Embodiment Construction
[0028]Considering the resonance performance of the transducer, the operating strategy of multi-band combined search, capture, and control to lock the optimal processing frequency is adopted, and synchronous frequency sweep is performed on each frequency band defined by the upper and lower limit frequencies. The form can be manually defined, and can also be automatically and continuously connected. In each frequency band, by monitoring the concentration of the treatment liquid action area and using program calculations, the dynamics of concentration changes are obtained synchronously in the setting mode, and the optimal process frequency point is determined according to the dynamics.

In order to make up a defect of a traditional single frequency ultrasonic wave in biological treatment application, the invention adopts an operation strategy of combinatorially searching, catching, controlling and locking an optimum treatment frequency by multiband treatment groups, each treatment group is configured with a set of treatment slot tank, a detecting device thereon, an ultrasonic power supply and a transducer-amplitude changing rod (-tool head) vibrator, and synchronous frequency sweep is carried out on an upper limiting frequency defined frequency band and a lower limiting frequency defined frequency band through controlling (the functions of generally controlling, displaying and operating parameter setup and the functions of giving frequency sweep modes and power) terminalcoordination and control; and the upper limiting frequency and the lower limiting frequency and the frequency sweep modes of the frequency bands of each treatment group can be manually set or automatically and continuously connected by referring to the inherent frequency of the transducer, so that the stain, the pollutant and the dirt on the surfaces of various biological cells and articles can receive the ultrasonic action of a proper frequency and are locked on the frequency, thereby doubly improving the treatment efficiency.
Description
Technical field [0001] The invention relates to an ultrasonic biological treatment method. Background technique [0002] The existing ultrasonic biological treatment method is: by setting or selecting a certain working frequency of the ultrasonic generating equipment in advance, and then using the ultrasonic frequency of this frequency to act on the treatment object. However, the processing rate of ultrasonic waves on objects is highly correlated with ultrasonic frequency, and the processing efficiency varies greatly with different ultrasonic frequencies; moreover, the type of biological cells to be processed is highly related to ultrasonic frequency, and different biological cells are sensitive to different frequency ultrasonic waves. very different. This has caused the blindness of the initial ultrasonic frequency determination in the existing ultrasonic biological treatment method, and further, the additional ultrasonic frequency analysis and determination form dependenc...
