Nomenclature:
1: aerator disk 2: back up pad 3: circular cone version 4: injection well 5: positioning screw 6: set screw nut 7: lower nozzle 8: the self-excited oscillation cavity 9: upper spray nozzle 10: spacing hole 11: solarization air cap 12: communicating pores
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1, the micro-hole aerator that a kind of self-oscillatory center is fixing, comprise aerator disk 1, back up pad 2 and injection well 3, the center of aerator disk 1 and back up pad 2 is provided with spacing hole, positioning screw 5 is fixedly installed in spacing hole, positioning screw 5 lower end arranges set screw nut 6, back up pad 2 lower end is fixedly installed conical plate 3, conical plate 3 lower end is provided with injection well 4, injection well 4 lower end is provided with lower nozzle 7, and injection well 4 upper end is provided with upper spray nozzle 9, is provided with the self-excited oscillation cavity 8 between lower nozzle 7 and upper spray nozzle 9.
The diameter of further described aerator disk 1 is 215mm-350mm, surface is provided with a large amount of solarization air caps 11 in cellular, the diameter of these solarization air caps 11 is 100 μm-120 μm, aerator disk 1 forms by quartz sand high-temperature firing bonding, back up pad 2 surface is provided with communicating pores 12, lower nozzle 7 is communicated with external gas source, and the diameter of upper spray nozzle 9 is larger than the diameter of lower nozzle 9, and the top of the self-excited oscillation cavity 8 is provided with taper impact walls.
During work, by the air that compresses through lower nozzle 7, according to hydromechanical principle, the self-excited oscillation cavity 8 chamber diameter and chamber length, lower nozzle 7 diameter, the numerical value at the pitch angle of taper impact walls, a pair collar vortex along axisymmetrical can be produced in the self-excited oscillation cavity, make collar vortex structure more reasonable, can be become stable by the air compressed, periodically concussion, the obvious air pulse of frequency range, Minimal energy loss in this course, pressurized air causes in the speed when upper spray nozzle 9 that flows out variant owing to producing velocity variations in the self-excited oscillation cavity 8, the Air Bubble Size that such pressurized air is overflowed by the solarization air cap 11 of aerator disk 1 is variant, flow velocity is variant, larger stirring action can be produced to water, increase the content of dissolved oxygen, improve aeration efficiency.
