Abstract
The utility model relates to an aeration head for an aeration machine, which comprises an external hub (1) which approximately forms a barrel shape and an internal hub (3) which is positioned in and is connected with the external hub by a radials, wherein the internal hub (3) is used for connecting a motor transmission shaft of the aeration machine, a hollow part between the external hub (1) and the internal hub (3) is an air duct (6), and airscrew blades (4) are circularly fixed to the periphery of the external hub (1). The utility model is characterized in that an aeration rotary head (5) which can rotate with the external hub (1) is arranged on the external hub (1) at the outlet of the air duct (6), at least two separate paws (51) are arranged at the end part of the aeration rotary head (5), and at least one aeration hole (52) which is communicated with the air duct (6) is formed in each of the separate paws (51). Because the aeration rotary head is added to the front end of the external hub of the utility model, enhanced negative pressure is formed at the end part of the aeration rotary head when airscrews rotate at a high speed to push water currents; thus, air which passes through the aeration rotary head is cut into a plurality of minute air bubbles, and then, the separate paws agitate the airscrews which rotate at high speed so as to push the strong water currents to form vortexes to cut the air bubbles once more; therefore, air bubbles formed can be fine and uniform, and oxygen enhancement efficiency can be high.
Description
Technical field
The utility model relates to the aeration head of the aerator in a kind of water treatment field, particularly a kind of aerator.
Background technology
In industries such as sewage purification, aquaculture, be used for being widely used at present to the aerator of water body oxygenation.As the patent No. is a kind of diving oxygenation aerator the Chinese utility model patent " electronic plugflow aeration machine " of ZL00219059.1 (notification number is CN2402672Y) discloses, it comprises submersible machine, impeller and inlet pipe, described impeller is made up of at least two blades, wheel hub, airway and two disc at least, blade ring is fixed around the airway outer rim, the rotation center position of wheel hub in disc is fixed on airway, wheel hub links to each other with the output shaft of submersible machine, and airway is communicated with inlet pipe and constitutes air intake passage; The negative pressuren zone that this design utilizes airway set on the impeller directly air intake passage to be formed when airway extends to impeller rotation plug-flow directly mixes collision and realizes oxygenation, thereby saved water entry and aqueous vapor exhaust channel than conventional art with current.But the bubble that this aerator produced is also thicker, and is also even inadequately, thereby causes oxygenation effect not very good.
Summary of the invention
Technical problem to be solved in the utility model is the aeration head that a kind of aerator that bubble is more tiny, even, oxygenation efficient is higher of generation is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the aeration head of this aerator includes the outer hub that roughly is tubular and is positioned at it by the coupled hub of disc, hub promptly is used for linking to each other with the motor transmission shaft of aerator in described, and the hollow bulb between outer hub and the interior hub is airway, and the hub outer rim also is fixed with blade around ground outside, the outer hub that it is characterized in that airway export department is provided with the aeration rotary head that can rotate with outer hub, aeration rotary head end is provided with at least two and disperses pawl, and has the solarization air cap that at least one is connected with airway in described dispersion pawl.
It is conical that above-mentioned aeration rotary head can preferably be, and can reduce the aeration rotary head so better when rotating and the resistance between the water.
In order to improve outer hub and the aeration rotary head stability when rotating, described dispersion pawl can be evenly distributed on the end of described aeration rotary head.
Above-mentioned aeration rotary head can be screwed onto on the described outer hub, also can be connected with described outer hub by bearing pin, specifically can decide by design requirement.
Compared with prior art, because outer hub front end of the present utility model has been set up the aeration rotary head, therefore at driven by motor water screw high speed rotating and when promoting current, form powerful negative pressure in aeration rotary head end, the suction outside air, be cut into a large amount of small bubbles when air is through the aeration rotary head on the one hand, disperseing pawl to promote strong current formation vortex by the water screw that stirs high speed rotating then cuts bubble once more, and bubble and water fully mixed, thereby make the bubble of generation more tiny, even, oxygenation efficient is higher.
