Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Mahlen, Mischen oder Dispergieren von niedrig- bis hochviskosen Suspensionen mit einem Behälter in dem ein rotierendes Werkzeug angeordnet ist und zwischen einem stehenden und einem rotierenden Werkzeugteil eine Gleitringdichtung sitzt.The The invention relates to a device for grinding, mixing or dispersing from low to high viscosity suspensions with a container in the a rotating tool is arranged and between a standing and a rotating tool part has a mechanical seal.
In der Praxis kommen entsprechende Vorrichtungen zum Einsatz, die einen Reaktionsbehälter aufweisen, in den ein sogenannter Mahlkorb in unterschiedlichster Bauweise eintaucht, um die darin befindliche Suspension zu bearbeiten. Die zwischen dem rotierenden Mahlkorb und der Lagerung eingesetzte Gleitringdichtung wird lagerungsseitig mit einer Sperrflüssigkeit beaufschlagt, die unter Druck oder drucklos betrieben werden kann. Das dazu notwendige Sperrflüssigkeitsvolumen wird nur in bestimmten Intervallen während des Stillstandes der Vorrichtung überprüft.In In practice, appropriate devices are used, one Have reaction vessels, in a so-called grinding basket in various designs immersed to process the suspension therein. The Mechanical seal inserted between the rotating grinding basket and the bearing is loaded with a barrier liquid on the storage side can be operated under pressure or without pressure. The necessary Barrier fluid volume is only checked at certain intervals while the device is at a standstill.
Die Aufgabe der vorliegenden Erfindung liegt darin, die Betriebssicherheit der Vorrichtung auch während der Produktionsphase zu verbessern.The The object of the present invention is operational reliability the device also during to improve the production phase.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention Object achieved by the features of claim 1.
Vorteilhafte Weitergestaltungen gehen aus den Merkmalen der Unteransprüche hervor.advantageous Further developments emerge from the features of the subclaims.
Eine erste vorteilhafte Ausgestaltung der Erfindung bezieht sich darauf, daß der Mahlkorb in dem Mahl-, Misch- oder Dispergierwerkzeuge angeordnet sind, selbst rotiert. Hierbei bildet die rotierende Hohlwelle und die stehende Welle, die mit dem/n Werkzeugen verbunden ist, einen ringzylindrischen Kanal, der über mindestens eine Bohrung in der rotierenden Welle mit dem Vorratsraum für die Sperrflüssgkeit in Verbindung steht.A first advantageous embodiment of the invention relates to that the Grinding basket in which grinding, mixing or dispersing tools are arranged, itself rotates. Here, the rotating hollow shaft and the standing shaft, which is connected to the tool (s), an annular cylindrical Channel that over at least one hole in the rotating shaft with the storage space for the Sperrflüssgkeit communicates.
In einer zweiten Ausgestaltung der Erfindung ruht der Mahlkorb, so daß auch die Hohlwelle nicht rotiert. Die Verbindung des ringzylindrischen Kanals, der an die Gleitringdichtung anschließt, mit dem Vorratsraum, besteht deshalb über die Bohrungen in der starren Hohlwelle.In According to a second embodiment of the invention, the grinding basket rests that too the hollow shaft does not rotate. The connection of the ring cylindrical Channel that connects to the mechanical seal with the storage space therefore about the holes in the rigid hollow shaft.
Entsprechend einer weiteren erfindungsgemäßen Ausgestaltung der Erfindung weist der Vorratsraum eine Füllstandsüberwachung auf, die die Menge der vorhandenen Sperrflüssigkeit angibt. Hierzu kommt eine optische Einheit zum Einsatz. Das dafür vorgesehene durchsichtige Meßröhrchen besitzt eine Skala von der der aktuelle Wert der vorhandenen Sperrflüssigkeitsmenge während des Betriebes der Vorrichtung vom Wartungs- oder Bedienungspersonal entnommen werden kann. Damit wird die Gefahr verringert, daß die Gleitringdichtung mangels ausreichender Menge an Sperrmittel heißläuft und möglicherweise sogar Explosionsgefahr besteht.Corresponding a further embodiment of the invention According to the invention, the storage room has a fill level monitor that measures the quantity the existing barrier liquid indicates. An optical unit is used for this. The intended one has transparent measuring tubes a scale from which the current value of the existing barrier fluid quantity while the operation of the device by maintenance or operating personnel can be removed. This reduces the risk that the mechanical seal overheating due to a lack of sufficient amount of blocking agent and possibly even risk of explosion consists.
Entsprechend einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Vorratsraum mindestens einen Niveauschalter auf, der im Bereich dessen Bodens sitzt und dann, wenn der Schwimmer einen Minimalwert der Sperrflüssigkeitsmenge darstellt, ein Signal abgibt. Zusätzlich oder getrennt zur Überwachung der Sperrflüssigkeitsmenge kann erfindungsgemäß auch die Temperatur des Sperrmittels gemessen werden, indem der Vorratsraum ein Thermometer aufweist.Corresponding Another advantageous embodiment of the invention, the Storage room at least one level switch in the area of Bottom and then when the float reaches a minimum value Barrier fluid amount represents, emits a signal. Additionally or separately for monitoring the amount of sealing liquid can also according to the invention Temperature of the locking agent can be measured by the storage room has a thermometer.
Durch die Verbindung der Überwachungseinrichtung (z.B. Niveauschalter, Thermometer) mit einer Steuerung, die die Meßergebnisse auswertet, kann die Betriebssicherheit der Vorrichtung erhöht werden. Dabei wird anhand der ermittelten Meßwerte eine Steuerung verschiedener Betriebsparameter, wie z.B. Drehzahl des Werkzeugs, Kühlung der Sperrflüssigkeit, Nachfüllung der Sperrflüssigkeit, Veränderung der Eintauchtiefe des Werkzeugs, ermöglicht. Beim Überschreiten einzelner Betriebsparameter kann auch ein akustisches Warnsignal erzeugt oder der Antrieb der Vorrichtung abgeschaltet werden.By the connection of the monitoring device (e.g. level switch, thermometer) with a controller that controls the Measurement results evaluates, the operational safety of the device can be increased. A control of different is based on the determined measured values Operating parameters such as Speed of the tool, cooling of the sealing liquid, refill the barrier liquid, change the immersion depth of the tool. When crossing individual operating parameters can also be an acoustic warning signal generated or the drive of the device can be switched off.
Die Erfindung wird anhand eines schematischen Ausführungsbeispiels beschrieben. Es zeigt:The The invention is described on the basis of a schematic exemplary embodiment. It shows:
