DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 8 As shown, an oxygen enrichment device includes a water supply module 100, an oxygen supply module 200, a tank body 300 and a water outlet module 400;

[0051] The water supply module 100 is used to supply water to the tank 300;

[0052] The oxygen supply module 200 is used to supply oxygen to the tank 300;

[0053] The tank 300 is used to mix water and oxygen to form oxygen-enriched water;

[0054] The water outlet module 400 is used to output oxygen-rich water to the outside, and the water outlet module 400 includes a boosting pipe 401 extending upward, and the boosting pipe 401 is used to provide a rated pressure for the tank body 300 .

[0055] In the oxygen enrichment equipment, the water supply module 100 and the oxygen supply module 200 are used to provide raw materials, namely water and oxygen, and the tank body 300 is used to mix water and oxygen to form oxygen-rich water. The oxygen-rich water is discharged from the tank body 300 through the water outlet module 400 and flows into a designated location, such as a breeding area for aquaculture.

[0056] The water outlet module 400 includes a boosting pipe 401, that is, the height of the drain outlet of the water outlet module 400 is raised by setting the boosting pipe 401. Figure 1-Figure 4 As shown, when the boosting pipe 401 is arranged vertically, the boosting pipe 401 is connected to the tank body 300 and forms a U-shaped pipe, based on which the atmospheric pressure acts on the tank body 300 through the boosting pipe 401 and forms a rated pressure. When the oxygen-enriched water in the tank body 300 flows outward, it can only flow outward after overcoming the rated pressure, thereby forming a high-pressure environment in the tank body 300, thereby increasing the solubility of oxygen and making the dissolved oxygen content greater.

[0057] At the same time, by adjusting the opening degree of the boost pipe 401 to change the rated pressure, or by adjusting the oxygen supply pressure of the oxygen supply module 200, the pressure in the tank body 300 is adjusted to achieve the purpose of controlling the dissolved oxygen content of oxygen-rich water, so as to facilitate use in different usage scenarios.

[0058] It is worth noting that when increasing the dissolved oxygen content, the oxygenation equipment uses the improvement of the mechanical structure to provide the rated pressure instead of pressurizing other equipment. At the same time, it also reduces the power requirements for the water supply module 100 and the oxygen supply module 200, greatly reducing the energy consumption of the oxygenation equipment, achieving cost reduction and efficiency improvement, and making the market prospects and market competitiveness of the oxygenation equipment better.

[0059] In a possible implementation, the dissolved oxygen content of the oxygen-enriched water is not less than 30 mg / L, and the oxygen utilization rate of the tank 300 is 90%-99.9%. In general, the dissolved oxygen content of the existing equipment is less than 30 mg / L. If it is operated at maximum power, the dissolved oxygen content of the existing equipment can be close to or reach about 30 mg / L, but at this time, the energy consumption of the existing equipment is greater, the economy is worse, and because it is operated at maximum power, the service life of the existing equipment is reduced and the failure rate is greater.

[0060] It is easy to understand that after being processed by the tank body 300, the oxygen solubility is greater, that is, when the same volume of oxygen is introduced, more oxygen is dissolved in the water body, which reduces the amount of oxygen discharged with the oxygen-enriched water, making the oxygen utilization rate higher. Therefore, the material utilization rate of the oxygen enrichment equipment is higher, the intermediate loss and waste are less, and the economy is better.

[0061] It is worth noting that, for the maximum dissolved oxygen concentration that the oxygen-enhancing device can achieve, the oxygen-enhancing device can be divided into different models according to different sizes, and the adjustment range of the dissolved oxygen concentration is not less than 30 mg / L. For the maximum dissolved oxygen concentration, the present invention does not impose any restrictions on this, and the specific adjustment range can be set according to customer requirements. For example, the dissolved oxygen concentration of one small device is 30 mg / L-100 mg / L, and can be adjusted arbitrarily within this range.

[0062] Based on this, compared with the existing technology, the oxygen enrichment equipment greatly improves the dissolved oxygen content and increases the utilization rate of oxygen; and can be flexibly adjusted according to customer needs, with a wider range of uses; in addition, it effectively reduces energy-consuming equipment and is more energy-saving and efficient.

