Description

Die Erfindung betrifft eine Mühle zum Mahlen von Getreide gemäß dem Oberbegriff des Anspruchs 1. Zum Mahlen von Mahlgut insbesondere Getreide zur Herstellung von Mehl sind verschiedenartige Mühlen bekannt. Neben traditionellen Steinmühlen werden auch Mühlen eingesetzt, bei denen die Mahlarbeit mittels eines Messersatzes geleistet wird, der in einem Mahlwerk rotiert und das Mahlgut direkt bzw. mittels Auftreffen auf eine Prallplatte zerkleinert. Eine derartige Mühle ist im deutschen Gebrauchsmuster DE 20 2004 005 117 beschrieben.The invention relates to a mill for grinding cereals according to the preamble of claim 1. For grinding millbase, in particular cereals for the production of flour, various types of mill are known. In addition to traditional stone mills and mills are used in which the grinding is done by means of a knife set, which rotates in a grinder and crushed the ground material directly or by hitting a baffle plate. Such a mill is in German utility model DE 20 2004 005 117 described.

Aus dem Dokument US 3 090 568 A ist eine Mühle zum Mahlen von Mahlgut bekannt, bei der das Mahlgut über eine Mahlgutzuführung ein Mahlwerk zugeführt wird und gemahlen über einen Auslass abgegeben wird. In dem Mahlwerk ist ein rotierender Messersatz angeordnet, der mehrere Messer aufweist die mittels eines Motors angetrieben werden. Die Messer verfügen umlaufend über Zähne, die mit Schneidplatten versehen sind.From the document US Pat. No. 3,090,568 a mill for grinding regrind is known, in which the millbase is fed via a Mahlgutzuführung a grinder and is discharged ground via an outlet. In the grinder, a rotating knife set is arranged, which has a plurality of blades which are driven by a motor. The knives have circumferential teeth which are provided with inserts.

Aufgabe der Erfindung ist es die Leistungsfähigkeit einer Mühle zum Mahlen von Getreide weiter zu erhöhen. Das heißt, es soll die Mahlleistung erhöht werden, um den Volumenstrom durch die Mühle bei möglichst nicht erhöhtem Stromverbrauch zu erhöhen und so die Effektivität der Maschine weiter zu verbessern. Dabei ist eine hinreichende Mahlgüte Vorrausetzung.The object of the invention is to further increase the efficiency of a mill for grinding cereals. This means that the grinding capacity should be increased in order to increase the volume flow through the mill with as little as possible increased power consumption and thus to further improve the effectiveness of the machine. In this case, a sufficient Mahlgüte is a prerequisite.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhaft sind die Messer scheibenartig ausgebildet und die Schneidplatten so an den Zähnen der Messer angeordnet, dass deren Oberfläche im rechten Winkel zur Scheibenebene steht.This object is solved by the features of claim 1. Advantageously, the blades are formed like a disk and the inserts are arranged on the teeth of the knife so that their surface is at right angles to the disk plane.

Auch eine leichte Neigung der Schneidplatten gegenüber dieser Ebene ist vorteilhaft möglich. Dabei sind die Schneidplatten vorteilhaft gegenüber dem Radius der Scheibe geneigt angeordnet und mit der Oberkante in Rotationsrichtung nach vorne gekippt. Vorteilhaft sind die Schneidplatten, wie bereits dargelegt, aus einem Material gefertigt, das ein Schleifen derselben bzw. ein Nachschleifen ermöglicht. Hierzu haben sich Vidiaplatten bewährt.Also, a slight inclination of the inserts relative to this plane is advantageously possible. The cutting plates are advantageously arranged inclined relative to the radius of the disc and tilted with the upper edge in the direction of rotation to the front. Advantageously, the cutting plates, as already explained, made of a material that allows grinding same or a regrinding. For this purpose, Vidiaplatten have proven.

