Die Erfindung l>etrirrt einen Bunker für <lie Aufnahme und Entnahme von Schüttgut verschiedener Korngröße, der sich von den bisher gebräuchlichen Bunkern dieser Art dadurch unterscheidet, daß er in seinem Innern wabenartig ausgebildet ist, um l>eim Einfüllen und Abziehen des Gutes eine selbsttätige Entmischung desselben in verschiedenartige Körnung zu verhindern.The invention found a bunker for admission and removal of bulk material of various grain sizes that differ from those previously used Bunkers of this type differ in that they are honeycombed inside to l> When the goods are filled in and withdrawn, they automatically separate into different types To prevent grit.

Bunker bisher üblicher normaler Bauart für die Aufnahme von Schüttgut, insbesondere wenn sie kontinuierlich gefüllt werden, neigen dazu, daß das Füllgut, wenn es unterschiedlich in seiner Korngröße ist, sich durch die Bildung eines Schüttkegels bei seiner Einfüllung in den Bunker in seiner Korngröße entmischt. Dabei bleibt das feine Korn überwiegend in der Mitte des Schüttkegels, während das gröliere und grobe Korn den Rändern des Bunkers zurieselt. Die umgekehrte Erscheinung tritt bei der Entnahme des Gutes aus dem Bunker ein, indem zunächst die mittleren feinkörnigen Bestandteile des Gutes und zum Schluß die grobkörnigen Bestandteile dem Bunkerauslauf zufließen. Diese sich bildende Entmischung tritt naturgemäß je nach der Beschaffenheit des Gutes beim Abziehen des Bunkers in allen nur möglichen Zwischenveränderungen auf. Sie ist in allen Industrien, die mit festliegenden Korngrößengemisehen arbeiten müssen, wol>ei die jeweilige Korngrößenzusammensetzung fur die Gute des Erzeugnisses einen bestimmenden Einfluß hat, beispielsweise in der keramischen Industrie, recht unangenehm und nachteilig. Da aber bei rationeller Wirtschaftsführung auf eine vorübergehende Lagerung des Gutes im Bunker in der Regel nicht verzichtet werden kann, ist es von großer wirtschaft-Bunker of the normal design for the reception of bulk goods, especially if they are continuously filled, tend to the filling material, if it differs in its grain size is due to the formation of a cone of material when it is filled into the bunker in its grain size segregated. The fine grain remains predominantly in the center of the cone of material, while the coarse and coarse grain trickled down the edges of the bunker. The reverse phenomenon occurs with the Removal of the goods from the bunker by first adding the medium fine-grained components of the goods and finally the coarse-grained components flow into the bunker outlet. This yourself Formative segregation occurs naturally, depending on the nature of the goods, when the bunker is removed in all possible interim changes. It is fixed in all industries with Grain size mixed have to work if they want the respective grain size composition has a determining influence on the quality of the product, for example in the ceramics industry, quite unpleasant and disadvantageous. But there with more rational Management generally does not dispense with temporary storage of the goods in the bunker can be, it is of great economic

Claims

rather the importance of creating a bunker, inside of which a reversal to remedy the aforementioned Disadvantage of the previous bunker is met.

The invention now relates to a bunker for receiving and removing bulk goods of various types Grain size at which in the simplest and most surprising way and with the simplest means the aforementioned disadvantage associated with the previous bunkers is avoided. To this end shows the bunker, which does not differ in its exterior from the previous bunker tours inside a honeycomb-like structure, which by the arrangement of vertical, intersecting, is formed at a certain distance from each other held walls. These walls don't go up down onto the outer bunker walls, but remain at a certain distance from them, so that the honeycomb formed by the walls freely downwards when the goods are removed can leak. The upper part of the individual honeycombs is different in height and such designed so that the honeycomb, into which the grain size mixture initially enters when filling, is the highest and the neighboring honeycombs then according to the respective angle of repose of the goods are lower and so on.

In the drawing, the bunker according to the invention is illustrated schematically in an exemplary embodiment, 1 and 2 show the bunker in two different side views, while Fig. 3 shows the same in plan view.

With ι the hopper filling opening is referred to, and 2 is the outlet opening of the bunker, to which all bunker walls run. According to the invention has The interior of the bunker runs vertically and is kept at a certain distance from each other Walls 3 and at right angles to these walls 4. Both walls 3 and 4 are not enough up to the bottom of the bunker, but have a certain distance from this, so that the through the intersecting walls 3 and 4 formed honeycombs 5 run down and the contents of the bunker outlet 2 can run. 6 with the filler pipe is referred to, through which the mixture in the bunker the longest honeycomb is fed.

The distance between the individual walls and thus the size of the honeycomb is in their Cross-section expediently as small as possible, but dimensioned so large that the sticking In no case are goods to be stored on the vertical walls of the honeycomb occurs or the material can be shaken freely with safety by vibrating devices.

When the goods are filled into the bunker, the filling process proceeds in such a way that initially the highest Honeycomb is filled until a slip cone forms on the highest point of the honeycomb, where the another good in its fine-grained and coarse-grained mixture slips down and the neighboring ones Honeycomb fills. This filling process is repeated until all the honeycombs are completely filled. By the arrangement the honeycomb inside the bunker achieves a slight segregation within the walls of the good cannot be avoided, which is all the more meaningless the smaller it is Honeycomb cross-section is kept. When removing the bunker, there is now the advantage that the draining material flows into the bunker outlet with practically the same grain size composition, in which it was filled, as the interior of the bunker is subdivided into honeycombs. and coarse grain remains practically evenly distributed over the entire cross-section of the bunker, if one disregards the slight, negligible segregation in the individual honeycombs.
