidents are prone to occur, resulting in problems with the equipment or people using the oxygen, which in turn leads to economic losses. Based on this, this solution provides an oxygen concentrator with automatic start and stop to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, an oxygen generator with automatic start and stop function is provided. This technical solution solves the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by this utility model is:

[0006] The oxygen-generating automatic start-stop integrated machine includes a frame, an inner wall of which is fixedly connected to an upper partition and a lower partition, and the frame is divided into a first placement area, a second placement area, and a third placement area by the upper partition and the lower partition. An air compressor and a condenser are installed in the first placement area, a gas buffer cylinder, a water vapor filter, and a recovery water tank are provided in the second placement area, and a first oxygen production tank, a second oxygen production tank, an oxygen buffer cylinder, a booster pump, and a gas storage tank are provided in the third placement area.

[0007] Preferably, the input end of the air compressor is fixedly connected to a filter box through an air pipe, and several groups of filter screens are fixedly installed inside the filter box. The output end of the air compressor is fixedly connected to a condenser through an air pipe, and the top of the condenser is connected to the inlet of the gas buffer cylinder through the air pipe.

[0008] Preferably, the top outlet of the gas buffer cylinder is fixedly connected to the input end of the water vapor filter through an air pipe, and the lower end of the gas buffer cylinder is connected to the water vapor filter through a water outlet pipe. The water vapor filter is provided with three groups, and the three groups of water vapor filters are connected in series. The lower ends of the three groups of water vapor filters are connected to the water vapor filter through the water outlet pipe. The water vapor filter is fixedly installed on the top of the lower partition.

[0009] Preferably, the output end of the water vapor filter is connected to the first oxygen production tank and the second oxygen production tank respectively through a water pipe, and an electromagnetic valve is provided between the water vapor filter and the first oxygen production tank and the second oxygen production tank. The output end of the first oxygen production tank and the output end of the second oxygen production tank are both connected to the input end of the oxygen buffer cylinder, the output end of the oxygen buffer cylinder is connected to the input end of the booster pump, and the output end of the booster pump is connected to the input end of the gas storage tank.

[0010] Preferably, the water pipe connecting the oxygen buffer cylinder and the booster pump is provided with a first pressure reducing valve, a flow meter and a dust filter in sequence, and the water pipe connecting the booster pump and the gas storage tank is installed with a first one-way valve.

[0011] Preferably, a visual pressure gauge, an electronic pressure gauge and a pressure relief valve are installed on the surface of the gas storage tank, an outlet pipe is provided at the output end of the gas storage tank, the other end of the outlet pipe is connected to external equipment, and a second pressure reducing valve and a second one-way valve are provided on the surface of the outlet pipe.

[0012] Compared with the existing technology, the utility model proposes an oxygen generator with automatic start and stop, which has the following beneficial effects:

[0013] 1. In the present invention, air first passes through a filter box, which is equipped with a filter screen inside for filtering the air. The air is then compressed by an air compressor and sent to the condenser. After cooling by the condenser, the gas reaches the gas buffer cylinder. After buffering and precipitation in the gas buffer cylinder, part of the water vapor is liquefied, and the liquefied water flows out of the water pipe and is discharged into the recovery water tank. The gas after preliminary dehydration enters the water vapor filter for secondary filtration, and the water vapor filter automatically filters and discharges the remaining water. The gas after sufficient dehydration enters the first oxygen production barrel and the second oxygen production barrel through the solenoid valve: wherein the solenoid valve works reciprocatingly, when the first oxygen production barrel starts to operate, the second oxygen production barrel blows back the whistle; and when the second oxygen production barrel starts to operate, the first oxygen production barrel blows back the whistle, thereby ensuring that the oxygen production molecules screen out dry gas. Oxygen from the oxygen generator passes through the oxygen buffer cylinder, then through a pressure reducing valve, flow meter, and dust filter, before being pressurized by a booster pump and transferred to the gas storage tank. (Because the booster pump starts without pressure, the gas is evacuated via a high-pressure solenoid valve when the equipment starts. This action is controlled by the circuit control board, and the action time can be set. The pressurized gas flows through a one-way valve to the gas storage tank.) The gas storage tank is equipped with: an electronic pressure gauge, a visual pressure gauge, an outlet pipe, and a second pressure reducing valve. The upper and lower pressure limits are 0-5 kg (adjustable as needed). If the electronic pressure gauge is connected below the lower limit, the equipment starts, and if it exceeds the upper limit, the equipment stops. This achieves startup through the pressure control device, achieving automatic start and stop, and achieving energy-saving effects. The outlet gas is reduced in pressure by the pressure reducing valve and supplied to the required equipment through a one-way valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] Reference Figure 1 As shown, the oxygen-generating automatic start-stop integrated machine includes a frame 1, an upper partition 2 and a lower partition 3 are fixedly connected to the inner wall of the frame 1, and the frame 1 is divided into a first placement area 101, a second placement area 102 and a third placement area 103 by the upper partition 2 and the lower partition 3. An air compressor 4 and a condenser 6 are installed in the first placement area 101, a gas buffer cylinder 7, a water vapor filter 8 and a recovery water tank 9 are provided in the second placement area 102, and a first oxygen production barrel 10, a second oxygen production barrel 11, an oxygen buffer cylinder 12, a booster pump 13 and a gas storage tank 14 are provided in the third placement area 103.

