Description

Technical Field

[0001] This invention belongs to the field of intensive aquaculture wastewater recycling technology, and particularly relates to an integrated box-type intensive aquaculture wastewater recycling system. Background Technology

[0002] High-density aquaculture, also known as intensive aquaculture, is a technology that achieves high-efficiency aquatic animal production within a limited water space by increasing stocking density, optimizing the aquaculture environment, improving feed utilization, and enhancing management. It has become one of the key aquaculture models promoted in Ningxia. The aim is to increase yield per unit area or volume of water to meet market demand for aquatic products. However, high-density aquaculture involves high dissolved oxygen consumption, requiring aeration equipment, and fecal residue easily pollutes the aquaculture tank environment.

[0003] Chinese patent publication number CN112136759B discloses a device for removing fish feces and fish food residue from fishpond water. The device includes a fishpond, a Venturi aerator, a primary sewage discharger, an electrical control box, a secondary waste separation tank, and a floating debris filter. The Venturi aerator oxygenates the water and promotes water rotation in the circular fishpond, causing fish feces and fish food residue settled at the bottom to accumulate in the center. The floating debris filter collects and cleans floating debris in a timely manner. The waste accumulated in the center of the pond is first sucked into the secondary waste separation tank for further separation. The device removes wastewater with high levels of fish feces and fish food residue, while the remaining clearer water returns to the fishpond. This allows fish feces and fish food residue to be removed from the fishpond before they ferment and pollute the water. However, in actual use, the oxygenation process is prone to problems due to the dense aquaculture environment, resulting in insufficient dispersion and a small transmission range, affecting the uniformity of oxygen distribution. Furthermore, the aeration airflow disperses the fish feces and fish food residue, hindering collection and recycling. Therefore, there is room for improvement. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that oxygen is not sufficiently dispersed and concentrated when it is introduced into the water during aeration, resulting in a small conduction range and affecting the uniformity of propagation, by proposing an integrated box-type intensive aeration tailwater recycling system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated box-type intensive aquaculture wastewater recycling system includes an aquaculture tank and a purification ditch. A sedimentation tank is connected to the bottom of the aquaculture tank. The sedimented waste in the sedimentation tank is discharged into the purification ditch through a pipe. A filtration mechanism is connected between the aquaculture tank and the sedimentation tank. An oxygen delivery mechanism is provided on the periphery of the inner cavity of the aquaculture tank. The oxygen delivery mechanism includes an oxygen delivery tank. Multiple oxygen delivery ring pipes are arranged in an array along the depth direction on both sides of the outer side of the oxygen delivery tank, and multiple oxygen delivery nozzles are connected to the inner side of the oxygen delivery ring pipes.

[0007] Multiple guiding mechanisms are arranged around the inner cavity of the aquaculture tank, and these guiding mechanisms are located on one side of multiple longitudinally adjacent oxygen supply nozzles. The oxygen is guided to be distributed within the aquaculture tank through these guiding mechanisms.

[0008] As a further description of the above technical solution:

[0009] The guiding mechanism includes a sliding rod, both sides of which are connected to one side of the aquaculture tank cavity via fixing plates. Multiple rotating sleeves are rotatably connected to the outer side of the sliding rod. A fixing frame is connected to one side of the rotating sleeve. A guiding cover is inserted inside the fixing frame. A guide pipe is connected to the other end of the guiding cover. The other end of the guide pipe corresponds to an oxygen supply nozzle on one side.

[0010] As a further description of the above technical solution:

[0011] A bearing seat is connected to one side of the inner cavity of the guide cover, and a rod is rotatably connected inside the bearing seat. A turbine is connected to one end of the rod and the turbine is located inside the guide pipe. A guide wheel is connected to the other side of the rod, and oxygen is pumped in by the turbine driving the guide wheel.

[0012] As a further description of the above technical solution:

[0013] A force-bearing plate is connected to one side of the rotating sleeve, and the force-bearing plate is perpendicular to the fixed frame. A disturbance rod is connected between the two longitudinally adjacent fixed frames. Multiple disturbance blocks are rotatably connected to one side of the disturbance rod along the height direction. The disturbance rod and the disturbance blocks are driven to oscillate and guide the cover by the movement of fish.