[0063] Embodiment 2:

[0064] This embodiment describes the structure of the tank body 300 on the basis of the embodiment 1, wherein: Figure 2 and Figure 3 As shown, in a possible implementation, a water distribution module 500, a filler module 600 and a water permeable support module 700 are provided in the tank body 300;

[0065] The tank body 300 is constructed as a tank-shaped structure having a water supply port 301, an oxygen supply port 302 and a water outlet 303;

[0066] The water distribution module 500, the filling module 600 and the permeable support module 700 are sequentially arranged in the tank body 300 from top to bottom. Accordingly, the water distribution module 500 is used to evenly distribute the water on the cross section of the tank body 300, the filling module 600 is used to make the water body laminar and form oxygen-rich water, and the permeable support module 700 is used to guide the flow direction of the medium.

[0067] Based on the above design scheme, under the condition of constant pressure, if the contact area between the water body and oxygen is larger, the solubility of oxygen is greater. Based on the rated pressure provided by the boost pipe 401, the tank body 300 focuses on increasing the contact area between the water body and oxygen. To this end, in the tank body 300, the water body is evenly distributed using the water distribution module 500, and then flows downward to the filler module 600 under the action of gravity, so as to expand the contact area between the water body and the filler module 600 as much as possible, thereby increasing the utilization rate of the filler module 600. Any suitable existing filler is placed in the filler module 600. When the water body flows through the filler, the water body is in a laminar state, the specific surface area of ​​the water body increases, and the contact area between the water body and oxygen is larger, so that more oxygen can be dissolved in the water body.

[0068] Based on this, the oxygen enrichment equipment greatly increases the contact area between the water body and oxygen through the cooperation between the water distribution module 500 and the filler module 600, so that more oxygen can be dissolved in the water body, greatly improving the dissolved oxygen content of the oxygen-enriched water.

[0069] The permeable support module 700 has multiple functions. The first is the support function to ensure that the filling module 600 is stably set in the tank body 300; the second is water passing to ensure that oxygen-rich water flows into the water outlet module 400; the third is to guide the flow direction of the medium to further improve the utilization rate of oxygen.

[0070] The following is an explanation based on specific feasible implementation plans:

[0071] In a possible implementation, the water distribution module 500 includes a water distribution pipe 510 and a flow diverter 520;

[0072] The water distribution pipe 510 includes a main pipe 511 and at least one branch pipe 512. The main pipe 511 is arranged on the tank body 300 and connected to the water supply module 100. The branch pipe 512 is arranged in the tank body 300 and connected to the main pipe 511. The main pipe 511 and the branch pipe 512 are both provided with a plurality of water distribution holes 501.

[0073] The flow dividing member 520 includes a flow dividing plate 521 and a surrounding plate 522. The flow dividing plate 521 is fixedly arranged on the tank body 300 and is provided with a plurality of flow dividing holes 502. The surrounding plate 522 is constructed as an annular plate and is provided with a plurality of surrounding plates 522. With the center of the flow dividing plate 521 as the center of the circle, the plurality of surrounding plates 522 are coaxially arranged on the flow dividing plate 521. Accordingly, the flow dividing plate 521 and the surrounding plate 522 enclose a plurality of annular grooves 503.

[0074] Correspondingly, each annular groove 503 is connected to at least one water distribution hole 501 so that water flows into the annular groove 503 .

[0075] Based on the above design, the main pipe 511 is connected to the water supply module 100 to supply water to the tank 300. The more the number of branch pipes 512 is, the greater the upper limit of the water output of the water distribution pipe 510 is. Therefore, the number of branch pipes 512 can be selected according to actual needs.

[0076] It is easy to understand that when there are multiple branch pipes 512, the water inlet pipe is connected to multiple water outlet pipes 402 through the pipe joint 504. Figure 6 As shown, when there are three branch pipes 512 , the main pipe 511 is connected to the three branch pipes 512 via a four-way pipe joint.

