Description

Technical Field

[0001] The invention relates to the technical field of aquatic product breeding, and in particular to a feeding and oxygenation device and an oxygenation method for a white shrimp breeding pond. Background Art

[0002] In the aquaculture industry, especially in the breeding process of whiteleg shrimp, whiteleg shrimp, as a high-economic-value aquatic product, is extremely sensitive to water quality conditions, especially dissolved oxygen content. Adequate dissolved oxygen is not only directly related to the growth rate, health status and survival rate of shrimp, but also affects the overall ecological balance of the breeding pond.

[0003] A novel aquatic product feeding and oxygenation breeding device with Chinese patent publication number CN221178925U includes a floating platform, a mixing tank, a solenoid valve and a driving mechanism; the upper surface of the floating platform is connected to the mixing tank, the bottom of the mixing tank is connected to the solenoid valve, and the back of the floating platform is provided with a driving mechanism. By putting the device into water, starting the cylinder to shorten, pulling the transmission rod, driving the support rod to rotate, putting the blade into the water, and then starting the driving motor to drive the blade to rotate, pushing the device to move, and then moving, by starting the servo motor to drive the air cylinder to rotate in the cover shell, releasing the hose, and the gravity of the counterweight block sinks the air outlet plate into the water. After reaching the appropriate depth, the servo motor is turned off and the air pump is started to send the outside air from the hard pipe into the cover shell, and then into the air cylinder, and then sent from the hose to the air outlet plate for spraying, thereby adjusting the oxygenation depth. This patent mainly involves injecting air into water to bring it into contact with water for oxygenation. This method has a short contact time between the injected air and water, and the air immediately floats out of the water after being ejected, so the oxygenation effect on the water is poor. The amount of oxygen that can be dissolved is limited, and the oxygenation effect on the water body is not obvious. Summary of the invention

[0004] One of the purposes of the present invention is to provide a feeding and oxygenation device for a white shrimp aquaculture pond, so as to solve the problem that the air filled into the aquaculture pond in the past has a short contact time with water, and the filled air immediately floats out of the water after being sprayed out, resulting in poor pond oxygenation effect; the second purpose is to provide an oxygenation method.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A feeding and oxygenation device for a white shrimp breeding pond, comprising a carrier, a feeding mechanism and a mixing mechanism, wherein the feeding mechanism and the mixing mechanism are both arranged on the carrier; The mixing mechanism comprises an air supply member, a flow divider seat and a mixing unit, wherein the flow divider seat is connected to the air supply member and the mixing unit respectively, and the air supply member supplies air to the mixing unit through the flow divider seat; The diverter seat is provided with a first air outlet; The mixing unit comprises a water inlet disc, a mixing element, a turbofan, a water disturbance unit and a water inlet shaft, wherein the water inlet disc is fixed on the top of the mixing element, a mixing chamber is provided in the mixing element, the water inlet shaft is arranged in the mixing chamber and is coaxially rotatably connected with the water inlet disc, and the turbofan and the water disturbance unit are coaxially mounted on the water inlet shaft; wherein the water inlet shaft can drive the turbofan and the water disturbance unit to rotate around the axis of the water inlet shaft under the drive of the air supply element; The circumferential surface of the water inlet pan is provided with a plurality of water inlets, the water inlet shaft is provided with a plurality of water outlets, the water inlets and the water outlets are communicated with each other, the water inlet pan is fixed to the bottom of the diverter seat and is communicated with the first air outlet.

[0006] According to the above technical scheme, the air supply component is used as a gas power source to supply air, and the gas is passed into the diverter seat, and then the diverter seat introduces the gas into the mixing component. When the gas enters the mixing component, it can drive the turbofan to rotate, and then drive the water inlet shaft to rotate through the turbofan, and when the water inlet shaft rotates, it drives the water disturbance unit to rotate; at the same time, the water flow of the breeding pond enters the water inlet shaft through the water inlet on the water inlet plate, and the water flow is discharged through the water outlet on the water inlet shaft, and then enters the mixing chamber. The water disturbance unit rotates to mix the water flow and air in the mixing chamber. Through the synergistic effect of the turbofan and the water disturbance unit, the water and air are fully mixed, and the oxygen filled in the air flow gradually dissolves in the water to form an oxygen-rich water body, thereby achieving the purpose of oxygen increase.

