Description

Speisemodul für einen Walzenstuhl Feed module for a roller mill
Die Erfindung betrifft einen Speisemodul für einen Walzenstuhl, insbesondere einen Müllerei-Walzenstuhl zur Herstellung von Getreidemahlprodukten u. dgl. in Getreide- mühlen, Futtermühlen und anderen Mühlenbetrieben.The invention relates to a feed module for a roller mill, in particular a milling mill roller mill for the production of grain products and. The like. In grain mills, feed mills and other mill operations.
Walzenstühle zur Herstellung von Mahiprodukten, insbesondere bei der Vermahlung von Getreide weisen zumeist Speiseeinrichtungen mit Speisewalzen zur möglichst gleichmässigen Verteilung des zu mahlenden Gutes auf die gesamte Länge der Mahlwalzen auf. So beschreibt die EP-B-38054 eine Produkt-Speiseregelung, bei der Getreide aus einem Speiseraum auf eine Verteilwalze und eine Speise- bzw. Auflockerungswalze gelangt. Auf diese folgt ein Dosierschieber, der wiederum mit einem Signalgeber im Speiseraum verbunden ist, um mittels des Dosierschiebers einen Dosierspalt einzustellen. Der Zugang zu dieser Speiseeinrichtung ist sowohl über eine Kontrolltür als auch eine Kontrollklappe in begrenztem Masse gegeben. Um eine weitergehende Zugänglichkeit für Reinigungs- und Wartungszwecke zu erreichen, müssen diverse Verkleidungen u. a. entfernt werden. Weitere, z. B. in den DE-PS 2011783, DE-PS 240351 , DE-A-2462414 oder DE-A-3404732 beschriebenen Speiseeinrichtungen gehen über diesen Stand der Technik nicht hinaus.Roller mills for the production of mahogany products, in particular for the milling of cereals, mostly have feeding devices with feed rollers for distributing the material to be milled as evenly as possible over the entire length of the milling rollers. For example, EP-B-38054 describes a product feed control in which grain from a dining area passes onto a distribution roller and a feed or loosening roller. This is followed by a metering slide, which in turn is connected to a signal transmitter in the dining area in order to set a metering gap by means of the metering slide. To a limited extent, access to this feed device is provided via both a control door and a control flap. In order to achieve further accessibility for cleaning and maintenance purposes, various covers and a. be removed. More, e.g. B. feeding devices described in DE-PS 2011783, DE-PS 240351, DE-A-2462414 or DE-A-3404732 do not go beyond this prior art.
Der Erfindung liegt daher die Aufgabe zugrunde, die Speiseeinrichtung eines gat- tungsgemässen Müllerei-Walzenstuhles, z. B. gemäss DE-C-2730166 oder EP-B- 334919 so weiterzuentwickeln, dass bei einfachem und funktionssicherem Aufbau eine wesentliche Verbesserung der Sanitation und Zugänglichkeit erreicht werden. Diese Aufgabe wird an Hand der kennzeichnenden Merkmale des Anspruchs 1 gelöst. Die erfindungsgemässe Speiseeinrichtung ist als Speisemodul ausgebildet, der als ganze Baugruppe schwenkbar angeordnet ist. Hierbei sind die Speise- und die Verteilwalze in einem segmentförmigen Rahmen zusammen mit dem Dosierschieber und den entsprechenden Leitblechen aufgenommen. Der Rahmen ist um einen obenliegenden Drehpunkt schwenkbar angeordnet. Die Erfindung erlaubt darüber hinaus weitere, vorteilhafte Ausgestaltungen, die in den Unteransprüchen dargelegt sind. So ist es gleichfalls möglich, wenn auch an sich vorbekannt, gleichzeitig oder separat die übrigen Frontabdeckungen bzw. - Verkleidungen seitlich bzw. nach oben (vgl. WO 93/13857) schwenkbar zu gestalten. Ebenso können Dosier- und Leitbleche für das zu mahlende Produkt mit einer Vibro- dosierung versehen werden, wobei dann insbesondere der übliche Dosierschieber ersetzt wird.The invention is therefore based on the object, the feeding device of a generic milling mill roller z. B. according to DE-C-2730166 or EP-B-334919 so that with a simple and reliable construction a significant improvement in sanitation and accessibility can be achieved. This object is achieved on the basis of the characterizing features of claim 1. The feed device according to the invention is designed as a feed module which is pivotally arranged as a whole assembly. Here the feed and distribution rollers are accommodated in a segment-shaped frame together with the metering slide and the corresponding guide plates. The frame is pivotable about an overhead pivot point. The invention also allows further advantageous configurations, which are set out in the subclaims. Thus, it is also possible, although known per se, to simultaneously or separately design the other front covers or panels to be pivotable laterally or upwards (cf. WO 93/13857). Dosing and guide plates for the product to be ground can also be provided with a vibro dosing, in which case the usual dosing slide is replaced in particular.
Ergänzend hierzu ist eine an sich übliche Mahlspaltaspiration gemäss der DE-A- 2403351 so ausgebildet, dass Schleppluft über den Mahlwalzen gestoppt werden kann.In addition to this, a grinding gap aspiration, which is customary per se, is designed in accordance with DE-A-2403351 in such a way that drag air above the grinding rollers can be stopped.
