Description
Vorrichtung zur Verhinderung der Fortpflanzung von Grubenexplosionen mittels Gesteinstaubverwirbelung. Das Hauptpatent hat eine Vorrichtung zum !3egenstand, die darin besteht, daß durch die der Explosion vorlaufende Luftwelle der Boden eines Staubkastens stützlos gemacht wird, so daß er mit dem Staub in die Strecke einfällt. Da es nun aber notwendig ist, den Staub möglichst dicht gegen die Atmosphäre abzuschließen, damit er vor Feuchtigkeit geschützt ist, so ist es zweckmäßig, den hasten auch mit einem Deckel zu versehen. Ein solcher aber bildet, wenn er am Kasten befestigt ist, ein Hindernis für den schnellen Absturz des Staubes, weil der Staub an ihm haftet und vor allen Dingen, weil es am Nachtritt der Luft fehlt.Device for preventing the propagation of mine explosions by means of rock dust turbulence. The main patent has a device for the subject which consists in the fact that the ground of a Dust box is made supportless, so that it falls with the dust in the track. But since it is now necessary to seal off the dust as tightly as possible from the atmosphere, So that it is protected from moisture, it is advisable to hurry along with you to provide a lid. But if it is attached to the box, it forms an obstacle to the dust's rapid fall because the dust adheres to it and above all, because there is no air afterwards.
Es ist aber auch nicht zweckmäßig, den Staub etwa dadurch abzudecken, daß man einen losen Deckel verwendet, der vom Staub selbst getragen wird, und zwar erstens, weil dadurch der Staub belastet wird, so daß er im Laufe der Zeit durch das dauernd wirkende Deckelgewicht zusammenklumpt, und zweitens, weil keine gute Gewähr für die richtige Lage des Deckels besteht, die infolge der Erzveiterung des Kastens nach unten, die nicht entbehrt werden kann, nur dann gegeben ist, wenn der Deckel genau in Höhe des oberen Kastenrandes liegt. Aus diesem Grunde trägt der Erfindung gemäß der Kastenboden Stützen, auf welchen der Deckel auflagert.However, it is also not advisable to cover the dust by, for example, using a loose lid supported by the dust itself, namely first, because it pollutes the dust, so that it will pass through over time the permanent weight of the lid clumps together, and secondly because it is not a good one There is a guarantee that the cover is in the correct position, as a result of the expansion of the Downward box, which cannot be dispensed with, is only given when the Lid is exactly at the level of the upper edge of the box. For this reason, the Invention according to the box bottom supports on which the lid rests.
In der Zeichnung ist die Erfindung in zwei Figuren dargestellt, und zwar in einem Quer-und einem Längsschnitt.In the drawing, the invention is shown in two figures, and although in a transverse and a longitudinal section.
Der von einem Traggerüst getragene Staubkasten a besitzt einen Boden h, der dem Hauptpatent gemäß durch die Fahne c gestützt wird. Dieser Boden trägt Stützen d, die durch den Kasten hindurchreichen und die den Deckel e mindestens an den vier Ecken unterstützen.The dust box a carried by a supporting structure has a floor h, which is supported by flag c according to the main patent. This floor carries Supports d, which extend through the box and which the lid e at least support at the four corners.
MTird die Vorrichtung im Explosionsfalle ausgelöst, so stürzt gleichzeitig mit dem Boden b und dem von ihm getragenen Staub auch der Deckel e mitsamt den Stützen d in die Strecke ein.If the device is triggered in the event of an explosion, then at the same time as the floor b and the dust it carries, the cover e together with the supports d collapses into the track.
