Summary of the invention
The utility model provides that a kind of cost is low, long service life and result of use are good, can realize the stirring aerator of plug-flow, aeration and stirring.
In order to reach above technique effect, the technical solution adopted in the utility model is as follows:
A kind of stirring aerator comprises drive unit, shaft coupling, intermediate support seat, housing, transmission shaft, underwater bearing apparatus and impeller;
Be connected by described intermediate support seat between described drive unit and the described housing;
Described shaft coupling is arranged on the central shaft of described intermediate support seat, and is connected with described drive unit and described transmission shaft;
Described transmission shaft is open tube, and the wall thickness of described open tube is 16-20mm, and described open tube is provided with the first inlet mouth;
Described transmission shaft is arranged on the central shaft of described housing, and forms inlet plenum with the inwall of described housing, and described housing is provided with the first inlet pipe;
Described underwater bearing apparatus is arranged on the described transmission shaft, and is arranged on the place ahead of described inlet plenum, and and described inlet plenum between separate fully by flange;
Described underwater bearing apparatus is demountable structure;
Described impeller is arranged on the described transmission shaft.
Preferably, described shaft coupling is the gimbal coupling with needle roller structure.
Preferably, described drive unit is motor.
Preferably, the wall thickness of described open tube is 18mm.
Therefore the technical scheme of application the utility model embodiment stirs aerator and is provided with dismountable underwater bearing apparatus, separate fully with inlet plenum, increase the inflow-rate of water turbine that external agency enters sliding surface bearing, it is lubricated more reasonable to make, the work-ing life of greatly improving bearing; Stir aerator and be provided with the intermediate support seat, the load that produces when making impeller work is all born the error of removable universal energy-saving compensated concentricity by it; Stir the open tube that aerator is provided with heavy wall, as transmission shaft, intensity is high, and has larger source mill's surplus, and the transient equilibrium of axle is better, noise and vibrate little during the complete machine operation.Stir aerator when operation, the impeller of rotation has formed a stronger negative pressuren zone in its peripheral region, thereby with air intake, the air that sucks by the liquid of high rapid-result rotation strongly shear, pulverizing, emulsification, bubble diameter reduces rapidly, impels oxygen molecule to diffuse to the liquid phase rapidly, fully from gas phase, realize that best aqueous vapor is synthetic, water, gas are pushed ahead under powered simultaneously, and water, gas are further melted, and reach the purpose of aeration and stirring plug-flow; Because dissolved oxygen rate is high, and can realize simultaneously three kinds of functions, alternative traditional oxygenating device or stirring flow pulling equipment, operation and maintenance can be saved 1/4～1/3 expense.
