BeschreibungDescription

Misch- und Rührelement zur intensivenMixing and stirring element for intensive

Mischung von Flüssigkeiten mit FlüssigkeitenMixing liquids with liquids

und/oder Flüssigkeiten mit Feststoffenand/or liquids with solids

Die Erfindung betrifft ein Misch- und Rührelement zur effektiveren Durchmischung von Flüssigkeiten. In der Praxis sind verschiedenartige Rührelemente im Einsatz, welche den verschiedenen Aufgaben angepaßt sind.The invention relates to a mixing and stirring element for more effective mixing of liquids. In practice, various types of stirring elements are used, which are adapted to the various tasks.

So werden z.B. sog. Schrägblattrührer mit schräggestellten Rührblättern zur Erzielung einer guten Bewegung und Durchmischung einer oder mehrerer Flüssigkeiten in einem Behälter eingesetzt. Werden z.B. Feststoffe oder schwer aufzulösende Flüssigkeiten einer Flüssigkeit in einem Behälter zur Mischung bzw. zur Homogenisierung zugeführt, werden höhere Turbulenzen als sie ein Schrägblattmischer erzeugt, benötigt. Hierzu werden sog. Scheibenrührer oder Balkenrührer mit vertikal stehenden Rührblättern eingesetzt. Der Vorteil der Schrägblatt-.rührer liegt in einer starken Ausbildung einer axialen Strömung von oben nach unten oder umgekehrt {Drehrichtungswechsel), sodaß auch in ungünstigen Behälterformen wie Rechteckbecken, liegenden Tanks oder dgl. eine gute Ausmischung der Endbereiche und Ecken erfolgt. Die Balkenrührer erzeugen diese Wirkrichtung nicht, bewirken jedoch aufgrund starker Wirbelbildung hinter den Rührblättern eine lokal intensive Mischung sodaß sie für schwierigere Homogenisierungsaufgaben besser geeignet sind.For example, so-called inclined blade agitators with inclined blades are used to achieve good movement and mixing of one or more liquids in a container. If, for example, solids or liquids that are difficult to dissolve are added to a liquid in a container for mixing or homogenization, higher turbulence is required than that generated by an inclined blade mixer. So-called disc agitators or beam agitators with vertically positioned blades are used for this purpose. The advantage of inclined blade agitators is that they create a strong axial flow from top to bottom or vice versa (change of direction of rotation), so that even in unfavorable container shapes such as rectangular basins, horizontal tanks or the like, good mixing of the end areas and corners takes place. Beam agitators do not create this direction of action, but due to the strong vortex formation behind the blades they cause a locally intensive mixing, making them better suited to more difficult homogenization tasks.

Der Erfindung liegt die Aufgabe zugrunde, mit möglichst wenig Energie und apparativem Aufwand möglichst viele Misch- und Rührprozesse bewältigen zu können und die positiven, typischen Eigenschaften der verschiedenen Rührorgane zu vereinen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Rührelement mit symetrisch angeordneten, schräggestellten und vertikalen Rührblättern gebildet wird.The invention is based on the object of being able to handle as many mixing and stirring processes as possible with as little energy and equipment as possible and to combine the positive, typical properties of the various stirring elements. This object is achieved according to the invention by forming a stirring element with symmetrically arranged, inclined and vertical stirring blades.

Vorzugsweise wird dasPreferably, the

Rührelement mit 2x2 oder 3x3 schrägen und geraden Blättern ausgeführt. Der Vorteil des neuen Rührelementes ist gekennzeichnet durch eine intensive Umwälzung eines Behälterinhaltes durch die schräg gestellten Rührblätter und eine gleichzeitige, intensive lokale Durchmischung von Flüssigkeiten/Flüssigkeiten und/oder Flüssigkeiten/Feststoffen durch die vertikalen Rührblätter. Das neuartige Rührelement hat eine hohe Effektivität und hohen Wirkungsgrad durch die intensive Umwälzung des Produkts und dadurch resultierende, ständige erneute Heranführung an die vertikalen Rührblätter zur intensiven Verwirbelung. Dies bedeutet in der Praxis eine Verkürzung der Mischzeit, und Energieeinsparung.Stirring element with 2x2 or 3x3 inclined and straight blades. The advantage of the new stirring element is characterized by intensive circulation of the contents of the container through the inclined stirring blades and simultaneous, intensive local mixing of liquids/liquids and/or liquids/solids through the vertical stirring blades. The new stirring element is highly effective and efficient due to the intensive circulation of the product and the resulting constant re-approach to the vertical stirring blades for intensive swirling. In practice, this means a reduction in mixing time and energy savings.
