[0002] In the field of aquaculture, the purification treatment of the aquaculture water body is crucial to the healthy growth of aquatic animals. The traditional static treatment pool of aquaculture auxiliary pond has certain limitations in structure design and function implementation, such as difficulty in effectively preventing fish from entering the treatment pool, easy deposition of sediments at the bottom of the pool, poor water exchange and filtration effect, etc., which cannot meet the demand of efficient treatment of aquaculture wastewater. SUMMARY

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a static treatment pool structure of aquaculture auxiliary pond.

[0004] To achieve the above-mentioned purpose, the utility model provides a static treatment pool structure of aquaculture auxiliary pond, which comprises a water pool and a filter assembly arranged in the water pool. The side of the water pool is provided with a water outlet pipe body and a water inlet pipe body, both of which are in communication with the water pool. The ends of the water outlet pipe body and the water inlet pipe body away from the water pool are connected with an aquaculture pond outside. The water inlet pipe body comprises a first extension pipe body and a central drainage valve. The central drainage valve is arranged in a water collecting pit at the bottom of the aquaculture pond. One end of the first extension pipe body is in communication with the water pool, and the end away from the water pool extends to the water collecting pit of the aquaculture pond and is in communication with the central drainage valve.

[0005] The central drainage valve is embedded in the water collecting pit of the aquaculture pond, and the siphon effect and the strip hole anti-escape design (strip hole diameter 5-8mm) are used to improve the collection rate of the pollutants at the bottom of the pool to more than 98%, which reduces the deposition blind area by 40% compared with the traditional corner drainage scheme. The limit column and the bushing flange interference fit (interference amount 0.1-0.2mm) are used to realize fast and accurate installation, and ensure that the impact displacement is less than 0.5mm under the flow rate of 1.5m / s.

[0006] The central drainage valve in the water inlet pipe body is arranged in the water collecting pit of the aquaculture pond, and is in communication with the first extension pipe body and the water pool, which can accurately collect the wastewater in the aquaculture pond. After being treated by the filter assembly in the water pool, the wastewater is returned to the aquaculture pond through the water outlet pipe body, realizing the circulation and purification of the water body, effectively removing impurities and pollutants, and improving the water quality of aquaculture. In specific implementation, the water pool is installed according to the design position, the filter assembly is reasonably arranged in the water pool, the water outlet pipe body and the water inlet pipe body are connected with the aquaculture pond, and the central drainage valve is located in the water collecting pit of the aquaculture pond and is stably connected with the first extension pipe body, so as to form a complete water treatment system, which ensures the stability of the aquaculture environment.

[0007] The filter assembly can also be a sand filter, an activated carbon filter and a mechanical filter. The sand filter uses granular filter material such as sand for filtration. When water passes through the sand layer, suspended particles are trapped in the gaps between the sand particles, thereby achieving the purpose of purifying water quality. The sand filter has good filtering effect and can effectively remove fine particles in water. Activated carbon has strong adsorption capacity and can adsorb pigments, odors, residual drugs and part of heavy metal ions in pond water. It can effectively improve the sensory properties of water and make the water clear and transparent. The mechanical filter intercepts suspended particles such as leaves, sand, fish manure and the like in pond water through physical media such as filter screen and filter cotton, prevents them from accumulating in the pond and affecting water quality.

[0008] The central drainage valve comprises a first cylinder, a first interface arranged at the side of the first cylinder, and a plurality of strip holes formed in the first cylinder to prevent fish in the breeding pond from entering the pool.

[0009] These strip holes can effectively prevent fish in the breeding pond from entering the treatment pool, avoid fish from being injured or even killed due to mistaken entry into the treatment pool, and also prevent fish from blocking the filter assembly and other structures in the treatment pool, thereby ensuring normal operation of the treatment pool. In the case of allowing the breeding pond sewage to flow smoothly into the first cylinder and enter the pool for treatment through the first extension pipe body, the size of the strip holes is reasonably set to ensure the flow of sewage and block fish. In implementation, the length and width of the strip holes are accurately designed according to the size of the breeding fish, and the strip holes are processed according to the design requirements during the manufacturing process of the first cylinder. After the central drainage valve is installed, the collection of sewage can be realized while preventing fish from entering the treatment pool, thereby maintaining stable operation of the aquaculture system.

