Split type surface-layer waste collector suitable for circulating water shrimp culture system to allow live shrimps to return to pool by themselves

Abstract

The invention belongs to the field of aquaculture engineering, and particularly relates to a split type surface-layer waste collector suitable for a circulating water shrimp culture system to allow live shrimps to return to a pool by themselves. A backwater waste discharge groove is communicated with a water flow distribution tank through a communication pipe, a live shrimp anti-escape basket is detachably placed in the backwater waste discharge groove, a culture pool drainage pipe is connected with the backwater waste discharge groove, and the live shrimp anti-escape basket is provided with a channel for live shrimp returning to the pool; the water flow distribution tank is connected with an intermittent backwater drainage pipe and a normally open drainage pipe respectively, an intermittent backwater level difference adjustment pipe is inserted into one end of the intermittent backwater drainage pipe, a water level adjustment pipe is inserted into one end of the normally open drainage pipe, the other end of the intermittent backwater drainage pipe and the other end of the normally open drainage pipe are connected with a main backwater pipeline, and a valve is installed on the intermittent backwater drainage pipe. The waste collector is combined with an intermittent backwater aquaculture technology for shrimp farming by using circulating water, shrimp shells and dead shrimps can be collected conveniently, overflowing and shrimp escape are prevented, and installation, disassembly and washing are convenient.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a split-type surface dirt collector suitable for live shrimps in a circulating water shrimp farming system to automatically return to ponds. 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. key to success. Most of the surface sewage collection devices of the existing circulating water shrimp farming system are designed in one piece. The sewage collection basket is small and easy to block, and once the overflow occurs after the blockage, the shrimp will escape, and the improper adjustment of the bottom sewage discharge gap will easily lead to the accumulation of live shrimp, etc....

Problems solved by technology

Most of the surface sewage collection devices of the existing circulating water shrimp farming system are designed in one piece. The sewage collection basket is small and easy to block, and once the overflow occurs after the blockage, the shrimp will escape, and the improper adjustment of the bottom sewage discharge gap will easily lead to the accumulation of live shrimp, etc. problems, increasing the workload of the production management process
