Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, and particularly relates to an oxygen dissolving machine for improving the dissolved oxygen efficiency in aquaculture. Background Art

[0002] In the field of aquaculture, dissolved oxygen machines, as key equipment for increasing the dissolved oxygen content in water, play a vital role in ensuring the normal growth and development of aquatic organisms. With the continuous advancement of aquaculture technology, the design of dissolved oxygen machines has also evolved from simple to complex, from inefficient to efficient. Traditional dissolved oxygen machines mainly introduce oxygen into water bodies through mechanical stirring or bubble release. Although it can increase the dissolved oxygen content in water bodies to a certain extent, the dissolution efficiency is relatively low, and there are problems such as high energy consumption, high noise, and high maintenance costs.

[0003] However, traditional dissolved oxygen machines mainly increase the dissolved oxygen content by directly injecting oxygen or air into the water. Although these devices meet the basic needs of aquaculture to a certain extent, their dissolved oxygen efficiency is generally not high, resulting in high energy consumption and low oxygen utilization rate. Specifically, traditional dissolved oxygen machines often use simple bubble generating devices to inject oxygen or air into the water in the form of larger bubbles. In this way, the bubbles rise quickly and have a short contact time with the water, which makes it impossible for oxygen to be fully dissolved in the water. A large amount of oxygen is not utilized when it escapes from the water surface, resulting in waste. In addition, traditional dissolved oxygen machines often lack an effective oxygen recovery mechanism during operation, and unfused oxygen is directly discharged into the environment, further reducing the oxygen utilization rate, so staff need to improve them.

A second micro-nano gas waterfall nozzle 16 is installed at the output end of the water supply pump 15, and the bottom end of the second connecting pipe 13 is fixedly connected to the top of the second micro-nano gas waterfall nozzle 16. The surface of the oxygen dissolving machine body 1 is located on one side of the first micro-nano gas waterfall nozzle 2 and is fixedly connected to a distribution box 17, and the distribution box 17 and the water supply pump 15 are electrically connected to each other. A plurality of isolation frames 18 are fixedly connected to the inner wall of the oxygen dissolving machine body 1, and a baffle 19 is overlapped on the top of the isolation frame 18, and a partition 20 is fixedly connected to the surface of one of the isolation frames 18.

[0035] When in use, a plurality of control valves 11 are provided on the surface of the oxygen filling pipe 10 for adjusting the supply of oxygen. The bottom of the oxygen filling pipe 10 is connected to the oxygen inlet pipe 5 through the first connecting pipe 12 to provide oxygen for the first micro-nano gas waterfall nozzle 2. The bottom of the second connecting pipe 13 penetrates and is plugged into the inner wall of the oxygen dissolving machine body 1, and is connected to the output end of the water supply pump 15. The water supply pump 15 is used to transport water to the inside of the oxygen dissolving machine body 1 for oxygen dissolving treatment. The surface of the oxygen recovery pipe 6 is sleeved with a third connecting pipe 14. The front end of the third connecting pipe 14 penetrates and is plugged into the inner wall of the oxygen dissolving machine body 1. The inner wall of the oxygen dissolving machine body 1 is used to recycle the incompletely dissolved oxygen into the oxygen dissolving machine body 1 for reuse.

Using the principle that bubbles always float upward in the water body due to water pressure, the water depth in the machine is more than 1.2 meters, and the outlet pipe is submerged 1.13 meters underwater. In order to prevent a large number of bubbles above the nanometer level from moving rapidly under the action of the machine when the machine is working, To avoid waste caused by being carried away with the outlet pipe, a 1.2-meter-high partition 20 is set 50 centimeters away from the outlet. The water level in the machine must be more than 1.2 meters to evenly flow to the isolation chamber composed of the isolation frame 18 and the partition 20, rather than being shot down by pressure at a certain point. The volume of the isolation chamber is 0.9 cubic meters, and the water level in the isolation chamber is always maintained at a depth of 1.2 meters. Even if oxygen bubbles flow into the isolation chamber, the bubbles always float upward, and there will be no oxygen bubbles in the water body more than one meter deep, which avoids the phenomenon of oxygen loss with water.

[0036] Embodiment three:

[0037] See also Figures 1 to 6 As shown in the figure, in large-scale aquaculture bases, due to the high breeding density, the dissolved oxygen in the water body often cannot meet the growth needs of fish. Although the traditional dissolved oxygen machine can provide a certain amount of oxygen, the dissolution efficiency is not high, which leads to increased breeding costs and limited fish growth rate. In order to improve the breeding efficiency, this dissolved oxygen machine is used for testing.

[0038] The dissolved oxygen machine is mainly composed of the dissolved oxygen machine body, the first micro-nano air waterfall nozzle, the oxygen recovery pipe, the thickening layer, the annular oxygenation tank and the oxygen exhaust tank. In actual application, the dissolved oxygen machine is installed at an appropriate position in the aquaculture pond, and oxygen is filled into the annular oxygenation tank through the oxygen inlet pipe, and the oxygen is quickly discharged through the oxygen exhaust tank, so that it merges with the water body at a high speed, thereby improving the fusion rate of oxygen and water.

