Abstract
The utility model relates to a sound wave generator which is used for the field of removing dust, washing and drying. The technical characteristic is that the upper part of the wall of a transducing cavity body whose side is corresponding to a gas inlet is provided with a guide pipe whose one end is a taper; the taper end head of the guide pipe is inserted into the transducing cavity body. A stock valve core which is arranged on the gas inlet can close the gas inlet. A valve rod is extended out the transducing cavity body by the guide pipe, and a top pressure spring cover or a hook spring cover is arranged on the valve rod. The upper part of a motor shaft is sheathed with a cam whose outer ring surface is contacted with the end head of the valve rod. The utility model has the advantages of simple structure, long service life, reliable operation and high conversion rate for sound energy.
Description
The utility model relates to a kind of sound wave generating device that sends infrasound or low-frequency sound wave, particularly a kind of being applied to mainly is made up of the transducing cavity that has air inlet and blast pipe on support body, the motor that support body one side is set, the fixing bracket body in dedusting cleaning and the dry field.
Be used to remove the dust stratification on the positions such as boiler furnace, flue, heat exchanger and the sonic generator of slagging scorification at present, mainly by the transducing cavity that is provided with gas access and gas discharge outlet and the rotating disc that is arranged on the gas discharge outlet place and has an eccentric through-hole with the motor coaxle rotation formed, infrasound and low-frequency sound generator as Chinese patent 89200617 adopt above-mentioned version exactly.Though this sonic generator can send infrasound or low-frequency sound wave by the SIN function rule, but since the sound wave of this waveform to the impulsive force of dust stratification, slagging scorification a little less than, cause dust removing effects not ideal, go back simultaneously owing to enter the interior compressed air of transducing cavity big, this just very difficult sealing that guarantees the transducing cavity of positive pressure, send intensity thereby also reduced sound wave to positions such as its rotating shafts.
The purpose of this utility model provides a kind of infrasound that sends the high sound intensity pulse or low-frequency sound wave and makes its dust removing effects become more desirable sound wave generating device.
The purpose of this utility model is exactly to realize by following technical measures; Be taper and its tapered end inserted conduit in transducing cavity stopping on the wall with the transducing chamber of air inlet institute respective side, a termination is set, and setting can be with the gas valve core that has valve rod of its involution on air inlet, and this valve rod stretches out outside the transducing cavity by conduit, but the spring cup of roof pressure or hook spring is set, the contacted cam of suit one outer ring surface and valve rod termination on motor shaft on the valve rod.
After being entered in the transducing cavity by air inlet, make the gas carrier wave produce pulsed sound, folding frequency, Compressed Gas Compressed Gas or when being lower than 400 ℃ superheated vapor and being added to air inlet, by the Electric Machine Control gas valve core radiate by discharge pipe.In the technical program,, regulate the frequency that rotating speed of motor can change sound wave if change the waveform that the shape of cam can change sound wave.
Because the utility model is provided with the cone-shaped end conduit with guide functions on the transducing cavity, thereby has reduced air-flow to the axial malleation between conduit and valve rod, has improved the sealing property of transducing cavity, has realized sending the purpose of high-strength poop type sound wave.The utlity model has simple in structure.The advantage that life-span is long, reliable and the acoustic energy conversion ratio is high.
Accompanying drawing is a structural representation of the present utility model.
Be described in further detail below in conjunction with the technical characterictic of accompanying drawing the utility model most preferred embodiment.
It is a kind of that { 8}, the motor of support body one side is set, and { { { 13} changes the cavity { sound wave generating device that 10} formed for 12} and blast pipe to have air inlet on the 3} fixing bracket body by support body.
With the transducing cavity wall of air inlet institute respective side on, a termination is set is taper and its cone-shaped end inserted conduit { 9} in transducing cavity, and on air inlet, be provided with can be with its involution have the valve rod { gas valve core { 11} of 7}, and this valve rod stretches out outside the transducing cavity by conduit, but roof pressure or hook spring { spring cup of 6} { 5}, the contacted cam { 1} in suit one outer ring surface and valve rod termination on motor shaft are set on the valve rod.
In order further to improve the conversion efficiency of this device, reduce the flowed energy loss that causes because of guiding, thereby the inner chamber of this transducing cavity is taper barrel, gas valve core adopts conical structure.
In the present embodiment, in order to reduce the frictional dissipation between cam and valve rod, the runner shaft of being furnished with of one " U " type is set in the valve rod termination, and { { 4} is provided with its outer ring surface and the cam outer shroud runner { 2} of closing mutually to the 4} rotary wheel frame on changeing.
Claims (3)
1. sound wave generating device of being formed by the transducing cavity that has air inlet and blast pipe on support body, the motor that support body one side is set, the fixing bracket body, it is characterized in that with the transducing cavity wall of air inlet institute respective side on, one termination is set is taper and its cone-shaped end is inserted the conduit of transducing chamber in stopping, and setting can be with the gas valve core that has valve rod of its involution on air inlet, and this valve rod stretches out outside the transducing cavity by conduit, but the spring cup of roof pressure or hook spring is set, the contacted cam of suit one outer ring surface and valve rod termination on motor shaft on the valve rod.
2, sound wave generating device according to claim 1, the inner chamber that it is characterized in that this transducing cavity is a taper barrel, gas valve core adopts conical structure.
3, sound wave generating device according to claim 1 and 2 is characterized in that being provided with in the valve rod termination rotary wheel frame of being furnished with runner shaft of one " U " shape, and its outer ring surface and the cam outer ring surface runner of closing mutually is set on runner shaft.
