Description

Technical Field

[0001] This utility model relates to the field of aquaculture oxygenation technology, and in particular to a floating aquaculture micro-nano bubble oxygenation float device. Background Technology

[0002] In existing aquaculture technologies, oxygenation is a crucial step in ensuring the healthy growth of aquatic organisms and increasing stocking density. Existing technologies, exemplified by CN203801515U, typically involve directly introducing oxygen into the aquaculture water using aerators. However, this method has significant limitations. Firstly, directly introducing oxygen often fails to ensure sufficient dissolution in the water, resulting in insufficient dissolved oxygen levels to meet the oxygen requirements of high-density aquaculture or specific growth stages of aquatic organisms. Secondly, direct oxygenation can lead to excessive concentration of oxygen in localized areas, while other areas suffer from oxygen deficiency, thus affecting the overall oxygen uniformity of the aquaculture water and hindering the balanced growth of aquatic organisms. Utility Model Content

[0003] The purpose of this invention is to provide a floating micro-nano bubble oxygenation float device for aquaculture. Utilizing water flow dynamics, it automatically draws in air and forms nanobubbles, which not only efficiently increases the dissolved oxygen content of the aquaculture water, meeting the needs of high-density aquaculture, but also achieves uniform oxygen distribution, avoiding the problem of uneven oxygen distribution in localized areas. Simultaneously, its energy-saving and consumption-reducing characteristics significantly lower operating costs, reduce energy consumption and interference with the aquaculture environment, and ensure overall environmentally friendly and pollution-free operation. It effectively improves the aquaculture environment, promotes the healthy growth of aquatic organisms, and enhances aquaculture efficiency and product quality, possessing both economic and ecological sustainability advantages.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0005] A floating aquaculture micro-nano bubble oxygenation float device includes:

[0006] The float ring and the mounting plate fixedly connected to the float ring are provided. The mounting plate is equipped with a bubble aeration component for micro-nano bubble aeration in aquaculture. The bottom of the mounting plate is also equipped with a propeller for the movement of the float ring.

[0007] The above-mentioned floating aquaculture micro-nano bubble oxygenation float device includes a bubble oxygenation component comprising a water inlet tank and a mixing tank fixedly connected to the mounting plate. The water inlet tank and the mixing tank are interconnected by a connecting pipe, and an air inlet pipe is installed on the connecting pipe. The cross-section of the connecting pipe is much smaller than the cross-section of the water inlet tank and the mixing tank.

[0008] In the above-mentioned floating aquaculture micro-nano bubble oxygenation float device, a water pump is installed on the side of the water inlet tank, and a water inlet pipe is installed at the bottom of the water pump.

[0009] In the above-mentioned floating aquaculture micro-nano bubble oxygenation float device, a filter component for water filtration is installed at the bottom of the water inlet pipe.

[0010] The above-mentioned floating aquaculture micro-nano bubble oxygenation float device includes a filter assembly comprising a filter shell installed at the bottom of the water inlet pipe, wherein a removable filter screen is installed inside the filter shell.

[0011] In the above-mentioned floating aquaculture micro-nano bubble oxygenation float device, the bottom of the filter shell is equipped with a fixing mesh plate for fixing the filter screen, and the fixing mesh plate is fixedly installed to the bottom of the filter shell by fixing bolts.

[0012] In the above-mentioned floating aquaculture micro-nano bubble oxygenation float device, an oxygenation pipe is fixedly connected to the end of the mixing tank away from the connecting pipe.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. This utility model realizes a floating aquaculture micro-nano bubble oxygenation float device, which automatically draws in air and forms nano bubbles using water flow dynamics. This not only efficiently increases the dissolved oxygen content of the aquaculture water, meeting the needs of high-density aquaculture, but also achieves uniform distribution of dissolved oxygen, avoiding the problem of uneven oxygen distribution in local water areas. At the same time, its energy-saving and consumption-reducing characteristics significantly reduce operating costs, reduce energy consumption and interference with the aquaculture environment, and the overall operation is environmentally friendly and pollution-free. It effectively improves the aquaculture environment, promotes the healthy growth of aquatic organisms, and improves aquaculture efficiency and product quality, possessing both economic and ecological sustainable advantages.

[0015] 2. High-efficiency oxygenation: This invention uses a water pump to draw aquaculture water into the inlet pipe and transport it to the inlet tank, then through a specially designed connecting pipe to the mixing tank. Because the diameter of the connecting pipe is much smaller than the cross-section of the inlet and mixing tanks, the water flow speed increases and the pressure decreases as it passes through the connecting pipe, automatically drawing in air from the air inlet pipe. This design allows for thorough mixing of air and water, and as the air flows into the mixing tank, cavitation occurs during the pressure change, forming numerous microbubble nuclei—the initial form of nanobubbles. These nanobubbles significantly increase the contact area between water and air, substantially improving the dissolved oxygen content of the aquaculture water and meeting the needs of high-density aquaculture.

[0016] 3. Uniform dissolved oxygen: Compared with the method of directly introducing oxygen, the present invention can generate nanobubbles through the automatic mixing of water and air and cavitation, which can be evenly distributed in the entire aquaculture water body, avoiding the problem of excessive concentration or lack of oxygen in local water areas, and ensuring the balanced growth of aquatic organisms.

