Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, in particular to water circulation purification equipment used in aquaculture. Background Art

[0002] Aquaculture is the use of available waters for breeding by humans. According to the ecological habits of the breeding objects and the requirements of the water environment conditions, aquaculture technology and facilities are used to breed aquatic economic animals and plants. In order to ensure the growth and survival rate of aquatic products, water circulation purification equipment is needed to purify the water inside the breeding pond.

[0003] The application document for a water circulation purification device for aquaculture, filed under application number 202510315634.4, describes a multi-stage purification component that effectively removes large impurities, suspended solids, fine particles, organic matter, and odors from the water, improving purification efficiency. The device has a simple structure, making it easy to manufacture, maintain, and operate, reducing costs. The use of a biological filter layer and an activated carbon adsorption layer, along with an oxygenated fine filter cartridge, not only improves the water purification effect but also increases the dissolved oxygen content in the water, improving the water environment. Furthermore, through optimized piping design and the use of control valves, precise control of water flow is achieved, reducing energy consumption and complying with the development trend of energy conservation and emission reduction.

[0004] Although the above application has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: when filtering water, the filter net is easily blocked due to the accumulation of impurities, and requires frequent manual cleaning, which not only increases labor intensity, but also easily affects the water circulation efficiency due to untimely cleaning. After the impurities are collected, they are often discharged directly, resulting in a waste of water resources and may cause secondary pollution. In the water treatment process, the purification components are prone to loosening or displacement under the impact of water flow, resulting in the water flow flowing out without being fully filtered, resulting in poor water purification effect. In addition, the aeration components mostly rely on independent power sources and lack linkage with the filtration system, resulting in increased energy consumption. Based on this, the present invention designs a water circulation purification equipment for aquaculture to solve the above problems. Summary of the Invention

Qualified water flows directly back to the aquaculture pond, and unqualified water re-enters the treatment tank for secondary treatment through the return pipe. This closed-loop mechanism ensures that the water quality circulating back to the pond is absolutely up to standard, prevents poor-quality water from affecting the aquaculture environment, guarantees the ultimate effect of water circulation purification from the terminal, and reduces aquaculture risks.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Example: Figure 1-Figure 3 As shown, the present invention provides a technical solution, a water circulation purification equipment for aquaculture, including a treatment box 1, a water inlet pump 2 is installed at one end of the top of the treatment box 1 by screws, the water inlet end of the water inlet pump 2 is fixedly connected to the water inlet pipe 3, and a water outlet pump 4 is installed at the other end of the bottom of the treatment box 1 by screws. An aeration box 5 is placed at one end of the treatment box 1, and the aeration box 5 and the water outlet pump 4 are connected by a water pipe. The bottom end of the aeration box 5 away from the water outlet pump 4 is connected to a detection tube 6 by a thread, and one end of the detection tube 6 is connected to the water outlet pipe 8 by a thread, and one end of the water outlet pipe 8 is fixedly connected to a first electric valve 7.

[0021] The personnel starts the water inlet pump 2 to pump the water inside the breeding pond into the treatment box 1 for water treatment, and simultaneously starts the water outlet pump 4 to allow the water to flow into the aeration box 5 for oxygenation treatment, and then be discharged through the detection tube 6. When the test is qualified, the first electric valve 7 is opened to discharge the water through the outlet pipe 8, so that the water is discharged into the breeding pond.

[0022] like Figure 4As shown, a processing assembly 9 is installed inside the processing box 1, and the processing assembly 9 includes a first filter 901, a purification layer 902 and an activated carbon adsorption layer 903; A first filter screen 901 is slidably connected to the top of the processing box 1, a purification layer 902 is slidably connected to the bottom of the first filter screen 901, and an activated carbon adsorption layer 903 is slidably connected to the bottom of the purification layer 902.

[0023] The first filter screen 901, the purification layer 902 and the activated carbon adsorption layer 903 are slid into the interior of the processing box 1 and fixed by fixing screws. The purification layer 902 includes a placement frame and a suspended ball filler, and the suspended ball filler is placed inside the placement frame. The activated carbon adsorption layer 903 includes a placement box and multiple activated carbon plates, and the placement box and the multiple activated carbons are fixed by screws.

[0024] After the water flow enters the treatment box 1, impurities and particles in the water flow are removed by the first filter mesh 901. The filtered water flow passes through the purification layer 902, and the microorganisms in the water flow are degraded by the purification layer 902. The water flow that passes through the purification layer 902 passes through the activated carbon adsorption layer 903, and the organic matter and pigments in the water flow are adsorbed and treated. By treating the water flow layer by layer, the effect of water flow treatment is improved.

