Description
Rostartige Vorrichtung zum Klassieren von Schüttgut Die Erfindung bezieht sich auf eine rostartige Vorrichtung zum Klassieren von steinigem Schüttgut nach der Komgröße mittels einer gelochten Platte aus Gummi oder einem gummiähnlichen Kunststoff. Während des Klassierens kommt es immer vor, daß das Gut die Lochungen der Platte verstopft. Man muß fortlaufend die Platte durch Anschlagen oder dergleichen Mittel säubern. Hierdurch entstehen Betriebsstörungen, die insbesondere durch Ruhepausen sich bemerkbar machen.Grate-like device for classifying bulk material The invention relates to a grate-like device for classifying stony bulk material according to grain size by means of a perforated plate made of rubber or a rubber-like plastic. During the classification, it often happens that the material clogs the holes of the plate. One must continuously clean the plate by hitting or similar means. This results in operational disruptions that are particularly noticeable through breaks.
Die Erfindung hat sich zur Aufgabe gestellt, den aufgezeigten Nachteil auf einfachste Weise zu beheben. Ihr Wesen wird insbesondere darin gesehen, daß in Rutschrichtung des zu klassierenden Gutes zwischen gelochten Reihen auf der gelochten Klassierplatte nach oben vorspringende Rippen, Leisten od. dgl. vorgesehen sind, deren Querschnitte sich zur glatten Ebene verjüngen und gegenüber den Breiten der Lochungen einen geringeren Durchgang haben.The invention has set itself the task of addressing the disadvantage shown to fix in the easiest way. Its essence is seen in particular in that in the slip direction of the goods to be classified between perforated rows on the perforated Classifying plate upwardly projecting ribs, strips or the like are provided, whose cross-sections taper to a smooth plane and compared to the widths of the Holes have a smaller passage.
Der Erfindungsgegenstand ist in der Zeichnung durch ein Ausführungsbeispiel schematisch dargestellt, und zwar zeigt Ab b. 1 die Draufsicht auf ein Sieb gemäß der Erfindung, A b b. 2 einen Querschnitt durch den Gegenstand der Ab b. 1. The subject of the invention is shown schematically in the drawing by means of an exemplary embodiment, namely shows Ab b. 1 the top view of a sieve according to the invention, A b b. 2 shows a cross section through the object of Fig. B. 1.
Die Vorrichtung zum Klassieren von steinigem Gut nach der Komgröße besteht aus einer ebenen gelochten Platte aus Gummi oder einem gummiähnlichen Kunststoff. Diese Platte hat bei dem in der Zeichnung dargestellten Ausführungsbeispiel Reihen von rechteckigen Lochungen 1 und runden Lochungen 2. Es liegt im Sinne der Erfindung, von der Plattenebene nach oben Rippen, Leisten 3 od. dgl. vorspringen zu lassen, die in Rutschrichtung des zu klassierenden Gutes angeordnet sind.The device for classifying stony material according to the grain size consists of a flat, perforated plate made of rubber or a rubber-like plastic. In the embodiment shown in the drawing, this plate has rows of rectangular perforations 1 and round perforations 2. It is within the meaning of the invention to have ribs, strips 3 or the like protrude from the plane of the plate upwards, which protrude in the direction of the slide to be classified Good are arranged.
Die Rippen, Leisten od. dgl. weisen einen sich zur Plattenebene 4 geneigten, verjüngten Querschnitt auf. Hierdurch entstehen Durchgänge 5, die gegenüber den Lochungen 1 bzw. 2 einen geringeren Durchgang haben. Das hat zur Folge, daß an der Außenfläche 6 der vorspringenden Rippen, Leisten od. dgl. eine Art Vorklassierung erfolgt. Die durch die Durchgänge 5 hindurchfallenden Kömungen fallen mit Sicherheit durch die Lochungen 1 bzw. 2 hindurch, weil sie infolge der Vorklassierungen gegenüber den Lochungen 1, 2 kleiner sind. Auf diese Weise ergibt sich der Vorteil, daß die Körnungen nicht mehr die Lochungen 1, 2 in der Platte verstopfen können. Daraus ergibt sich eine wartungslose Betriebszeit. Es hat sich als vorteilhaft herausgestellt, die gelochte Platte in Rutschrichtung des zu klassierenden Gutes auf nebeneinander angeordneten starren Längsträgem aufzulagern.The ribs, strips or the like have a tapered cross section that is inclined to the plane of the plate 4. This creates passages 5 which have a smaller passage than the perforations 1 and 2, respectively. This has the consequence that a kind of pre-classification takes place on the outer surface 6 of the protruding ribs, strips or the like. The granules falling through the passages 5 will definitely fall through the perforations 1 or 2, because they are smaller than the perforations 1, 2 as a result of the pre-classifications. In this way there is the advantage that the grains can no longer clog the holes 1, 2 in the plate. This results in a maintenance-free operating time. It has been found to be advantageous to support the perforated plate in the sliding direction of the goods to be classified on rigid longitudinal beams arranged next to one another.
Die starren Längsträger haben voneinander einen Abstand 8, welcher der Zugfestigkeit einer belasteten Platte entspricht, die elastische Eigenschaften aufweist.The rigid longitudinal members have a distance 8 from one another which corresponds to the tensile strength of a loaded plate which has elastic properties.
Infolge dieser Ealstizität entstehen Schwingungen der ' Klassierplatte, die ein Festsetzen von grobkömigem Gut und ein Ansetzen von feinkömigem Gut verhindern.As a result of this Ealstizität caused vibrations of 'classifying that prevent binding of coarse-grained asset and an attaching of feinkömigem Good.
Dadurch ist die Voraussetzung gegeben, die Klassierplatte aus einem Gummi oder einem gummiähnlichen Kunststoff herzustellen, der ausschließlich verschleißfeste Eigenschaften aufweist.This is the prerequisite for the classification plate from one To produce rubber or a rubber-like plastic that is exclusively wear-resistant Has properties.
