Description

Technical Field

[0001] The utility model relates to the technical field of grinding and crushing, and more specifically to a graphite raw material crushing device for graphite purification. Background Art

[0002] Graphite, as a non-metallic mineral, has a layered structure. The layers are combined by weak van der Waals forces, making it easy for graphite to slide or peel along the layers when subjected to external forces. However, the original graphite raw materials often exist in large chunks or granular forms, with uneven particle size distribution and may contain impurities, which are not conducive to subsequent purification processes. In order to improve the efficiency and quality of graphite purification, it is first necessary to perform crushing treatment on the original graphite raw materials. The role of the crushing device is to break large graphite raw materials into smaller particles or powders, making their particle size distribution more uniform and facilitating subsequent physical or chemical purification processes. At the same time, the crushing process can also remove some impurities to a certain extent and improve the purity of graphite.

[0003] Deficiencies of the prior art: In graphite raw materials with insufficiently fine crushing, larger particles often enclose more impurities, which are difficult to completely remove during subsequent purification processes, thus affecting the purity of the final product. Larger particle-sized graphite raw materials require longer reaction times and higher energy consumption during the purification process to ensure that the impurities can fully react and be removed, which increases the difficulty and cost of the purification process. The huge crushing device will occupy a large amount of production space, resulting in a decrease in the space utilization rate of the workshop or factory, which is not conducive to the optimization of the production layout. Large crushing devices are usually expensive, increasing the initial investment cost of the enterprise. Large crushing devices are often suitable for large-scale production and may be difficult to adapt to small-batch, multi-variety production requirements, reducing the flexibility of production. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a graphite raw material crushing device for graphite purification to solve the problems existing in the above-mentioned background art.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. By providing a grinding cone for secondary fine grinding, through two-stage grinding, it is beneficial for the particle size distribution of the graphite raw material to be more uniform, reducing the proportion of over-sized or over-fine particles, which is conducive to the smooth progress of subsequent processing and purification processes.

A fixing bolt 202 is threadedly connected to the side surface of the feeding funnel 201. Side wall triangular tooth blocks 203 are threadedly connected to the inner side wall of the crusher 2. The fixing bolt 202 is provided on the side surface of the feeding funnel 201 to ensure the stable connection between the feeding funnel 201 and the crusher 2.

[0025] According to a graphite raw material crushing device for graphite purification as claimed in the claim, a first high-power motor 301 is fixedly connected to the side surface of the stabilizing frame 3. A first gear 302 is fixedly connected to the bottom end of the first high-power motor 301. A second high-power motor 303 is fixedly connected to the top end of the stabilizing frame 3.

[0026] Among them, a first steel shaft 308 is fixedly connected to the side surface of the second high-power motor 303. A second gear 304 is fixedly connected to the outer circle of the first steel shaft 308. A positive-thread crushing block 306 is fixedly connected to the outer side wall of the first steel shaft 308. A movable fixing collar 309 is movably connected to the side surface of the first steel shaft 308.

[0027] Among them, a third gear 305 is in gear engagement with the side surface of the second gear 304. A second steel shaft 310 is fixedly connected to the inner side wall of the third gear 305. A reverse-thread crushing block 307 is fixedly connected to the outer side wall of the second steel shaft 310.

[0028] Working principle of the present utility model: The graphite raw material first enters the crusher 2 through the feeding funnel 201. The side of the feeding funnel 201 is provided with fixing bolts 202 to ensure the stable connection between the feeding funnel 201 and the crusher 2. The inside of the crusher 2 is equipped with sidewall triangular tooth blocks 203, which are connected to the inner sidewall of the crusher 2 by threads and are used for initially crushing the incoming graphite raw material. When the graphite raw material enters the crusher 2, it is initially crushed into smaller particles under the extrusion and shearing action of the sidewall triangular tooth blocks 203. The initially crushed graphite particles enter the grinding cone 1 through the receiving tipping bucket 102. The outer sidewall of the grinding cone 1 is fixedly connected with an external gear 101, which is used to connect with a driving device such as a motor and a gear set to achieve rotational motion. A conical grinding device 103 is placed inside the grinding cone 1, and a threaded grinding tooth 104 is fixed on its outer sidewall. When the grinding cone 1 rotates, the conical grinding device 103 generates relative motion with the inner wall of the grinding cone 1 through the threaded grinding tooth 104 to grind and refine the graphite particles. The top of the conical grinding device 103 is provided with an anti-accumulation cone 105 to prevent the graphite particles from accumulating on the top of the conical grinding device 103 during the grinding process and ensure the continuity and uniformity of the grinding process. For the first grinding, after the graphite raw material is initially crushed in the crusher 2, it enters the grinding cone 1 for the first grinding. At this time, the relative motion between the grinding cone 1 and the conical grinding device 103 initially refines the graphite particles. The graphite particles after the first grinding continue to be ground in the grinding cone 1, especially through the fine grinding of the threaded grinding tooth 104, to further refine the particles and make the particle size distribution more uniform.

[0029] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
