Ultrasonic vibrating screen

Abstract

The invention relates to the technical field of waste battery material recovery, and discloses an ultrasonic vibrating screen which comprises a bottom frame, at least two screen drums and a vibrating mechanism. An elastic body is arranged on the bottom frame; the screen drums are sequentially arranged from bottom to top, each screen drum is provided with a screen mesh, and one screen drum is connected with the bottom frame through the elastic body; and the vibrating mechanism comprises a vibrating frame and at least two ultrasonic transducers, the screen drums are all fixed to the vibrating frame, and the ultrasonic transducers are fixed to the vibrating frame and drive the vibrating frame to vibrate. All the screen drums are fixed to the vibrating frame, and original asynchronous amplitudes and frequencies of all ultrasonic transducers are unified into a unified frequency as much as possible.

Description

technical field [0001] The invention relates to the technical field of recycling waste battery materials, in particular to an ultrasonic vibrating screen. Background technique [0002] At present, in the lithium battery recycling process, the crushed battery powder becomes black battery powder after being dried and pyrolyzed. These battery powders become battery powder after being crushed. In order to obtain these granular powders, it is necessary to sieve through a sieve, and a vibrating mesh sieve is required in the sieve sieving process. [0003] The multi-layer ultrasonic screen currently used is equipped with multiple ultrasonic transducers on each layer of the screen. When working, these ultrasonic transducers vibrate at high speed together to drive the vibration of the screen to screen the battery powder. Efficient recycling of battery points, but in the process of use, the life of the ultrasonic screen is very short, and the screen often breaks along a straight line...

[0003] The multi-layer ultrasonic screen currently used is equipped with multiple ultrasonic transducers on each layer of the screen. When working, these ultrasonic transducers vibrate at high speed together to drive the vibration of the screen to screen the battery powder. Efficient recycling of battery points, but in the process of use, the life of the ultrasonic screen is very short, and the screen often breaks along a straight line after a period of use, and the life of the new screen will not exceed three months , sometimes the shortest life of the screen is not even more than one month. Although there are many modifications and reinforcements to the screen in the prior art, none of them can solve the problem of screen breakage, so the screen needs to be replaced frequently during use. , not only wastes the screen material, but also takes time and effort to replace the screen, and the production line needs to be stopped during the replacement. Such frequent maintenance causes a large loss of production capacity
