Ultrasound rotary vibro sifter system is a simple, practical and reliable screening system. It is the most effective solution to mesh blockage at present. On the basis of DH series rotary vibration screens produced by Dahan Machinery in recent 30 years, a high-frequency and low-amplitude ultrasonic vibration wave is superimposed on the screen.
Ultra-fine powder accepts huge amounts. Ultrasound acceleration keeps the material on the screen in suspension state all the time, thus restraining the blocking factors such as adhesion, friction, leveling and wedging, thus solving the screening problems such as strong adsorption, easy reunion, high static electricity, high precision, high density and light specific gravity, making the screening of ultrafine powder no longer difficult, especially suitable for high-quality products. Users of high quality and fine powder.
Of course, the maintenance of ultrasonic sifter is very important. So what are the factors that affect the cleaning of the screen of the ultrasonic rotary vibro sifter?
Let's analyze:
First, the lower the viscosity of the cleaning solution, the higher the gas content, the better the cleaning effect.
Secondly, the location of the cleaning material and the depth of the cleaning liquid are also one of the factors. If the location of the cleaned object is concealed, it will be difficult to clean.
Third, the lower the frequency, the more obvious the cavitation effect, but the noise is relatively high, which is suitable for objects with relatively flat surface. The higher the frequency is, the worse the cavitation effect is, but the noise is relatively low. It is suitable for objects with more blind hole effect and electronic crystals.
Fourth, in general, the cleaning effect is the best at the medium temperature of 30 - 50 C. Out of this range, the cleaning effect will not be ideal.
Fifth, the screening effect of ultrasonic rotary vibro sifter is related to the sound intensity, so according to the different frequencies, the sound intensity is generally selected at about 1-2w/cm2.