[0025] like Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, an automatic cleaning and collecting assembly 10 is installed inside the processing box 1. The automatic cleaning and collecting assembly 10 includes a motor 1001, a bevel gear connecting mechanism 1002, a rotating shaft 1003, a cleaning rod 1004, an extended spring telescopic column 1005, an extension plate 1006, a driving shaft 1007, a belt connecting mechanism 1008, a rotating frame 1009, a baffle 1010, a leakage hole 1011, a barrier net 1012, a fixed frame 1013 and a second filter net 1014; A motor 1001 is installed on the top of the processing box 1 by screws, and the output shaft of the motor 1001 is fixedly connected to a bevel gear connecting mechanism 1002. The bottom of one end of the bevel gear connecting mechanism 1002 is fixedly connected to a rotating shaft 1003, and the rotating shaft 1003 is rotatably connected to the inside of the processing box 1. A cleaning rod 1004 is fixedly sleeved on the outer side of the bottom of the rotating shaft 1003, and an extended spring telescopic column 1005 is evenly installed inside the cleaning rod 1004 by screws. An extension plate 1006 is installed on one end of the extended spring telescopic column 1005 by screws, and a leakage hole 1011 is opened at one end of the top surface of the first filter screen 901.

[0026] An arc corner is provided at the end of the extension plate 1006, and the extension plate 1006 is slidably connected to the inside of the cleaning rod 1004. The bottom surface of the cleaning rod 1004 and the bottom surface of the extension plate 1006 are in the same horizontal plane. The bottom surface of the extension plate 1006 is in contact with the top surface of the first filter screen 901, thereby cleaning the top surface of the first filter screen 901, allowing impurities to leak out through the leakage hole 1011, and facilitating the cleaning of different positions on the top surface of the first filter screen 901, facilitating the movement of the extension plate 1006, and avoiding the problem of the extension plate 1006 getting stuck when moving.

[0027] The bevel gear connection mechanism 1002 includes two bevel gears, which are meshed and connected. The output shaft of the motor 1001 and the end of the rotating shaft 1003 are fixedly connected with bevel gears. The rotation of one bevel gear is realized by the rotation of the output shaft of the motor 1001, and the meshing connection of the two bevel gears is realized to realize the connection of another bevel gear, thereby driving the rotating shaft 1003 to rotate.

[0028] The processing box 1 is internally rotatably connected to a driving shaft 1007, the top of the driving shaft 1007 is connected to the rotating shaft 1003 via a belt connection mechanism 1008, a rotating frame 1009 is fixedly sleeved on the outside of the bottom of the driving shaft 1007, a baffle 1010 is evenly welded inside the rotating frame 1009, and a barrier net 1012 is evenly rotatably connected to the bottom of the rotating frame 1009, a fixed frame 1013 is installed on the outside of the processing box 1 by screws, and a second filter net 1014 is installed inside the fixed frame 1013 by screws.

[0029] A fixed plate is installed at the bottom of the rotating frame 1009 inside the processing box 1 by screws, and the barrier net 1012 corresponds to the leakage hole 1011, which is convenient for limiting the barrier net 1012 inside the processing box 1 to prevent the barrier net 1012 from rotating inside the processing box 1, and facilitates impurities on the top of the first filter net 901 to enter the rotating frame 1009 and block the impurities through the horizontal barrier net 1012.

[0030] A closed door is hinged at one end of the fixed frame 1013, and the bottom surface of the closed door is at the same horizontal plane as the bottom surface of the second filter screen 1014. One end of the bottom of the fixed frame 1013 is connected to the water inlet pipe 3 through a connecting pipe, which is convenient for cleaning impurities on the top of the second filter screen 1014, and allows the water flow entering the fixed frame 1013 to enter the treatment box 1 again through the suction of the water inlet pump 2.

