Abstract

Statischer Mischer zum Mischen mehrerer flüssiger oder pastöser Materialkomponenten, mit mehreren Etagen, in deren Etagenböden Durchtrittsöffnugen sind, und mit Wän­ den in den Etagen zur Aufteilung der Materialkomponenten auf Teilströme und zum Zusammenfassen der Teilströme verschiedener Strömer zu jeweils neuen Strömen, dadurch gekennzeichnet, daß in jeder Etage (2 bis 7) mindestens zwei Strömungsteilerkammern (34, 36) sich befinden, die mindes­ tens in einem Teilbereich übereinander liegen, daß jede dieser übereinanderliegenden Strömungsteilerkammern eine den ankommenden Strom teilende Strömungsteiler­ wand (58) aufweist, daß mit jeder der übereinanderliegen­ den Strömungsteilerkammern eine andere Durchtrittsöff­ nung (50, 52) des Etagenbodens (46) in Verbindung steht, daß die Strömungsteilerkammern mit beidseitig von ihnen angeordneten Mischkammern (42, 44) in Verbindung stehten, und daß die aufeinanderfolgenden Etagen im gleichen Drehsinn fortlaufend winkelverdreht zueinander angeordnet sind und die Winkelverdrehung jeweils so groß ist, daß jeweils die Mischkammern einer unteren Etage mit den Durchtrittsöffnungen des Etagenbodens einer darüber angeordneten Etage in Verbindung stehen. Dadurch wird mit kleinerer Bauweise eine bessere Durchmischung der Mater­ ialkomponenten sowie eine vereinfachte Herstellung erzielt. Static mixer for mixing several liquid or pasty material components, with several floors, in whose floors are passage openings, and with walls the one in the floors for dividing the material components on partial flows and to summarize the partial flows different streams to new streams, thereby characterized in that on each floor (2 to 7) at least two Flow divider chambers (34, 36) are located, the at least at least in a partial area one above the other that each of these superimposed flow divider chambers a flow divider dividing the incoming stream wall (58) has that with each of the superimposed the flow divider chambers another passage opening tion (50, 52) of the floor (46) is connected, that the flow divider chambers on both sides of them arranged mixing chambers (42, 44) in connection stood, and that the successive floors in the same direction of rotation continuously rotated at an angle to each other are arranged and the angular rotation each so large is that the mixing chambers each have a lower floor the passage openings of the floor one above arranged floor. This will help with smaller design better mixing of the mater ial components and simplified production.
