Smashing device with filtering function for battery cathode material

Abstract

The invention provides a smashing device with a filtering function for a battery cathode material. The smashing device comprises a box body, a filling box, a first smashing device and a second smashing device. The first smashing device is arranged in the box body. A conveying pipe is arranged on the right portion of the box body. The second smashing device is arranged on the top of the box body. The right end of the conveying pipe is connected with a conveying cylinder. A spiral conveying device is mounted in the conveying cylinder. An inclined pipe is connected to the top of the conveying cylinder and connected to the right side of the filling box. The first smashing device is composed of a slave smashing wheel, a first mounting shaft, an active smashing wheel, a smashing motor and a second mounting shaft. The second smashing device is composed of a round cylinder, a first support, a spiral smashing device, a rotating shaft, a second support, a bearing, a belt, a slave wheel, a drive motor, a sealing ring and an active wheel. The smashing device can successively smash the materials twice, so that the smashing fineness and quality are improved; and the materials which are not smashed can be screened out and conveyed to the filling box to be smashed repeatedly.

Description

technical field [0001] The invention relates to a crushing device for negative electrode materials of batteries, in particular to a crushing device for negative electrode materials of batteries capable of filtering. 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 become the mainstream now; lithium battery negative electrode materials usually use graphite and other materials; existing graphite pulverizers include crushing tanks and motors; there are rotating shafts in the tank And the crushing blade, the motor mobilizes the shaft and then drives the crushing blade to crush the graphite raw material; but the crushing effect of such a crusher is not good, the crushing time is long, and it is difficult to process...

Problems solved by technology

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; lithium battery negative electrode materials usually use graphite and other materials; existing graphite pulverizers include crushing tanks and motors; there are rotating shafts in the tank And the crushing blade, the motor mobilizes the shaft and then drives the crushing blade to crush the graphite raw material; but the crushing effect of such a crusher is not good, the crushing time is long, and it is difficult to process the graphite into the required particle size; One-time crushing is often incomplete and cannot meet people's needs; moreover, after crushing, the materials cannot be filtered, and often some of the materials that have not been thoroughly crushed are mixed in the crushed materials, resulting in the overall quality of the crushed materials. Poor, unable to meet people's needs
