[0031] Working principle:

[0032] When using the utility model, water is first stored in the culture pond body 1. When storing water, the valve 12 is first closed. Then water is simultaneously injected into the culture pond body 1 through the two water inlet pipes 16. Since the two water inlet pipes 16 are inclined downward and in opposite directions, the water in the culture pond body 1 will form a vortex centered at the center of the culture pond body 1.

[0033] Then, the fry is placed in the culture pond body 1 filled with water, and then the valve 12 is opened. Water is injected into the culture pond body 1 through the water inlet pipe 16, and the water in the culture pond body 1 is discharged through the drain pipe 17, thereby forming a water cycle.

[0034] The impurities such as residual bait and feces in the breeding pond body 1 are gathered at the center of the breeding pond body 1 under the drive of the vortex. The impurities enter the filter tube 18 through the filter hole 19, while the fry cannot pass through the filter hole 19. After entering the filter tube 18, the impurities enter the sewage storage tank 2 through the sewage pipe 11. Then the water pump 9 is started, and the water pump 9 pumps the sewage and impurities in the sewage storage tank 2 into the filter box 3 through the pumping pipe 10 and the water inlet 4. The water flows through the filter plate 6, and the impurities remain on the filter plate 6. The sewage is transported to the external sewage purification system through the outlet 5.

[0035] When there are a lot of impurities accumulated on the filter plate 6, temporarily turn off the water pump 9, then open the switch door, pull out the filter plate 6 from the filter box 3 and replace it with a new filter plate 6. When installing the filter plate 6 in the filter box 3, just put the card strip 8 on the top of the bar card block 7, and the disassembly process of the filter plate 6 is simple and convenient.

[0036] At this point, along with the water circulation in the breeding pond body 1, the impurities in the breeding pond body 1 are automatically discharged from the breeding pond body 1, the cleaning efficiency is high, and the manpower consumption is reduced.

[0037] After the sewage storage tank 2 has been used for a long time, some impurities may remain in the sewage storage tank 2 and not be extracted. The pull rod 14 is pulled upward by the pull block 15 to remove the sieve plate 13 from the sewage storage tank 2. The impurities in the sewage storage tank 2 that have not been extracted can be cleaned.

[0038] After the filter tube 18 has been used for a long time, some impurities will adhere to the outer wall of the filter tube 18 and block the filter hole 19. At this time, the motor 23 is started, and the output shaft of the motor 23 rotates to drive the first shaft 30 to rotate. The first shaft 30 drives the driving gear 32 to rotate. The driving gear 32 drives the driven gear 33 to rotate. The driven gear 33 drives the second shaft 31 to rotate. The second shaft 31 drives the driving wheel 24 to rotate. The driving wheel 24 drives the driven wheel to rotate through a belt. The driven wheel drives the rotating tube 27 to rotate on the center rod 21. The rotating tube 27 drives the rotating disk 26 to rotate on the center rod 21. The rotating disk 26 drives the scraper rod 28 to rotate around the filter tube 18. The scraper rod 28 scrapes off the impurities adhering to the outer wall of the filter tube 18 and cleans the outer wall of the filter tube 18, thereby preventing the impurities from blocking the filter hole 19.
