Abstract

The invention belongs to the technical field of ultrasonic cleaning, in particular to a double-tank ultrasonic cleaner based on a bidirectional ultrasonic radiation recombination transducer. The double-tank ultrasonic cleaner comprises a bidirectional radiation transducer, wherein a front radiation surface and a rear radiation surface of the bidirectional radiation transducer are bonded with a first cleaning tank and a second cleaning tank respectively, and the bidirectional radiation transducer comprises piezoelectric chips, front metal tapered radiation blocks and rear metal tapered radiation blocks. By changing the front and rear metal radiation materials of the bidirectional radiation transducer, different sound radiation power can be generated in the two cleaning tanks of ultrasonic cleaner; by changing the geometric shapes of the front and rear metal radiation materials of the bidirectional radiation transducer, ultrasonic radiation of different strength can be generated; and with the additional design of the bidirectional radiation transducer, the problems of ultrasonic reflection and impedance mismatching are solved, and the radiation efficiency and power of the bidirectional radiation transducer are improved and increased greatly. The double-tank ultrasonic cleaner has the advantages of low energy dissipation, and high radiation power and radiation efficiency, and deserves to be popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic cleaning, and in particular relates to a double-slot ultrasonic cleaner based on a bidirectional ultrasonic radiation composite transducer. Background technique [0002] Ultrasonic cleaning is to use the cavitation effect, acceleration effect and acoustic flushing effect of ultrasonic waves in liquid to directly and indirectly affect liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. Among the currently used ultrasonic cleaning machines, cavitation and acoustic flushing are more widely used. Ultrasonic cleaning is widely used in surface spraying treatment industry, machinery industry, electronics industry, medical industry, semiconductor industry, watch and jewelry industry, optical industry, Textile printing and dyeing industries. [0003] The principle of the ultrasonic cleaning machine is as follows: the high-frequency oscilla...
