Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically, to an aquaculture ecological cycle purification system. Background Art

[0002] An aquaculture ecological cycle purification system is a comprehensive system integrating aquaculture and water purification, aiming to achieve efficient utilization of water resources and continuous purification of water quality by mimicking the material cycle and energy flow in natural ecosystems.

[0003] In the prior art, when the existing pond aquaculture cycle purification system is in use, the wastewater needs to be precipitated in the sedimentation tank, usually with a barrier net to filter impurities and block fish at the same time. However, during the filtration process, the barrier net may be blocked by impurities, resulting in a poor screening effect of the barrier net and affecting the purification effect of the entire system. How to invent an aquaculture ecological cycle purification system to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an aquaculture ecological cycle purification system, aiming to improve the problem that when the existing pond aquaculture cycle purification system is in use, the barrier net may be blocked by impurities during filtration, resulting in a poor screening effect of the barrier net and affecting the purification effect of the entire system.

[0005] The utility model is implemented as follows:

[0006] The utility model provides an aquaculture ecological cycle purification system, which includes an aquaculture area, a sedimentation area and a purification area arranged on one side of the aquaculture area. A barrier net is installed between the aquaculture area and the sedimentation area. A pressure pump is installed on the outer wall of one side of the aquaculture area. The output end of the pressure pump is installed with a water outlet pipe. One end of the water outlet pipe is installed with a shunt pipe, and one end of the shunt pipe is installed with a plurality of diversion pipes;

[0007] A slope is provided on the sedimentation area, symmetric landslides are provided on the slope, and sieve holes are provided at the barrier between the sedimentation area and the purification area;

[0008] An installation frame is provided on the inner wall of the purification area. An ecological floating island is installed on the installation frame. A filter screen is installed on the inner wall of the purification area. One end of the inner wall of the purification area is installed with a water inlet pipe fixedly connected to the input end of the pressure pump.

[0009] Preferably, the aperture of the barrier net is larger than the aperture of the sieve holes, and the aperture of the sieve holes is larger than the aperture of the filter screen.

[0010] Preferably, the installation frame is fixedly connected to the inner wall of the purification area. The water level in the purification area is higher than the installation frame, and the ecological floating island floats on the water surface above the installation frame.

[0011] By adopting the above technical scheme, the granular impurities in the breeding area and the feed particles that have sunk to the bottom enter the sedimentation area through the blocking net, and are accumulated on the inner wall of one side of the sedimentation area through the slope and landslide under the action of the water flow. The water body is then further filtered through the sieve holes and enters the purification area. The ecological floating island absorbs the excess nitrogen and phosphorus elements in the water body to reduce the eutrophication of the water body. At the same time, the oxygen content in the water is increased through photosynthesis, and the water body is further filtered through the filter screen. Finally, the purified water body is discharged into the breeding area through the diversion pipe by a pressure pump for recycling, thereby reducing the frequency of water replacement.

[0012] Preferably, the inner wall of the upper end of the blocking net is rotatably connected to a fixed shaft, and both ends of the fixed shaft are fixedly connected to the inner wall of the breeding area.

[0013] Preferably, two symmetrical notches are provided at the lower end of the blocking net, and baffles are fixedly connected to the inner walls of the notches.

[0014] Preferably, the inner wall of one side of the sedimentation zone close to the bottom end of the screen is rotatably connected to a rotating shaft, the outer wall of the rotating shaft close to the slot is fixedly connected to a rotating blade, and one end of the rotating blade is slidably connected to the outer wall of the baffle.

[0015] Preferably, one end of the diversion pipe is fixedly connected to a spray pipe, a nozzle is installed on the inner wall of the upper end of the spray pipe, both ends of the diversion pipe are installed with drive pipes aligned with the rotating blades, and the outer wall of the drive pipe is installed with a fixed frame fixedly connected to the bottom of the breeding area.

