Problems solved by technology

However, due to the direct connection between the motor and the impeller, the speed is high, and there is a casing outside the impeller, which restricts the direction of the aeration water flow, the aeration area is small and the aeration cannot be uniform.

Embodiment Construction

[0021] Referring to the accompanying drawings, the submersible aerator includes a submersible motor 2 installed on the bottom plate 1. The submersible motor 2 can be a constant-speed motor, or a two-speed motor or a variable frequency speed-regulating motor. The upper end of the output shaft of the submersible motor is fixedly installed There is a water retaining flange, the submersible motor is connected with a reducer 3, the output shaft of the reducer 3 is fixedly connected with the water retaining flange 4, and the water retaining flange 4 is fixed with an air distributor 6, the upper end of which is There is a vertical air intake pipe 8 connected, and the upper end of the air intake pipe is fixedly equipped with push-flow blades, and the connection between the water retaining flange and the air intake pipe is provided with blades, and a plurality of blades are evenly arranged on the water retaining flange. It is 2-20, and the length of each blade can be consistent or incon...

Abstract

The invention discloses a submersible aerator which comprises a submersible motor, wherein the upper end of an output shaft of the submersible motor is fixedly provided with a water-retaining flange, the water-retaining flange is fixedly provided with an air separator, the upper end of the air separator is communicated with a vertical air inlet pipe, vanes are arranged at the joint between the water-retaining flange and the air inlet pipe, the water outlet end of each vane is provided with an air outlet, and an air pipe is connected between the air outlet and the air separator. The vanes produce radial water flow under the push and centrifugal force action, and negative pressure is produced after the water flow is spirally driven out from the back vanes, so that air is drawn out through the air outlet and flows together with the water flow; the water flow produced by the back vanes stirs and smashes the air to produce a large number of small bubbles; and since a vane wheel is rotary, the bubbles can flow through the whole bottom of a pool, thereby ensuring more uniform aeration.

Description

[0001] technical field [0002] The invention relates to a submersible aerator, belonging to the technical field of sewage treatment, suitable for the treatment of organic sewage, generally used in sewage treatment pools, and also suitable for oxygenation and water purification of rivers, lakes, bays, aquaculture, etc. . [0003] Background technique [0004] Existing submersible aerators are generally jet aeration or centrifugal aeration. The submersible motor drives the impeller to rotate, pushing the water flow into the air, and after the mixed flow is directed to a certain direction or area under the action of a fixed shell to aerate. However, since the motor is directly connected to the impeller, the rotation speed is high, and there is a casing outside the impeller, which restricts the direction of the aeration water flow, and the aeration area is small and cannot be aerated evenly. [0005] Contents of the invention [0006] The purpose of the present invention i...
