Description

Technical Field

[0001] The invention relates to the field of aquaculture water purification, and in particular to a water filtering and circulating purification device for improving the quality of aquacultured seabass. Background Art

[0002] As a highly economically valuable farmed fish, seabass's growth environment directly impacts its quality, survival rate, and market competitiveness. High-density farming conditions lead to the accumulation of fish metabolites, leftover bait, suspended particles, and microorganisms in the water, causing changes in the water's physical, chemical, and biological properties, such as turbidity, elevated ammonia nitrogen concentrations, and insufficient dissolved oxygen. These issues not only affect seabass' growth rate but also weaken their immunity, increasing their risk of disease.

[0003] Currently, common water purification methods in aquaculture rely primarily on a combination of physical filtration, biodegradation, and regular water changes to improve water quality. Traditional physical filtration devices typically use single-layer filters or sedimentation tanks to remove larger suspended impurities, while biological filtration uses nitrifying bacteria to break down harmful substances such as ammonia nitrogen and nitrite in the water, reducing toxicity to fish. Furthermore, regular water changes are widely used to dilute pollutants in the water and maintain stable water quality. While these technologies can improve the water environment to a certain extent, they still have many technical limitations and cannot meet the needs of modern aquaculture for efficient, energy-saving, and intelligent water quality management.

[0004] First, water quality monitoring mainly relies on manual detection, which results in delayed adjustment and low accuracy, making it difficult to respond to water quality changes in a timely manner and easily causing water quality deterioration. Second, the single-layer filtration method has limited effect on removing impurities of different particle sizes, which can easily lead to filter blockage, affecting the smooth flow of water and reducing purification efficiency. In addition, the high frequency of water changes leads to waste of water resources, increased energy consumption and operating costs, and traditional chemical disinfection methods may destroy the ecological balance of the water body and affect the healthy growth of sea bass. Therefore, a water filtration and circulation purification device that improves the quality of farmed sea bass is proposed to solve the above problems. Summary of the Invention

[0045] Please see the attached Figure 11 , the central control system includes:

[0046] Monitoring module: This module receives water quality data collected by pH sensor 9, turbidity sensor 10, ammonia nitrogen sensor 11 and dissolved oxygen sensor 12 in real time and transmits it to the central control system for processing;

[0047] Analysis module: The analysis module uses the data processing unit to analyze the data collected by the monitoring module, determine whether the water quality meets the standards, and automatically adjust the operating status of related equipment based on the analysis results.

[0048] Working principle: First, the water to be purified is first drawn from an external source by a water pump, and the water flows through the water inlet of the coarse filter mechanism 6 for preliminary filtration. The filter box 601 in the coarse filter mechanism 6 is equipped with a stainless steel mesh box 603 and multiple clamping bars 604. These clamping bars 604 support filter plates 602 with gradually smaller diameters. The water passes through these filter plates to remove larger impurities, ensuring that the water is preliminarily cleaned before entering the next purification stage;

[0049] After the coarse filtration, the water flows through the water pump 2 7 and enters the middle filtration mechanism 5. The middle filtration mechanism 5 includes a filter barrel 501. The filter barrel 501 is provided with a plurality of arc plates 505 and ring mesh plates. These ring mesh plates are arranged from fine to coarse in terms of pore size, which can further remove fine particles and suspended matter in the water. The water flows through these arc plates 505 and ring mesh plates for multiple filtrations to ensure further purification of the water quality.

[0050] After a period of use, when the accumulation on the surface of the ring mesh plate inside the middle filter mechanism 5 reaches a certain level, the water inlet pipe 5015 connected to the filtration system will be connected to the water flow, and the water flow will be sprayed out through the circular nozzle 5010 and flush the surface of the ring mesh plate to remove the attached impurities and dirt. After rinsing, the water flow will take away the attachments through the pipe. If the ring mesh plate needs to be replaced, first disconnect the filter barrel 501 from the water pump 2 7, then pull the pull rod 406 to separate it from the U-shaped card plate 502 of the connection part between the filter barrel 501 and the filter, then rotate the fixing device 509, open it to disassemble the ring mesh plate assembly, take out the ring mesh plate with multiple arc plates 505, unplug the pin 508, and then disassemble the ring mesh plate 505 for cleaning or replacement. After the replacement is completed, reassemble it in the reverse order and put the new ring mesh plate back into the filter barrel 501 to ensure the normal operation of the entire filtration system.

[0051] The water treated by the medium filter mechanism 5 is sent into the interior of the housing 1 through the water pump 27. After entering the housing 1, the water first passes through the fine filter mechanism 2. The fine filter mechanism 2 includes multiple drawers 201. Each drawer 201 is equipped with a filter plate 203 of different materials. These filter plates are made of different materials according to the required filtering effect, such as polypropylene PP, stainless steel, activated carbon, etc., and have different filtering characteristics. For example, the activated carbon filter plate can remove organic pollutants in the water, the stainless steel filter plate can effectively remove larger particles, and the polypropylene filter plate is suitable for high-flow filtration. The filter plates in each drawer 201 perform physical filtration through the waist-shaped holes 205. When the water flows through, different filter plates 203 can select different filtering effects as needed, thereby improving the filtering efficiency.

[0052] After the water flows through the first filter drawer 201, it continues to pass through the second filter drawer 201, where the filter plates work to further remove suspended matter and pollutants in the water, ensuring that the water quality reaches a higher level of cleanliness;

[0053] The water passing through the second fine filter drawer 201 flows to the bottom of the fixed partition 106, and then passes through the remaining two fine filter mechanisms 2 from the bottom. The working principles and functions of these fine filter drawers 201 are the same as those described above, but due to the different filter plate materials, the purification effect of each one is different.

[0054] After the water has been processed multiple times by the fine filtration mechanism 2, it finally flows out from the top of the fixed partition 107 and enters the water inlet hopper 15. Subsequently, the water enters the pipeline-type ultraviolet disinfection lamp 14 through the pipe. The ultraviolet disinfection lamp can effectively kill bacteria and pathogens in the water, further ensuring the safety and cleanliness of the water.

[0055] The disinfected water enters the inner chamber formed by the fixed partition 3 108. At this time, the ammonia nitrogen sensor 11 in the inner chamber monitors the ammonia nitrogen concentration in the water in real time. If the ammonia nitrogen concentration is low, the system activates the microbubble generator 13 to release tiny bubbles, increasing the dissolved oxygen in the water, improving the water's self-purification ability, and further improving the water quality.

[0056] After these purification, disinfection and adjustment processes, the water finally flows out from multiple drainage pipes 101, completing the entire water quality circulation and purification process. During this process, the central control system collects data from the pH sensor 9, turbidity sensor 10, ammonia nitrogen sensor 11 and dissolved oxygen sensor 12 in real time, and dynamically adjusts the working status of equipment such as the water pump, ultraviolet disinfection lamp, and microbubble generator 13 to ensure that the water quality is always in the best condition and provide the ideal environment required for sea bass farming.
