Description

Die Erfindung. betrifft eine Mischmaschine zur Herstellung von Gemischen aus, Stoffen festen Aggregatzustandes in kontinuierlichem Arbeitsgang. Insbesondere ist die Maschine für die Herstellung von Mürtel, Beton u. dgl. geeignet.The invention. relates to a mixing machine for the production of mixtures from, substances in a solid aggregate state in a continuous process. In particular the machine is suitable for the production of cheesecloth, concrete and the like.

Es sind kontinuierlich arbeitende Mischmaschinen bekannt, bei denen die Zuführung des Gutes durch eine Transportvorrichtung erfolgt und die eine -geneigte, über ihre Länge in Form einer Spirale mit Mischstäben besetzte Antriebswelle besitzen, welche innerhalb eines liegenden, oben offenen Troges angeordnet ist. Die Austragung des gemischten Gutes geschieht am Trogende durch eine Öffnung am Trog.There are continuously operating mixers known in which the goods are fed in by a transport device and the one inclined, have a drive shaft fitted with mixing rods over their length in the form of a spiral, which is arranged within a lying, open-topped trough. The event of the mixed goods happens at the end of the trough through an opening at the trough.

Eine solche Einrichtung hat mehrere Mängel. Zunächst sind zur Zufuhrregelung der Mischstoffe besondere Einrichtungen notwendig, die eine be sondere Bedienung und eine nicht unbeträchtliche Bauhöhe erfordern. Da zudem auch die Ausschüttung aus dem Trog senkrecht erfolgt und Transportgeräte unter die Ausschüttöffnung geschoben werden müssen, muß das geneigte Trogende ebenfalls hoch. liegen. Diese Bauweise erfordert einen großen Materialverbrauch und daher größere Herstellungskosten und zudem einen; entsprechend hohen: Kraftaufwand zur Zuführung der Mischstoffe zum Trog.Such an arrangement has several shortcomings. First are to regulate the supply The mixed materials require special facilities that require special operation and require a not inconsiderable overall height. There is also the distribution takes place vertically out of the trough and pushes transport devices under the discharge opening must be, the sloping trough end must also be high. lie. This construction requires a large consumption of materials and therefore greater manufacturing costs and also one; correspondingly high: effort required to feed the mixed materials to the Trough.

Diese Mängel werden erfindungsgemäß dadurch beseitigt, daß die Förderschnecken entsprechend den von: ihnen zu fördernden Teilmengen mit verschiedenen Drehzahlen angetrieben werden und durch Getrieberäder mit der Mischwelle gekuppelt sind.- Des weiteren wird die Ausschüttvorrichtung als am Trogende quer zur Trogachse und unter einem Winkel zur Vertikalachse angeordneter Trichter gestaltet. Der Kraftersparnis dient auch der Vorschlag, das etwa beider Mischung erforderliche Wasser nur auf dem letzten Teil des Transportweges im Trog dem Mischgut zuzuführen.These shortcomings are eliminated according to the invention in that the screw conveyors according to the subsets to be conveyed by them at different speeds are driven and are coupled to the mixing shaft by gear wheels further is the dispensing device than at the end of the trough transversely to the trough axis and below designed at an angle to the vertical axis arranged funnel. The energy saving The suggestion is also used to only add up the water required for both mixing to be fed to the mix in the last part of the transport route in the trough.

In der Zeichnung ist die Erfindung als Beispiel für eine Betonmischvorrichtung schematisch dargestellt, und zwar zeigt Abb. i die Maschine im Längsschnitt und Abb. 2 im Grund:riß.In the drawing the invention is shown as an example of a concrete mixing device shown schematically, namely Fig. i shows the machine in longitudinal section and Fig. 2 in the bottom: crack.

In diesen Abbildungen bezeichnet 6 Transportschnecken. 8 eine Ausschüttvorrichtung, io einen Trog, 12 eine Antriebswelle mit ihrem Antrieb. 1q., der auch die Transportschnecken 6 antreibt, 16 an der Welle 12 befestigte Mischstäbe, 18 eine Wasserzuleitung und 2o einen Ausschütttrichter für den gemischten Beton.In these figures 6 denotes conveyor screws. 8 a dispensing device, io a trough, 12 a drive shaft with its drive. 1q., Which is also the conveyor screw 6 drives, 16 attached to the shaft 12 mixing rods, 18 a water supply and 2o a pouring funnel for the mixed concrete.

Sand und Zement werden in trockenem Zustand ununterbrochen in die Transportschnecken 6 eingefüllt, wobei die Einrichtung getroffen ist, daß die Sandtransport.schnecke sich entsprechend dem gewünschten Mischungsverhältnis schneller dreht und somit mehr fördert als die Zementtransportschnecke. Der Sand gelangt mit dem Zement aus den Transportschnecken über die Ausschüttvorrichtung 8 in den Trog io. Dieser steht eben und ist am Boden befestigt; er ist von oben leicht zugänglich und nimmt in seiner Längsrichtung die Mischwelle 12 auf. -Sie ist mit Stäben 16 besetzt, die gegeneinander so versetzt sind, d.aß sie entlang der Antriebswelle 12 eine Spirale bilden.. Sand und Zement wird von den, Mischstäben 16 bei der Drehung der Welle 12 erfaßt, durchmischt und dabei auch in der Spiralrichtung innerhalb des Troges io weitergefördert. Da die Mischstoffe noch trocken sind, wird hierzu nur eine geringe Arbeitsleistung gebraucht. Nachdem die Trockenmischung über eine gewisse Strecke des. Förderweges durchgeführt ist, wird dem Trog durch das Rohr i8 Wasser zugeführt, und die weitere Mischung auf dem, restlichen Transportwege im breiigen Zustande vollzogen,. Am Trogende fällt das fertige Gemisch durch den Ausschütttrichter 2o in unter ihn geschobene Gefäße, in denen er zur Verwendungsstelle gebracht wird. Der Ausschütttrichter ist in der Ausschubrichtung schräg nach vorn gerichtet, um an Höhe zu sparen.Sand and cement are continuously in the dry state Filled transport screw 6, the device is made that the Sandtransport.schnecke rotates faster according to the desired mixing ratio and thus conveys more than the cement conveyor screw. The sand comes out with the cement the screw conveyor via the dispensing device 8 into the trough io. This one stands flat and attached to the ground; it is easily accessible from above and takes in the mixing shaft 12 in its longitudinal direction. -She is staffed with 16 staffs are offset from one another in such a way that they form a spiral along the drive shaft 12 Form .. Sand and cement is released from the, mixing rods 16 as the shaft rotates 12 detected, mixed and thereby also in the spiral direction within the trough io further promoted. Since the mixed materials are still dry, this is only a small one Work needed. After the dry mix over a certain distance the conveying path is carried out, water is fed to the trough through pipe i8, and the further mixing on the remaining transport routes in a pulpy state completed. At the end of the trough, the finished mixture falls through the pouring funnel 2o in vessels pushed under it, in which it is brought to the point of use. The discharge funnel is directed obliquely forward in the ejection direction to save height.

Bei dem Antrieb der Mischwelle 12 vom Trichterende des Troges io aus. wird die Gefahr des Eiiidringens von Mischstoffen in das Endlager und somit des. Auslaufens des Lagers erheblich vermindert.When driving the mixing shaft 12 from the funnel end of the trough io. the risk of mixed materials penetrating into the repository and thus the. Leakage of the bearing is considerably reduced.
