A fully automatic timing sewage discharge device for a closed circulating water system breeding pond

Abstract

The invention relates to a method and device for fully automatic timing sewage discharge of a breeding pond in a closed circulating water system. The method includes the following steps: constructing a sewage discharge pond outside the cultivation pond, then recessing the bottom of the cultivation pond to form a sewage collection pond, laying a sewage pipe, Connect the sewage collection tank with the sewage discharge tank, and use the siphon principle of the sewage discharge pipe to discharge sewage. The device for realizing the above method includes, the circulating water supply pipe and drain pipe in the culture pond, the sewage collection tank, the sewage discharge pond, the bottom of the sewage collection pond is provided with a sewage discharge pipe, and the other end of the sewage discharge pipe extends to the outside of the cultivation pond and forms an inverted U-shaped pipe It is connected with the sewage tank, and the highest point of the inverted U-shaped pipe is also connected with a vacuum breaking pipe and a vacuum pipe, the vacuum breaking pipe extends into the culture pond, and the vacuum pipe is connected with a vacuum pump controlled by a computer program. The invention utilizes the siphon phenomenon to realize the automatic sewage discharge of the culture pond, has the protection function of anti-drainage, and effectively solves the problems of time-consuming and laborious sewage discharge of the culture pond, accidental emptying and the like.

Description

technical field [0001] The invention relates to an industrialized closed circulation aquaculture facility, in particular to a fully automatic timing sewage discharge device for a culture pond of a closed circulation water system. Background technique [0002] The closed circulation aquaculture system is the representative of the current international advanced aquaculture mode, and it is also the main direction of the future development of the aquaculture industry, which has attracted the attention of the world. my country's land-based industrial fish farming started relatively late, with relatively low levels of technical equipment and automation control. After years of development, my country's closed industrial recirculating aquaculture has reached a certain scale. As of 2013, the area of ​​industrial recirculating aquaculture Nearly 400,000 m2, with a rapid development momentum. However, according to the follow-up investigation on the development and operation of domestic...