[0077] The diverter member 520 is based on the diverter plate 521, thereby carrying other components in the water distribution module 500. The diverter plate 521 is partitioned by the enclosure 522, that is, it is divided into multiple coaxial annular grooves 503. When the water distribution pipe 510 discharges water to the annular groove 503, the water will flow along the annular groove 503 under the action of kinetic energy. When the water flows through the diverter hole 502, part of the water falls into the filling module 600, and the rest of the water continues to flow along the annular groove 503.

[0078] Thus, the water is evenly distributed in the annular groove 503 through the flow, and then falls evenly along the annular groove 503. The flow of the water can also be used to flush the diverter hole 502 to avoid clogging of the diverter hole 502. Further, the diverter plate 521 has a plurality of annular grooves 503, each of which is connected to at least one water outlet, so that each annular groove 503 is supplied with water through the water distribution pipe 510, and the water outlet of the water supply pipe is evenly distributed on the entire diverter plate 521, which not only realizes the even distribution of the water, but also flushes the entire diverter plate 521.

[0079] Optionally, the water in the annular groove 503 flows unidirectionally along the annular groove 503 to flush the diverter hole 502; accordingly, when the same annular groove 503 is connected to multiple water distribution holes 501, the multiple water distribution holes 501 are located on the same side of the pipe. Based on the above design, in order to ensure that the water is evenly distributed and flushes the annular groove 503, it is necessary to ensure that the water flows unidirectionally along the annular groove 503. Therefore, when the same annular groove 503 is connected to multiple water outlet holes, the multiple water outlet holes are located on the same side of the pipe, such as Figure 6 As shown, the water outlet is located on the left side of the pipeline so that the water flows clockwise along the annular groove 503 . Conversely, the water outlet is located on the right side of the pipeline so that the water flows counterclockwise along the annular groove 503 .

[0080] When the water flows along the annular groove 503, the water will move outward under the action of centrifugal force. If the width of the annular groove 503 is large, there will be less or no water on the side close to the center of the diverter plate 521 in the annular groove 503, and the water will gather on the side away from the center of the diverter plate 521, thereby making the distribution of the water in the annular groove 503 uneven. Therefore, preferably, the width of the annular groove 503 is 10-15 cm. Based on this, it is avoided that the width of the annular groove 503 is too large, and it is ensured that the water is evenly distributed in the annular groove 503, so that the water is evenly distributed on the diverter plate 521. For the packing module 600, the evenly distributed water flows downward evenly, increasing the utilization rate of the packing module 600 and improving the dissolved oxygen content.

[0081] During the use of the oxygenation device, especially after long-term use, dirt will inevitably be generated and cause the diverter hole 502 to be blocked. Preferably, the diverter hole 502 is constructed as a hole structure with at least a conical upper portion. Based on this, dirt accumulates from the wall surface of the hole structure to the middle portion. Since the upper portion of the diverter hole 502 has a larger volume, the probability of the diverter hole 502 being blocked is reduced. At the same time, the flow of the water body is also guaranteed, thereby achieving a certain flushing effect, which helps to slow down the progress of the diverter hole 502 being blocked.

[0082] In a possible implementation, the water-permeable support module 700 includes a water-permeable plate 701, an upper support bar 702, and a lower support plate 703;

[0083] The water-permeable plate 701 is fixed in the tank body 300 and is provided with a water-permeable hole 704 and an oxygen return hole 705;

[0084] A plurality of upper support bars 702 are provided and are spaced apart on the top surface of the water-permeable plate 701;

[0085] The lower support plate 703 is constructed as an oblique support plate evenly distributed on the bottom surface of the permeable plate 701. Accordingly, the lower support plate 703 is used to separate the space below the permeable plate 701 into two connected parts so that oxygen-enriched water flows from one part to the other along the oblique support plate.

[0086] Based on the above design scheme, the permeable plate 701 is connected to the upper and lower parts through the permeable holes 704 to ensure that the oxygen-rich water can flow through the permeable support module 700. At the same time, the upper support bar 702 and the lower support plate 703 are respectively provided on the top and bottom surfaces of the permeable plate 701, thereby improving the supporting performance of the permeable support module 700 and ensuring the stability of the oxygen enrichment equipment structure.

