Controlled circulating water shrimp culture system and working method

Abstract

The invention relates to a controlled circulating water shrimp culture system. A double-layer drain pipe passing through the bottom of a pond is arranged in the center of the culture pond, the double-layer drain pipe includes an inner drain pipe and an outer drain pipe arranged coaxially; multiple sets of side screens which are in 180-degree central symmetry and equal in size are arranged around the inner drain pipe at intervals e; bottom screens in one-to-one correspondence with the side screens in position are centrally symmetrically arranged on a lower circular chassis; a set of centrally symmetrical side openings are formed around the outer drain pipe and correspond to the side screens; bottom openings corresponding to the side openings are centrally symmetrically formed in an upper circular chassis; a visual device is fixed on the side of the double-layer drain pipe, and the visual device downwards detect in real time the amount of shrimp shells in the upper circular chassis, anda control system automatically controls a rotating mechanism to drive the outer drain pipe and the upper circular chassis to rotate synchronously according to the data feedback of the visual device, so that the side openings and bottom openings are aligned with the appropriate side screens and Bottom screens.

Description

technical field [0001] The invention relates to a controlled circulating water shrimp farming system and a working method, belonging to the technical field of circulating water shrimp farming. Background technique [0002] my country is a big country for prawn farming. Domestic prawn farming is mainly based on extensive pond farming. The traditional farming model has a low yield of prawns, and is also seriously affected by climatic conditions. The large emissions during the breeding process also cause environmental damage It is easy to cause cross-infection among ponds in shrimp farming areas. Problems such as low output and continuous diseases have seriously restricted the healthy and sustainable development of my country's shrimp farming industry. Due to its advantages of controllability, high efficiency, environmental protection, water saving and land saving, the recirculating aquaculture mode is gradually being applied and promoted in the field of aquaculture, and it is ...