[0016] By adopting the above technical scheme, in the process of circulating the water body, the pressure pump cooperates with the driving pipe to make the high-speed water flow act on the rotating blades to make them rotate, and the swing of the net is realized by cooperating with the baffle in the groove at the lower end of the net. In the process of the net recovery, the holes are given an opposite force to flush out the impurities blocked inside to avoid clogging of the net. At the same time, the ejection pipe arranged on the diversion pipe cooperates with the nozzle to spray part of the water to the surroundings and then let it fall back into the breeding area, so as to increase the contact area with the air and then increase the oxygen content of the water.

[0017] The beneficial effects of the utility model are:

[0018] By means of the ecological floating islands arranged on the purification pond, the surplus nitrogen and phosphorus elements in the water body are absorbed, while reducing the eutrophication of the water body, promoting the growth of the ecological floating islands, improving the photosynthesis effect, and increasing the oxygen content in the water body. At the same time, the spray pipes protruding out of the water surface cooperate with the spray nozzles to spray the water body into the air, increasing the contact area with the air, enabling the water body to fully absorb the oxygen in the air, further increasing the oxygen content in the water body, improving the survival rate of fish, and the arranged driving pipes cooperate with the baffles at the lower end of the barrier net to realize the swing of the barrier net, so that the water flow gives an opposite force to the holes to flush out the impurities blocking the holes of the barrier net to prevent the barrier net from being blocked, thereby maintaining the screening effect of the barrier net and improving the purification effect of the entire system.

Detailed Embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Example, refer to Figures 1 - 5 , an aquaculture ecological cycle purification system, including an aquaculture area 1, a sedimentation area 3 arranged on one side of the aquaculture area 1, and a purification area 6. A retaining net 2 is installed between the aquaculture area 1 and the aquaculture area 1. A pressure pump 11 is installed on the outer wall of one side of the aquaculture area 1. The output end of the pressure pump 11 is installed with a water outlet pipe 13. One end of the water outlet pipe 13 is installed with a shunt pipe 14. One end of the shunt pipe 14 is installed with a plurality of diversion pipes 17;

[0028] A slope 4 is provided on the sedimentation area 3. Symmetrical landslides 5 are provided on the slope 4. Sieve holes 7 are provided at the barrier between the sedimentation area 3 and the purification area 6;

[0029] An installation frame 8 is provided on the inner wall of the purification area 6. An ecological floating island 9 is installed on the installation frame 8. A filter screen 10 is installed on the inner wall of the purification area 6. One end of the inner wall of the purification area 6 is installed with a water inlet pipe 12 fixedly connected to the input end of the pressure pump 11.

[0030] Furthermore; the aperture of the retaining net 2 is larger than the aperture of the sieve holes 7, and the aperture of the sieve holes 7 is larger than the aperture of the filter screen 10. The installation frame 8 is fixedly connected to the inner wall of the purification area 6. The water level in the purification area 6 is higher than the installation frame 8. The ecological floating island 9 floats on the water surface above the installation frame 8.

[0031] It should be noted that: the particulate impurities and the sedimented feed particles in the aquaculture area 1 are pushed by the diversion pipes 17 to enter the sedimentation area 3 through the retaining net 2, and are accumulated on one side inner wall of the sedimentation area 3 through the slope 4 and the landslides 5 under the action of water flow and gravity. Then, the impurities in the water body are further filtered through the sieve holes 7 and enter the purification area 6. The ecological floating island 9 absorbs the surplus nitrogen and phosphorus elements in the water body to reduce the eutrophication of the water body. At the same time, the oxygen content in the water is increased through photosynthesis. At the same time, the installation frame 8 arranged below the ecological floating island 9 limits it to prevent it from being overturned under the action of water flow. Then, the water body is further filtered through the filter screen 10, and then the purified water body is discharged into the aquaculture area 1 through the diversion pipes 17 by the pressure pump 11 for recycling, reducing the frequency of water body replacement.