Bewährt hat sich weiterhin ein Design bei dem die Schneidplatten etwa doppelt so breit sind wie die Scheiben der Messer stark sind. Die hohe Mahlleistung derartiger Messer kann je nach Mahlgut leicht zu einem Blockieren des Messersatzes führen. Dies wird mit der dargelegten Dimensionierung vermieden, da durch die Messerscheiben, die eine geringere Stärke aufweisen, gewissermaßen radial innerhalb der Schneidplatten Platz geschaffen wird, in dem sich das gemahlene Mahlgut bewegen kann und somit ein Blockieren der Messer weitestgehend verhindert wird. Bewährt hat sich dabei eine Stärke der Messer von etwa 2mm und eine Schneidplattenbreite von etwa 4mm. Ebenso hat sich eine Anordnung mit zwölf bis vierzehn Messern im Mahlraum bewährt. Dabei werden die Messer vorteilhaft direkt auf der Antriebswelle montiert und drehfest mit dieser beispielsweise über eine Keilnutenverbindung verbunden. Ein Versetzen der Messer derart, dass die Zähne der Messer nicht fluchten ist nicht erforderlich. Vielmehr hat sich bei fluchtender Montage auf der Antriebswelle eine hervorragende Mahlleistung gezeigt. Aufgrund der Tatsache, dass die Messer schmäler ausgeführt sind als die Schneidplatten, müssen die Messer mit einem bestimmten Abstand auf der Antriebswelle montiert werden. Hierzu haben sich Distanzscheiben bewährt, die beim konkreten Ausführungsbeispiel 4 bzw. 5mm stark sind.Another proven design is that the inserts are about twice as wide as the discs of the knives are strong. Depending on the material to be ground, the high grinding performance of such knives can easily lead to blockage of the knife set. This is avoided with the stated dimensioning, as is created by the blade wheels, which have a lower thickness, so to speak radially within the inserts space in which the ground millbase can move and thus blocking the knife is largely prevented. A strength of the knives of about 2mm and an insert width of about 4mm has proven to be useful. Likewise, an arrangement with twelve to fourteen knives in the grinding chamber has proven itself. The blades are advantageously mounted directly on the drive shaft and rotatably connected thereto, for example via a keyway connection. A displacement of the knife so that the teeth of the knife is not aligned is not required. Rather, an excellent grinding performance has been shown in aligned mounting on the drive shaft. Due to the fact that the knives are made narrower than the inserts, the knives must be mounted with a certain distance on the drive shaft. For this purpose, spacers have proven that 4 or 5mm are strong in the specific embodiment.

Bewährt hat sich die Montage des Motors direkt am Gehäuse des Mahlwerks. Hierdurch werden Vibrationen unterdrückt und insgesamt eine steifere Konstruktion geschaffen, die weniger dazu neigt in Schwingung zu geraten, auch wenn durch die Mahlarbeit das System zu Schwingungen angeregt wird. Wenngleich hier typischerweise verwendete Elektromotoren über eine Wellendichtung verfügen, hat sich gezeigt, dass die auf diese Weise realisierte Abdichtung der Welle insbesondere bei Mahlgut, das Feinstaub entstehen lässt, nicht ausreichend ist. Vorteilhaft wird die Welle des Antriebsmotors daher durch eine weitere spezielle Wellendichtung gegenüber dem Innenraum des Mahlwerks abgedichtet. Diese zusätzliche Wellendichtung kann mittels eines Zusatzflansches angeordnet werden, der am Motor befestigbar ist. Vorteilhaft wird hierzu am Motorgehäuse ein Zusatzflansch verschraubt, der die genannte weitere Wellendichtung aufnimmt.The assembly of the motor has proven itself directly on the housing of the grinder. As a result, vibrations are suppressed and created overall a stiffer construction, which is less likely to vibrate, even if the grinding is stimulated by the system to vibrate. Although here typically used electric motors have a shaft seal, it has been shown that the realized in this way sealing of the shaft is not sufficient, especially with regrind, the fine dust is created. Advantageously, the shaft of the drive motor is therefore sealed by a further special shaft seal with respect to the interior of the grinder. This additional shaft seal can be arranged by means of an additional flange which can be fastened to the engine. Advantageously, an additional flange is bolted to the motor housing, which receives the said further shaft seal.

Vorteilhaft ist der Motor mit einer Motorsteuerung versehen, die ein langsames Hochfahren des Motors auf die Solldrehzahl ermöglicht. Das bei Elektromotoren übliche schnelle Hochfahren des Motors führt insbesondere in Verbindung mit dem beschriebenen leistungsstarken Messersatz zu einer starken mechanischen Beanspruchung der Mühle, insbesondere des Mahlwerks, durch das Auftreten unerwünschter Vibrationen. Dies kann durch ein langsames Hochfahren des Motors vermieden werden.Advantageously, the engine is provided with a motor control, which allows a slow start-up of the engine to the target speed. The usual in electric motors rapid startup of the engine leads, especially in conjunction with the described powerful blade set to a strong mechanical stress on the mill, especially the grinder, by the Occurrence of unwanted vibrations. This can be avoided by slowly starting the engine.