[0007] Furthermore, the water inlet tray comprises a water inlet ring and at least one water inlet column, each of the water inlet columns is arranged inside the water inlet ring, and each of the water inlet columns is provided with a first flow channel connected to each of the water inlets; A second flow channel is arranged in the water inlet shaft, the first flow channel is connected to the second flow channel, and the second flow channel is connected to the water outlet.

[0008] According to the above technical solution, the water inlet ring is located on the periphery, and the water inlet column is arranged inside the water inlet ring to form one or more independent water inlet channels. A first flow channel is arranged in each water inlet column, and these first flow channels are connected with the water inlet on the peripheral surface of the water inlet disk to guide the water in the pond to flow in. A second flow channel is arranged in the water inlet shaft, and the second flow channel is connected with the first flow channels in multiple water inlet columns to form a continuous water flow channel. At the same time, the second flow channel is also connected with the water outlet on the water inlet shaft to guide the water in the pond into the mixing chamber for subsequent mixing and oxygenation.

[0009] Furthermore, the water disturbance unit comprises a first spoiler fan and a second spoiler fan, and the first spoiler fan and the second spoiler fan are both coaxially arranged on the water inlet shaft; A plurality of first arc-shaped blades are formed on the first spoiler fan, and each of the first arc-shaped blades is twisted and fixed on the first spoiler fan along a first direction; A plurality of second arc-shaped blades are formed on the second spoiler fan, and each of the second arc-shaped blades is twisted and fixed on the second spoiler fan along a second direction; The first direction is opposite to the second direction.

[0010] According to the above technical solution, when the water inlet shaft rotates, the first spoiler fan and the second spoiler fan are also driven to rotate. The torsion direction of the first arc-shaped blade is opposite to the torsion direction of the second arc-shaped blade. The design of the blades in opposite directions can produce different fluid dynamic effects; when the first spoiler fan stirs the airflow and water flow, the first arc-shaped blade will stir the fluid in one direction to dissolve oxygen; then, when the second spoiler fan stirs the airflow and water flow, the second arc-shaped blade stirs the fluid in the opposite direction. This reverse stirring can further enhance the turbulence and shear force inside the fluid, thereby forming a complex flow field in the water body, which is conducive to the full mixing between gas and liquid. This flow field helps to promote the overall circulation and flow of the water body, increase the dissolved oxygen content in the water body, and provide a sufficient oxygen environment for aquatic organisms such as white shrimp.

[0011] Furthermore, the water disturbance unit further comprises a stirring frame head, and the stirring frame head is coaxially fixed on the water inlet shaft; The stirring frame head comprises an inner frame and an outer frame which are coaxially arranged, and a plurality of holes are arranged on the inner frame and the outer frame.

[0012] According to the above technical scheme, the water flow in the pond first flows out through the water outlet on the water inlet shaft and is guided to the mixing chamber. When the water flow enters the mixing chamber, the water flow first contacts the inner frame of the mixing frame head. The inner frame is provided with a plurality of holes. During the rotation of the inner frame, these holes allow the water flow to pass through and preliminarily divert and refine the water flow. The water flow forms a smaller water flow beam inside the inner frame and flows out through the holes and enters the outer frame area. The water flow out of the inner frame then enters the outer frame. The outer frame is also provided with a plurality of holes. These holes further disperse and mix the water flow. Since the water flow has been preliminarily refined in the inner frame, a more uniform and fine water flow distribution can be formed in the outer frame. The mixing frame head is coaxially fixed on the water inlet shaft and rotates with the rotation of the water inlet shaft. During the rotation, the mixing frame head will drive the surrounding airflow and water flow to rotate together, generating centrifugal force. The centrifugal force generated by the rotation will cause the water flow and airflow to flow from the center of the mixing chamber to the outside of the mixing chamber. The oxygen-rich water will finally flow out through the bottom of the mixing element into the breeding pond. At the same time, the centrifugal force can also promote the breakage and dispersion of bubbles in the mixing chamber, so that oxygen can be more evenly dissolved in the water.

