Abstract

The refractory mass initially fed in dry, will be mixed with water to a consistency suitable for pumping it the rest of the way to the nozzle. Typically the refractory mass is asbestos or refractory wool with cement. The method is esp. useful for applying material to high-rise buildings etc. e.g. on the roof sections. Dust free operating is achieved.

Description

Beschreibung und Erlauterung zur PatentanmeldungDescription and explanation of the patent application

"Vorrichtung zum Naßverspritzen von feuerfesten Massen" Zum Vers;ritzen von feuerfesten Passen wie Spritzasbest, Steinwolle mit Zement und ähnlichen Zusammensetzungen benutzt man ausschließlich Maschinen, die die genannten feuerfesten Massen trocken einem Blasschlauch zuführen, und am Ende des Schlauches, unmittelbar im Bereich des feuerfesten Massenaustritts, wird der trockenen Nasse Wasser, z.B. mit einem Bindemittel versetzt, zugeführt."Device for the wet spraying of refractory masses" To the verse; scoring of refractory fittings such as sprayed asbestos, rock wool with cement and similar compositions only machines are used that dry the refractory masses mentioned a blow hose, and at the end of the hose, immediately in the area of the refractory mass outlet, the dry wet water, e.g. with a Binder added, supplied.

Der Rückprall, der bei dieser ;rt des Verspritzens entsteht, und die Staubentwicklungen sind nennenswert.The rebound that occurs with this type of splash, and the Dust developments are noteworthy.

Es ist daher vielfach versucht worden, die Nassen, bevor sie einer Spritzmaschine zugeführt werden, naß zu mischen, um sie dann, z.B. über eine Verdrängerpumpe, die aa Ende noch zusätzlich mit Luft aus dem Schlauch zum auftragen der Hasse bestickt ist, zusetzen.It has therefore been tried many times, the wet before one Injection machine, to be mixed wet, in order to then, e.g. via a displacement pump, the aa end additionally embroidered with air from the hose to apply the hatred is to add.

Diese Maschinen haben bei dem Eintragen von feuerfesten Massen, z.B. im Hochbau, keinen Einsatzpunkt mehr, sondern nur ganz vereinzelt.These machines have a lot to do with the introduction of refractory masses, e.g. in building construction, no longer a point of use, but only very sporadically.

Der Nachteil liegt darin, daß 1. zusstzlich ein nasser Mischvorgang durchgeführt werden muß, bevor die Maschine das Platerial naß fördert.The disadvantage is that 1. there is also a wet mixing process carried out must be before the machine conveys the material wet.

Das bedeutet, daß ein zusatzlicher Arbeitsvorgang für das Bedienungspersonal zur Duruhführung der Naßmischung erforderlich ist. This means that an additional work process for the operating personnel for Duruhführung the wet mix is required.

2. Das feuerfeste Material, das im hochbau verspritzt wird, wird in der Regel mit einer Schichtstärke von 30 mm aufgetragen. Das bedeutet, daß bei sehr hoher Wasserzugabe, insbesondere beim Auftragen auf Decken, eine zusitzliche statische Belastung auftritt, die das Gewicht von Gamma 0,4 - 0,5 auf 0,7 - 0,8 heraufsetzt, bevor das material ausgetrocknet ist.2. The refractory material that is sprayed in building construction is in usually applied with a layer thickness of 30 mm. That means that by very high water addition, especially when applying to ceilings, an additional static Load occurs that increases the weight from gamma 0.4-0.5 to 0.7-0.8, before the material has dried out.

