Detailed description of the invention
Embodiment one:
The present embodiment is a kind of efficient anti-bite frequency conversion sonic wave ash cleaner, as shown in Figure 1。The present embodiment includes: be arranged on the motor 2 on base 1, the rotating shaft of described motor is connected with rotation dish 3, described rotation dish is surrounded by pressure stabilizing cavity shell 4, described pressure stabilizing cavity housing is provided with compressed air inlet 5 and sounding mouth 6, described sounding mouth is connected with acoustic waveguide tube 7 and sleeve 8 successively, described rotation dish is along the uniform multiple sounding chamber 301(of excircle as shown in Figure 2), described sounding chamber is the breach that rotation dish radially extends to rotation dish excircle, and described sounding mouth is arranged on the position that the diametric(al) of rotation dish is corresponding with sounding mouth。
The ultimate principle of the present embodiment is: compression air is filled with pressure stabilizing cavity, is have certain air pressure in pressure stabilizing cavity。The sole outlet of the air in pressure stabilizing cavity is sounding mouth。Rotation dish is provided with along periphery and multiple is called sounding chamber groove, makes rotation dish being shaped like in gear on the cross section vertical with rotating shaft。Gap only only small between periphery and the sounding mouth of rotation dish, so the periphery of rotation dish is substantially has blocked sounding mouth, but when being spiraled in the position forwarding groove in rotation, sounding mouth is opened, compression air can flow out pressure stabilizing cavity through sounding mouth, the direction of arrow B in as shown in Figure 2。Owing to rotation dish quickly rotates in (in Fig. 2 the direction of arrow C), the outspoken speed of sounding either on or off repeatedly, rotation dish constantly quickly cuts the air-flow at sounding mouth place, makes air produce vibration at sounding mouth, namely creates sound。The sound produced, in the exaggerated and output of waveguide and sleeve, eventually becomes the sound wave of comparatively strong air vibration, and utilizes the shock effect of sound wave to remove the dust piled up on flue and filter。
The present embodiment air is the Radial Flow along rotation dish。Compared with existing axial-flow type sound wave ash cleaner: owing to sounding mouth is arranged on inner headed face, and sounding chamber is arranged on periphery, and axle, hole are as the workpiece easily realizing precision-fit is prone to processing, reduce cost, also has automatic cleaning action, effectively prevent the generation rotating reel bite, thus greatly reducing the fault rate of equipment, the service life of extension device。Owing to the present embodiment air is Radial Flow, the both sides end face of rotation dish is all pressure stabilizing chamber, and this just makes the volume of pressure stabilizing chamber add nearly one times, and the sound wave of generation is more stable。
For producing to stablize suitable air vibration, the gap between rotation dish cylindrical and sounding mouth should control in more accurate scope, as: 0.1 ~ 0.2mm。
Compression air enters pressure stabilizing chamber by import, subsequently into sound wave maker, air-flow is cut into sine wave and forms sound wave by the rotation reel structure in sound wave maker, and sound wave amplifies through the modulation of hyperbolic acoustic waveguide tube, expand reference frequency output, effectively raise radiation efficiency。
Deashing needs the vibrations of different frequency, to cause the resonance of different size of dust granule, in order to dust out。The present embodiment can change the frequency of acoustic wave vibrations by changing the rotating speed of rotation dish, and changes the rotating speed of rotation dish, it is possible to realizes by changing the rotating speed of motor。Therefore, motor can use common frequency control motor, it is possible to use motor that adjusting speed accuracy is higher or servomotor。
The effect of pressure stabilizing cavity is to utilize certain space, and modulation enters the compressed air pressure of pressure stabilizing cavity, and gets rid of due to the air vibration of sounding mouth, and the pressure of generation is unbalanced。Being sounding owing to being runoff, therefore, rotation dish both sides are all arranged as pressure stabilizing cavity, increase the space of pressure stabilizing cavity。
Rotation dish is round-disk shape workpiece, and periphery has multiple groove as sounding chamber。The cross sectional shape vertical with rotating shaft of rotation dish is similar to gear, and the bottom of groove can be circular or other shapes。The diameter compatible of the width of groove and sounding mouth closes, namely equal or smaller。The quantity of groove is typically in 8 ~ 10, to produce the vibrations sound wave of 70～800Hz radiation frequency, the granular size of its frequency deashing as required and determine。
The main effect of acoustic waveguide tube is to be passed by the air vibration produced at sounding mouth, and plays certain amplification, and therefore, acoustic waveguide tube can adopt the shape of enlarging, and its revolution bus adopts the hyperbola being beneficial to sound wave transmission and amplification。Acoustic waveguide tube can adopt casting metal material。
The effect of sleeve is mainly amplification, also undertakes the effect of transmission vibration sound wave。Therefore, sleeve should adopt the material utilizing vibration, the sound of the close output of its frequency of vibration, in order to produce resonance。The material of sleeve can select the various sheet metal being prone to produce resonance。For making resonance strong, the revolution bus of sleeve can also adopt hyperbola。
