Medium mixing type wet grinding dispersing device

Abstract

The present invention provides a medium mixing type wet grinding dispersing device, including a grinding chamber, a medium separator, a flow guide ring, a dispersion impeller and a transmission shaft, the grinding chamber is a closed cylindrical or conical cavity, the upper part of the grinding chamber is provided with a separation cavity, the medium separator is arranged in the separation chamber, the flow guide ring is positioned in the central part of the grinding cavity and is fixedly connected with the transmission shaft, the flow guide ring is driven to rotate by a drive shaft, the outer periphery of the flow guide ring is provided with a plurality of blades; the dispersion impeller is positioned between the bottoms of the flow guide ring and the grinding chamber, the transmission shaft passes through the center of the dispersion impeller, the dispersion impeller comprises at least two parallelly-arranged leaf discs, the leaf discs are provided with a plurality of channels, and every two leaf discs are fixed by a plurality of supporting columns with round or ellipse cross sections, and the medium mixing type wet grinding dispersing device cam disperse a grinding media and a material in high speed, reduces the number of time of circular grinding, and improves the grinding efficiency.

Description

technical field [0001] The invention relates to a medium stirring type grinding and dispersing device, in particular to a medium stirring type wet grinding and dispersing device. Background technique [0002] The medium-stirred wet grinding and dispersing treatment method refers to the process of grinding and dispersing the material and the grinding medium, and the solid particles contained in the material are finely pulverized through the grinding medium to form a dispersion composed of finer particles. Way. At present, this kind of dispersion treatment method has been fully applied in the fields of ink, pigment, coating, ceramics, metal, inorganic substances, battery polar materials, ferrite, carbon powder, graphite powder and cosmetics. [0003] The applicant has previously proposed a utility model patent application for a medium-stirred wet grinding and dispersing device. figure 1 In the schematic cross-sectional structure diagram of the medium stirring type wet grindi...

AI Technical Summary

Problems solved by technology

[0004] In the process of continuous research and development, the applicant found that due to the arrangement of the above-mentioned guide ring, when the material and grinding medium pass through the guide ring, the movement of the material and grinding medium in the grinding chamber will be regularized, which may cause The collision between the material and the grinding medium is not intense enough

In addition, there are also some deficiencies in the arrangement of the above-mentioned dispersing impellers.
