Dual-purpose magnetism-removal smashing device for solid-liquid electrode material

Abstract

The invention provides a dual-purpose magnetism-removal smashing device for a solid-liquid electrode material. The dual-purpose magnetism-removal smashing device comprises a box body, wherein the box body comprises a solid magnetism-removal cavity, an intermediate partition board and a liquid magnetism-removal cavity; the solid magnetism-removal cavity is internally provided with a graphite feed hopper, a smashing device, magnetism removing devices and a box door; the smashing device comprises a drive motor and a rotating shaft; a first magnetism removing device comprises a first magnetism removing plate, a second magnetism removing plate, a third magnetism removing plate, a fourth magnetism removing plate and a fifth magnetism removing plate; the box door is arranged at the left lower end of the solid magnetism-removal cavity, and a handle is arranged on the box door; the intermediate partition board is arranged between the solid magnetism-removal cavity and the liquid magnetism-removal activity; the liquid magnetism-removal activity is internally provided with an inclined base plate, a discharge tube, a second magnetism removing device, a flow guide plate and a liquid feed hopper; the second magnetism removing device comprises a cylinder and a flow guide rod; a magnet rod is arranged in the cylinder in a sleeving manner; and the liquid feed hopper is arranged at the upper end of the liquid magnetism-removal cavity. According to the device, the magnetism is removed in a circulating manner, and the magnetism removal is thorough; and solid magnetism removal and liquid magnetism removal can be carried out simultaneously, so that the efficiency is high.

Description

technical field [0001] The invention relates to an electrode material demagnetization machine, in particular to a dual-purpose demagnetization and crushing device for solid and liquid electrode materials. Background technique [0002] 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. Contents of the invention [0003] The object of the present invention is to provide a dual-purpose demagnetization and crushing device for solid-liquid electrode materials...
