Smashing device for graphite lithium battery anode material

Abstract

The invention relates to the technical field of lithium battery anode material smashing equipment, and discloses a smashing device for a graphite lithium battery anode material. The device comprises aworkbench. A smashing cylinder is fixedly connected to the upper surface of the workbench. A fixing hole is formed in the upper surface of the workbench, and a rolling bearing is fixedly connected tothe hole wall of the fixing hole. A rotating mechanism is fixedly connected to the inner wall of the rolling bearing. The upper surface of the smashing cylinder is movably sleeved with a cylinder cover. A fixing rod and a guiding plate are fixedly connected to the inner wall of the cylinder cover. A plurality of sets of symmetrically-distributed smashing blades are fixedly connected to the rod wall of the fixing rod. The side walls of the two ends of the cylinder cover are provided with threaded holes. Fixing bolts are in threaded connection with the hole walls of the threaded holes. The smashing device for the graphite lithium battery anode material has the advantages that the graphite powder collecting efficiency can be improved, the phenomenon that the environment is contaminated by scattered graphite powder, the environment-friendly performance of the device is improved, and the smashing quality of the graphite lithium battery anode material can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of crushing equipment for negative electrode materials of lithium batteries, in particular to a crushing device for negative electrode materials of graphite lithium batteries. Background technique [0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from rechargeable batteries. Lithium-ion batteries are different from lithium-ion polymer batteries because the chemical properties of lithium metal are very active. , making the processing, storage and use of lithium metal very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream negative electrode materials of lithium batteries, and graphite and other materials are usually used. [0003] Existing gra...