[0013] Furthermore, the feeding mechanism includes a feeding box, a conveying pipe, a first motor and a conveying roller. The conveying pipe is arranged at the bottom of the feeding box for conveying feed, and the conveying roller is coaxially arranged in the conveying pipe. The first motor is coaxially connected to the end of the conveying roller for driving the conveying roller to rotate. A feeding port is arranged on the side of the conveying pipe away from the first motor.

[0014] According to the above technical solution, after the first motor is started, the conveying roller is driven to rotate in the conveying pipe through a coaxial connection. The rotation of the conveying roller provides power for the conveying of the feed. The feed is put into the feeding box. As the conveying roller rotates, the feed is gradually pushed into the conveying pipe. The conveying roller in the conveying pipe continues to push the feed forward until the feed is discharged from the feeding port, thereby achieving the purpose of feeding the white shrimp.

[0015] Furthermore, it also includes a blowing unit, which is arranged at the bottom of the feeding port and is used to blow the feed in the feeding port; The blowing unit comprises an air distribution plate and a first air pipe, wherein an air cavity and a plurality of air outlets are provided in the air distribution plate, and each of the air outlets is connected to the air cavity; an air inlet and a second air outlet are provided on the diverter seat, and both the first air outlet and the second air outlet are connected to the air inlet; One end of the first air tube is in communication with the air cavity, and the other end of the first air tube is in communication with the second air outlet; The first air pipe is provided with a switch, and the switch can be turned on or off.

[0016] According to the above technical solution, the gas enters the air cavity of the air distribution plate through the first air pipe. When the feed is discharged from the feeding port, the blowing unit at the bottom of the air distribution plate starts to work, and the gas ejected from the air outlet blows the feed, so that the feed is more evenly distributed in the pond under the drive of the air flow, so that the feed is more evenly distributed in the pond, reducing the growth differences caused by competition for food, helping to reduce the accumulation and waste of feed in the pond, and blowing can also promote the softening and dissolution of the feed, and improve the absorption rate of the feed by aquatic organisms; the switch set on the first air pipe is used to control the flow and switch of the gas. By adjusting the degree of opening of the switch, the strength and range of blowing the feed can be controlled to adapt to different breeding needs and environmental conditions.

[0017] Furthermore, a one-way valve is provided in the first flow channel and / or the second flow channel, and the one-way valve is used for one-way conduction from the water inlet to the mixing chamber.

[0018] According to the above technical solution, the one-way valve can ensure that water can only flow in the set direction (i.e., from the water inlet to the mixing chamber), effectively preventing water from flowing back during the mixing process or when the pressure changes.

[0019] Furthermore, the air supply component includes an air supply shell, fan blades arranged in the air supply shell and a second motor for driving the fan blades to rotate. The top of the air supply shell is provided with an air inlet, and the bottom of the air supply shell is provided with an air outlet. The fan blades can drive the airflow of the air inlet into the air outlet, and the air outlet is connected to the air inlet duct of the diverter seat.

[0020] According to the above technical solution, the second motor is installed outside the air supply shell to drive the fan blades to rotate. The rotation of the fan blades generates airflow. The airflow enters from the air inlet and is discharged from the air outlet. The air inlet of the diverter seat is connected to the air outlet of the air supply member. The diverter seat is used to receive the airflow from the air supply member and distribute it to the mixing chamber.

[0021] Furthermore, it also includes an oxygenation box fixedly arranged on the diverter seat, the top of the oxygenation box is open, a first steel frame net and a second steel frame net parallel to each other are arranged in the oxygenation box, a plurality of bubble flotation elements are arranged between the first steel frame net and the second steel frame net, and the density of the bubble flotation element is greater than the density of water; The bubble flotation element is constructed with a plurality of membrane holes around it for adhering bubbles; after the bubble flotation element is saturated with bubbles, the buoyancy of the bubbles can drive the bubble flotation element to float upward; The first steel frame net is arranged above the second steel frame net; A transmission rod is connected to the first steel frame, and the other end of the transmission rod is connected to the second motor.