[0014] As a further description of the above technical solution:

[0015] The filtration mechanism includes a sedimentation tank connected to the inside of a sedimentation bottom box. The inner cavity of the sedimentation tank is arc-shaped, and a suction pipe is connected to the center point of the arc of the sedimentation tank. The suction pipe passes through the sedimentation bottom box and extends to the purification ditch.

[0016] As a further description of the above technical solution:

[0017] A filter plate is connected to the top of the sedimentation tank. The filter plate has multiple filter holes on its top and a sweeping plate is rotatably connected to the top of the filter plate. The sweeping plate is connected to a drive unit via a rod. One side of the drive unit is connected to the top of the sedimentation tank via a support plate.

[0018] As a further description of the above technical solution:

[0019] The sweeping plate has multiple grooves arrayed on one side, and a moving rod is slidably connected to the inner cavity of the groove. A sweeping block is connected to the bottom end of the moving rod, and a spring is connected to the top of the moving rod. The two ends of the spring are respectively connected to the corresponding positions on the top two sides of the sweeping plate.

[0020] As a further description of the above technical solution:

[0021] The top of the sedimentation tank is connected to a slide rail groove, and both ends of the sweeping plate are rotatably connected to pulleys, which are slidably connected in the slide rail groove.

[0022] As a further description of the above technical solution:

[0023] The aquaculture tank is equipped with a cover on top, and the cover is connected to the top of the aquaculture tank by a snap fastener. Multiple support legs are connected to the bottom periphery of the aquaculture tank.

[0024] As a further description of the above technical solution:

[0025] The top of the oxygenation tank is connected to an external oxygenation device via a delivery pipe, and a water quality detection sensor is installed inside the aquaculture tank.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, through the design of aquaculture tanks and sedimentation tanks, when the fish in the aquaculture tanks are fed and produce food residue and feces, the food residue and feces can settle to the bottom filtration mechanism. At this time, the food residue and feces can be discharged through the suction pipe and sent into the purification ditch. Some of the feces and food residue sent into the purification ditch can be used as food for farmed organisms such as loach or crabs. The removal of fish feces and a small amount of feed through the purification ditch allows the initially purified water to enter the paddy field on one side for secondary purification. This is beneficial for improving the purification effect by intensively discharging and recycling multiple aquaculture tanks.

[0028] 2. In this invention, through the designed guiding mechanism, when the oxygen is delivered to the oxygenation tank via the pumping equipment, multiple annular oxygen nozzles uniformly deliver oxygen into the aquaculture tank. The oxygen enters the inlet pipe and mixes with the water flow to drive the turbine to rotate. The turbine rotation drives the rear guide wheel to rotate, fully mixing the water and the delivered oxygen before sending it into the aquaculture tank. The mixed water mixture improves the uniformity of oxygen distribution, increasing the oxygen supply required by fish in high-density aquaculture. When swimming fish come into contact with the force plate, the force plate can rotate outside the slide rod via a rotating sleeve. The rotating sleeve can drive the fixed frame to rotate and push one side of the guide cover to partially deflect. The movement of the guide cover creates vibration disturbance in the water, which can increase the oscillation of the input oxygen into the water, increase the dissolved oxygen concentration, and improve the uniformity of dissolved oxygen diffusion. At the same time, through the turbulent diffusion of the water, oxygen can be transferred more effectively.