[0010] The central drainage valve further comprises a fixing assembly arranged on the first cylinder; the first interface is connected with the first extension pipe body, and the fixing assembly comprises a bushing flange fixedly arranged at the bottom of the first cylinder and an installation pipe body installed in the first cylinder. The installation pipe body comprises a first circular bottom disc, a first long pipe arranged on the first circular bottom disc, and a limiting column arranged on the other side of the first circular bottom disc opposite to the first long pipe. The breeding pond sump is provided with a central hole for accommodating the bushing flange, and the bottom of the first cylinder is provided with an installation hole in communication with the central hole of the bushing flange. The limiting column protrudes out of the installation hole and is in interference fit with the central hole of the bushing flange to fix the central drainage valve in the breeding pond sump.

[0011] The first interface is connected with the first extension pipe body, so that the stability of sewage transportation is ensured; in the fixing assembly, the bushing flange is matched with the center hole of the water collecting pit of the culture pond, the limiting column on the installation pipe body passes through the bottom installation hole of the first cylinder and is in interference fit with the center hole of the bushing flange, so that the first cylinder is stably fixed, and the first circular bottom plate and the first long pipe further enhance the structural strength of the installation pipe body, and ensure that the center drain valve is stable in the water collecting pit. In specific implementation, first, a center hole is reserved in the water collecting pit of the culture pond, the bushing flange is fixed at the bottom of the first cylinder, the installation pipe body is installed in the first cylinder, the limiting column corresponds to the installation hole, then the center drain valve is placed in the water collecting pit as a whole, the installation is completed through the interference fit of the limiting column and the center hole, and the first interface and the first extension pipe body are connected, so that the function of stably collecting sewage in the culture pond and transporting the sewage to the pool for treatment is realized. The bushing flange is fixedly arranged at the bottom of the first cylinder, can provide additional structural support for the first cylinder, enhance the structural strength of the center drain valve as a whole, enable the center drain valve to withstand certain external force and water pressure, adapt to the complex working environment of the culture pond, and prolong the service life of the center drain valve.

[0012] The filter assembly comprises a plurality of aeration devices arranged around the side of the pool, the aeration device comprises an aeration ring arranged in the pool, an aeration connecting pipe in communication with the aeration ring, and the aeration connecting pipe protrudes out of the water surface of the pool at one end away from the aeration ring and is detachably connected with an external air source supply; the external air source supply drives the aeration device to release air into the pool to form bubbles, and the bubbles stir the water to be treated in the pool to prevent the deposition of the sediment in the water to be treated in the pool.

[0013] The plurality of aeration devices are arranged around the side of the pool, the aeration ring cooperates with the aeration connecting pipe, the aeration connecting pipe is detachably and sealingly connected with the external air source supply, different air sources can be flexibly connected, when the external air source supply drives the aeration device to release air into the pool to form bubbles, the bubbles can effectively stir the water to be treated in the process of rising in the water, the static balance of the water body is broken, the deposition of the sediment in the pool is difficult, the water quality purification effect is not affected by the deposition of the sediment, the dissolved oxygen content of the water body is increased, a good environment is provided for the growth and metabolism of microorganisms, the decomposition of pollutants in the water body is promoted, and the treatment efficiency is improved. In specific implementation, during the construction of the pool, the aeration ring is installed at the designed position, the aeration connecting pipe is connected with the aeration ring and protrudes out of the water surface at one end, a suitable external air source supply is selected, the aeration connecting pipe and the external air source supply are stably connected through sealing connection, the air source supply is debugged, and normal operation of the aeration device is ensured, so that efficient treatment of the water in the pool can be realized.

[0014] The filter assembly further comprises an air flow lifting module, the water inlet end of the air flow lifting module is in communication with the water body of the pool, and the water outlet end of the air flow lifting module is in communication with the water outlet pipe body.

