Description
Technical field
The utility model relates to a kind of graphite negative material of lithium ion battery process equipment, specially refers to the abrasive blast equipment of the lithium ion battery negative material of material after graphitization.
Background technology
Graphite negative material of lithium ion battery is the important component part of lithium ion battery.Wherein Delanium structure is more stable, and good cycle is wide in lithium ion battery negative application.
At present, the production process of lithium battery graphite cathode material, is after bulky grain graphite being pulverized by micro-powder crusher, then is carried out nodularization and classification and obtained the powder body material of required particle diameter by balling machine.But raw material utilization rate is lower at present, produces the too small powder of more diameter and can not be used for follow-up production in crushing process, causes the waste of resource.In pulverizing process, after while graphitization from processing front and processing, conventionally there will be caking phenomenon for preventing; so need to be in charging aperture and feed opening Position Design netted filtering structure; with isolation bulk materials; the netted filtering mechanism at charging aperture place can avoid super large piece material to enter grinding machine affects the running of grinding machine; and the netted filtering structure at discharging opening place is used for avoiding not grinding sufficient larger particles or caking enters next step, affect the quality of negative material.Charging device is arranged on taper feed opening and position, discharge nozzle junction filter mostly at present, because the taper feed opening end being connected with discharge nozzle is less, causes blanking velocity slow; Filter and distance suitable for reading are large, are unfavorable for clearing up block material, and production efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can improve the rear particle utilization rate of raw material pulverizing, the abrasive blast equipment of a kind of lithium ion battery negative material that the raw material after pulverizing is sieved.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of abrasive blast equipment of lithium ion battery negative material, comprise grinding machine, it is characterized in that: in grinding machine, be provided with the gear ring for grinding object, in gear ring, be provided with teeth, described grinding machine front end connects taper charging aperture by feed pipe, and grinding machine rear end connects conical discharge port by discharge nozzle, is provided with the screen pack of filtering powder in described discharging opening.
Described screen pack is positioned at 1/2 ~ 1/3 place of conical discharge port.
It is some that described screen pack is provided with mesh, mesh be shaped as square, rectangle and hexagonal any one.
Teeth in described gear ring are any one of hemispherical, the square bodily form and cuboid.
Described charging aperture is provided with the filter screen that filters bulk solid raw material, and the mesh of taper charging aperture filter screen is greater than the mesh of discharging opening screen pack.
Described filter screen is positioned at 1/2 ~ 1/3 place of taper charging aperture.
Workflow of the present utility model is: raw material enters from charging aperture, entering feed pipe by filter screen then enters grinding machine and pulverizes, particle after pulverizing enters conical discharge port by discharge nozzle, what caking or particle diameter were larger can not pass through screen pack, and the less suitable screen pack that passes through of particle diameter out enters subsequent technique from conical discharge port.
The beneficial effects of the utility model are: 1, too small for preventing the pulverized particle of raw material, the teeth of gear ring are changed into the one of hemispherical, the square bodily form or cuboid by triangular pyramidal, can make to reduce the reduction ratio of gear ring to raw material, make the particle diameter after pulverizing can be too not little and waste.
2, for improving blanking velocity, facilitating the cleaning of piece material, enhance productivity, the utility model carries out particular design to feed opening, its feature is that this device is designed to taper, filter is mounted in bell upper position, can increase blanking area, accelerates blanking velocity; Reduce filter and distance suitable for reading, the large block caking materials of easy cleaning, enhances productivity simultaneously.
3, for improving blanking efficiency, this blanking device is designed to pyramidal structure, is beneficial to the downslide of material.And according to the size of inventory, determine the size of broach hopper.
4, for improving blanking velocity, filter design is seen to a mouthful upper position in taper blanking, can increase blanking area, accelerate blanking velocity.
5, for convenience of the cleaning of bulk material, improve cleaning efficiency, filter designs in upper position, can also reduce filter and distance suitable for reading, and the large block caking materials of easy cleaning, enhances productivity.
