Description
Scheibenrost für Feinabsiebung Durch das Aneinanderreihen von Scheibenr ostwalzen bildet sich ein mehr oder weniger langer Spalt.Disc grate for fine screening By lining up disc numbers ostwalzen a more or less long gap is formed.
Bei den bekannten Scheibenrosten hat der Spalt bei einer gegebenen Spaltbreite eine durchgehend gleichbleibende Spaltlänge.In the known disc gratings, the gap has a given Gap width a continuously constant gap length.
Diese gleichbleibende Spaltlänge wirkt sich nachteilig aus, und zwar insofern, daß längliches Siebgut durch den langen Spalt hindurchtritt.This constant gap length has a disadvantageous effect, namely to the extent that elongated screenings pass through the long gap.
Diesen Nachteil beseitigt vorliegende Erfindung, indem sie einen Rost in Vorschlag bringt, bei welchem die Spalte der Rostwalzen in Richtung des Siebgutstromes allmählich verkürzt werden. Die Spaltverkürzung kann dabei zwischen einzelnen Walzen oder Walzengruppen vorgenommen werden, -um auch solchem Siebgut, welches durch die Rostwalzen infolge der ständig vorhandenen Reibung abgenutzt und dadurch kleiner wird, den Durchtritt durch die Spalten zu wehren.The present invention eliminates this disadvantage by providing a grate brings in the proposal, in which the column of the grate rollers in the direction of the stream of screenings be gradually shortened. The gap can be shortened between individual rollers or groups of rollers are made, -um also such screenings, which by the Grate rollers worn out due to the constant friction and therefore smaller will defend the passage through the crevices.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt, und zwar zeigen: Fig, i einen solchen Scheibenrost im Querschnitt und Fig.2 den Rost im Grundriß.In the drawing, an embodiment is shown, namely show: Fig, i such a disk grate in cross section and Fig. 2 the grate in plan.
Die Walzen a, b, c, d"e, f und ä drehen sich sämtlich in ein und derselben Richtung. Das Siebgut fällt hierbei durch die Spalteh, die sich-in Richtung des Siebgutstromes allmählich verkürzen, und zwar so weit, bis der Kern der dem Überlaufende zunächst gelagerten Walzen oder die ihn umgebenden Abstandsbeilageringe den Außenrand der auf dem Kern angeordneten Scheiben berühren.The rollers a, b, c, d "e, f and ä all rotate in one and the same direction. The material to be screened falls through the gap, which gradually shortens in the direction of the flow of material to be screened, until the core the rollers initially mounted on the overflow or the spacer rings surrounding it touch the outer edge of the disks arranged on the core.
Die einzelnen Walzen können beliebig zu-,einander angeordnet werden. Die Spaltlänge soll aber das Maß der Spaltbreite nicht unterschreiten.The individual rollers can be arranged in relation to one another as desired. However, the gap length should not be less than the dimension of the gap width.
