Description

Vorrichtung zum Schwelen von Kohlen, Schiefer oder anderen bitumenhaltigen Stoffen mit einer innen beheizten Förderschnecke für das Gut. Bei dem Schwelen von Kohlen (Halbverkokung), Schiefer und anderen bituinenhaltigen Stoffen, die in einer Retorte o. dgl. durch eine innen beheizte Schnecke weitergeleitet «erden, würde das Anbacken des Schwelgutes an den Wandungen der Förderschnecke bald dazu führen, daß das Gut anstatt in der Retorte weiter zu wandern, an den Wandungen der Förderschnecke haften bleibt, und es würde dann die Förderschnecke wirkungslos umlaufen, also der ganze Schwelvorgang beeinträchtigt werden. ' Lm diesem Übelstand mit Sicherheit vorzubeugen. ist erfindungsgemäß in der oberhalb der Förderschnecke vorgesehenen, als Sammelraum für die sich bildenden gas- oder dampfförmigen Destillationserzeugnisse dienenden Kammer eine Abstreichvorrichtung angebracht, die sich aus in der Längsrichtung der Schnecke nebeneinanderliegenden unabhängig voneinander auf und nieder beweglichen Abstreichbrettern derart zusammensetzt, daß diese selbsttätig abstreichend mit allen Teilen der Schneckenwandung zusammenwirken.Device for smoldering coal, slate or other bituminous Fabrics with an internally heated screw conveyor for the goods. With the smoldering of Coals (semi-coking), slate and other bituminous substances in a Retort or the like forwarded through an internally heated screw the caking of the smoldering material on the walls of the screw conveyor will soon lead to that the material instead of moving further in the retort, on the walls of the screw conveyor remains sticking, and the screw conveyor would then rotate ineffectively, i.e. the whole smoldering process will be impaired. Certainly in this evil situation to prevent. is according to the invention in the provided above the screw conveyor, as a collecting space for the gaseous or vaporous distillation products that are formed Serving chamber attached a scraper, extending out in the longitudinal direction the worm, which are adjacent to each other, can be moved up and down independently of each other Skirting boards assembled in such a way that they automatically skimmed off with all Parts of the screw wall cooperate.

Die Zeichnung veranschaulicht diese Sonclerausführung des Abstreichers, wobei Abb. i einen senkrechten Längsschnitt durch einen Teil der Retorte, Abb. z einen Querschnitt geben.The drawing illustrates this Soncler version of the scraper, where Fig. i is a vertical longitudinal section through part of the retort, Fig give a cross section.

a bezeichnet die Doppelwandung des die Förderschnecke d aufnehmenden Troges, der die Außenbeheizung der Kohle vermittelt. Der Durchmesser der Förderschnecke ist gegenüber den üblichen Förderschnecken derart vergrößert, daß eine Trommel entsteht und somit das Gut in einer Schichthöhe von nur wenigen Zentimetern zwischen den entsprechend niedrig gehaltenen Gängen dl der Schnecke weiter wandert. Oberhalb der Schnecke d und in der den gas- oder dampfförmigen Destillationserzeub nissen als Sammelraum dienenden Kammer o sind in der Längsrichtung der Schnecke nebeneinanderliegende Abstreichbretter k unabhängig voneinander auf und nieder beweglich gelagert, wobei zur richtigen Führung dieser Abstreichbretter quer zur Längsachse der Schnecke verlaufende Leisten v und ferner seitliche Führungswandungen u, vorgesehen sein können.a denotes the double wall of the screw conveyor d receiving it Trough, which mediates the external heating of the coal. The diameter of the screw conveyor is so enlarged compared to the usual screw conveyors that a drum is created and thus the goods in a layer height of only a few centimeters between the Correspondingly low threads dl of the snail continues to migrate. Above the screw d and in the gaseous or vaporous distillation products Chamber o serving as a collecting space are adjacent to one another in the longitudinal direction of the screw Skirting boards k mounted movably up and down independently of one another, wherein for the correct guidance of these skimming boards running transversely to the longitudinal axis of the screw Bars v and also lateral guide walls u can be provided.

Wie ersichtlich, werden die einzelnen Abstreichbretter beim Durchgang eines Schneckengangs allmählich gehoben und zufolge ihres Eigengewichts wieder gesenkt, auf diese Weise mit sämtlichen Wandungen der Förderschnecke nach Art von Schabern zusammenwirkend.As can be seen, the individual skimming boards are in the passage gradually raised by a snail's passage and lowered again due to their own weight, in this way with all the walls of the screw conveyor in the manner of scrapers cooperating.

Die einzelnen Abstreichbretter brauchen nicht über die ganze Länge der Retorte sich zu erstrecken; vielmehr genügt es, sie auf etwa einem Drittel oder der Hälfte der Trommel von der Eintrittsseite des Gutes her vorzusehen.The individual skimming boards do not need over the entire length the retort to extend; rather, it is sufficient to reduce it to about a third or half of the drum from the entry side of the goods.
