SCREENING DEVICE FOR SOLIDS AND METHOD FOR THE SCREENING OF SOLIDS

摘要

IN ORDER TO ALLOW RELIABLE AND FAULT-FREE SCREENING OF SOLIDS (R) BY MEANS OF A SCREENING DEVICE (1) HAVING AS SIMPLE A DESIGN AS POSSIBLE, THERE IS PROVIDED, ACCORDING TO THE INVENTION, AS A SCREENING DEVICE (1) A SPIRAL (10) FORMED BY A HELICALLY WOUND ROD (8) OR A PLURALITY OF SUCH RODS (8) WHICH IS OR ARE ROTATABLE ABOUT THE LONGITUDINAL AXIS (3). THE SOLIDS (R) ARE INTRODUCED FOR SCREENING, PREFERABLY WITH THE AID OF AN ALIGNING DEVICE (2) FOR ELONGATE SOLID FRAGMENTS (16), INTO THE INTERIOR (11) FORMED BY THE ROD (8). THE SPIRAL (10) HAS, IN PARTICULAR, A CURVATURE, SO THAT JAMMED SOLID FRAGMENTS (R) ARE AUTOMATICALLY RELEASED. THE SCREENING DEVICE (1) SERVES, IN PARTICULAR, FOR THE SCREENING OF PYROLYSIS RESIDUE.THE MOST ILLUSTRATIVE DRAWING IS (FIGURE 1)
