Description
Technical field
The present invention relates to a kind of sandwich type ultrasonic wave transducer front shroud assembly and the sandwich type ultrasonic wave transducer equipped with this assembly.This assembly and transducing
Device is particularly well-suited to for ultrasonic applications under fluid environment.
Background technology:
Ultrasonic transducer is the critical component that piezoelectric effect is converted into mechanical vibrational energy, is to obtain cavitation effect, thermogenetic effect, mechanical effect
Effective means, therefore ultrasound wave is widely used in catalysis, extraction, emulsifying, dedusting, cleaning, sterilizing, promotion chemical reaction etc.；Existing super
What acoustic wave transducer was the more commonly used is sandwich type ultrasonic wave transducer, and its front shroud generally has straight barrel type, broadening formation etc., and its front shroud includes protecgulum
Sheet-pile body, front shroud end face, front shroud bottom surface and front shroud bottom surface screw, front shroud bottom surface screw connects the piezoelectricity unit of rear end by stress bolt
Part, electrode slice, insulation sleeve, back shroud etc. form complete sandwich type ultrasonic wave transducer；Existing sandwich type ultrasonic wave transducer is to utilize front shroud
End face is installed, its mounting means: then applied glue by sandwich type ultrasonic wave transducer front shroud end face is close to stainless steel trough body peripheral surface
On, it is formed for connecting after glue curing；Alternative mounting means is: arrange a screw at sandwich type ultrasonic wave transducer front shroud end face,
Weld a stud matched with screw in stainless steel trough body position to be mounted, then apply glue will press from both sides at sandwich transducer front shroud end face
Heart transducer is arranged on stud, when being formed for connecting after glue curing；When ultrasonic transducer works, its ultrasonic energy produced need to pass through
Mucigel and stainless steel trough body transfer energy in stainless steel tank again, and these processes cause ultrasonic energy to lose portion of energy in transmission；Simultaneously
Often occurring that glue departs from long-term use process makes the unloaded phenomenon of transducer appearance cause ultrasound wave conduction failure；Ultrasonic transducer is long-term
The installed surface of body can be punctured formation breakage by work and cause shorten the service life of body；When ultrasonic transducer breaks down, transducer is changed
Maintenance difficulties is big；Prior art also has another kind of sandwich type ultrasonic wave transducer ultrasonic transducer as described in patent No. CN202398511U its
Front shroud is to act directly on the liquid in container, but the problem that this transducer front shroud exists installation difficulty such as to install transducing on a pipeline
Device, sealing ring first can only be arranged on front shroud top cross-sectional by this ultrasonic transducer, is then put into by transducer in pipeline again by transducer cylinder
Pull outward and make front shroud top cross-sectional form conflict with inner-walls of duct, finally nut is tightened from pipeline；The installation on pipeline of this transducer
Seem highly difficult, and there is the risk of liquid leakage in pipeline；The electrode slice carried on the most existing transducer is generally a round foil limit
Marginal zone has substantially in semi-circular union joint, and this union joint major function is to connect ultrasound wave to drive power supply, if this transducer is the form with finished product
Being arranged on container, the through hole of container is necessary for the position that or through hole bigger than transducer front shroud cylinder need to pass through with union joint, next to that its spiral shell
Female is also to need the profile matched with electrode slice could realize nut to be arranged on front shroud cylinder by electrode slice；If this transducer is with accessory
Form install and certainly will cause the problem of transducer each piezoelectric element parameter coupling after installation, this is because each transducer must be through before dispatching from the factory
Crossing precision measurement makes each parameter the most relatively mate such as Frequency point；Before acting on the sandwich type ultrasonic wave transducer typically utilization of fluid environment in sum
Cover plate transmits ultrasonic energy and utilizes front shroud to be fixed but existing transducer causes installation difficulty, machine due to the defect that front shroud exists
Body life time is shorter, ultrasonic energy loses, maintenance work difficulty；In order to obtain bigger ultrasonic power, in order to there be mounting structure more easily,
In order to make body obtain longer service life；In order to obtain the most convenient more efficient maintenance work it is therefore necessary to before to sandwich type ultrasonic wave transducer
Cover plate is improved.
