Description

Technical Field

[0001] This invention relates to the field of aquaculture water purification, specifically a water filtration and circulation purification device for improving the quality of farmed bass. Background Technology

[0002] As a high-value farmed fish, the growth environment of sea bass directly affects its quality, survival rate, and market competitiveness. Under high-density farming conditions, fish metabolites, uneaten feed, suspended particles, and microorganisms accumulate in the water, leading to changes in the physical, chemical, and biological characteristics of the water, such as turbidity, increased ammonia nitrogen concentration, and insufficient dissolved oxygen. These problems not only affect the growth rate of sea bass but also lead to decreased immunity and increased disease risk.

[0003] Currently, common water purification methods in aquaculture mainly rely 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 decompose harmful substances such as ammonia nitrogen and nitrite in the water, reducing their toxicity to fish. In addition, regular water changes are widely used to dilute pollutants in the water to maintain water quality stability. While these technologies can improve the aquatic environment to some extent, they still have many technical limitations and cannot meet the demands of modern aquaculture for efficient, energy-saving, and intelligent water quality management.

[0004] First, water quality monitoring mainly relies on manual testing, which is slow to adjust and has low accuracy, making it difficult to respond promptly to changes in water quality and easily leading to water quality deterioration. Second, single-layer filtration has limited effectiveness in removing impurities of different particle sizes, easily causing filter clogging, affecting water flow, and thus reducing purification efficiency. In addition, high water exchange frequency leads to water waste, increases energy consumption and operating costs, and traditional chemical disinfection methods may disrupt the ecological balance of the aquatic body, affecting the healthy growth of sea bass. Therefore, a water filtration and circulation purification device to improve the quality of farmed sea bass is proposed to solve the above problems. Summary of the Invention

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides a water filtration and circulation purification device for improving the quality of farmed sea bass, comprising a housing 1. Inside the housing 1 are fixed partitions 106, 107, and multiple U-shaped plates 105. These structures form independent filtration zones and ensure that the water flows along a predetermined path for filtration and circulation purification. A U-shaped plate 105 is positioned between the fixed partition 106 and the inner wall of the housing 1, and another U-shaped plate 105 is positioned between the fixed partition 106 and the 107. A cover 104 is installed on the top of partition 106. This cover 104 is used to seal the filtration system and prevent external pollutants from entering. It is also firmly connected to the top of the housing 1 with bolts to ensure airtightness and improve the durability of the equipment. The cover 104 is connected to the top of the housing 1 with bolts. The side of the housing 1 away from the cover 104 is connected to cover 102 with multiple hinges, allowing the housing 1 to be easily opened for equipment maintenance and internal component replacement. Fine filters slide between the U-shaped plates 105. Structure 2 ensures that water flows through multiple independent filtration zones, further enhancing the purification effect and preventing short-circuiting of water flow from affecting filtration quality. To enhance the layering of the filtration space and improve filtration efficiency, multiple intermediate filtration mechanisms 5 are also installed on the outside of the housing 1. The inlet of the intermediate filtration mechanism 5 is connected to the coarse filtration mechanism 6 via a water pump 3. A handle 103 is provided on the top of the housing cover 102 to ensure that the operator can easily open the equipment for maintenance or replacement of filter components. The housing cover 102 is connected to the housing cover 2 104 by multiple buckles. The top of the cover 104 is also equipped with multiple water pumps 7 at equal intervals. These water pumps are used to drive water flow into the filtration zone and ensure continuous water flow in the system, thereby improving water purification efficiency. The output end of the water pump 7 is connected to the cover 104 via a pipe, and the input end of the water pump 7 is connected to the outlet pipe 5011 via a quick-release head. The quick-release head design facilitates the disassembly and maintenance of the water pump, improves the operability and durability of the equipment, and ensures that the water flows into different filtration zones according to a predetermined path, thereby achieving graded filtration and gradually improving water quality.

