What is the working principle of ultrasonic emulsification equipment
Ultrasonic emulsification equipment uses strong ultrasound to pulverize insoluble solids (or other liquids) in liquids into particles and fully mix with surrounding liquid to form emulsions.
The physical mechanism for crushing insoluble solids (or liquids) is generally considered to be the ultrasonic cavitation effect. The ultrasonic cavitation effect means that under the action of strong ultrasonic waves, a large number of bubbles will be generated in the liquid. The small bubbles will gradually grow and increase with the ultrasonic vibration, and then suddenly burst and split. The split bubbles continue to grow and burst. . When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubbles, and strong local shock waves are generated in the liquid near the bubbles due to the liquid surrounding the bubbles rushing into the bubbles at high speed, and local high temperature and pressure are also formed, which results in Ultrasonic crushing, ultrasonic emulsification.
Product Principle
Ultrasonic emulsification equipment consists of two parts: ultrasonic emulsification component and ultrasonic drive system (ultrasonic generator).
Ultrasonic emulsification components: mainly include ultrasonic transducers, ultrasonic horns, and ultrasonic tool heads to generate ultrasonic vibrations and emit this vibration energy into the liquid.
1. Ultrasonic drive system: Generate high-frequency high-power current to drive ultrasonic vibration parts to work. The power of the ultrasonic generator is adjustable to suit different working conditions. A timing controller can also be integrated in the generator as required to set and control the ultrasonic vibration time and interval time.
2. Ultrasonic demulsification equipment consists of two parts: ultrasonic demulsification system and ultrasonic drive system (ultrasonic generator).
The ultrasonic demulsification equipment mainly includes an ultrasonic transducer, an ultrasonic horn, and an ultrasonic tool head for generating ultrasonic vibration, and transmitting the vibration energy to the liquid.
3. The ultrasonic transducer converts the input electric energy into mechanical energy. The expression form is that the transducer makes a back-and-forth telescoping motion in the longitudinal direction, and the amplitude is generally several microns.
4. The ultrasonic horn has insufficient amplitude due to the ultrasonic transducer. It needs to be connected to the ultrasonic horn. The amplitude is amplified according to the design requirements, the reaction solution and the ultrasonic transducer are isolated, and it also serves to fix the entire ultrasonic vibration equipment.
5. The ultrasonic tool head is connected to the horn, which transmits the ultrasonic energy vibration to the tool head, and the tool head emits the ultrasonic energy into the chemical reaction liquid.
6. The ultrasonic generator generates high-frequency and high-power current to drive the ultrasonic vibration parts to work. The power of the ultrasonic generator is adjustable to suit different working conditions. A timing controller can also be integrated in the generator as required to set and control the ultrasonic vibration time and interval time.