[0029] 3. In this invention, through the designed filtration mechanism, when fish feces and feed settle to the bottom of the aquaculture tank, the settled fish feces and feed can enter the sedimentation tank through the holes at the top of the filter plate. Furthermore, the settled fish feces and feed can slowly gather and concentrate through the arc-shaped bottom wall of the sedimentation tank. The sedimentation tank separates the fish living space from the feces sedimentation space, preventing the fermentation of feces in the aquaculture tank from affecting the biological activity of the farmed fish. The rotating sweeping plate can sweep the accumulated fish feces and impurities into the holes of the filter plate, improving the stability of the internal space of the aquaculture tank by reducing the accumulation of fish feces on the top of the filter plate. When the sweeping plate moves and comes into contact with hard feed, the sweeping block can be moved upward by the moving rod, avoiding excessive compression that could damage the filter plate and improving the scraping treatment effect.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-11The present invention provides a technical solution: an integrated box-type dense aquaculture wastewater recycling system, including an aquaculture tank 1 and a purification ditch. The bottom of the aquaculture tank 1 is connected to a sedimentation tank 6. The sedimented waste in the sedimentation tank 6 is discharged to the purification ditch through a pipe. A filter mechanism 4 is connected between the aquaculture tank 1 and the sedimentation tank 6. An oxygen delivery mechanism 2 is provided on the periphery of the inner cavity of the aquaculture tank 1. The oxygen delivery mechanism 2 includes an oxygen delivery tank 202. Multiple oxygen delivery ring pipes 201 are arranged in an array along the depth direction on both sides of the outer side of the oxygen delivery tank 202, and multiple oxygen delivery nozzles 203 are connected to the inner side of the oxygen delivery ring pipes 201.

[0045] Multiple guiding mechanisms 3 are arranged around the inner cavity of the aquaculture tank 1, and the guiding mechanisms 3 are located on one side of multiple longitudinally adjacent oxygen supply nozzles 203. The guiding mechanisms 3 guide oxygen to be distributed in the aquaculture tank 1.

[0046] The top of the oxygenation tank 202 is connected to an external oxygenation device via a delivery pipe 204, and a water quality detection sensor is installed inside the aquaculture tank 1.

[0047] Specifically: Through the designed aquaculture tank 1 and sedimentation tank 6, when the fish in the aquaculture tank 1 are fed and produce food residue and feces, the food residue and feces can settle into the bottom filtration mechanism. At this time, the food residue and feces can be discharged through the suction pipe 8 and sent into the purification ditch. Some of the feces and food residue sent into the purification ditch can be used as food for farmed organisms such as loach or crabs. Thus, the fish feces and a small amount of feed can be removed through the purification ditch, and the initially purified water can enter the paddy field on one side for secondary purification. This is conducive to improving the purification effect by intensively discharging and recycling multiple sets of aquaculture tanks 1.

[0048] Please see Figure 3 , 7 -9, the guiding mechanism 3 includes a slide rod 308. Both sides of the slide rod 308 are connected to one side of the inner cavity of the aquaculture tank 1 through fixing plates 309. Multiple rotating sleeves 303 are rotatably connected to the outer side of the slide rod 308. A fixing frame 305 is connected to one side of the rotating sleeve 303. A guide cover 301 is inserted inside the fixing frame 305. The other end of the guide cover 301 is connected to a guide pipe 311. The other end of the guide pipe 311 corresponds to an oxygen supply nozzle 203 on one side.

[0049] A bearing seat is connected to one side of the inner cavity of the guide cover 301, and a rod is rotatably connected inside the bearing seat. A turbine 310 is connected to one end of the rod, and the turbine 310 is located inside the guide pipe 311. A guide wheel 302 is connected to the other side of the rod. The guide wheel 302 is driven by the turbine 310 to disperse and pump oxygen in.

[0050] A force-bearing plate 304 is connected to one side of the rotating sleeve 303, and the force-bearing plate 304 is perpendicular to the fixing frame 305. A disturbance rod 306 is connected between the two longitudinally adjacent fixing frames 305. Multiple disturbance blocks 307 are rotatably connected to one side of the disturbance rod 306 along the height direction. The disturbance rod 306 and the disturbance blocks 307 are driven to vibrate the guide cover 301 by the swimming of fish. Preferably, the disturbance rod 306 and the disturbance blocks 307 are covered with soft materials such as rubber to avoid fish collision and injury.

