Example 2

As shown in fig. 1, 2, 3, 4, 5, 6, 7 and 10, in the separation type water circulation purification system for a fish tank described in embodiment 1, the separation device 11 includes a filtering pipe 111, a separating pipe 112 and a water outlet pipe 113 which are vertically arranged and sequentially sleeved from outside to inside, the top surfaces of the water outlet pipe 113 and the separating pipe 112 are lower than the top surface of the filtering pipe 111, the water outlet pipe 113 and the first partition plate 161 are hermetically arranged, the separating pipe 112 is matched with the first annular

outer wall

162, 1111 for communicating the filtering pipe 111 inside and outside is arranged at the bottom of the filtering pipe 111, and water in the fish tank 2 is discharged from the fish tank 2 through the water outlet pipe 113.

The filter pipe 111, the separating pipe 112 and the water outlet pipe 113 are sequentially sleeved from outside to inside, the water outlet pipe 113 plays a role in draining water, 1111 used for communicating the inside and the outside of the filter pipe 111 is arranged at the bottom of the filter pipe 111, and water in the fish tank 2 enters the water outlet pipe 113 through the top surface of the water outlet pipe 113;

when the fish tank is in operation, the top surface of the water outlet pipe 113 is lower than the top surface of the filter pipe 111, and the top surface of the water outlet pipe 113 is lower than the water surface in the fish tank 2, so that the water in the filter pipe 111 and the water outside the separation pipe 112 have a liquid level difference, a suction force towards the inside of the filter pipe 111 is generated at 1111, and the water outside the filter pipe 111 and the fish feces 5 are sucked into the filter pipe 111 through 1111;

moreover, as the separating pipe 112 is matched with the first annular outer wall 162, and the water in the separating pipe 112 is closest to the water outlet pipe 113, most of the water discharged into the water outlet pipe 113 comes from the separating pipe 112, and an upward suction force is formed in the separating pipe 112 due to the difference between the liquid levels inside and outside the filtering pipe 111, so that the suction force towards the first sewage discharging cavity 165 is formed at the second sewage discharging port 1621, and the water and the fish feces 5 entering the filtering pipe 111 are sucked into the first sewage discharging cavity 165 through the second sewage discharging port 1621;
