Described tangential entry is at least one, is evenly to distribute along circumference under a plurality of situations.
Described axial inlet has been opened a fan-shaped opening on the upper plate on cylindrical shell top or fan-shaped opening expands to annular opening, downward oblique fixedly import deflector is at least two between discharge core pipe excircle in opening and the barrel wall, evenly distribute along circumference in import department, making logistics is tangential motion from the axially-movable transition.
Described import deflector is surface plate or curved slab.
Described upper plate is that level or inclination are fixed on the cylindrical shell upper end.
The section configuration of described cylindrical shell and cone can be circle, square or rectangle.
Described cone is reverse taper, right circular cone or isometrical cylindrical shell.
Described drag reduction bar section configuration is that circle, rectangle, ellipse, drop type or angle circle are compound.
Described drag reduction bar upper end is fixed on the upper plate on cylindrical shell top, discharges on the core pipe or on the import deflector, and the lower end is fixed on separated object outlet or the cone; When lower end fixedly the time, but the upper end cantilever; When upper end fixedly the time, but the lower end cantilever.
A=0-360 ° at the installation position angle of described drag reduction bar; Be installed in and discharge between core pipe excircle and the cylinder inboard wall, in particular cases be installed in less than certain position of discharging core pipe radius; During many drag reduction bar combinations, can be uniform on circumference, also can be non-uniform, can be fixing as single drag reduction bar, framework of one-tenth also capable of being combined is fixed with housing again.
Effect intentionally of the present invention is after material enters from import, makes logistics produce separation for rotatablely moving.Adopt the measure of drag reduction bar drag reduction, implement easily, investment cost is low, stability and good reliability, the anti-drag type centrifugal separation equipment must have been given play to greater role.
