Liquid or sludge elevator auger - has spiral surface profile line forming acute angle with axis open to downwards side

摘要

The elevator auger handles liquids, sludge etc., being partly enclosed by a trough and rotating about an axis inclined to the horizontal. with the axis (z) inclined to the horizontal at an angle between 30-40 deg., the generating profile line(10, 11, 12) of the spiral surface (7, 8, 9) forms a straight line inclined to the axis, or a curve. The line, or the tangent of the curve, forms with the axis an acute angle open towards the downwards side.
