Description

Technical Field

[0001] This utility model relates to the field of oxygen discs, and more particularly to a dual oxygen supply oxygen disc structure. Background Technology

[0002] In aquaculture, oxygenation discs are indispensable key equipment. During aquaculture, the dissolved oxygen level in the water directly affects the growth rate, feed conversion rate, and survival rate of aquatic organisms. Traditional oxygenation discs primarily rely on air-filled oxygen pipes to provide oxygen to the water. These discs typically consist of microporous aeration discs or similar aeration devices, using blowers to deliver oxygen from the air into the water, thereby increasing the dissolved oxygen level.

[0003] However, existing oxygenation discs relying solely on air oxygen pipes have significant limitations. First, the oxygen content in the air is only about 21%, meaning the concentration of oxygen obtained from the air is relatively low, limiting dissolved oxygen efficiency. In high-density aquaculture or when aquatic organisms have high oxygen demands, simple air oxygenation often fails to meet the large oxygen requirements of the water body, easily leading to localized hypoxia and affecting the health and growth of aquatic organisms. Second, in the event of a sudden power outage or equipment failure, an oxygenation system relying solely on air oxygen pipes may not be able to provide sufficient oxygen in time, increasing the risk of aquaculture problems. Furthermore, in some special circumstances, such as when a rapid increase in dissolved oxygen levels is needed, a single air oxygenation method has a slow response time and cannot quickly meet the dissolved oxygen requirements of the water body. Therefore, developing a dual-supply oxygenation disc structure capable of simultaneously providing both liquid and gaseous oxygen is of great significance. Utility Model Content

[0004] Therefore, it is necessary to provide a dual-oxygenation-supply oxygen disc structure to solve the problem that the response speed of a single air oxygenation method is too slow and cannot quickly meet the dissolved oxygen demand of the water body.

[0005] To achieve the above objectives, this utility model provides a dual-supply oxygen disc structure, including a support, an air oxygen pipe, a liquid oxygen pipe, a first external connecting pipe, and a second external connecting pipe; the support includes an upper plate surface and at least two supporting legs; the upper plate surface and the supporting legs form an internal space, and both the air oxygen pipe and the liquid oxygen pipe are arranged in a ring within the internal space, with multiple aeration structures provided on the walls of both the air oxygen pipe and the liquid oxygen pipe; the liquid oxygen pipe is connected to a liquid oxygen source through the first external connecting pipe, and a vaporizer is provided on the first external connecting pipe; the air oxygen pipe is connected to an air source through the second external connecting pipe.

[0006] Furthermore, the liquid oxygen pipe is covered with an insulating outer layer, which does not cover the aeration structure.

[0007] Furthermore, the upper disk surface has a mesh structure.

[0008] Furthermore, the support leg has a U-shaped structure.

[0009] Furthermore, the air oxygen pipe is arranged in a ring around the liquid oxygen pipe.

[0010] Furthermore, the first external connecting pipe is connected to the liquid oxygen pipe via a first tee connector; or

[0011] The second external pipe is connected to the air oxygen pipe via a second tee connector.

[0012] Furthermore, the first external connector and the second external connector are plastic tubing.

[0013] Furthermore, the air source is an air pump.

[0014] Furthermore, the liquid oxygen source is a liquid oxygen tank.

[0015] Furthermore, the support leg is a retractable structure.

[0016] Unlike existing technologies, the above technical solution includes a support frame, an air oxygen pipe, a liquid oxygen pipe, a first external connecting pipe, and a second external connecting pipe. The support frame consists of an upper plate and at least two supporting legs, forming an internal space. The air oxygen pipe and the liquid oxygen pipe are arranged in a ring within the internal space, with multiple aeration structures on the pipe walls. The liquid oxygen pipe is connected to a liquid oxygen source via the first external connecting pipe, which is equipped with a vaporizer. The air oxygen pipe is connected to an air source via the second external connecting pipe. When the oxygenation disc is working, air from the air source is introduced into the water body through the aeration structures of the air oxygen pipe. Before being introduced into the water body through the aeration structures of the liquid oxygen pipe, the liquid oxygen from the liquid oxygen source is converted into gaseous oxygen by the vaporizer, simultaneously providing both liquid and gaseous oxygen, effectively increasing the dissolved oxygen content of the water body and meeting the needs of high-density aquaculture.

