Description

Micropowder shaping pulverizer

Technical field

The utility model relates to a kind of micropowder shaping pulverizer.

Background technology

Existing lithium ion battery is in the development of communication field with in the rise of electronic new-energy automobile industry, to the increase of the market demand of lithium ion battery, more becomes the focus of research for the research of critical material negative pole in the lithium ion battery.Widely used carbonaceous negative material in the lithium ion battery; Become the material of a large amount of uses, carbonaceous material comprises unformed charcoal, mesocarbon, graphite etc., and use is all arranged in the lithium ion battery field; The microstructure spheroiding of carbonaceous mesophase spherules; And the carbonaceous negative material of other types all will pass through the process of pulverizing ball-typeization in the process of making, and is used for improving the tap density of material, improves the machinability of material in battery processing procedure process; So, mostly fairly simple and shine into micropowder jolt ramming in the processing poorly in the design of mixing component on its structure of existing pulverizer, problem such as the micropowder shaping is inhomogeneous, irregular greatly reduces the battery service efficiency as the primary raw material of battery thus.

The utility model content

The purpose of the utility model is to provide the particle roundness that a kind of pan feeding is even, can effectively improve micropowder, improves the tap density of material, makes material have the excellent physics and the micropowder shaping pulverizer of chemical property.

In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:

A kind of micropowder shaping pulverizer comprises power set, charging aperture, stir chamber, shredder assemblies, support, base and discharging opening, and said mixing component comprises shaft, grating disk, pulverizing module, flow splitter and classifying turbine at least; Said shaft one end connects the power set other end and penetrates in the stir chamber; Grating disk is located on the shaft lower end position in the stir chamber, pulverizes module and is located on the grating disk, and flow splitter is one " funnel " shape; Its bottom is provided with screen cloth; Port is communicated with discharging opening, and flow splitter is fixed on the stir chamber inwall through a location device, and classifying turbine is arranged in the flow splitter.

Further, the crushed face of said pulverizing module is the rhombus inclined-plane.

Further, the rhombus bevel angle of said crushed face is 5 to 30 degree.

Further, said pulverizing module is more than two, equidistant setting between its each pulverizing module.

Further, said pulverizing module is 8 or 16.

In a specific embodiment, also be provided with a feeding serew in the said charging aperture passage.

The beneficial effect of the said micropowder shaping of the utility model pulverizer is: being equipped with of each parts of mixing component makes material in whipping process, receive shake evenly; The crushed face of pulverizing module is provided with certain rake angle makes carbonaceous material be easy to ball-typeization; Thereby improve the tap density of the efficient of nodularization process, the particle roundness that improves material, raising material, make material have excellent physics and chemical property; Feeding mouth is provided with feeding serew makes raw material can get into stir chamber uniformly.
