Operation principle of the present utility model is accepted:
Pre-grinding mixed material is out in charging aperture feeding powder concentrator, drop into above the spreading disk being arranged on above cage rotor, spreading disk rotarily drives material and is rotated and sheds, throw on buffer board, material after being hit further disperses, drop in the territory, powder-separating area that wind blade and cage rotor blade form, at this powder-separating space material, be subject to the sorting that cage rotor selects powder air-flow, thinner finished product materials is carried and is brought into cage rotor inside by air-flow, and enter in follow-up collecting device by wind pipe, carry out gas solid separation collection, but not the thicker material of finished product is ostracised in cage rotor outside, because Action of Gravity Field down moves to middle meal feed opening, enter the graded operation region of thickness powder.Cage rotor place selection by winnowing energy produces suction force by follow-up dusting fan, and air intake is entered by air inlet, a secondary air inlet.The residing housing of one secondary air inlet is double volute shape, and a secondary air inlet is air intake simultaneously, and the gas of entering is by the equal wind effect of wind blade, and by cage rotor, around air quantity layout is even, and adjusts gas motion tangential direction.
Material under middle meal feed opening is fallen the outward flange of wind wheel, because wind wheel is arranged on main shaft, main shaft rotation also drives wind wheel rotation, the wind wheel of rotation produces swirling eddy, form field of wind-force, in this field of wind-force, in the material falling above, larger material is because its quality is larger, its inertia is larger, be affected by gravity and move downward comparatively fast, and the strength that outwards promoted by wind wheel wind-force is less, thicker material is easier to drop into meal and collects in cylindrical shell, thinner material is subject to blowing of wind wheel wind-force, that when moving downward, outwards moves is distant, move to remote after due to Speed Reduction, peripheral space also expands, reduce or lose speed and drop in fine powder ash bucket, in fine powder ash bucket, concentrate from fine powder outlet and discharge, and thicker material falls in process at meal ash bucket, because adopting detachable sieve plate, makes by meal ash bucket, the particle that is less than sieve plate hole is down dropping into again in fine powder ash bucket in motion, improved like this efficiency of thickness stock grading.Wind wheel rotation produces air-flow, wind wheel inside will form negative pressure, at meal surge drum body side surface, several circulation air inlets have been offered, the air of collecting between cylindrical shell and grading room cylindrical shell for meal enters in meal collection cylindrical shell, and installed a return air cylindrical shell additional in meal collection inner barrel, for the circulation air of wind wheel.
Meal collect cylindrical shell top install one can up-down adjustment adjustment back-up ring, for up-down adjustment, control the partition size size of thickness material.On meal ash bucket, sieve plate is above detachable in addition, can change according to the size of fine powder amount the sieve plate of different sieve apertures, thereby reaches the size of controlling the fine powder amount in fine powder ash bucket.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection is all documented in claims.
