Problems solved by technology

[0002] The current air-water diversion device of the aerator does not consider that the water flow formed by the propeller driven by the motor is in a vortex state in a limited area, so the design of the water outlet does not consider minimizing the kinetic energy loss in the tangential direction of the air-water mixed vortex. As a result, the speed of the air-water mixed flow at the outlet is affected, which in turn affects the service area of ​​the aerator
In addition, due to its integral design, it is not conducive to mold opening, which is not conducive to large-scale injection molding production

Abstract

Along the circumference of lower port on top of flow guiding installation, there are more than three half-ejector are opened and set along super edge vortex tangent direction, the intersection angle between surface of each ejector and column surface at top of flow guiding installation 2 is larger than 90 deg. there are more than three half-ejector are opened and set along super edge vortex tangent direction along the circumference of bottom lid of flow guiding installation, there is a protuberant conicalness at center of lower part of the flow guiding installation, inwalls of each half-ejector is narrowed to a vertebral angle Y from outside to inside, screw holes at side of half-ejector at top of flow guiding installation and at bottom lid of flow guiding installation are combined together by screw bolt. Serving area, dissolved-oxygen ratio and performance of aeration machine is increased by this invention.

Description

Technical field [0001] The invention relates to a device for mixing gas and liquid, in particular to an air-water guide device for an aerator. Background technique [0002] The current air-water diversion device of the aerator does not consider that the water flow formed by the propeller driven by the motor is in a vortex state in a limited area, so the design of the water outlet does not consider minimizing the kinetic energy loss in the tangential direction of the air-water mixed vortex. As a result, the speed of the air-water mixed flow at the outlet is affected, which in turn affects the service area of ​​the aerator. In addition, due to its integral design, it is not conducive to mold opening, which is not conducive to large-scale injection molding production. Contents of the invention [0003] The object of the present invention is to provide an air-water guide device for an aerator with multiple nozzles facing downwards, the nozzles are along the tangential directi...
