Description

Die Erfindung betrifft eine Mahlvorrichtung mit einer Mühle als Einbaumodul in ein Behältnis, insbesondere ein Filter oder Silo, nach dem Oberbegriff des Anspruchs 1.The invention relates to a grinding device with a mill as a built-in module in a container, in particular a filter or silo, according to the preamble of claim 1.

Stand der TechnikState of the art

Mahlvorrichtungen mit Mühlen unterschiedlichster Art sind bekannt. Sie bestehen aus Produktaufgabe, Mühle, Produktabscheider und Gebläse. Manche Produkte erfordern einen hohen Luftvolumenstrom zur Kühlung des Produktes während der Mahlung, diese Anlagen werden im Durchluftbetrieb gefahren. Andere Produkte sind weniger temperaturempfindlich und können ohne kühlenden Luftstrom verarbeitet werden. Zur Unterstützung des Materialtransportes kann bei diesen Produkten die Luft im Kreislauf geführt werden. Vorteil dieser Lösung ist, dass aufwändige Produktabscheider wie Zyklone oder Filter entfallen. Die DE 9300910 U1 beschreibt eine Anlage zur Mahlung von Zucker. Hier ist eine Mühle direkt auf einem Behälter angeordnet. Das gemahlene Produkt wird danach in diesem Auffangtrichter zum Austrag geführt. In diesem Beispiel wird Luft in einem Kreislauf durch die Mühle gefahren, wobei die Luft aus dem Auffangtrichter abgezogen und vor die Mühle in den Produkteinlauf zugeführt wird.Grinding devices with mills of various kinds are known. They consist of product task, mill, product separator and blower. Some products require a high air volume flow to cool the product during grinding, these systems are operated in Durchluftbetrieb. Other products are less sensitive to temperature and can be processed without cooling airflow. To support the material transport, the air in these products can be recirculated. The advantage of this solution is that expensive product separators such as cyclones or filters are eliminated. The DE 9300910 U1 describes a plant for grinding sugar. Here a mill is arranged directly on a container. The ground product is then led to the discharge in this collecting funnel. In this example, air is circulated through the mill, the air being withdrawn from the hopper and fed into the product inlet before the mill.

Die DE 693 24 147 T2 offenbart eine Granuliermühle mit einem Cutter der aus einem Sammelbehälter gespeist wird und der über einem Granulatbehälter angeordnet ist, welcher das zerkleinerte Produkt aufnimmt. Der Cutter, der Sammelbunker und der Granulatbehälter sind über zwei Schwenkeinrichtungen miteinander verbunden und können über diese geöffnet werden, sodass der Cutter und der Granulatbehälter zugänglich werden.The DE 693 24 147 T2 discloses a granulating mill with a cutter fed from a sump and disposed above a granule container receiving the comminuted product. The cutter, the collection bunker and the granulate container are connected to each other via two pivoting devices and can be opened via these, so that the cutter and the granule container are accessible.

Die DE 25 44 496 A1 offenbart eine Schneidmühle, deren Gehäuse aus einem Ober- und Unterteil besteht wobei der Rotor im Oberteil gelagert ist. Das Oberteil ist über eine zur Rotorachse parallele Achse klappbar mit dem Unterteil verbunden.The DE 25 44 496 A1 discloses a granulator whose housing consists of an upper and lower part wherein the rotor is mounted in the upper part. The upper part is hingedly connected to the lower part via an axis parallel to the rotor axis.

Die DE 16 79 862 A1 zeigt ebenfalls eine Schneidmühle, dessen Gehäuseober- und Unterteil über eine zur Rotorachse parallele Achse klappbar miteinander verbunden ist.The DE 16 79 862 A1 also shows a cutting mill, the housing upper and lower part is hinged together via an axis parallel to the rotor axis.

Die DE 10 2006 021 196 B3 offenbart Mühlen oder Sichter die so ausgeführt sind, dass das Mühlen- oder Sichtergehäuse über eine Achse mit einem Magnetlagerspindelgehäuse verbunden ist und durch wegklappen des Mühlen- oder Sichtergehäuses die Mahlwerkzeuge oder das Sichtrad frei gibt.The DE 10 2006 021 196 B3 discloses mills or classifiers that are configured so that the mill or classifier housing is connected via an axis to a magnetic bearing spindle housing and, by folding away the mill or classifier housing, releases the grinding tools or the indexing wheel.

Aufgabetask

Aufgabe der Erfindung ist es eine Mahlvorrichtung der eingangs genannten Art zu schaffen, die kompakt und Kosten sparend aufgebaut ist, leicht zu Handhaben ist und bei explosionsfähigen Produkten auch leicht an die Anforderungen der einschlägigen Explosionsschutz-Richtlinien angepasst werden kann.The object of the invention is to provide a grinding device of the type mentioned, which is compact and cost-saving, easy to handle and can be easily adapted to explosive products to the requirements of the relevant explosion protection guidelines.

Lösungsolution

Diese Aufgabe wird durch eine Mahlvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Die erfindungsgemäße Mahlvorrichtung besteht aus einer Mühle, die derart ausgebildet ist, dass sie in eine Öffnung eines Behältnisses eingesteckt und in dieser Position betrieben werden kann. Das Behältnis übernimmt die Funktion des Mühlengehäuses. Dadurch entfällt das eigentliche Mühlengehäuse.This object is achieved by a grinding apparatus having the features of claim 1. Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims. The grinding device according to the invention consists of a mill, which is designed such that it can be inserted into an opening of a container and operated in this position. The container assumes the function of the mill housing. This eliminates the actual mill housing.

