Abstract
Description
Die Erfindung betrifft ein Silo für Schüttgut entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a silo for bulk material according to the preamble of claim 1.
Ein Schüttgutsilo entsprechend dem Oberbegriff des Anspruches 1 ist beispielsweise durch die AT-C-303 625 bekannt. Die an die zentrale Abzugskammer angeschlossene Entlüftungseinrichtung wird hierbei durch eine von der Spitze der kegelförmigen Abzugskammer zentral durch den Innenraum des Silos zur Silodecke geführte Rohrleitung gebildet.A bulk goods silo according to the preamble of claim 1 is known for example from AT-C-303 625. The venting device connected to the central extraction chamber is formed here by a pipeline which runs from the tip of the conical extraction chamber centrally through the interior of the silo to the silo ceiling.
Nachteilig ist bei einer derartigen Ausführung die erhebliche mechanische Beanspruchung, der diese Entlüftungsleitung durch das Gut im Silo ausgesetzt ist.A disadvantage of such a design is the considerable mechanical stress to which this ventilation line is exposed through the material in the silo.
Zum Stand der Technik gehören weiterhin Silos (DE-B-25 39 753 und DE-A-27 27 499), bei denen der Austrag des Gutes aus der zentralen Abzugskammer über eine radial von der Abzugskammer zur Umfangswand des Silos führende Entleerungskammer erfolgt, über die zugleich die Entlüftung der Abzugskammer vorgenommen wird. Von dieser Entleerungskammer führt an der Umfangswand des Silos eine Entlüftungsleitung zu einer Entstaubungseinrichtung oder zum oberen Teil des Siloinnenraumes. Nachteilig ist bei einer derartigen Ausführung, daß eine solche, gegen den Innenraum des Silos abgeschlossene Entleerungs- und Entlüftungskammer erheblich die Geometrie des Silos stört und ein über den gesamten Umfang gleichmäßiges Zuströmen des Gutes aus dem Siloinnenraum in die zentrale Abzugskammer beeinträchtigt.The prior art also includes silos (DE-B-25 39 753 and DE-A-27 27 499), in which the material is discharged from the central discharge chamber via a discharge chamber leading radially from the discharge chamber to the peripheral wall of the silo which is also the ventilation of the trigger chamber. From this emptying chamber, a ventilation line leads to a dedusting device or to the upper part of the interior of the silo on the peripheral wall of the silo. The disadvantage of such a design that such, against the interior of the The emptying and venting chamber, which is closed off from the silo, significantly disrupts the geometry of the silo and impairs a uniform flow of the goods over the entire circumference from the interior of the silo into the central extraction chamber.
Der Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung dieser Nachteile der bekannten Ausführungen ein Silo entsprechend dem Oberbegriff des Anspruches 1 so auszubilden, daß trotz einfacher Bauweise und Vermeidung unerwünschter mechanischer Beanspruchungen der Entlüftungseinrichtung ein allseitig über den gesamten Umfang gleichmäßiges Zuströmen des Gutes aus dem Siloinnenraum zur zentralen Abzugskammer gewährleistet ist.The invention is therefore based on the object, avoiding these disadvantages of the known designs, a silo according to the preamble of claim 1 so that despite simple construction and avoidance of undesirable mechanical stresses of the ventilation device, a uniform flow over the entire circumference of the material from the silo interior to the central deduction chamber is guaranteed.
Diese Aufgabe wird erfindungsgemäß durch das kennzeichnende Merkmal des Anspruches 1 gelöst. Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the characterizing feature of claim 1. Appropriate embodiments of the invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Silo enthält die Entlüftungseinrichtung einen an sich bekannten, von der Abzugskammer zur Umfangswand des Silos führenden, an eine Entlüftungsleitung angeschlossenen Entlüftungskanal. Erfindungsgemäß weisen die Seitenwände dieses Entlüftungskanales Öffnungen auf, durch die Gut aus dem Siloinnenraum dem Entlüftungskanal und durch diesen der zentralen Ab zugskammer zuströmt. Der Entlüftungskanal ermöglicht damit zugleich einen Guttransport zur zentralen Abzugskammer und gewährleistet auf diese Weise eine gleichmäßige, rotationssymmetrische Beschickung der zentralen Abzugskammer.In the silo according to the invention, the ventilation device contains a ventilation channel which is known per se and leads from the discharge chamber to the peripheral wall of the silo and is connected to a ventilation line. According to the invention, the side walls of this ventilation duct have openings through which the material from the silo interior space the ventilation duct and through this the central outlet tensile chamber flows in. The venting channel thus also enables good transport to the central discharge chamber and in this way ensures uniform, rotationally symmetrical loading of the central discharge chamber.
