Description

Technical Field

[0001] This invention relates to the field of fish farming technology, specifically to a multi-stage water circulation filtration device for grass carp fry breeding. Background Technology

[0002] Grass carp are fish belonging to the genus *Cyprinus* of the family Cyprinidae. They are mainly distributed in the Yangtze River and Pearl River systems and their associated lakes, reservoirs, and ponds in China. They generally prefer to live in the middle and lower layers of the water and in areas with abundant aquatic plants near the shore. During the fry stage, they feed on zooplankton, while during the juvenile stage, they also eat insects, earthworms, algae, and duckweed. In the process of breeding grass carp fry, it is necessary to circulate and filter the water in the breeding pond to ensure water quality and improve the stability of the breeding environment. The filtration steps mainly include physical filtration, biological filtration, sterilization and disinfection, oxygenation and temperature control, and water quality monitoring.

[0003] The patent application with application number CN202121468834.7 mentions a "filtration device and fish fry hatching pond". The patent uses a filter screen that is fully covered on a sliding frame. The filter screen is permeable to water and prevents fish eggs from passing through. The sliding frame is made of corrosion-resistant material, and the outer edge of the sliding frame is used to slide and connect with the inner wall of the filter tank in the fish fry hatching pond. The sliding frame can slide to detach from the filter tank. The filtration device is not easily deformed and is easy to disassemble, thereby improving the hatching efficiency of the fish fry hatching pond.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] 1. Equipped with multi-stage processing components, the inlet and outlet electric actuators drive the inlet and outlet sealing frame and separation screen barrel to move. Water is injected into the separation screen barrel in conjunction with the injection linkage pipe and injection pump. The separation screen barrel is rotated by the shift motor, which rotates the water and large particle impurities. Water is continuously drained in conjunction with the drainage linkage pipe. Air is continuously injected into the fixed aeration tank by the treatment pump and the multi-hole jet pipe frame. The suspended impurities in the water are removed by the aeration and the mixed impurities in the water are separated from the water. The two-step continuous sludge removal process ensures that large and small particles and suspended impurities in the water are steadily removed, improving the water purification effect. Furthermore, the flow treatment improves the treatment efficiency.

[0039] The electric actuator drives the closing operation frame and the fixed filter element to be inserted into the filtration tank. The fixed filter element is steadily inserted into the filtration tank and intercepts and filters out fine particles and some bacteria in the water. The temperature of the gas mixing tank is controlled by the condenser and temperature controller. Ozone and oxygen are injected into the water by the ozone generator, oxygen pump and injection operation pipe respectively. Ozone sterilization and algae removal are carried out and oxygen is added to the water to achieve steady water cleaning.

[0040] Through screening and separation, aeration and separation, filter cartridge interception and absorption, ozone mixing sterilization and oxygenation mixing treatment, multiple operation steps work together to improve the effect and efficiency of water purification. At the same time, the simultaneous operation of inlet water switching and multi-component continuous processing, and the circulation coordination, improve the filtration speed. Furthermore, the use of electric push rods for direct handling increases the speed of equipment handling, thereby enabling quick completion of internal sludge cleaning, reducing the labor intensity of maintenance personnel and reducing the time required for water filtration.

[0041] 2. Equipped with a mixing and collection component, the collection net box is magnetically fixed by an electromagnet. A lifting hydraulic cylinder, switching motor, and switching linkage frame work together to raise and lower the collection net box, placing it into the fixed aeration tank. Alignment rails, alignment scrapers, and slag-pushing rails drive the alignment scraper to push impurities from the water surface into the inside of the collection net box, achieving steady slag removal. A flipping motor and flipping sealing cover seal the collection net box, ensuring steady slag removal and collection, preventing continuous accumulation of impurities from affecting drainage stability. Disinfectant is added to the collection relay box through a feeding fixed bucket. A mixing motor drives the mixing frame to rotate, mixing the water and disinfectant for sterilization. This ensures effective and efficient water filtration during water purification.

[0042] In summary, by combining multi-stage treatment components and mixing components, and through multiple sets of purification treatments, sludge removal and collection, sludge scraping and collection, and mixing treatment, rapid and continuous water treatment can be achieved, improving the water filtration effect and efficiency, and ensuring the quality of the treated water.

