Description

Technical Field

[0001] The invention belongs to the technical field of intensive aquaculture tail water circulation, and in particular relates to an integrated box-type intensive aquaculture tail water circulation utilization system. Background Art

[0002] High-density aquaculture technology, also known as intensive aquaculture technology, is a technology that achieves efficient production of aquatic animals in limited water space by increasing the breeding density, optimizing the breeding environment, improving feed utilization and management level, etc. It has become one of the several key aquaculture models promoted in Ningxia. The purpose is to increase the output per unit area or unit volume of water to meet the market demand for aquatic products. However, due to the high-density breeding process, the consumption of dissolved oxygen is large, and oxygenation equipment is required, and fecal residues are easy to pollute the environment in the breeding tank.

[0003] The Chinese patent document publication number CN112136759B discloses a device for removing fish feces and fish food residues from fish pond water, comprising: a fish pond, a venturi aerator, a primary sewage discharger, an electric control box, a secondary sewage separation barrel, and a floating object filter. The venturi aerator oxygenates the water and causes the water to rotate in the circular fish pond, so that the fish feces and fish food residues deposited on the bottom of the pond are gathered in the center of the pond. The floating object filter collects and cleans the floating objects in time, and the sewage gathered in the center of the pond is first sucked into the secondary sewage separation barrel and then separated. The sewage with high content of fish feces and fish food residues is discharged by using relevant equipment, and the remaining relatively clear water returns to the fish pond, so that the fish feces and fish food residues can be discharged out of the fish pond in time before they ferment and pollute the water quality. However, in actual use, when the water is oxygenated, it is easy to cause the oxygen to be not dispersed and concentrated enough when it is sent in due to the dense breeding environment, resulting in a small conduction range, affecting the uniformity of propagation, and the aeration airflow blows away the fish feces and fish food residues, which is not conducive to collection and recycling, and there is room for improvement.

[0027] 1.

At this time, part of the feces and food residues sent to the purification ditch can be used as food for cultured organisms such as loaches or crabs.

[0028] 2.

When the swimming fish contacts the force-bearing plate, the force-bearing plate can be rotated outside the sliding rod through the rotating sleeve, and the rotating rotating sleeve can drive the fixed frame to rotate and push one side of the guide cover to partially deflect. The vibration disturbance in the water body can be achieved through the movement of the guide cover, and the oscillation of the input oxygen into the water body can be improved through the vibration disturbance.

At the same time, through the turbulent diffusion of the water body, oxygen can be more effectively transferred.

[0029] 3. In the present invention, through the designed filtering mechanism, when fish feces and feed in the water body are precipitated to the bottom side of the breeding water tank, the fish feces and feed precipitation can enter the sedimentation tank through the holes on the top of the filter plate, and the fish feces and feed precipitation can be slowly gathered and concentrated through the arc-shaped bottom wall in the sedimentation tank. The setting of the sedimentation tank divides the fish living space and the feces precipitation space, so as to avoid the fermentation of feces in the breeding water tank and affect the biological activity of farmed fish. The rotating sweeping plate can sweep the accumulated fish feces impurities into the holes of the filter plate, and the stability of the internal space of the breeding water tank is improved by reducing the accumulation of fish feces on the top of the filter plate. When the sweeping plate moves and contacts with hard feed, the sweeping block can be forced to move upward through the moving rod to avoid damage to the filter plate caused by excessive squeezing, thereby improving the scraping and sweeping treatment effect.

[0048] See also Figure 3 , 7 -9, the guide mechanism 3 includes a slide bar 308, both sides of the slide bar 308 are connected to one side of the inner cavity of the aquaculture water tank 1 through a fixing plate 309, the outer side of the slide bar 308 is rotatably connected to a plurality of rotating sleeves 303, one side of the rotating sleeve 303 is connected to a fixing frame 305, a guide cover 301 is inserted into the fixing frame 305, the other end of the guide cover 301 is connected to a guide pipe 311, and the other end of the guide pipe 311 corresponds to one side of the oxygen supply nozzle 203;

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

[0050] A force-bearing plate 304 is connected to one side of the rotating sleeve 303, and the force-bearing plate 304 is vertically arranged with the fixing frame 305, and a disturbance rod 306 is connected between the two longitudinally adjacent fixing frames 305. A plurality of disturbance blocks 307 are connected to one side of the disturbance rod 306 for rotation along the height direction.