[0087] It is worth noting that for the oxygen enrichment equipment, when the water flows through the filler module 600, the water is in a laminar flow state, which increases the contact area between the water and oxygen, thereby increasing the efficiency and content of oxygen dissolved in the water, thereby forming oxygen-enriched water. After the oxygen-enriched water flows out of the filler module 600, the oxygen-enriched water is in a liquid state, the dissolved oxygen content of the water body decreases, and collisions may occur during the flow of the oxygen-enriched water, such as collisions with the permeable support module 700, etc., which will cause the oxygen dissolved in the water to be released, reducing the dissolved oxygen content of the oxygen-enriched water.

[0088] Based on this, by tilting the lower support plate 703, on the one hand, the flow rate of the oxygen-rich water can be slowed down, the collision intensity can be reduced, the release of oxygen can be reduced, and the dissolved oxygen content of the oxygen-rich water can be ensured; on the other hand, the distance that the oxygen-rich water flows to the water outlet module 400 can be extended, and the released oxygen can flow back to the filling module 600 through the oxygen reflux hole 705, thereby realizing the reuse of oxygen and achieving the effect of improving the oxygen utilization rate.

[0089] Optionally, the upper end of the inclined support plate is inclined toward the center of the water-permeable plate 701 and connected to the water-permeable plate 701, the lower end of the inclined support plate is inclined toward the inner wall of the tank body 300 and abuts against the tank body 300, and a water-passing gap is left between the lower end of the inclined support plate and the inner wall of the tank body 300;

[0090] Correspondingly, the lower part of the water-permeable plate 701 is divided by the diagonal support plate into a water outlet area 706 located inside the diagonal support plate and a water permeable area 707 located outside the diagonal support plate; the multiple water-permeable holes 704 are divided into at least two water-permeable groups, and the water-permeable groups are all located in the water-permeable area 707, so that oxygen-enriched water flows from the water-permeable area 707 into the water outlet area 706; a plurality of oxygen reflux holes 705 are provided and are all located in the water outlet area 706, so that the oxygen separated from the oxygen-enriched water can flow back to the filling module 600 through the oxygen reflux holes 705.

[0091] Based on the above design, the oxygen-enriched water enters the water-permeable area 707 through the water-permeable hole 704. At this time, the oxygen-enriched water also contains a certain amount of released oxygen. The oxygen-enriched water and oxygen flow along the lower support plate 703 until they flow into the water outlet area 706. Since the density of oxygen is lower than that of oxygen-enriched water, at this time, the oxygen will flow upward relative to the oxygen-enriched water. Since the overall flow rate is low and the flow distance is long, the oxygen has enough time to flow upward and flow back to the packing module 600 through the oxygen return hole 705.

[0092] Based on this, most of the oxygen in the tank 300 is dissolved into the water at the filler module 600, so that the minimum utilization rate of oxygen in the oxygen enrichment device reaches 90%. After the oxygen-enriched water flows into the water outlet 706, among the released oxygen, except for a very small part of the oxygen that is discharged with the oxygen-enriched water, the rest of the oxygen will flow back to the filler module 600 for reuse, so that the oxygen utilization rate of the oxygen enrichment device is close to 99.9%.

[0093] For oxygen-enriched water, part of the oxygen-enriched water flows out of the tank body 300 through the water outlet module 400, and the rest of the oxygen-enriched water is temporarily stored in the lower part of the tank body 300. Accordingly, a water level gauge 801 is provided outside the tank body 300, and the water level gauge 801 displays the liquid level of the oxygen-enriched water.

[0094] It is easy to understand that when the liquid level of the oxygen-enriched water is low, oxygen will exist between the oxygen-enriched water and the water-permeable plate 701, and this part of oxygen will be easily discharged with the oxygen-enriched water. In this case, the oxygen utilization rate of the oxygen enrichment equipment is also reduced.