[0015] The airflow boosting module includes a pneumatic conveying component, which includes a pneumatic conveying cone and an aeration chassis connected to the bottom surface of the pneumatic conveying cone. The pneumatic conveying cone is connected to the outlet pipe. The cross-sectional diameter of the pneumatic conveying cone gradually decreases from the bottom to the top.

[0016] The outlet pipe body has an air inlet protruding above the water surface at one end near the pneumatic conveying cone; the side inlet end of the pneumatic conveying cone has an inlet filter connected to the pneumatic conveying cone; after the water to be treated is filtered by the inlet filter, the filtered water flows into the lower part of the pneumatic conveying cone, and the aeration tray releases airflow into the pneumatic conveying cone through the aeration holes, forming a gas-liquid mixed upward flow. The gas-liquid mixed flow is accelerated upward under the action of the gradually narrowing cross section of the pneumatic conveying cone, and the accelerated gas-liquid mixed flow enters the internal channel of the outlet pipe body through the top outlet of the pneumatic conveying cone, and is transported to the external treatment unit through the outlet pipe body. The air inlet replenishes the air source into the outlet pipe body to accelerate the transport of the gas-liquid mixed flow to the external treatment unit.

[0017] The cross-sectional diameter of the pneumatic conveying cone gradually decreases from bottom to top. In conjunction with the aeration chassis, the aeration chassis releases airflow through aeration holes. This airflow, after being filtered by the inlet filter, forms a gas-liquid mixture rising upwards. Under the action of the gradually narrowing cross-section of the pneumatic conveying cone, this upward flow is accelerated, efficiently lifting and transporting the water. The air inlet of the outlet pipe replenishes the air supply, further accelerating the gas-liquid mixture flow and ensuring the treated water quickly flows to the external treatment unit. Simultaneously, the inlet filter intercepts impurities, preventing blockage of the conveying channel and ensuring stable system operation. During implementation, the aeration chassis is installed on the bottom of the pneumatic conveying cone, the inlet filter is installed on the side of the cone and connected to the water in the pool, the top of the pneumatic conveying cone is connected to the outlet pipe, and an air inlet is installed at the corresponding position on the outlet pipe. After installation, the operating parameters of each component are adjusted to achieve efficient water lifting and transport, improving the overall efficiency of the treatment system.

[0018] The water inlet filter includes a filter housing and filter beads filled inside the filter housing. The filter housing has filter holes on the outside. The water to be treated flows into the filter housing through the filter holes, and the filter beads inside the filter housing filter the water to be treated.

[0019] The inlet filter element can be a cartridge filter, using a PTFE pleated cartridge (pleat depth 10mm, pleat spacing 3mm), with a silver ion antibacterial coating (silver content 1wt%) loaded on the surface of the cartridge.

[0020] The filter shell's outer filtration holes allow the water to flow in, while the internal filter beads effectively intercept suspended solids and impurities, purifying the water through physical filtration. This prevents these impurities from entering the pneumatic conveying cone and subsequent pipes, avoiding blockages and ensuring the formation and transport efficiency of the gas-liquid mixture. This guarantees the stable operation of the airflow booster module and the entire filtration assembly. During implementation, filter beads are filled into the filter shell, which is then sealed. The assembled filter shell is installed on the side inlet of the pneumatic conveying cone, ensuring its filtration holes are connected to the water in the pool. This allows for preliminary filtration before the water enters the pneumatic conveying cone, improving the overall treatment effect and providing a reliable guarantee for water purification in aquaculture.

[0021] The first extension pipe is equipped with a vane valve, which is used to control the flow rate and velocity of the water in the first extension pipe and to regulate the amount of water exchange between the water tank and the aquaculture tank.

[0022] By manipulating the leaf valve, the flow rate and velocity of water within the first extension pipe can be flexibly and precisely controlled, thereby effectively regulating the water exchange between the water tank and the aquaculture tank. When the aquaculture tank has a high demand for water purification, the leaf valve can be opened wider to increase the water exchange volume, allowing more wastewater to enter the water tank for treatment; when the water quality is good, the leaf valve can be closed to reduce water exchange and lower energy consumption. In practice, the leaf valve is installed at a suitable position in the first extension pipe. By rotating or moving the leaf valve blades, its opening angle can be changed to control the water flow rate and velocity. The operation is simple and convenient, helping to maintain stable water quality in the aquaculture tank and improving the operational efficiency and practicality of the static treatment tank in the aquaculture auxiliary tank.

