Description

Technical Field

[0001] The present invention relates to the technical field of oxygen supply for aquaculture water bodies, and specifically to an oxygenation device for increasing the land-based culture carrying capacity of perch. Background Technique

[0002] With the continuous growth of the market demand for perch, land-based culture in the southwestern mountainous areas has been widely applied due to its advantages such as convenience, strong controllability, and high land utilization rate. However, the land-based culture of perch in this region still faces a bottleneck in carrying capacity. Traditional culture equipment and methods are difficult to further improve the perch culture carrying capacity under the limited culture conditions in the mountains, while also ensuring the healthy growth of perch and the stability of water quality. The main problems are that when culturing at high density, the dissolved oxygen in the water is insufficient, and harmful substances such as ammonia nitrogen accumulate, which easily leads to the spread of diseases. In addition, uneven feeding results in inconsistent growth of perch, further restricting the culture carrying capacity.

[0003] In the prior art, at the same culture density, there are many oxygenation methods. However, all existing oxygenation methods have various problems. Using liquid oxygen or an oxygen generator as the gas supply source and a nano-aeration disk, the utilization rate is generally lower than 60%, which is relatively wasteful of oxygen and has a high cost; using a Roots blower or a vortex blower for oxygenation, the dissolved oxygen saturation is relatively low, unable to meet the requirements of high-density culture, and the water body exchange demand is relatively large for maintaining the aquaculture water quality. Similarly, the cost is high and the output is low; if it is oxygenation for flow-through culture, it cannot be applied to most areas with resource limitations and where the water source is not very abundant, thus restricting the development of the aquaculture industry and the shortage of aquatic product supply; there are a large number of cases of losses caused by hypoxia during the annual aquaculture process. In this context, there is an urgent need to scientifically, routinely, and standardizedly solve the oxygenation problem. Summary of the Invention

[0004] The present invention provides an oxygenation device for increasing the land-based culture carrying capacity of perch, which solves the problems raised in the above background technique.

The upper end of the water pump 1 is fixedly connected to a water pump outlet pipe 13.

[0021] Please refer to Figure 2 And Figure 6 , the upper end of the gas-liquid fusion pipe 3 is fixedly installed with a first elbow pipe 14 located above the diverter 2. The right end of the first elbow pipe 14 is fixedly connected to a second elbow pipe 15. The lower end of the second elbow pipe 15 is fixedly installed with a vertical pipe 16, and the lower end of the vertical pipe 16 is movably connected to the upper end of the water pump 1. The installation of the vertical pipe 16 serves to connect the second elbow pipe 15 and the water pump 1.

[0022] The left side of the first high-oxygen water outlet pipe 4 is fixedly installed with a communicating pipe 18. The installation of the communicating pipe 18 serves to connect the first high-oxygen water outlet pipe 4 and the second high-oxygen water outlet pipe 5. The lower end on the right side of the communicating pipe 18 is fixedly provided with an inspection port 17. The left end of the communicating pipe 18 is fixedly connected to the right end of the second high-oxygen water outlet pipe 5.

[0023] Please refer to Figure 4 And Figure 5 , the left end of the extension pipe 9 is fixedly installed with a first flange 19 located on the right side of the water pump inlet pipe 11. The inner wall of the first flange 19 is threadedly sleeved with a fastening bolt 21. The installation of the first flange 19 provides support and space for the installation of the fastening bolt 21. The left side of the first flange 19 is fixedly installed with an outer ring block 20 located inside the fastening bolt 21.

[0024] On the right side of the water inlet pipe 11 of the water pump, a second flange 24 is fixedly installed. One end of the second flange 24 away from the water inlet pipe 11 of the water pump is fixedly connected with an inner ring block 22.

[0027] In summary, for this oxygenation device for aquaculture, during use, first, install the water pump 1 and the second high-oxygen outlet pipe 5 outside the pond, and install the gas-liquid fusion pipe 3 inside the pond. Connect the power supply of the water pump 1 and start the water pump 1. The water body flows through the inside of the extension pipe 9 and then through the inside of the water inlet pipe 11 of the water pump and then flows into the inside of the water pump 1. The water inside the extension pipe 9 is filtered by the filter plate 10, so that the water body is separated from the impurities and prevents the impurities from entering the inside of the water pump 1. Then, the water body flowing into the inside of the water pump 1 flows to the gas-liquid fusion pipe 3. First, it passes through the shunt 2 and flows into the inside of the gas-liquid fusion pipe 3. The water body is fully fused with the adjustable pure oxygen transported from the air inlet 7, the air flow meter, and the nano oxygen diffuser 6. If there is excess un-fused gas, it can be fused again through the exhaust port 8, the air return valve, and the exhaust valve. The process of the exhaust port 8, the air return valve, and the exhaust valve adopts the principle of a venturi tube. The fused high-concentration liquid is discharged into the fish pond through the first high-oxygen outlet pipe 4 and the second high-oxygen outlet pipe 5. Finally, the jet flow at the second high-oxygen outlet pipe 5 generates thrust to mix the high-concentration water and the low-concentration water evenly during rotation, achieving the oxygenation effect of the fish pond.
