Abstract

The invention belongs to the technical field of fishery culture and discloses an air-lift water-pushing aerator. The aerator is provided with a pneumatic tube; the pneumatic tube is provided with an outlet duct; a check valve is hinged to the inner of the outlet duct; the pneumatic tube is fixed on a pneumatic tube adhesion framework; a steel pipe for fixing is welded on an outer side of the pneumatic tube adhesion framework; an inclined flow deflector is welded on one side of the pneumatic tube adhesion framework. According to the air-lift water-pushing aerator in the invention, the aerator is placed about 20 cm under water surface, a blower fan is used for air supply, air overflows in the horizontal direction during passing through the device and pushes water to form a flow so that air can flow in a whole pool; the radiation scope is wide, energy consumption is low and aeration is efficient.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an air-lift type water pushing and oxygen-enhancing device. Background technique [0002] There are currently two ways to aerate aquaculture ponds: impeller stirring oxygenation and bottom pipe oxygenation. [0003] The impeller is agitated for oxygenation. The motor fixed on the floating ball drives the impeller to rotate to agitate the water body, so that the oxygen in the air is dissolved into the water body through the stirring action of the impeller to achieve the purpose of oxygenation. Generally, every 10 acres of aquaculture ponds need to be equipped with 2 sets of 3Kw impeller aerator. The impeller stirring oxygenation has the disadvantages of large unit energy consumption and small effective oxygen supply area. [0004] The bottom pipe is aerated, and the air is transported into the microporous pipe located at the bottom of the aquaculture pond through...