Das Mahlgut wird vorteilhaft von oben über einen Trichter dem Mahlwerk zugeführt. In diesem Trichter können Magnete vorgesehen sein, die die Aufgabe haben, eventuell im Mahlgut befindliche metallische Gegenstände zurückzuhalten, um so Beschädigungen des Messersatzes zu vermeiden.The material to be ground is advantageously fed from above via a hopper to the grinder. In this funnel magnets can be provided, which have the task to retain any metallic objects located in the material to be ground so as to avoid damage to the set of knives.

Vorteilhaft ist der Auslass für das gemahlene Mahlgut an der Unterseite des Mahlwerks vorgesehen. Wird der Auslass an der tiefsten Stelle des Innenraums des Mahlwerks angeordnet, wird das Austragen des gemahlenen Mahlguts zuverlässig ermöglicht.Advantageously, the outlet for the ground regrind is provided on the underside of the grinder. If the outlet is arranged at the lowest point of the interior of the grinder, the discharge of the ground material is reliably made possible.

Am Mahlwerk kann weiterhin ein Anschluss zum Einbringen eines Fluids, bevorzugt Luft, vorgesehen sein, das in das Mahlwerk eingeblasen werden kann, um eine Überlagerung der Strömung des Mahlguts mit einer zweiten Fluidströmung zu erzielen, was sich insbesondere bei sehr dichten Mahlgut vorteilhaft auf das Mahlergebnis auswirkt. Der Anschluss zum Einbringen dieses Fluids kann seitlich oberhalb des Messersatzes vorgesehen sein, sodass die Strömung etwa im rechten Winkel auf die Mahlgutströmung auftrifft.The grinder can further be provided with a connection for introducing a fluid, preferably air, which can be blown into the grinder in order to achieve a superposition of the flow of the ground material with a second fluid flow, which is advantageous in particular for very dense material to be ground on the grinding result effect. The connection for introducing this fluid may be provided laterally above the blade set, so that the flow impinges on the ground material flow at approximately right angles.

Zweckmäßig ist das Mahlwerk mit einer verriegelbaren Klappe versehen, die es erlaubt den Innenraum des Mahlwerks zu inspizieren und gegebenenfalls doch auftretende Blockaden zu beheben. Vorteilhaft ist diese Klappe in der Nähe des Messersatzes angeordnet.Conveniently, the grinder is provided with a lockable flap, which allows to inspect the interior of the grinder and, where appropriate, to eliminate occurring blockages. Advantageously, this flap is arranged in the vicinity of the knife set.

Die in Fig. 2 nicht ersichtliche Welle des Antriebsmotors 2 ragt in den Innenraum des Mahlwerks und ist dort direkt mit den Messern 11 des Messersatzes 9 verbunden.In the illustration according to Fig. 2 the mill is shown with open grinder. For this purpose, the shown wall of the grinder housing 1 opened by means of a flap 8, so that the blade set 9 is visible. The flap 8 is pivotally mounted on a bolt 10 and locked on a non-explained control mechanism on the grinder housing 1. In the Fig. 2 not visible shaft of the drive motor 2 protrudes into the interior of the grinder and is there directly connected to the blades 11 of the blade set 9.

In Fig. 3 ist ein Messer 11 der erfindungsgemäßen Mühle dargestellt. Dieses Messer 11 weist eine scheibenartige Gestalt mit vier großen Ausnehmungen auf und ist im zentralen Bereich mit weiteren Ausnehmungen 14 versehen, die eine drehfeste Montage an der Welle des Antriebsmotors 2 ermöglichen. Am äußeren Umfang ist das Messer 11 mit Zähnen 13 versehen. Die in Rotationsrichtung vorneliegende Flanken sind mit Schneidplatten 15 versehen. Die Zähne 13 und auch die Schneidplatten 15 sind dabei gegenüber dem Radius des Messers 11 in Rotationsrichtung leicht nach vorne geneigt. Der scheibenartige Grundkörper des Messers 11 weist eine Stärke von 2mm auf, wohingegen die Schneidplatten 15 eine Breite in axialer Richtung des Messers 11 bzw. in Richtung der Antriebswelle des Antriebsmotors 2 von 4mm aufweist. Die Schneidplatten 15 sind aus einem schleifbaren bzw. nachschleifbaren Stahl hergestellt, sodass eine hohe Schärfe des Messers 11 gewährleistet werden kann.In Fig. 3 a knife 11 of the mill according to the invention is shown. This knife 11 has a disk-like shape with four large recesses and is provided in the central region with further recesses 14 which allow a rotationally fixed mounting on the shaft of the drive motor 2. At the outer periphery of the knife 11 is provided with teeth 13. The flanks protruding in the direction of rotation are provided with cutting plates 15. The teeth 13 and also the cutting plates 15 are slightly inclined relative to the radius of the blade 11 in the direction of rotation to the front.