[0022] According to the above technical solution, the bubble flotation element is placed between the first steel frame net and the second steel frame net, and a number of membrane holes are constructed around it for adhering bubbles. When the oxygen-enriched water carries bubbles into the bottom of the oxygenation box, some bubbles will adhere to the membrane holes of the bubble flotation element. As the number of bubbles adhering to the bubble flotation element increases, the buoyancy of the bubbles gradually increases. When the buoyancy exceeds the gravity of the bubble flotation element itself, the bubble flotation element begins to float up. The vibration generated by the second motor when working is transmitted to the first steel frame net through the transmission rod, causing it to vibrate. When the floating bubble flotation element contacts the vibrating first steel frame net, the bubbles fall off from the membrane holes of the bubble flotation element. After the bubbles fall off, the bubble flotation element begins to sink due to the loss of buoyancy, returns to the initial position, and is ready to adhere to bubbles again. The above process is repeated, and the oxygen in the bubbles is continuously released into the water body during the process of adhering, floating, debubbling and sinking, which prolongs the immersion time of the bubbles in the water and increases the dissolved oxygen content of the water body.

[0023] Furthermore, a tail column connected to the mixing chamber is provided at the bottom of the mixing element, and the cross-section of the tail column gradually decreases along the length direction of the mixing element; a second air pipe is connected to the tail column, and the free end of the second air pipe is connected to the bottom of the oxygen enrichment box; the second air pipe is filled with ceramic particles.

[0024] According to the above technical solution, the surface of the ceramic particles used is rough, with many tiny pores and concave-convex surfaces. When oxygen-rich water and bubbles pass through the second air pipe and flow through these ceramic particles, the bubbles will be dispersed into smaller ones. After these tiny bubbles enter the oxygenation box, their floating speed will also decrease, thereby increasing the contact time with water, so that the oxygen in the bubbles can be more fully dissolved into the water, thereby improving the oxygenation effect.

[0025] On the other hand, the present invention also provides a feeding and oxygenation method for a white shrimp aquaculture pond, comprising using the feeding and oxygenation device for a white shrimp aquaculture pond as described above, and the feeding and oxygenation method comprises the following steps: Start the air supply system: Start the air supply component to generate airflow, and the airflow enters the air inlet of the diverter seat through the air outlet; Dividing and mixing: The airflow is directed to the first outlet and the second outlet through the diverter seat. The airflow from the first outlet enters the mixing chamber of the mixing unit, driving the turbofan and the water disturbance unit to rotate, mixing and oxygenating the water entering the mixing chamber; the airflow from the second outlet enters the air distribution plate of the blowing unit through the first air pipe, preparing for the blowing of feed at the feeding port; Feed delivery: put the feed into the feeding box, start the first motor, drive the conveying roller to rotate in the conveying pipe, push the feed to the feeding port, and blow the feed through the airflow ejected from the air outlet of the blowing unit; Optimize bubble distribution: oxygen-rich water and bubbles enter the second air pipe through the tail column at the bottom of the mixing element. The ceramic particles filled in the second air pipe disperse the bubbles into smaller bubbles. Bubble flotation and oxygenation: Oxygen-rich water carries bubbles into the oxygenation box, and the bubbles adhere to the membrane holes of the bubble flotation element. As the number of bubbles increases, the bubble flotation element floats up; at the same time, the second motor drives the first steel frame net to vibrate through the transmission rod, so that the bubbles on the floating bubble flotation element fall off; the bubble flotation element sinks after degassing, and is ready to adhere to bubbles again. This process is repeated to continuously increase oxygen; Circular operation: Continuously run the above steps to form a continuous feeding and oxygenation cycle.

[0026] Beneficial effects of the present invention: 1. The present invention is based on the characteristic that bubbles will float. If oxygen-rich water flows out from the top of the mixing element, part of the oxygen in the airflow may not be fully dissolved in the water and float up and escape, and the effect of fully dissolving oxygen cannot be achieved. In this embodiment, the airflow enters from the top of the mixing element. Although the bubbles generated in the mixing chamber will float up, they will not overflow from the top of the mixing element. In addition, the bubbles will fully contact and dissolve with the water flow in the mixing chamber during the rising process. Finally, the mixed oxygen-rich water and part of the airflow are discharged from the bottom, which can effectively avoid the problem of rapid escape of bubbles.