[0023] The static treatment tank structure also includes a water level monitoring device installed in the tank. The water level monitoring device is electrically connected to an external control unit. When the water level in the tank exceeds the preset range, the control unit controls the valves on the inlet or outlet pipes to make adjustments.

[0024] The water level monitoring device monitors the water level in the pool in real time. Once the water level exceeds the preset range, it transmits a signal to the external control unit. The control unit reacts quickly and automatically controls the valves on the inlet or outlet pipes to adjust the level. When the water level is too high, the control unit opens the outlet valve to accelerate water discharge; when the water level is too low, it controls the inlet valve to increase the inflow, ensuring the water level in the pool remains within a reasonable range. This not only avoids system malfunctions caused by abnormal water levels, such as overflow and equipment idling, but also makes the water exchange between the pool and the aquaculture pond more scientific and orderly. In implementation, the water level monitoring device is installed appropriately in the pool, connected to the circuit of the external control unit, and the upper and lower water level thresholds are set in the control unit. The valves of the inlet and outlet pipes are connected to the control unit. After debugging, automated water level monitoring and control can be achieved, ensuring the efficient and stable operation of the aquaculture auxiliary static treatment pond.

[0025] The first long pipe acts as a rigid support component, forming a double fixing mechanism with the limiting column to prevent the drainage screen from shifting due to water flow impact.

[0026] The beneficial effects of this utility model are as follows: Utilizing the siphon effect and the central drain valve's perforated design, the central drain valve is precisely embedded into the aquaculture pond's collection pit. Combined with the interference fit between the limiting column and the bushing flange, it efficiently collects bottom debris and reduces sedimentation blind spots. The aeration device in the filtration assembly prevents sediment buildup through bubble agitation, while simultaneously increasing dissolved oxygen levels and promoting pollutant decomposition. The airflow booster module uses a pneumatic conveying cone and an aeration base to create a gas-liquid mixture and upward flow, accelerating water transport. The inlet filter, blade valve, and water level monitoring device respectively achieve impurity filtration, flow regulation, and intelligent water level control. The overall structure, through the coordinated operation of its components, achieves water circulation and purification, effectively removing impurities and pollutants, ensuring stable water quality in aquaculture, and improving system operating efficiency and reliability.

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0036] Please see Figures 1 to 6 As shown, the present invention discloses a static treatment tank structure for an aquaculture auxiliary pond, comprising a water tank 1 and a filter assembly 2 disposed within the water tank 1; the water tank 1 is provided with an outlet pipe 3 and an inlet pipe 4 on its side, both of which are connected to the water tank 1. The ends of the outlet pipe 3 and the inlet pipe 4 away from the water tank 1 are connected to an external aquaculture pond 7. The inlet pipe 4 includes a first extension pipe 5 and a central drain valve, which is disposed in a water collection pit at the bottom of the aquaculture pond 7. One end of the first extension pipe 5 is connected to the water tank 1, and the end away from the water tank 1 extends to the water collection pit of the aquaculture pond 7 and is connected to the central drain valve.

[0037] The central drain valve is embedded in the 7-sump water collection pit of the aquaculture pond. Utilizing the siphon effect and the escape-proof design of the 17-hole strip (hole diameter 5-8mm), the collection rate of sludge at the bottom of the pond is increased to over 98%, reducing the sedimentation blind zone by 40% compared to traditional corner drainage solutions. During implementation, the limit column 16 and the bushing flange 12 are interference-fitted (interference amount 0.1-0.2mm) to achieve quick and accurate installation, ensuring that the impact displacement is <0.5mm at a flow rate of 1.5m / s.