Beschreibung der ErfindungDescription of the invention

Die Mahlvorrichtung besteht aus Mühle in Modulbauweise und einem Behältnis einer verfahrenstechnischen Anlage. Das Behältnis in welches die Mühle eingebaut werden soll, weist eine Öffnung mit Flansch und Scharnierlager auf. Diese Öffnung ist ein Mannloch, das für Wartungszwecke vorgesehen ist. Der Deckel für diese Öffnung ist erfindungsgemäß als Mühlenfunktionsteil gestaltet.
Der Deckel mit Mühlenfunktionsteilen ist mit einem Deckelscharnier im Scharnierlager schwenkbar gekoppelt, so dass die Mühle aus dem Behältnis herausgeschwenkt werden kann. Der Deckel lässt sich mit Verbindungselementen verschließen und hält die Mühle in betriebssicherer Position.
Die Mühle ist folgendermaßen in den Verschlussdeckel eingebaut. Auf der einen Seite der Deckelplatte befindet sich der Antrieb für den Rotor der Mühle. Die Welle wird durch die Deckelplatte geführt. Auf der Innenseite ist das Mahlwerkzeug an den Rotor angebracht und der Stator fixiert. Im oberen Teil des Verschlussdeckels ist der Mühleneinlauf d.h. der Produkteinlauf angeordnet.
Als Mühle kann z.B. eine Prallmühle mit Stiftscheibenmahlwerk gewählt werden. Das Behältnis in das die Mühle eingebaut wird, kann ein Filter sein, aber auch ein Silo.
Bei der erfindungsgemäßen konstruktiven Lösung lässt sich so das eigentliche Mühlengehäuse sparen. Die Funktionsteile der Mühle, nämlich Antrieb, Welle, Rotor, Stator und Produkteinlauf werden an den Deckel montiert und als Modul in ein Behältnis mit Öffnung, z.B. ein Filter eingesteckt und der Deckel wird fest mit dem Flansch der Öffnung verbunden.
Erfindungsgemäße Mahlsysteme können ohne Luftstrom durch die Mühle, mit Umluft oder auch mit Durchluft ausgeführt werden.The grinding device consists of a modular mill and a container of a process plant. The container in which the mill is to be installed has an opening with flange and hinge bearing. This opening is a manhole intended for maintenance purposes. The lid for this opening is designed according to the invention as a mill function part.
The lid with mill functional parts is pivotally coupled with a lid hinge in the hinge bearing, so that the mill can be swung out of the container. The lid can be closed with fasteners and keeps the mill in a reliable position.
The mill is installed in the cap as follows. On one side of the cover plate is the drive for the rotor of the mill. The shaft is guided through the cover plate. On the inside, the grinding tool is attached to the rotor and the stator is fixed. In the upper part of the cap, the mill inlet ie the product inlet is arranged.
As a mill, for example, an impact mill can be selected with Stiftscheibenmahlwerk. The container in which the mill is installed, can be a filter, but also a silo.
In the constructive solution according to the invention, the actual mill housing can thus be saved. The functional parts of the mill, namely drive shaft, rotor, stator and product inlet are mounted on the lid and inserted as a module in a container with opening, such as a filter and the lid is firmly connected to the flange of the opening.
Inventive Mahlsysteme can be performed without air flow through the mill, with circulating air or through air.

Vorteile der ErfindungAdvantages of the invention

Vorteile der Erfindung ergeben sich daraus, dass das Mühlengehäuse und somit ein Kosten intensives Bauteil entfällt. Einsparungen ergeben sich besonders bei druckfesten Anlagen. Es entfallen außerdem die verbindenden Rohrleitungen zwischen Mühle und nachfolgenden Anlagenkomponenten.Advantages of the invention result from the fact that the mill housing and thus a cost intensive component is eliminated. Savings are particularly evident in pressure-resistant systems. It also eliminates the connecting pipes between the mill and subsequent plant components.

Diese konstruktive Gestaltung von Mahlvorrichtungen lässt sich vorteilhaft für die Mahlung von Zucker einsetzten. Fein gemahlener Zucker gehört zu den explosionsfähigen Produkten das Mahlsystem muss daher gegen Explosionen geschützt werden. Zucker ist nicht temperaturempfindlich, daher ist die Verarbeitung ohne kühlenden Luftstrom möglich.This constructive design of grinding devices can be used advantageously for the grinding of sugar. Finely ground sugar is one of the explosive products, the grinding system must therefore be protected against explosions. Sugar is not sensitive to temperature, therefore processing without cooling air flow is possible.

Die Erfindung stellt eine kostengünstige Möglichkeit der Nachrüstung von Anlagen mit Mühlen dar, da bestehende Anlagenteile weiter genutzt werden und das eigentliche Mühlengehäuse entfällt. Außerdem ist ein einfacher Einbau der nachzurüstenden Maschine durch Anflanschen der Mühle am Mannloch möglich.The invention represents a cost-effective way of retrofitting systems with mills, since existing plant parts are still used and the actual mill housing deleted. In addition, a simple installation of the machine to be retrofitted by flanging the mill on the manhole is possible.