[0031] During the water filtering process, the motor 1001 is turned on, and the rotating shaft 1003 is driven to rotate through the connection of the bevel gear connecting mechanism 1002. At this time, the cleaning rod 1004, the extended spring telescopic column 1005 and the extension plate 1006 are rotated by the rotation of the rotating shaft 1003, so as to clean the impurities on the top of the first filter 901 and push the impurities to move, so that the impurities enter the interior of the rotating frame 1009 through the leakage hole 1011. The baffle 1010 can prevent a large amount of water from passing through the interior of the rotating frame 1009, thereby cleaning the impurities on the top of the first filter 901 and avoiding the problem that impurities accumulate on the top and cause poor permeability of the first filter 901, resulting in low water treatment efficiency. At the same time, the shaft 1007 is driven to rotate by the connection of the belt connection mechanism 1008, and the rotation of the driving shaft 1007 drives the rotating frame 1009 to rotate, and then drives the barrier net 1012 to rotate. Since the cleaning rod 1004 and the extension plate 1006 will push the impurities on the top of the first filter screen 901 to the top of the barrier net 1012, as the rotating frame 1009 rotates, a barrier net 1012 inside the processing box 1 can be gradually rotated to the outside of the processing box 1, and at the same time, a barrier net 1012 outside the processing box 1 can be gradually rotated to the inside of the processing box 1, After the isolation net 1012 is completely rotated to the outside of the treatment box 1, the other barrier net 1012 will be completely rotated to the inside of the treatment box 1. At this time, the barrier net 1012 will rotate due to gravity because there is no support at the bottom. At this time, the impurities on the top of the barrier net 1012 will fall into the fixed frame 1013, and the impurities will be collected by the fixed frame 1013 and filtered by the second filter net 1014. The water flow enters the bottom of the fixed frame 1013. At this time, the water flow can be continued to be pumped into the interior of the treatment box 1 through the water inlet pump 2 to achieve the cleaning of impurities and automatic collection of the cleaned impurities.

[0032] like Figure 2 、 Figure 8 and Figure 9 As shown, a selective aeration assembly 11 is provided inside the oxygen enrichment box 5, and the selective aeration assembly 11 includes a flat gear connection mechanism 1101, a fan blade 1102, an air inlet pipe 1103, an aeration pipe 1104, an air outlet pipe 1105, a closed spring telescopic column 1106, a closed ball 1107, a baffle 1108, a floating plate 1109, a closed frame 1110, a closed electric telescopic column 1111 and a sealing frame 1112; A flat gear connecting mechanism 1101 is provided on the top of the processing box 1, and a fan blade 1102 is fixedly connected to one end of the top of the flat gear connecting mechanism 1101. An air inlet pipe 1103 is installed on the top of the processing box 1 by screws. An aeration pipe 1104 is fixedly connected to the bottom end of the air inlet pipe 1103 at a position away from one end of the fan blade 1102. An air outlet pipe 1105 is welded to one end of the outer side of the air inlet pipe 1103. A closed spring telescopic column 1106 is installed inside one end of the air outlet pipe 1105 by screws, and a closed ball 1107 is bonded to one end of the closed spring telescopic column 1106. The flat gear connection mechanism 1101 includes a large gear and a small gear, and the gear ratio of the large gear to the small gear is 4:1. The large gear and the small gear are both rotatably connected to the top of the processing box 1, and the large gear is meshed with the small gear. The large gear is fixedly sleeved on the outside of the rotating shaft 1003, and the top of the processing box 1 is rotatably connected. The small gear is fixedly sleeved on the outside of the fixed shaft, and the fan blade 1102 is fixedly sleeved on the top of the fixed shaft. The fan blade 1102 is inside one end of the air inlet pipe 1103, so that the rotation speed of the small gear is greater than that of the large gear, thereby causing the fixed shaft to rotate quickly, and causing the fan blade 1102 to rotate quickly, thereby diverting the external wind into the inside of the air inlet pipe 1103.

[0033] The aeration pipe 1104 is fixedly installed inside the oxygenation box 5, and aeration ports are evenly opened on the outside of the aeration pipe 1104. The outer diameter of the closing ball 1107 is larger than the inner diameter of the air outlet pipe 1105, which is convenient for closing the end of the air outlet pipe 1105, and the water flow inside the oxygenation box 5 can be aerated through the aeration pipe 1104.

[0034] A barrier plate 1108 is welded inside the aeration box 5, a floating plate 1109 is slidably connected to the outside of the aeration pipe 1104, a closed frame 1110 is installed at the bottom of the floating plate 1109 by screws, a closed electric telescopic column 1111 is installed at the top of the aeration box 5 by screws, and a sealing frame 1112 is installed at the bottom of the closed electric telescopic column 1111 by screws.

