Lithium battery material fine-crushing and deironing device

Abstract

The invention provides a lithium battery material fine-crushing and deironing device. The lithium battery material fine-crushing deironing device comprises a fine-crushing screening device and a deironing cleaning device, wherein the fine-crushing screening device comprises a crushing box, a screening box, a feeding box and a charging barrel; the screening box is welded on two support pillars; the crushing box is welded on the screening box; the charging barrel is welded in the center of the upper part of the crushing box; the feeding box is fixedly arranged on the right side of the upper part of a deironing box protection box; the deironing cleaning device comprises a magnetic eraser, a plurality of electromagnetic coils and a water distribution box; the electromagnetic coils are fixedly arranged on two sides of a deironing box; the magnetic eraser is fixedly arranged at the upper part of the left side of the deironing box protection box; the water distribution box is welded at the inner upper part of the deironing box. According to the lithium battery material fine-crushing and deironing device, crushing and deironing are integrated; filtering is performed before crushing to realize accurate crushing; deironing is performed by the deironing device after crushing; meanwhile, cleaning is convenient; time and labor are saved; the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to a lithium battery material processing device, in particular to a lithium battery material fine crushing and iron removal device. Background technique [0002] In the production process of lithium batteries, lithium battery materials need to be pulverized, iron removed, sieved, stirred and mixed to ensure quality so that they can be used for production. Generally, crushing and iron removal are carried out separately. When crushing, after one crushing The particles are not fully up to the standard, they need to be screened and crushed, and now when the iron removal equipment is removing iron, the slurry or dry powder raw materials are input into the inner cylinder from the inlet, and then output from the outlet after passing through the soft magnetic net. The magnetic field magnetizes the soft magnetic net, so that the soft magnetic net has a strong magnetic field. When the dry powder or slurry passes through the soft magnetic ne...

[0002] In the production process of lithium batteries, lithium battery materials need to be pulverized, iron removed, sieved, stirred and mixed to ensure quality so that they can be used for production. Generally, crushing and iron removal are carried out separately. When crushing, after one crushing The particles are not fully up to the standard, they need to be screened and crushed, and now when the iron removal equipment is removing iron, the slurry or dry powder raw materials are input into the inner cylinder from the inlet, and then output from the outlet after passing through the soft magnetic net. The magnetic field magnetizes the soft magnetic net, so that the soft magnetic net has a strong magnetic field. When the dry powder or slurry passes through the soft magnetic net, the ferromagnetic substances in the dry powder or slurry will be adsorbed on the soft magnetic net to remove the ferromagnetic substances in the raw materials. However, when there is too much ferromagnetic slag adsorbed on the soft magnetic net, it is easy to cause blockage. Therefore, the soft magnetic net must be cleaned regularly to remove the ferromagnetic slag on the soft magnetic net before it can be used; during the cleaning process of the soft magnetic net, although the electromagnetic coil The magnetic field of the soft magnetic grid has basically disappeared, but the ferromagnetic slag adsorbed on the soft magnetic grid will still have hysteresis, because the hysteresis of the ferromagnetic slag can also be adsorbed on the soft magnetic grid, which is not easy to clean
