Aeration device for schizothorax fish culture

Abstract

An aeration device for schizothorax fish culture comprises an annular plate. The bottom side of a box is fixedly connected to the middle of the top side of the annular plate, and a vertical tube is fixedly mounted in the annular plate. The upper end of a tapered tube is fixedly connected with a lower port of a three-way tube. An upper port of the three-way tube is fixedly connected with a water inlet of a first electromagnetic valve, and an annular floating plate is fixedly mounted on the bottom side of the annular plate (the buoyancy of the annular floating plate is large enough to carry theannular plate and devices above the annular plate, and the diameter of the annular floating plate is large enough to avoid the annular plate from tilting to one side). The aeration device has the advantages that the aeration device has a simple structure and ingenious design and integrates water spray aeration with inflation aeration, aeration at different depths of a fish pond can be realized, aeration flows can be diffused in a wide range, disturbance of inflation aeration on fish manure at the bottom of the fish pond can be reduced, the fish manure at the bottom of the fish pond can be collected by water spray aeration, a large amount of the fish manure accumulated under an aerator can be cleaned to improve the fish pond, market demands can be met, and the aeration device is suitable for promotion.

Description

technical field [0001] The invention belongs to the field of aeration devices for fish farming, in particular to an aeration device for schizothoracic fish farming. Background technique [0002] Aerator is a machine often used in fish farming; its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic, and it can also inhibit the growth of anaerobic bacteria in the water and prevent pool water Deterioration threatens the living environment of fish; however, the existing aerators have a single function. Water jet aeration is suitable for shallow water aeration, and air-filled aeration is suitable for deep water aeration. A single oxygenation method cannot satisfy oxygenation at different depths. In addition, inflation and oxygenation can easily disturb the fish feces at the bottom of the pond, causing the water at the bottom of the fish pond to be turbid, which is not conducive to the breathing of fish. High, a l...
