Description

Beschickungsvorrichtung für Umwälzöfen Es ist bekannt, ein leicht transportable Rohr, in welches ein Tragblech eingeschoben ist, mit den zu härtenden Teilen in den Glühofen zu schieben und aus dem Ofen zum Abschreckbad zu befördern, dort zu entleeren und die ganze Vorrichtung leer wieder in den Ofen zurückzuschieben. Des weiteren sind Trockenvorrichtungen bekannt, bei denen schubladenförmige Horden- benutzt «-erden.. Derartige Vorrichtungen sind zum Veredeln von Leichtmetallgegenständen in Umwälzöfen ungeeignet. Es ist ferner bekannt, Beschickungsvorrichtungen zum Einschieben oder Einfahren in den Nutzraum von Industrieöfen in Kastenform zu benutzen. Hierbei muß zum Ein- und Ausfahren die Ofentür geöffnet werden, «-as mit Zeit- und Wärmeverlusten verbunden ist. Insbesondere entstehen durch Eintritt von Kaltluft durch die geöffnete Tür erhebliche Wärmeverluste. Diese Übelstände lassen sich durch die nachstehend beschriebene Vorrichtung beseitigen.Loading device for circulating ovens It is known to be a light transportable pipe, into which a support plate is inserted, with the to be hardened Pushing parts into the annealing furnace and conveying them out of the furnace to the quenching bath, there to empty and the whole device to be pushed back empty into the oven. Furthermore, drying devices are known in which drawer-shaped tray used «-erden .. Such devices are for refining light metal objects unsuitable in circulating ovens. It is also known, loading devices for insertion or to use entry into the usable space of industrial ovens in box shape. Here the oven door must be opened to move it in and out, "- with loss of time and heat connected is. In particular, cold air enters through the open Significant heat losses in the door. These evils can be broken down by the below eliminate the device described.

Die Abbildung zeigt eine beispielsweise Ausführung einer Beschickungsvorrichtung für horizontale Kammeröfen. Der oben offene schubladenförmige Beschickungsbehälter i, der zur Aufnahme des Glühgutes dient, ist mit einem wärmeisolierten Verschlußstein -, der den Ofenhals in eingefahrenem Zustand ausfüllt, und einer Ofentür 3 fest verbunden. Die ganze Anordnung ist durch Rollen d. und 5 fahrbar auf Schienen 6, die außerhalb des Ofens vorgesehen sind, und auf Schienen 7, die im Innern des Ofens liegen. Die Rückwand 8 des Beschickungsbehälters i hat genau den Ouerschnitt der Türöffnung, so daß letztere bei ausgefahrenem Beschickungsbehälter die Ofenöffnung verschließt. Der Boden 9 des Beschickungsbehälters ist abklappbar oder um eine der Mittelachsen kippbar angeordnet.The figure shows an example of an embodiment of a loading device for horizontal chamber furnaces. The drawer-shaped loading container open at the top i, which is used to receive the annealing material, is equipped with a thermally insulated locking stone -, which fills the oven neck in the retracted state, and an oven door 3 firmly tied together. The whole arrangement is by rolling d. and 5 mobile on rails 6, provided outside the furnace and on rails 7 placed inside the furnace lie. The rear wall 8 of the loading container i has exactly the Ou section of the Door opening so that the latter opens the furnace when the loading container is extended locks. The bottom 9 of the loading container can be folded down or around one of the Center axes tiltable.

Gemäß der Erfindung dient der wärmeisolierte Verschlußstein gleichzeitig als Türverschluß. Dadurch ist es möglich, durch einen Handgriff die Türöffnung des Ofens freizulegen und gleichzeitig den Beschickungsbehälter herauszuziehen. Im ausgefahrenen Zustand steht die Rückwand der Schublade in der Türöffnung und schützt somit das Ofeninnere vor direktem Eintritt von Kaltluft.According to the invention, the thermally insulated locking stone is used at the same time as a door lock. This makes it possible to open the door of the Uncover the furnace and at the same time pull out the loading container. Im extended State, the back wall of the drawer is in the door opening and thus protects the Inside of the furnace in front of the direct entry of cold air.
