Vortex generator, vortex generating system and vortex convection oxygenation method

Abstract

The invention discloses a vortex generator, a vortex generating system and a vortex convection oxygenation method, and relates to the technical field of oxygenation devices. The vortex generator comprises a waterproof motor which is used for providing power for convection of bottom layer water and upper layer water, a mixed flow impeller which is arranged on the waterproof motor, fixedly arrangedon a power output shaft of the waterproof motor and can synchronously rotate together with the power output shaft of the waterproof motor so as to pump water, a vortex generating piece which is arranged on the side, away from the waterproof motor, of the mixed flow impeller and used for allowing water to flow in the mixed flow impeller at different speeds to form vortex, and a flow guide protection cover which is arranged on the waterproof motor and used for protecting the mixed flow impeller and guiding water flowing in the vortex generating piece out of the vortex generating piece in different directions. According to the technical scheme, vortex can be generated in water, the convection of the bottom layer water and upper layer water is driven, the water temperature difference is eliminated, the water quality is improved, and the vortex generator has the advantages of being high in oxygenation efficiency, good in oxygenation effect and capable of saving electric energy.

Description

technical field [0001] The invention relates to the technical field of oxygenation equipment, in particular to a vortex generator, a vortex generation system and a vortex convection oxygenation method. Background technique [0002] In summer, the temperature in most areas is about 35 degrees Celsius, the water temperature at the bottom of fish ponds is generally about 20-25 degrees Celsius, and the temperature difference between the water surface and the bottom reaches more than 10 degrees Celsius. Because the density of water decreases with the increase of water temperature, the density of the upper water is lower than that of the bottom water, which makes it difficult for the water in the fish pond to convect, and the bottom water cannot flow to the water surface for a long time, resulting in hypoxia at the bottom. Worse in the morning and evening. Therefore, fish ponds are more likely to have floating heads and flooded ponds in the morning and evening of summer, and need...

AI Technical Summary

Problems solved by technology

[0003] Existing fish pond aerators generally spray water on the water surface or stir the water surface with an impeller to increase oxygen, which cannot achieve comprehensive convection of the water in the fish pond, eliminate water temperature differences, and cannot fundamentally solve the problem of oxygen deficiency in the bottom water of the fish pond , cure the symptoms but not the root cause, oxygenation is limited, needs to be improved
