Description

Technical Field

[0001] This utility model relates to the field of bass farming technology, specifically to a multi-stage ecological filtration system for bass farming wastewater. Background Technology

[0002] Sea bass are a type of carnivorous fish widely distributed in temperate and tropical waters. They belong to the order Perciformes and include many species, including both sea bass and freshwater sea bass. Their flesh is delicious and nutritious, so sea bass farming has high economic value.

[0003] In bass farming, it is necessary to continuously filter wastewater in fish ponds to reduce suspended debris. Currently, the common practice is to let the wastewater flow directly into a pool with brushes. However, the debris in the wastewater cannot fully contact the brushes, resulting in inadequate filtration. Therefore, there is an urgent need to design a multi-stage ecological filtration system for bass farming wastewater to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage ecological filtration system for sea bass farming wastewater to address the aforementioned shortcomings in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-stage ecological filtration system for bass farming wastewater includes a pool. Inside the pool, there are sequentially arranged barrier zones, a filtration zone on one side of the barrier zone, a sterilization zone on the side of the filtration zone away from the barrier zone, and a dosing zone on the side of the sterilization zone away from the filtration zone. The filtration zone contains evenly distributed brushes. Two horizontal pipes, Horizontal Pipe 1 and Horizontal Pipe 2, are fixed inside the filtration zone. The top outer wall of Horizontal Pipe 1 has evenly distributed outlets, and the top outer wall of Horizontal Pipe 2 is welded with evenly distributed vertical pipes. One end of Horizontal Pipe 1 connects to the barrier zone, and one end of Horizontal Pipe 2 connects to the sterilization zone. The brushes are located between the outlets and the vertical pipes.

[0007] Furthermore, a bracket is fixed to the side wall of the filtration zone, and a second crossbar is provided inside the bracket, with the brush fixed to the bottom of the second crossbar.

[0008] Furthermore, the top of the sterilization zone is covered with a cover plate, and an ultraviolet lamp is installed at the bottom of the cover plate.

[0009] Furthermore, an inlet pipe is provided on the side of the barrier zone away from the filtration zone, and a water pump is installed inside the dosing zone.

[0010] Furthermore, a net basket is installed inside the barrier area, a horizontal bar is fixed to the top of the barrier area, and a suspension rope is fixed between the horizontal bar and the net basket.

[0011] Furthermore, a mesh basket two is provided inside the dosing zone, and a horizontal pipe three is provided between the dosing zone and the sterilization zone, with the horizontal pipe three located on one side of the mesh basket two.

[0012] In the above technical solution, the multi-stage ecological filtration system for bass farming wastewater provided by this utility model has the following beneficial effects: By setting a brush between the outlet and the vertical pipe, the water flowing from the outlet can effectively pass through the brush and enter the interior of the vertical pipe. The staggered flow between the outlet and the vertical pipe ensures that impurities in the bass farming wastewater are fully filtered, resulting in a cleaner filtration effect. A net basket is placed in the barrier zone, which, on the one hand, works with the filtration zone to achieve a multi-stage filtration effect, and on the other hand, the crossbar and hanging rope allow the net basket to be easily pulled out of the barrier zone, making it easy to clean the impurities trapped inside. Ultraviolet lamps can sterilize the filtered water, further reducing pathogens. The net basket in the dosing zone can be filled with probiotics or antibacterial drugs, effectively ensuring the bass farming water reaches a healthy state. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1As shown in the figure, the multi-stage ecological filtration system for sea bass farming wastewater provided in this embodiment of the present invention includes a pool 1. A barrier zone 2 is arranged sequentially inside the pool 1. A filtration zone 3 is arranged on one side of the barrier zone 2. A sterilization zone 4 is arranged on the side of the filtration zone 3 away from the barrier zone 2. A dosing zone 5 is arranged on the side of the sterilization zone 4 away from the filtration zone 3. A uniformly distributed brush 11 is arranged inside the filtration zone 3. A horizontal pipe 13 and a horizontal pipe 2 15 are fixed inside the filtration zone 3. A uniformly distributed outlet 14 is arranged on the top outer wall of the horizontal pipe 13. A uniformly distributed vertical pipe 16 is welded to the top outer wall of the horizontal pipe 2 15. One end of the horizontal pipe 13 is connected to the barrier zone 2, and one end of the horizontal pipe 2 15 is connected to the sterilization zone 4. The brush 11 is located between the outlet 14 and the vertical pipe 16.