[0032] Further, the inner wall of the upper end of the netting 2 is rotatably connected to a fixed shaft 24, and both ends of the fixed shaft 24 are fixedly connected to the inner wall of the breeding area 1. Two symmetrical notches 20 are formed at the lower end of the netting 2, and a baffle 21 is fixedly connected to the inner wall of the notch 20. One side inner wall of the sedimentation area 3 close to the bottom end of the netting 2 is rotatably connected to a rotating shaft 22. A rotating blade 23 is fixedly connected to the outer wall of the rotating shaft 22 close to the notch 20. One end of the rotating blade 23 is slidably connected to the outer wall of the baffle 21. One end of the shunt pipe 14 is fixedly connected to a spraying pipe 15, and a nozzle 16 is installed on the inner wall of the upper end of the spraying pipe 15. Driving pipes 18 are installed at both ends of the shunt pipe 14 and are aligned with the rotating blade 23. A fixed frame 19 fixedly connected to the bottom of the breeding area 1 is installed on the outer wall of the driving pipe 18.

[0033] It should be noted that during the process of circulating the water body, the pressure pump 11 cooperates with the driving pipe 18 to make the high-speed water flow act on the rotating blade 23 to make it rotate. One end of the rotating blade 23 abuts against and slides on the outer wall of the baffle 21 in the notch 20 at the lower end of the netting 2. At the same time, the baffle 21 drives the netting 2 to rotate slightly, and returns when the rotating blade 23 and the baffle 21 are separated from contact, so that the netting 2 keeps swinging, and the direction of the netting 2 during the return process is opposite to the direction of the water flow, so that the water flow gives an opposite force to the holes to flush out the impurities blocking the holes of the netting 2 to avoid blockage of the netting 2, thereby maintaining the screening effect. At the same time, one end of the spraying pipe 15 provided on the shunt pipe 14 extends out of the water body, and the nozzle 16 is used to spray part of the water body around the spraying pipe 15 and then fall back into the breeding area 1, so as to increase the contact area between the water body and the air, and further enable the water body to fully absorb the oxygen in the air, and further increase the oxygen content of the water body in the breeding area 1.

[0034] The working principle of this aquaculture ecological circulation purification system:

[0035] Start the pressure pump 11 to control the direction of the water flow ejected from the diversion pipe 17. The particulate impurities and the sedimented feed particles in the aquaculture area 1 are pushed by the diversion pipe 17 to pass through the barrier net 2 and enter the sedimentation area 3. The sieved impurities are stacked on one inner wall of the sedimentation area 3 through the slope 4 and the landslide 5 under the action of water flow and gravity. Then, the impurities in the water body are further filtered through the sieve holes 7 and enter the purification area 6. The ecological floating island 9 absorbs the surplus nitrogen and phosphorus elements in the water body to reduce the eutrophication of the water body. At the same time, the oxygen content in the water is increased through photosynthesis. The mounting frame 8 arranged below the ecological floating island 9 limits it to prevent it from being overturned by the water flow. Then, the water body is further filtered through the filter screen 10, and then the purified water body is discharged into the aquaculture area 1 through the diversion pipe 17 by the pressure pump 11 for recycling, reducing the frequency of water body replacement. At the same time, the pressure pump 11 cooperates with the drive pipe 18 to make the high-speed water flow act on the rotating blades 23 to make them rotate. One end of the rotating blade 23 abuts against the outer wall of the baffle 21 in the notch 20 at the lower end of the barrier net 2 and slides. At the same time, the baffle 21 drives the barrier net 2 to rotate slightly, and returns when the rotating blade 23 and the baffle 21 are separated from contact, so that the barrier net 2 swings continuously, and in the process of the return of the barrier net 2, it is opposite to the direction of the water flow, so that the water flow gives an opposite force to the holes to flush out the impurities blocking the holes of the barrier net 2 to prevent the barrier net 2 from being blocked. At the same time, one end of the spray pipe 15 arranged on the shunt pipe 14 extends out of the water body, and cooperates with the spray head 16 to spray part of the water body around the spray pipe 15 and then fall back into the aquaculture area 1, so as to increase the contact area between the water body and the air, and further enable the water body to fully absorb the oxygen in the air, and further increase the oxygen content of the water body in the aquaculture area 1.

[0036] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0037] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
