A graphite lithium battery negative electrode material crushing and collecting device

Abstract

The invention provides a crushing and collecting device for graphite for manufacturing negative electrode materials for lithium ion batteries. The crushing and collecting device comprises a primary feeding and crushing device and a secondary crushing and collecting device; the primary feeding and crushing device comprises a first motor, a primary crushing box and a feeding box, wherein the first motor is fixedly arranged on a left carrying plate, the feeding box is fixedly arranged at the central position of a base, the left side surface of the primary crushing box is welded on the right side surface of the left carrying plate, and the right side surface of the primary crushing box is welded on the left side surface of a second connecting plate; and the secondary crushing and collecting device comprises a collecting box, a secondary crushing box and a hydraulic cylinder, wherein the secondary crushing box is welded on the left side surface of a right carrying plate and the right side surface of a first connecting plate, the hydraulic cylinder is fixedly arranged on a fixing plate, and the collecting box is arranged on the base and below the secondary crushing box. The crushing and collecting device for the graphite for manufacturing negative electrode materials for lithium ion batteries has the advantages that the graphite is crushed through the two-stage crushing device so that the crushing effect and efficiency of the graphite can be improved, and meanwhile, the crushing quality of the graphite can be ensured.

Description

Technical field [0001] The invention relates to a processing device for battery negative electrode material, in particular to a crushing and collecting device for graphite lithium battery negative electrode material. Background technique [0002] Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements; therefore, lithium batteries have not been used for a long time; with the development of science and technology, lithium batteries have now become the mainstream; lithium The battery negative electrode material usually uses graphite and other materials; the existing graphite grinder includes a crushing tank and a motor; the tank is equipped with a rotating shaft and a crushing blade, and the rotating shaft is adjusted by the motor to drive the crushing blade to crush the graphite raw materials; but the crushing effect of such a crusher is not Well, the pulverization time is long, and it ...

Problems solved by technology

[0002] Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements; therefore, lithium batteries have not been used for a long time; with the development of science and technology, lithium batteries have become the mainstream now; Materials such as graphite are usually used as the negative electrode material of the battery; the existing graphite pulverizer includes a pulverizing tank and a motor; the tank body is provided with a rotating shaft and a pulverizing blade, and the motor mobilizes the rotating shaft to drive the pulverizing blade to pulverize the graphite raw material; but the pulverizing effect of such pulverizing machine is not good. Well, the crushing time is long, and it is difficult to process graphite into the required particle size
