Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically a circulating micro-flow high dissolved oxygen seedling pond. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process of growing aquatic products from seedlings under artificial feeding and management. In a broader sense, it can also include the enhancement of aquatic resources. In aquaculture, seedling ponds are usually used to cultivate biological seedlings.

[0003] Because the nursery pond has a small internal space and a large number of cultured organisms, the oxygen content in the water decreases during the culture process, making it impossible to supply oxygen effectively. In addition, the water cannot flow in a timely manner, leading to the accumulation of impurities and waste. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a circulating micro-flow high dissolved oxygen seedling tank, which solves the problems of decreased water oxygen content and ineffective oxygen supply during the breeding process, as well as the accumulation of impurities and waste due to the inability of water flow to flow in a timely manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating micro-flow high dissolved oxygen seedling tank, comprising a seedling tank body, a water injection connection pipe connected to the top of the seedling tank body, a drainage connection pipe connected to one side of the seedling tank body, multiple baffles connected inside the seedling tank body, connection holes opened on both sides of the seedling tank body, fixed pipes installed on both sides of the seedling tank body, a liquid pump fixedly installed on one side of the seedling tank body, and an air pump fixedly installed on the seedling tank body;

[0006] A curved pipe is connected to the main body of the seedling pond. A filter box is set on one side of the main body of the seedling pond. An installation pipe is installed on the filter box. Multiple air supply pipes are set inside the curved pipe. Microporous oxygenation discs are connected to both ends of the air supply pipes. An opening is opened at the bottom of the installation pipe. A partition is connected to the installation pipe and the filter box. An activated carbon layer is set on one side of the filter box. A biosphere layer is set on the other side of the filter box.

[0007] As a further embodiment of this utility model: the air pump is connected to a connecting pipe, the connecting pipe is interconnected with multiple air supply pipes, and the liquid pump is connected to a fixed pipe and a curved pipe on one side of the main body of the seedling pool.

[0008] As a further embodiment of this utility model: the gas transmission pipe is U-shaped, the curved pipe is serpentine, and the U-shaped fork end of the gas transmission pipe is located inside the curved pipe, and a pressure relief valve is installed on the curved pipe.

[0009] As a further embodiment of this utility model: the fixing pipe is designed in a bifurcated manner and the bifurcated end is fixedly connected to the connecting hole. One end of the fixing pipe is connected to a baffle. One end of the installation pipe is connected to the fixing pipe on one side of the main body of the seedling pool, and the other end of the installation pipe is connected to the curved pipe.

[0010] As a further embodiment of this utility model: there are two baffles in total, and the two baffles are designed in a centrally symmetrical manner, and the internal space of the main body of the seedling pool is divided into an S-shape by the two baffles.

[0011] As a further embodiment of this utility model: the installation pipe is connected to the filter box through the port, the partition is disposed between the activated carbon layer and the biosphere layer, and the activated carbon layer and the biosphere layer below the partition are in contact and connected to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This circulating micro-flow high dissolved oxygen seedling tank, through the installation of baffles, air pumps, connecting pipes, air supply pipes, microporous aeration discs, and curved pipes, uses baffles to block water, allowing the water to flow along an S-shaped space when the liquid pump draws it out, thereby improving the breeding effect. When the liquid pump draws water from the main body of the seedling tank and the water flows from one end of the installation pipe into the curved pipe, the air pump delivers gas to the air supply pipe through the connecting pipe, and uses the microporous aeration disc to generate bubbles, thereby increasing the oxygen content of the water flowing in the curved pipe. This method of not directly injecting oxygen into the main body of the seedling tank reduces the impact of bubbles on the seedlings and water flow, and increases the oxygen content of the water to avoid seedling hypoxia.

[0014] 2. This circulating micro-flow high dissolved oxygen seedling tank, through the installation pipe, filter box, baffle, inlet, activated carbon layer and biosphere layer, when the liquid pump draws water from the main body of the seedling tank, the water flow first enters the installation pipe and flows into the filter box through the inlet. Due to the baffle, the water flow first penetrates into the biosphere layer, which decomposes toxic substances such as ammonia nitrogen and nitrite in the water. Then, the water flow permeates into the activated carbon layer through the gap between the filter box and the baffle, thereby adsorbing organic pollutants in the water and reducing the impact of water quality fluctuations on seedlings.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a circulating micro-flow high dissolved oxygen seedling tank, including a seedling tank body 1, a water injection connection pipe 2 connected to the top of the seedling tank body 1, a drainage connection pipe 3 connected to one side of the seedling tank body 1, and multiple baffles 4 connected inside the seedling tank body 1. There are two baffles 4 in total, and the two baffles 4 are designed in a central symmetrical manner. The internal space of the seedling tank body 1 is divided into an S-shape by the two baffles 4. The baffles 4 enable the water to flow in a directional manner, and the flowing water can prevent local hypoxia. The water injection connection pipe 2 and the drainage connection pipe 3 can facilitate the user to change the water.