[0035] The closing frame 1110 includes a connecting rod and multiple closing cylinders. The outside of the aeration tube 1104 is slidably connected to a closing cylinder on the outside of the aeration port. The multiple closing cylinders are connected by connecting rods. One of the closing cylinders is fixedly connected to the floating plate 1109 by the connecting rod, which is convenient for closing the aeration port. The closing cylinder can be driven to move to open the aeration port according to the water height, and it is convenient to drive multiple closing cylinders to move synchronously.

[0036] Water outlets are provided between the baffle plate 1108 and the upper and lower inner walls of the oxygenation box 5. The two water outlets are of the same size. The end face of the sealing frame 1112 is in contact with the end face of the baffle plate 1108. The sealing frame 1112 includes two closing plates and two rectangular rods. A closing plate is installed at the bottom of the closed electric telescopic column 1111 by screws. Rectangular rods are installed at both ends of the bottom of a closing plate by screws. The bottoms of the two rectangular rods are connected by another closing plate. The outer diameter of the rectangular plate is larger than the inner diameter of the water outlet, which facilitates the discharge of water from different positions.

[0037] According to actual conditions, personnel open and close the electric telescopic column 1111, drive the sealing frame 1112 to move, and when aeration is needed, the bottom end of the baffle plate 1108 is closed, and the water flows into the interior of the aeration box 5. The water flows gradually rise inside the aeration box 5, and the water flows to drive the floating plate 1109 to move upward. The movement of the floating plate 1109 drives the closing frame 1110 to move and open the aeration port. When the rotating shaft 1003 rotates, it is connected through the flat gear connecting mechanism 1101 to drive the fan blade 1102 to rotate, and the external wind is drawn into the air inlet pipe 1103. The wind enters the aeration pipe 1104 through the air inlet pipe 1103 and is discharged through the aeration port to aerate the water flow. After aeration, the water flow passes through the top of the baffle plate 1108 and flows down to be discharged. In this process, the wind is discharged through the aeration port, the closing spring telescopic column 1106 is compressed, and the closing ball 1107 closes the air outlet pipe 1105. When there is no need to aerate the water flow, personnel open the closed electric telescopic column 1111, drive the sealing frame 1112 to move, and close the top of the baffle 1108. At this time, the water flows into the aeration box 5 and is directly discharged from the bottom of the baffle 1108. At this time, the float 1109 falls due to gravity, driving the closing frame 1110 to move, closing the aeration port, and not aerating the water flow. The wind entering the air inlet pipe 1103 will push the closing ball 1107 due to the closure of the aeration port, causing the closing spring telescopic column 1106 to stretch, opening the air outlet pipe 1105, and the air is discharged from the air outlet pipe 1105. The water is aerated as needed, and no additional electrical components are required to realize the aeration function, thereby reducing the use cost of the water purification device.

[0038] like Figure 3 and Figure 10 As shown, a detection reflux component 12 is installed inside the detection tube 6, and the detection reflux component 12 includes a pH value detection component 1201, a dissolved oxygen detection component 1202, a turbidity detection component 1203, a second electric valve 1204, and a reflux pipe 1205; A pH value detection component 1201 is provided inside the detection tube 6, a dissolved oxygen detection component 1202 is provided at one end of the detection tube 6 near the pH value detection component 1201, a turbidity detection component 1203 is provided at one end of the detection tube 6 near the dissolved oxygen detection component 1202, a second electric valve 1204 is provided at one end of the top of the detection tube 6, the top of the second electric valve 1204 is connected to a return pipe 1205 through a thread, and the other end of the return pipe 1205 is connected to the top of the treatment box 1 through a thread.

[0039] The pH value detection component 1201 includes a pH sensor and a pH value transmission module, the dissolved oxygen detection component 1202 includes a dissolved oxygen sensor and a dissolved oxygen value transmission module, and the turbidity detection component 1203 includes a turbidity sensor and a turbidity value transmission module. One end of the pH sensor, dissolved oxygen sensor and turbidity sensor are all inside the detection tube 6, and the pH value transmission module, dissolved oxygen value transmission module and turbidity value transmission module are fixedly installed on the outside of the detection tube 6. The pH value transmission module, dissolved oxygen value transmission module and turbidity value transmission module are wirelessly connected to an external display screen, which is convenient for personnel to view the detected values ​​in time and detect and process the water flow.

