Working principle of ultrasonic vibrating screen
The working principle of ultrasonic vibrating screen combines ultrasonic technology and mechanical vibration.
1. The ultrasonic generator converts 220 volts 50 Hz or 110 volts 60 Hz electrical energy into high frequency electrical energy of 36 kHz to 40 kHz.
2. These high-frequency electrical energy are input into the ultrasonic transducer and converted into mechanical vibration.
3. This mechanical vibration is used to generate high-frequency vibration on the screen, which allows the materials on the screen to be excited by ultrasonic waves while undergoing low-frequency oscillating motion.
4. Due to the high-frequency vibration and compression effect of ultrasonic waves, materials can more easily pass through the screen holes. At the same time, the vibration force promotes the vibration and impact of materials on the screen surface to achieve an efficient screening process.
5. The ultrasonic vibrating screen can also effectively remove clogging problems on the screen, such as adhesion, agglomeration and static electricity, thereby maintaining the continuity and efficiency of screening.
In summary, the ultrasonic vibrating screen converts electrical energy into mechanical vibration and superimposes this vibration on the screen, combined with the characteristics of ultrasonic waves, to achieve efficient and accurate material screening, and can reduce clogging and improve screening efficiency. efficiency and quality.
What are the advantages of ultrasonic vibrating screen?
1. The ultrasonic screen cleaning device can effectively solve the problem of screen blocking of fine materials, with an accuracy of over 95%, and the output is 1-10 times that of ordinary vibrating screens;
2. Energy-saving and environmentally friendly, the whole machine adopts a fully sealed design, which can effectively prevent the escape of powder materials and ensure a clean and hygienic production environment. The entire equipment consumes less energy;
3. Simple operation. With the automatic loading and receiving system, no manual operation can be realized, and the operation can be contacted 24 hours a day;
4. Long service life and easy maintenance, the screen can be replaced in 3-5 minutes;
5. Low noise, small size, and the installation of universal wheels allows for random placement of production.
What are the disadvantages of ultrasonic vibrating screens?
1. Compared with ordinary vibrating screens, the price of ultrasonic vibrating screens will be 30%-50% higher;
2. Adopting a glued mesh frame structure requires professional mesh gluing tools for gluing;
3. Not suitable for screening large granular materials;
