Description

Die Erfindung bezieht sich auf eine Vorrichtung zum kontinuierlichen Herstellen und Fördern von einem feinverteilte Mikroluftporen enthaltenden Putzmörtel o. dgl. mit einem Vorratsbehälter, einer Flüssigkeitszuführung und einem in Fallrichtung liegenden Mischraum, in welchem mittig eine motorisch angetriebene Mischwerkswelle mit Mischwerkzeugen angeordnet ist sowie einer an der Austragsseite des Mischraums angeordneten Absaugvorrichtung, wobei die Mischwerkzeuge aus mindestens einer quer zur Mischwerkswelle angeordneten Mischscheibe bestehen, die mindestens auf der Oberseite radial oder annähernd radial verlaufende, annähernd aufrechtstehende Paddel o. dgl. aufweist, und die freien Außenränder der Mischscheibe bzw. der zugeordneten Paddel durch einen schmalen Ringspalt von der Mischraumwand getrennt sind.The invention relates to a device for the continuous production and conveying of a finely divided plastering mortar or the like containing micro-air pores, with a storage container, a liquid supply and a mixing chamber lying in the direction of the fall, in which a motor-driven mixer shaft with mixing tools is arranged in the center and one on the Discharge device arranged on the discharge side of the mixing chamber, the mixing tools consisting of at least one mixing disk arranged transversely to the mixing shaft, which has at least radially or approximately radially extending, approximately upright paddles or the like on the upper side, and the free outer edges of the mixing disk or the associated paddles are separated from the mixing room wall by a narrow annular gap.

In der EP-A1-0019288 (veröffentlicht am 26.11.1980) ist bereits eine derartige Vorrichtung vorgeschlagen worden. Die einzige radial verlaufende Mischscheibe weist auf ihrer Oberseite radial verlaufende Paddel und auf ihrer Unterseite die Turbulenzen erhöhende stiftförmige Elemente auf. Auch wenn mit dieser vorgeschlagenen Vorrichtung ein relativ hoher Anteil an feinverteilten Mikroluftporen erhalten werden kann, ist doch der Weg des Mischgutes vom Zeitpunkt der Benetzung bis zur Zuleitung an die Absaugvorrichtung relativ kurz.Such a device has already been proposed in EP-A1-0019288 (published on November 26, 1980). The only radially extending mixing disk has radially extending paddles on its upper side and pin-shaped elements on its underside which increase the turbulence. Even if a relatively high proportion of finely divided micro-air pores can be obtained with this proposed device, the path of the mixed material from the time of wetting to the supply line to the suction device is relatively short.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung des eingangs erwähnten Typs nicht nur den Anteil der feinverteilten Mikroluftporen zu vergrößern, sondern auch durch ein besonderes Umlenkungssystem die Förderung des Mischgutes in der Vorrichtung zu verbessern.The invention has for its object not only to increase the proportion of finely divided micro-air pores in a device of the type mentioned, but also to improve the conveyance of the mixed material in the device by means of a special deflection system.

Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß mindestens zwei Mischscheiben mit einer kegelförmigen Neigung von innen oben nach außen abwärts vorgesehen sind, welche auf ihrer Unterseite annähernd radial verlaufende, annähernd aufrechtstehende Paddel aufweisen, und daß die Mischscheiben mit an der Mischrauminnenwand rundum dicht angeschlossenen Mischraumzwischenböden abwechseln, wobei letztere eine kegelstumpfartige Neigung von außen oben nach innen abwärts aufweisen.The object is achieved in that, according to the invention, at least two mixing disks are provided with a conical inclination from the inside upwards to the outside downwards, which have approximately radially extending, approximately upright paddles on their underside, and that the mixing disks alternate with mixing-space intermediate floors which are tightly connected to the inside of the mixing-room wall , the latter having a truncated cone-like inclination from the top outside downward.

Durch die Schrägstellung der Mischscheiben und der Mischraumzwischenböden wird nicht nur die Rutschfähigkeit des Mischgutes im Mischrohr erhöht, sondern es wird eine mehrfache Zick-Zack-Führung von innen nach außen und wiederum von außen nach innen herbeigeführt, wodurch Engpässe mit Erweiterungen abwechseln, was wiederum erhebliche Einwirkungen auf die mitgeführte Luft hat.The inclined position of the mixing discs and the intermediate floors of the mixing chamber not only increases the slippage of the material to be mixed in the mixing tube, but also creates multiple zigzag guides from the inside out and in turn from the outside in, which alternate bottlenecks with extensions, which in turn is significant Has an impact on the air carried.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Mischwerkzeuge jeweils an der Oberseite der Mischscheibe zur Drehachse nach außen und die Paddel an der Unterseite der Mischscheibe zur Drehachse nach innen verschränkt.According to a preferred embodiment of the invention, the mixing tools are each folded outwards on the upper side of the mixing disk with respect to the axis of rotation and the paddles on the underside of the mixing disk are inwardly folded with the axis of rotation.

