Marine controllable open-type aquaculture water tank circulating water system device

Abstract

The invention relates to the technical field of marine equipment, in particular to a marine controllable open-type aquaculture water tank circulating water system device. The device comprises an aquaculture tank and a seawater tank, wherein the aquaculture tank is divided into four aquaculture areas which can communicate with one another, a water outlet leading to seawater outside a ship is formed in the bottom of each aquaculture area, the seawater tank is installed on the side of an aquaculture work ship, and communicates with each aquaculture area, seawater in the seawater tank is pressurized and conveyed into each aquaculture area through a seawater pump, annular water flow from top to bottom is formed in each aquaculture area, and the annular water flow tends to flow to the water outlets. The device is simple in principle, can be suitable for aquaculture water tanks of various sizes, can form a stable flow field in the tanks, is good in energy-saving effect, and well provides the most suitable aquaculture environment for live fishes.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a circulating water system device of a controllable open type aquaculture tank at sea. Background technique [0002] As an emerging breeding technology, the breeding boat has the biggest advantage of being able to perform farm-to-site farming according to the different breeding environments required in the breeding process. However, during the breeding process, the residual bait and feces produced by the cultured fish will be distributed in the water body below the breeding cabin. With the increase of organic matter, the organic matter will consume a large amount of dissolved oxygen during the oxidation process, and the ammonia nitrogen and nitrite in the water body are poisonous and harmful. The substance content will continue to increase, and the transparency of water quality will decrease, resulting in the deterioration of the breeding environment, affecting the healt...

Problems solved by technology

However, during the breeding process, the residual bait and feces produced by the cultured fish will be distributed in the water body below the breeding cabin. With the increase of organic matter, the organic matter will consume a large amount of dissolved oxygen during the oxidation process, and the ammonia nitrogen and nitrite in the water body are poisonous and harmful. The content of substances will continue to increase, and the transparency of water quality will decrease, causing the deterioration of the breeding environment, affecting the healthy growth of aquaculture products, and increasing the risk of breeding

At the same time, if the seawater containing a large amount of pollutants is directly discharged into the sea, it will cause environmental pollution
