10. application rights requires an impurity separation method for the soft chip material that the impurity separating device of the soft chip material of novel wind spraying aid type according to any one of 1 ~ 9 realizes, it is characterized in that, comprises the following steps:
(1) treating material being entrained with soft thin slice and impurity is transported to the feed end place of cylinder, and treating material blows by airduct in cylinder, under the effect of spiral deflector, forms spiral air flow in cylinder; Treating material is with flow spiral shape flow forward in cylinder, and under the effect of gas shock power and centrifugal force, soft thin slice is constantly dispelled and overturns, wherein:
Large, the bulky impurity of density is discharged at impurity outlet because Action of Gravity Field drops on the spiral deflector bottom of cylinder, realizes being separated;
Density and the similar impurity of soft thin slice are because specific area is much smaller than soft thin slice, the weak effect together being blown afloat with soft thin slice or blow afloat is failed when the high voltage pulse wind effect of pulse wind-distributing pipe, drop on the spiral deflector bottom of cylinder at the interstitial impurity of having a rest when high voltage pulse wind and discharge at impurity outlet, and soft thin slice to fall speed slow, rising by high voltage pulse wind next time, flies in the direction step by step toward discharging opening; The impurity be separated little by little drops down bottom cylinder, and falls from impurity outlet, and soft thin slice flies out from the discharge end of cylinder;
(2) partly form crumby soft thin slice not dispelled, drop on the spiral deflector bottom of cylinder in forward movement with the impurity wrapped, be arranged at the tuyere ejection high voltage pulse wind of the pulse wind-distributing pipe of spiral deflector bottom apex edge, break up and form crumby treating material, the repeated action of high voltage pulse wind makes to form crumby soft thin slice and is separated with impurity and falls.