[0038] By installing a central drain valve in the inlet pipe 4 in the water collection pit of the aquaculture pond 7, and connecting it with the first extension pipe 5 to the water tank 1, wastewater from the aquaculture pond 7 can be accurately collected. After being treated by the filter assembly 2 in the water tank 1, the wastewater flows back to the aquaculture pond 7 through the outlet pipe 3, realizing water circulation and purification. This effectively removes impurities and pollutants, improving the quality of the aquaculture water. In specific implementation, the water tank 1 is installed according to the design location, the filter assembly 2 is arranged reasonably in the water tank 1, and the outlet pipe 3 and the inlet pipe 4 are connected to the aquaculture pond 7. The central drain valve is located in the water collection pit of the aquaculture pond 7 and is firmly connected to the first extension pipe 5, thus forming a complete water treatment system to ensure the stability of the aquaculture environment.

[0039] The central drain valve includes a first cylinder 8 and a first interface 9 located on the side of the first cylinder 8. The first cylinder 8 has multiple sets of slots 17 to prevent fish in the aquaculture pond 7 from entering the water tank 1.

[0040] These perforations 17 effectively prevent fish from entering the treatment tank from the aquaculture pond 7, avoiding injury or even death to the fish due to accidental entry. They also prevent fish from clogging the filter components 2 and other structures within the treatment tank, ensuring its normal operation. While allowing wastewater from the aquaculture pond 7 to flow smoothly into the first cylinder 8 and then into the water tank 1 for treatment via the first extension pipe 5, the appropriately sized perforations 17 ensure both sufficient wastewater flow and prevent fish from entering. In implementation, the length and width of the perforations 17 are precisely designed according to the size of the farmed fish. During the manufacturing process of the first cylinder 8, the perforations 17 are machined according to the design requirements. After installing the central drain valve, wastewater collection is achieved while preventing fish from entering the treatment tank, maintaining the stable operation of the aquaculture system.

[0041] The central drain valve also includes a fixing component 11 disposed on the first cylinder 8; the first interface 9 is connected to the first extension pipe 5, and the fixing component 11 includes a bushing flange 12 fixedly disposed at the bottom of the first cylinder 8 and an installation pipe installed inside the first cylinder 8. The installation pipe includes a first circular base 14, a first long pipe 15 disposed on the first circular base 14 and a limiting post 16. The limiting post 16 is disposed on the other side of the first circular base 14 opposite to the first long pipe 15. The water collection pit of the aquaculture pond 7 is provided with a central hole for accommodating the bushing flange 12. The bottom of the first cylinder 8 is provided with an installation hole communicating with the central hole of the bushing flange 12. The limiting post 16 protrudes from the installation hole and is interference-fitted with the central hole of the bushing flange 12 to fix the central drain valve in the water collection pit of the aquaculture pond 7.

[0042] The first interface 9 is connected to the first extension pipe 5 to ensure the stability of sewage transportation. In the fixing assembly 11, the bushing flange 12 is adapted to the center hole of the water collection pit of the aquaculture pond 7. The limiting post 16 on the mounting pipe passes through the mounting hole at the bottom of the first cylinder 8 and is interference-fitted with the center hole of the bushing flange 12 to firmly fix the first cylinder 8. The first circular base plate 14 and the first long pipe 15 further enhance the structural strength of the mounting pipe to ensure that the central drain valve is stable in the water collection pit. In specific implementation, a center hole is first reserved in the water collection pit of the aquaculture pond 7, the bushing flange 12 is fixed to the bottom of the first cylinder 8, the mounting pipe is installed in the first cylinder 8 so that the limiting post 16 corresponds to the mounting hole, and then the central drain valve is placed in the water collection pit. The installation is completed by the interference fit between the limiting post 16 and the center hole. Then the first interface 9 is connected to the first extension pipe 5 to realize the function of stably collecting sewage from the aquaculture pond 7 and transporting it to the water tank 1 for treatment. The bushing flange 12 is fixedly installed at the bottom of the first cylinder 8, which can provide additional structural support for the first cylinder 8, enhance the overall structural strength of the central drain valve, enable it to withstand certain external forces and water pressure, adapt to the complex working environment of the aquaculture pond 7, and extend its service life.

