A fishery aerator based on a volute centrifugal fan and its application method

Abstract

The invention discloses a fishery aeration machine based on a volute centrifugal fan, which comprises a hard collecting tube, a bubble collecting umbrella submerged in breeding water and a hard gas injection pipe; Through the cylindrical structure, the tube of the hard collecting tube is a bubble concentration channel that runs through up and down; the bubble collecting umbrella is a cover structure with a flared lower end, and the bubble collecting umbrella is The lower end of the hard collecting tube, and the upper end of the bubble collecting umbrella is connected to the hard collecting tube, and the hard gas injection pipes in a number of vertical postures are distributed outside the hard collecting tube, and several The hard gas injection pipes in a vertical posture are distributed in a circular array along the hard collector tube; and the lower end of each of the hard gas injection pipes passes through the umbrella surface of the bubble collection umbrella; the structure of the present invention is simple, adopting The bubble collecting umbrella structure utilizes the flow energy generated by the rise of the bubbles, making the continuous rotation of the slurry transfer so that the water at the air leak hole on the air vent head is always in a flowing state.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a fishery aerator based on a volute centrifugal fan and a method for using the same. Background technique [0002] In the field of fish farming, if the breeding density is high, the pond water will be hypoxic, which will cause a large number of fish to die. Therefore, an aerator is needed. The existing aerator has high power consumption and high noise. Water splashes cause disadvantages such as affecting roadside pedestrians. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fishery aeration machine based on a volute centrifugal fan with low noise and strong oxygenation effect and its use method. [0004] Technical solution: In order to achieve the above object, a fishery aeration machine based on a volute centrifugal fan of the present invention includes a hard collectin...
