Description
Technical field
The utility model relates to a kind of ultrasonic radiator, particularly relates to the high power longitudinal footpath complex vibration ultrasonic radiator of the focusing of a kind of liquid handling or all-directional ultrasonic radiation.
Background technology
Along with the extensive use of ultrasonic technique in fields such as industry, chemical industry, environmental protection, pharmacy, oil-gas field developments, Power Ultrasonic Vibration System is had higher requirement: high efficiency, high-power and continous-stable work.Current, in the large power supersonic application, power density is large, electromechanical conversion efficiency is high and steady performance because extensional vibration sandwich PZT (piezoelectric transducer) has, and it is most widely used.But because the theory of extensional vibration sandwich PZT (piezoelectric transducer) own and structure are limit, have the following disadvantages:
The extensional vibration sandwich transducer can only be realized the single direction radiation of ultrasonic energy, and namely the radianting capacity of transducer is along its y direction substantially, can not realize 360 degree space omnidirectional radiation of ultrasonic energy.
The design theory of extensional vibration sandwich transducer require the lateral dimension of transducer can not surpass the radiation of transducer institute wave length of sound 1/4th, therefore the acoustic radiation area of extensional vibration sandwich transducer is subject to the restriction of self theory, has greatly limited acoustic irradiation power and the electro-acoustic conversion efficiency of extensional vibration sandwich transducer.
In order to improve ultrasonic radiation power, increase the scope of ul-trasonic irradiation, traditional method is to adopt the mode of structuring the formation, and namely a plurality of sandwich transducers is bonded on the corrosion resistant plate, forms vibration plate.When the amount that requires to clean or process is larger, need to increase vibration plate, at this moment need sticking dozens or even hundreds of transducer on vibration plate, sometimes even adopt a plurality of vibration plates to satisfy large volume ultrasonic cleaning and processing requirements.For this mode, because the swept area of each transducer is little, cause efficient not high, equipment is huge, and poor stability uses inconvenience.Therefore the ultrasound transducer means of vibration plate form is difficult to satisfy the requirement of plant-scale ultrasonic cleaning and processing.
In addition, for the radiant power that improves traditional longitudinal ultrasonic vibrational system and improve the acoustic irradiation direction, people have proposed the circular pipe type ultrasonic radiator.As: the patent No.: ZL 200510033810.8, name is called " ultrasonic liquid is processed energy-changing method and device ", by the one or both ends at the cylindrical shape liquid container transducer is set, makes the axial vibration of transducer convert radial vibration to and reach the purpose that liquid in the cylinder is applied ultrasonic energy.This ultrasonic radiator excites the high frequency extensional vibration of cylinder by the extensional vibration of transducer, utilize poisson effect to realize the radial ultrasonic radiation of cylinder, thereby improved the acoustic irradiation direction of compressional vibration sandwich transducer and increased the ultrasonication area, but also had following deficiency:

(2) vertical driving sandwich transducer of this ultrasonic radiator directly is connected by modes such as welding with metallic cylinder, the diameter that the radial dimension of transducer has limited metallic cylinder is difficult to accomplish larger, therefore the ultrasonication area of this radiator also is limited by the radial dimension that drives transducer, and the liquid of processing in cylinder is also relatively limited.In addition, in order to increase the ultrasonic radiation area of cylinder, the way of length that can be by increasing cylinder realizes, but the length of cylinder is longer, (frequency one regularly corresponding to the humorous frequency vibration of vertical high order of high-order more for the extensional vibration of cylinder under the same stimulating frequency, half-wavelength of the every increase of the length of cylinder, the vibration order increases single order), under the certain condition of vertical stimulating frequency of transducer and power, the radial vibration that the high-order longitudinal harmonics of cylinder utilizes poisson effect to produce with respect at a low price vertical harmonics is inevitable more weak, therefore under the more high-order longitudinal vibration pattern of cylinder the radial radiation sound wave in the pipe also a little less than, it is very large that this longitudinal size that has also limited cylinder can not be done.
In the prior art, in order to obtain preferably radial vibration mode, usually adopt piezoelectric ceramic circular tube and metal circular tube to nest together by the method for heat expansion and cold contraction and realize whole radial mode vibration.The patent No. is ZL 200520075667.4, name is called the utility model patent of " high power altrasonic transducer ", adopt multistage short pipe PZT (piezoelectric transducer) unit with the metal stressed shell vertically the machinery serial connection form, this transducer can obtain preferably radial vibration mode, but following deficiency is arranged:
(1) radial vibration of transducer is that 3-1 coupling by the piezoelectricity pipe realizes its transverse electromechanical coupling factor
k 31Less, thereby the electromechanical conversion efficiency of transducer is lower.
(2) the metal stressed shell nests together the unidirectional radially prestressing force that piezoelectric ceramic circular tube is applied ecto-entad with the piezoelectric ceramic tube of inside by the method for heat expansion and cold contraction, the size of this prestress application is difficult to control, the power capacity of the too little transducer of prestressing force is restricted, power density is less, and prestressing force is crossed conference and caused that piezoelectric ceramic tube is broken.In addition, the interior electrode (wire) of this transducer directly is welded on the coating electrode face of piezoelectric ceramics inside pipe wall, is " point " contact between the two, and when the transducer input electric power was larger, strong vibration caused that easily high voltage arc and electrode come off.
For the prestressing force that overcomes the above-mentioned radial compound transducer of realizing by the nested technique of expanding with heat and contract with cold is difficult to regulate control and the lower deficiency of electromechanical conversion efficiency, the patent No. is ZL 200910102269.X, name is called the utility model patent of " a kind of large power supersonic multiple tube ", the arc piezoelectric ceramic piece of employing multi-disc thickness polarization in the circumferential direction of the circle evenly distributed circularizing consists of cylinder piezoelectric ceramic stack ring group, be provided with the metal stressed shell in cylinder piezoelectric ceramic stack ring group outside, the inboard is provided with the expanding prestressing mechanism, inner expanding prestressing mechanism applies the suitable radially compressive pre-stress that can regulate control with outside metal stressed shell is collaborative to cylinder piezoelectric ceramic stack ring group, thereby the power capacity of Effective Raise cylinder piezoelectric ceramic stack ring group, and the radial vibration mode of this ULTRASONIC COMPLEX pipe is that the thickness vibration mode by the cylinder piezoelectric ceramic stack ring group of thickness polarization excites, its thickness electromechanical coupling coefficient kt is higher more than 40% than the transverse electromechanical coupling factor k31 of piezoelectric ceramics pipe, has significantly improved the data-collection ability of piezoelectric ceramics.Although this large power supersonic multiple tube all increases in structure and performance ratio piezoelectric ceramic circular tube formula composite transducer in the past, also come with some shortcomings and need to improve and improve part:
(1) complicated structure of composite ultraphonic pipe, complicated with respect to traditional its processing technology thereof of sandwich PZT (piezoelectric transducer).
(2) building block of formation multiple tube is more, the structure of each part and dimensional parameters all consist of impact to the performance of multiple tube, factor and the variable that need to consider during design are more, its manufacture craft also needs continuous improvement and perfection simultaneously, such as shared ratio of control, each part of prestressing force size etc.