[0051] Specifically: Through the designed guiding mechanism 3, when oxygen needs to be added to the aquaculture tank 1, the delivery pipe 204 can be pumped to the oxygenation tank 202. Multiple sample delivery ring pipes connected to the periphery of the oxygenation tank 202 can deliver oxygen evenly to the aquaculture tank 1 through multiple annular oxygen delivery nozzles 203. The oxygen delivered to the aquaculture tank 1 can first come into contact with the inlet pipe 311. The oxygen entering the inlet pipe 311 can drive the turbine 310 to rotate by mixing with the water flow. The rotation of the turbine 310 can drive the rear guide wheel 302 to rotate, thereby fully mixing the water liquid with the delivered oxygen before delivering it into the aquaculture tank 1. This is beneficial to improve the uniformity of oxygen distribution through the mixed water liquid mixture, thereby improving the oxygen supply needs of fish in high-density aquaculture conditions.

[0052] Furthermore, through the designed force plate 304 and rotating sleeve 303, when fish swim in the aquaculture tank 1, the force plate 304 can rotate outside the slide rod 308 via the rotating sleeve 303 when the swimming fish come into contact with the force plate 304. The force plate 304 is also covered with soft materials such as rubber. The rotating sleeve 303 can drive the fixed frame 305 to rotate and push the guide cover 301 on one side to partially deflect. This is beneficial to achieve vibration disturbance in the water body through the movement of the guide cover 301. The vibration disturbance can improve the oscillation of the input oxygen into the water body, increase the dissolved oxygen concentration, and improve the uniformity of dissolved oxygen diffusion. At the same time, through the turbulent diffusion of the water body, oxygen can be transferred more effectively.

[0053] Please see Figures 4-5 , Figures 10-11 The filtration mechanism 4 includes a sedimentation tank 401, which is connected to the inside of the sedimentation bottom box 6. The inner cavity of the sedimentation tank 401 is arc-shaped, and the center point of the arc of the sedimentation tank 401 is connected to a suction pipe 8, which extends through the sedimentation bottom box 6 to the purification ditch.

[0054] Specifically: Through the designed filtration mechanism 4, when fish feces and feed settle to the bottom of the aquaculture tank 1, the fish feces and feed sediment can enter the sedimentation tank 401 through the top holes of the filter plate 402. The fish feces and feed sediment can slowly gather and concentrate through the arc-shaped bottom wall of the sedimentation tank 401. After concentration, the fish feces and feed sediment are pumped out to the purification ditch by the external pump body through the suction pipe 8, or directly discharged by the water body gravity through the valve of the suction pipe 8. This is beneficial to separate the fish living space and the feces sedimentation space by setting the sedimentation tank 401, and avoid the fermentation of feces in the aquaculture tank 1 from affecting the biological activity of the farmed fish.

[0055] A filter plate 402 is connected to the top of the sedimentation tank 401. The filter plate 402 has multiple filter holes on its top. A sweeping plate 405 is rotatably connected to the top of the filter plate 402. The sweeping plate 405 is connected to a drive unit 409 via a rod. One side of the drive unit 409 is connected to the top of the sedimentation tank 401 via a support plate 404.

[0056] Multiple grooves are arrayed on one side of the sweeping plate 405, and a moving rod 407 is slidably connected to the inner cavity of the groove. A sweeping block 406 is connected to the bottom end of the moving rod 407, and a spring piece 408 is connected to the top of the moving rod 407. The two ends of the spring piece 408 are respectively connected to the corresponding positions on the top two sides of the sweeping plate 405.

[0057] The top of the sedimentation tank 401 is connected to the slide rail groove 403, and both ends of the sweeping plate 405 are rotatably connected to pulleys 410, which are slidably connected in the slide rail groove 403.

[0058] The top of the aquaculture tank 1 may be equipped with a cover 5, which is connected to the top of the aquaculture tank 1 by a snap-fit. Multiple support legs 7 are connected to the bottom perimeter of the aquaculture tank 1. It can be closed for rearing when necessary, such as in winter when it is cold, which can relatively increase the rearing temperature. Alternatively, some shrimp do not like light, so the light intensity of the aquaculture tank can be controlled by covering the tank and appropriately adjusting the material of the cover, such as the light transmittance.

