Abstract
Description
Die bisher verwendeten Rührwerke sind mit radialgedichteten oder magnetgekoppel ten Behälterdurchführungen, für die Rührwerkzeuge ausgerüstet. Radialgedichtete Rührwerke sind je nach verwendetem Medium starkem Verschleiß und Erhitzung ausgesetzt, welchem durch hohen technischen Aufwand, wie Schmieren, Kühlen der Spülen entgegengewirkt wird.The agitators used so far are with radially sealed or magnetically coupled th tank bushings, equipped for the stirring tools. Radial sealed Depending on the medium used, agitators are subject to severe wear and heating exposed, which due to high technical effort, such as lubrication, cooling the sink is counteracted.
Durch Abrieb der Radialdichtung kann das Medium verschmutzt werden. Bei Un dichtigkeiten durch Verschleiß kann es zu Schmier-, Kühl- oder Spülmittelverunreini gung des Mediums kommen.The medium can be contaminated by abrasion of the radial seal. At Un Leakage due to wear can lead to lubricant, coolant or detergent contamination the medium.
Magnetgekoppelte Behälterdurchführungen sind begrenzt in ihrer Übertragung grö ßerer Drehmomente und es muß Rücksicht auf die Lagerung innerhalb des Behäl ters genommen werden. Der Abrieb der Lagerung kann zur Verschmutzung des Mediums führen. Ein Festfressen der Lagerung durch nicht schmierfähige Medien kann zum Stillstand des Rührwerks führen.Magnetically coupled tank bushings are limited in their transmission size lower torques and it must take into account the storage within the container be taken. The abrasion of the storage can contaminate the Lead medium. A seizure of the bearing by non-lubricatable media can cause the agitator to stop.
Durch die Verwendung eines nicht drehenden, aber rotierenden Rührerrohrs bzw. Umhüllung (7), Fig. 1, in welches eine abgeknickte rotierende Rührerwelle (6), Fig. 1, eingeschlossen ist, wird ein guter Rühreffekt ohne die beschriebenen Nachteile er reicht.By using a non-rotating, but rotating stirrer tube or casing ( 7 ), Fig. 1, in which a kinked rotating stirrer shaft ( 6 ), Fig. 1, is included, a good stirring effect without the disadvantages described, it is sufficient.
Als Verbindung zwischen der festen Behälterwand (4) und dem Rührerrohr bzw. Umhüllung (7) wird als flexibles, dichtendes Element (3) ein Elastomer in Schlauch- oder Faltenbalgform aus Gummi, Silikon oder Kunststoff verwendet.As a connection between the fixed container wall ( 4 ) and the stirrer tube or casing ( 7 ), an elastomer in the form of a hose or bellows made of rubber, silicone or plastic is used as the flexible, sealing element ( 3 ).
Auch eine metallische Verbindung durch einen Faltenbalg ist möglich. A metallic connection through a bellows is also possible.
Die Lagerung der Knickwelle (6) im Rührerrohr bzw. Umhüllung (7) kann beispiels weise durch Gleit-, Kugel- oder Rollenlager realisiert werden.The storage of the articulated shaft ( 6 ) in the stirrer tube or casing ( 7 ) can be realized, for example, by sliding, ball or roller bearings.
Die Lagerung an der Antriebsseite der Knickwelle kann ebenfalls in verschiedenen Lagerarten ausgeführt werden. Das Wellenende (2) kann aber z. B. auch direkt in dem Futter eines handelsüblichen Rührwerksantriebes befestigt werden, unter Ver zicht der Lagerung.The bearing on the drive side of the articulated shaft can also be carried out in different types of bearings. The shaft end ( 2 ) can, for. B. can also be attached directly to the feed of a standard agitator drive, without storage.
Die Beispiele der Ausführung des Rührrohrprofils bzw. Umhüllungsprofils, Fig. 2, in Ovalform (11), drei- (10), vier- (9) oder mehreckiger (8) Ausführung bewirken eine Steigerung des Rühreffekts.The examples of the design of the stirring tube profile or cladding profile, FIG. 2, in oval shape ( 11 ), three- ( 10 ), four- ( 9 ) or polygonal ( 8 ) design bring about an increase in the stirring effect.
Durch den Anbau von festen Flügeln, wie in Fig. 3 oder Fig. 4 dargestellt wird, kann der Rühreffekt weiter gesteigert werden.The stirring effect can be further increased by the attachment of fixed wings, as shown in FIG. 3 or FIG. 4.
Der Rührflügeleinsatz, Fig. 5, kann statt eines magnetgekoppelten Rührwerks bei hochviskosen Medien eingesetzt werden, da hohe Drehmomente übertragbar sind.The agitator blade insert, FIG. 5, can be used instead of a magnetically coupled agitator for highly viscous media, since high torques can be transmitted.
Das Anbringen von Zu- und Abgabevorrichtungen (16), Fig. 6, sowie das Aufstecken von Belüfterhülsen (17), Fig. 6, aber auch das Befestigen von Sensoren (18), Fig. 6, ist einfach durchführbar. Die Zuleitungen, z. B. Schläuche oder Kabel, können direkt durch die Behälterwand geführt werden. Da das Rührerrohr bzw. die Umhüllung selbst keine Drehbewegung ausführt, ist ein Wickeln ausgeschlossen.The attachment of dispensing and dispensing devices ( 16 ), Fig. 6, as well as the fitting of aerator sleeves ( 17 ), Fig. 6, but also the attachment of sensors ( 18 ), Fig. 6, can be carried out easily. The feed lines, e.g. B. hoses or cables can be passed directly through the container wall. Since the stirrer tube or the casing itself does not perform any rotational movement, winding is impossible.
Die Belüftung, siehe Teil (17), ist viel intensiver durch die Schwenkbewegung als bei einer starr angebrachten Belüftungsvorrichtung.The ventilation, see part ( 17 ), is much more intensive due to the pivoting movement than with a rigidly attached ventilation device.
Bei Zugabe von Medien, siehe Teil (16), werden diese sofort mit der Behälterfüllung vermischt, ebenso wird bei Abnahme von Material eine repräsentative Probe gezo gen.If media are added, see part ( 16 ), they are immediately mixed with the container filling, and a representative sample is also drawn when material is removed.
Durch Änderung der Antriebsdrehzahl kann an einem angebauten Sensor, siehe Teil (18), die erforderliche Anströmung innerhalb des Mediums eingestellt werden.By changing the drive speed, the required inflow within the medium can be set on an attached sensor, see part ( 18 ).
Das Wickeln von faserigem Material um das Rührerrohr bzw. die Umhüllung erfolgt nicht, da dieses keine Drehbewegung ausführt. Fibrous material is wrapped around the stirrer tube or casing not because it does not rotate.
Eine weitere Variante wäre die Doppelrührerrohrausführung wie in Fig. 7, welche gleich- oder gegenläufig angetrieben werden können. Aber auch eine größere An zahl von Rührerrohren, verteilt innerhalb eines Behälters, wären möglich.Another variant would be the double stirrer tube design as in FIG. 7, which can be driven in the same or opposite directions. But a larger number of stirrer tubes, distributed within a container, would also be possible.
Der Anbau eines oder mehrerer Rührwerke kann an jeder beliebigen Stelle eines Behälters erfolgen, wie seitlich, oben oder unten.One or more agitators can be attached at any point Containers are made like the side, top or bottom.
