Abstract
Vorrichtung (10) zur Trocknung von Produkten, insbesondere Membranmodulen (6), mittels Mikrowellen, umfassend einen Vakuumbehälter (12) mit einem Anschluß (14) zum Anschließen einer Vakuumpumpe (7), einen in dem Vakuumbehälter (12) herausnehmbar angeordneten, steuerbar drehbaren Produkthalter (16), der in mindestens einer Ebene, vorzugsweise in äquidistanter Verteilung und/oder vorzugsweise in kreisförmiger Anordnung, mindestens zwei Produktaufnahmen aufweist, mindestens eine Mikrowellenerzeugungseinrichtung (3a) und mindestens eine Mikrowelleneinkoppeleinrichtung (3b) zum Einkoppeln der von der Mikrowellenerzeugungseinrichtung (3a) erzeugten Mikrowellen in den Vakuumbehälter (12), dadurch gekennzeichnet, daß der Vakuumbehälter (12) ein Unterteil (12a) und einen Deckel (12b) umfaßt, wobei der Deckel (12b) gemeinsam mit dem Produkthalter (16) abnehm- und aufsetzbar ist.Apparatus (10) for drying products, in particular membrane modules (6), by means of microwaves, comprising a vacuum container (12) with a connection (14) for connecting a vacuum pump (7), removably arranged in the vacuum container (12), controllably rotatable Product holder (16) which has at least two product receptacles in at least one plane, preferably in equidistant distribution and / or preferably in a circular arrangement, at least one microwave generating device (3a) and at least one microwave coupling device (3b) for coupling in the microwave generating device (3a) generated microwaves in the vacuum container (12), characterized in that the vacuum container (12) comprises a lower part (12a) and a lid (12b), wherein the lid (12b) together with the product holder (16) is removable and can be placed.
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Trocknung von Produkten, insbesondere Membranmodulen, mittels Mikrowellen gemäß dem Oberbegriff von Anspruch 1. Eine derartige Vorrichtung ist aus der
Eine Art der Trocknung von Filterelementen bzw. Membranmodulen besteht darin, die Filterelemente bzw. Membranmodule in Warmluftöfen zu trocknen, wobei diese Art der Trocknung den Flaschenhals in der Herstellung der Filterelemente darstellt. Die Umluftrocknung dauert nämlich mehrere Stunden bis Tage und die Abweichungen in der Trocknung im Vergleich der getrockneten Filterelemente sind oft zu groß.One type of drying filter elements or membrane modules is to dry the filter elements or membrane modules in hot air ovens, this type of drying is the bottleneck in the production of the filter elements. The circulating air drying lasts for several hours to days and the deviations in the drying compared to the dried filter elements are often too large.
Der Erfindung liegt somit die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art derart weiterzubilden, dass der Vakuumbehälter einfach be- und entladen werden kann.The invention is therefore based on the object, the device of the type mentioned in such a way that the vacuum container can be easily loaded and unloaded.
Erfindungsgemäß wird diese Ausgabe bei der Vorrichtung der eingangs genannten Art dadurch gelöst, dass der Vakuumbehälter ein Unterteil und einen Deckel umfasst, wobei der Deckel gemeinsam mit dem Produkthalter abnehm- und aufsetzbar ist.According to the invention, this output is achieved in the device of the type mentioned above in that the vacuum container comprises a lower part and a lid, wherein the lid can be removed and placed together with the product holder.
Die Produkte, wie z. B. Membranmodule, können in den Produktaufnahmen auch in einem verpackten Zustand, z. B. in einem Beutel, der eine Durchlässigkeit für Wasserdampf besitzt, wie zum Beispiel in einem Tyvek-Beutel, angeordnet werden.The products, such. B. membrane modules, in the product images in a packaged state, eg. In a bag having a permeability to water vapor, such as in a Tyvek bag.
Vorteilhafterweise ist die mindestens eine Mikrowelleneinkoppeleinrichtung in der mindestens einen Ebene der Produktaufnahmen angeordnet.Advantageously, the at least one microwave coupling device is arranged in the at least one plane of the product receptacles.
Besonders bevorzugt ist auf jeder Ebene der Produktaufnahme mindestens eine Mikrowelleneinkoppeleinrichtung angeordnet.Particularly preferably, at least one microwave coupling device is arranged on each level of the product receptacle.
Gemäß einer weiteren besonderen Ausführungsform der Erfindung sind in mindestens zwei Ebenen Produktaufnahmen vorgesehen und Paare von Produktaufnahmen in zwei benachbarten Ebenen zur gemeinsamen Aufnahme von einem Produkt gestaltet. Im Normalfall würde natürlich genau eine Produktaufnahme für genau ein Produkt verwendet.According to a further particular embodiment of the invention, product receptacles are provided in at least two levels, and pairs of product receptacles in two adjacent levels are designed for joint reception of a product. Normally, of course, exactly one product intake would be used for exactly one product.
Zweckmäßigerweise ist auf jeder Ebene der Produktaufnahme mindestens eine Temperaturüberwachungseinrichtung zur Überwachung der Temperatur der Produkte vorgesehen. Dies dient zur Vermeidung von Überhitzungen der Produkte.Conveniently, at least one temperature monitoring device for monitoring the temperature of the products is provided at each level of the product intake. This is to avoid overheating of the products.
Insbesondere kann dabei vorgesehen sein, dass die Temperaturüberwachungseinrichtung eine IR-Kamera ist.In particular, it can be provided that the temperature monitoring device is an IR camera.
Weiterhin ist zweckmäßigerweise eine Wägeeinrichtung zum Wiegen des Gewichts des Produkthalters mit in den Produktaufnahmen angeordneten Produkten vorgesehen. Über die Wägeeinrichtung kann anhand der mit der Trocknung verbundenen Gewichtsabnahme der Zeitpunkt ermittelt werden, zu dem der Trocknungsgrad den gewünschten Anforderungen entspricht, und nachfolgend die Trocknung z. B. automatisch beendet werden.Furthermore, a weighing device for weighing the weight of the product holder with products arranged in the product receptacles is expediently provided. About the weighing device can be determined based on the weight loss associated with the drying of the time at which the degree of drying meets the desired requirements, and then the drying z. B. be terminated automatically.
Selbstverständlich ist auch denkbar, dass anstelle des Deckels das Unterteil absenkbar ist, um an die Produkte in dem Produkthalter zu gelangen.Of course, it is also conceivable that instead of the cover, the lower part is lowered to get to the products in the product holder.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachstehenden Beschreibung, in der ein Ausführungsbeispiel anhand der schematischen Zeichnungen im einzelnen erläutert ist. Dabei zeigt:Further features and advantages of the invention will become apparent from the claims and the following description in which an embodiment with reference to the schematic drawings is explained in detail.