[0059] Specifically: Through the design of the sweeping plate 405, when some fish feces and impurities accumulate at the top of the filter plate 402 where no holes are made, the drive unit 409 can drive the bottom rod to rotate. The rotation of the rod can drive the sweeping plate 405 to rotate at the top of the filter plate 402. The rotating sweeping plate 405 can sweep the accumulated fish feces and impurities into the holes of the filter plate 402. By reducing the accumulation of fish feces at the top of the filter plate 402, the stability of the internal space of the aquaculture tank 1 is improved. Furthermore, through the design of the sweeping plate 405, the sweeping plate 405 can rotate in the slide rail groove 403 through the pulleys 410 on both sides, which helps to improve the movement stability of the sweeping plate 405 and avoid the interference of fish feces and impurities accumulation, which would cause the axial jump of the sweeping plate 405 to affect the scraping effect.

[0060] Furthermore, through the design of the sweeping block 406 and the spring plate 408, when the sweeping plate 405 moves and comes into contact with hard feed, the sweeping block 406 can be forced to move upward through the moving rod 407, avoiding excessive squeezing that could damage the filter plate 402. At the same time, through the design of the spring plate 408, when the moving rod 407 moves, it can squeeze the spring plate 408. The spring plate 408 can use its own elasticity to keep the bottom sweeping block 406 fully attached to the filter plate, which is beneficial to improving the scraping treatment effect. The drive unit 409 can be a drive motor that drives the rod body to rotate.

[0061] Working principle: When the fish in the aquaculture tank 1 are fed, food residue and feces are produced. The food residue and feces settle to the bottom filter mechanism. They are then pumped into the purification ditch by suction pipe 8 or by water pressure discharge. Some of the feces and food residue sent into the purification ditch can be used as food for farmed organisms such as loach or crabs. The purification ditch removes fish feces and a small amount of feed, allowing the initially purified water to enter the paddy field on one side for secondary purification. This achieves full utilization of aquaculture wastewater and zero discharge.

[0062] When oxygenating the aquaculture tank 1, the delivery pipe 204 is pumped to the oxygenation tank 202 through the pumping equipment. Multiple sample delivery ring pipes connected to the periphery of the oxygenation tank 202 deliver oxygen evenly to the aquaculture tank 1 through multiple annular oxygen delivery nozzles 203. The oxygen delivered into the aquaculture tank 1 first comes into contact with the inlet pipe 311. The oxygen entering the inlet pipe 311 drives the turbine 310 to rotate by mixing with the water flow. The rotation of the turbine 310 drives the rear guide wheel 302 to rotate, and the water liquid and the delivered oxygen are fully mixed before being delivered into the aquaculture tank 1. When the fish swim in the aquaculture tank 1, when the swimming fish come into contact with the force plate 304, the force plate 304 rotates outside the slide rod 308 through the rotating sleeve 303. The rotating sleeve 303 drives the fixed frame 305 to rotate and pushes the guide cover 301 on one side to partially deflect, thus disturbing the vibration in the water.

[0063] When fish feces and feed settle to the bottom of the aquaculture tank 1, the fish feces and feed sediment enter the sedimentation tank 401 through the top hole of the filter plate 402. The fish feces and feed sediment slowly gather and concentrate through the arc-shaped bottom wall of the sedimentation tank 401. After being concentrated, the fish feces and feed sediment are discharged to the purification ditch through the external pump body to the suction pipe 8.

[0064] When some fish feces and impurities accumulate at the top of the filter plate 402 where no holes are made, the drive unit 409 drives the bottom rod to rotate. The rotation of the rod causes the sweeping plate 405 to rotate at the top of the filter plate 402. The rotating sweeping plate 405 sweeps the accumulated fish feces and impurities into the holes of the filter plate 402. When the sweeping plate 405 moves and comes into contact with hard feed, the sweeping block 406 is forced to move upward through the moving rod 407, avoiding excessive compression that could damage the filter plate 402. At the same time, through the designed spring 408, when the moving rod 407 moves, it is squeezed. The spring 408 uses its own elasticity to keep the bottom sweeping block 406 in full contact with the filter plate.
