Description
Setzverfahren und Setzvorrichtung zur Trennung von körnigen Stoffen nach dem spezifischen Gewicht Es sind Luftsetzmaschinen bekannt, bei denen zur Trennung von Erzen und Kohlen in Schichten verschiedenen spezifischen Ge-,vichtes mehrere aus einem stetigen Luftstrom umgewandelte, im Gegentakt arbeitende Teilluftströme benutzt werden und die Luftleitungen durch zwei versetzt arbeitende Pulserzeuger unter ständiger Veränderung des Einzelquerschnittes, aber bei gleichbleibendem Gesamtquerschnitt geöffnet und geschlossen werden.Setting method and setting device for the separation of granular materials According to the specific weight Air setting machines are known in which for separation of ores and coals in layers of different specific weights, weight several Partial air currents that are converted from a steady air flow and work in push-pull are used and the air lines by two staggered pulse generators with constant change in the individual cross-section, but with the overall cross-section remaining the same be opened and closed.
Hiervon unterscheidet sich das Verfahren gemäß der Erfindung dadurch, daß einzelne nebeneinanderliegende schmale Streifen der Beschickung des Setzbettes durch ein flüssiges oder gasförmiges Mittel in Richtung seines Stromces periodisch und parallel gegeneinander verschoben werden.The method according to the invention differs from this in that that individual, adjacent narrow strips of the loading of the bed periodically by a liquid or gaseous medium in the direction of its current and moved parallel to each other.
In der Zeichnung ist eine Vorrichtung zur Ausübung des Verfahrens gemäß der Erfindung in einer Ausführungsform beispielsweise dargestellt, und zwar zeigen Abb. i das Schema der Vorrichtung im Längsschnitt, Abb. 2 im Querschnitt und Abb.3 in schaubildlicher Darstellung eine Einzelheit. ' Im wesentlichen besteht die Vorrichtung aus einem unter dem zweckmäßig rostartigen. Setzbett i mündenden Schacht 2 für die Zuführung des flüssigen oder gasförmigen Mittels, der durch Zwischenwände 3 in mehrere nebeneinanderliegende Kanäle q. unterteilt ist. Die Zwischenwände .erstrecken sich einerseits bis zum Rast 5 und andererseits über ein Steuerorgan 6, 7 hinaus, durch das der Druck des flüssigen oder gasförmigen Mittels bestimmt werden kann.In the drawing is a device for performing the method according to the invention shown in one embodiment, for example, namely Fig. i shows the scheme of the device in longitudinal section, Fig. 2 in cross section and Fig.3 shows a detail in a diagrammatic representation. 'Essentially consists the device from one under the appropriately grate-like. Bed i opening out Shaft 2 for the supply of the liquid or gaseous medium, through partition walls 3 into several adjacent channels q. is divided. The partition walls .stretch on the one hand up to the stop 5 and on the other hand beyond a control element 6, 7, by which the pressure of the liquid or gaseous agent can be determined.
Vorteilhaft besteht das Steuerorgan, wie aus Abb.3 ersichtlich, aus einer die Wände des Schachtes 2 und die Zwischenwände 3 durchdringenden Welle 6, auf der längliche, der Höhe des Schachtes 2 sich anpassende Körper 7 befestigt sind, die in ihrer Breite annähernd der Breite der Kanäle q. entsprechen. Die einander benachbarten Körper 7 sind jeweils um 18o° zueinander verdreht, so daß bei Drehung der Welle 6 die Körper 7 entweder die Kanäle öffnen oder schließen. _ Es wird so immer abwechselnd in der einen Serie von Kanälen ein starker Druck auftreten, wogegen in den benachbarten Kanälen nur ein geringer Druck herrscht, «-durch sich der von dem starken Druck getroffene Teil des Gutes in der Stromrichtung hebt, dagegen beim Nachlassen des Druckes senkt. Hierauf wird der danebenliegende Teil des Gutes angehoben, da nunmehr die andere Serie der Kanäle unter starkem Druck stehen.As can be seen from Fig. 3, the control element advantageously consists of a shaft 6 penetrating the walls of the shaft 2 and the intermediate walls 3, on the elongated body 7, which adapt to the height of the shaft 2, are attached, the width of which is approximately the width of the channels q. correspond. The one another adjacent body 7 are each rotated by 180 ° to each other, so that when rotated of the shaft 6, the bodies 7 either open or close the channels. _ It will be like that there is always a strong pressure alternating in one series of channels, whereas there is only a slight pressure in the neighboring canals, "due to that of the the part of the goods hit by the strong pressure lifts in the direction of flow, on the other hand with Release of the pressure lowers. Then the part of the goods next to it is raised, since now the other series of channels are under heavy pressure.
Selbstverständlich kann das Steuerorgan 6, 7 auch durch Schieber o. dgl. gebildet werden.Of course, the control element 6, 7 can also be operated by slides or the like. Like. Be formed.