Um diese Nachteile bei der nassen Auftragstechnik für feuerfeste assn, vorzugsweise für den Hochbau, zu vermeiden und den Nachteil der trockenen feuerfesten Hassenauftragstechnik, die darin besteht, daß 1. ein den Menschen belästigender und vielfach auch gefährdender Staub beim Auftragen erzeugt wird und 2. die feuerfesten Passen nicht homogenisiert mit einem feststehenden Mischungsverhältnis gespritzt werden, wird erfindungsgemäß vorgeschlagen, eine Vorrichtung zum Auftragen von feuerfesten Melassen, die 1. eine staubfreie Austragstechnik und 2. ein gewünschtes Verhältnis zwischen der trockenen, feuerfesten Hasse und den flüssigen Bindungsmittel gewährleistet, zu verwenden.To avoid these disadvantages of the wet application technique for refractory assn, preferably for building construction, and avoid the disadvantage of dry refractory Hate application technique which consists of 1. a harassing man and often hazardous dust is generated during application and 2. the fireproof Fit not homogenized injected with a fixed mixing ratio are proposed according to the invention, a device for applying refractories Molasses, the 1. a dust-free discharge technology and 2. a desired ratio between the dry, refractory hate and the liquid binding agent ensured, to use.

In der beiliegenden Zeichnung ist die erfindungsgenaße Vorrichtung darEestellt: mit 1 der Fülltrichter, in den das Material wie beim 'llrockenspritzverfahren aufgegeben wird; mit 2 eine Zuteilschnecke, die das material einer erfindungsgemäß angeordneten Kontinuitäts- und Nischkammer (3) zuführt.In the accompanying drawing is the inventive device Represented: with 1 the filling funnel into which the material is poured as in the case of the dry injection molding process is abandoned; with 2 a metering screw, which is the material of an inventive arranged continuity and niche chamber (3) supplies.

In dieser kammer werden die trockenen Nassen mit Flüssigkeit durch die eingesetzten Bedüsungsstutzen (4) im gewünschten Verhältnis benetzt.In this chamber, the dry wet with liquid through the nozzle nozzle (4) used is wetted in the desired ratio.

Bei den zugeführten Flüssigkeiten kann es sich auch um Nehrkompenentenlösungen handeln.The liquids supplied can also be minor component solutions Act.

Weiterhin bewirkt die Kontinuitätskammer, daß die zu verspritzenden Nassen beim Nischen von Flüssigkeit und trocken masse vor dem eigentlichen Verdrängerkörper einer Pumpe (5) so vorgedichtet wird, daß sie das Material luftblasenfrei dem Pumpenfördervorgang zuführt.Furthermore, the continuity chamber causes the to be sprayed Wet when mixing liquid and dry matter in front of the actual displacer a pump (5) is pre-sealed in such a way that it transfers the material to the pump delivery process without air bubbles feeds.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte und beschriebene Ausbildungsform beschrankt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Vorrichtung zum Verspritzen von feuerfesten Massen so zu errichten, daß die feuerfesten Nassen trocken der Pumpenvorrichtung zugegeben Wterdv können und hinter dem Einzeltrichter und dem Zuteilorgan eine Kontinuitätskammer angesetzt ist, die ein Mischen der trockenen, feuerfesten Nasse mit den gewünschten Flüssigkeitsmengen garantiert und gleichzeitig dabei erfindungsgemäß eine Vorverdichtung der feuerfesten Massen zwangsläufig erzielt, so daß Zwischenraume mit Lufteinschlüssen beim Pumpenvorgang ausgeschlossen werden und ein optimiertes Verhältnis zwischen gemischter, feuerfester Masse und dem tragenden Luftstrahl am Förderschlauch-Austragsende der Vorrichtung gewährleistet ist.Of course, the invention is not limited to the above in detail The form of training shown and described is limited, but there are numerous Changes possible, but without changing the basic idea to deviate to erect a device for spraying refractory masses so that the Refractory wet dry added to the pump device Wterdv can and behind a continuity chamber is attached to the single funnel and the allocation organ, which mixing the dry, refractory wet with the desired amounts of liquid guaranteed and at the same time according to the invention a pre-compression of the refractory Masses inevitably achieved, so that spaces with air pockets during the pumping process excluded and an optimized ratio between mixed, refractory Mass and the carrying air jet at the conveyor hose discharge end of the device is guaranteed.
