Description
Technical field
The present invention relates to graphite classification technique field, particularly one rotates classifying screen.
Background technology
Graphite as the advantage of lithium ion battery negative material is: voltage low (oxidation-reduction pair close to lithium metal), security is high, cost is low, lithium ion inserts that the current potential of graphite linings is low and smooth, good cycling stability, irreversible capacity are little, but also there is obvious shortcoming: poor with the compatibility of electrolyte, high rate during charging-discharging is poor, first charge-discharge time graphite linings is peeled off because of the common embedding of solvent molecule, thus cause reduce electrode life.Conventional solution is to the process of graphite material modifying surface, and first native graphite will be pulverized and be processed into qualified spherical graphite by various modified graphite.Different industries is strict to the granularity requirements of spherical graphite, and in process, the intermediate products of production are more, can not meet industry requirement.The classifying screen of current employing mostly is vibration separation screen, fragile, and vibration noise is large, stationarity is poor, and grading effect is not good, and efficiency is low, less economical.
Summary of the invention
The problem to be solved in the present invention is to provide and a kind of rotates classifying screen, screening process steadily, screening device can be avoided to vibrate, classification efficiency is high, long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of rotation classifying screen, comprise frame 1, motor 2, reductor 3, sieve bucket 4, feed hopper 5, elastic supporting plate 6 and sieve nest, the output shaft of motor 2 connects sieve bucket 4 by reductor 3, sieve bucket 4 two ends are closed, sieve bucket 4 is inclined in frame 1, sieve bucket 4 top connects feed hopper 5, end is provided with elastic supporting plate 6, sieve bucket 4 inner radial direction is provided with sieve nest, sieve nest comprises the first compass screen surface 7 and the second compass screen surface 8 successively along sieve bucket 4 incline direction, and the aperture of compass screen surface reduces successively, the first discharging opening 9 is respectively equipped with on the downside of the screen box 4 of three regional locations that corresponding compass screen surface is separated into sieve bucket 4, second discharging opening 10 and the 3rd discharging opening 11, and be equipped with valve on the downside of the sieve bucket 4 of corresponding each discharging opening.
Further, sieving the angle of inclination of bucket 4 is be 6-15 ° with horizontal direction.
Further, sieve bucket 4 and be provided with visual window.
Further, elasticity glueballs is provided with in sieve bucket 4.
Further, pressing mechanism is provided with in feed hopper 5.
The advantage that the present invention has and good effect are: one of the present invention rotates classifying screen, by the setting of compass screen surface, retained respectively by the particle of different-diameter size, grading effect is good, mixing appears in the particle avoiding different-diameter, in addition, this rotation classifying screen mainly utilize revolving force but not common vibration force to reach the object of classification, avoid the loss of complete machine, power consumption is little, long service life, structure is simple, good economy performance.

Detailed description of the invention
Architectural feature of the present invention is further illustrated below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of rotation classifying screen, comprise frame 1, motor 2, reductor 3, sieve bucket 4, feed hopper 5, elastic supporting plate 6 and sieve nest, the output shaft of motor 2 connects sieve bucket 4 by reductor 3, sieve bucket 4 two ends are closed, sieve bucket 4 is inclined in frame 1, sieve bucket 4 top connects feed hopper 5, end is provided with elastic supporting plate 6, sieve bucket 4 inner radial direction is provided with sieve nest, sieve nest comprises the first compass screen surface 7 and the second compass screen surface 8 successively along sieve bucket 4 incline direction, and the aperture of compass screen surface reduces successively, the first discharging opening 9 is respectively equipped with on the downside of the screen box 4 of three regional locations that corresponding compass screen surface is separated into sieve bucket 4, second discharging opening 10 and the 3rd discharging opening 11, and be equipped with valve on the downside of the sieve bucket 4 of corresponding each discharging opening.
The elasticity support plate 6 that sieve bucket 4 end is provided with, for support screen bucket 4, ensure that stationarity when rotating classifying screen work, reduces noise, improve classification performance.
The angle of inclination of sieve bucket 4 be 6-15 ° with horizontal direction, preferably 10 °, and the material sieved in bucket more easily travels forward, and classification efficiency is high.
Sieve bucket 4 is provided with visual window, is convenient to check equipment operation situation and maintenance.
Be provided with elasticity glueballs in sieve bucket 4, be used for clashing into compass screen surface, prevent compass screen surface from occurring blocking.
