[0024] Embodiment 1:

[0025] Refer to Figures 1-3, A filtration and purification device for cultivating marine fish with brackish water, comprising a bracket 1. A water tank 2 is arranged on the bracket 1. A sealing cover 21 is arranged on the top of the water tank 2. An inlet is arranged on the upper side wall of the water tank 2 and is connected to a water inlet pipe 22. A valve 23 is arranged on the water inlet pipe 22. A drain port is arranged on the bottom side wall of the water tank 2 and is connected to a drain pipe 24. A first egg-shaped branch pipe 25 is vertically arranged on the bracket 1 on one side of the water tank 2. An aeration head 20 is arranged inside the lower end of the first egg-shaped branch pipe 25. The aeration head 20 is connected to an air pump arranged on the bracket 1 outside the water tank 2 through an air pipe for air supply. A second egg-shaped branch pipe 26 is obliquely arranged at the upper end of the first egg-shaped branch pipe 25. A third egg-shaped branch pipe 27 is vertically arranged at the upper end of the second egg-shaped branch pipe 26. The lower end of the first egg-shaped branch pipe 25 is connected and communicated with the drain pipe 24. The lower end of the second egg-shaped branch pipe 26 is connected and communicated with the upper end of the first egg-shaped branch pipe 25. The upper end of the second egg-shaped branch pipe 26 is connected and communicated with the lower end of the third egg-shaped branch pipe 27. A sealing plate 261 is arranged at the upper end of the third egg-shaped branch pipe 27. An exhaust pipe 262 is arranged inside the third egg-shaped branch pipe 27. An air inlet head 263 is arranged at the lower end of the exhaust pipe 262. The upper end of the exhaust pipe 262 extends upward and passes through the sealing plate 261 and extends above the third egg-shaped branch pipe 27. An exhaust elbow 264 is arranged at the upper end of the exhaust pipe 262. An exhaust valve 265 is arranged on the side wall of the upper end of the exhaust pipe 262. A V-shaped pipe 28 is arranged on the side wall of the second egg-shaped branch pipe 26. The first end of the V-shaped pipe 28 is connected to a waste discharge port arranged on the side wall of the second egg-shaped branch pipe 26. A drain elbow 29 is arranged at the second end of the V-shaped pipe 28. A filter box 3 is arranged on the bracket 1 below the drain elbow 29. A liquid inlet 30 is arranged on the top of the filter box 3. A partition 31 is arranged at the bottom inside the filter box 3 to divide the filter box 3 into two water tanks. One water tank is a filtration water tank 32 for containing filtered water, and the other water tank is a impurity water tank 33 for containing impurities. A rotating shaft 34 is arranged above the partition 31. The two ends of the rotating shaft 34 are respectively rotatably connected to the two side walls of the filter box 3. A servo motor 35 for driving the rotating shaft 34 to rotate is arranged on the outer side wall of the filter box 3. One end of the rotating shaft 34 passes through the side wall of the filter box 3 and extends to the outside and is coaxially and fixedly connected to the output shaft of the servo motor 35. Two filter plates 36 are arranged on the two side walls of the rotating shaft 34. By means of the aeration head 20, bubbles are generated in the water in the first egg-shaped branch pipe 25. The bubbles rise through the second egg-shaped branch pipe 26 and the third egg-shaped branch pipe 27 and are discharged from the exhaust pipe 262. Impurities enter the V-shaped pipe 28, which can effectively remove organic substances in the water, prevent them from decomposing in the water body, and can directly adsorb and remove colloids, cellulose, albumin, residual bait, feces and other organic substances from the water, which can ensure the water quality of the breeding water, with high water quality purification efficiency and good purification effect. By introducing the water after protein skimming onto the filter plate 36 for filtration, and then gradually filtering through the filter layer in the filtration water tank 32, the filtered water quality is good. By driving the filter plate 36 to rotate through the servo motor 35 and cleaning the filter plate 36 and the filter cotton 361 through the nozzle 39, the labor intensity is reduced. By irradiating the filter plate 36 and the filter cotton 361 with ultraviolet light, it can prevent the growth of microorganisms on the surface of the filter plate 36 and the filter cotton 361 and prevent blockage.

[0026] In this embodiment, referring to Figure 2 , filter holes are arranged in an array on the surface of the filter plate 36. To increase the filtering effect, a filter cotton 361 is arranged on the filter plate 36, and the large impurities in the brackish water for breeding marine fish can be quickly filtered through the filter cotton 361.