Es kann eine trichterförmige Ringwand oberhalb der obersten Mischscheibe einen Ringspalt für das Trockengut freigebend vorgesehen sein, welche über eine zylindrische Kammer mit Flüssigkeit versorgbar ist. Zwischen der trichterförmigen Ringwand und einem mit Kratzern versehenen Drehzylinder kann ein schmaler Ringspalt für die Zuführung des Trockenguts vorgesehen sein; bei einer seitlichen Zuführung des Trockenguts sind zweckmäßigerweise eine Luftzuführung und eine Flüssigkeitszuführung von oben vorgesehen.A funnel-shaped ring wall can be provided above the uppermost mixing disk, releasing an annular gap for the dry material, which can be supplied with liquid via a cylindrical chamber. A narrow annular gap can be provided between the funnel-shaped ring wall and a rotating cylinder provided with scratches for the supply of the dry material; in the case of a lateral supply of the dry material, an air supply and a liquid supply are expediently provided from above.

Eine Vorrichtung zum kontinuierlichen Herstellen und Fördern von Putzmörtel weist ein lotrechtes Mischrohr 1 mit einem Deckel 2 auf, welcher einen Elektromotor 3 zum Drehantrieb einer Mischwerkswelle 4 bzw. einer daran befestigten Hülse 5 trägt; das Mischrohr weist weiterhin einen waagerechten Boden 6 mit einer mittigen Öffnung 7 zum Anschluß 8 der Saugseite einer Exzenter-Schneckenpumpe auf. Am Mischrohr 1 ist ein durch einen Schieber 9 absperrbarer Anschluß 10 einer Hand-, Sack-, Silo- oder Vormischer-Zuspeisung 11 sowie eine in einem stationären Zylinderteil 12 gelagerte Wasserzuführung 13 mit Sprühdüsen 14 angeordnet, von denen wenigstens zwei vorgesehen sind. Am Mischrohr 1 sind stationär fest an seiner Innenwand ein Trichter 15 und zwei Zwischenböden 16, die nach innen abwärts kegelförmig geneigt sind, befestigt.A device for the continuous production and delivery of plastering mortar has a vertical mixing tube 1 with a cover 2, which carries an electric motor 3 for rotating a mixer shaft 4 or a sleeve 5 fastened thereon; the mixing tube also has a horizontal base 6 with a central opening 7 for connection 8 of the suction side of an eccentric screw pump. On the mixing tube 1 is a lockable by a slide 9 port 10 of a manual, bag, silo or premixer feed 11 and a water supply 13 mounted in a stationary cylinder part 12 with spray nozzles 14, of which at least two are provided. On the mixing tube 1, a funnel 15 and two intermediate floors 16, which are inclined conically downwards, are fixedly attached to its inner wall.

An der Mischwerkswelle 4 bzw. der mit ihr drehenden Hülse 5 sind drei Mischscheiben 17, 18 und 19 angebracht, die ringsum dicht an der Hülse 5 angeschlossen und von innen oben nach außen unten kegelförmig geneigt sind. Diese tragen auf ihrer Ober- und Unterseite - bei 19 nur auf der Oberseite - Paddel 20; die Paddel können verschiedene Formen haben. Als entsprechende Beispiele sind jeweils rechts und links zwei unterschiedliche Formen angedeutet; sie können von einer rein radialen Richtung abgewinkelt und zur Drehachse verschränkt sein, um die Förderwirkung zu erhöhen; sie sind z. B. auf der Oberseite in Richtung nach auswärts und auf der Unterseite in der Richtung nach einwärts verschränkt. Die Mischscheiben 17, 18 und 19 sind von der Innenwand des Mischrohres 1 beabstandet, so daß ein verengter Ringspalt entsteht.On the mixer shaft 4 or the sleeve 5 rotating with it, three mixing disks 17, 18 and 19 are attached, which are connected tightly all around to the sleeve 5 and are inclined conically from top to bottom. These carry paddles 20 on their top and bottom - at 19 only on the top; the paddles can have different shapes. Two different shapes are indicated on the right and left as corresponding examples; they can be angled from a purely radial direction and entangled with the axis of rotation in order to increase the conveying effect; they are e.g. B. on the top in the outward direction and on the underside in the inward direction. The mixing disks 17, 18 and 19 are spaced from the inner wall of the mixing tube 1, so that a narrowed annular gap is formed.

Die Zwischenböden 16 sind von der Hülse 5 beabstandet, so daß dort ein Ringspalt 22 entsteht.The intermediate floors 16 are spaced from the sleeve 5, so that there is an annular gap 22.

Das Mischgut durchläuft das Mischrohr 1 auf einem Zick-Zackweg von oben innen nach außen unten und wieder nach innen unten und wieder nach außen unten usw., je nach Zahl der Mischkammern, die zwischen den Zwischenböden 16 vorgesehen sind.The mix passes through the mixing tube 1 a zigzag path from the top inside to the bottom outside and back to the inside and back to the bottom, etc., depending on the number of mixing chambers provided between the intermediate floors 16.

Ein im Mischrohr 1 angeordneter Zylinder 23 ist über Rippenstege 24 mit der Mischwerkswelle 4 drehbar verbunden. Der Zylinder 23 endet unten über der obersten Mischscheibe 17 auf der Höhe des Endes des Trichters 15.A cylinder 23 arranged in the mixing tube 1 is rotatably connected to the mixer shaft 4 via rib webs 24. The cylinder 23 ends below the top mixing disk 17 at the level of the end of the funnel 15.

