The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The utility model provides a kind of sieve materials device.As depicted in figs. 1 and 2, the sieve materials device comprises: screen drum 10, screen drum 10 comprise charging aperture 11 and discharging opening 12, and charging aperture 11 and discharging opening 12 are separately positioned on the two ends of screen drum 10, and the barrel of screen drum 10 is provided with a plurality of sieve apertures 13; Agitator 20, agitator 20 is movably arranged in the screen drum 10.Because agitator 20 is movably arranged in the screen drum 10, thereby (for example: the polysilicon in the silicon material) in screen drum 10, be able to abundant stirring make the sieve material, increase the contact probability of sieve material with sieve aperture 13, and prolonged the holdup time of sieve material in screen drum 10, thereby improved sieve material efficient.Simultaneously, the sieve materials device in the utility model has characteristics simple in structure, low cost of manufacture.Preferably, agitator 20 drives by motor.
When using the sieve materials device in the utility model, the sieve material enters in the screen drum 10 from charging aperture 11, and under the effect of agitator 20, the sieve material fully contacts with screen drum 10, size is sifted out less than the sieve material of sieve aperture 13 diameters, size is discharged from discharging opening 12 greater than the sieve material of sieve aperture 13 diameters, thereby makes small size be separated with large-sized sieve material.
Preferably, the sieve material that obtains after the sieve materials device screening in the utility model can be the sieve material (undersized sieve material) that sifts out from sieve aperture 13, also can be the sieve material (large-sized sieve material) of discharging from discharging opening 12.It is that example describes (obviously, this silicon material is the silicon material that obtains after should sifting out) from sieve aperture 13 less than the silicon material of 8mm that the utility model obtains diameter with needs.
Preferably, as shown in Figure 1, screen drum 10 is inclined relative to horizontal setting.Further, the inclination of the direction to its discharge end down arranges screen drum 10 from its feed end.Just, the vertical range of charging aperture 11 and horizontal plane is greater than the vertical range of discharging opening 12 with horizontal plane.Because screen drum 10 is inclined relative to horizontal setting, thereby make the sieve material in the screen drum 10 have a fixing flow direction, discharge from screen drum 10 thereby be conducive to the sieve material, so that follow-up sieve material injects screen drum 10 continuously, and then improved sieve material efficient.In a specific embodiment, screen drum 10 angle of inclination with respect to the horizontal plane is 15 degree.Preferably, screen drum 10 angle of inclination with respect to the horizontal plane can be 0 degree to 90 degree.
Preferably, screen drum 10 is along its axial rotation.Because screen drum 10 is along its axial rotation, thereby the constantly rolling screen drum 10 in of sieve material, thereby increased the contact probability of sieve material with sieve aperture 13, made that small size sieve material is easier to be spilt from sieve aperture 13, and then improved sieve and expected efficient.Because screen drum 10 constantly rotates, even thereby the sieve material be stuck on the sieve aperture 13, fall down in the time of also can be on screen drum 10 rotates to, thereby reduced the plugging rate of sieve aperture 13, further improved sieve and expected efficient.
Preferably, as shown in Figure 2, sieve aperture 13 is uniformly distributed on the barrel of screen drum 10.Because sieve aperture 13 is uniformly distributed on the barrel of screen drum 10, thereby when screen drum 10 rotated, the sieve material still can spill from sieve aperture 13 smoothly, and can not occur having only screen drum 10 could sieve the situation of material at ad-hoc location, thereby has improved the efficient of sieve material.Further, the diameter of sieve aperture 13 is 9mm.Certainly, the diameter of sieve aperture 13 can be carried out different settings according to the needs of each producer.
Preferably, agitator 20 comprises rotating shaft 21 and projection 22, and projection 22 is arranged on the outer surface of rotating shaft 21.Because projection 22 is arranged on the outer surface of rotating shaft 21, thereby when rotating shaft 21 rotations, projection 22 motions in screen drum 10 along with the rotation of rotating shaft 21 fully contact with screen drum 10 thereby stir the sieve material.In a preferred embodiment, projection 22 is barred body or cones that a plurality of intervals arrange, and the shape of agitator 20 is similar to mace.
