Description

Technical Field

[0001] The present invention belongs to the technical field of tank filling machines, and in particular relates to a multi-mode inflation pipeline system and a tank filling machine for an oxygen tank. Background Art

[0002] An oxygen chamber is a sealed device filled with oxygen that is slightly higher than atmospheric pressure. It is mainly used for the treatment of carbon monoxide poisoning, decompression sickness, hypoxic-ischemic encephalopathy, as well as physical recovery of athletes and relief of sub-health conditions. Since a certain pressure of oxygen is filled into the oxygen chamber, more oxygen can be dissolved into the human body, which is of great help in the treatment and relief of the above-mentioned situations. Depending on the construction material of the chamber, oxygen chambers can be divided into hard chambers and soft chambers. The former is built with fixed buildings or hard chambers, generally has a larger space and can accommodate multiple people at the same time; the latter is mainly made of retractable flexible sealing materials, generally has a smaller space and is often only for single use.

[0003] Whether it is a hard cabin or a soft cabin, the pressure and gas composition in the cabin need to be controlled and adjusted before the oxygen cabin is used, that is, the cabin is filled. For hard cabins with larger spaces, a gas supply system or a large-scale cabin filling equipment that is matched with it is often used for cabin filling. The gas supply system or large-scale cabin filling equipment generally has two important components: an air supply unit and an oxygen supply unit. The gas stored in a tank group in liquid form is mixed by a controller after gasification, and finally the supply of oxygen-rich mixed gas is realized. For soft cabins with smaller volumes, oxygen tanks or oxygen generators are often used for supply. For example, the prior art CN 202173548 U in 2012 discloses a soft oxygen cabin equipped with an oxygen generator, which publicly uses an oxygen generator to supply oxygen to the soft oxygen cabin. However, there are problems such as unstable gas supply, inconvenient operation, and difficulty in efficacy control when directly using a gas tank or an oxygen generator to supply oxygen.

[0004] In order to solve the problem of directly using medical or household oxygen generators to provide gas source, which leads to inconvenient operation and difficult to control the efficacy, the prior art CN 107374874 A in 2017 disclosed an oxygen-enriched health cabin oxygen generator used for health preservation. The oxygen generator uses an oxygen production module with an oxygen production compressor and a high-pressure gas source module with an inflation compressor, which are arranged in parallel to provide high-concentration oxygen and high-pressure gas respectively, and form a mixed gas after mixing, which is finally delivered to the oxygen-enriched health cabin. The prior art CN 118718652 A in 2024 disclosed an oxygen generator dedicated to oxygen cabin inflation with adjustable cabin pressure. The chassis of the oxygen generator is divided into four main parts, namely, an inflation air compressor module, an oxygen production air compressor module, an adsorption state module and a booster air compressor module.

[0005] Although the above prior art has achieved convenient control of the oxygen generator filling process, the following problems still exist:

[0006] The overall structure of the tank filling equipment is relatively complex, the manufacturing cost is relatively high, and the energy consumption is high. At present, the existing tank filling equipment requires at least two air compressors, which are large in size, high in cost, and high in energy consumption. When multiple air compressors are used, the overall structure of the equipment is relatively complex and occupies a large space, which will undoubtedly increase the manufacturing cost and make the assembly process more cumbersome. At the same time, because the tank filling equipment uses multiple air compressors, the piping system is complex and the integration is low, and the overall structure still needs to be further optimized. Summary of the invention

