Description

Die Erfindung betrifft eine Vorrichtung zum Beschicken von Schachtöfen, insbesondere Hochöfen, die ein gleichmäßiges Verteilen des Beschickungsgutes über den gesamten Ofenquerschnitt ermöglicht, was bekanntlich zur Erzielung eines einwandfreien Ganges des Schachtofens von entscheidendem Einfluß ist. Es ist bereits eine ganze Reihe von Verteilungsvorrichtungen in den verschiedensten Ausführungen bekanntgeworden. So ist u. a. auch der Einbau trichterförmiger Verteilereinsätze, ferner die Verwendung von Kegelglocken vorgeschlagen worden. Bei derartigen Verteilereinrichtungen erfolgt die Verteilung des Beschickungsgutes auf einer oder mehreren Kreisringflächen, was somit eine ungleichmäßige Ofenbeschickung ergibt, die, wie gesagt, unerwünscht ist. Zwecks Vermeidung dieses Nachteiles ist eine Verteilervorrichtung mit drehender Gichtbühne und einem ebenfalls drehbaren, exzentrisch zur Ofenachse angeordneten Verteiler vorgeschlagen worden, dessen Mündung zur gleichmäßigen Verteilung des Gutes in Kurven über den Schachtofen geführt wird. Diese Einrichtung ermöglicht zwar eine nahezu gleichmäßige Verteilung des Möllergutes über den ganzen,Ofenquerschnitt, jedoch ist der Aufbau dieser Verteilervorrichtung recht umständlich und kostspielig.The invention relates to a device for loading shaft furnaces, in particular blast furnaces that allow the load to be evenly distributed allows the entire furnace cross-section, which is known to achieve a flawless Ganges of the shaft furnace is of decisive influence. It's already a whole Series of distribution devices in various designs become known. So is i.a. also the installation of funnel-shaped distributor inserts, furthermore the use suggested by cone bells. In such distribution devices takes place the distribution of the load on one or more circular ring surfaces, what thus results in an uneven furnace loading, which, as said, is undesirable. To avoid this disadvantage, a distributor device with rotating Blast furnace and a rotatable, eccentric to the furnace axis Distributor has been proposed whose mouth for the even distribution of the Good things are guided in curves over the shaft furnace. This facility enables an almost even distribution of the Möllergood over the entire furnace cross-section, however, the construction of this distribution device is quite cumbersome and expensive.

Die Erfindung schafft demgegenüber eine wesentlich vereinfachte Verteilervorrichtung mit ebenfalls drehbarer Gichtbühne, die eine vollkommen einwandfreie, gleichmäßige Ofenbeschickung ermöglicht. Das erfinderisch Neue besteht darin, daß die Aufgabevorrichtung; zweckmäßig in Form eines oberhalb der Gichtbühne zentral angeordneten Auffangtrichters, mit einem dreh- oder schwenkbaren Auslauf versehen ist.In contrast, the invention creates a significantly simplified distribution device also with a rotating furnace platform, which ensures a perfectly flawless, even Furnace loading enabled. The inventive novelty is that the feeding device; expediently in the form of a collecting funnel centrally arranged above the furnace platform, is provided with a rotatable or swiveling spout.

In der Zeichnung ist ein Ausführungsbeispiel einer solchen Beschickungsvorrichtung im Aufriß rein schematisch dargestellt.In the drawing is an embodiment of such a loading device shown purely schematically in elevation.

Die Beschickungsvorrichtung ist auf einem Schacht z aufgebaut. Der obere dichte Ofenabschlüß erfolgt durch die drehbar angeordneteGichtbühne2. Auf der Gichtbühne z ist der Aufgabetrichter 3 mit einem Rohransatz 3' in der Ofenachse befestigt. Am unteren Ende des Rohransatzes 3' ist ein zweckmäßig rohrförmiger Auslauf q. derart angelenkt, daß dieser als Verteiler über den ganzen Ofenquerschnitt zwecks Erzielung einer gleichmäßigen Verteilung des Beschickungsgutes verschwenkbar ist.The loading device is built on a shaft z. Of the The upper, tight furnace closure is achieved by the rotatable light platform 2. on the top stage z is the feed hopper 3 with a pipe extension 3 'in the furnace axis attached. At the lower end of the pipe extension 3 'is an expedient tubular outlet q. hinged in such a way that this serves as a distributor over the entire furnace cross-section Achieving a uniform distribution of the load is pivotable.

PATENTANSPRUCH: Verteilungsvorrichtung für die Beschickung von, Schachtöfen, insbesondere Hochöfen, mit einer zum Abschluß des Schachtes dienenden drehbaren Gichtbühne und mit einem ebenfalls drehbaren, unterhalb der Gichtbühne angeordneten Verteiler, dem .das Beschickungsgut durch einen oberhalb der Gichtbühne angeordneten Trichter zugebracht wird, dadurch gekennzeichnet, daß der Verteiler (q.) derart schwenkbar am Trichter (3, 3') angebracht ist, daß das Beschickungsgut gleichmäßig über den Schachtquerschnitt verteilt wird. PATENT CLAIM: Distribution device for charging shaft furnaces, in particular blast furnaces, with a rotatable furnace platform serving to close the shaft and with a distributor that is also rotatable below the furnace platform and to which the feed material is fed through a funnel arranged above the furnace platform that the distributor (q.) is attached to the funnel (3, 3 ') so that it can pivot in such a way that the load is distributed evenly over the shaft cross-section.
