[0030] See also Figure 1-5The utility model provides a technical solution: an aquaculture box with internal circulating water, comprising a feeding box 1 and a circulating pipeline assembly, wherein the circulating pipeline assembly comprises a drain pipe 2 with one end penetrating through the bottom side wall of the feeding box 1, a first filter screen 3 is installed at one end of the drain pipe 2 located inside the feeding box 1, and a second filter screen 4 is detachably installed at the other end located outside the feeding box 1, the first filter screen 3 can isolate the organisms cultured in the feeding box 1, and the second filter screen 4 can filter the excrement and residual feed of the fish.

[0031] The circulation pipeline assembly also includes a connecting pipe 5 located directly below the drain pipe 2, one end of the connecting pipe 5 is facing upward and can receive the water flowing out of the drain pipe 2, and the other end is connected to a water pump 6, the output end of the water pump 6 is connected to a water inlet pipe 7, and one end of the water inlet pipe 7 extends into the breeding box 1.

[0032] In this solution: the feeding box 1 is fixedly connected to the drain pipe 2, and the outlet of the drain pipe 2 inside the feeding box 1 is flush with the inner wall of the feeding box 1. This can reduce the amount of fish excrement and residual feed accumulated on the side wall of the drain pipe 2. The outlet of the drain pipe 2 outside the feeding box 1 faces downward, so that the water flows vertically downward into the connecting pipe 5. The diameter of the connecting pipe 5 is larger than the diameter of the drain pipe 2, which can reduce the loss of water flow. After the water pump 6 is connected to an external power supply, the water flows into the feeding box 1 through the water inlet pipe 7, realizing the internal circulation of the water flow. The optional model of the water pump 6 is: ISG25-125.

[0033] When in use, the fish excrement and residual feed are discharged from the aquaculture box through the drain pipe 2 in the water flow, and the fish excrement and residual feed are collected at the second filter 4. When a certain amount of fish excrement and residual feed accumulates at the second filter 4, the second filter 4 is removed from the drain pipe 2, and the second filter 4 is installed on the drain pipe 2 after cleaning. Compared with the prior art, the cleaning of fish excrement and residual feed is more convenient.

[0040] In this embodiment, the third filter screen 10 is connected to a first gauze screen 13 , and the first gauze screen 13 covers the entire third filter screen 10 .

[0041] In this solution, by setting the first gauze 13 on the third filter 10, the first gauze 13 covers the entire third filter 10, which can further filter out tiny debris that are not filtered out by the second filter 4 and the third filter 10, making the water quality cleaner.

[0042] In this embodiment, a second gauze 14 is provided at the inlet end of the connecting tube 5 , and the second gauze 14 covers the tube opening of the connecting tube 5 .

[0043] In this solution, a second gauze 14 is provided at the inlet end of the connecting pipe 5 , and the second gauze 14 covers the pipe opening of the connecting pipe 5 , thereby further filtering out debris and preventing the debris from entering the connecting pipe 5 and accumulating to block the water pump 6 .

[0044] In this embodiment: the second filter screen 4 is in the shape of a net bag.

[0045] In this solution, by configuring the second filter 4 to be in the shape of a net bag, the second filter 4 can collect more fish excrement and residual feed at a time, thereby reducing the number of times the second filter 4 needs to be cleaned, and further improving the work efficiency of the staff.

[0046] In this embodiment: an impeller 15 is installed at the opening of the second filter screen 4, and the impeller 15 can rotate under the impact of water flow.
