Ultrasonic vibrating rods use ultrasonic waves to have a positive and negative pressure alternating cycle during the transfer process. When the positive phase is pressed, the medium molecules are squeezed to increase the original density of the medium; in the negative phase, the medium molecules are sparse, discrete, and the medium density is reduced.
The ultrasonic vibrating rod can generate ultrasonic waves uniformly around 360 degrees, and the output of the energy is not affected by load changes such as liquid level and temperature difference. Ultrasonic vibrating rods generally include a high-power ultrasonic transducer, a horn, and a tool head for generating ultrasonic vibrations and emitting the vibration energy into the liquid.
Ultrasonic vibrating rods are mainly used for cleaning the inner walls of various types of tubes and tubes. For example, ultrasonic on-line anti-scaling of boilers, ultrasonic cleaning in vacuum/pressure applications, cleaning of inner walls of metal pipes, and fields of high-power sonochemical treatment such as extraction and separation of traditional Chinese medicines, synthesis and Degradation, biodiesel production, treatment of microorganisms, degradation of toxic organic pollutants, biodegradation treatment, biological cell comminution, dispersion and condensation.
Ultrasonic vibrator principle:
The ultrasonic vibrating rod is a physical mechanism that uses ultrasonic waves to pulverize insoluble solids (or liquids) and is generally considered to be an ultrasonic cavitation effect. 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, then suddenly burst and split, and the bubbles after the split will continue to grow and burst. . When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubbles, and due to the high velocity of the liquid around the bubbles, a strong local shock wave is generated in the liquid near the bubbles, and a local high temperature and high pressure are also formed, thereby generating a local high temperature and high pressure. Ultrasonic pulverization and emulsification.
The cavitation of the ultrasonic vibrating rod:
In some cases, the generation of ultrasonic effects is related to the cavitation mechanism, which refers to a series of dynamic processes that occur in the tiny bubbles (holes) present in the liquid under the action of sound waves: oscillation, Expand, shrink, and even collapse. In the event of cavitation, the local state of the liquid changes greatly, resulting in extreme high temperatures and high pressures.
Ultrasonic vibrating rod components:
1 ultrasonic transducer 2 ultrasonic horn 3 ultrasonic tool head 4 ultrasonic drive power. Its manifestation is that the transducer moves back and forth in the longitudinal direction, and the amplitude is generally several micrometers. Such amplitude power density is insufficient and cannot be directly used. The horn is designed to amplify the amplitude, isolate the reaction solution and the transducer, and also serves to fix the entire ultrasonic vibration system. The tool head is connected to the horn, and the horn transmits ultrasonic energy vibration to the tool head, and the ultrasonic energy is emitted from the tool head into the chemical reaction liquid.