[0039] In particular, the design of recycling oxygen pipe to absorb unfused oxygen and discharge it back into the oxygen dissolving machine body, and then reuse it through the oxygen recovery system, significantly improves the utilization rate of oxygen and reduces waste. At the same time, the design of the first micro-nano gas waterfall nozzle enables oxygen to be dispersed in the water in the form of micro-nano bubbles, further improving the dissolution efficiency.

[0040] Application Effect

[0041] After a period of trial operation, the dissolved oxygen machine showed significant application effects. First, the dissolved oxygen content in the breeding pond has been significantly improved, meeting the growth needs of fish. Secondly, due to the high oxygen utilization rate, the breeding cost has been effectively reduced. Finally, the growth rate of fish has been significantly accelerated, and the breeding benefits have been significantly improved.

[0042] Specifically, compared with traditional dissolved oxygen machines, this dissolved oxygen machine increases the dissolved oxygen content in the breeding pond by about 30%, and the oxygen utilization rate also increases by about 20%. This not only improves the growth rate and quality of fish, but also reduces the incidence of diseases during the breeding process and reduces breeding risks.

[0043] In addition, the dissolved oxygen machine is easy to operate and maintain. The staff only needs to check and clean the equipment regularly to ensure its normal operation. At the same time, the equipment also has intelligent control functions, which can automatically adjust the oxygen supply according to the breeding needs, further improving the breeding efficiency.

[0044] Working principle: When in use, the width of the oxygen discharge groove 9 is one millimeter, and oxygen is filled into the annular oxygen filling groove 8 by using the oxygen inlet pipe 5. The oxygen in the arc-shaped oxygen filling groove 8 is quickly discharged through the oxygen discharge groove 9, so that the oxygen and water are fused at a high speed, and the unfused oxygen is directly absorbed and discharged into the interior of the oxygen dissolving machine body 1 through the oxygen recovery pipes 6 on both sides, and then the oxygen inside the oxygen dissolving machine body 1 is recovered through the oxygen recovery system, and then the oxygen is discharged into the interior of the first micro-nano gas waterfall nozzle 2 through the oxygen inlet pipe 8 through the discharge system, which can make the oxygen that has not become micro-nano level recovered into the circulation system, and repeatedly circulated and sprayed through the first micro-nano gas waterfall nozzle 2, and finally the oxygen is 100% dissolved in the water body before it can flow out of the water outlet, because the high-oxygen water does not flow out of the water outlet directly, but the water outlet is provided with elbows and pipes of the same size, and the water inlet of the pipe is away from the machine. The bottom is only 7 centimeters. Using the principle that bubbles always float upward due to water pressure, the water depth in the machine is more than 1.2 meters, and the outlet pipe is submerged 1.13 meters underwater. In order to prevent a large number of bubbles above the nanometer level from moving rapidly under the action of the machinery when the machine is working, and being carried away with the outlet pipe to cause waste, a 1.2-meter-high partition 20 is set 50 centimeters away from the outlet. The water level in the machine must be more than 1.2 meters to flow evenly to the isolation chamber composed of the isolation frame 18 and the partition 20, rather than being shot down by pressure at a certain point. The volume of the isolation chamber is 0.9 cubic meters, and the water level in the isolation chamber is always maintained at a depth of 1.2 meters. Even if oxygen bubbles flow into the isolation chamber, the bubbles always float upward, and there will be no oxygen bubbles in the water more than one meter deep, which avoids the phenomenon of oxygen loss with water.

[0045] The high-pressure head is 40 meters, the water pump motor is 7.5 kilowatts, the flow rate is 40 cubic meters, the dissolved oxygen content is 28 mg per liter of water, the average power consumption per cubic meter of flow is 187.5 watts / hour, and the average oxygen consumption is 1.25 liters per cubic meter.

[0046] The head is 24 meters, the water pump motor is 5.5 kilowatts, the flow rate is 50 cubic meters, the dissolved oxygen content is 24 mg per liter of water, the average power consumption per cubic meter of flow is 110 watts / hour, and the average oxygen consumption per cubic meter is 0.8 liters.

[0047] The head is 16 meters, the water pump motor is 5.5 kilowatts, the flow rate is 210 cubic meters, the dissolved oxygen content is 21.5 mg per liter of water, the average power consumption per cubic meter of flow is 26.2 watts / hour, and the average oxygen consumption per cubic meter is 0.285 liters.

[0048] The head is 14 meters, the water pump motor is 11 kilowatts, the flow rate is 360 cubic meters, the dissolved oxygen content is 19 mg per liter of water, the average power consumption per cubic meter of flow is 30.5 watts / hour, and the average oxygen consumption per cubic meter is 0.30 liters.

[0049] The results of various pressure tests show that the medium pressure head of 16 to 18 meters and the large flow rate of 210 to 400 cubic meters have the highest dissolved oxygen efficiency and the lowest energy consumption, and are most suitable for a wide range of applications.