[0095] In one possible implementation, the water outlet module 400 includes a water outlet pipe 402, which is arranged in the tank body 300 and connected to the boosting pipe 401, and the water outlet pipe 402 is located below the permeable plate 701 and in the water outlet area 706, and the water inlet of the water outlet pipe 402 is arranged on the bottom surface of the water outlet pipe 402.

[0096] Based on the above design, since oxygen has a low density and flows upward, the water inlet of the water outlet pipe 402 is set on the bottom surface of the water outlet pipe 402, so as to minimize the amount of oxygen flowing into the water outlet pipe 402, so that the released oxygen can flow back to the filling module 600 as much as possible to improve the utilization rate of oxygen.

[0097] like Figure 2 and Figure 3 As shown, the water outlet pipe 402 is preferably disposed in the middle of the water outlet area 706 so that oxygen-enriched water from all directions flows into the water outlet pipe 402 evenly.

[0098] In a possible implementation, the lower end of the boost pipe 401 extends to the lower part of the tank body 300 and is connected to the water outlet pipe 402, and the upper end of the boost pipe 401 extends upward and is provided with a drain outlet, and a control valve for adjusting the rated pressure is provided on the drain outlet.

[0099] Based on the above design, the control valve is used to control the opening of the drain port. When the control valve is adjusted to reduce the opening of the drain port, the water flow rate of the boosting pipe 401 is reduced, but the rated pressure generated by the boosting pipe 401 is increased, which helps to increase the dissolved oxygen content of the oxygen-enriched water in the tank body 300. Conversely, when the control valve is adjusted to increase the opening of the drain port, the water flow rate of the boosting pipe 401 is increased, but the rated pressure generated by the boosting pipe 401 is reduced, which reduces the dissolved oxygen content of the oxygen-enriched water in the tank body 300.

[0100] At this time, due to the change in the water outlet flow rate of the boosting pipe 401, the water level of the oxygen-rich water in the tank body 300 will also change. Accordingly, the water supply of the water supply module 100 should be adjusted at this time to avoid the liquid level of the oxygen-rich water being lower than the water inlet of the water outlet pipe 402, thereby preventing a large amount of oxygen from directly entering the water outlet pipe 402 and flowing out of the tank body 300, thereby ensuring the utilization rate of oxygen.

[0101] It is worth noting that, in addition to adjusting the opening of the drain port by the control valve, the pressure in the tank 300 can also be adjusted by adjusting the oxygen supply pressure of the oxygen supply module 200, thereby controlling the dissolved oxygen content of the oxygen-enriched water. It is easy to understand that when the dissolved oxygen content of the oxygen-enriched water needs to be adjusted, at least one of the control valve and the oxygen supply module 200 can be adjusted.

[0102] In a possible implementation, an exhaust port 304 and the oxygen supply port 302 are provided on the top surface of the tank body 300, and the oxygen outlet end of the oxygen supply module 200 is connected to the tank body 300 through the oxygen supply port 302; a sewage outlet 305 is provided on the bottom surface of the tank body 300, and a sewage pipe is provided on the sewage outlet 305, and the water inlet of the sewage pipe is set on the bottom surface of the sewage pipe.

[0103] Based on the above design, before the oxygen enrichment device is used for the first time, there is air in the tank body 300. If this part of the air is not removed, the oxygen-enriched water will have a low dissolved oxygen content. However, as the air is exhausted, the lowest dissolved oxygen content of the oxygen-enriched water is restored to 30 mg / L, but this process takes a long time. Therefore, an exhaust port 304 is provided on the tank body 300. When the oxygen enrichment device is used for the first time, the exhaust port 304 is opened, and the water supply module 100 supplies water until the exhaust port 304 overflows, which means that the air in the tank body 300 is exhausted, and the exhaust port 304 can be kept closed afterwards.

[0104] The connection between the oxygen outlet of the oxygen supply module 200 and the tank body 300 is on the top surface of the tank body 300. On the one hand, it prolongs the flow distance of oxygen, increases the contact time between oxygen and water, and helps to increase the dissolved oxygen content. On the other hand, it also allows oxygen to flow through the diverter plate 521, thereby using oxygen to flush the diverter hole 502, and cooperates with the flushing of the water body, further reducing the possibility of blockage of the diverter plate 521.

