Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a water purification device for aquaculture. Background Art

[0002] In the aquaculture industry, water purification plays a vital role, which is directly related to the health of the aquaculture environment, the healthy growth of aquatic organisms and the ultimate increase in production. However, the aquaculture process will inevitably produce the accumulation of feces and leftover bait, which not only leads to eutrophication of water bodies, but also causes the concentration of harmful substances such as ammonia nitrogen and nitrite to rise sharply, seriously threatening the health of aquaculture organisms, and may even cause disease outbreaks, ultimately leading to significant losses in the aquaculture industry.

[0003] Currently, the main strategy for water purification is to rely on mechanical equipment for cleaning. Although mechanical cleaning significantly improves work efficiency, the mechanical parts often squeeze and rub the bottom of the aquaculture pond during the cleaning process, which will break down the feces and leftover bait at the bottom into tiny particles suspended in the water, increasing the risk of these harmful substances being ingested by farmed organisms. Once weaker organisms inhale these harmful particles, they are very likely to develop diseases. Once the induced diseases are contagious, the rapid spread of these diseases is more likely to cause a devastating blow to the entire aquaculture pond, causing immeasurable economic losses to farmers.

[0025] Please refer to the attached Figure 1 The present application provides a water purification device for aquaculture, comprising a pumping device 1, a physical filter pool 2, an ecological filter pool 3 and a biochemical filter pool 4, wherein the pumping device 1 comprises a water pump 5, a pumping pipe 6, a pumping bypass 7, a water outlet pipe 8, a covering film 9, a runner 10, a guide rail 11 and a water spray pipe 12, wherein the covering film 9 is an annular structure whose width matches that of the aquaculture pool, a water spray pipe 12 and a runner 10 are arranged at the bottom of the covering film 9, the runner 10 is provided with a plurality of water inlets 13, the guide rail 11 is arranged on the side wall of the aquaculture pool, the runner 10 rolls along the guide rail 11, and the runner 10 is connected to the pumping bypass 7 and the pumping pipe 12 through the pumping bypass 7. 6 is connected, preferably, the impeller 10 is connected with the pumping bypass 7 through a rotating joint, the pumping pipe 6 is connected with the water pump 5, the water pump 5 is connected with the physical filtration pool 2 through the outlet pipe 8, the physical filtration pool 2, the ecological filtration pool 3 and the biochemical filtration pool 4 are connected in sequence, the biochemical filtration pool 4 is provided with a return pipe 33 and a return bypass pipe 34, the return pipe 33 and the return bypass pipe 34 are connected with the breeding pond, the outlet of the return pipe 33 is arranged in the area surrounded by the covering film 9, the return bypass is connected with the spray pipe 12, and the outlet of the spray pipe 12 is arranged on both sides of the impeller 10 below the covering film 9.

[0026] Water is pumped from the culture pond by a water pump 5 through a water pumping pipe 6 and a water pumping bypass 7. The water inlet 13 of the water pumping pipe 6 is directly placed in the culture pond, and is responsible for pumping most of the water into the physical filtration pool 2. At the same time, the water pumping bypass 7 is connected to the runner 10 at the bottom of the covering film 9. As the runner 10 rotates, the water inlet 13 thereon continuously pumps away the water under the covering film 9 and impurities such as excrement that may be deposited. The covering film 9 is designed as an annular structure with a width that matches the culture pond and is laid at the bottom of the culture pond. The runner 10 is installed at the bottom of the covering film 9 and rolls along the guide rail 11 on the side wall of the culture pond. The rotation of the runner 10 not only drives the covering film 9 to move backward, but also effectively extracts and takes away impurities such as leftover bait and feces under the covering film 9 through its water inlet 13.

[0027] The water extracted through the pumping pipe 6 and the pumping bypass 7 first enters the physical filtration tank 2. Here, large particles of impurities in the water are removed through physical screens or sedimentation tanks to achieve preliminary purification. The physically filtered water then enters the ecological filtration tank 3. Aquatic plants are planted in the tank, and microbial communities are introduced. Aquatic plants release oxygen by absorbing nutrients and photosynthesis, while microorganisms further decompose organic matter in the water, reduce the content of harmful substances such as ammonia nitrogen and nitrite, and improve the water quality environment. The biochemical filtration tank 4 is filled with high-efficiency biological fillers. Microorganisms grow on these fillers and convert harmful substances in the water into harmless or low-toxic substances through biochemical reactions, thereby achieving comprehensive purification of the water.

[0028] The biochemical filtration pool 4 is provided with a return pipe 33 and a return bypass pipe 34 to return the purified water to the culture pool. The outlet of the return pipe 33 is located in the area surrounded by the covering film 9, so that the clean water can enter the culture pool and push the covering film 9 to adhere to the bottom of the pool and stretch forward and backward. The return bypass pipe 34 directly sends the water to the bottom of the covering film 9, impacting the bottom of the pool to make impurities such as feces float up, enter the runner 10 with the water flow and be pumped away.

