Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the water circulation system for fish culture provided by the utility model comprises a fish pond 1, a sedimentation tank 2 and a sieve bend, wherein,

an isolation net 3 is fixed at the bottom of the fish pond, and a fish pond water drainage pipe 4 is connected to the bottom of the fish pond below the isolation net;

the sedimentation tank is provided with a conical bottom, a return pipe 5 is fixed in the middle of the sedimentation tank, a water outlet of the return pipe is connected with a reflecting plate 7 through a plurality of connecting columns 6, a sedimentation tank water inlet pipe of the sedimentation tank extends into the upper side of the inside of the return pipe, and a sedimentation tank water inlet pipe 8 is communicated with a fish pond water outlet pipe;

the sieve bend includes sieve bend 9, is located the pond 10 is received to sieve bend downside, and is located the blowdown pond 11 in the sieve bend outside, the pond of receiving in pond outlet pipe 12 with the fish pond inlet tube 13 intercommunication in fish pond.

In the embodiment of the application, the separation net is arranged at the bottom of the fish pond, the caliber of the separation net can block fish, but dirt such as excrement and the like is not influenced to be settled to the lower side of the separation net. After the dirt in the fish pond is deposited and discharged to the bottom of the fish pond, the dirt can be discharged through a drain pipe of the fish pond.

Alternatively, a plurality of fish ponds may be provided, and the fish ponds are connected by a connecting pipe (not shown) which is located at the lower side of the separation net. The connecting pipe and the fish pond water discharging pipe can be equal in width, so that a water channel is formed at the bottom of the fish pond, the water channel is regularly discharged, and dirt at the bottom of the fish pond is discharged.

The sewage in the fish pond passes through the fish pond drain pipe and advances water piping connection with the sedimentation tank, and the sedimentation tank inlet tube stretches into to the back flow inboard for sewage flows by the back flow inboard, and flows down along the back flow, blocks for the reflecting plate when flowing to the reflecting plate position, makes sewage flow from the space between reflecting plate and the spliced pole. Because the arrangement of the return pipe and the reflecting plate, sewage can not directly impact the bottom of the sedimentation tank, water flow disturbance in the sedimentation tank is reduced, and sedimentation of sewage is facilitated.

After the sewage is settled in the sedimentation tank, the sewage is settled to the bottom of the sedimentation tank, and a drainage pipe of the sedimentation tank positioned at the upper part of the sedimentation tank can discharge the water at the upper part of the sedimentation tank.

Discharged water is poured into the sieve bend in the sedimentation tank, and the sieve bend has less bore, can intercept the less particulate matter of aquatic, and then the clear water can flow into and receive the pond and pour back to the fish pond in through the fish pond inlet tube, realizes the cyclic utilization of water. The dirt of the smaller granule that the arc screen cloth intercepted can be impacted to in the blowdown pond under the effect of rivers, can finally discharge through the drain pipe in blowdown pond.

In actual use, the water discharged by the water discharge pipe of the water receiving pond can be discharged into the biological filter pond, the waste in the water is decomposed through the biological filter pond, and then the waste is guided into the fish pond to realize water circulation.

In an optional implementation that this application embodiment provided, fish pond upper portion is fixed with the face and inhales the mechanism, the face is inhaled the mechanism and is included face suction inlet 14, encircles face suction inlet fixed grid plate 15 and with the face drainage pipe 16 is inhaled to the face of face suction inlet intercommunication, the face drainage pipe with fish pond drain pipe intercommunication.

Oil films, foams and other wastes often remain on the water surface in the fish pond, can be sucked out through the surface suction port and are led into a fish pond water drainage pipe through the surface suction and drainage pipe, and are filtered together with sewage at the bottom of the fish pond.

The face suction opening can be level with the surface of water in the fish pond, can leave the space between the grid tray, and rivers flow in the face suction opening through the space between the grid tray for great foam can be smashed, also can avoid great filth to block face suction opening.

Optionally, a sludge discharge pipe 17 is fixed in the sedimentation tank, an inlet of the sludge discharge pipe is located at the tail end of the conical bottom of the sedimentation tank, and an outlet of the sludge discharge pipe is located outside the sedimentation tank.

In an optional implementation manner provided by the embodiment of the application, the sedimentation tank drain pipe 18 of the sedimentation tank is located above the arc-shaped screen, and a spray head 19 is connected to a pipe orifice of the sedimentation tank drain pipe.

The spray head can be arranged above the arc-shaped screen mesh, so that water is uniformly sprayed out through the spray head, and the filtering of tiny particles in water is facilitated.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