Preferably, the disturbance rod 306 and the disturbance block 307 are wrapped with soft materials such as rubber to prevent fish from being injured by collision.

[0051] Specifically: through the designed guiding mechanism 3, when it is necessary to supplement oxygen in the aquaculture water tank 1, the delivery pipe 204 can be delivered to the oxygen delivery tank 202 through the pumping equipment, and the multiple sample delivery ring tubes connected to the peripheral side of the oxygen delivery tank 202 can evenly deliver oxygen to the aquaculture water tank 1 through the multiple annular oxygen delivery nozzles 203, and the oxygen delivered to the aquaculture water tank 1 can first contact with the introduction pipe 311, and the oxygen entering the introduction pipe 311 can drive the turbine 310 to rotate by mixing with the water flow, and the rotation of the turbine 310 can drive the rear guide wheel 302 to rotate, so that the water liquid and the delivered oxygen can be fully mixed and then delivered to the aquaculture water tank 1, which is beneficial to improve the uniformity of oxygen distribution through the mixed water-liquid mixture and improve the oxygen supply needs of fish under high-density aquaculture;

[0052] Furthermore, through the designed force-bearing plate 304 and rotating sleeve 303, when the fish swims in the breeding tank 1, when the swimming fish contacts the force-bearing plate 304, the force-bearing plate 304 can be rotated outside the slide bar 308 through the rotating sleeve 303. The force-bearing plate 304 is also wrapped with soft materials such as rubber. The rotating rotating sleeve 303 can drive the fixed frame 305 to rotate and push one side of the guide cover 301 to partially deflect, which is beneficial to achieve vibration disturbance in the water body through the movement of the guide cover 301.

[0053] See also Figure 4-Figure 5 , Figure 10-11 The filtering mechanism 4 includes a sedimentation tank 401, which is connected to the inner side 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, and the suction pipe 8 passes through the sedimentation bottom box 6 and extends to the purification ditch;

[0054] Specifically: through the designed filtering mechanism 4, when fish feces and feed in the water body are precipitated to the bottom side of the breeding water tank 1, the fish feces and feed precipitates can enter the sedimentation tank 401 through the holes on the top of the filter plate 402, and the fish feces and feed precipitates can slowly gather and concentrate through the arc-shaped bottom wall in the sedimentation tank 401, and after concentration, the fish feces and feed precipitates are sucked into the purification ditch by the external pump body to the suction pipe 8, or directly by opening the valve of the suction pipe 8, and sewage is discharged by gravity of the water body, which is beneficial to divide the fish living space and the feces precipitation space through the setting of the sedimentation tank 401, so as to avoid the fermentation of feces in the breeding water tank 1 affecting the biological activity of the farmed fish.

[0055] A filter plate 402 is connected to the top of the sedimentation tank 401. A plurality of filter holes are provided on the top of the filter plate 402. A sweeping plate 405 is rotatably connected to the top of the filter plate 402. The sweeping plate 405 is connected to a driving unit 409 through a rod body. One side of the driving unit 409 is connected to the top of the sedimentation tank 401 through a support plate 404.

[0056] A plurality of grooves are arranged in an array on one side of the sweeping plate 405, and a moving rod 407 is slidably connected to the inner cavity of the groove, and 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, and both ends of the spring piece 408 are respectively connected to corresponding positions on both sides of the top of the sweeping plate 405;

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

[0058] A cover 5 may be provided on the top of the aquaculture water tank 1, and the cover 5 is connected to the top of the aquaculture water tank 1 by snap fastening, and a plurality of legs 7 are connected to the periphery of the bottom of the aquaculture water tank 1. When necessary, the aquaculture tank 1 can be closed for breeding, such as in winter when it is cold, so that the breeding temperature can be relatively increased. Or some shrimps do not like light, so the light intensity of the aquaculture tank can be controlled by covering the cover and appropriately adjusting the cover material, such as light transmittance.

