Abstract
The utility model relates to a centrifugal type powder selecting machine, which is characterized in that a small vane forms a stick shape, or the small vane are arranged in an oblique mode. The utility model has the advantages of stable airflow, and thereby, the powder selecting effect is good. The utility model is suitable for dry type classifying work.
Description
The utility model belongs to a kind of centrifugal powder equipment that selects that separates the thickness particle.
Centrifugal classifier is a kind of traditional screening installation, because its simple shape and blade of little fan blade that mainly produces separating effect is too wide, makes that its grinding efficiency is low and the sorting powder particle size is thicker.
The purpose of this utility model is in order to overcome existing centrifugal classifier above shortcomings, a kind of powder concentrator that the powder and fine powder granularity is little and grinding efficiency is high that selects to be provided.
The purpose of this utility model is realized by following technical scheme: the big width that changes the vanelets of horizontal device is little width or is the rod shape that the comparable prophyll sheet of the blade of this shape device is more.The utility model also can change little fan blade into inclined type by horizontal setting, be that vanelets space in powder concentrator tilts to install, the top of tilting little fan blade is near the internal face of inner barrel, and the bottom is away from the internal face of inner barrel, and the tilting little fan blade that install on symmetrical two sides constitutes an inverted truncated cone shape.
The utility model is because the little fan blade of the horizontal rod shape of employing is scratched lessly to the air-flow in the graded region, so it is distinguished and admirable comparatively stable, so the grinding efficiency height, and when the little fan blade of the horizontal rod shape of installation, its sorting fineness can be littler.Tilting little fan blade can make steady air current when rotated, makes the fine powder product selected many and all even granularity is little.Two kinds of generally separately independent employings of different little fan blades also can be mixed employing.Be improved powder concentrator grinding efficiency and choose thinner product characteristics of above-mentioned two kinds of little fan blades of modified.Can be used for the dry classification operation.
Description of drawings:
Accompanying drawing is the utility model example structure figure.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in drawings, the utility model improvement of being on the basis of existing technology to be done.The transmission device 1 of powder concentrator is on top, it makes main shaft 3 rotations, spreading disk 11 is equipped with in main shaft 3 bottoms, the top of spreading disk 11 fixed fan blade carriage 10, big blade 4 is equipped with on the top of fan blade carriage 10, tilting little fan blade 9 (or the little fan blade 8 of horizontal rod shape) is equipped with in the bottom of fan blade carriage 10, and the inner and outer shell of powder concentrator constitutes the external space 7 and interior space 6, and the connection of interior outer room is realized by return air leaf 12.When material to be separated is given fashionable from charging aperture 2, fall on the spreading disk 11 of rotation and be subjected to action of centrifugal force spread inside space 6 around, big blade produces the circulating current that rises with main axis rotation, circulating current upwards enters the external space 7 from interior space 6, enter interior space 6 and rising again from return air leaf 12 again downwards from the external space 7, by spreading disk 11 spread to around material thickness in ascending air begin to separate, bulky grain is big because of self gravitation, directly fall into down inner core 13 and be discharged from outside the machine, the particle of thin part is promoted by ascending air, enter tilting little fan blade 9 (or the little fan blade 8 of horizontal rod shape) zone, carry thicker particle and little fan blade bump in the ascending air secretly and stall falls into down inner core 13 also outside the discharge machine.Fine powder then rises with ascending air and enters the external space 7, and forms product outside machine is discharged in the external space 7 bottoms.
But the width of blade top of tilting little fan blade 9 is narrow, the bottom is wide, also width unanimity up and down.The blade of the little fan blade 8 of horizontal rod shape is the rod shape, and rod shape cross section can be circle, square or prismatic or other is irregularly shaped, also can be the arrow gauge shape.
