Description

A kind of lithium battery superfine powder disintegrating apparatus
Technical field
This utility model relates to the production apparatus field of lithium battery, particularly to the disintegrating apparatus of cathode of lithium battery superfine powder.
Background technology
Along with field of lithium battery application constantly expands, lithium battery being required, performance requirement improves constantly, particularly the requirement of high rate performance and high temperature performance aspect performance significantly improves a lot, and the performance of lithium battery material is just had higher requirement by this. And lithium cell cathode material size is lithium battery high rate performance and the key factor of temperature characterisitic impact, it is therefore desirable to process the negative material of little particle diameter. The equipment producing superfine powdery material at present is mainly disc air flow type disintegrating machine and spiral jet pulverizer, due to the pulverizing chamber simple in construction of flat air flow crusher, it is easy to manufacturing, therefore it is widely used. It is mainly made up of pulverizing chamber, jet hole, discharging opening, air stream outlet, compressed air inlet, graded region etc., its operation principle: compression air is become high velocity air by nozzle, be subject to the shear action of high velocity air when material sends into pulverizing chamber by feeder, strong impact makes crushing material become superfine product with violent friction. Owing to gas drives material high-speed to rotate, thus producing great centrifugal force, granule is brought in crushing chamber under the influence of centrifugal force and repeatedly pulverizes, and fine powder is discharged from center discharging opening. This table roller jet mill, although the material particle in pulverizing chamber produces ultrahigh speed eddy flow and has very big kinetic energy, but owing to the direction of Particles Moving is generally consistent, so the shock degree produced between particle is very restricted, particle pulverize the friction mainly relied between particle, this results in huge kinetic energy that Motion Particles possesses, and quite a few is lost. Therefore the disadvantage of disc air flow type disintegrating machine is that the energy consumption of product is big, efficiency is low.
Utility model content
The applicant, for the disadvantages mentioned above of prior art, carries out studying and improving, it is provided that a kind of lithium battery superfine powder disintegrating apparatus, energy consumption is low, efficiency is high feature that it has.
In order to solve the problems referred to above, this utility model adopts following scheme:
A kind of lithium battery superfine powder disintegrating apparatus, including crushing bin, crushing bin is connected with air inlet pipe, with feed nozzle and discharging opening on crushing bin, the cross section of described crushing bin is ellipsoidal structure, and described feed nozzle is positioned at the short shaft end side of crushing bin, and discharging opening is positioned at the center, upper surface of crushing bin, the inwall being positioned at the crushing bin of feed nozzle offside is provided with curved baffle, forms the circular cyclone of two reverse rotations during feed nozzle high speed charging after impacting described curved baffle; Described air inlet pipe includes air inlet supervisor and many and the air inlet air intake branches that are connected of supervisor, air intake branch interval be arranged in crushing bin outer wall and with the inner space of crushing bin, the air inlet of air intake branch is arranged along the tangential direction of described circular cyclone.
Of the present utility model have the technical effect that
This utility model is by becoming oval plate by circular tray designs, the oval plate jet mill of design just makes up the deficiency of table roller jet mill, it can reasonably control the direction of motion of air-flow particle, take full advantage of the huge kinetic energy that particle has when ultrahigh speed is moved, substantially increase the shock dynamics between Motion Particles and oval plate liner and moving particle, the production efficiency making equipment significantly improves, and energy consumption substantially reduces. Pulverizer of the present utility model not only has ultrahigh speed air-flow in table roller jet mill to the impact of particle and friction pulverization, and the particle that ultrahigh speed motion, energy can be made huge produces collision.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1 and Figure 2, the lithium battery superfine powder disintegrating apparatus of the present embodiment, including crushing bin 1, crushing bin 1 is connected with air inlet pipe 2, with feed nozzle 11 and discharging opening 12 on crushing bin 1, the cross section of crushing bin 1 is ellipsoidal structure, feed nozzle 11 is positioned at the short shaft end side of crushing bin 1, discharging opening 12 is positioned at the center, upper surface of crushing bin 1, the inwall being positioned at the crushing bin 1 of feed nozzle 11 offside is provided with curved baffle 3, forms the circular cyclone 4 of two reverse rotations during feed nozzle 11 high speed charging after impacting curved baffle 3; Air inlet pipe 2 includes air inlet supervisor 21 and many and the air inlet air intake branches 22 that are connected of supervisor 21, air intake branch 22 interval be arranged in crushing bin 1 outer wall and with the inner space of crushing bin 1, the air inlet of air intake branch 22 is arranged along the tangential direction of circular cyclone 4.
In this utility model, the material short shaft end side from oval plate and major axis middle part are fed in raw material, the material that feed nozzle 11 sprays in crushing bin 1, reflection by curved baffle 3, make to produce in crushing bin 1 circular high-speed rotational two strands oppositely oriented, two bursts of high-speed rotational are oppositely oriented and that produce cutting force makes particle be subject to very big collision and friction in intersection area, thus better reaching the effect of classification and pulverizing, and then promote the crushing effect of crushing bin 1, it is possible to pulverize out submicron fine particle. Adopt disintegrating apparatus of the present utility model to carry out micropowder and add man-hour, it is possible to produce more short grained fine powder, and production efficiency is higher, energy consumption is lower.
Embodiment provided above is better embodiment of the present utility model, only it is used for this utility model is conveniently described, not this utility model is done any pro forma restriction, any art has usually intellectual, if in the scope without departing from the carried technical characteristic of this utility model, utilize the Equivalent embodiments that the done local of this utility model disclosed technology content is changed or modified, and without departing from technical characteristic content of the present utility model, all still fall within the scope of this utility model technical characteristic.
