Connecing, sonic generator body side is provided with front apron, and rotating ring dish is placed in and is connected with sonic generator body seal by front apron
In the cavity of rear formation, power transmission shaft one end is connected by sonic generator main body and rotating ring dish are fixing, the other end and frequency control
Motor is fastened on sonic generator base.
As preferably, described front apron top is provided with voice tube, and voice tube is connected with sound wave amplifier, sonic generator
Body top is provided with stationary ring mouth, and rotating ring dish is provided with multiple rotating ring mouth, and air inlet pipe end big with air inlet elbow is connected, air inlet elbow
Small end is directed at sonic generator body top stationary ring mouth as blowing mouth and is tightly connected.
It is further described that the central point of air inlet elbow small end blowing mouth, stationary ring mouth, rotating ring mouth, voice tube is at same axis
On.
The center of circle of the multiple rotating ring mouths on rotating ring dish is evenly distributed in and occurs with sound wave with the center of circle of rotating ring dish for the center of circle
On the circumference that distance is radius of the central point of device main body and the central point of stationary ring mouth, the spacing between each rotating ring mouth is more than quiet
The diameter of collar extension.
As preferably, the diameter of described air inlet elbow small end blowing mouth is more than the diameter of stationary ring mouth, and air-flow is the most sufficient uniformly
Pass through generator.
This utility model has the beneficial effect that this utility model compared with prior art, rational in infrastructure, energy conversion efficiency
Height, soot blowing is effective, Frequency Adjustable, fully compressed-air actuated energy is converted to acoustic energy, improves decibels, preferably by acoustic energy
It is converted into mechanical energy to blaze abroad, overcomes diaphragm type and the design defect of resonant cavity type acoustic wave ash ejector, and diaphragm type sound wave
The mechanical and physical performance defect of soot blower.After this utility model improves, performance safety is reliable, and service life is long, can improve boiler
Efficiency, makes safe operation of the boiler, and acoustical and thermal is effective, reduces environmental noise pollution.