[0040] After the water is treated and aerated by the treatment box 1 and the oxygenation box 5, the water flows into the detection tube 6, and the water flow is detected by the pH value detection component 1201, the dissolved oxygen detection component 1202 and the turbidity detection component 1203. The personnel observes through the display screen. When the test is qualified, the personnel opens the first electric valve 7 to allow the water to be discharged into the breeding pond through the outlet pipe 8. When the test result is unqualified, the personnel opens the second electric valve 1204 to allow the water to enter the treatment box 1 again through the return pipe 1205 and be circulated again to ensure the effect of water treatment and thus ensure the quality of aquaculture.

[0041] like Figure 4 and Figure 5 As shown, an extrusion assembly 13 is provided at one end of the bevel gear connection mechanism 1002. The extrusion assembly 13 includes a driving rod 1301, a rubber tube 1302, a threaded rod 1303 and an extrusion member 1304. One end of a bevel gear is fixedly connected to a driving rod 1301, and one end of the driving rod 1301 is embedded and rotatably connected to a threaded rod 1303 through a T-block. A rubber tube 1302 is bonded to the outside of one end of the driving rod 1301, and an extrusion piece 1304 is provided on the outside of the threaded rod 1303. The rubber tube 1302 is inside one end of the threaded rod 1303.

[0042] The extrusion piece 1304 includes multiple extrusion plates and connecting screws. The ends of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 are all provided with extrusion plates. Two adjacent extrusion plates are connected by a connecting screw. A connecting rod is connected to the outside of the threaded rod 1303 by a thread. The connecting rod on the outside of the threaded rod 1303 is connected to the extrusion plate at the end of the first filter 901 through a connecting screw. The movement of the connecting rod is achieved by rotating the threaded rod 1303, and then the movement of the extrusion plate is achieved. A rubber plate is bonded to the end face of the extrusion plate, and the end faces of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 are extruded to ensure the stability of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 during use. In addition, multiple extrusion plates are connected by connecting screws to facilitate the subsequent disassembly of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903.

[0043] When the bevel gear connection mechanism 1002 rotates, it drives the driving rod 1301 to rotate. At this time, the friction between the rubber tube 1302 and the threaded rod 1303 drives the threaded rod 1303 to rotate. The threaded rod 1303 is connected to the extrusion piece 1304 through a thread. When the threaded rod 1303 rotates, the extrusion piece 1304 is driven to move. The movement of the extrusion piece 1304 squeezes the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903, ensuring the stability of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 during use, and better For water treatment, during the process of the extrusion piece 1304 squeezing the first filter screen 901, the purification layer 902 and the activated carbon adsorption layer 903, since the force on the end of the extrusion piece 1304 is greater than the friction between the rubber tube 1302 and the threaded rod 1303, the rotation of the driving rod 1301 will not drive the threaded rod 1303 to rotate, and the axial pressure can be continuously applied to the threaded rod 1303 to avoid the problem of loosening of the extrusion piece 1304, thereby continuously squeezing the first filter screen 901, the purification layer 902 and the activated carbon adsorption layer 903 to ensure the effect of water treatment.

[0044] Personnel pass water into the treatment box 1 through the water inlet pump 2, and the water flows through the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 in sequence to achieve water treatment. At the same time, the water outlet pump 4 and the motor 1001 are turned on to make the water inside the treatment box 1 enter the aeration box 5. Personnel select different water outlets according to actual conditions. If the water is discharged from the top of the aeration box 5, aeration treatment is performed. If the water is discharged from the lower end of the aeration box 5, no aeration treatment is performed. The discharged water is tested by the detection tube 6. If the test is qualified, the first electric valve 7 is opened, and the water is discharged into the aquaculture pond again through the outlet pipe 8 to achieve water circulation purification inside the aquaculture pond. If the water fails the test, the second electric valve 1204 is opened to make the water enter the treatment box 1 again for further treatment until it is qualified. During the water flow treatment process, impurities on the top of the first filter 901 can be automatically cleaned and collected to ensure the permeability of the first filter 901, thereby ensuring the efficiency of water flow filtration and purification. No manual cleaning is required, which reduces the labor intensity of personnel. At the same time, the external wind is introduced into the oxygenation box 5 through the operation of the motor 1001 to aerate the water flow, thereby achieving consistency in water treatment purification and aeration, and ensuring the effect of water purification. In addition, during the water purification process, pressure can be continuously applied to the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 to ensure the stability of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 during use, and to avoid shaking of the first filter 901, the purification layer 902 and the activated carbon adsorption layer 903 during use, which may cause water leakage and ensure the effect of water purification.
