Ultrasonic dispersion machine signal generator to generate high-frequency signals, the frequency and the frequency of the ultrasonic immersion tank, the electrical signal drive after preamplifier composed of power module power amplifier, ultrasonic sonochemistry machine after power amplification by the output transformer coupling to the impregnating tank, ultrasonic dispersion machine produced by ultrasonic. Magnetic power provided to the magnetostrictive transducer work necessary to offset current.
Ultrasonic dispersion machine using ultra strong vibration energy evenly, can effectively to ultrasonic processing of all kinds of liquid and mixed liquid, in order to achieve homogeneous, dispersion, emulsification, crushing, catalysis, etc. Generator panel has a power switch, power adjustment knobs, frequency adjustment knobs, alarm indicator light and power displayed voltmeter. Frequency adjustment knobs for boot is to adjust the resonance frequency of the dipping machine; Power control knobs allows users to choose the output power, according to need to obtain a satisfactory treatment effect. When the generator failure or improper use, user should immediately disconnect the PWM output signal and the working power supply, the alarm indicator. The main part of ultrasonic processing tank for ultrasonic transducer. This kind of transducer composed of rare metal material sintering, through special processing of wound coil material to pass on the high frequency signal, to a certain magnetizing current, under the action of longitudinal stretching vibration, through the energy transfer, the vibration energy into the process tank. Ultrasonic dispersion machine power regulation by thyristor voltage regulation circuit dc voltage regulating power amplifier unit. Use detection circuit monitor the operation condition of power amplifier, once and set data does not ultrasonic dispersion machine conform to the protection circuit will work, cut off the dc voltage power amplifier unit and shut down the output of the oscillator. So that can effectively protect the ultrasonic generator power amplifier parts from being damaged.
Under normal circumstances, in order to be able to make to the working conditions of ultrasonic dispersing, often can make the rotor and stator are in relatively high speed motion state. The shear flat rate between tooth and tooth flat rate than the sound waves. Ultrasonic dispersion machine in the system, while the difficulty of the test the phenomenon it is necessary to directly, but the actual result has been achieved. It is equivalent to what the ultrasonic device. High-speed movement technology accelerates a craft materials and fluid to achieve strong turbulence, thus achieve needed to achieve the purpose of in the industrial process. Because of the need to the technology of high-speed movement. Can be scattered material between rotor and stator is strong again without the shear cracks, eddy current, the leakage of the extrusion, etc., thus to decrease grain and uniform dispersion, such as the good contact between phase and phase effect. Also because of the high speed movement technology, materials processing time than the traditional way of dispersed a lot less.
Ultrasonic dispersion machine driven by ultrasonic vibration components and special ultrasonic power and reaction kettle of three parts: ultrasonic vibration parts mainly include the high power ultrasonic transducer, luffing rod, tools, used to generate ultrasonic ultrasonic dispersing machine vibration, and the vibration energy to launch in the liquid. Transducer input electrical energy into mechanical energy, ultrasonic wave. The form is the transducer in longitudinal slip movement back and forth, amplitude generally within a few microns.
So the amplitude of the ultrasonic dispersing power density is not enough, can't be used directly. According to the design needs to enlarge the amplitude, the amplitude segregation reaction solution and the transducer, but also have the effect of fixed the ultrasonic vibration system. Tool head is connected with the amplitude, luffing rod pass ultrasonic vibration energy to tool head, again by the tool head would launch ultrasonic energy to chemical reaction in the liquid.
