Description
Scheibenrollenrost mit zwischen den Scheiben angeordneten Abstreichern Kaliber- und Scheibenroste, deren Kalibrierung durch offene oder geschlossene Abstreicher sauber gehalten wird, sind mehrfach bekannt geworden. Enge Kalibrierungen ergeben bei großen runden Scheiben- und Mehreckscheibenabmessungen langgestreckte Schlitze, die dazu neigen, Splitter bzw. lange Stücke usw., die die Güte der Absiebung beeinträchtigen, durchschlüpfen zu lassen.Disc roller grate with scrapers arranged between the discs Caliber and disc grids, their calibration by open or closed scrapers is kept clean, have become known several times. Tight calibrations result elongated slots in the case of large, round disc and polygonal disc dimensions, which tend to produce splinters or long pieces, etc., which impair the quality of the screening, to slip through.
Nachstehende Erfindung verhindert durch Nachschaltung eines Hilfsrostes, der durch besondere Ausgestaltung der erforderlichen Abstreicher gebildet wird, den Durchgang von langen Stücken bzw. Splittern..The following invention prevents by adding an auxiliary grate, which is formed by special design of the necessary scrapers, the passage of long pieces or splinters.
Fig. a zeigt einen Querschnitt durch Siebwalzen und Abstreicher.Fig. A shows a cross section through screen rollers and scrapers.
Fig. z zeigt eine Seitenansicht von Walzen und Abstreichern.Fig. Z shows a side view of rollers and scrapers.
Es bedeuten a die Siebwalzen, b die Walzenrippen, c und cl die Abstreicher, von denen der Übersichtlichkeit halber in der Zeichnung einige weggelassen sind und die jede Walze besitzt. d sind ihre Stützungsträger. Die konstante Spaltlänge ist mit e bezeichnet, während die veränderliche Hilfsrostspaltweite mit f bzw. f l gekennzeichnet ist. Die einzelnen Walzen a werden außerhalb der seitlichen Gleitfläche c in bekannter Weise durch Kette bzw. Kegelräder o. dgl. angetrieben.It mean a mesh rolls, the roller ribs b, c and cl the scraper, of which for clarity in the drawing, some are omitted for clarity and has the each roller. d are their supports. The constant gap length is denoted by e, while the variable auxiliary grate gap width is denoted by f or f l. The individual rollers a are driven in a known manner by chains or bevel gears or the like outside the lateral sliding surface c.
Das Siebgut kommt in der Richtung des Pfeiles k an und wird durch die Walzen infolge ihres gleichen Drehsinnes i in der Richtung des. Pfeiles h weitergefördert. Auf diesem,Wege scheidet sich alles Gut von der Größe e, x, g bzw. f, x, g ab und fällt in den Abführungsrumpf 1. Sobald das Abstreicherende k den Wert k1 erhält, wird nur noch Gut von der Größe/', x, g bzw., falls f 1 so groß wie g wird, eine Korngröße von g Kantenlänge abgesiebt. Da die Spitzen m sich auf dem Kreise n bewegen, so überschneiden erstere die Kanten k bzw. k1, wodurch eine Reinigung des Rostspaltes erfolgt.The material to be screened arrives in the direction of the arrow k and is conveyed further by the rollers in the direction of the arrow h as a result of their same direction of rotation i. In this way, all good of the size e, x, g or f, x, g separates and falls into the discharge body 1. As soon as the scraper end k receives the value k1, only good of the size / ', x, g or, if f 1 is as large as g, a grain size of g edge length is screened off. Since the tips m move on the circle n, the former intersect the edges k or k1, whereby the grate gap is cleaned.