[0059] Specifically: through the designed sweeping plate 405, when part of the fish feces impurities are accumulated at the position where no hole is formed on the top of the filter plate 402, the driving part 409 can be used to drive the bottom rod body to rotate, and the rotation of the rod body can drive the sweeping plate 405 to rotate on the top of the filter plate 402, and the accumulated fish feces impurities can be swept into the holes of the filter plate 402 by the rotating sweeping plate 405, thereby improving the stability of the internal space of the aquaculture water tank 1 by reducing the accumulation of fish feces on the top of the filter plate 402, and through the designed sweeping plate 405, the sweeping plate 405 can be rotated in the slide rail groove 403 through the pulleys 410 on both sides, which is conducive to improving the moving stability of the sweeping plate 405, and avoiding the axial runout of the sweeping plate 405 caused by the interference of the accumulation of fish feces impurities, which affects the scraping effect;

[0060] Furthermore, through the designed sweeping block 406 and spring sheet 408, when the sweeping plate 405 moves to contact the hard feed, the sweeping block 406 can be forced to move upward through the moving rod 407 to avoid damage to the filter plate 402 due to excessive squeezing. At the same time, through the designed spring sheet 408, when the moving rod 407 moves, the spring sheet 408 can be squeezed, and the spring sheet 408 can use its own elastic force to keep the bottom sweeping block 406 fully fitted with the filter plate, which is beneficial to improve the scraping and sweeping effect. The driving part 409 can be a driving motor that drives the rod body to rotate.

[0061] Working principle: When in use, when the densely-raised fish in the aquaculture water tank 1 produce food residues and feces through feeding, the food residues and feces are precipitated into the bottom filtering mechanism by themselves, and the food residues and feces are sent to the purification ditch by suction through the suction pipe 8 or by water pressure self-drainage. Part of the feces and food residues sent to the purification ditch can be used as food for aquaculture organisms such as loaches or crabs, so that the fish feces and a small amount of feed are removed through the purification ditch, and the initially purified water body enters the rice field on one side for secondary purification, so as to realize full utilization of aquaculture tail water and achieve zero discharge;

[0062] When oxygen is supplemented in the aquaculture water tank 1, the delivery pipe 204 is delivered to the oxygen delivery tank 202 through the pumping equipment. The multiple sample delivery ring tubes connected to the peripheral side of the oxygen delivery tank 202 deliver the oxygen to the aquaculture water tank 1 evenly through the multiple annular oxygen delivery nozzles 203. The oxygen delivered to the aquaculture water tank 1 first contacts 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 and the delivered oxygen are fully mixed and then delivered to the aquaculture water tank 1. When the fish swim in the aquaculture water tank 1, when the swimming fish contacts the force plate 304, the force plate 304 rotates outside the slide bar 308 through the rotating sleeve 303. The rotating rotating sleeve 303 drives the fixed frame 305 to rotate and pushes the guide cover 301 on one side to partially deflect, thereby disturbing the vibration in the water body.

[0063] When the fish feces and feed in the water body settle to the bottom side of the aquaculture water tank 1, the fish feces and feed sediments enter the sedimentation tank 401 through the holes on the top of the filter plate 402, and the fish feces and feed sediments slowly gather and concentrate through the arc-shaped bottom wall in the sedimentation tank 401. After being concentrated, the fish feces and feed sediments are discharged to the suction pipe 8 through the external pump body and then pumped out to the purification ditch;

[0064] When some fish feces impurities are accumulated at a position where no hole is formed on the top of the filter plate 402, the driving unit 409 drives the bottom rod body to rotate, and the rotation of the rod body drives the sweeping plate 405 to rotate on the top of the filter plate 402, and the accumulated fish feces impurities are swept into the holes of the filter plate 402 by the rotating sweeping plate 405. When the sweeping plate 405 moves and contacts the hard feed, the sweeping block 406 is forced to move upward through the moving rod 407 to avoid damage to the filter plate 402 caused by excessive squeezing. At the same time, through the designed spring piece 408, when the moving rod 407 moves, the spring piece 408 is squeezed, and the spring piece 408 uses its own elastic force to keep the bottom sweeping block 406 fully fitted with the filter plate.
