The technical scheme includes that the bottom sewage discharge device for the circulating water fixed bed biological filter is provided with a bottom plate, the bottom plate is of a conical structure with a wide upper part and a narrow lower part, a sewage discharge hole is formed in the bottom of the conical structure, a sewage discharge vertical pipe is arranged below the sewage discharge hole, a sewage discharge horizontal pipe is connected below the sewage discharge vertical pipe, a sewage discharge main pipe is connected above the sewage discharge horizontal pipe, the bottom plate is uniformly distributed and fixed on the bottom surface of the filter, and the upper surface of the bottom plate is lower than the bottom surface of the filter.

Preferably, the bottom plate is made of PVC.

Preferably, the upper surface of the bottom plate is square.

Preferably, the bottom plate is distributed on the bottom surface of the whole filter tank.

Preferably, the bottom plate is fixed on the bottom surface of the filter tank by cement.

Preferably, the pipe diameter of the main sewage drainage pipe is larger than that of the transverse sewage drainage pipe, and the pipe diameter of the transverse sewage drainage pipe is not smaller than that of the vertical sewage drainage pipe.

The beneficial effects of the utility model are that,

(1) the bottom plate is embedded on the bottom surface of the filter tank, the bottom plate is of a conical structure with a wide top and a narrow bottom, the conical bottom is provided with a sewage discharge hole, and impurities precipitated in the filter tank enter the sewage discharge hole under the action of gravity, so that the impurities are prevented from being deposited at the bottom of the filter tank and affecting the water quality, and the impurities are discharged through a sewage discharge pipe to be collected and treated in a centralized manner;

(2) the device simple structure can realize the automatic clearance in filtering pond, has reduced artifical intensity of labour to the clearance is timely, has effectively promoted the quality of water in the filtering pond.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1-4, a circulating water fixed bed biological filter bottom waste fitting discharging is equipped with filter 1, is equipped with bottom plate 2 in the filter 1, and bottom plate 2 adopts PVC material or other rigid plastic material, and bottom plate 2 is the toper structure of narrow width down, and toper structure bottom is equipped with blowoff hole 3, and blowoff hole 3 has blowdown standpipe 5, and the blowdown standpipe 5 below is connected the blowdown and is violently managed 8, and the blowdown is violently managed and is connected the blowdown and be responsible for 6 on 8, and impurity is responsible for 6 discharges through the blowdown and carries out centralized processing. The main sewage discharge pipe 6 can be provided with a valve for switching the filter sewage discharge, and the valve can be a manual valve or an electric valve. The outlet of the main sewage discharge pipe 6 is slightly inclined downwards, which is beneficial to discharging impurities in the main sewage discharge pipe 6. The pipe diameter of the main sewage drainage pipe 6 is larger than that of the transverse sewage drainage pipe 8, and the pipe diameter of the transverse sewage drainage pipe 8 is not smaller than that of the vertical sewage drainage pipe 5. The vertical sewage pipe 5 far away from one side of the main sewage pipe 6 is called an end vertical pipe 10, the end vertical pipe 10 is connected with the horizontal sewage pipe 8 through an elbow B9, and the main sewage pipe 6 is connected with the horizontal end pipe 11 on the outermost side through an elbow A7. The end parts are connected by the elbows, so that the deposition of impurities on the pipe ends can be avoided.

A plurality of bottom plates 2 are uniformly distributed and fixed on the bottom surface 4 of the filter tank through cement, the bottom plates 2 are fully distributed on the whole bottom surface 4 of the filter tank, and the upper surfaces of the bottom plates 2 are slightly lower than the bottom surface of the filter tank 1, so that the collection of impurities at the bottom of the filter tank is facilitated. The upper surface of the bottom plate 2 can adopt a square or rectangular structure, so that the space between the bottom plates 2 is smaller, and the deposition of impurities on the bottom surface of the filter tank 1 is reduced.

This application is through inlaying bottom plate 2 on 1 bottom surface in filtering pond, narrow toper structure under the wide in bottom plate 2 adoption, and the toper bottom sets up the blowoff hole, the impurity that deposits in filtering pond 1 gets into blowoff hole 3 under the action of gravity, the deposit of impurity in filtering pond 1 bottom has been avoided, the device simple structure, can realize the automatic clearance in filtering pond 1, no longer need artifical regular cleaning filtering pond 1, the artifical intensity of labour has been reduced, and the clearance is timely, effectively promote the quality of water in filtering pond 1, the aquaculture environment has been improved.

However, the above description is only exemplary of the present invention, and the scope of the present invention should not be limited thereby, and the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should be covered by the claims of the present invention.