[0017] 4. Energy saving and consumption reduction: This invention utilizes water flow power to automatically draw in air, eliminating the need for additional oxygenation equipment or energy consumption, thus reducing operating costs. Simultaneously, the formation and distribution of nanobubbles is natural and efficient, minimizing interference with the aquaculture environment.

[0018] 5. Environmentally Friendly and Sustainable: By increasing the dissolved oxygen content in the aquaculture water, this invention helps improve the aquaculture environment, reduces aquatic organism diseases and mortality caused by oxygen deficiency, thereby improving aquaculture efficiency and product quality. Furthermore, the operation of this device does not produce harmful substances, meeting the requirements of environmental protection and sustainable development. Attached Figure Description

[0034] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] Please refer to Figures 1 to 6 As shown, an embodiment of this utility model provides a floating aquaculture micro-nano bubble oxygenation float device, including: a float ring 1 and a mounting plate 2 fixedly connected to the float ring 1. The mounting plate 2 is equipped with a bubble oxygenation component 3 for aquaculture micro-nano bubble oxygenation, and a spiral propeller 4 for the movement of the float ring 1 is also installed at the bottom of the mounting plate 2.

[0036] By adopting the above-mentioned technical solution, air is automatically drawn in and nanobubbles are formed using water flow dynamics. This not only efficiently increases the dissolved oxygen content of the aquaculture water, meeting the needs of high-density aquaculture, but also achieves uniform distribution of dissolved oxygen, avoiding the problem of uneven oxygen distribution in local water areas. At the same time, its energy-saving and consumption-reducing characteristics significantly reduce operating costs, reduce energy consumption and interference with the aquaculture environment, and ensure that the overall operation is environmentally friendly and pollution-free. It effectively improves the aquaculture environment, promotes the healthy growth of aquatic organisms, and enhances aquaculture efficiency and product quality, thus possessing both economic and ecological sustainability advantages.

[0037] To optimize the mixing efficiency of water and air, in this embodiment, the bubble oxygenation component 3 includes a water inlet tank 301 and a mixing tank 3011 fixedly connected to the mounting plate 2. The water inlet tank 301 and the mixing tank 3011 are interconnected by a connecting pipe 302, and an air inlet pipe 303 is installed on the connecting pipe 302. The cross-section of the connecting pipe 302 is much smaller than the cross-section of the water inlet tank 301 and the mixing tank 3011. This design allows the water flow to accelerate significantly and decrease in pressure when passing through the connecting pipe 302, thereby automatically drawing in air from the air inlet pipe 303. This achieves efficient mixing of water and air, providing a foundation for the subsequent formation of nanobubbles.

[0038] In order to achieve automatic intake of aquaculture water and output of oxygenated water, in this embodiment: a water pump 304 is installed on the side of the water inlet tank 301, a water inlet pipe 3041 is installed at the bottom of the water pump 304, and an oxygenation pipe 306 is fixedly connected to the end of the mixing tank 3011 away from the connecting pipe 302.

[0039] To prevent impurities from entering the aeration system and ensure stable system operation, in this embodiment: a filter assembly 305 for water filtration is installed at the bottom of the inlet pipe 3041. The filter assembly 305 includes a filter housing 3051 installed at the bottom of the inlet pipe 3041, and a removable filter screen 3052 is installed inside the filter housing 3051. The filter screen 3052 effectively prevents impurities in the aquaculture water from entering the aeration system, avoiding wear and blockage of system components by impurities, and ensuring stable system operation. At the same time, the removable filter screen 3052 design facilitates regular cleaning and replacement, reducing maintenance costs.

[0040] To ensure the secure installation and convenient replacement of the filter screen 3052, in this embodiment, a fixing plate 3053 for fixing the filter screen 3052 is installed at the bottom of the filter housing 3051. The fixing plate 3053 is fixedly installed at the bottom of the filter housing 3051 by fixing bolts 3054. The combination of the fixing plate 3053 and the fixing bolts 3054 ensures the secure installation of the filter screen 3052 in the filter housing 3051, preventing the filter screen 3052 from shifting or falling off during operation. At the same time, this design also facilitates quick disassembly and replacement of the filter screen 3052 when needed, improving maintenance efficiency.

[0041] The working principle of this invention is as follows: Driven by a water pump 304, aquaculture water is drawn in through the inlet pipe 3041 and transported to the inlet tank 301. Subsequently, the water flows through the connecting pipe 302 to the mixing tank 3011. Because the diameter of the connecting pipe 302 is much smaller than the cross-section of the inlet tank 301 and the mixing tank 3011, the water flow velocity increases dramatically when passing through the connecting pipe 302, resulting in a significant decrease in the internal pressure of the connecting pipe 302. This pressure change allows external air to be automatically drawn into the connecting pipe 302 from the air inlet pipe 303, where it is thoroughly mixed with the water flow. When the water flows from the connecting pipe 302 into the mixing tank 3011, the flow velocity gradually decreases, and the pressure gradually recovers. However, because a large amount of gas has been incorporated into the liquid, cavitation occurs during the pressure change, forming a large number of tiny bubble nuclei, i.e., the initial form of nanobubbles. These nanobubbles can greatly increase the contact area between water and air, significantly improving the dissolved oxygen content of the aquaculture water. Finally, the oxygenated water is transported back to the aquaculture area through oxygenation pipe 306, providing sufficient oxygen for aquatic organisms and promoting their healthy growth.

[0042] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
