Reaction device for dispersing and blending battery materials

Abstract

The invention provides a reaction device for dispersing and blending battery materials. The reaction device comprises a barrel and a reaction box, wherein the barrel is provided with a feeding barrel, a support rod, a motor plate, a first motor, a rotating shaft, a T-shaped stirring rod, a crossed guide tube, a material receiving curved plate, a spiral stirring blade, a second motor and an annular opening; the feeding barrel is vertically arranged at the middle position of the upper end face of the barrel; the reaction box is provided with a water inlet, a movable plate, a push rod, a seal ring, a valve, an electric heating plate, a partition plate, a pulling frame and a box door; and the reaction box is arranged at the lower end of the barrel and communicates with the barrel. The T-shaped stirring rod of the reaction device is used for stirring the materials in the feeding barrel along with the rotation of the rotating shaft, so that the materials are mixed together; the bottom surface of the feeding barrel is a downward convex spherical surface, so that the materials are convenient to collect and outflow from the middle of the bottom surface; and the crossed guide tube is convenient for enabling the materials mixed together to outflow from multiple ports, and a small quantity of the battery materials is convenient to outflow uniformly, so that blending is facilitated.

Description

technical field [0001] The invention relates to battery material processing equipment, in particular to a reaction device for dispersing and mixing battery materials. Background technique [0002] Reaction equipment is widely used in production users such as petroleum, chemical industry, rubber, pesticide, dyestuff, medicine, food and various scientific research and experimental projects. In recent years, the liquid-phase synthesis reaction kettle has been used in the production of battery materials, and has very broad development potential and application prospects. The reactor for positive and negative materials of lithium battery is basically a traditional normal pressure reactor. General battery materials The traditional atmospheric kettle is only composed of the kettle body, the stirring paddle in the kettle body and the thermometer on the kettle body. Only the stirring paddle is used to stir the materials, and it is impossible to achieve high-speed dispersion and shea...

AI Technical Summary

Problems solved by technology

General battery materials The traditional atmospheric kettle is only composed of the kettle body, the stirring paddle in the kettle body and the thermometer on the kettle body. Only the stirring paddle is used to stir the material, and it is impossible to achieve high-speed dispersion and shearing of the precursor.

Therefore, it is difficult to stir the materials at various points in the reactor evenly, resulting in low purity of the produced product powder, poor crystallinity, inconsistent particle size distribution, and difficult control of batch uniformity, resulting in poor quality of the finished battery
