DETAILED DESCRIPTION

[0018] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] The utility model provides Figure 1-3 The fish tank for cleaning solid pollutants shown in the figure comprises a tank body, one side of which is divided into a breeding area 20, a water turning area 30, a solid pollutant treatment area 40 and a water collection area 50 by a first partition 11, a second partition 12 and a third partition 13. Figure 1The first partition 11 is located between the breeding area 20 and the water turning area 30 and the water collection area 50, the second partition 12 is located between the solid pollutant treatment area 40 and the water turning area 30, and the third partition 13 is located between the water collection area 50 and the solid pollutant treatment area 40 and the water turning area 30. The water turning area 30, the solid pollutant treatment area 40 and the water collection area 50 are usually located on one side of the breeding area 20.

[0020] The breeding area 20 is the main activity area of ​​the fish, and the solid pollutants such as fish feces and food residues produced by the fish gradually deposit on the bottom of the breeding area 20. The height of the second partition 12 is lower than that of the first partition 11, and the first partition 11 is provided with a water outlet 111 at the bottom of the area between the water turning area 30 and the breeding area 20. Under the condition that new water is continuously added to the breeding area 20, the water in the breeding area 20 can carry the solid pollutants at the bottom of the breeding area 20 from the water outlet 111 into the water turning area 30, and flow into the solid pollutant treatment area 40 from the top of the water turning area 30 under the action of water pressure. The top of the area between the water turning area 30 and the breeding area 20 of the first partition 11 is also provided with an overflow port 112 to prevent the water level in the breeding area 20 from being too high, and the height of the second partition 12 is lower than the overflow port 112.

[0021] The solid pollutant treatment area 40 is divided into a buffer area 41, a water flow area 42 and a sedimentation area 43 arranged in sequence from top to bottom by the fourth partition 14 and the fifth partition 15. In this embodiment, the height of the fourth partition 14 is lower than the second partition 12, so as to expand the volume of the buffer area 41; in other embodiments, the fourth partition 14 can be at the same height as the upper surface of the second partition 12. The buffer area 41 is connected to the top of the water transfer area 30.

[0022] The water flow area 42 is connected to the water collection area 50. The water flow area 42 is provided with a plurality of filter cartridges 421. The filter cartridges 421 are connected to the buffer area 41 and the sedimentation area 43. The filter cartridges 421 have filter screens on their walls. The filter screens can be made of steel wire mesh. After being blocked, they can be removed and cleaned. A discharge port 431 is provided at the bottom of the sedimentation area 43. A valve is provided at the discharge port 431. A pressure relief port 432 connected to the water collection area 50 is provided at the top of the sedimentation area 43. An inclined baffle plate 433 is provided between the pressure relief port 432 and the filter cartridges 421.

[0023] The wall of the filter cartridge 421 is a filter screen. After the solid pollutants are filtered out by the filter cartridge 421, part of the water entering the buffer zone 41 enters the water flow zone 42, and then flows into the water collection zone 50 and is discharged from its drain outlet 51; the other part of the water carries the solid pollutants into the sedimentation zone 43, and the solid pollutants gradually fall to the bottom of the sedimentation zone 43 through the baffle plate 433. The valve of the discharge port 431 at the bottom of the sedimentation zone 43 is kept closed, and the solid pollutants are opened to discharge them after accumulating to a certain thickness. The water entering the sedimentation zone 43 overflows from the pressure relief port 432 at the top to the water collection zone 50. If there is no pressure relief port 432, the solid pollutants are easily backwashed back to the filter cartridge and the buffer zone, and are not easy to settle. The baffle plate 433 increases the flow distance between the outlet of the filter cartridge 421 and the pressure relief port 432, and at the same time buffers the water flow, so that the solid pollutants have sufficient time to fall, and try to avoid the solid pollutants from being carried out by the water flow from the pressure relief port 432. The direction of water flow during the whole process is shown by the arrow in the attached figure.

[0024] Furthermore, two inclined baffles 433 are provided at the top of the sedimentation area 43 to separate the sedimentation area 43 into a primary sedimentation area 434 and a secondary sedimentation area 435. The two inclined baffles 433 surround the primary sedimentation area 434 into a cone with a large top and a small bottom, and a confluence port connected to the secondary sedimentation area 435 is provided at the bottom of the primary sedimentation area 434. Solid pollutants first gather at the confluence port in the primary sedimentation area 434 and then fall into the secondary sedimentation area 435. The two baffles 433 reduce the disturbance of the water flow to the secondary sedimentation area 435, and at the same time prevent the solid pollutants with smaller density and weight from floating back to the primary sedimentation area 434, which helps to accelerate the sedimentation of solid pollutants in the secondary sedimentation area 434. The secondary sedimentation area 435 is also provided with two conical sixth baffles 436 to surround the secondary sedimentation area 435 into a cone with a large top and a small bottom. The discharge port 431 is provided at the bottom of the cone, so that the solid pollutants gather at the bottom thereof for easy discharge. The pressure relief port 432 is disposed at the top of the secondary sedimentation area 435 .

[0025] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