[0105] It is easy to understand that after long-term use, dirt will still appear in the tank body 300, so the oxygenation equipment needs to be cleaned. At this time, detergent, flushing water, etc. are injected through the exhaust port 304 located on the top surface of the tank body 300 for cleaning, and the sewage is discharged through the sewage outlet 305. And the water inlet of the sewage pipe is preferably set on the bottom surface of the sewage pipe to ensure that the sewage is completely discharged. After cleaning, the performance of the oxygenation equipment is restored. Note that when the oxygenation equipment is used again, water should be supplied through the water supply pipe to discharge the air in the tank body 300.

[0106] Here, the working principle of the oxygen enrichment device is explained in combination with the structure of the oxygen enrichment device to explain how the oxygen enrichment device adjusts the dissolved oxygen and the oxygen utilization rate. Specifically:

[0107] The exhaust port 304 is opened, and the water supply module 100 is started to supply water into the tank body 300. After the exhaust port 304 overflows with water, the exhaust port 304 is closed.

[0108] Start the oxygen supply module 200 to supply oxygen into the tank body 300, observe the liquid level of the oxygen-enriched water through the water level gauge 801 outside the tank body 300, and adjust at least one of the control valve and the oxygen supply module 200 until the discharged oxygen-enriched water meets the use requirements.

[0109] When it is necessary to adjust the dissolved oxygen content of the oxygen-enriched water, taking increasing the dissolved oxygen content as an example, the control valve is adjusted to reduce the opening of the drain port, the rated pressure increases, and in the packing module 600, more oxygen is dissolved into the water body due to the increase in the rated pressure, thereby increasing the dissolved oxygen content of the oxygen-enriched water. The liquid level of the oxygen-enriched water in the tank body 300 decreases due to the increase in pressure, and oxygen is more easily discharged with the oxygen-enriched water, and the oxygen utilization rate decreases. In the boosting pipe 401, due to the decrease in the opening of the drain port, the water output of the boosting pipe 401 is also reduced.

[0110] Embodiment 3:

[0111] This embodiment describes the remaining structures of the oxygenation equipment based on Embodiments 1 and 2. Specifically:

[0112] In a possible implementation, a water level gauge 801 is disposed outside the tank body 300 , the water level gauge 801 is fixed at the lower portion of the tank body 300 , and the permeable support module 700 is located between the upper and lower ends of the water level gauge 801 .

[0113] Based on the above design, the water level meter 801 is used to display the liquid level of the oxygen-rich water in the tank 300, so that the staff can timely grasp the water level of the tank 300. If the water level is abnormal, the control module 900 is used to promptly notify the staff to handle it to avoid unexpected situations.

[0114] In one possible implementation, a reinforcement structure is provided on the tank body 300, and the reinforcement structure includes an upper reinforcement frame, a lower reinforcement frame, a pull rod 801 and a reinforcement belt 802; the upper reinforcement frame is fixed on the top plate of the tank body 300, and the lower reinforcement frame is fixed on the bottom plate of the tank body 300; a plurality of reinforcement belts 802 are provided and are fixed on the outer periphery of the tank body 300 at intervals from top to bottom; a plurality of pull rods 801 are provided, and the upper and lower ends of each pull rod 801 are respectively connected to the top plate and the bottom plate of the tank body 300 through a pull seat.

[0115] Based on the above design scheme, the reinforcement structure increases the structural strength of the top of the tank body 300 through the upper reinforcement frame, increases the structural strength of the bottom of the tank body 300 through the lower reinforcement frame, and connects the upper reinforcement frame and the lower reinforcement frame through the pull rod 801 to improve the integrity of the reinforcement structure, effectively increase the overall structural strength of the tank body 300, protect the tank body 300, and ensure that the tank body 300 reaches the designed service life.

[0116] The reinforcement strips 802 are used to strengthen the tank body 300. Especially when the tank body 300 is large in volume, the oxygen enrichment equipment has a large deadweight. By flexibly selecting the number and layout of the reinforcement strips 802, the service life of the tank body 300 is ensured to meet the design requirements.

