Abstract
The invention provides an axial-flow inverted umbrella aerator which comprises a driving device, an output shaft and an aeration impeller. The driving device is connected with the aeration impeller through the output shaft and drives the aeration impeller to rotate, the aeration impeller comprises an impeller shaft, a key, an axial-flow blade hub, axial-flow blades, limiting nuts and aeration blades. Water with less oxygen content at the bottom of an aeration tank can be lifted and circulated upwards by the aid of the axial-flow blades, a gas phase of oxygen is transferred into a liquid phase, so that the oxygen and the water are sufficiently and uniformly mixed, the heights and the angles of the axial-flow blades can be adjusted by adjusting positioning screws and adjusting screws according to the height of a liquid level and medium characteristics, and the functions of the aerator are sufficiently played.
Description
Technical field
The present invention relates to biological sewage treatment equipment, particularly a kind of axial-flow type inverted umbrella-shaped aeration machine.
Background technology
Aerator is the key equipment of feedwater Biological Pretreatment, biological sewage treatment.Traditional inverted umbrella-shaped aeration machine, by the rotation of aeration impeller, soluble in water for the oxygen in air.Aeration impeller produces hydraulic jump when water surface rotates, and a large amount of water droplet and sheet-like water shield are thrown in the air, and water fully contacts with air, makes oxygen dissolve in water body.The aerobic process of current inverted umbrella-shaped aeration machine, due to structure, is confined to water surface, fully mixes the object of oxygenation in order to reach aeration tank, must adopt other fluid machines, forms effective current.
How while oxygenation, under the prerequisite not increasing other equipment, the effect of being rotated by type down-umbrella aerator impeller, is promoted water body few for pond bottom oxygen level and upwards circulation, constantly oxygenation; Completing the gas phase of oxygen to liquid phase transfer, and mix with water body is full and uniform, to improve service efficiency and the dissolved oxygen rate of aerator, is the technical task being badly in need of at present solving.
Summary of the invention
For the deficiencies in the prior art part, the invention provides a kind of axial-flow type inverted umbrella-shaped aeration machine, the aerobic process that can overcome existing inverted umbrella-shaped aeration machine is only limitted to the problem of water surface, realizes the upwards lifting of aerobic process mid-deep strata water body, improves service efficiency and the dissolved oxygen rate of aerator.
For achieving the above object, the technical solution used in the present invention is:
Axial-flow type inverted umbrella-shaped aeration machine of the present invention, comprise drive unit, output shaft, aeration impeller, drive unit is connected with aeration impeller by output shaft, and drive aeration impeller to rotate, described aeration impeller comprises, impeller shaft, key, axial blade wheel hub, axial blade, stop nut and aeration blade.
