Description

Im Patent 839 329 ist ein Verfahren beschrieben, wonach der beim Sägen von Steinblöcken verwendete Stahlsand wieder in den Arbeitsgang gebracht wird, indem der Stahlsand unterhalb des Steinblockes gesammelt und von dort in einem aus Wasser und Abrieb bestehenden Schlammgemisch mitgeführt wird, welches sich im Umlauf befindet und den Stahlsand oberhalb des Steinblockes in einem Konzentrator absetzt. Hierzu wird eine Vorrichtung verwendet, die aus einem Tiefbunker zur Aufnahme des anfallenden Stahlsandes besteht, welcher unten in einen Dosierungstrichter mit Transportdüse ausläuft, der mit einem Ein- und Ablaufstutzen zum Anschluß .einer vom Konzentrator abzweigenden Überlaufleitung bzw. einer Verbindungsleitung zu einer Pumpe versehen ist, an welche eine zum Konzentrator führende Steigleitung angeschlossen ist. Dabei tritt jedoch ein starker Verschleiß in der Pumpe auf, welche das Stahlsand-Wasser-Gemisch zu befördern hat.In the patent 839 329 a method is described, after which when sawing Steel sand used by stone blocks is brought back into the operation by the steel sand is collected below the stone block and thrown into one out of water and abrasion existing sludge mixture is carried along, which is in circulation and deposits the steel sand above the stone block in a concentrator. For this a device is used, which comes from a deep bunker to receive the accumulating Steel sand, which is placed in a dosing funnel with a transport nozzle at the bottom runs out, the one with an inlet and outlet for connection .ein from the concentrator branching overflow line or a connecting line to a pump to which a riser leading to the concentrator is connected. Included however, there is severe wear and tear in the pump, which is the steel sand-water mixture has to promote.

Erfindungsgemäß wird daher vorgeschlagen, die Pumpe vor dem Tiefbunker in die lediglich das Überlaufwasser führende Leitung einzubauen und an Stelle des Dosierungstrichters mit Transportdüse einen Wasserstrahlinjektor einzubauen, mittels dessen :das Stahlsand-Wasser-Gemisch unmittelbar in den Konzentrator befördert wird. Um nur möglichst reines Wasser ohne Mitführung von etwaigen in die Überfalleitung gelangten Sand- oder Schlammkörnchen zur Pumpe gelangen zu lassen und damit die Verschleißwirkung auf ein Mindestmaß herabzudrücken, kann die vom Konzentrator zur Pumpe führende Leitung zunächst in einen Senkkasten geführt werden.According to the invention it is therefore proposed that the pump be installed in front of the underground bunker to be installed in the line that only carries the overflow water and in place of the To install a water jet injector using a dosing funnel with a transport nozzle whose: the steel sand-water mixture is conveyed directly into the concentrator. In order to only use the purest possible water without carrying any into the overflow pipe to get any sand or mud grains to the pump and thus the To reduce wear and tear to a minimum, the concentrator for The line leading to the pump must first be led into a caisson.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes wiedergegeben, und zwar zeigt Fig. I eine Ansicht der Anlage, teilweise geschnitten, Fig. 2 eine Teilzeichnung mit eingebautem Senkkasten im Schnitt.The drawing shows an embodiment of the subject matter of the invention reproduced, namely Fig. I shows a view of the system, partially in section. Fig. 2 is a partial drawing with a built-in caisson in section.

Am Auslauf des: trichterförmigen Tiefbunkers I ist ein Injektor 2 angeordnet, an :den die Steigleitung 3 zum hochliegenden Konzentrator 4 angeschlossen ist. Auf der anderen Seite ist unter Zwischenschaltung eines Sperr- bzw. Regulierelements 5 eine Pumpe 6 angeschlossen, in welche das vom Konzentrator ausgehende Überlaufrohr 7 einmündet. Zur Steigerung des Reinheitsgrades des der Pumpe durch das Überlaufrohr zuzuführenden Wassers kann die Anordnung auch so getroffen werden, daß das Überlaufrohr 7 zunächst in einen Senkkasten geführt wird, der zweckmäßigerweise durch eine Zwischenwand 8 in zwei Kammern 9, Io unterteilt ist. Dadurch wird erreicht, daß sich die Hauptmasse mitgeführter Verunreinigungen: in der Kammer 9, in welche das Überfallrohr mündet, absetzt, so daß die andere Kammer Io, die mit der Pumpe durch ein Verbindungsrohr II verbunden ist, praktisch vollgereinigtes Wasser enthält.At the outlet of the funnel-shaped underground bunker I is an injector 2 arranged, to: which the riser 3 is connected to the overhead concentrator 4 is. On the other hand, a blocking or regulating element is interposed 5, a pump 6 is connected, into which the overflow pipe emanating from the concentrator 7 joins. To increase the purity of the pump through the overflow pipe to be supplied water, the arrangement can also be made so that the overflow pipe 7 is first led into a caisson, which is expediently through a partition 8 is divided into two chambers 9, Io. This ensures that the main mass entrained impurities: in the chamber 9, into which the overflow pipe opens, settles so that the other chamber Io, which is connected to the pump by a connecting pipe II is connected, contains practically fully purified water.