[0033] Please see Figures 1 to 5 This embodiment provides a dual-supply oxygen disc structure, including a support 10, an air oxygen pipe 21, a liquid oxygen pipe 22, a first external pipe 31, and a second external pipe 32. The support 10 includes an upper plate surface 101 and at least two supporting legs 102. The upper plate surface 101 and the supporting legs 102 form an internal space. The air oxygen pipe 21 and the liquid oxygen pipe 22 are both arranged in a ring within the internal space. The pipe walls of the air oxygen pipe 21 and the liquid oxygen pipe 22 are provided with multiple aeration structures 40. The liquid oxygen pipe 22 is connected to a liquid oxygen source through the first external pipe 31, and a vaporizer is provided on the first external pipe 31. The air oxygen pipe 21 is connected to an air source through the second external pipe 32.

[0034] The upper plate 101 can adopt a mesh structure, which ensures uniform oxygen release and reduces water resistance. Stainless steel is a common material, offering good corrosion resistance and strength, and can withstand the humid and chemically corrosive conditions of aquaculture environments. The support feet 102 can be U-shaped, also made of stainless steel. The U-shaped structure provides strong support while reducing obstruction to water flow. Its main function is to fix the position of the oxygenation plate, prevent it from drifting in the water, and protect it from water flow impacts and collisions with cultured organisms.

[0035] Both the air oxygen pipe 21 and the liquid oxygen pipe 22 can be made of metal, such as stainless steel, which has good corrosion resistance and mechanical strength, and can withstand water pressure and pressure changes during oxygen delivery. The air oxygen pipe 21 is mainly used to output air into the water; its annular arrangement allows for uniform air distribution in the water, increasing the contact area between oxygen and water. The liquid oxygen pipe 22 is used to output gaseous pure oxygen into the water; its annular arrangement allows for a more uniform bubble distribution of gaseous pure oxygen in the water, enhancing the dissolved oxygen effect.

[0036] The aeration structure 40 can be in the form of micropores or nozzles. The micropore aeration structure 40 typically consists of small holes with a diameter of less than 2 mm, which can generate a large number of tiny bubbles, increasing the contact area between oxygen and water and improving dissolved oxygen efficiency. The nozzle aeration structure 40, through a specific design, releases oxygen into the water in the form of a high-speed jet, utilizing the turbulence of the jet to promote oxygen dissolution.

[0037] A schematic diagram of the microporous aeration structure 40 of the liquid oxygen pipe 22 can be found here. Figure 4 The same applies to the air oxygen tube 21.

[0038] The first external pipe 31 and the second external pipe 32 are made of flexible plastic material, such as PVC, which facilitates pipe connection and layout, and also has good corrosion resistance and aging resistance. The liquid oxygen pipe 22 is connected to a liquid oxygen source via the first external pipe 31. The liquid oxygen source can be a liquid oxygen tank or a liquid oxygen generator, etc. A vaporizer is installed on the first external pipe 31. The vaporizer works by converting liquid oxygen into gaseous oxygen through heating or ambient temperature. Vaporizers can refer to existing technologies, such as the SWEP B50 and AlfaLaval HX-T100. These vaporizers typically have high-efficiency heat exchange performance, enabling them to convert liquid oxygen into gaseous oxygen in a short time, ensuring a stable oxygen supply.

[0039] The air oxygen pipe 21 is connected to an air source through the second external pipe 32. The air source can be an air pump or a blower, such as a common centrifugal air pump or a Roots blower. These devices can draw in external air and deliver it to the water body through the air oxygen pipe 21 to provide oxygen to the water body.