[0043] The filter assembly 2 includes multiple sets of aeration devices 18 arranged around the side of the water tank 1. Each aeration device 18 includes an aeration ring 19 arranged in the water tank 1 and an aeration connecting pipe 21 connected to the aeration ring 19. The end of the aeration connecting pipe 21 away from the aeration ring 19 protrudes from the water surface of the water tank 1 and is detachably connected to an external air source supply. The external air source supply drives the aeration device 18 to release air into the water tank 1 to form bubbles, which stirs the water to be treated in the water tank 1 to prevent sediment in the water to be treated from settling at the bottom of the tank.

[0044] Multiple aeration devices 18 are arranged in a ring around the side of the water tank 1. Aeration rings 19 cooperate with aeration connecting pipes 21. By detachably and sealingly connecting the aeration connecting pipes 21 to an external air source supply, different air sources can be flexibly connected. When the external air source supply drives the aeration devices 18 to release air into the water tank 1, forming bubbles, the rising of these bubbles effectively stirs the water, breaking the static balance of the water body and making it difficult for sediment to settle at the bottom of the tank. This avoids affecting the water purification effect due to sediment accumulation, while simultaneously increasing the dissolved oxygen content of the water, providing a good environment for the growth and metabolism of microorganisms, promoting the decomposition of pollutants in the water, and improving treatment efficiency. In specific implementation, during the construction of the water tank 1, the aeration rings 19 are installed according to the design position. The aeration connecting pipes 21 are connected to the aeration rings 19, with one end extending above the water surface. A suitable external air source supply is then selected, and the two are securely connected through a sealing connection. The air source supply is adjusted to ensure the normal operation of the aeration devices 18, thus achieving efficient treatment of the water in the water tank 1.

[0045] The filter assembly 2 also includes an airflow boosting module 22, the inlet of which is connected to the water body of the pool 1, and the outlet of which is connected to the outlet pipe 3.

[0046] The airflow lifting module 22 includes a pneumatic conveying component, which includes a pneumatic conveying cone 23 and an aeration chassis 24 connected to the bottom surface of the pneumatic conveying cone 23. The pneumatic conveying cone 23 is connected to the water outlet pipe 3. The cross-sectional diameter of the pneumatic conveying cone 23 gradually decreases from the bottom to the top.

[0047] The outlet pipe 3 has an air inlet 25 protruding from the water surface at one end near the pneumatic conveying cone 23; the side water inlet end of the pneumatic conveying cone 23 has an inlet filter 26 connected to the pneumatic conveying cone 23; after the water to be treated is filtered by the inlet filter 26, the filtered water flows into the lower part of the pneumatic conveying cone 23, and the aeration base 24 releases airflow into the pneumatic conveying cone 23 through the aeration holes to form a gas-liquid mixed upward flow. The gas-liquid mixed flow is accelerated upward under the action of the gradually narrowing cross section of the pneumatic conveying cone 23, and the accelerated gas-liquid mixed flow enters the internal channel of the outlet pipe 3 through the top outlet of the pneumatic conveying cone 23, and is transported to the external treatment unit through the outlet pipe 3. The air inlet 25 replenishes the air source into the outlet pipe 3 to accelerate the gas-liquid mixed flow to the external treatment unit.

[0048] The cross-sectional diameter of the pneumatic conveying cone 23 gradually decreases from bottom to top. It works in conjunction with the aeration chassis 24, which releases airflow through aeration holes. This causes the water to be treated to pass through the inlet filter 26, forming a gas-liquid mixed upward flow. Under the action of the gradually narrowing cross-section of the pneumatic conveying cone 23, this upward flow is accelerated, efficiently lifting and transporting the water. The air inlet 25 of the outlet pipe 3 replenishes the air supply, further accelerating the gas-liquid mixed flow and ensuring the treated water flows quickly to the external treatment unit. Simultaneously, the inlet filter 26 intercepts impurities, preventing blockage of the conveying channel and ensuring stable system operation. In implementation, the aeration chassis 24 is installed on the bottom surface of the pneumatic conveying cone 23, the inlet filter 26 is installed on the side of the pneumatic conveying cone 23 and connected to the water in the pool 1, the top of the pneumatic conveying cone 23 is connected to the outlet pipe 3, and the air inlet 25 is set at the corresponding position on the outlet pipe 3. After installation, the operating parameters of each component are adjusted to achieve efficient water lifting and transport, improving the overall efficiency of the treatment system.

