An intelligent rapid-oxygen charging and purifying oxygen increasing system for aquaculture

Abstract

The invention relates to an intelligent rapid-oxygen charging and purifying oxygen increasing system for aquaculture. The system mainly consists of a conveying device, a filter device, a stirring device, an oxygen increasing device and a controller. The conveying device consists of a water outlet pipe, a water inlet pipe and a control valve. The stirring device consists of a stirring motor, a stirring bucket and an impeller. The filter device consists of a first layer sand filter net, a second layer sand filter net and a water purifier. The oxygen increasing device consists of an air compressor, an aeration channel and an aeration disc. An oxygen sensor at the water outlet pipe can monitor the oxygen content of a water body flowing out of the water outlet pipe in real time ceaselessly; a controller connected with the oxygen sensor controls the elements to work cooperatively, so that the out-flowing water body can maintain a stable state; the sand filter nets on the water inlet pipe can protect the stirring motor and the impeller of the apparatus and prolong the service life of the water purifier.

Description

technical field [0001] The invention relates to a water purification and oxygenation device, in particular to an automatic oxygenation delivery device used in fish pond aquaculture. Background technique [0002] At present, there are many reasons for water pollution in fish ponds. Specifically, in surface freshwater systems, phosphate is usually the limiting factor for plant growth, while in seawater systems, ammonia nitrogen and nitrate often limit plant growth and total production. . The substances that cause eutrophication are often the nutrients that are limited in these water systems, for example, phosphorus is usually limited in normal freshwater systems, so increasing phosphate will lead to excessive growth of plants, while in seawater systems Phosphorus is not lacking, but nitrogen content is limited, so the addition of nitrogen-containing pollutants will eliminate this limiting factor, resulting in excessive growth of plants. Domestic sewage, fertilizer, food and ...

Problems solved by technology

[0003] In the fish farming industry, most of the current aeration methods use aerators. Aerators are generally divided into impeller type, waterwheel type and jet type. The impeller type and waterwheel type aerators are used during use. , if the speed is maintained at a low speed, it is easy to spray the fish, causing the fish to be injured and causing the farmers to suffer losses