[0029] (III) Beneficial effects

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. By optimizing the pipeline system of the filling equipment, a single air compressor is creatively used to realize the multi-mode supply of pure air, high-purity oxygen and oxygen-enriched gas mixed with air and oxygen to the oxygen cabin, which can not only ensure the filling pressure, but also realize the regulation of the oxygen content of the cabin. After the air enters the pipeline from the inlet, it enters the air compressor after filtering and silencing, and a three-way is set on the outlet pipeline of the compressor to divert the gas. One path of the diverted gas is used as the first supply path of pure air, and a distribution valve is set on the gas path of the other gas, so that the gas selectively enters the oxygen production unit or the second supply path of pure air. The air passing through the distribution valve is separated into high-purity oxygen after passing through the oxygen production unit, and the high-purity oxygen flows out through the oxygen supply path. By changing the opening state of the distribution valve and the control valve on the first supply path of pure air, multiple supply modes of single-way or dual-way air supply, high-purity oxygen supply, and oxygen-enriched gas supply formed by mixing one path of air and one path of high-purity oxygen can be realized.

[0032] Second, because the pipeline system and the tank filling machine using the pipeline system only use a single compressor, the volume of the equipment can be reduced, the manufacturing cost, the energy consumption of the equipment and the complexity of the overall structure of the equipment can be reduced, which is conducive to simplifying the assembly process and improving the assembly work efficiency.

[0033] 3. The filling machine is also equipped with an ozone generator to fill the cabin with ozone for disinfection to improve the biological safety of different personnel in the oxygen cabin. At the same time, the filling machine not only integrates a bacterial filter, flow meter, and oxygen concentration sensor on the inflation pipeline, but also has multiple sensors such as oxygen concentration sensor, temperature sensor, carbon dioxide sensor, and pressure sensor connected to the oxygen cabin, so that the filling machine integrates multiple functions, thereby fully ensuring the safety of the oxygen cabin.

DETAILED DESCRIPTION

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different embodiments as defined and covered by the claims.

[0041] In the following description of the present invention, it should be noted that terms such as "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and "vertical" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore, should not be understood as limiting the present invention.

[0042] In the following description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, in the following description of the present invention, unless otherwise specified, “plurality”, “multiple groups”, and “multiple roots” mean two or more.

[0044] The materials, parts, and devices used in the following embodiments are conventional materials, parts, and devices in the art unless otherwise specified, and can be obtained by those skilled in the art through commercial channels, including but not limited to air compressors, air filters, molecular sieves, gas circuit control valves, pressure regulating valves, control valves, pressure relief valves, can-shaped silencers, electronic flow meters, temperature sensors, pressure sensors, oxygen sensors, carbon dioxide sensors, main control boards, displays, tees, joints, connecting pipes, and the like.

[0045] Figure 1 The schematic diagram of the multi-mode inflation pipeline system in a preferred embodiment of the present invention is shown schematically. Figure 1 It can be seen that in this preferred embodiment, the multi-mode inflation pipeline system includes an air filtration device consisting of a primary filtration device 1 and a fine filtration device 2, an intake silencer device I 3, an air compressor 4, a cooler 5, a distribution valve 6, an air circuit control valve 7, a pressure relief valve 8, an oxygen preparation unit, a bacterial filter 13, an electronic flow meter 14, an oxygen sensor I 15, and a main control board 21 as a control device and common connectors (not shown) such as connecting pipes, elbows, and tees that connect various components.

[0046] Among them, after the raw air enters from the air inlet of the tank filling machine, it is first filtered by the air filter device composed of the primary filter device 1 and the fine filter device 2 to remove particulate impurities. Then, the air enters the air compressor 4 through the pipeline for compression to form compressed air. Since the compressor generates heat and causes the gas temperature to rise after working for a long time, a cooler 5 is installed on the pipeline after the compressed air is discharged to cool the compressed air. The cooled compressed air flows along the main channel to the tee, and then is divided into two branches.

[0047] The first branch is provided with an air path control valve 7 to control the opening and closing of the air path and the size of the flow rate. This path is finally connected to the oxygen cabin through a joint to form a first air supply path. This path can provide sufficient air pressure for the inflation of the oxygen cabin.