[0027] 2. The air supply component of the present invention serves as a gas power source to supply gas, and the gas is passed into the diverter seat, and then the diverter seat guides the gas into the mixing component. When the gas enters the mixing component, it can drive the turbofan to rotate, and then drive the water inlet shaft to rotate through the turbofan. When the water inlet shaft rotates, it drives the water disturbance unit to rotate; at the same time, the water flow of the breeding pond enters the water inlet shaft through the water inlet on the water inlet plate, and the water flow is discharged through the water outlet on the water inlet shaft, and then enters the mixing chamber. The water disturbance unit rotates to mix the water flow and air in the mixing chamber. Through the synergistic effect of the turbofan and the water disturbance unit, the water and air are fully mixed, and the oxygen filled in the air flow gradually dissolves in the water to form an oxygen-rich water body, thereby achieving the purpose of increasing oxygen.

[0028] 3. After the oxygen-rich water and a part of the bubbles formed after mixing in the present invention flow out from the bottom of the tail column, the ceramic particles in the second air pipe will disperse the large bubbles into smaller micro bubbles. After the micro bubbles enter the oxygenation box, the floating speed will also be reduced, thereby increasing the contact time with water, so that the oxygen in the bubbles can be more fully dissolved in the water, thereby improving the oxygenation effect.

[0029] 4. The present invention adopts the method of placing the bubble flotation element between the first steel frame net and the second steel frame net, and a plurality of membrane holes are constructed around the bubble flotation element for adhering bubbles. When the oxygen-enriched water carries bubbles into the bottom of the oxygenation box, some bubbles will adhere to the membrane holes of the bubble flotation element. As the number of bubbles adhering to the bubble flotation element increases, the buoyancy of the bubbles gradually increases. When the buoyancy exceeds the gravity of the bubble flotation element itself, the bubble flotation element begins to float up. The vibration generated by the second motor when working is transmitted to the first steel frame net through the transmission rod, causing it to vibrate. When the floating bubble flotation element contacts the vibrating first steel frame net, the bubbles fall off from the membrane holes of the bubble flotation element. After the bubbles fall off, the bubble flotation element begins to sink due to the loss of buoyancy, returns to the initial position, and is ready to adhere to bubbles again. The above process is repeated, and the oxygen in the bubbles is continuously released into the water body during the process of adhering, floating, debubbling and sinking, thereby increasing the dissolved oxygen content of the water body and greatly improving the oxygenation effect.

[0041] like Figure 6 and Figure 7As shown, the water disturbance unit 334 includes a first spoiler fan 3341 and a second spoiler fan 3342, and the first spoiler fan 3341 and the second spoiler fan 3342 are coaxially arranged on the water inlet shaft 335; a plurality of first arc-shaped blades 3341a are formed on the first spoiler fan 3341, and each first arc-shaped blade 3341a is twisted and fixed on the first spoiler fan 3341 along a first direction; a plurality of second arc-shaped blades 3342a are formed on the second spoiler fan 3342, and each second arc-shaped blade 3342a is twisted and fixed on the second spoiler fan 3342 along a second direction; wherein the first direction is opposite to the second direction; in the present embodiment, the first direction is preferably clockwise and the second direction is counterclockwise. According to the above technical solution, when the water inlet shaft 335 rotates, the first spoiler fan 3341 and the second spoiler fan 3342 are also driven to rotate. The torsion direction of the first arc-shaped blade 3341a is opposite to the torsion direction of the second arc-shaped blade 3342a. The design of opposite blade directions can produce different fluid dynamic effects; when the first spoiler fan 3341 stirs the airflow and water flow, the first arc-shaped blade 3341a will stir the fluid in one direction to dissolve oxygen; then, when the second spoiler fan 3342 stirs the airflow and water flow, the second arc-shaped blade 3342a stirs the fluid in the opposite direction. This reverse stirring can further enhance the turbulence and shear force inside the fluid, thereby forming a complex flow field in the water body, which is conducive to the full mixing between gas and liquid, helps to promote the overall circulation and flow of the water body, and increases the dissolved oxygen content in the water body, providing a sufficient oxygen environment for aquatic organisms such as white shrimp.

