Statischer MischerStatic mixer

Die Erfindung betrifft einen statischen Mischer zum Vermischen, von zwei oder mehreren flüssigen oder pastösen , strömenden Komponenten.The invention relates to a static mixer for mixing, two or more liquid or pasty, flowing components.

Der Erfindung liegt die Aufgabe zugrunde , zwei oder mehrere Flüssigkeiten oder Pasten , die sich in strömen dem Zustand befinden, mit Hilfe eines Mischers, der beweglichen mechanischen Mischelemente besitzt, zu ver= tischen.The invention is based on the object of two or more liquids or pastes that flow in are in the state of ver = with the help of a mixer that has movable mechanical mixing elements tables.

Erfiadungsgemäß wird das dadurch erreicht , daß in einem statischen Mischer einmal oder mehrfach der Strom der zu vermischenden Komponenten in Teilströme geteilt wird und alle diese Teiströme in einem Mlschraum gleichzeitig wink= lig und oder entgegengerichtet wieder zusammengeführt werden.According to the invention this is achieved in that in one static mixer once or several times the flow of the components to be mixed is divided into partial flows and all of these partial flows in one garbage room at the same time wink = lig and or are brought together again in the opposite direction.

Die Erfindung beruht auf dem Gedanken ,daß die beim Zu= sainentritt der Teilströme auftretende Verwirbelung eine intensive Vermischung der Phasen bewirkt.The invention is based on the idea that when to = As a result, turbulence occurs in the partial flows causes intensive mixing of the phases.

Aufgrund dieser intensiven Vermischung zeigt der erfindungs= gemäße Mischer auch bei sehr kleiner Baugröße eine hohe Mischleistung.Es ist daher auch der Einbau in räumlich sehr begrenze Betriebseinrichtungen und Fördersysteme möglich.Because of this intensive mixing, the invention shows = Suitable mixers have a high mixing capacity even with a very small size very limited facilities and conveyor systems possible.

Del* erfindungsgemäße Mischer eignet sich zum Vermischen von Flüssigkeiten , Lösungen, Schmelzen oder pastösen Komponenten unterschiedlicher Art , Konzentration, Visko= eität oder Temperatur in geschlossenen Rohrleitungen oder Fördersystemen.Del * mixer according to the invention is suitable for mixing of liquids, solutions, melts or pasty components of different types, concentrations, visco = eity or temperature in closed pipelines or conveyor systems.

Polyisocyanurat- und Polyester-Mehrkomponentenreaktions= systemen.Polyisocyanurate and polyester multi-component reaction systems.

Der erfindungsgemäße Mischer läßt sich weiterhin vor= teilhaft zum Homogenisieren von thermoplastischen Kunststoffschmelzen mit Farbstoffen, Pigmenten oder anderen Additiven als Zusatzeinrichtung an Extrudern oder Spritzgußmaschinen verwenden.The mixer according to the invention can also be used advantageously for homogenizing thermoplastic Plastic melts with dyes, pigments or Use other additives as additional equipment on extruders or injection molding machines.

Der erfindungsgemäße Mischer ist ebenfalls geeignet zur temporären Vermischung von miteinander nickt mischbaren Flüssigkeiten ,wie z.B. öligen und wässrige» Systemen für 7/asch- und Raffinationsprozesse.The mixer according to the invention is also suitable for the temporary mixing of those that are not miscible with one another Liquids such as oily and aqueous »systems for 7 / ash and refining processes.

Eine bevorzugte Ausführungsform der Erfindung ist der Auf= bau aus mechanisch voneinander lösbaren Mischstufen. In jeder Mischstufe wird der Flüssigkeitsstrom der zu ver= mischenden Phasen jeweils einmal in zwei oder mehrere Teil= ströme aufgeteilt und winklig ttnd oder entgegengerich= tet in einem Mischraum gleichzeitig wieder zusammenge= führt. Die Anzahl der Mischstufen kann damit der Misch= barkeit, der Strömungsgeschwindigkeit und der Viskosität angepaßt werden»A preferred embodiment of the invention is the construction of mechanically detachable mixing stages. In at each mixing stage the liquid flow is to be ver = mixing phases each divided into two or more partial currents and angled or opposite direction = are brought together again at the same time in a mixing room. The number of mixing stages can thus be the Mix = availability, the flow rate and the viscosity be adjusted"
