Visualization of Particles Transport by Discharging Plates

Abstract

A Rotating Drum Type Solid-Liquid Separator which operates in two different modes : one is a separating mode and another a discharging one is proposed by the authors. It is necessary to discharge solid particles out of the drum which pile up on the drum wall as soon as possible. In this paper, during the discharging mode, the flow visualized experiments were carried out using a two-dimensional model, in order to clarify the effects of the discharging plates. As a result, it was found that the aspect of particles transportation changes the distance of the discharging plates and a clearance between the plate edge and the surface of the particles bed and there exists the most probable distance of plates and clearance. In the case of large distance of the discharging plates, the transportation by the scour is predominant