Fig. 4 ersichtlich, den gewünschten Abstand zwischen den Messern 11 gewährleisten. In Fig. 4 sind die Messer 11 vereinfacht als Scheiben dargestellt. Die Schneidplatten 15 sind nicht dargestellt. Da zwölf Messer 11 zum Einsatz kommen, müssen elf Distanzscheiben 16 verwendet werden. Beim konkreten Ausführungsbeispiel weisen jeweils drei äußere Distanzscheiben 16a des Messersatzes 9 eine Stärke von 5mm auf, wobei die im mittleren Bereich des Messersatzes 9 eingesetzten fünf Distanzscheiben 16b eine Stärke von 4mm aufweisen. Weiterhin wird zum Abschluss, also rechts bzw. links des äußersten Messers, ebenfalls eine 4mm starke Abschlußscheibe 16c montiert. Eine derartige Anordnung und Variation des Messerabstandes hat sich bewährt und zu sehr guten Mahlergebnissen geführt. Fig. 4 can be seen to ensure the desired distance between the blades 11. In Fig. 4 the blades 11 are shown simplified as discs. The cutting plates 15 are not shown. Since twelve knives 11 are used, eleven shims 16 must be used. In the specific embodiment, three outer spacers 16a of the knife set 9 each have a thickness of 5 mm, wherein the five spacers 16b used in the central region of the knife set 9 have a thickness of 4 mm. Furthermore, at the end, ie right or left of the outermost knife, also a 4mm thick lens 16c mounted. Such an arrangement and variation of the knife distance has been proven and led to very good Mahlergebnissen.

Fig. 5 zeigt den Antriebsmotor 2 mit zusätzlicher Wellendichtung 17. Die zusätzliche Wellendichtung 17 wird mittels eines Zusatzflansches 18 montiert, der an einem Bund 19 des Gehäuses des Antriebsmotors 2 angeordnet ist. Bei dem hier konkreten Ausführungsbeispiel wird der Zusatzflansch 18 am Bund 19 verschraubt. Fig. 5 shows the drive motor 2 with additional shaft seal 17. The additional shaft seal 17 is mounted by means of an additional flange 18 which is arranged on a collar 19 of the housing of the drive motor 2. In the concrete embodiment, the additional flange 18 is screwed to the collar 19.

Fig. 6 zeigt den Mahlguttrichter 4 in dessen inneren Bereich beim Übergang in den Mahlguteinlass 5 stabförmige Magneten 20 montiert sind, die mittels eines Trägers 21 und Schrauben 22 im Innenraum des Mahlguttrichters 4 montiert sind. Mittels dieser Magnete 20 werden metallische Gegenstände, die zu einer Beschädigung der Messer 11 führen könnten, von dem Mahlwerk ferngehalten. Zum Entfernen der von den Magneten 20 aufgegriffenen metallischen Gegenstände kann der Träger 21 mit allen Magneten 20 komplett nach Lösen der Schrauben 22 entfernt werden. So können auf einfache Weise metallische Gegenstände von den Magneten 20 abgegriffen werden. Fig. 6 shows the grinding hopper 4 in the inner region of the transition into the Mahlguteinlass 5 rod-shaped magnets 20 are mounted, which are mounted by means of a carrier 21 and screws 22 in the interior of the grinding hopper 4. By means of these magnets 20 metallic objects, which could lead to damage of the blade 11, kept away from the grinder. To remove the metallic objects picked up by the magnets 20, the carrier 21 with all the magnets 20 can be completely removed after loosening the screws 22. Thus, metallic objects can be picked up by the magnets 20 in a simple manner.
