Example Embodiment

[0016] The invention provides an ultrasonic transducer device for liquid treatment. Such as figure 1 As shown, it is a schematic diagram of the first embodiment of the present invention. The liquid processing ultrasonic transducer includes at least one ultrasonic generator (not shown), a transducer 3, and a vibrating tube body 1 containing liquid. One end of the vibrating tube body 1 is provided with an opening 11, and the other end is equipped with a transducer 3, which is a longitudinal vibration transducer that can convert the ultrasonic waves generated by the ultrasonic generator into longitudinal high-energy mechanical vibration . The transducer 3 is fixedly connected to the vibrating tube body 1 by welding, which can just close the end of the vibrating tube body 1. The transducer 3 is electrically connected to the ultrasonic generator through a cable 7. A sleeve body 40 capable of accommodating the transducer 3 is also provided on the outside of the transducer 3, the upper ...

Abstract

A transducer method for ultrasonic liquid treatment, in which a first transducer and a second transducer are respectively arranged at both ends of a vibrating pipe body, and the length of the vibrating pipe body is selected as the working frequency of the first transducer and the second transducer Corresponding to an integer multiple of the equivalent half-wavelength, the axial vibration of the first transducer and the second transducer is converted into radial vibration, and the ultrasonic energy is converged in the tube to apply strong ultrasonic energy to the liquid in the tube. The transducer device for ultrasonic liquid treatment includes a vibrating tube body, a first transducer, a second transducer arranged at both ends of the vibrating tube body, and an ultrasonic generator for driving the transducer. The vibrating tube body can convert the vibration generated by the transducer along the axial direction of the vibrating tube body into vibration along the radial direction of the vibrating tube body, so that the ultrasonic energy can concentrate on the liquid in the tube. The device of the present invention has simple equipment structure, high reliability and convenient use, and can be widely used in the fields of object cleaning, emulsification, crushing, sonochemistry, extraction of Chinese herbal medicines, bioengineering and the like.

Description

technical field [0001] The invention relates to ultrasonic technology, in particular to an ultrasonic transducer method and device for liquid treatment. Background technique [0002] At present, ultrasonic treatment technology is widely used, including cleaning, emulsification, crushing, sonochemistry, extraction of Chinese herbal medicine and bioengineering and other fields. In the application of liquid treatment such as ultrasonic cleaning and sonochemistry, how to generate the required ultrasonic wave is the key to the technology. Therefore, people are constantly developing various transducers. Its function is to convert the high-frequency electrical signal generated by the ultrasonic generator into High-frequency mechanical vibration energy is emitted into the liquid medium, causing physical effects such as "cavitation" in the liquid. At present, the commonly used ultrasonic groove treatment is to stick the transducer on the bottom or side of the groove, or install the ...