[0022] The main body 1 of the seedling pool has connection holes 5 on both sides. Fixed pipes 6 are installed on both sides of the main body 1 of the seedling pool. The fixed pipes 6 are designed with a forked shape and the forked ends are fixedly connected to the connection holes 5. A baffle 20 is connected to one end of the fixed pipe 6. One end of the installation pipe 11 is connected to the fixed pipe 6 on one side of the main body 1 of the seedling pool, and the other end of the installation pipe 11 is connected to the curved pipe 9. The baffle 20 at one end of the fixed pipe 6 can play a blocking role, thereby preventing seedlings from accidentally entering the fixed pipe 6.

[0023] A liquid pump 7 is fixedly installed on one side of the main body 1 of the seedling pool, and an air pump 8 is fixedly installed on the main body 1 of the seedling pool. A connecting pipe 18 is connected to the air pump 8, and the connecting pipe 18 is interconnected with multiple air supply pipes 12. The liquid pump 7 is connected to a fixed pipe 6 and a curved pipe 9 on one side of the main body 1 of the seedling pool. The liquid pump 7 draws water out of the main body 1 of the seedling pool, thereby promoting water flow and allowing the water to flow into the filter box 10 for filtration, so as to achieve short-term recycling.

[0024] A curved pipe 9 is connected to the main body 1 of the seedling pond. A filter box 10 is set on one side of the main body 1 of the seedling pond. An installation pipe 11 is installed on the filter box 10. Multiple air supply pipes 12 are set inside the curved pipe 9. The air supply pipes 12 are U-shaped, and the curved pipe 9 is serpentine. The U-shaped fork ends of the air supply pipes 12 are set inside the curved pipe 9. A pressure relief valve 19 is installed on the curved pipe 9. The water in the curved pipe 9 is oxygenated through the air supply pipes 12 and the microporous oxygenation disc 13 to increase the oxygen content of the water. At the same time, the pressure relief valve 19 can relieve the pressure in the curved pipe 9 to prevent excessive pressure inside the curved pipe 9 and promote normal water flow.

[0025] The air supply pipe 12 is connected to microporous oxygenation discs 13 at both ends. An opening 14 is provided below the installation pipe 11. The installation pipe 11 and the filter box 10 are connected by a partition 15. An activated carbon layer 16 is provided on one side of the filter box 10, and a biosphere layer 17 is provided on the other side of the filter box 10. The installation pipe 11 is connected to the filter box 10 through the opening 14. The partition 15 is located between the activated carbon layer 16 and the biosphere layer 17, and the activated carbon layer 16 and the biosphere layer 17 are in contact and connected below the partition 15. The activated carbon layer 16 and the biosphere layer 17 filter impurities in the water, thereby reducing pollutants in the water that flows back into the main body of the seedling pond 1.

[0026] The working principle of this utility model is as follows:

[0027] The water in the main body 1 of the seedling pond is drawn out by the liquid pump 7, and flows from the fixed pipe 6 on one side into the installation pipe 11, and then into the filter box 10 through the opening 14. Due to the obstruction of the partition 15, the water flow first penetrates into the biological ball layer 17, which decomposes the toxic substances such as ammonia nitrogen and nitrite in the water. Then, the water flows through the gap between the filter box 10 and the partition 15 into the activated carbon layer 16, thereby adsorbing the organic pollutants in the water. After that, the water flows into the curved pipe 9. At this time, the air pump 8 delivers gas to the air supply pipe 12 through the connecting pipe 18, and generates bubbles using the microporous oxygenation plate 13, thereby increasing the oxygen content of the water flowing in the curved pipe 9. Finally, the water flows back into the main body 1 of the seedling pond from the fixed pipe 6 on the other side, so that the water in the main body 1 of the seedling pond can flow.