[0081] The working principle and usage process of this invention are as follows: When filtering the water in the grass carp fry breeding pond, the inlet / outlet electric actuator 205 drives the inlet / outlet sealing frame 206 and the separation net bucket 208 to slide into the inner side of the interception and limiting bucket 203, so that the inlet / outlet sealing frame 206 fits into the interception and limiting bucket 203, and the separation net bucket 208 fits into the interception and limiting bucket 203. Water in the pond is drawn by the injection pump 225 through the injection linkage pipe 224 and injected into the inner side of the separation net bucket 208. The shifting motor 207 drives the separation net bucket 208 to rotate along the inlet / outlet sealing frame 206, driving the water and grass carp fry to rotate. The rotating particulate impurities separate water into the interception and limiting barrel 203 and inject it into the fixed aeration tank 201 through the discharge linkage pipe 204. When the fixed aeration tank 201 is filled with liquid, the treatment pump 210 and the multi-hole jet pipe frame 209 continuously inject air into the fixed aeration tank 201. The suspended impurities in the water are discharged by the aeration and the mixed impurities in the water are separated from the water, realizing steady sludge removal treatment. The water flows along the interception and limiting barrel 203 to the position of the external discharge fixed pipe 222, realizing two-step continuous sludge removal treatment and ensuring the efficiency of sludge removal treatment of impurities in the water.

[0082] During the aeration process, the collection net box 305 is magnetically fixed to the bottom of the switching linkage frame 303 by connecting the electromagnet 304. The lifting hydraulic cylinder 301 drives the switching motor 302 and the switching linkage frame 303 to rise. The switching motor 302 drives the switching linkage frame 303 to rotate, so that the collection net box 305 is aligned with the position of the fixed aeration tank 201. At this time, the lifting hydraulic cylinder 301 drives the switching motor 302 and the switching linkage frame 303 to move down, thereby inserting the collection net box 305 into the inside of the fixed aeration tank 201. At the same time, the alignment electric slide rail 310 drives the alignment scraper 311 to move down and insert into the inside of the fixed aeration tank 201. The slag pushing electric slide rail 308 drives the slag pushing linkage block 309 and the alignment scraper 311 to move. The alignment scraper 311 pushes the impurities on the water surface into the inside of the collection net box 305, realizing steady slag removal.

[0083] The external discharge pipe 222 is opened by the treatment valve 223, allowing the aerated water to be discharged into the collection relay box 211. At this time, disinfectant is added into the collection relay box 211 through the feeding fixed bucket 314. The mixing motor 312 drives the mixing frame 313 to rotate, mixing the water and disinfectant for sterilization. Then, the fixed filter element 215 is inserted into the side of the closing operation frame 214. The opening / closing electric actuator 213 moves the closing operation frame 214 and the fixed filter element 215 into the filtration treatment bucket 212. The fixed filter element 215 is steadily inserted into the filtration tank 212. Disinfected water is drawn into the filtration tank 212 by the injection linkage pipe 224 and the injection pump 225. The disinfected water gradually rises through the fixed filter element 215 within the filtration tank 212 for continuous filtration, intercepting fine particles and further purifying the water. The purified water then flows through the external discharge fixed pipe 222 into the air-mixing treatment tank 216. At this point, the condenser 217 cools the water to 20°C. Then, ozone is injected into the gas-mixing treatment tank 216 via the ozone generator 220 and injection operation pipe 219. The mixing motor 312 drives the mixing frame 313 to mix the water and ozone, achieving ozone sterilization and algae removal. The treated water is then injected into the inner side of the second gas-mixing treatment tank 216 via the injection linkage pipe 224 and injection pump 225. At this time, the temperature control processor 218 raises the water temperature to 40°C, coordinating with the mixing motor... 312 drives the mixing rack 313 to agitate the water, causing ozone to decompose into oxygen, thus achieving ozone cleaning treatment. The treated water is injected into the third gas mixing treatment tank 216 through the injection linkage pipe 224 and the injection pump 225. Oxygen is injected into the gas mixing treatment tank 216 by the oxygenation pump 221 and the injection operation pipe 219. The temperature control processor 218 controls the water temperature at 27°C to achieve steady water treatment. The water is returned to the breeding pond through the external discharge fixed pipe 222 to ensure continuous purification and continuous water supply treatment.