Das von den Sprühdüsen 14 auf die Oberseite der Mischscheibe 17 aufgesprühte Wasser trifft aufgrund deren Kegelneigung und Drehung in sehr gleichmäßiger Verteilung auf das an der Mündung des Trichters 15 anlangende Trockengut, welches am Anschluß 10 von Kratzern 25 eines mit der Mischwerkswelle 4 drehenden Zylinders 26 mitgenommen und über einen Ringspalt 29 verteilt worden ist.The water sprayed from the spray nozzles 14 onto the top of the mixing disk 17, due to its taper and rotation, hits the dry material arriving at the mouth of the funnel 15 in a very uniform distribution, which is carried along at the connection 10 by scratches 25 of a cylinder 26 rotating with the mixer shaft 4 and has been distributed over an annular gap 29.

Im Ringraum zwischen dem Zylinder 26 und den Zylinderteilen 12 bzw. 23 kann durch Löcher 27 und 28 Luft von oben außen eintreten. Schon beim Eintritt in das Mischrohr werden also das Trockengut, Wasser und Luft miteinander vermischt. Dieser Mischeffekt wird innerhalb jeder Mischkammer wiederholt und durch die Paddel 20 und die Umlenkungen an den Ringspalten 21 und 22 verstärkt. Dabei folgt auf dem Förderweg jeder Verengung eine Erweiterung des Mischraumes. Schon in der ersten Mischkammer kann die Luft unterhalb des Trichters 15 zu einem Polster mit Druckspeicherwirkung ansammeln, welche der Weiterförderung dient. Andererseits ist ein relativ weiter Förderweg vom Ringspalt 21 unter der Mischscheibe 19 bis zur Saugstelle der Pumpe, so daß von der Saugwirkung der letzteren kein schädlicher Einfluß zu befürchten ist.In the annular space between the cylinder 26 and the cylinder parts 12 and 23, air can enter from outside through holes 27 and 28. As soon as you enter the mixing tube, the dry material, water and air are mixed together. This mixing effect is repeated within each mixing chamber and reinforced by the paddles 20 and the deflections at the annular gaps 21 and 22. Each constriction on the conveyor path is followed by an expansion of the mixing room. Already in the first mixing chamber, the air can accumulate below the funnel 15 to form a cushion with an accumulator effect, which serves for further conveyance. On the other hand, there is a relatively long conveying path from the annular gap 21 under the mixing disk 19 to the suction point of the pump, so that the suction effect of the latter does not have to be harmful.

In der kühlen Jahreszeit kann es vorteilhaft sein, wenn der Luftzutrittsstelle 27 in Fig. 1 vom darüber angeordneten Elektromotor erwärmte Luft zugeführt werden kann.In the cool season, it can be advantageous if the air access point 27 in FIG. 1 can be supplied with air heated by the electric motor arranged above it.

Fig. 4 zeigt eine Vorrichtung in stark geneigter Lage. In bezug auf ihre Drehachse ist der Aufbau der Mischkammern mit ihren Zwischenböden und mit den in sie hineinragenden Trägern für die Paddel der gleiche wie anhand von Fig. 1-3 beschrieben. Für gleiche oder ähnliche Teile sind daher in Fig. 4 auch die gleichen Bezugsziffern verwendet.Fig. 4 shows a device in a strongly inclined position. With regard to its axis of rotation, the structure of the mixing chambers with their intermediate floors and with the supports for the paddles projecting into them is the same as described with reference to FIGS. 1-3. The same reference numbers are therefore used in FIG. 4 for the same or similar parts.

Die geneigte Lage erfordert eine Änderung an der Zuführung des Trockenguts; in Achsnähe unter der Öffnung bzw. dem Anschluß 10 wird das Trockengut einer obersten mit der Mischwerkswelle 4 mitdrehenden, nach abwärts kegelig geneigten Mischscheibe 30 zugeführt, auf deren Oberseite Paddel 20 angebracht sind. Das Gut kommt in eine durch eine Zwischenhalbwand 31 getrennte Wanne 32, wobei auf der gegenüberliegenden Seite der Zwischenhalbwand 31 Wassersprühdüsen liegen, welche in einer Halbringleitung 13 gespeist werden. Die mittige Öffnung 7 für den Anschluß 8 der Förderpumpe ist in der oberen Hälfte - bezogen auf die Horizontale - von einem Ringkragen 33 umgeben.The inclined position requires a change in the supply of the dry material; in the vicinity of the axis under the opening or the connection 10, the dry material is fed to an uppermost mixing disk 30 which rotates with the mixer shaft 4 and is tapered downwards, on the upper side of which paddles 20 are attached. The material comes into a trough 32 which is separated by an intermediate half wall 31, water spray nozzles lying on the opposite side of the intermediate half wall 31, which are fed in a half ring line 13. The central opening 7 for the connection 8 of the feed pump is surrounded in the upper half - with respect to the horizontal - by an annular collar 33.
