Lithium battery negative pole material stirring and mixing apparatus

Abstract

The invention provides a lithium battery negative pole material stirring and mixing apparatus. The lithium battery negative pole material stirring and mixing apparatus comprises a tank body, an upper cover, a material guide device, a first mixing device and a second mixing device, wherein a first mixing cavity is arranged in the tank body, and the upper cover is arranged at the opening on the top; a material guide tray, the material guide device and the first mixing device are arranged in the first mixing cavity; the material guide device is composed of a first motor, a material guide rotation shaft and a material guide plate; the first mixing device is composed of a second motor, a first mixing rotation shaft, a stirring blade and a stirring frame; two communicating pipes are symmetrically arranged on the bottom surface of the tank body; each communicating pipe is provided with a baffle plate, and the other end of the communicating pipe communicates with the second mixing device; and the second mixing device is composed of a material mixing pipe, a third motor, a second mixing rotation shaft, a first spiral material mixing plate and a second spiral material mixing plate. By arranging the two mixing devices, raw materials can be sufficiently mixed, thereby being beneficial to improving the mixing speed.

Description

technical field [0001] The invention relates to an electrode material mixing device, in particular to a lithium battery negative electrode material stirring and mixing device. Background technique [0002] Lithium battery anode materials need to be mixed with various powder materials. At present, when mixing two or more materials, in order to improve the stirring effect and make the materials more uniform, it is often necessary to use stirring equipment for mixing. The work of the currently used mixing equipment mainly relies on the stirring blades in the mixing equipment to provide a single driving force for the materials, so as to achieve the purpose of mixing the materials. However, this single driving mode has limited mixing capacity and low material mixing efficiency. Low, uneven mixing, and slow mixing speed, resulting in more time and energy consumption for material mixing operations, which greatly limits the improvement of material processing production efficiency an...
