Description
Technical field
The utility model relates to a kind of acoustic wave ash ejector, relates in particular to a kind of high-power Frequency Adjustable acoustic wave ash ejector.
Background technology
Acoustic wave ash ejector is a kind of equipment that compressed air is modulated into sound wave.Sound wave is inputted in boiler, can under boiler working condition, be removed the dust stratification on boiler heat-exchanger heating surface, guarantee that boiler is not because of too much blowing out of dust stratification, and can improve its thermal efficiency, play energy-conserving action.Now with acoustic wave ash ejector, mostly adopt piston type principle of sound, adopt high velocity air impact shock diaphragm to send sound wave, piston type sound wave acoustical generator is simple in structure, because of diaphragm Oscillation Amplitude limited, phonation efficiency is lower, and acoustic vibration frequency has non-adjustablely, causes that to blow grey effect undesirable.In addition, sound wave expansion is put loudspeaker and is fallen short of, and horn mouth is also large not, causes sound amplifying power limited, contains a large amount of radio-frequency components in sound wave, and the diffraction effect to sound wave in boiler impacts.
Utility model content
Therefore,, for effectively addressing the above problem, main purpose of the present utility model is to provide a kind of high-power Frequency Adjustable acoustic wave ash ejector.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of high-power Frequency Adjustable acoustic wave ash ejector, comprise frame, air accumulator, motor, casing, sounding rotor, elbow, acoustic waveguide tube, in described casing, be provided with sounding rotor and elbow, described casing is provided with casing sounding mouth, described air accumulator is fixed on frame upper end, described elbow big opening end is connected with described air accumulator openend, and described elbow osculum end is aimed at circular hole on sounding rotor, and described acoustic waveguide tube is connected on described casing sounding mouth.
Best, described elbow osculum end, described sounding rotor, described chassis cavity, described acoustic waveguide tube osculum end form a sounding chamber.
Best, described elbow is reducing elbow, and described elbow big opening end is connected with air accumulator openend, and described elbow osculum end is aimed at casing sounding mouth.
Best, described acoustic waveguide tube from inside to outside diameter increases gradually, curved horn-like.
Best, its sounding rotor is cup-shaped.
Best, described motor connects sounding rotor.
Best, described motor is the adjustable motor of rotating speed.
Best, described casing sounding mouth is shaped as circular hole shape.
Best, described air accumulator is provided with compressed air inlet.
Best, described acoustic waveguide tube is connected with and blows grey head.
The utility model beneficial effect is: adopt rotor formula vocal structure, by the switch hole cutting high velocity air sounding on rotor, it is high that this kind of vocal structure has phonation efficiency, the feature that power output is large, and sound pressure level can reach 155 decibels.Equipment motor speed is adjustable, thereby audible frequency is adjustable, can effectively adapt to boiler internal space structure, guarantees Chui Huiwu dead angle, boiler internal space.Sound wave sounding dish is cup-shaped structure, can effectively prevent the generation of mechanical bite.
