Title:
GRAPHITE PULVERIZATION DEVICE FOR NEGATIVE ELECTRODE MATERIAL OF PORTABLE LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2018/119656
Kind Code:
A1
Abstract:
A graphite pulverization device for a negative electrode material of a portable lithium battery. The device comprises a first-stage feeding and pulverization device and a second-stage pulverization a collection device. The first-stage feeding and pulverization device comprises a feed container (1), a first motor (2), a pulverization rotating wheel (4), and a carrier container (14). The carrier container is welded to four wheel supports (15). The feed container (1) is welded to the upper left of the carrier container (14). The pulverization rotating wheel (4) is fixedly arranged on a rotating shaft (5) and within the feed container (1). The first motor (2) is fixedly arranged on a left side of the carrier container (14). The second-stage pulverization and collection device comprises a second-stage pulverization container (10), a feed loading container (13), and a feed collection container (20). The second-stage pulverization container (10) is welded to a left side surface of a right support board (17) and a right side surface of a left support board (23). The feed loading container (13) is fixedly arranged on the right support board (17). The feed collection container (20) is arranged on a lower surface of the carrier container (14) and directly below a feed discharging pipe (21). The device of the present invention employs two-stage pulverization to meet pulverization requirements of a negative electrode material of a lithium battery without adding subsequent process steps, thus saving time and labor, and reducing operational costs.