[0029] During the entire process of pumping and purifying water, the covering film 9 always covers the bottom of the breeding pond, effectively preventing impurities such as feces in the pumped area from polluting the surrounding water during movement. Its annular design ensures that a large area of ​​bottom feces can be pumped out in one movement. The covering film 9 covers the bottom of the breeding pond under the impact of the water flow. The covering film 9 can cover the bottom of the pond softly and can also cover the uneven areas of the bottom of the pond well. During the movement of the covering film 9, the water flow continuously pushes the front covering film 9 to cover the front, and at the same time pulls up the rear covering film 9. Therefore, during the movement of the covering film 9, there is almost no horizontal friction on the bottom of the pond, which can prevent the feces at the contact end from being lifted or crushed, and reduce the suspended particles in the breeding pond.

[0030] Specifically, the water return bypass is provided with an arc plate 14, and the upper end of the arc plate 14 is in contact with the side of the rotor 10. When the rotor 10 rotates, the arc plate 14 separates the covering film 9 from the rotor 10. During the separation process, the covering film 9 does not move horizontally with the bottom of the breeding pond, thereby preventing the feces at the bottom of the breeding pond from being crushed.

[0031] Specifically, a rotating shaft 15 is provided on the side of the rotating wheel 10, and the rotating shaft 15 is installed on a bracket 16. The upper end of the bracket 16 is higher than the water surface. The rotating shaft 15 is provided with a gear 17. The diameter of the gear 17 is the same as the diameter of the rotating wheel 10. The guide rail 11 is provided with a rack 18, and the rack 18 is meshed with the gear 17. By moving the bracket 16, the gear 17 is driven to rotate, thereby driving the rotating wheel 10 to rotate. The diameter of the gear 17 is the same as the diameter of the rotating wheel 10. The guide rail 11 is provided with a rack 18, and the rack 18 is meshed with the gear 17. When moving, the linear speed of the rotating wheel 10 is equal to the translation speed, so as to prevent the covering film 9 from horizontally offset.

[0032] Specifically, the upper end of the bracket 16 is in an inverted U shape, and the bracket 16 is slidably connected to the horizontal rod 19. The horizontal rod 19 is provided with a pull rope 20 for driving the bracket 16 to move, and the pull rope 20 is connected to the reeling mechanism. The bracket 16 slides along the horizontal rod 19, so that the sliding of the bracket 16 is more stable. The pull rope 20 is provided on the horizontal rod 19, and the pull rope 20 is reeled in by the reeling mechanism, thereby pulling the bracket 16 to move. The reeling mechanism drives the direct movement at a distance, so as to suck away the feces at the bottom of the breeding pond.

[0033] Specifically, the reeling mechanism includes a motor 21, a first reel 22, a second reel 23 and a fixed pulley 24. The output shaft of the motor 21 is connected to the first reel 22 and the second reel 23. The bracket 16 is connected to the first reel 22 through one of the pull ropes 20. The bracket 16 is connected to the second reel 23 after another pull rope 20 passes around the fixed pulley 24. When the first reel 22 reels the pull rope 20, the second reel 23 releases the other pull rope 20. When the motor 21 rotates forward, it drives the first reel 22 to pull the first pull rope 20 to reel, and drives the second pull rope 20 on the second reel 23 to release, thereby driving the bracket 16 to move forward. When the motor 21 rotates reversely, it drives the first reel 22 to release the first pull rope 20, and drives the second reel 23 to reel the second pull rope 20, thereby driving the bracket 16 to move backward. It can drive the bracket 16 to move back and forth at a uniform speed, so as to suck away the feces at the bottom of the breeding pond.

[0034] Specifically, the physical filter pool 2 is provided with several layers of filter screens 25, the filter screens 25 are fixed in a support frame 26, the support frame 26 is provided with support legs 27, and the filter screens 25 are arranged in sequence from top to bottom, and the aperture of the filter screen 25 located at the top is larger than the aperture of the filter screen 25 located at the bottom. When feces pass through the filter screen 25, large particles are intercepted in the upper layer, and small particles are also intercepted after entering the filter screen 25 at the lower layer, which can effectively reduce the feces in the water body and reduce the processing pressure of the ecological filter pool 3 and the biochemical filter pool 4. The staff cleans the filter screen 25 after a period of time and disposes of the particles intercepted on the filter screen 25.

[0035] Specifically, the ecological filter pool 3 is provided with water purification plants 28, and the water purification plants 28 are planted on a floating frame 29. The floating frame 29 is provided in the ecological filter pool 3, and the water purification plants 28 are planted on the floating frame 29, and the water purification plants 28 are used to purify the water body.

[0036] Specifically, the biochemical filtration pool 4 is provided with a bacterial culture filter material, which includes one or more of volcanic rocks 30, quartz balls 31 or bacterial houses 32. The porous structure of the bacterial culture filter material can attach nitrifying bacteria, and the nitrifying bacteria are used to decompose harmful substances such as ammonia nitrogen in the water.

[0037] Specifically, the bacterial culture filter material includes volcanic rocks 30, quartz balls 31 and bacterial houses 32, which are arranged from bottom to top. A variety of bacterial culture filter materials are used together and arranged in sequence from top to bottom, thereby improving the filtering effect.

[0038] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