[0048] The second branch is connected to the inlet of the distribution valve 6, and the distribution valve 6 is provided with at least two outlets that can only be conducted in one way. Among them, one outlet is connected to the control valve 9 of the oxygen production unit through a connecting pipe to form an oxygen supply passage. The other outlet is connected to a connecting pipe with a pressure relief valve 8 to finally form a second air supply passage. The first air supply passage and the second air supply passage can be connected to the equipment joint separately, or they can be first connected to the equipment joint after being combined through a tee to form one air supply passage, and then connected to the equipment joint.

[0049] The oxygen production unit adopts a double molecular sieve tank group, and the air inlet end is a control valve 9. Compressed air enters the molecular sieve tank 10 in two ways through the control valve 9, and oxygen and nitrogen are separated from the molecular sieve in the molecular sieve tank. Oxygen is collected into the oxygen storage tank 11 through a connecting pipe and a one-way valve, while nitrogen enters the outlet silencer II 25 through the outlet hole of the control valve 9, and is finally discharged after silence.

[0050] The oxygen in the oxygen storage tank 11 flows out from the oxygen production unit through the pressure regulating valve 12, and a bacterial filter 13 is provided in the oxygen supply pipeline through which it flows, for removing bacteria and other microorganisms in the air. In order to detect the high-concentration oxygen that flows out, an electronic flow meter 14 and an oxygen sensor 1 15 are also provided to monitor and feedback the flow rate and oxygen concentration of oxygen in the pipeline. Finally, the prepared high-concentration oxygen passes through a one-way valve and then enters the oxygen cabin through a joint to form an oxygen supply passage. Of course, it can be mixed with air in advance to form an oxygen-rich mixed gas before being connected to the oxygen cabin, and then the oxygen cabin is supplied with gas. In order to achieve the disinfection of the oxygen cabin, the pipeline system can also be provided with an ozone generator 16 electrically connected to the main control board 21 as a control device, so as to disinfect the cabin before or after the use of the oxygen cabin.

[0051] At the same time, in order to ensure the safety during the oxygen chamber filling process, it is necessary to monitor the status inside the oxygen chamber and the filling machine. Outside the inflation pipeline, multiple sensors and other devices need to be set in the space inside the filling machine shell. For example, it is necessary to set a temperature sensor (such as temperature sensor II 24) for monitoring the temperature inside the filling machine, especially the temperature of the compressor body after cooling. For another example, it is necessary to collect sensors for parameters such as temperature (temperature sensor I 18), pressure (pressure sensor 17), oxygen concentration (oxygen sensor II 19), and carbon dioxide concentration (carbon dioxide sensor 20) in the oxygen chamber. In addition, due to the different physiques of different people, parameters can be set before and after use through the display 23 that interacts with the main control board 21. In addition, a terminal information receiving unit 22 electrically connected to the main control board 21 can also be set to identify the user's identity information.

[0052] Figure 2 The three-dimensional structure diagram of a tank filling machine in a preferred embodiment of the present invention is schematically shown (part of the housing, part of the air compressor housing and all connecting pipes are omitted). Figure 2It can be seen that in this preferred embodiment, the exterior of the tank filling machine is a cubic shell 26, which is provided with an upper cover and a bottom plate, a display screen 23 is fixedly installed in the middle of the upper cover, and an air compressor cover 29 is fixedly installed on the upper part of the bottom plate for installing the air compressor 4. The bottom of the air compressor 4 is connected to the bottom of the air compressor cover 29 through a shock absorbing device. Two oxygen sensors, namely oxygen sensor I 15 and oxygen sensor II 19, are fixed on the sides of the air compressor cover 29.

[0053] An ozone generator 16 is fixed on the upper part of the air compressor housing 29 to facilitate the supply of ozone for disinfection of the oxygen chamber. At the same time, a main control board 21 is fixedly installed on the air compressor housing 29 through a vertical plate. The silencer 13 is fixedly installed on the rear side of the air compressor housing 29. The distribution valve 6 is fixed on the upper part of the ozone generator 16. The bacterial filter 13 and the fine filter device 2 are installed in the space above the air compressor housing 29 and below the top cover, connected to the relevant components through a connecting pipe, and then fixed by common components such as cable ties, bolts or glue. In addition to the display screen 23 on the top cover, there is also a terminal information receiving unit 22 for swiping a card to identify user information. In addition, a connector 28 is provided on the upper part of the shell 27 to facilitate connection with the oxygen chamber.

