Design and implementation a microcontroller based high power ultrasonic dispersion system with self frequency adjusting property
In This paper a novel ultrasonic dispersion system for the cleaning application or dispersing of particles which are mixed in liquid, has been proposed. The frequency band of designed system is 28 kHz so that the frequency of ultrasonic wave sweeps from 20 kHz to 30 kHz with 100 Hz steps. Transferri...

| Summary: | In This paper a novel ultrasonic dispersion system for the cleaning application or dispersing of particles which are mixed in liquid, has been proposed. The frequency band of designed system is 28 kHz so that the frequency of ultrasonic wave sweeps from 20 kHz to 30 kHz with 100 Hz steps. Transferring a maximum and optimum energy of ultrasonic wave to the liquid conveyor with high efficiency during total usage time is remarkable superiority of designed and manufactured system compares with other similar available systems in markets. High power ultrasonic transducers with the nominal maximum power 110 watt are applied as the ultrasonic wave generator. To increase the efficiency of system and transmitting the maximum energy to the liquid tank, the frequency of system should set on the resonance frequency of transducer. Control section is implemented in system for realtime monitoring and adjusting the frequency of system. Hall Effect current sensor is used as the current sampling component and controlling program is implemented on AVR microcontrollers. The manufactured ultrasonic dispersion system is consisted of 4 high power ultrasonic transducer result in 450 watt ultrasonic energy, effectively. |
