A kind of oxygenation equipment for fish farming

Abstract

Disclosed are fish farming aerating equipment and a use method therefor, comprising an aerator (1). The aerator (1) comprises a first accommodating cavity (2), a second accommodating cavity (3), and a third accommodating cavity (4) in a downward sequence. The lower part of the first accommodating cavity (2) is in communication with the third accommodating cavity (4) via a first pipe (5). The bottom part of the first accommodating cavity (2) and the upper part of the second accommodating cavity (3) are not in communication with each other. The lower part of the second accommodating cavity (3) is in communication with a second pipe (6). The bottom part of the second accommodating cavity (3) and the upper part of the third accommodating cavity (4) are in communication with each other via a third pipe (7). One end of the third pipe (7) extends into the upper part of the second accommodating cavity (3) to form a first inwardly extended part (701); the other end of the third pipe (7) extends into the upper part of the third accommodating cavity (4) to form a second inwardly extended part (702). The present method, by providing the aerator, utilizes the principle of water and air squeezing each other in a sealed space to achieve a continuous water spraying effect, thus greatly reducing the energy consumption of the aerating equipment, and at the same time, by configuring the aerator as a row structure, allows the density of dissolved oxygen to be evenly distributed throughout an entire area of water, thus effectively increasing the volume of dissolved oxygen in the water.

Description

technical field [0001] The invention relates to the field of fish pond oxygenation equipment, in particular to a fish farming oxygenation equipment and a method for using the same. Background technique [0002] In the field of fish pond cultivation, aeration devices are often used to increase oxygen in fish ponds, such as common water jet aerators, the working principle of which is roughly that the water jet aerator is installed in the center of the fish pond, Use the water pump to send water into the sprinkler and then spray it into the air, thereby increasing the contact area between air and water, so that excessive carbon dioxide in the water body and high dissolved oxygen in the air enter the water body, and at the same time make the upper dissolved oxygen reach saturation. The final water body enters the lower water body by flipping, so that the water body in the fish pond can dissolve as much oxygen as possible, so as to avoid the decline of the fish's physique due to ...
