Description
Technical field
The utility model relates to machining graphite apparatus field, specifically a kind of high purity graphite spherical grinding device.
Background technology
The advantage that graphite is used as lithium ion battery negative material is: source is wide, and low price, charging/discharging voltage platform is low, and reversible capacity is high.But the negative material making lithium ion battery with graphite also exists many shortcomings: poor with solvent compatibility, high rate during charging-discharging is bad, the common embedding because of solvent molecule during first charge-discharge makes graphite linings peel off, thus causes reduce electrode life.Conventional solution is to the process of graphite material modifying surface, first native graphite will be pulverized and be processed into qualified spherical graphite powder current graphite granule lapping device by two groups of mutual extruded anisotropic graphite grains of abrasive wheel by various modified graphite, in recent years, there is other manufacturing enterprise for producing spherical graphite powder, the equipment producing common graphite powder is transformed, but its production effect is bad, obtained product does not far reach the index request of spherical graphite powder, the particularly spherical circularity of graphite powder, the particle size distribution of spherical graphite powder, the density index of spherical graphite powder and specific area index etc. cannot realize the technical requirement needed for user, certain degree constrains the application of spherical graphite powder.And there is larger gap in current graphite granule lapping device between abrasive wheel and grinding chamber interior wall, thus make in the splicing case of a part of graphite granule below gap drains to, therefore graphite is caused to grind uneven phenomenon, thus cause regrind or the operation such as to sieve, extend process time, productivity ratio is low.
Utility model content
The purpose of this utility model is the high purity graphite spherical grinding device providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of high purity graphite spherical grinding device, comprise grinding case, grinding chamber and inlet plenum, described grinding case upper end is provided with hopper, installation two groups of abrasive wheels are engaged in grinding case, bending protective plate is fixedly mounted between described abrasive wheel and grinding chamber interior wall, the downside of grinding case is provided with discharge gate, described discharge gate is connected with grinding chamber by pipeline, pipeline between described grinding chamber and grinding case is provided with magnetic valve, described inlet plenum is connected with the lower end of grinding chamber, the upper end, right side of grinding chamber is provided with discharge nozzle, coarse strainer and fie screen is provided with in described discharge nozzle, described fie screen is located at the right side of coarse strainer, be positioned on the downside of the discharge nozzle on the left of coarse strainer and be provided with discharging opening, also discharging opening is provided with on the downside of drainage conduit between coarse strainer and fie screen, the inwall of described grinding chamber is provided with wearing layer.
As further program of the utility model: described discharging storehouse is equipped with magnetic valve.
As the utility model further scheme: the inner surface of described wearing layer is rough and uneven in surface.
Compared with prior art, the beneficial effects of the utility model are: by installing bending protective plate additional between abrasive wheel and grinding case, and graphite granule will, from the slit source between grinding case and abrasive wheel, effectively prevent graphite from grinding uneven phenomenon.After graphite granule enters grinding chamber, time inlet plenum produce at a high speed air-flow graphite granule upwards and upwards roll, graphite granule and grinding chamber produce high velocity impact, graphite granule is made to implement collision in the process, gas current friction, grinding, the actions such as reunion, iterative cycles impacts and makes graphite granule be subject to dual powder simultaneously, within a short period of time, out-of-shape graphite granule was treated to spherical or subsphaeroidal particle, be spherical with the product realizing obtaining, the size distribution of its spherical graphite powder, tap density and specific area, all can be controlled in the scope of prior setting value, also be provided with coarse strainer and fie screen, double filtration, the substandard product filtered down, get rid of from discharging opening, again grind, ensure the qualification rate of particle.
