Submerged aeration water culturing machine

Abstract

The invention discloses a submerged aeration water culturing machine which can be applied to the fields of cultivation and environmental protection and is used for improving water quality, comprising a float, a locating rod and a water culturing mechanism. The invention is characterized in that the water culturing machine is provided with an aeration mechanism; the aeration mechanism comprises an air pump and an air distributing device; the water culturing mechanism comprises a driving motor and a reduction gear and blades which are connected with the driving motor; the aeration mechanism and the water culturing mechanism can be operated separately or simultaneously, and the optimal working mode can be selected according to actual requirements. The culturing mechanism in the invention can guide a large amount of water from the water bottom to the water surface to form circulating water flow; the aeration mechanism can deliver a large number of micro bubbles to the water body, thus improving oxygen content of water, taking away harmful gas in water, and accelerating ecological purification of water; and the water culturing mechanism is characterized by energy saving and low noise.

Description

technical field [0001] The invention relates to a rotary impeller machine with the function of aeration and oxygenation for water farming operations, and specifically refers to an aeration machine that can be applied to the fields of aquaculture and environmental protection to improve water quality. Background technique [0002] The impeller type aerator and the water wheel aerator all use electric power to forcibly raise the water to supply oxygen. If the water flow rate is increased, the power consumption will increase in proportion to the third power of the flow rate. The electric energy can only increase oxygen to a part of the water body that raises the water surface, and the water at the bottom of the pool remains stagnant, and the oxygen increase effect is poor, resulting in hypoxia at the bottom. Bottom rot and smelly issues. [0003] Inflatable aerators, microporous aeration aerators, etc. use electric power to pump air to the bottom of the water, and the air bubbl...

AI Technical Summary

Problems solved by technology

Aerated aeration and microporous aeration can increase oxygen at the bottom of the water and significantly increase the dissolved oxygen at the bottom. However, the water body with aerated aeration and microporous aeration is in a static state and cannot achieve high dissolved oxygen. Rapid exchange and convection of water body, especially in high temperature state in summer, the surface temperature of the fish pond is high, and the temperature of the bottom part is low. Usually, the density of water decreases with the increase of temperature. The density of the lower part of the fish pond is high, and the density of the upper part is low. The convection of the water body will cause the lower water body to have poor activity due to the lack of convection and sunlight, and harmful bacteria will multiply quickly, which is not conducive to the survival of fish and shrimp.