[0040] This utility model relates to a dual-supply oxygenation disc structure, including a support 10, an air oxygen pipe 21, a liquid oxygen pipe 22, a first external connecting pipe 31, and a second external connecting pipe 32. The support 10 consists of an upper plate surface 101 and at least two supporting legs 102, forming an internal space. The air oxygen pipe 21 and the liquid oxygen pipe 22 are arranged in a ring within the internal space, with multiple aeration structures 40 on the pipe walls. The liquid oxygen pipe 22 is connected to a liquid oxygen source via the first external connecting pipe 31, and the first external connecting pipe 31 is equipped with a vaporizer. The air oxygen pipe 21 is connected to an air source via the second external connecting pipe 32. When the oxygenation disc is in operation, air from the air source is input into the water body through the aeration structures 40 of the air oxygen pipe 21. Before being input into the water body through the aeration structures 40 of the liquid oxygen pipe 22, the liquid oxygen from the liquid oxygen source is first converted into gaseous oxygen by the vaporizer, simultaneously providing both liquid and gaseous oxygen, effectively increasing the dissolved oxygen content of the water body and meeting the needs of high-density aquaculture.

[0041] In some embodiments, see Figure 5 The liquid oxygen pipe 22 is covered with an insulating outer layer 50, which does not cover the aeration structure 40. The insulating outer layer covering the liquid oxygen pipe 22 can be made of materials with good thermal insulation properties, such as cotton, polyurethane foam, or fiberglass. When the aeration structure 40 uses micropores, the insulating outer layer is wrapped around the non-aeration area of ​​the liquid oxygen pipe 22 using a specific process, such as uniformly coating or wrapping insulating material around other parts of the pipe body, ensuring that the micropores are fully exposed so that liquid oxygen can be smoothly released and vaporized from the micropores. If the aeration structure 40 is a nozzle, the insulating outer layer reserves corresponding holes or channels at the nozzle installation location to ensure the nozzle can work normally, while simultaneously insulating other parts of the liquid oxygen pipe 22 to reduce heat loss during liquid oxygen transportation, ensuring that the liquid oxygen remains liquid before reaching the aeration structure 40, and improving vaporization efficiency.

[0042] In some embodiments, the air oxygen pipe 21 is arranged around the liquid oxygen pipe 22. This arrangement allows the air oxygen pipe 21 to cover a larger water area, resulting in a greater air supply and providing more sufficient oxygen to the water. In aquaculture, especially in high-density environments, aquatic organisms have a high oxygen demand. This arrangement of the air oxygen pipe 21 ensures a uniform distribution of oxygen in the water, increasing dissolved oxygen levels and meeting the growth needs of aquatic organisms. Simultaneously, the outer air oxygen pipe 21 provides some protection, reducing the impact of water flow on the liquid oxygen pipe 22 and ensuring its stable operation.

[0043] In some embodiments, the first external pipe 31 is connected to the liquid oxygen pipe 22 via a first tee connector 61; or the second external pipe 32 is connected to the air oxygen pipe 21 via a second tee connector 62. One of the tee connectors 61 is connected to the first external pipe 31, and the other two are connected to both ends of the liquid oxygen pipe 22. This design allows liquid oxygen to be evenly distributed into the annular path of the liquid oxygen pipe 22 after entering through the first external pipe 31, improving the delivery efficiency of liquid oxygen and ensuring that the vaporized oxygen is evenly released into the water. Similarly, one of the tee connectors 62 is connected to the second external pipe 32, and the other two are connected to both ends of the air oxygen pipe 21, allowing air to smoothly enter the air oxygen pipe 21 and flow in the annular path, optimizing air distribution and enhancing the oxygen supply capacity of the oxygenation disc.

[0044] In some embodiments, the support foot 102 is a telescopic structure. The telescopic structure of the support foot 102 can be implemented in various ways. A common design is a telescopic structure, where the support foot 102 is designed as a multi-segmented tube, with each segment adjusted and fixed by built-in springs or threads, such as a common telescopic tube structure. Another design is a spiral telescopic structure, where a spiral guide rail and slider are installed inside the support foot 102. Rotating the support foot 102 causes the slider to move along the spiral guide rail, thus achieving telescopic movement. This structure is similar to the principle of a spiral jack, allowing for precise adjustment of the height of the support foot 102. Both of these telescopic support foot structures can adapt to ponds or aquaculture areas with varying water depths in different aquaculture environments. By adjusting the height of the bracket 10, the oxygenation disc can be placed at a certain height above the pond bottom, allowing oxygen to diffuse better to all levels of the water, improving the oxygenation effect, while simultaneously preventing the oxygenation disc from contacting debris on the pond bottom, extending the lifespan of the oxygenation disc.

[0045] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
