Special high-efficiency stirrer for conductive slurry

Abstract

A special high-efficiency stirrer for conductive slurry is characterized in that a first motor is arranged in the center of the top of a stirrer shell, and a second motor is arranged in the center of the bottom of the stirrer shell; and a first motor shaft, a transverse stirring rod, tilting stirring rods, a vertical stirring rod, a second motor shaft and a bottom rotating disc are arranged in the stirrer shell. The design of multiple stirring rods is adopted to improve the multi-angle stirring efficiency, various blades are cooperated to effectively scatter large agglomerates in the slurry from all angles, and the bottom rotating disc is especially arranged to effectively prevent the deposition phenomenon in the stirrer body, so the use efficiency is improved.

Description

Technical field [0001] The invention relates to a high-efficiency mixer special for conductive paste. Background technique [0002] As an important part of battery production, conductive paste needs to mix a variety of raw materials during its preparation. During the mixing process, the semi-finished paste is prone to have large agglomerates, and the large agglomerates need to be broken up in time. Stir the material uniformly, otherwise it will easily lead to a series of performance degradations such as conductivity and field emission performance. Most of the currently used stirring equipment uses purchased reactors or dispersers for stirring. Common reactors or dispersers mostly use a single or multiple vertical stirring rod structure, and the stirring rod rotates inside the machine for stirring. Although it can achieve a certain stirring effect and mix the liquid slurry, it cannot break up large agglomerates in a targeted manner. The stirring effect is often poor and it is dif...

Problems solved by technology

[0002] As an important part of battery production, conductive paste needs to be mixed with various raw materials. During the mixing process, semi-finished paste tends to have large aggregates. It is necessary to break up the large aggregates in time and separate the paste. Stir the material evenly, otherwise it will easily lead to a series of performance reductions such as electrical conductivity and field emission performance

Most of the mixing equipment currently used is stirred by outsourced reactors or dispersing machines. Most of the common reactors or dispersing machines use a single or multiple vertical stirring rod structure, and the stirring rods are rotated inside the machine for stirring. Although it can achieve a certain stirring effect and mix the liquid slurry, it cannot break up the large aggregates in a targeted manner, and the stirring effect is often poor, and it is difficult to meet the quality requirements of the conductive paste.

[0003] And during the stirring process of the conductive paste, the technicians found that it is difficult to touch the paste at the bottom of the body due to the ordinary stirring rod stirring inside the body, so the bottom of the body is prone to aggregate deposition, which is not conducive to the uniform stirring of the conductive paste
