Abstract

The invention provides a graphite shaping machine which comprises a stator gear ring, a rotor set, a flow chocking ring, a feeding hole, flowing gaps, flow chocking ring grinding area gaps, stator gear ring grinding area gaps, a main shaft, a shell, a belt wheel, a shaft sleeve and the like, wherein a material is fed into the shaping machine through the feeding hole and is fed into the stator gear ring grinding area gaps for crushing, grinding and balling; when the material is fed into a next grinding area, auxiliary blades on an opposite side of the rotor set rotate at a high speed to generate annular eddy in the flow chocking ring grinding area gaps, large-granule materials are retained and further crushed and balled, and qualified small granules are fed into the next grinding area for grinding through the flowing gaps. By adopting the graphite shaping machine, the balling function on the material is enhanced, meanwhile an automatic classification process for large and small granular materials is achieved, a graphite material is made into a qualified product within a shortest process, the production rate of a finished product is improved, the number of process systems is reduced, and the energy consumption of the product is reduced.

Description

A kind of graphite trimmer

Technical field

The present invention relates to the pulverizing shaping device of graphite material, relate in particular to a kind of graphite trimmer.

Background technology

Graphite material is with its good electroconductibility, good charging/discharging voltage platform, higher specific storage and source widely, and dominate always in lithium ion battery negative material becomes the study hotspot of negative material.Lithium cell is mainly divided into natural graphite and synthetic graphite with graphite material.Natural graphite is taking crystalline flake graphite as main, and synthetic graphite comprises needle coke, refinery coke, carbon nanotube and carbonaceous mesophase spherules etc.Two kinds of graphite is because of the impact of formation condition and complete processing, and material structure is different, causes material property also to have larger difference.Compared with synthetic graphite, natural graphite specific storage is large, technique is simple, price is relatively low, but poor stability, high rate performance are not good, electrolytic solution bad adaptability.In order to improve cyclical stability and the tap density of graphite, industrial natural graphite is done to globulate or subsphaeroidal, but because being subject to its preparation technology's restriction, cause that product yield is low, energy consumption is large, cost is high, and the sphericity that makes spherical graphite is not high, and the performance of product is undesirable.Because hardness is larger, easily there is volume and pulverize in synthetic graphite (except carbonaceous mesophase spherules), existing installation and technique are difficult to do globulate in spheroidization process.At present, domestic graphite spheroidization equipment is mainly eddy current mill, there is no professional shaping device, shaping mechanism mostly is impact shaping, graphite granule will be smashed if surging force is excessive, cause productive rate to reduce, and not good for larger this equipment shaping effect of synthetic graphite of hardness, can only play porphyrization.Although there is other equipment that graphite is carried out to shaping abroad, expensive, still not good to the shaping effect of electrographite.

Summary of the invention

The object of the invention is to overcome prior art deficiency, a kind of graphite trimmer is provided.

A kind of graphite trimmer, comprises stator ring, rotor assembly, choking ring, opening for feed, circulation gap, gap, choking ring milling zone, gap, stator ring milling zone, main shaft, casing, belt wheel, axle sleeve, abrading block, rotor disk, auxiliary blade, wedge shape circle-arc tooth, wedge shape arc groove, cylindrical grinding block, square abrasive block;

Belt wheel is arranged on main shaft, and main shaft is arranged on casing; Axle sleeve is connected with rotor disk, and axle sleeve and main shaft adopt spline joint, and abrading block is arranged on rotor disk, circumference uniform distribution 10-20 piece on rotor disk, wherein disintegrating area square abrasive block, shaping region cylindrical grinding block; By hardness and the big or small number of determining the milling zone that square abrasive block is installed of material, each rotor back side circumference radial equipartition is equipped with auxiliary blade, length 100mm-200mm, height 10mm-30mm;

Stator ring and choking ring have identical external diameter, and stator ring is equidistantly arranged on internal side of shell, and choking ring embeds between two stator rings, and stator ring inner side is processed with dozens of wedge shape circle-arc tooth, and choking ring one side is processed with radial wedge shape arc groove;

Rotor assembly is installed between choking ring, forms gap, choking ring milling zone between the wedge shape arc groove on auxiliary blade and choking ring, gap size 2mm-10mm, forms gap, stator ring milling zone, gap size 3mm-10mm between abrading block and stator ring;

Choking ring inner ring diameter is greater than main shaft diameter, forms circulation gap; Rotor assembly, choking ring, stator ring form one group of milling zone, organize milling zone more and distribute along main shaft.

The present invention has following beneficial effect: material enters trimmer by opening for feed, enter in gap, stator ring milling zone and pulverized, grind and nodularization, in the time entering next group milling zone, the auxiliary blade high speed rotating of rotor assembly reverse side, produce vortex ring in gap, choking ring milling zone, by large granular materials detention, further pulverize nodularization, qualified small-particle enters next group milling zone by circulation gap and grinds, strengthen the nodularization function to material, form the automatic classification process of a large or fine granule material simultaneously, make graphite material in the shortest flow process, become qualified product, increase finished product productivity, shorten the quantity of process system, reduce product energy consumption.
