Description
Vorrichtung zum Herstellen von Mischungen, insbesondere von Zement-, Teer-und Asphaltbeton für den Straßenbau Bei den bisher bekannten umlaufenden Mischmaschinen, seien es nun Freifalhnischer, Zwangsmischer oder. Kombination beider Systeme, wird die Mischärbeit geleistet durch Mischorgane, welche dem Mischgut während einer bestimmten Mischzeit eine vorzugsweise umwälzende Grobbewegung erteilen.Device for producing mixtures, in particular cement, Tar and asphalt concrete for road construction In the previously known rotating mixers, be it free falconer, compulsory mixer or. Combination of both systems the mixing work done by mixing elements, which the mixed material during a certain Give the mixing time a preferably circulating coarse movement.
Demgegenüber besteht die Erfindung darin, daß in den umlaufenden, insbesondere für den Straßenbau dienenden Mischer und in das in ihm befindliche Mischgut während des Mischvorganges hochfrequente Schwingungen eingeleitet werden. Die grundlegende Wirkung dieser eingeleiteten Vibration ist zunächst die, daß alle die einzelnen Teilchen des Mischgutes in hochfrequente Mischbewegungen gesetzt werden und damit ihre gegenseitige innere Reibung si^h verringert. Das Mischgut ist damit nicht nur den bekannten, bisher vorzugsweise erzeugten Grobbewegungen, sondern auch noch zusätzlichen Feinbewegungen unterworfen. Da die kleinen und kleinsten Gemischteilchen unter Einwirkung der Schwingungen schneller und gründlicher in die Hohlräume zwischen den gröberen Gemischteilen eindringen, ist damit eine schnellere und bessere Mischung verbunden.In contrast, the invention consists in that in the circulating, in particular for the road construction serving mixer and in it located High-frequency vibrations are introduced during the mixing process. The fundamental effect of this initiated vibration is first of all that all the individual particles of the mix are set in high-frequency mixing movements and thus their mutual internal friction is reduced. The mix is therewith not only the known, previously preferably generated coarse movements, but also subject to additional fine movements. Because the small and smallest particles of the mixture under the action of the vibrations faster and more thoroughly into the cavities between penetrate the coarser parts of the mixture, it is a faster and better mixture tied together.
Die innere Reibung zwischen den einzelnen Mischgutteilchen ist in Auswirkung der eingeleiteten Schwingungen in einem erheblichen Grade aufgehoben; deshalb unterliegen die im Inneren der Mischtrommel umlaufenden oder auch bewegten Misch- und Förderorgane einem wesentlich geringeren Verschleiß. Dieser Vorteil ist um so größer, je mehr Zwang die Mischorgane bei den bisher angewandten bekannten Mischverfahren ausüben mußten.The internal friction between the individual mix particles is in Effect of the introduced vibrations canceled to a considerable degree; therefore are subject to the rotating or moving inside the mixing drum Mixing and conveying elements have a significantly lower level of wear. This advantage is the greater, the more constraint the mixing organs in the known ones used so far Had to practice mixed processes.
Der Böschungswinkel des Mischgutes verringert sich unter Einwirkung der Schwingungen, und es tritt ein Zusammensacken des Mischgutes ein. Damit ist als weiterer Vorteil eine Vergrößerung des Fassungsraumes der Mischmaschine gegeben.The angle of repose of the mix is reduced under the influence the vibrations, and the material to be mixed collapses. So is Another advantage is an increase in the capacity of the mixer.
Die Schwingungen werden zweckmäßig derart eingeleitet; daß an der Einlaufzone des Mischers, also dort, wo die noch ungemischten Bestandteile des ?Mischgutes einlaufen, stärkere Vibrationsbewegungen entstehen als an der Auslaufzone des hTischers, wo sich bereits weitgehend gemischtes Gut befindet.The vibrations are expediently introduced in this way; that at the Inlet zone of the mixer, i.e. where the unmixed components of the? Mixed material run in, stronger vibration movements occur than at the run-out zone of the h table, where there are already largely mixed goods.