[0038] The fine filtration mechanism 2 includes drawers 201, all positioned between U-shaped plates 105. Each drawer 201 is bolted to the housing 1, allowing for easy disassembly, cleaning, and replacement. A U-shaped groove 202 is provided on the side of each drawer near the intermediate filtration mechanism 5. This groove is specifically designed to house the turbidity sensor 10 and pH sensor 9, ensuring they can monitor water quality in real time and feed data back to the central control system. Each drawer 201 contains a filter plate 203. The material of this filter plate can be selected based on water quality requirements, for example: polypropylene (PP) filter plates (suitable for high-flow filtration); stainless steel filter plates (removing larger particles and improving durability); and activated carbon filter plates (effectively adsorbing organic pollutants in the water). To eliminate impurities and odors and improve water purity, multiple waist-shaped holes 205 are provided on the surface of both drawer 201 and U-shaped channel 202. The waist-shaped holes 205 ensure smooth water flow and prevent impurities from accumulating and affecting the filtration effect. The rear of the waist-shaped holes 205 is connected to the baffle 204 by bolts. The filter plate 203 can be replaced by removing the baffle 204. A pH sensor 9 is installed inside the upper U-shaped channel 202, and a turbidity sensor 10 is installed inside the lower U-shaped channel 202. The pH sensor 9 and the turbidity sensor 10 transmit the collected data to the central control system. The pH sensor 9 is used to monitor the acidity and alkalinity of the water to ensure that the water to be purified is within the pH range suitable for the growth of bass. The turbidity sensor 10 is used to detect the suspended solids content in the water to be purified to ensure that the water is clear and transparent.

[0039] Please see the appendix Figure 5 The latching mechanism 4 includes a second U-shaped plate 401, which is set outside the filter tank 501 to ensure stable fixation of the filter assembly and facilitate disassembly and replacement. A latching rod 402 slides on the inner side of the second U-shaped plate 401. A limit plate 403 is set at the bottom of each latching rod 402 to limit the movement range of the latching rod 402, ensuring that the filter assembly is stable and does not loosen, thus improving the reliability of equipment operation. A second limit plate 405 is also set outside the latching rod 402. A spring 404 is set between the second limit plate 405 and the second U-shaped plate 401 to provide the ability to reset. A pull rod 406 is also set on the outer side of the latching rod 402. The latching rod 402 passes through the corresponding U-shaped latching plate 502 and L-shaped latching plate 5016 and engages with them. When it is necessary to disassemble the filter assembly, the latching rod 402 will disengage from its original engaging state by pulling the pull rod 406, allowing the filter assembly to be disassembled smoothly and improving the maintainability of the equipment.

