Abstract

The utility model discloses a pollution discharge device for a high-density prawn culture pond, which comprises the prawn culture pond, a blow-off pipe and a pollution discharge pool, wherein the pollution discharge pool is positioned on one side of the prawn culture pond. The pollution discharge device is characterized in that a sewage outlet is formed at the central part of the bottom surface of the prawn culture pond; one end of the blow-off pipe is connected with the sewage outlet formed on the prawn culture pond, and the other end of the blow-off pipe is connected with the lateral bottom of the pollution discharge pool; and the bottom surface of the prawn culture pond with a lower central part and higher edges is a surface with a certain gradient. The gradient of the bottom surface of the prawn culture pond ranges from 2 percent to 3 percent. The sewage outlet is formed at the central part of the bottom surface of the prawn culture pond, the bottom surface of the prawn culture pond is designed into a surface with a lower central part and higher edges, and an oxygen increase machine thrashes water clockwise to generate whirling water flow to gather precipitates to the center of the prawn culture pond, so that the pollution discharge capability of the prawn culture pond is improved greatly, the pollution discharge is more complete, high quality environment is provided for the growth and the propagation of prawns, and the productive output of the prawn cultivation is improved.

Description

A kind of high density shrimp culture pond blowdown apparatus

Technical field

The utility model relates to a kind of high density shrimp culture pond, specifically is a kind of high density shrimp culture pond blowdown apparatus.

Background technology

Traditional high density shrimp culture pond carries out blowdown from its side, is difficult to during blowdown the sediment waste emptying is caused and cultures later stage water quality deterioration in the pond, has influenced the growth of prawn, and the output of prawn culturing can sharply be descended.

The utility model content

Thereby the utility model purpose is to provide the high density shrimp culture pond blowdown apparatus of the more thorough raising of a kind of blowdown prawn culturing output.

To achieve these goals, the technical solution adopted in the utility model is: a kind of high density shrimp culture pond blowdown apparatus, include shrimp culture pond, blow-off pipe, pollution discharge pond, pollution discharge pond is positioned at a side of shrimp culture pond, it is characterized in that: the portion of bottom center of described shrimp culture pond is provided with sewage draining exit, one end of blow-off pipe is connected with the sewage draining exit of shrimp culture pond, and the other end is connected with the side bottom of pollution discharge pond; The bottom surface of described shrimp culture pond is that a central part is low, the face that certain slope is arranged that the edge is high.

The gradient of the bottom surface of described shrimp culture pond is 2%-3%.

Be provided with tubulose blowdown control plug in the described pollution discharge pond, the end of described tubulose blowdown control plug is filled in the pipe box of the sewage draining exit bottom the pollution discharge pond, during blowdown the blowdown control valve is extracted, sewage is discharged by sewage draining exit, during water filling the blowdown control valve is filled in pipe box and gets final product.

The beneficial effects of the utility model: owing to sewage draining exit is located at the portion of bottom center of shrimp culture pond, and the bottom surface of shrimp culture pond is designed to a face that central part is low, the edge is high, improved the pollution discharge capability of shrimp culture pond greatly, make blowdown more thorough, thereby for the growth of prawn provides the environment of high-quality, so improved the output of prawn culturing.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1, shrimp culture pond; 2, bottom surface; 3, sewage draining exit; 4, blow-off pipe; 5, pollution discharge pond; 6, aerator; 7, tubulose blowdown control plug; 8, pipe box.

Embodiment

As shown in Figure 1, a kind of high density shrimp culture pond blowdown apparatus, include shrimp culture pond 1, blow-off pipe 4, pollution discharge pond 5, pollution discharge pond 5 is positioned at a side of shrimp culture pond 1, it is characterized in that: bottom surface 2 central parts of described shrimp culture pond 1 are provided with sewage draining exit 3, one end of blow-off pipe 4 is connected with the sewage draining exit 3 of shrimp culture pond 1, and the other end is connected with the side bottom of pollution discharge pond 5; The bottom surface 2 of described shrimp culture pond is that a central part is low, the face that the edge is high.The gradient of the bottom surface 2 of shrimp culture pond is 2%-3%.Placing aerator 6 respectively at four jiaos of places of shrimp culture pond 1 fetches water clockwise.Be provided with tubulose blowdown control plug 7 in the pollution discharge pond 5, the end of described tubulose blowdown control plug 7 is filled in the pipe box 8 of the sewage draining exit bottom the pollution discharge pond.

Operation principle of the present utility model: during blowdown, be positioned at the aerator 6 at four jiaos of places of shrimp culture pond 1, fetch water clockwise, refuses such as residual bait ight soil are threaded to central sewage draining exit place with current, and dirt enters pollution discharge pond 5 by sewage draining exit by blow-off pipe 4.
