For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of classifying screen, comprise casing 1, feed arrangement 2, screen cloth, vibrating shaft 3 and discharging opening, the top of casing 1 is provided with feed arrangement 2, feed arrangement 2 comprises charging aperture 21, delivery chute 22, delivery chute 22 is arranged on charging aperture 21 bottoms, screen cloth is positioned at delivery chute 22 belows, comprise the first screen cloth 4, the second screen cloth 5 and the 3rd screen cloth 6, the first screen cloth 4 is inclined at casing 1 top, the second screen cloth 5 is arranged on casing 1 middle part, incline direction is contrary with the first screen cloth 4, the 3rd screen cloth 6 is arranged on casing 1 bottom, incline direction is identical with the first screen cloth 4, sieve screen apertures diameter successively from big to small, delivery chute 22 is obliquely installed, and incline direction is contrary with the first screen cloth 4, vibrating shaft 3 is arranged on screen cloth, discharging opening is arranged on casing 1, comprise the first discharging opening 7, the second discharging opening 8, the 3rd discharging opening 9 and the 4th discharging opening 10, the first discharging opening 7 is corresponding with the first screen cloth 4 least significant ends, the second discharging opening 8 is corresponding with the second screen cloth 5 least significant ends, the 3rd discharging opening 9 is corresponding with the 3rd screen cloth 6 least significant ends, the 4th discharging opening 10 is arranged on casing 1 bottom.
Further, the screen cloth being arranged on casing 1 is dismountable.
Further, delivery chute 22 is L shaped.
Further, the angle of inclination of screen cloth is to be 20 °-30 ° with horizontal direction.
Further, it is trapezoidal that discharging opening is, and its cross section near casing one side is less than the cross section away from casing one side.
Advantage and the good effect that the utlity model has are: a kind of classifying screen of the present utility model, by the setting of feed arrangement, make charging not during sub-sieve, first to the raw material processing of circling round, other size materials of separation different size material surface attachment, to reach better grading effect, in addition, the delivery chute arranging with the first screen cloth rightabout, can be so that material be while entering classification, on screen cloth, distribute more even, be beneficial to screening; Being obliquely installed of screen cloth, make to fall into screen cloth material, under the effect of gravity, in the time of down sliding, the sieve aperture from screen cloth that particle diameter is little is missed, and drop on next screen cloth, and the large material of particle can flow out along screen cloth face from bottom, the double action of feed arrangement and inclination screen cloth, makes screening effect better; Vibrating shaft is set on screen cloth, avoids the vibration of whole classifying screen casing, power consumption is little, long service life, and grading effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of classifying screen of the utility model.
In figure: 1, casing, 2, feed arrangement, 21, charging aperture, 22, delivery chute, 3, vibrating shaft, the 4, first screen cloth, the 5, second screen cloth, the 6, the 3rd screen cloth, the 7, first discharging opening, the 8, second discharging opening, the 9, the 3rd discharging opening, the 10, the 4th discharging opening
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate architectural feature of the present utility model:
As shown in Figure 1: a kind of classifying screen, comprise casing 1, feed arrangement 2, screen cloth, vibrating shaft 3 and discharging opening, the top of described casing 1 is provided with feed arrangement 2, described feed arrangement 2 comprises charging aperture 21, delivery chute 22, delivery chute 22 is arranged on charging aperture 21 bottoms, described screen cloth is positioned at delivery chute 22 belows, comprise the first screen cloth 4, the second screen cloth 5 and the 3rd screen cloth 6, the first screen cloth 4 is inclined at casing 1 top, the second screen cloth 5 is arranged on casing 2 middle parts, incline direction is contrary with the first screen cloth 4, the 3rd screen cloth 6 is arranged on casing 1 bottom, incline direction is identical with the first screen cloth 4, three sieve screen apertures diameters successively from big to small, described delivery chute 22 is obliquely installed, and incline direction is contrary with the first screen cloth 4, described vibrating shaft 3 is arranged on screen cloth, described discharging opening is arranged on casing 1, comprise the first discharging opening 7, the second discharging opening 8, the 3rd discharging opening 9 and the 4th discharging opening 10, the first discharging opening 7 is corresponding with the first screen cloth 4 least significant ends, the second discharging opening 8 is corresponding with the second screen cloth 5 least significant ends, the 3rd discharging opening 9 is corresponding with the 3rd screen cloth 6 least significant ends, the 4th discharging opening 10 is arranged on casing 1 bottom.
The screen cloth being arranged on casing 1 is dismountable, is convenient for changing the screen cloth of different size, and equipment interoperability is high.
Delivery chute 22 is L shaped, and the graphite at charging aperture 21 places is before classification, under the shock by L shaped feeding groove 22, friction, can the fine particle being attached on graphite is separated, and to reach better grading effect.
Delivery chute 22 is for what be obliquely installed, and incline direction is contrary with the first screen cloth 4, while making graphite classification, distributes more even on screen cloth, can not retain, and classification efficiency is high.
The angle of inclination of screen cloth is to be 25 ° with horizontal direction, is conducive to final graphite Rapid Flow on each screen cloth to corresponding discharging opening.
It is trapezoidal that discharging opening is, and its cross section near casing one side is less than the cross section away from casing one side.
A kind of course of work of classifying screen is: classification graphite does not enter inverted L-shaped delivery chute 22 by charging aperture 21, under Action of Gravity Field, graphite in inclination delivery chute 22 enters the first screen cloth 4, because the aperture of screen cloth increases gradually, therefore, under the effect of the first inclination screen cloth 4 and vibrating shaft, bulky grain graphite enters the first discharging opening 7 along the first screen cloth 4, remaining graphite enters the second screen cloth 5, under the effect of the second inclination screen cloth 5 and vibrating shaft, middle granular graphite enters the second discharging opening 8 along the second screen cloth 5, remaining graphite enters the 3rd screen cloth 6, under the effect of the 3rd screen cloth 6 and vibrating shaft, granule graphite enters the 3rd discharging opening 9 along the 3rd screen cloth 6, remaining molecule graphite enters the 4th discharging opening 10 of casing bottom, complete the screening operation of whole graphite classification.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