[0042] like Figure 6 , Figure 7 and Fig.11As shown, the water disturbance unit 334 also includes a stirring frame head 3343, which is coaxially fixed on the water inlet shaft 335; the stirring frame head 3343 includes a coaxially arranged inner frame and outer frame, and a plurality of holes are arranged on the inner frame and the outer frame. According to the above technical solution, the water flow in the pond first flows out through the water outlet 3351 on the water inlet shaft 335 to guide the mixing chamber 3321. When the water flow enters the mixing chamber 3321, the water flow first contacts the inner frame of the mixing frame head 3343. The inner frame is provided with a plurality of holes. During the rotation of the inner frame, these holes allow the water flow to pass through and preliminarily divert and refine the water flow. The water flow forms a smaller water flow beam inside the inner frame and flows out through the holes to enter the outer frame area; the water flow out of the inner frame then enters the outer frame. The outer frame is also provided with a plurality of holes. These holes further disperse and mix the water flow. Since the water flow has been preliminarily refined in the inner frame, a more uniform and fine water flow distribution can be formed in the outer frame. The mixing frame head 3343 is coaxially fixed on the water inlet shaft 335 and rotates with the rotation of the water inlet shaft 335. During the rotation, the mixing frame head 3343 will drive the surrounding airflow and water flow to rotate together, generating centrifugal force. The centrifugal force generated by the rotation will cause the water flow and airflow to flow from the center of the mixing chamber 3321 to the surrounding areas of the mixing chamber 3321. The centrifugal force has the effect of promoting the breakage and dispersion of bubbles in the mixing chamber 3321, so that oxygen can be dissolved in the water more quickly for mixing and oxygenation. Finally, the oxygenated water flow (oxygen-enriched water) flows out through the bottom of the mixing element 332 into the breeding pond.

[0043] In this embodiment, the water flow of the breeding pond enters the water inlet shaft 335 through the water inlet 3311a on the water inlet plate 331, and the water flow is discharged through the water outlet 3351 on the water inlet shaft 335, and then enters the mixing chamber 3321. The water disturbance unit 334 rotates to mix the water flow and air in the mixing chamber 3321. The airflow drives the turbofan 333 to rotate, and then drives the water disturbance unit 334 and the stirring frame head 3343 on the water inlet shaft 335 to work together, and the water and air are fully mixed. The oxygen filled in the airflow gradually dissolves in the water to form an oxygen-rich water body, thereby achieving the purpose of oxygenation. Moreover, the present invention is based on the characteristic that bubbles will float up. If the oxygen-rich water flows out from the top of the mixing element 332, it may cause part of the oxygen in the airflow to fail to fully dissolve in the water and float up and escape, and the effect of fully dissolving oxygen cannot be achieved. In this embodiment, the airflow enters from the top of the mixing element 332. Although the bubbles generated in the mixing chamber 3321 will float up, they will not overflow from the top of the mixing element 332. In addition, the bubbles will fully contact and dissolve with the water flow in the mixing chamber 3321 again during the rising process. Finally, the mixed oxygen-rich water and some bubbles are discharged from the bottom, which can effectively avoid the problem of rapid escape of bubbles. like Figure 3 and Figure 4As shown, the feeding mechanism 2 includes a feeding box 21, a conveying pipe 22, a first motor 23 and a conveying roller 24. The conveying pipe 22 is arranged at the bottom of the feeding box 21 for conveying feed. The conveying roller 24 is coaxially arranged in the conveying pipe 22. The first motor 23 is coaxially connected to the end of the conveying roller 24 to drive the conveying roller 24 to rotate. A feeding port 221 is arranged on the side of the conveying pipe 22 away from the first motor 23. According to the above technical solution, after the first motor 23 is started, the conveying roller 24 is driven to rotate in the conveying pipe 22 through the coaxial connection. The rotation of the conveying roller 24 provides power for the conveying of feed. The feed is put into the feeding box 21. As the conveying roller 24 rotates, the feed is gradually pushed into the conveying pipe 22. The conveying roller 24 in the conveying pipe 22 continues to push the feed forward until the feed is discharged from the feeding port 221, thereby achieving the purpose of feeding the white shrimp.