[0040] Please see the appendix Figure 6 -Appendix Figure 10The intermediate filtration mechanism 5 includes a filter barrel 501, which is located on the outside of the housing 1. The filter barrel 501 is used to carry and perform the intermediate filtration process of the water, ensuring that the water quality reaches the basic purification standard before entering the fine filtration stage. The interior of the filter barrel 501 is symmetrically provided with arc grooves 504. These arc grooves 504 serve as fixed tracks for the arc plates 505, ensuring stable placement of the arc plates and providing positions for the pins 508 and hinges. Multiple arc plates 505 are provided on the inner side of each arc groove 504, and one side of each arc plate 505 is connected by hinges, allowing for flexible opening and easy cleaning and maintenance. The other side of each arc plate 505 is connected by pins 508, and the arc plates 505 are connected to each other by multiple fixed connecting rods 506. Multiple fixing connecting rods 506 are provided on the outer sides of both the lowest and uppermost arc plates 505 to improve structural stability and prevent the filter plates from falling off or deforming. A lid 509 is provided on the top of the filter barrel 501. The lid 509 effectively seals the filtration system, preventing external contaminants from entering, and facilitates the replacement and cleaning of internal components. Multiple L-shaped clamping plates 5016 are provided on the outer side of the lid 509, and multiple U-shaped clamping plates 502 are provided on the outer side of the filter barrel 501. The U-shaped clamping plates 502 engage with the corresponding L-shaped clamping plates 5016 to ensure the lid is fixed and easy to disassemble and replace. A latching mechanism 4 is also provided on the outer side of the filter barrel 501. The latching mechanism 4 engages with one of the L-shaped clamping plates 5016. Engaging with one of the L-shaped clamps 5016 further enhances the sealing of the filter barrel 501 and facilitates quick disassembly and maintenance of the components by operators. A circular spray pipe 5010 is installed inside the filter barrel 501 to wash away impurities on the filter screen. A water inlet pipe 5015 is installed at the top of the circular spray pipe 5010, and all water inlet pipes 5015 pass through the filter barrel 501, providing water and pressure to the circular spray pipe 5010. A water outlet pipe 5011 is installed at the top of the filter barrel 501, and a water outlet valve 503 is installed at the bottom of the filter barrel 501. When water is sprayed, the impurities washed down are carried away by the water flow and finally discharged through the water outlet valve 503 at the bottom of the filter barrel 501, ensuring that the filtration system is not affected by the accumulation of impurities. In effect, the inner side of the arc plate 505 is provided with arc grooves 507 for placing ring mesh plates of different levels to achieve layered filtration. Fine filter ring mesh plates 5012, medium filter ring mesh plates 5013, and coarse filter ring mesh plates 5014 are respectively arranged between the arc grooves 507, and these plates are arranged from high to low to ensure that impurities of different particle sizes are filtered layer by layer as the water flows through. The water first undergoes coarse filtration, then finer filtration, thus ensuring a high purification effect. The external inlet of the filter tank 501 is connected to the output end of the water pump 3 via a pipe to ensure smooth water flow into the medium filtration system. The input end of the water pump 3 is connected to the filter box 601 via a pipe.This allows water to directly enter the secondary filtration system after coarse filtration, improving filtration efficiency.

[0041] The coarse filtration mechanism 6 includes a filter box 601. A stainless steel mesh box 603 is installed inside the filter box 601 to initially intercept larger particles and facilitate unified cleaning. Multiple sets of clamping strips 604 are evenly arranged inside the stainless steel mesh box 603. The clamping strips 604 are used to fix filter screens of different specifications to ensure that the water can be evenly distributed when passing through, thereby improving filtration efficiency. Filter plates 602 are installed between the clamping strips 604. The diameter of the filter plates 602 gradually decreases from the outside to the inside, so that the water flows through multiple different levels of filtration layers in sequence, gradually removing larger particulate impurities and improving the effect of subsequent filtration.

[0042] A fixed partition 3 108 is installed between the fixed partition 2 107 and the inner wall of the box 1, forming an independent water optimization zone. A microbubble generator 13 is installed on the top of the fixed partition 3 108. This device is used to release microbubbles into the water to increase the dissolved oxygen content of the water and enhance the self-purification ability of the water. A pipeline ultraviolet disinfection lamp 14 is also installed on the top of the fixed partition 3 108 to kill bacteria and pathogens in the water and ensure water safety. Water inlet hoppers 15 are installed on the outer side of the fixed partition 2 107. The water inlet hoppers 15 are used to buffer the water flow and make the water flow smoothly into the ultraviolet disinfection system to improve the disinfection effect. The outlet of the water inlet hopper 15 is connected to the inlet of the pipeline ultraviolet disinfection lamp 14 through a pipe to ensure that the water flows through the ultraviolet disinfection lamp for sterilization. The outlet of the pipeline ultraviolet disinfection lamp 14 is connected to the fixed partition 3 108 through a pipe.

