"Spritzdüse zum Einbringen von trocken angemischten Konsolidierungs- bzw. Dammbaustoffen, vorzugsweise im untertägigen Bergbau"."Spray nozzle for the introduction of dry-mixed consolidation or dam building materials, preferably in underground mining ".

Es ist bekannt, z.B. Konsolidierungsmassen im Bergbau für das angrenzende Gebirge aus Gips, Kraftwerkfilterasche, Zement und aus ähnlichen Stoffen herzustellen.It is known, e.g. consolidation masses in mining for the adjacent mountains made of gypsum, Power plant filter ash, cement and the like To manufacture fabrics.

Diese trocken angemischten Stoffe werden mittels Druckluftfördereinrichtung über Rohrleitungen oder Förderschläuche bis zum Verwendungsort transportiert,These dry mixed substances are conveyed by compressed air via pipes or Conveying hoses transported to the place of use,

Die Streckenlängen sind sehr unterschiedlich.The route lengths are very different.

Am Ende der pneumatischen Förderstrecke steht in derAt the end of the pneumatic conveyor line, the

Regel ein flexibler Austragschlauch, der mit einer Spritzdüse, in die Wasser eingeführt wird, am letzten Austragstück verbunden ist, wodurch das auszutragende Gemisch init Wasser benetzt wird und somitUsually a flexible discharge hose connected to a spray nozzle into which water is introduced Discharge piece is connected, whereby the mixture to be discharged is wetted with water and thus

a) für den Bedienungsmann und die angrenzenden dort tätigen Arbeiter keine Staubbelästigung und Staublungengefahr bedeutet unda) No dust nuisance or risk of dust lungs for the operator and the adjacent workers means and

b) die notwendige Abbinde-Feuchte der Konsolidierungsmasse oder dem Dammbaustoff zugeführt wird. b) the necessary setting moisture is supplied to the consolidation compound or the dam building material.

Diese Spritzförderdüsen, die aus einer Mischstrecke und meistens einem Wasserzuführungsring bestehen, sind nicht optimiert, d.h. entweder ist die Wasserte ng e so gro£, daß es nicht staubt, aber andererseits das Abbindeverhalten der einzusetzenden Konsolidierungsbaustoffe durch die zu hohe leuchte verzögert wird, oder aber die Wassermenge ist zu gering, und es entsteht Staub.These spray conveyor nozzles that come from a mixing section and mostly a water supply ring are not optimized, i.e. either the water value It is so large that there is no dust, but on the other hand the setting behavior of the consolidation building materials to be used is delayed by the too high light, or the amount of water is too low, and dust is created.

Um hier ein optimales Austrittsdüsensystem anzuwenden,In order to use an optimal outlet nozzle system here,

wird erfindungsgemäß "befunden, daß für die Länge der Austrittsstrecke zwischen Wassereinführung und Austritt des Materials, das mit dem Wasser vermischt werden muß, eine Spritzdüsenlänge zu wählen ist, die etwa 12-15 mal langer ist als der Eaterialzuführunpsschlauch, der zur Spritzdüse führt, und die Wassereinführung nicht unter 20 bar Druck am Beginn der Düsenstrecke zugeführt werden muß, wodurch gewährleistet ist, daß z.B. bei einem 35 nun lichte Weite Materialzuführungsschlauch eine Spritzdüsenlänge gewählt werden muß, die in etwa bei 500 mm liegt, und die Wasserzuführung zu dem pneumatisch geförderten Material - zugegeben durch einen Wasserringoder eine im Materialstrom angeordnete Wasserzuführungsdüse - am Beginn der Spritzdüse mit z.B. 25 bar vorgenommen wird, wobei erreicht wird, daß die Staubbindung so gering ist, daß keine Belästigung der Arbeiter im Umgebungsbereich stattfindet und eine wunschgerechte Feststoff-Wasser-Gemischanreicherung erzielt wird.According to the invention "found that for the length of the Outlet section between the water inlet and outlet of the material that has to be mixed with the water, Choose a spray nozzle length that is about 12-15 times is longer than the material feed tube that is used for the Spray nozzle leads, and the water inlet is not supplied under 20 bar pressure at the beginning of the nozzle section must, which ensures that, for example, with a 35 now clear width of the material feed hose a Spray nozzle length must be selected, which is approximately 500 mm, and the water supply to the pneumatic conveyed material - added through a water ring or a water supply nozzle arranged in the material flow - at the beginning of the spray nozzle with e.g. 25 bar is achieved, the dust binding is so low that no nuisance to workers in the Surrounding area takes place and a desired solids-water mixture enrichment is achieved.

In der beiliegenden Zeichnung ist die erfindungsgemäßeIn the accompanying drawing is the inventive

mit (4) die Wasserzuführung.with (4) the water supply.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte und beschriebene Ausführungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Jjpritzdüseneinrichtung zum Benetzen von Material zu verwenden, das aus Gips, Zement, Filterasche und ähnlichen Baustoffen besteht, vorzugsweise zur "Verwendung als Streckenkonsolidierungsmaterial oder als Dammbaustoffe im untertägigen Bergbau, so da3 die Strecke zwischen Wasserzufuhr und Materialaustritt etv-a 12-15 mal länger ist als der lichte Durchmesser des MaterialzuführungsSchlauches, und die zugeführte Vassermenge mit einem Druck von größer als 20 bar eingespritzt wird.Of course, the invention is not based on that The embodiment shown and described in detail above is limited, but there are numerous Modifications possible without deviating from the basic idea, a spray nozzle device for To use wetting of material consisting of plaster of paris, cement, filter ash and similar building materials, preferably for "use as route consolidation material or as dam building materials in underground mining, so that the distance between the water supply and the material outlet is about 12-15 times longer than the clear one Diameter of the material supply hose, and the supplied amount of water with a pressure greater than 20 bar is injected.
