Lithium battery negative electrode smashing and demagnetizing device convenient to clean

Abstract

The invention discloses a lithium battery negative electrode smashing and demagnetizing device convenient to clean. The device comprises a feeding and smashing mechanism, a crushing assembly, a rotating material pushing mechanism, a negative electrode smashing box body and a demagnetizing assembly arranged in the negative electrode smashing box body; the feeding and smashing mechanism is installedon the top of the negative electrode smashing box body, a material guiding hopper is welded to the inner wall of the negative electrode smashing box body and divides the interior of the negative electrode smashing box body into a smashing cavity and a demagnetizing cavity, and the demagnetizing assembly is installed in the portion, in the demagnetizing cavity, of the negative electrode smashing box body; and the feeding and smashing mechanism smashes lithium battery negative electrodes, the crushing assembly crushes the lithium battery negative electrodes, lithium battery negative electrode materials dropping into the demagnetizing cavity are stirred in the rotating material pushing mechanism, fully demagnetized by magnetic rings and magnetic blocks and discharged by a discharge pipe. Smashing, crushing, stirring, demagnetizing and discharging operations of the lithium battery negative electrodes are achieved, the operations are convenient and fast, and the smashing and demagnetizingeffects are good.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing machinery, more specifically, it relates to a lithium battery negative electrode crushing and demagnetization device that is easy to clean. Background technique [0002] In the lithium battery production industry, a large number of lithium battery negative electrode materials need to be ground before production; during the processing of lithium battery negative electrodes, it is necessary to remove iron from the lithium battery negative electrode materials. The circulation method of iron plate iron removal has low iron removal accuracy, and often fails to achieve the required effect of the work; secondly, the mixing chamber and iron removal plate of the device need to be removed before cleaning, which will cause Increase the workload of the staff, and more time-consuming.

[0003] Chinese patent (authorized announcement number: CN207614972U) discloses an easy-to-clean lithium battery negative electrode crushing and demagnetization device. The crushing operation takes a long time. Secondly, the crushed lithium battery negative electrode powder is demagnetized during the falling process of the magnetic block. Due to the short falling time and fast falling speed of the lithium battery negative electrode material, the iron contained in it cannot be completely removed, resulting in Poor demagnetization effect
