Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic vibration screens, in particular to an ultrasonic vibration screen for removing black powder on a positive aluminum sheet of a lithium battery. Background Art

[0002] Ultrasonic vibrating screen converts 220v, 50HZ or 110v, 60HZ electric energy into 38KHZ high-frequency electric energy, inputs it into ultrasonic transducer, and converts it into 38KHZ mechanical vibration, so as to achieve the purpose of efficient screening and net cleaning. Based on the traditional vibrating screen, this system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen, and superimposes a high-frequency, low-amplitude ultrasonic vibrator on the screen. The ultra-fine powder receives huge ultrasonic acceleration, so that the material on the screen surface always remains in a suspended state, thereby inhibiting adhesion, friction, flat drop, and other factors that block the screen. It solves the screening problems of strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity, making ultra-fine powder screening no longer difficult, and is particularly suitable for users of high-quality and fine powders.

[0003] The existing ultrasonic vibration screen for removing black powder from positive aluminum sheets has the following problems: 1. During the input and transportation of positive aluminum sheets, blockage may occur due to excessive accumulation in a certain place. At the same time, excessive accumulation in a certain place may cause a large amount of black powder to fail to fall off completely; 2. It is impossible to completely remove the black powder only by using a vibration screen, which will affect the processing accuracy and cause some positive aluminum sheets to require a second black powder removal.