[0044] Combined with Figure 3 , Figure 4 and Figure 8 As shown, the present embodiment further includes an air blowing unit 4, which is arranged at the bottom of the feeding port 221 and is used for blowing the feed in the feeding port 221; the air blowing unit 4 includes an air distribution plate 41 and a first air pipe 42, an air cavity 411 and a plurality of air outlet holes 412 are provided in the air distribution plate 41, and each air outlet hole 412 is connected to the air cavity 411; one end of the first air pipe 42 is connected to the air cavity 411, and the other end of the first air pipe 42 is connected to the second air outlet 323; the gas enters the air cavity 411 of the air distribution plate 41 through the first air pipe 42, and when the feed is discharged from the feeding port 221, the air blowing unit 4 at the bottom of the air distribution plate 41 starts to work, and the gas ejected from the air outlet holes 412 blows the feed, so that the feed is more evenly distributed in the pond under the drive of the air flow, so that the feed is more evenly distributed in the pond, the growth difference caused by competing for food is reduced, and it is helpful to reduce the accumulation and waste of feed in the pond.

[0045] A switch 43 is provided on the first air pipe 42, and the switch 43 can be turned on or off; the switch 43 provided on the first air pipe 42 is used to control the flow rate of the gas and the switch 43. By adjusting the opening degree of the switch 43, the strength and range of blowing the feed can be controlled to adapt to different breeding needs and environmental conditions.

[0046] Furthermore, a one-way valve 44 is provided in the first flow channel 3312a and / or the second flow channel 335a, and the one-way valve 44 is used for one-way communication from the water inlet 3311a to the mixing chamber 3321. Preferably, the one-way valve 44 is provided in the second flow channel 335a to ensure that the water can only flow in a set direction (i.e., from the water inlet 3311a to the mixing chamber 3321), effectively preventing the water from flowing back during the mixing process or when the pressure changes.

[0047] As a preferred embodiment, Figure 2, Figure 3 and Fig.14 As shown, it also includes an oxygenation box 5 fixedly arranged on the diverter seat 32, the top of the oxygenation box 5 is open, and a first steel frame net 51 and a second steel frame net 52 are arranged in parallel with each other in the oxygenation box 5, and a plurality of bubble flotation elements 53 are arranged between the first steel frame net 51 and the second steel frame net 52, and a plurality of membrane holes 531 are constructed around the bubble flotation element 53 for adhering bubbles; after the bubble flotation element 53 is saturated with bubbles, the buoyancy of the bubbles can drive the bubble flotation element 53 to float; the average density of the bubble flotation element 53 is greater than the density of water; as Preferably, the surface of the bubble flotation element 53 is hydrophobic. The bubble flotation element 53 of this embodiment is made of a honeycomb aluminum plate to form a cubic structure. The surface of the cubic structure has inwardly concave membrane holes 531. The honeycomb aluminum plate itself has a dense oxide film on the surface. The honeycomb structure is relatively light in material. Adjacent membrane holes 531 are in an isolated state, and bubbles are not easy to merge with each other after adsorption. Combined with the actual manufacturing process, the thickness of the honeycomb aluminum interlayer can be processed to the thinnest 0.04 mm, and the thickness of the honeycomb aluminum plate can be processed to the thinnest 1.0 mm.

