AI Technical Summary

Technical Problem

In traditional aquaculture equipment, the short contact time between air and water results in poor oxygenation. The air quickly floats to the surface after being sprayed out, failing to effectively dissolve oxygen and affecting water quality and aquaculture results.

Method used

A feeding and aeration device for Litopenaeus vannamei ponds is designed, comprising a carrier, a feeding mechanism, and a mixing mechanism. Through the synergistic action of an air supply unit, a flow divider, a mixing unit, a turbine fan, and a water-stirring unit, the airflow and water flow are fully mixed. The reverse stirring of the turbine fan and the water-stirring unit enhances fluid turbulence. Combined with a bubble flotation component and ceramic particles, the dissolution time of bubbles in water is extended, thereby improving oxygen dissolution efficiency.

Benefits of technology

It achieves full dissolution of oxygen in the water, increases dissolved oxygen content, enhances water circulation and flow, provides a sufficient oxygen environment, reduces bubble escape, and improves aquaculture efficiency and water quality stability.

Abstract

The application relates to a feeding and oxygenation device and method for a white shrimp (Penaeus vannamei) breeding pond, wherein the device comprises a carrier, a feeding mechanism and a mixing mechanism, and the feeding mechanism and the mixing mechanism are arranged on the carrier; the mixing mechanism comprises a gas supply part, a flow distribution seat and a mixing unit, the flow distribution seat is connected with the gas supply part and the mixing unit respectively, the gas supply part supplies gas to the mixing unit through the flow distribution seat; a first gas outlet is arranged on the flow distribution seat; the mixing unit comprises a water inlet disc, a mixing part, an impeller, a water disturbance unit and a water inlet shaft, the water inlet disc is fixed on the top of the mixing part, and a mixing cavity is arranged in the mixing part; the water inlet shaft can drive the impeller and the water disturbance unit to rotate around the axis of the water inlet shaft under the drive of the gas supply part; the device solves the problem that the air supplied into the breeding pond is in contact with water for a short time, the supplied air is immediately floated out of the water surface after being sprayed, and the oxygenation effect of the pond is poor.
