Description

Betonmischtrommeln sind in den verschiedensten Ausführungen bekannt, desgleichen auch solche mit Leitschaufeln.Concrete mixing drums are known in various designs, likewise those with guide vanes.

Das Neue der Erfindung wird in Mlschleltwänden gesehen, die auf der Innenwand der Trommel geschweißt befestigt sind. Dieselben haben im Querschnitt gesehen, die Form eines Dreiecks mit ungleichmäßigen Schenkeln. Die Mischleitwände wirken wie Leitschaufeln und leitete das Mischgut in die Hauptmischzone, so daß das angestrebte intensive Mischen gleichzeitig nach zwei Achsen eintritt. Die Mischleitwände können annähernd rechtwinklig sein, sind aber jedenfalls ungl@eichschenklig. Der längere Schenkel wälzt das Mischgut zur Mitte der Trommel, und es fällt dann über den steilen Schenkel wieder ab zur Wand. Durch die Neigung der scharfen Winkelkante gegenüber der Trommelachse von Mitte Boden bis zum Rande der Trommel am Kegelansatz wird dias Mischgut vom Boden hochgewälzt und fällt in der Trommelmitte wieder zusammen. Dieser Vorgang wiederholt sich bei jeder Mischwand, und es wird hierdurch ein inniges, schnelles und geräuscharmes Mischen erzielt.The novelty of the invention is seen in Mlschleltwilden, which on the Inner wall of the drum are welded attached. The same have in cross section seen the shape of a triangle with uneven legs. The mixed baffles act like guide vanes and diverted the mix into the main mixing zone so that the desired intensive mixing occurs simultaneously on two axes. The mixed baffles can be approximately right-angled, but are in any case unevenly legged. Of the The longer leg rolls the mix towards the center of the drum and it then falls over the steep side back to the wall. Due to the inclination of the sharp angled edge opposite the drum axis from the middle of the bottom to the edge of the drum at the cone base the mix is rolled up from the floor and collapses again in the middle of the drum. This process is repeated with every mixed wall, and this creates an intimate, quick and quiet mixing achieved.

Diese Mischtrommel ist sehr leicht zu reinigen, da keine schlecht zugänglichen Ecken vorhanden sind, an denen sieh das Mischgut festsetzen könnte. In der Zeichnung zeigt Fig. i Ansicht einer offenen Trommel, Fig. 2 Draufsicht auf eine liegende Trommel, teils im Horizontalschnitt, Fig. 3 einen Schnitt A-B.This mixing drum is very easy to clean as it is not bad There are accessible corners where the mix could get stuck. In the drawing, FIG. 1 shows a view of an open drum, FIG. 2 shows a plan view a lying drum, partly in horizontal section, Fig. 3 a section A-B.

Die bekannte Innenwandung i der Mischtromme12 ist neu mit aufgeschweißten Mischleitwänden 3 ausgerüstet. Dieselben sind: im Querschnitt gesehen in einem Winkel von 25 bis a5° gestaltet und ungleichschenklig geformt. Beispielsweise ist die Schenkelseite 5 länger als die Seite 6. Zweckdienlich kann man denLeitwänden eineNeigung gegenüber der Trommelachse geben. Der Zahnkranz 9 besteht im Gegensatz zu anderen Mischern aus etwa fünf Segmenten, damit nach Ausbrechen eines Zahnes nicht der ganze teure Zahnkranz erneuert werden muß. Die Mischtrommelwände sind innen glatt. Die Sehrauben am Boden und die Befestigungsschrauben der Ausstoßzungen sind versenkt. die Zunge selbst verschweißt, damit kein Mischgut in den Ecken hängen bleibt.The well-known inner wall i of the mixing drum12 is now welded on Mixing baffles 3 equipped. The same are: seen in cross section at an angle designed from 25 to a5 ° and shaped with unequal legs. For example, is the leg side 5 longer than side 6. Appropriately, one can incline towards the baffles the drum axis. The ring gear 9 is in contrast to other mixers from about five segments, so after breaking out a tooth not the whole expensive one Ring gear needs to be replaced. The walls of the mixing drum are smooth on the inside. The very robes on the floor and the fastening screws of the ejector tongues are countersunk. the tongue self-welded so that no mix gets stuck in the corners.
