The specific embodiment

Among Fig. 1 and Fig. 2, manual sandstone selection by winnowing powder remover contains cyclone separator 1, separating chamber 22, vertical drive shaft 3, variable-frequency motor, cage rotor 2, blower fan 9, fine sand collection cone 21, medium sand collection cone 20, coarse sand sorting unit.Cyclone separator 1 be positioned at separating chamber 22 around; The air inlet of cyclone separator 1 interlinks through the top of pipeline and separating chamber 22; The air outlet of cyclone separator 1 links to each other with the air inlet of blower fan 9 through pipeline 7, and the meal outlet 17 of cyclone separator 1 is positioned at its lower end.Belt wheel on the blower fan 9 links to each other with the belt wheel that motor 13 is provided with through belt.Vertical drive shaft 3 is installed on through bearing block on the top of separating chamber 22, and the upper end of vertical drive shaft 3 is positioned at the outside, its lower end part at the top of separating chamber 22 in the inside of separating chamber 22.Variable-frequency motor is arranged on the top of separating chamber 22, and the belt wheel that is arranged in the variable-frequency motor rotating shaft links to each other with belt wheel 4 on being arranged on vertical drive shaft 3 upper ends through belt, and is not shown in the figures.Cage rotor 2 is arranged on the bottom of vertical drive shaft 3.Fine sand collection cone 21 is arranged on the below of cage rotor 2, is uniformly distributed with on the last end periphery of fine sand collection cone 21 arc deflector 23 is set, and the lower end of fine sand collection cone 21 is provided with fine sand discharge nozzle 18.Medium sand collection cone 20 is arranged on the below of separating chamber 22, and medium sand collection cone 20 is provided with air intake passage 25.Said coarse sand sorting unit by the V-arrangement pipe, break up plate 11, graded plate 5 constitutes; The left end of V-arrangement pipe is that air inlet 8, right-hand member are air outlet 16; Break up the side that plate 11 is successively set in the V-arrangement pipe from top to bottom and is positioned at air inlet 8; Graded plate 5 is successively set in the V-arrangement pipe from top to bottom and is positioned at a side of air outlet 16, breaks up the segment distance of being separated by between plate 11 and the graded plate 5 and forms a blanking channel, and the lower end of V-arrangement pipe is provided with coarse sand discharge nozzle 14; The charging aperture of this coarse sand discharge nozzle 14 is positioned at nethermost below of breaing up plate 12 and nethermost graded plate 6; The V-arrangement pipe is provided with feed pipe 24, and the discharging opening of feed pipe 24 is positioned at uppermost top of breaing up plate 10, and the air inlet of V-arrangement pipe is connected through the air outlet of tube connector with said blower fan 9; The air outlet 16 of V-arrangement pipe links to each other through the air intake passage 25 that transition conduit 19 and medium sand collection cone 20 are provided with, and the lower end of transition conduit 19 is provided with medium sand discharge nozzle 15.When above-mentioned powder remover is worked; After material gets into the coarse sand sorting unit from feed pipe 24; Fall into uppermost the breaing up on the plate 10 in the V-arrangement pipe; On the one hand material is broken up the whereabouts step by step through what respectively break up plate, and the air-flow that got into by the left side of material dispels and is in suspended state on the other hand, and coarse sand is then discharged from the coarse sand discharge nozzle 14 of V-arrangement pipe lower end.The material that suspends gets between each graded plate 5 with air-flow; Because the deceleration of air-flow and the deflection of direction; Lose kinetic energy after coarse sand in the material and each graded plate 5 bump and drop to coarse sand discharge nozzle 14 and be discharged from, and the outer surface of the inner surface of medium sand and medium sand collection cone 20 and fine sand collection cone 21 loses kinetic energy and drops in the medium sand discharge nozzle 15 after bumping and is discharged from.After containing the air-flow entering separating chamber 22 of fine sand and powder, under the effect of arc deflector 23, rotate, produce the double action of centrifugal sedimentation and gravitational settling, fine sand falls into fine sand collection cone 21, is discharged by fine sand discharge nozzle 18.Powder passes cage rotor 2 with air-flow; Under the effect of cage rotor 2, throw away fine sand; Falling into fine sand collection cone 21 backs behind the fine sand bump arc deflector 23 is discharged by fine sand discharge nozzle 18; Pulverized coal borne air flow gets into cyclone separator 1 laggard promoting the circulation of qi to be separated admittedly, and isolated powder is discharged by the meal outlet 17 of cyclone separator 1, and clean air circulates through the import that pipeline 7 gets into blower fan 9.From on can find out that above-mentioned powder remover can be divided into coarse sand, medium sand, fine sand, powder with artificial sand, thereby realize the good grating of artificial sand, this has not only saved the input of equipment, and has reduced production cost.
