Pelletizing and screening integrated device for lithium ion battery cathode material

Abstract

The invention relates to a pelletizing and screening integrated device for a lithium ion battery cathode material. The pelletizing and screening integrated device for the lithium ion battery cathode material comprises a charging box, a circulating lifting apparatus, a smashing barrel apparatus, a material conveying barrel, an inclined screen and a swinging screening apparatus. The swinging screening apparatus is welded to the upper ends of four supports; the inclined screen is welded to the inner wall of a first screening box; the left end of the inclined screen is lower than the right end ofthe inclined screen in position; the left end of the material conveying barrel is welded to the left side wall of a smashing outer barrel, and the right end of the material conveying barrel is disposed in a second bearing; the lower end of the charging box passes through the left side wall of the upper end of the smashing outer barrel to be fixedly disposed in the material conveying barrel, and the upper end of the charging box is disposed at the upper end of the smashing outer barrel; the circulating lifting apparatus is fixedly disposed at the upper end of a spring restoration box; and the smashing barrel apparatus is fixedly disposed among eight rotating rolling wheels. The pelletizing and screening integrated device for the lithium ion battery cathode material is reasonable in design,convenient to use and capable of performing circulating smashing and multi-level screening, the graphite particles are uniformly sized, and the smashing speed is improved.

Description

technical field [0001] The invention relates to a lithium ion battery negative electrode material processing equipment, in particular to a lithium ion battery negative electrode material granulation and screening integrated device. Background technique [0002] Lithium battery (Lithium battery) refers to the battery containing lithium in the electrochemical system. Lithium battery can be roughly divided into two categories: lithium metal battery and lithium ion battery; the negative electrode material of lithium battery is mainly graphite. When producing lithium battery negative electrode, Graphite needs to be crushed, screened, mixed, etc., and crushing is a relatively important process, which requires uniform particle size and high crushing efficiency; however, the size range of the particles crushed by the existing crushing device is relatively large. In the later screening process, many particles do not meet the production requirements and need to be reprocessed, and the...