[0048] The first steel frame net 51 is disposed above the second steel frame net 52 ; a transmission rod 54 is connected to the first steel frame net 51 , and the other end of the transmission rod 54 is connected to the second motor 313 . The bubble flotation element 53 is placed between the first steel frame net 51 and the second steel frame net 52, and is surrounded by a plurality of membrane holes 531 for adhering bubbles. When the oxygen-enriched water carries bubbles into the bottom of the oxygenation box 5, some bubbles will adhere to the membrane holes 531 of the bubble flotation element 53. As the number of bubbles adhering to the bubble flotation element 53 increases, the buoyancy of the bubbles gradually increases. When the buoyancy exceeds the gravity of the bubble flotation element 53 itself, the bubble flotation element 53 begins to float. The vibration generated by the second motor 313 when working is transmitted to the first steel frame net 51 through the transmission rod 54, causing it to vibrate. When the floating bubble flotation element 53 contacts the vibrating first steel frame net 51, the bubbles fall off from the membrane holes 531 of the bubble flotation element 53. After the bubbles fall off, the bubble flotation element 53 begins to sink due to the loss of buoyancy and falls back to the second steel frame net 52, ready to adhere to bubbles again. The above process is repeated over and over again, and the oxygen in the bubbles is continuously released into the water body during the process of adhesion, floating, degassing and sinking, thereby increasing the dissolved oxygen content of the water body.

[0049] Furthermore, if Figure 5 , Figure 6 and Figure 7 As shown, the bottom of the mixing element 332 is provided with a tail column 336 connected to the mixing chamber 3321, along the length direction of the mixing element 332 (that is, Figure 5The cross section of the tail column 336 gradually decreases from top to bottom; the tail column 336 is connected to a second air pipe 6, and the free end of the second air pipe 6 is connected to the bottom of the oxygenation box 5; the second air pipe 6 is filled with ceramic particles. The preferred ceramic particles are ceramic beads. According to the above technical solution, the surface of the ceramic beads used is rough, with many tiny pores and concave-convex surfaces. When oxygen-rich water and bubbles pass through the second air pipe 6 and flow through these ceramic particles, the bubbles will be dispersed into smaller ones. After these tiny bubbles enter the oxygenation box 5, their buoyancy speed will be correspondingly reduced compared to that of large bubbles, thereby increasing the contact time between the bubbles and the water, so that the oxygen in the bubbles can be more fully dissolved in the water, thereby improving the oxygenation effect.

[0050] On the other hand, the present invention also provides a feeding and oxygenation method for a white shrimp aquaculture pond, comprising using the feeding and oxygenation device for a white shrimp aquaculture pond as described above, and the feeding and oxygenation method comprises the following steps: Start the air supply system: Start the air supply component 31 to generate airflow, and the airflow enters the air inlet 321 of the diverter seat 32 through the air outlet 315; Dividing and mixing: The airflow is directed to the first air outlet 322 and the second air outlet 323 through the diverting seat 32. The airflow of the first air outlet 322 enters the mixing chamber 3321 of the mixing unit 33, and drives the turbofan 333 and the water disturbance unit 334 to rotate, so as to mix and oxygenate the water entering the mixing chamber 3321. The airflow of the second air outlet 323 enters the air distribution plate 41 of the blowing unit 4 through the first air pipe 42, so as to prepare for blowing and feeding the feed at the feeding port 221. Feed delivery: put the feed into the feeding box 21, start the first motor 23, drive the conveying roller 24 to rotate in the conveying pipe 22, push the feed to the feeding port 221, and blow the feed through the airflow ejected from the air outlet 412 of the blowing unit 4; Optimizing bubble distribution: oxygen-enriched water and bubbles enter the second air pipe 6 through the tail column 336 at the bottom of the mixing element 332, and the ceramic particles filled in the second air pipe 6 disperse the bubbles into smaller bubbles; Bubble flotation and oxygenation: The oxygen-rich water carries bubbles into the oxygenation box 5, and the bubbles adhere to the membrane holes 531 of the bubble flotation element 53. As the number of bubbles increases, the bubble flotation element 53 floats up; at the same time, the second motor 313 drives the first steel frame net 51 to vibrate through the transmission rod 54, so that the bubbles on the floating bubble flotation element 53 fall off; the bubble flotation element 53 sinks after degassing, and is ready to adhere to bubbles again. This process is repeated to continuously increase oxygen; Circular operation: Continuously run the above steps to form a continuous feeding and oxygenation cycle. Through precise air supply control, reasonable diversion and mixing design, accurate feed delivery, and optimized bubble distribution and flotation mechanism, the system can provide sufficient oxygen and a suitable growth environment for aquatic organisms such as white shrimp, promoting their healthy growth and reproduction.
