Device and method for removing sewage and preventing live shrimps from escaping in circulating water shrimp culture system

Abstract

The invention relates to a device and a method for removing sewage and preventing live shrimps from escaping in a circulating water shrimp culture system. The bottom sewage collecting pipe is arrangedat the bottom of the aquaculture pond with a sewage collecting outlet on it. a live shrimp escape prevention frame is arranged in a backwater sewage discharge groove, and an escape prevention net isarranged in the live shrimp escape prevention frame; one end of the bottom sewage collecting pipe is closed, and the other end of the bottom sewage collecting pipe is communicated with the inside of the escape prevention net through a backwater pipe; one end of the water level adjusting pipe is inserted into the backwater sewage discharge groove and is positioned outside the live shrimp escape prevention frame, and the other end of the water level adjusting pipe is connected with a backwater pipeline of the circulating water system through a lower backwater pipe; and the water level is adjusted by inserting the water level adjusting pipe into the height of the backwater sewage discharging groove. The device and the method for removing sewage and preventing live shrimps from escaping in circulating water shrimp culture system are not only beneficial to observing the removal of dirt and the escape condition of live shrimps, but also can regularly clean or replace the escape prevention net so as to prevent the escape prevention net from being blocked to influence the circulation of a circulating water system and effectively solve the problem of removing sewage in the process of culturing shrimps by circulating water, and can effectively prevent the live shrimps from escaping and facilitate the separation of the dead shrimps and the live shrimps.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a device and method for removing dirt and preventing live shrimp from escaping in a circulating water shrimp farming system. Background technique [0002] In the industrialized circulating water aquaculture system of prawns, how to get rid of the shrimp shells, dead shrimps and residual bait feces in the aquaculture water and prevent live shrimps from escaping is a key technology, and it is also a key technology that determines the recirculating water culture of prawns. A key link to success. [0003] The Chinese utility model patent disclosed on July 30, 2013 with the publication number CN203735271U discloses a high-level shrimp pond float type sewage device; Not applicable. The Chinese utility model patent published on October 7, 2015 with the publication number CN204682166U discloses an anti-escape device for the central sewage outlet of the shrimp pond; Escape, but t...

Problems solved by technology

However, the disadvantage is that the sewage casing and the chassis of the device are all at the bottom of the breeding water body, and the removal of dead shrimp, residual bait and feces is not easy to observe, and the removal of live shrimp cannot be detected, resulting in the loss of shrimp seedlings and increasing the microscopic amount of the follow-up sewage discharge device. Load of filter, etc.