[0019] Specifically, in this embodiment, a water tank 1 is included. Inside the water tank 1, a barrier zone 2 is sequentially arranged. A filtration zone 3 is arranged on one side of the barrier zone 2. A sterilization zone 4 is arranged on the side of the filtration zone 3 away from the barrier zone 2. A dosing zone 5 is arranged on the side of the sterilization zone 4 away from the filtration zone 3. This allows wastewater to first enter the barrier zone 2 for initial blocking of large particles, then enter the filtration zone 3 for filtration, and finally enter the sterilization zone 4 for sterilization. Finally, chemicals are added in the dosing zone 5 before discharge, ensuring thorough purification of the water. The filtration zone 3 is equipped with evenly distributed brushes 11. The brushes 11 intercept suspended solids in the water, such as feed residue and fish excrement, through their dense bristle structure. Horizontal pipes 13 and 15 are fixed inside the filtration zone 3. Evenly distributed outlets 14 are arranged on the top outer wall of horizontal pipe 13. The outlets 14 are located within the filter... In the lower area of ​​zone 3, the top outer wall of the second horizontal pipe 15 is welded with evenly distributed vertical pipes 16. The opening above the vertical pipe 16 is located in the upper area of ​​the filtration zone 3, so that the outlet 14 and the vertical pipe 16 form a staggered effect, increasing the length of the water flow path. One end of the first horizontal pipe 13 is connected to the barrier zone 2, and the end of the first horizontal pipe 13 away from the barrier zone 2 is closed. One end of the second horizontal pipe 15 is connected to the sterilization zone 4, and the end of the second horizontal pipe 15 away from the sterilization zone 4 is also closed. The brush 11 is located between the outlet 14 and the vertical pipe 16, so that the water flowing out of the outlet 14 can fully pass through the brush 11 and enter the interior of the vertical pipe 16. When in use, the water level in the fish pond is slightly lower than the upper edge of the pond 1, and the liquid levels inside the barrier zone 2, filtration zone 3, sterilization zone 4 and dosing zone 5 of the pond 1 tend to be level with the pond liquid surface due to the principle of communicating vessels.

[0020] The multi-stage ecological filtration system for sea bass farming wastewater provided by this utility model uses brushes 11 positioned between the outlet 14 and the vertical pipe 16. This allows the water flowing out of the outlet 14 to effectively pass through the brushes 11 and enter the interior of the vertical pipe 16. The water then flows through the outlet 14 and the vertical pipe 16 at different heights, ensuring that impurities in the wastewater can fully contact the brushes 11. This allows for thorough filtration of impurities in the sea bass farming wastewater, resulting in a cleaner filtration effect.

[0021] In another embodiment of this utility model, a bracket 12 is fixed to the side wall of the filtration zone 3, and a crossbar 10 is provided inside the bracket 12. A brush 11 is fixed to the bottom of the crossbar 10, and the crossbar 10 can be easily removed from the bracket 12, making it easy to remove and rinse the brush 11. The top of the sterilization zone 4 is covered with a cover plate 20, which does not form a sealed cover for the sterilization zone 4. An ultraviolet lamp 21 is installed at the bottom of the cover plate 20, which can sterilize the filtered water and further reduce the pathogens in the water. An inlet pipe 9 is provided on the side of the barrier zone 2 away from the filtration zone 3. A water pump 18 is installed inside the dosing zone 5, which uses the water pump 18 to re-transport the filtered water into the fish pond. The dosing zone 5 is provided with a water inlet pipe 9. A horizontal pipe 17 is installed between the dosing zone 5 and the sterilization zone 4 in the second net basket 19. The horizontal pipe 17 is located on one side of the second net basket 19. The second net basket 19 inside the dosing zone 5 can be filled with probiotics or antibacterial drugs, which can effectively bring the water in the sea bass farming area to a healthy state. A net basket 7 is installed inside the barrier zone 2. A horizontal bar 6 is fixed to the top of the barrier zone 2. A hanging rope 8 is fixed between the horizontal bar 6 and the net basket 7. The horizontal bar 6 can be removed from the top of the barrier zone 2 and placed inside the barrier zone 2 through the net basket 7. On the one hand, it can work with the filter zone 3 to achieve a multi-stage filtration effect. On the other hand, the horizontal bar 6 and the hanging rope 8 can easily pull the net basket 7 out of the barrier zone 2, so that the debris trapped inside the barrier zone 2 can be easily cleaned.

[0022] Working principle: During use, the wastewater from sea bass farming enters the barrier zone 2 through the inlet pipe 9, and larger suspended debris in the water is blocked by the mesh basket 7. Then, the water enters the horizontal pipe 13 and flows into the filtration zone 3 through the outlet 14. After passing through the brush 11, the water enters the vertical pipe 16. The brush 11 can filter out small feed residues and sea bass excrement in the water. After entering the vertical pipe 16, the water enters the sterilization zone 4 through the horizontal pipe 25. The water is further sterilized by the ultraviolet lamp 21 inside the sterilization zone 4. Then, the water flows into the medicine addition zone 5 through the horizontal pipe 37. The water can be discharged into the fish pond by the water pump 18. The mesh basket 29 inside the medicine addition zone 5 can be filled with probiotics or antibacterial drugs, so that the water flowing out of the horizontal pipe 317 can flush the drugs, allowing the drugs to gradually dissolve in the water.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