[0049] The water inlet filter element 26 includes a filter shell 27 and filter beads 28 filled inside the filter shell 27. The filter shell 27 has filter holes on its outer side. The water to be treated flows into the filter shell 27 through the filter holes, and the filter beads 28 inside the filter shell 27 filter the water to be treated.

[0050] The inlet filter element 26 can be a cartridge filter, using a PTFE pleated filter element (pleat depth 10mm, pleat spacing 3mm), with a silver ion antibacterial coating (silver content 1wt%) loaded on the filter element surface.

[0051] The filter shell 27 has external filter holes that allow water to flow in, while the filter beads 28 inside effectively intercept suspended solids and impurities in the water. This physical filtration purifies the water and prevents these impurities from entering the pneumatic conveying cone 23 and subsequent pipes, thus avoiding blockages and ensuring the stable operation of the airflow booster module 22 and the entire filter assembly 2. During implementation, the filter beads 28 are filled into the filter shell 27, which is then sealed. The assembled filter shell 27 is installed on the side inlet of the pneumatic conveying cone 23, ensuring its filter holes are connected to the water in the pool 1. This allows for preliminary filtration of the water before it enters the pneumatic conveying cone 23, improving the overall treatment effect and providing a reliable guarantee for water purification in aquaculture.

[0052] The first extension pipe body 5 is equipped with a blade valve 29, which is used to control the flow rate and velocity of water in the first extension pipe body 5 and to regulate the amount of water exchange between the water tank 1 and the aquaculture tank 7.

[0053] By manipulating the leaf valve 29, the flow rate and velocity of water within the first extension pipe 5 can be flexibly and precisely controlled, thereby effectively regulating the water exchange between the water tank 1 and the aquaculture tank 7. When the water purification demand in the aquaculture tank 7 is high, the leaf valve 29 can be opened wider to increase the water exchange, allowing more wastewater to enter the water tank 1 for treatment; when the water quality is good, the leaf valve 29 can be closed to reduce water exchange and lower energy consumption. In practice, the leaf valve 29 is installed at a suitable position in the first extension pipe 5. By rotating or moving the blades of the leaf valve 29, its opening angle can be changed to control the water flow rate and velocity. The operation is simple and convenient, helping to maintain the stability of the water quality in the aquaculture tank 7 and improving the operational efficiency and practicality of the static treatment tank in the aquaculture auxiliary tank.

[0054] The static treatment tank structure also includes a water level monitoring device 31 installed in the water tank 1. The water level monitoring device 31 is electrically connected to an external control unit. When the water level in the water tank 1 exceeds the preset range, the control unit controls the valve on the inlet pipe 4 or the outlet pipe 3 to make adjustments.

[0055] The water level monitoring device 31 monitors the water level in pool 1 in real time. Once the water level exceeds the preset range, it transmits a signal to the external control unit. The control unit reacts quickly and automatically controls the valves on the inlet pipe 4 or outlet pipe 3 for adjustment. When the water level is too high, the control unit opens the outlet pipe 3 valve to accelerate water discharge; when the water level is too low, it controls the inlet pipe 4 valve to increase the water inflow, ensuring that the water level in pool 1 is always within a reasonable range. This not only avoids system failures caused by abnormal water levels, such as overflow and equipment idling, but also makes the water exchange between pool 1 and aquaculture pool 7 more scientific and orderly. In implementation, the water level monitoring device 31 is properly installed in pool 1, connected to the circuit of the external control unit, the upper and lower limit thresholds of the water level are set in the control unit, and the valves of the inlet pipe 4 and outlet pipe 3 are connected to the control unit. After debugging, the automatic monitoring and control of the water level can be realized, ensuring the efficient and stable operation of the static treatment pool of the aquaculture auxiliary pool.
