Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to a gas storage mechanism of a molecular sieve oxygen production system. Background Art

[0002] Molecular sieve oxygen concentrator is a commonly used oxygen production equipment. It obtains high-purity oxygen by conveying air through high pressure to an adsorption tower to remove nitrogen, carbon dioxide and other components. When in use, the molecular sieve oxygen concentrator also needs to be used in conjunction with air compressors, cooling systems, gas storage tanks and other equipment to form a system for pressurizing, cooling, filtering, and storing the air for use in the oxygen concentrator. However, these mechanisms in the oxygen production system are usually installed and arranged independently, which makes the entire oxygen production system occupy a large area, and it is not convenient to move and use.

[0003] In order to make the molecular sieve oxygen generator more convenient to use, the inventor designed a compact oxygen production system, which effectively reduced the volume of the oxygen production system by rationally utilizing and arranging the compression, cooling, gas storage, oxygen production and other mechanisms. In order to cater to this oxygen production system, the inventor designed a gas storage mechanism for the molecular sieve oxygen production system. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a gas storage mechanism of a molecular sieve oxygen production system.

[0005] The technical solution of this utility model is as follows:

[0006] A gas storage mechanism of a molecular sieve oxygen production system is applied to a compactly arranged oxygen production system, wherein the oxygen production system comprises a box body, the gas storage mechanism is located at one side of the lower part of the box body, and is isolated from other areas by a baffle, and comprises a plurality of gas storage tanks;

[0007] A plurality of gas storage tanks are arranged horizontally side by side and are interconnected, and fixing frame assemblies for fixing the positions of the gas storage tanks are arranged above and below the gas storage tanks to fix the gas storage tanks on the box body;

[0008] The plurality of gas storage tanks are provided with air inlets and air outlets, and the air inlets and air outlets are respectively located on different gas storage tanks.

[0009] In the box, various mechanisms for air treatment before oxygen production are arranged above the gas storage mechanism, including an air compressor. The gas storage tank is used to store the high-pressure air in the oxygen production system that has been compressed by the air compressor and filtered, cooled, etc., and the high-pressure air eventually flows to the molecular sieve oxygen generator for oxygen production.

[0010] The gas storage mechanism provided in the present application arranges a plurality of gas storage tanks side by side, thereby effectively reducing the height of the box while meeting the gas storage requirements, thereby reducing the height of the entire oxygen production system assembly.

[0011] In addition, compared with a single tank, multiple gas storage tanks have better overall stability and higher structural strength. At the same time, they can serve as the base of air compressors and other mechanisms, playing a role of stable support.

[0012] In the present application, the gas storage mechanism preferably includes two gas storage tanks, the length directions of the two gas storage tanks are parallel to the long sides of the box body, and are arranged side by side along the width direction of the box body, which can simplify the structure as much as possible while ensuring the gas storage capacity requirements.

[0013] In the above solution, the opposite sides of the two gas tanks are connected through a connecting pipe, and the two ends of the connecting pipe are preferably connected to the center positions of the opposite sides of the two gas tanks to simplify the overall structure and make the connection between the two gas tanks more direct.

[0014] In addition, the two gas tanks are provided with a total of an air inlet and an air outlet, which are respectively located at the ends of the two gas tanks, and are preferably located at one end of the gas tank close to the side wall of the box body, which can simplify the pipeline connection of the gas tank and facilitate the layout of the pipeline.

[0015] In the present application, the two gas storage tanks are cylindrical and have the same shape to enhance the structural strength of the gas storage mechanism.

[0016] In order to stably support and fix the position of the gas tank, the fixing frame assembly includes four fixing frames, which are symmetrically arranged up and down and clamp the two gas tanks. The fixing frame at the lower position is fixed to the box body by bolts, and the fixing frame at the upper position is fixed to the baffle by bolts.

[0017] In order to make the clamping of the gas tank more stable and reliable, the fixing frame is provided with two arc grooves matching with the cylindrical surface of the gas tank along its length direction. When clamping, the two gas tanks are respectively clamped in the arc grooves to fix the position of the gas tanks.

[0018] In addition, a condensate drain port may be provided at the bottom of the gas storage tank to discharge condensate that may be generated in the tank body.

[0019] In the present application, a cooling air inlet is provided at the bottom of the gas storage mechanism, and a cooling air outlet is provided on the baffle plate at the top, and the cooling air outlet corresponds to the inlet connected to the air compressor. By utilizing the principle of cold air descending, low-temperature air enters from the bottom, and the air flows through the outside of the gas storage tank, which can cool the gas storage tank. Finally, the air enters the air compressor from the cooling air outlet for compression. In this process, the air flow power is provided by the air compressor.

[0020] The utility model provides a gas storage mechanism for a molecular sieve oxygen production system, which can effectively reduce the overall height of the oxygen production system and enhance the structural strength of the gas storage mechanism by horizontally arranging a plurality of gas storage tanks.

[0021] In addition, by utilizing the characteristic of low temperature of low-position air, low-position air is used as the air source of the air compressor, and the air is allowed to flow in from the bottom of the air storage mechanism, pass through the outside of the air tank and enter the air compressor. The space of the air storage mechanism is used as a channel for the flow of air source of the air compressor, and the air is also used to cool the air tank, saving space for the air storage system and making rational use of resources.

[0034] The gas storage mechanism further includes a fixing frame assembly 3 for fixing the gas storage tank 2 on the box body 1 .

[0035] In this embodiment, the fixing frame assembly 3 includes four fixing frames 31 . The fixing frames 31 are in an elongated shape, and the length direction thereof is perpendicular to the length direction of the gas storage tank 2 . The length thereof is greater than or equal to the total width of the multiple gas storage tanks 2 after being connected.

[0036] The four fixing frames 31 are arranged in pairs and clamped near the two ends of the multiple gas storage tanks 2. The two fixing frames 31 in each pair are symmetrically arranged up and down.