[0027] In this embodiment, referring to Figure 2 , coral bones 37 are arranged at the inner bottom of the filter water tank 32. A filter fleece membrane 371, activated carbon 372, and PP cotton 373 are sequentially arranged above the coral bones 37. A liquid discharge port 321 is arranged at the bottom of the filter water tank 32. The liquid discharged from the liquid discharge port 321 has been completely purified and meets the breeding requirements, and can be directly refluxed into the seawater tank for continued breeding of marine fish. The liquid discharge port 321 is connected to the breeding tank through a pipeline. An impurity outlet 331 is arranged at the bottom of the impurity water tank 33. The impurity water for flushing the filter mesh in the filter water tank 32 is discharged through the impurity outlet 331 for treatment, saving labor costs and eliminating the need for manual cleaning of the filter plate 36 and the filter cotton 361.

[0028] In this embodiment, referring to Figure 2 , an ultraviolet lamp 38 is arranged at the top of the filter box 3. Through the ultraviolet lamp 38, the microorganisms filtered onto the filter plate 36 can be killed to prevent the rapid reproduction of microorganisms from clogging the filter plate 36. A spray head 39 is arranged on the side wall of the filter box 3. The spray head 39 is connected to a water pump through a water pipe to provide high-pressure water, which is directed at the side of the filter mesh for flushing, so that the impurities on the filter plate 36 can be quickly flushed down to prevent clogging of the filter plate 36.

[0029] In this embodiment, referring to Figure 1 , threaded holes are arranged on the sealing plate 261. External threads are arranged on the outer wall of the exhaust pipe 262. The exhaust pipe 262 is internally sleeved in the threaded holes of the sealing plate 261 and is threadedly connected. A sealing ring can also be sleeved on the exhaust pipe 262 to prevent the gas in the third egg-shaped branch pipe 27 from leaking out through the threaded holes.

[0030] In this embodiment, referring to Figure 3, the air inlet head 263 is disc-shaped. A cavity 2631 is arranged inside the air inlet head 263. Air inlet holes 2632 are circumferentially arrayed at the bottom of the air inlet head 263 and are connected to the cavity 2631. An exhaust port 2633 communicating with the cavity 2631 is arranged at the top of the air inlet head. The exhaust port 2633 is connected and communicated with the exhaust pipe 262. Bubbles floating above the liquid surface enter the inside of the cavity 2631 from the air inlet holes 2632 under the gas pressure, then enter the exhaust pipe 262 from the exhaust port 2633, rise along the inner wall of the exhaust pipe 262, and finally are discharged from the drain elbow 29 for collection and treatment. Through the principle of the protein skimmer, organic matter in water can be effectively removed, preventing it from decomposing in the water body. Colloids, cellulose, protein, residual bait, feces and other organic matter can be directly adsorbed and removed from the water, which can ensure the water quality of the aquaculture water and create a good living environment for fish farming.

[0031] As can be seen from the above technical solutions, during use, by controlling the opening of the air pump, gas is conveyed into the aeration head 20, and then the valve 23 is opened. The water in the marine tank is continuously supplied to the water tank 2 through the water pump for purification. The gas is dispersed by the aeration head 20 to generate bubbles in the first egg-shaped pipe 25. The bubbles rise through the first egg-shaped pipe 25, the second egg-shaped pipe 26, and the third egg-shaped pipe 27 in sequence and enter the inside of the exhaust pipe 262, continue to rise along the inner wall of the exhaust pipe 262, and finally are discharged from the drain elbow 29 for collection and treatment. At the same time, when the water level in the water tank 2 after passing through the bubble skimmer is relatively high, through the principle of siphon, the water containing impurities in the V-shaped pipe 28 automatically drains into the filter tank 3 for further filtration and purification when the water level reaches a certain height. Then, more skimmer water continues to enter the V-shaped pipe 28 and waits to enter the filter tank 3 after the water level rises. The water entering the filter tank 3 is filtered by the filter plate 36 and the filter cotton 361, and then is gradually filtered through the filter layer in the filter water tank 3. At the same time, the ultraviolet lamp 38 continuously irradiates the filter plate 36 and the filter cotton 361 to kill the microbial bacteria on their surfaces, preventing a large number of them from multiplying and clogging the filter screen. The filter plate 36 is driven by the servo motor to rotate above the impurity water tank 33, and after the water is pressurized by the water pump, it is sprayed through the nozzle to clean the filter plate 36 and the filter cotton 361, preventing the filter plate 36 and the filter cotton 361 from being clogged.