[0054] Figure 3 This is a schematic diagram showing the three-dimensional structure of the tank filling machine from another angle in a preferred embodiment of the present invention (part of the housing, part of the air compressor housing and all connecting pipes are omitted). Figure 3 It can be seen that in this preferred embodiment, two air intake grilles 31 are provided on the upper parts of the opposite sides of the shell 26, and the upper part of the air intake grilles 31 is the switch of the tank filling machine. The oxygen production unit containing the double molecular sieve tank 10 is fixedly installed at the rear of the air compressor cover 29. The lower part of the oxygen storage tank 11 is the cooler 5, and the lower part of the cooler 5 is the control valve 9. One side of the control valve 9 is a can-shaped silencer II 25 connected by a pipeline. The cooler 5 is provided with two interfaces, one is an inlet, which is connected to the air compressor 4, and the other is an outlet, which is connected to the tee II 30. The tee II 30 branches the air path to form two paths, one of which is connected to the air path control valve 7 (see Figure 2 ) forms a first air supply passage. The other is connected to the distribution valve 6. The bottom outlet of the distribution valve 6 is connected to the control valve 9, and the upper outlet is connected to the pipeline connected to the pressure relief valve (not shown) to form a second air supply passage.

[0055] The use process and principle of the above multi-mode inflation pipeline and tank filling machine are:

[0056] After the power is turned on, the air enters the filling machine through the air intake grille. After that, it passes through the primary filter device and the fine filter device, enters the silencer device I for silencing, and then enters the air compressor. The compressed air formed after compression by the air compressor flows out through the pipeline after being cooled by the cooler and enters the main pipeline. A tee is provided at the end of the main pipeline, and the compressed air is divided into two branches at the tee. One is the first air supply path provided with an air path control valve 7, which mainly provides the filling pressure for the oxygen cabin. The other one, after being distributed by the distribution valve, enters the second air supply path provided with a pressure relief valve, or enters the oxygen production unit.

[0057] The oxygen separated by the oxygen production unit flows out of the pressure regulating valve and enters the oxygen supply passage, while the nitrogen passes through the control valve of the oxygen production unit and is discharged after being silenced by the silencer II. An oxygen sensor I, a bacteria filter and an electronic flow meter are provided on the high-concentration oxygen supply passage to monitor the flow rate and oxygen concentration of the output oxygen and adsorb bacteria in the gas. In order to achieve the disinfection of the oxygen chamber, an ozone generator is provided in the filling pipeline of the filling machine to supply ozone.

[0058] At the same time, in order to realize the monitoring and control of the state of the oxygen chamber and the filling machine during the filling process, a main control board is provided as a control device. The main control board monitors the oxygen concentration, flow rate, temperature and other information flowing out of the filling machine through the information collection of various oxygen sensors, temperature sensors, pressure sensors, carbon dioxide pond sensors and other sensors and electronic flow meters and other devices, and collects technical parameters such as oxygen content, carbon dioxide content, pressure, temperature and so on in the oxygen chamber, so as to know the gas composition in the oxygen chamber. Then, by controlling the distribution valve, gas circuit control valve, ozone generator, control valve and other components, the gas composition in the oxygen chamber can be adjusted through multiple modes such as simple supply of air, supply of high-purity oxygen produced by the oxygen production unit, and supply of oxygen-rich mixed gas. At the same time, the inflation pipeline and the filling machine only use one air compressor to ensure both the inflation pressure and the supply of oxygen, which is conducive to reducing manufacturing costs, reducing product volume, and reducing product energy consumption.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