[0043] An inner chamber is formed between the fixed partition 3 108, the fixed partition 2 107 and the inner bottom wall of the box 1. Multiple drain pipes 101 are provided on the outside of the inner chamber to discharge the purified water that has passed through all the filtration stages. An ammonia nitrogen sensor 11 and a dissolved oxygen sensor 12 are respectively installed on the outside of the box 1 to detect the ammonia nitrogen content and dissolved oxygen level in the water. The ammonia nitrogen sensor 11 and the dissolved oxygen sensor 12 transmit the collected data to the central control system.

[0044] The exterior of the housing 1 is also equipped with a control box 8, which is electrically connected to water pump 3, water pump 7, pH sensor 9, turbidity sensor 10, ammonia nitrogen sensor 11, dissolved oxygen sensor 12, microbubble generator 13 and pipeline ultraviolet disinfection lamp 14, respectively, for centralized management and control of the operation of the entire water filtration and circulation purification device.

[0045] Please see the appendix Figure 11 The central control system includes:

[0046] Monitoring module: This module receives water quality data collected in real time from pH sensor 9, turbidity sensor 10, ammonia nitrogen sensor 11 and dissolved oxygen sensor 12, 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 relevant equipment based on the analysis results.

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

[0049] After coarse filtration, the water flows into the intermediate filtration mechanism 5 through water pump 2 7. The intermediate filtration mechanism 5 includes a filter barrel 501. The filter barrel 501 is equipped with multiple arc plates 505 and ring mesh plates. These ring mesh plates are arranged in order of increasing pore size, which can further remove fine particles and suspended solids 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 surface of the ring mesh plate inside the filter mechanism 5 accumulates to a certain extent, the water inlet pipe 5015 connected to the filter system will be connected to the water flow. The water flow will be sprayed out through the circular nozzle 5010 and wash the surface of the ring mesh plate to remove the attached impurities and dirt. After rinsing, the water flow will carry away the attached substances through the pipe. If the ring mesh plate needs to be replaced, first disconnect the filter barrel 501 from the water pump 7, then pull the pull rod 406 to separate it from the U-shaped clamp plate 502 connecting the filter barrel 501 and the filter. Next, rotate the fixing device 509 to open it to disassemble the ring mesh plate assembly, take out the ring mesh plate with multiple arc plates 505, pull out the pin 508, and then disassemble the ring mesh plate 505 for cleaning or replacement. After replacement, reassemble in the reverse order and put the new ring mesh plate back into the filter barrel 501 to ensure that the entire filter system operates normally.

[0051] After being treated by the intermediate filtration mechanism 5, the water is sent into the tank 1 by the second water pump 7. After entering the tank 1, the water first passes through the fine filtration mechanism 2, which includes multiple drawers 201. Each drawer 201 is equipped with a filter plate 203 of different materials. These filter plates use different materials, such as polypropylene (PP), stainless steel, and activated carbon, depending on the required filtration effect. They have different filtration characteristics. For example, activated carbon filter plates can remove organic pollutants from the water, stainless steel filter plates can effectively remove larger particles, and polypropylene filter plates are suitable for high-flow filtration. The filter plates in each drawer 201 perform physical filtration through the oblong holes 205. When the water flows through, different filter plates 203 can select different filtration effects as needed, thereby improving filtration 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 plate further removes suspended solids and pollutants from the water, ensuring that the water quality reaches a high level of cleanliness.

[0053] Water flowing 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. The working principle and function of these fine filter drawers 201 are the same as described above, but due to the different filter plate materials, the purification effect on the water varies from one to the other.

[0054] After the water body has been treated multiple times by the fine filtration mechanism 2, the water flow finally flows out from the top of the fixed baffle 2 107 and enters the water inlet hopper 15. Subsequently, the water body enters the pipeline 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 body.

[0055] After disinfection, the water enters the inner chamber formed by the fixed partition 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 will activate the microbubble generator 13 to release microbubbles, increase the dissolved oxygen in the water, enhance the self-purification ability of the water, and further optimize the water quality.

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

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
