Beim Lagern von Schüttgütern in Bunkern und/ oder Silos können Ausfließprobleme entstehen, die unterschiedlichste Ursachen haben und die folglich nur durch verschiedenartigste Eingriffe bzw. Verfahren gelöst werden können. So lassen sich z.B. mehlartige Schüttgüter mittels zugeführter Druckluft, wobei diese durch Anströmboden von unten her in das Häuf^ werk gelangt, fluidisieren.When storing bulk goods in bunkers and / or silos, outflow problems can arise, which have the most varied of causes and consequently only through the most varied of interventions or procedures can be solved. For example, flour-like bulk goods can be fed in using compressed air, whereby these through the inflow base from below into the heap ^ works, fluidize.
Diese Verfahrenstechnik ist für grobkörnige Materialien nicht anwendbar. Hier setzt man z.B. Geräte ein, die mehr oder minder starke mechanische Schläge in unterschiedlich langer Folge austeilen. Für jeden der genannten Schüttguttypen hat man daher inzwischen grundsätzlich unterschiedlicheThis process technology cannot be used for coarse-grained materials. Here, for example, devices are used that produce more or less strong mechanical impacts in different ways long episode. For each of the mentioned types of bulk goods, there are now fundamentally different ones
Verfahrenstechniken entwickelt, die regelmäßig dann versagen, wenn Schüttgüter mit einem breiten Kornverteilungsspektrum vorliegen.Process technologies developed that regularly fail when bulk goods with a wide Grain distribution spectrum are available.
Hier setzt der erfindungsgemäße Gedanke ein, dessen Ziel darin besteht, gerade derart inhomogen aufgebaute Schüttgutmengen betriebssicher und ohne empfindliche Anströmboden etc, fließfähig zu machen. Dieses Ziel wird dadurch erreicht/ daß die expandierend Druckluft eine Doppelfunktion ausübt, indem sie einerseits die Feingutanteile fluidisiert und andererseits das Luftzuführelement., im vorliegenden Falle ein unten offenes rohrartiges Gebilde, in Ausschlagbewegungen versetzt, die allseitig verlaufen und deren Ausschlagweite vorzugsweise durch einen mit dem Schüttgutbehälter verbundenen Bügel begrenzt wird.This is where the idea according to the invention comes into play, the aim of which is to produce such inhomogeneous structures To make bulk quantities operationally safe and without sensitive inflow plates, etc., flowable. This goal is achieved / that the expanding compressed air has a double function by on the one hand the fine material components are fluidized and, on the other hand, the air supply element, in the present case a bottom open tube-like structure, set in deflection movements that run on all sides and their deflection width is preferably limited by a bracket connected to the bulk material container.
Die Figuren 1 bis 4 sollen diese neuartige, erfindungsgemäße Technik, die sich in Laborversuchen bewährt hat, veranschaulichen.Figures 1 to 4 are intended to this novel, according to the invention Illustrate technology that has proven itself in laboratory tests.
Die Figuren zeigen ein nach unten offenes rohrartiges Element (1), das mit einem Schutz- bzw. Schüttgutabweisdach versehen ist und das mit seinen Unterkanten nicht auf der Sohle des Bunkers (3) aufliegt, sondern zu dieser einen Abstand besitzt, der durch die freie Länge der Distanzstücke (1,2) gegeben ist. Über das Rohr stück (1.3) ist das Luftzufuhr-- und -verteilungselement (1) mit dem Luftstoßgerät (4) verbunden. Je nach Einsatzfall kann das Element (1) am Ende offen oder mit einer Platte (1.4) verschlossen bzw. ver·^ sehen sein.The figures show a tube-like element (1) that is open at the bottom and is provided with a protective or bulk material deflector roof is provided and which does not rest with its lower edges on the sole of the bunker (3), but to this has a distance which is given by the free length of the spacers (1,2). About the The pipe piece (1.3) is the air supply and distribution element (1) connected to the air blast device (4). Depending on the application, the element (1) can be open at the end or closed or ver · ^ with a plate (1.4) be seen.
Die expandierende Luft entweicht seitlich aus dem Luftzufuhr"- und ^verteilungselement (1) in das Haufwerk und es wird gleichzeitig durch die expandierende Luft in schlagartige Bewegungen versetzt, die allseitig verlaufen und die nach unten durch die Bunkersohle und ansonsten durch einen Bügel (2), der z.B. fest mit der Bunkersohle verbunden ist, begrenzt werde Das Schüttgut wird also gleichzeitig verschiedenartigsten Eingriffen ausgesetzt. The expanding air escapes laterally from the air supply "- and ^ distribution element (1) in the pile and it is at the same time through the expanding Air set in abrupt movements that run on all sides and that down through the bunker sole and otherwise by a bracket (2), e.g. is firmly connected to the bunker floor, will be limited. The bulk material is therefore exposed to a wide variety of interventions at the same time.
Während staubförmige Anteile fluidisiert werden, führt das Element (1) oder eine Elementengruppe gemäß Figur 2 gleichzeitig Schläge gegen das Schüttgut aus, so daß Brückenbildungen etc. nicht auftreten können.While dusty parts are fluidized, If the element (1) or a group of elements according to FIG. 2 carries out blows against the bulk material at the same time off so that bridging etc. cannot occur.
Derartige Elemente (1) lassen sich abhängig vom Bedarf und von der Größe der Bunkersohlenfläche in beliebiger Zahl sowie in beliebiger Art und Weise anordnen. Aus der Fülle der Möglichkeiten sei auf die Figuren 2 und 3 verwiesen.Such elements (1) can be in any desired manner depending on the requirements and the size of the bunker base area Number as well as arrange in any way. From the abundance of possibilities, refer to FIGS. 2 and 3 referenced.
Hierbei stellt Figur 3 eine Lösung dar, bei der das Element (1) z.B, in die Ecke eines pyramidisch konstruierten Auslaufs verlegt worden ist, da in derartigen Bunkerbereichen stets Fließprobleme auftreten können. Figur 4 zeigt noch einmal ein grundsätzliches Ausführungsbeispiel der neuartigen, erfindungsgemäß vorgeschlagenen Vorrichtung zum Einbau in Bunker und/oder Silos.Here, Figure 3 shows a solution in which the Element (1), for example, has been placed in the corner of a pyramid-shaped spout, as in such Flow problems can always occur in bunker areas. FIG. 4 once again shows a basic exemplary embodiment the novel device proposed according to the invention for installation in bunkers and / or Silos.
