Die bisher bekannt gewordenen Walzensortirapparate sind unter der Voraussetzung construirt, dafs es unbedingt erforderlich sei, die Durchtrittsöffnung als allseitig geschlossene Figur zu behandeln. Dies ist aber nicht unter allen Umständen der Fall, weil doch die Kohle in der Regel in Würfelform oder in ähnlicher Gestalt zerbröckelt. Die platte Form findet sich so gut wie gar nicht bei Kohlen und Kleinkohlen. Aus diesem Grunde wird der vorliegenden Erfindung gemäfs die Durchtrittsöffnung der Walzensortirapparate zickzackförmig gestaltet. Man erreicht damit den folgenden Vortheil: Unter der Voraussetzung, dafs die einzelnen Durchtrittsöffnungen allseitig geschlossen sind, liegen die Vorsprünge zweier benachbarter Walzen dicht neben einander. Auf diese Weise ist es unmöglich, dafs Kohlenstückchen, welche der Kaliberweite gemäfs nach unten hindurchfallen sollten, unmittelbar ihren Weg in waagrechter Richtung fortsetzen, indem sie von den Vorsprüngen der einen Walze auf diejenigen der nächstfolgenden übertreten.The previously known roller sorting apparatus are under the prerequisite designed that it was absolutely necessary to keep the passage opening closed on all sides Handle figure. But this is not the case under all circumstances, because the Coal usually crumbled into cubes or similar shapes. The flat shape is hardly found at all in coals and small coals. Because of this, According to the present invention, the passage opening of the roller sorting apparatus is zigzag designed. The following advantage is thus achieved: Provided that the individual passage openings are on all sides are closed, the projections of two adjacent rollers are close to each other. In this way it is impossible for pieces of coal which, according to the size of the caliber, should fall through, directly continue their path in the horizontal direction by moving from the projections of one roller to those of the next trespass.
Ein vorliegender Erfindung gemäfs angeordneter Walzensortirapparat ist auf der beiliegenden Zeichnung in zwei Ausführungsformen im Grundrifs veranschaulicht. A roller sorting apparatus arranged in accordance with the present invention is shown in the accompanying sheet Drawing illustrated in two embodiments in the Grundrifs.
Beim Ausführungsbeispiel Fig. ι und 2 ist die Zickzackform der Durchtrittsöffnung α dadurch geschaffen, dafs die aus einem Cylinder und zwei Kegeln gebildeten Vorspränge b der einen Walze den Lücken c der anderen Walze gegenüberstehen. Um die Kohlenstücke oder dergleichen noch wirksamer daran zu hindern, dafs sie durch die den äufseren, mit der verhältnifsmäfsig gröfsten Geschwindigkeit sich drehenden Theil der Vorsprünge über die ihrer Gröfse entsprechenden Lücken hinweggeführt werden, und zu bewirken, dafs diese. Kohlenstücke vielmehr in Richtung der Walzenachsen abgelenkt und auf den im Durchmesser geringeren, das Zurückfallen erleichternden Theil der Walze selbtthätig befördert werden, sind gemäfs Fig. 2 stark gerundete oder scharfkantige Vorsprünge b1 und Lücken c1 vorgesehen. In the embodiment of FIGS. 1 and 2, the zigzag shape of the passage opening α is created in that the projections b of one roller, formed from a cylinder and two cones, face the gaps c of the other roller. In order to prevent the pieces of coal or the like still more effectively from being carried over the gaps corresponding to their size by the part of the projections rotating at the relatively greatest speed on the outside, and to cause them to do so. Rather, pieces of coal are deflected in the direction of the roller axes and automatically conveyed to the part of the roller which is smaller in diameter and which facilitates falling back, strongly rounded or sharp-edged projections b 1 and gaps c 1 are provided according to FIG.
Beim Ausführungsbeispiel Fig. 1 können die Flächen d und d1, beim Äusführungsbeispiel Fig. 2 diejenigen b1 c1 d2 gerieft sein.In the embodiment of FIG. 1, the surfaces d and d 1 , in the embodiment of FIG. 2, those b 1 c 1 d 2 can be grooved.