[0020] Specifically, in this embodiment, the input end of the air compressor 4 is fixedly connected to a filter box 5 via an air pipe. Several sets of filters are fixedly installed inside the filter box 5. The output end of the air compressor 4 is fixedly connected to a condenser 6 via an air pipe. The top end of the condenser 6 is connected to the inlet of the gas buffer cylinder 7 via an air pipe. First, the air passes through the filter box 5, which is equipped with a filter for filtering the air. The air is then compressed by the air compressor 4 and sent to the condenser 6. After cooling by the condenser 6, the gas reaches the gas buffer cylinder 7. After being buffered and precipitated by the gas buffer cylinder 7, some of the water vapor is liquefied. The liquefied water flows out of the water pipe and is discharged into the recovery water tank 9.

[0021] Specifically, in this embodiment, the top outlet of the gas buffer cylinder 7 is fixedly connected to the input end of the water vapor filter 8 through an air pipe, and the lower end of the gas buffer cylinder 7 is connected to the water vapor filter 8 through a water outlet pipe. There are three groups of water vapor filters 8, and the three groups of water vapor filters 8 are connected in series. The lower ends of the three groups of water vapor filters 8 are all connected to the water vapor filter 8 through the water outlet pipe. The water vapor filter 8 is fixedly installed on the top of the lower partition 3. After buffering and precipitation in the gas buffer cylinder 7, part of the water vapor is liquefied, and the liquefied water flows out of the water pipe and is discharged into the recovery water tank 9. The gas after preliminary dehydration enters the water vapor filter 8 for secondary filtration, and the water vapor filter 8 automatically filters and discharges the remaining water. The gas after sufficient dehydration passes through the solenoid valve 15 and enters the first oxygen production tank 10 and the second oxygen production tank 11. The working principle of the oxygen production barrel: the oxygen production barrel generally adopts the molecular sieve principle. The molecular sieve has a strong adsorption effect. After the raw air is pressurized by the compressor, it passes through the air pretreatment device to remove solid impurities such as oil, dust and water, and is cooled to room temperature. The treated compressed air enters the adsorption tower equipped with molecular sieve through the intake valve. Nitrogen, carbon dioxide and other gases in the air are adsorbed, and the outflowing gas is high-purity oxygen. When the adsorption tower reaches a certain saturation, the intake valve is closed, the flushing valve is opened, and the adsorption tower enters the flushing stage. Then the flushing valve is closed, and the desorption valve is opened to enter the desorption regeneration stage, thus completing a cycle.

[0022] Specifically, in this embodiment, the output end of the water vapor filter 8 is connected to the first oxygen production tank 10 and the second oxygen production tank 11 via a water pipe, and a solenoid valve 15 is provided between the water vapor filter 8 and the first and second oxygen production tanks 10 and 11. The output ends of the first and second oxygen production tanks 10 and 11 are both connected to the input end of the oxygen buffer cylinder 12, the output end of the oxygen buffer cylinder 12 is connected to the input end of the booster pump 13, and the output end of the booster pump 13 is connected to the input end of the gas storage tank 14. The solenoid valve 15 operates reciprocatingly. When the first oxygen production tank 10 starts operating, the second oxygen production tank 11 blows back the whistle; when the second oxygen production tank 11 starts operating, the first oxygen production tank 10 blows back the whistle, thereby ensuring that the oxygen molecules sieve out dry gas.

