Description

Luftsetzmaschine zum Trennen von Kohlen und sonstigen Mineralien mit einer Gruppe von mehreren Pulskörpern BeiLuftherden zurAufbereitung von Erzen, Kohlen oder sonstigem Gut ist es bekannt, in die Leitung für den Luftstrom, der unter das stillstehende Setzbett geblasen wird, eine Pulskörpergruppe mit einer Reihe von beweglichen Pulskörpern anzuordnen. Gegenstand der Erfindung ist die Verbesserung derartiger Vorrichtungen, indem die Pulskörpergruppe unterhalb der Herdfläche und parallel zu dieser angeordnet wird. Dadurch ergibt sich der Vorteil, daß der Luftstrom auf die ganze Herdfläche gleichmäßig einwirkt, ferner vermeidet diese Anordnung die bei bekannten Bauarten auftretenden Wirbelverluste, da die von dem Pulskörper zu der Herdfläche gehenden Stromlinien alle .dieselbe Länge haben und auf der kurzen Strecke zwischen Pulskörpergruppe und Herdfläche so gut wie keine schädliche Wirbelbildung auftreten kann.Air jig for separating coals and other minerals with a group of several pulse bodies in air stoves for the preparation of ores, coal or other good it is known to be in the duct for the air flow that flows under the stationary bed is blown, a pulse body group with a number of to arrange movable pulse bodies. The object of the invention is the improvement such devices by placing the pulse body group below the hearth surface and is arranged parallel to this. This has the advantage that the air flow acts evenly on the entire stove surface, also avoids this arrangement the eddy losses occurring in known designs, since those from the pulse body Streamlines going to the hearth are all of the same length and on the short one Distance between the pulse body group and the focal area, as good as no harmful vortex formation can occur.

Die Erfindung ist in.einem Ausführungsbeispiel in der Zeichnung dargestellt.The invention is shown in an exemplary embodiment in the drawing.

Der Ventilator v erzeugt Druckluft, die er durch die Leitung d in Richtung des Pfeiles zu der Pulskörpergruppe b hinbläst. Diese Pulskörpergruppe besteht aus einzelnen umlaufenden Gruppen, die parallel zueinander angeordnet sind und auch parallel zueinander laufen. Sie werden von dem Motor b1 aus über ein Kettenglied o. dgl. b= alle gleichzeitig und gleichmäßig angetrieben. In diesem Pulsventil wird der vom Ventilator erzeugte stetige Luftstrom in einen pulsenden l.uttstrom verwandelt, und dieser wird unmittelbar zu der Herdfläche c geleitet, auf welcher sich das zu setzende Gut befindet. Dieses Gut wird von einem Trichtert her regelbar aufgegeben, durch die Luftströnle getrennt, z. B. in Kohle und Berge, worauf dann nach Scheidung an dem Stauwehrs clie Kohle über die Schurre u und die Berge vermittels der Austragwalze w ausgetragen werden.The fan v generates compressed air, which it passes through the line d in Blows in the direction of the arrow towards the pulse body group b. This pulse body group consists of individual revolving groups that are arranged parallel to one another and also run parallel to each other. They are made from the motor b1 via a chain link or the like. b = all driven simultaneously and evenly. In this pulse valve is the constant air flow generated by the fan is transformed into a pulsating air flow, and this is passed directly to the hearth surface c on which the to settling good is located. This good is fed in a controllable way from a funnel, separated by the air streams, e.g. B. in coal and mountains, what then after divorce At the weir the coal over the chute and the mountains by means of the discharge roller w to be carried out.

Die Pulskörper müssen nicht als umlaufende Klappen ausgebildet sein, können vielmehr auch schwingend angeordnet werden. Unter besonderen Betriebsverhältnissen können die einzelnen Pulskörper zueinander einstellbar gemacht werden, so daß ein Pulskörper dem anderen voreilt oder ihm gegenüber zurückbleibt.The pulse bodies do not have to be designed as circumferential flaps, rather, they can also be arranged to oscillate. Under special operating conditions the individual pulse bodies can be made adjustable to one another, so that a Pulse body leads or lags behind the other.

Ferner ist es möglich, die Pulskörper so anzuordnen, @daß sie ständig einen Teil des vom Ventilator kommenden Luftstromes frei durchlassen, so daß also auf das Setzbett sowohl ein stetiger als auch ein pulsender Luftstrom einwirken.It is also possible to arrange the pulse bodies so that they are constantly let some of the air flow from the fan freely pass through, so that Both a steady and a pulsating flow of air act on the bed.
