Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, the main part of the sewage discharge device of the present invention is located inside the culture tank 11, and the main sewage pipe 10, the standpipe 9 and the electronic control part are located outside the culture tank 11, including a surface overflow sewage device for removing foam floating objects on the surface of the culture water body 1. The bottom surge sewage discharge device for removing the bottom sewage of the aquaculture water body and the variable flow adjustment device for high-speed sewage discharge. The surface overflow sewage discharge device includes a sewage collection tank 1, a water level adjustment pipe 3 and an upper sewage pipe 4. The bottom surge sewage discharge device It includes the bottom sewage suction pipe 5, the surge pipe 6, the sewage collection tank 1, the water level adjustment pipe 3 and the upper sewage pipe 4. The variable flow adjustment device includes the lower sewage pipe 7 connected ...

Embodiment 2

[0030] Such as image 3 As shown, the difference between the present embodiment and the first embodiment is: when the automatic sewage discharge control function is reduced in the first embodiment, the lower sewage pipe 7, the electric valve 8, the circuit 13 and the controller 14 can be removed. Except that the present embodiment does not have the automatic sewage discharge control function in the first embodiment, the implementation of the functions of other components is the same as that of the first embodiment.

Embodiment 3

[0032] Such as Figure 4 As shown, the present embodiment is suitable for the breeding ponds with bottom sewage pipes, and the difference with embodiment one is that the bottom sewage pipes 15 are pre-buried pipelines, which are pre-buried below the ground plane 16 where the cultivation tank 11 is placed; The bottom is a slope inclined downward from the outside to the inside, and the bottom sewage suction pipe 5 is located above the lowest point of the bottom of the breeding tank 11; The opening is connected, and the other end is connected with the main sewage pipe 10. A normally closed cover 17 is provided at the opening, and the cover 17 is only opened when the cultivation tank 11 needs to be drained. The realization of other functions is the same as that of the first embodiment. same.

Abstract

The invention belongs to the field of aquaculture engineering, particularly relates to an efficient full-time double-layer-flowing pollution discharging device. The efficient full-time double-layer-flowing pollution discharging device comprises a surface overflowing pollution discharging unit, a bottom surging pollution discharging unit and a flow varying and adjusting unit, wherein the surface overflowing pollution discharging unit is used for removing foam floating objects on the surface of an aquaculture water body, the bottom surging pollution discharging unit is used for removing sewage at the bottom of the aquaculture water body, and the flow varying and adjusting unit is used for high-speed pollution discharging. When water inflowing and water outflowing of an aquaculture system are normal, biological excrement in the water body can be discharged through a surface flow and a bottom flow at the same time, and especially, short-time efficient pollution discharging can be realized by changing a drainage water level difference by automatically controlling and opening an electric valve timely or manually plugging in or unplugging a water level adjusting unit. The efficient full-time double-layer-flowing pollution discharging device is applicable to pollution discharging of culturing ponds, made of different materials, in an industrialized recirculating aquaculture system, especially suitable for culturing tanks which are free of pre-buried bottom pollution discharging structures and made of flexible materials, and capable of overcoming the difficulty in pollution discharging at the bottom of the water body.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a double-layer flow full-time high-efficiency sewage discharge device. Background technique [0002] In the industrialized recirculating aquaculture system, the sewage design of the aquaculture tank is a key technology in the design of the aquaculture system. Circular and near-circular aquaculture tank sewage pipes are usually set in the center of the aquaculture tank, and the solid particles such as feces and bait produced by the aquaculture organisms are discharged by means of bottom sewage discharge. [0003] The Chinese invention patent published on February 10, 2010 with the publication number CN101642073A discloses a solid-liquid separation device for circulating water aquaculture ponds. The solid-liquid separation device takes into account the function of removing surface and bottom dirt; however The disadvantage is that when the bottom of the solid-liquid separatio...