[0023] Specifically, in this embodiment, the water pipe connecting the oxygen buffer cylinder 12 and the booster pump 13 is sequentially equipped with a first pressure-reducing valve 16, a flowmeter 17, and a dust filter 18. The water pipe connecting the booster pump 13 and the gas storage tank 14 is also equipped with a first check valve 19. Oxygen generated by the oxygen generator passes through the oxygen buffer cylinder 12, then through the first pressure-reducing valve 16, the flowmeter 17, and the dust filter 18, before being pressurized by the booster pump 13 and transferred to the gas storage tank 14. (Because the booster pump 13 is pressureless, a high-pressure solenoid valve evacuates the gas upon startup. This action is controlled by the circuit control board, and the activation time can be set. The pressurized gas then flows through the check valve to the gas storage tank 14.)

[0024] Specifically, in this embodiment, a visual pressure gauge 20, an electronic pressure gauge 21, and a pressure relief valve 24 are installed on the surface of the gas storage tank 14. An outlet pipe 1401 is provided at the output end of the gas storage tank 14. The other end of the outlet pipe 1401 is connected to external equipment, and a second pressure reducing valve 22 and a second one-way valve 23 are provided on the surface of the outlet pipe 1401. The gas storage tank 14 is installed with: an electronic pressure gauge 21, a visual pressure gauge 20, an outlet pipe 1401, a second pressure reducing valve 22, and a pressure relief valve 24. The upper and lower pressure limits are 0-5 kg (adjustable as needed). When the electronic pressure gauge 21 is connected, the equipment starts when the pressure is below the lower limit, and stops when the pressure is above the upper limit. This enables the start-up of the pressure control device and the realization of self-start and stop to achieve energy saving. The outlet gas is reduced in pressure by the second pressure reducing valve 22 and supplied to the required equipment through the second one-way valve 23.

[0025] The working principle of the utility model is as follows: first, air passes through the filter box 5, which is equipped with a filter screen for filtering the air. Then, the air is compressed by the air compressor 4 and sent to the condenser 6. After cooling by the condenser 6, the gas reaches the gas buffer cylinder 7. After being buffered and precipitated by the gas buffer cylinder 7, part of the water vapor is liquefied. The liquefied water flows out of the water pipe and is discharged into the recovery water tank 9. After being buffered and precipitated by the gas buffer cylinder 7, part of the water vapor is liquefied. The liquefied water flows out of the water pipe and is discharged into the recovery water tank 9. After the initial water removal, the gas enters the water vapor filter 8 for secondary filtration. The water vapor filter 8 then automatically filters and discharges the remaining water. The gas after sufficient dehydration passes through the solenoid valve 15 and enters the first oxygen production tank 10 and the second oxygen production tank 11; the solenoid valve 15 works reciprocatingly, when the first oxygen production tank 10 starts running, the second oxygen production tank 11 blows back the whistle; and when the second oxygen production tank 11 starts running, the first oxygen production tank 10 blows back the whistle, thereby ensuring that the oxygen molecules sieve out dry gas; the oxygen in the oxygen production tanks passes through the oxygen buffer cylinder 12, and then passes through the first pressure reducing valve 16 - flow meter 17 - dust filter 18, and is pressurized by the booster pump 13 to the gas storage tank 14.

[0026] The gas tank 14 is equipped with an electronic pressure gauge 21, a visual pressure gauge 20, an outlet pipe 1401, and a second pressure reducing valve 22. The overall upper and lower pressure limits of the gas tank 14 are between 0 and 5 kg (adjustable as needed). When the electronic pressure gauge 21 is on, the device starts when the pressure falls below the lower limit, and stops when the pressure rises above the upper limit. This allows for automatic start-stop and energy savings through the pressure control device. The outlet gas is reduced in pressure by the second pressure reducing valve 22 and supplied to the required equipment through the second check valve 23.