[0117] Different types of oxygenation equipment, especially large-sized oxygenation equipment, are subjected to high pressure. In order to ensure the safety of operation, it is necessary to increase the structural strength of the oxygenation equipment by reinforcing the structure.

[0118] In a possible implementation, (the oxygen enrichment device) further includes a control module 900, which includes a chassis 901, an indicator light 902, a switch 903, a current display 904, a dissolved oxygen display 905, and an oxygen flow meter 906. The chassis 901 is equipped with a processor, and the indicator light 902, the switch 903, the current display 904, the dissolved oxygen display 905, and the oxygen flow meter 906 are all installed on the chassis 901 and electrically connected to the processor;

[0119] Correspondingly, the water supply module 100, the oxygen supply module 200 and the water outlet module 400 are respectively electrically connected or communicatively connected to the processor.

[0120] Based on the above design scheme, the control module 900 is started and stopped through the switch 903, and the indicator light 902, the current display 904, the dissolved oxygen display 905 and the oxygen flow meter 906 respectively display corresponding information to facilitate the staff to grasp the operating status and real-time data of the oxygen enrichment equipment, and then adjust it according to the changes in actual usage needs.

[0121] Furthermore, for the connection form between the control module 900 and the tank body 300, there are multiple solutions based on the convenience of operation and viewing by the staff, according to the specific situation. Specifically, in the integrated design, if the volume of the tank body 300 is small, the chassis 901 is fixed on the top surface of the tank body 300; if the volume of the tank body 300 is large, the chassis 901 is fixed on the side of the tank body 300. In the split design, if the tank body 300 needs to be put into water, the chassis 901 is separated from the tank body 300 and electrically connected through wires, and the chassis 901 can be placed in any suitable position.

[0122] For each functional module in the tank 300, optionally, Figure 2As shown, a vertical shaft 306 is provided in the tank body 300, and the top plate and the bottom plate of the tank body 300 are connected by the shaft 306, and the water distribution module 500 and the water permeable support module 700 are also connected to the shaft 306. Based on this, the functional modules in the tank body 300 are further supported and fixed by the shaft 306 to ensure the structural strength and stability of the oxygen enrichment device.

[0123] Or, if Figure 3 As shown, in the water distribution module 500, at least one upper rod 307 is provided on the diverter plate 521, and in the water permeable support module 700, at least two lower support rods 308 are provided below the water permeable plate 701. Based on this, the upper rod 307 plays a connecting role and ensures that the diverter plate 521 will not deform. Similarly, the lower support rod 308 plays a connecting role and ensures that the water permeable plate 701 will not deform.

[0124] Embodiment 4:

[0125] Based on Examples 1-3, this embodiment takes aquaculture as an example to illustrate the technical effects that can be achieved by the oxygenation equipment:

[0126] Except for the control module 900, the other components use mechanical structures to adjust the dissolved oxygen content and oxygen utilization rate. Compared with existing air-type oxygen enrichment equipment and dissolved oxygen cones, the number of power-consuming equipment is greatly reduced, so that the energy consumption of the oxygen enrichment equipment is greatly reduced. Compared with ceramic plates, the oxygen enrichment equipment not only has a high oxygen utilization rate, does not have a plate explosion phenomenon, but also has better stability and safety.

[0127] The control valve on the booster pipe 401 cooperates with the oxygen supply module 200 to adjust the oxygen flow and achieve precise oxygen supply: the oxygen supply can be flexibly adjusted according to the breeding density and the actual demand for dissolved oxygen in the water body to ensure that the dissolved oxygen level in the water is always within an appropriate range, meet the physiological needs of aquatic animals, and avoid death or growth stunting caused by lack of oxygen.

[0128] Improving the ecological environment of water microorganisms and improving water quality can increase the conversion rate of feed coefficient, which not only reduces feed input, but also advances the time for aquaculture to be put on the market, increasing economic value for farmers.

[0129] It is easy to understand that the oxygen enrichment equipment can be used in aquaculture, and can also be used in any other suitable usage scenarios, and the present invention does not impose any limitation on this.

[0130] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
