mehrere sich nahezu über die ganze Länge zweier tung arbeiten. Dadurch, daß die Vorrichtung nach der benachbarter Mischkammern erstreckende und Erfindung eine sehr schnelle Homogenisierung erparallel zueinander, zentral bzw. außen angeordnete 45 möglicht, kann sie einen Teil einer Anlage für die Verbindungsrohre vorgesehen sind, wobei von Quer- dauernde kontinuierliche Homogenisierung flüssiger wand zu Querwand abwechselnd einmal ein Zentral- Gemische bilden. Dazu werden im richtigen Verhältrohr und darauffolgend über die Querwand gleich- nis dosierte Ströme der zu mischenden Flüssigkeiten mäßig verteilt mehrere Außenrohre angebracht sind. und gegebenenfalls pulverförmiger fester Stoffe mit Aus der USA.-Patentschrift 2 085 132 ist eine 50 Flüssigkeiten, gegebenenfalls nach einer Vormischung, Mischvorrichtung bekannt, die in erster Linie dazu in die Vorrichtung nach der Erfindung geführt, aus dient, Rohteer od. dgl. mit einer alkalischen Lösung der eine gleiche Menge homogenisierter Flüssigkeit zu behandeln, um die sauren Bestandteile abzutren- oder Suspension dauernd abgelassen wird. Die Intennen. Hierzu wird am unteren Teil der aus z.

The fact that the device according to the adjacent mixing chambers extending and invention a very rapid homogenization erparallel to each other, centrally or externally arranged 45 possible, it can be part of a system for the Connecting pipes are provided, from transverse continuous continuous homogenization of the liquid wall to transverse wall alternately form a central mixture. This is done in the correct ratio pipe and then, over the transverse wall, streams of the liquids to be mixed are metered in the same way moderately distributed several outer pipes are attached. and optionally powdered solids with From the United States patent specification 2 085 132 is a 50 liquids, if necessary after a premix, Mixing device known, which led primarily to this in the device according to the invention from serves, raw tar or the like with an alkaline solution of an equal amount of homogenized liquid to treat to separate the acidic constituents or the suspension is continuously drained. The inside. For this purpose, the lower part of z. B. 15 sity of the circulating current must be a multiple arranged one on top of the other chambers 55 of the supplied and discharged mass flow Mixing device can be a mixture of tar and soda.

Die Homogenisierungsvorrichtung nach Fig. 1 und 2 ist eine Durchströmungsvorrichtung, die aus vier in vertikaler Richtung aufeinanderfolgenden, in Reihe geschalteten Mischkammeni besteht Das zu homogenisierende Gemisch v.ird in die obere Kammer I geführt, die aus einem Zentralrohr 25, einem Mischraum 8 und einem Kranz von Außenrohren 26 besteht. Die Außenrohre 26 setzen sich in den Mischraum 8 der Mischkammer TI fort und bilden dort die Außenrohre 27. Mischkammer Π besitzt außerdem ein Zentralrohr 28, das sich in die Mischkammer III fortsetzt Diese Kammer entspricht der Mischkamraer I und ist, in derselben Weise wie Kammer I mit Kammer II, mit der der Kammer II entsprechenden Kammer IV verbunden. Das homogenisierte Gemisch tritt durch den Stutzen 12 aus. der Vorrichtung aus:The homogenization device according to FIGS. 1 and 2 is a through-flow device which consists of four vertical mixing chambers connected in series Wreath of outer tubes 26 consists. The outer tubes 26 continue into the mixing space 8 of the mixing chamber TI and form the outer tubes 27 there. Mixing chamber Π also has a central tube 28 which continues into the mixing chamber III connected to chamber II, with chamber IV corresponding to chamber II. The homogenized mixture exits through the nozzle 12. the device from:

Mutually arranged mixing chambers are divided io 2 740 616 perforated walls are provided, of which the first with an inflow and which, however, the mixing chambers extend over the last is connected to an outflow and double the height of the distribution and collecting spaces in which As a result, the partial flows run mainly along the length of two adjacent mixing chambers in the longitudinal direction of the device. There are stretching and parallel to one another, centrally or therefore not sudden changes of direction, connecting pipes arranged outside are provided, consequently the homogenizing effect is also not so good, from transverse wall to transverse wall not so good. In the device of the USA patent, a central tube and subsequent writing evidently form dead spaces, so only a small part of the mixing chamber volume is evenly distributed over the transverse wall for several outer tubes, since - ao the homogenization is used,
