The aim of the invention is to provide a sure and trouble-free sieving of a solid material (R) using a sieving device (1) having an arrangement which is as simple as possible. To this end, a spiral (10) formed by a rod (8) which is wound in a helicoidal manner, or a plurality of such rods (8) are provided as a sieving device. Said rod(s) (8) can rotate around a longitudinal axis (3). For sieving, the solid material (R) is introduced into the inner space (11) formed by the rod (8), preferably with the assistance of an aligning device (2) for longitudinally extended solid material parts (16). The spirals (10) comprise, in particular, a bend so that the lodged solid materials (R) can automatically detach themselves. The sieving device (1) is especially suited for sieving pyrolysis residual material.
L'objectif de l'invention est de permettre un criblage, plus sûr et sans dérangements de matière solide (R), cela au moyen d'un dispositif de criblage (1) d'une conception aussi simple que possible. A cet effet, on utilise, comme dispositif de criblage (1), une spirale (10) formée d'une tige (8) ou de plusieurs tiges (8) enroulée(s) de façon hélicoïdale, qui peut/peuvent être entraînée(s) en rotation autour de l'axe longitudinal (3). Dans l'espace intérieur (11) formé par la tige (8), la matière solide (R) est, pour être criblée, de préférence introduite à l'aide d'un dispositif d'alignement (2) pour corps solides (16) de forme allongée. La spirale (10) comporte en particulier une courbure telle que les corps solides (R) coincés se libèrent automatiquement. Le dispositif de criblage (1) sert en particulier au criblage de matière résiduelle de pyrolyse.
