Solid-liquid dual-purpose electrode material demagnetizing and crushing device

Abstract

The invention provides a solid-liquid dual-purpose electrode material demagnetizing and crushing device. The solid-liquid dual-purpose electrode material demagnetizing and crushing device comprises abox. The box comprises a solid demagnetizing cavity, a middle partition plate and a liquid demagnetizing cavity. A graphite feed hopper, a crushing device, a demagnetizing device and a box door are arranged in the solid demagnetizing cavity. The crushing device comprises a driving motor and a rotary shaft. The first demagnetizing device comprises a first demagnetizing plate, a second demagnetizingplate, a third demagnetizing plate, a fourth demagnetizing plate and a fifth demagnetizing plate. The box door is arranged at the lower left end of the solid demagnetizing cavity, and a handle is arranged on the box door. The middle partition plate is arranged between the solid demagnetizing cavity and the liquid demagnetizing cavity. An oblique base plate, a discharging pipe, a second demagnetizing device, a guide plate and a liquid inlet hopper are arranged in the liquid demagnetizing cavity. The second demagnetizing device comprises cylinders and guide bars. Magnet bars are arranged in thecylinders in a sleeved mode. The liquid inlet hopper is arranged at the upper end of the liquid demagnetizing cavity. The solid-liquid dual-purpose electrode material demagnetizing and crushing device can achieve cyclic demagnetization, and thus, demagnetization is complete; and meanwhile, solid-liquid demagnetization can be achieved, and thus, the efficiency is high.

[0003] In the production process of lithium batteries, some raw materials contain a lot of magnetic foreign matter. The existence of magnetic foreign matter has brought great hidden dangers to the safety performance of lithium batteries. The key to the problem; currently graphite materials and some electrode material slurries contain magnetic foreign matter, most of the devices do not have demagnetization function or have a certain demagnetization function, but the demagnetization is not complete; it cannot demagnetize solids and liquids at the same time, and the efficiency low
