Background

The ultrasonic vibration sieve is a machine which converts electric energy into mechanical energy so as to realize efficient sieving of materials. When the ultrasonic vibration screen is used, an eccentric weight arranged on an output shaft of the vibration motor generates ultrasonic vibration waves, and after the ultrasonic vibration waves are transmitted to the screen, superfine powder on the screen receives huge ultrasonic acceleration, so that the screen blocking factors such as adhesion, friction, flattening, wedging and the like are inhibited, the screening efficiency and the screen cleaning efficiency are improved, and the ultrasonic vibration screen is particularly suitable for screening materials with high quality and fine powder (such as lithium ion battery anode materials). The motion track of the material on the screen can be changed by adjusting the phase angle of the eccentric heavy hammer, so that the screening or filtering of the materials with different specific gravities is satisfied.

The main process of screening materials by utilizing the ultrasonic vibration screen is as follows: placing the material on a screen, starting a vibration motor to enable an eccentric heavy hammer to generate ultrasonic vibration waves, collecting material particles smaller than the screen mesh after passing through the screen under the action of the ultrasonic vibration waves, and enabling the material particles larger than the screen mesh (namely screen fabric) to remain on the screen. Along with the continuous material screening, the material particles larger than the mesh number of the screen are continuously accumulated on the screen, so that the normal screening efficiency is affected, and the material particles remained on the screen need to be cleaned after a period of use.
