The specific working principle of ultrasonic dispersion machine

  • 2021-10-11
The high-power ultrasonic dispersion system is composed of three parts: ultrasonic vibration components, ultrasonic drive power supply and reaction kettle: ultrasonic vibration components mainly include high-power ultrasonic transducer, horn, and tool head (transmitting head), which are used to generate ultrasonic vibration. And launch this vibration energy into the liquid. The transducer converts the input electrical energy into mechanical energy, that is, ultrasound. Its manifestation is that the transducer stretches back and forth in the longitudinal direction, and the amplitude is generally a few microns. This amplitude power density is not enough and cannot be used directly. The horn amplifies the amplitude according to the design requirements, isolates the reaction solution and the transducer, and also plays a role in fixing the entire ultrasonic vibration system. The tool head is connected with the horn, the horn transmits the ultrasonic energy vibration to the tool head, and then the ultrasonic energy is emitted into the chemical reaction liquid by the tool head.

 
The main component functions of the ultrasonic dispersion system:
1. Ultrasonic vibration source (drive power supply): convert 50-60Hz mains power into high-power, high-frequency (15kHz-100kHz) power supply, and provide it to the transducer.
2. Transducer (controller, transducer): converts high-frequency electrical energy into mechanical vibration energy.
3. Amplitude rod: connect and fix the transducer and the tool head, and transmit the amplitude of the transducer to the tool head after being amplified.
4. Tool head (introduction rod): transfer mechanical energy and pressure to the work object, and also have the function of amplitude amplification.
5. Connecting bolts: connect the above components tightly.

Main features of ultrasonic dispersion equipment
1. The equipment upgrade is simple, no need to change the customer's existing production equipment and technological process;
