   Die Erfindung betrifft eine Vorrichtung zum intensiven Vermischen von verschiedenen schweren Gütern mit Flüssigkeiten, bestehend aus einem Mischbehälter mit zwei um horizontale Achsen rotierenden Mischsystemen, von denen das eine aus einem Rührwerk mit in kleinem Abstand von der Behälterwand laufenden Schaufeln und das andere aus einem frei in den Mischraum kragenden Quirler besteht. 



   Es sind Vorrichtungen für diesen Zweck bekannt, bei denen ein mit einem Leitrohr umgebender Schneckenrührer zentrisch im Mischraum angebracht ist und innerhalb des freien Raumes zwischen dem Leitrohr und der Behälterwand Quirler angeordnet sind. Ferner sind Mischer für Zellenbeton mit einer Schaufelwelle und zwei Quirlern, die im unteren Teil des Behälters, jedoch ausserhalb des von den Schaufeln bestrichenen Raumes angeordnet sind, bekannt. 



   Die für die Produktion von Leichtbeton, im besonderen von Porenbeton, verwendeten Mischer ermöglichen infolge der nicht genügend koordinierten Arbeitsweise ihrer Mischsysteme kein intensives Mischen des gesamten Mischgutes in kurzer Zeit. 



   Die Erfindung verfolgt den Zweck, den genannten Nachteil der bekannten Mischer zu beseitigen und mit vergleichsweise geringem wirtschaftlichen Aufwand ein intensives und schnelles Mischen zu gewährleisten. Dies wird erfindungsgemäss dadurch erreicht, dass der Arbeitsbereich des Quirlers innerhalb des von den Schaufeln des ebenfalls frei, jedoch in der entgegengesetzten Richtung wie der Quirler in den Mischraum kragenden Rührwerkes bestrichenen Ringraumes liegt, wobei beide Mischsysteme sich annähernd über die gesamte Breite des Mischbehälters erstrecken. Bei der erfindungsgemässen Gestaltung des Mischers kragen die Schaufeln und der Quirler aus entgegengesetzten Richtungen frei in den Mischraum.

   Der Quirler wird im unteren Teil des Behälters derart eingebaut, dass die vergleichsweise langsam rotierenden Schaufeln in kleinem Abstand und unterhalb vom schnellrotierenden Quirler laufen und ihm das Mischgut zuführen. Die beiden Mischsysteme wirken auf der ganzen Breite des Mischbehälters. Die Erfindung ermöglicht eine Herstellungskosten sparende Ausführung des Mischers, verringert die Wartungskosten und gewährleistet ein intensives und schnelles Vermischen des gesamten Mischgutes. 



   In den Zeichnungen ist die Erfindung beispielsweise dargestellt.   Fig. l   stellt den Längsschnitt, Fig. 2 den Querschnitt des Mischers dar. 



   Es besteht aus einem oben offenen   Behälter--l--mit   zwei horizontal aus entgegengesetzten Richtungen in ihn frei kragenden Mischsystemen mit den Antriebswellen-3 und 5--, von denen jede nur ein Lager im Behälterbereich besitzt. Die   Schaufeln --4-- sind   derart angebracht, dass sie in kleinem Abstand von der Behälterwand sowie vom   Quirler --6-- laufen   und ihm das   Mischguc-2-zuführen.   Die Behältergrösse ist derart ausgelegt, dass die Oberfläche der   Füllung --2-- unterhalb   der obersten Lage der Mischschaufel--4--

   The invention relates to a device for the intensive mixing of various heavy goods with liquids, consisting of a mixing container with two mixing systems rotating about horizontal axes, one of which consists of an agitator with blades running at a small distance from the container wall and the other of a freely in the mixing chamber protruding whisk.



   Devices for this purpose are known in which a screw stirrer surrounded by a guide tube is mounted centrally in the mixing space and agitators are arranged within the free space between the guide tube and the container wall. Furthermore, mixers for cellular concrete with a blade shaft and two agitators, which are arranged in the lower part of the container but outside the space swept by the blades, are known.



   The mixers used for the production of lightweight concrete, in particular aerated concrete, do not allow intensive mixing of the entire mix in a short time due to the insufficiently coordinated mode of operation of their mixing systems.



   The aim of the invention is to eliminate the mentioned disadvantage of the known mixers and to ensure intensive and rapid mixing with comparatively little economic outlay. According to the invention, this is achieved in that the working area of the agitator lies within the annulus swept by the blades of the agitator, which is also freely but in the opposite direction as the agitator protrudes into the mixing chamber, with both mixing systems extending over approximately the entire width of the mixing container. In the design of the mixer according to the invention, the blades and the agitator protrude freely into the mixing space from opposite directions.

   The agitator is installed in the lower part of the container in such a way that the comparatively slowly rotating paddles run at a small distance from and below the rapidly rotating agitator and feed it with the mix. The two mixing systems work across the entire width of the mixing container. The invention enables the mixer to be designed in a way that saves manufacturing costs, reduces maintenance costs and ensures intensive and rapid mixing of the entire mix.



   The invention is illustrated by way of example in the drawings. Fig. 1 shows the longitudinal section, Fig. 2 shows the cross section of the mixer.



   It consists of a container open at the top - l - with two mixing systems cantilevered horizontally into it from opposite directions with drive shafts 3 and 5, each of which has only one bearing in the container area. The shovels --4-- are attached in such a way that they run a short distance from the container wall and from the whisk --6-- and feed the mixed guc-2-to it. The container size is designed in such a way that the surface of the filling --2-- is below the top layer of the mixing shovel - 4--
