Description

Mühle zum Mahlen von grobem, steinartigem Schüttgut mit achsparallelem AntriebMill for grinding coarse, stone-like bulk material with axis-parallel drive

Die vorliegende Erfindung betrifft eine Mühle zum Mahlen von grobem, steinartigem Schüttgut, beispielsweise Erz oder Kohle, mit einem um eine vertikale Drehachse drehbaren Mahlteller, wobei der Mahlteller mittels eines Elektromotors antreibbar ist, der eine Motorwelle mit einer Wellenachse aufweist.The present invention relates to a mill for grinding coarse, stone-like bulk material, for example ore or coal, with a grinding table rotatable about a vertical axis of rotation, wherein the grinding table is drivable by means of an electric motor having a motor shaft with a shaft axis.

Derartige Mühlen sind allgemein bekannt und werden beispielsweise von der Firma Polysius AG, Deutschland, unter den Typenbezeichnungen Dorol und Quadropol vertrieben. Ein Schaubild einer derartigen Mühle ist beispielsweise unter der Internet-Adresse http://www.polysius.com/imageneutraldetail-bild.asp?id=353 abrufbar.Such mills are well known and are sold for example by the company Polysius AG, Germany, under the type designations Dorol and Quadropol. A diagram of such a mill is available, for example, at the Internet address http://www.polysius.com/imageneutraldetail-bild.asp?id=353.

Die bekannte Mühle wird nachfolgend in Verbindung mit FIG 1 erläutert, soweit dies für das Verständnis der vorliegenden Erfindung erforderlich ist.The known mill is described below in connection with FIG. 1 as far as this is necessary for the understanding of the present invention.

Gemäß FIG 1 weist die Mühle einen Mahlraum 1 auf. Der Mahlraum 1 weist einen Mahlraumboden 2 und eine um den Mahlraum 1 umlaufende Mahlraumwand 3 auf. Auf dem Mahlraumboden 2 ist ein Mahlteller 4 derart gelagert, dass er um eine vertikale Drehachse 5 drehbar ist.According to FIG. 1 the mill has a grinding chamber 1 on. The grinding chamber 1 has a grinding chamber floor 2 and a milling space 3 surrounding the grinding chamber 1. On the Mahlraumboden 2 a grinding table 4 is mounted such that it is rotatable about a vertical axis of rotation 5.

Der Mahlteller 4 ist mittels eines Elektromotors 6 antreibbar. Der Elektromotor 6 weist eine Motorwelle 7 mit einer Wellenachse 8 auf.The grinding table 4 can be driven by means of an electric motor 6. The electric motor 6 has a motor shaft 7 with a shaft axis 8.

Im Stand der Technik ist bekannt, den Elektromotor 6 seitlich unter dem Mahlteller 4 anzuordnen. Rein beispielhaft wird auf die DE 33 02 049 A1 und die DE 35 07 913 A1 verwiesen.In the prior art it is known to arrange the electric motor 6 laterally below the grinding table 4. Purely by way of example is on the DE 33 02 049 A1 and the DE 35 07 913 A1 directed.

Die Wellenachse 8 verläuft in diesem Fall horizontal. Die Motorwelle 7 wirkt über ein Umlenk- oder Winkelgetriebe 9 - z. B. ein Kegelradgetriebe - auf den Mahlteller 4. Das Umlenkgetriebe 9 bewirkt zusätzlich zur Umlenkung eine Umsetzung von einer relativ hohen Drehzahl des Elektromotors 6 auf eine deutlich niedrigere Drehzahl des Mahltellers 4.The shaft axis 8 runs horizontally in this case. The motor shaft 7 acts via a deflection or bevel gear 9 - z. B. The bevel gear 9 causes in addition to the deflection of a conversion of a relatively high speed of the electric motor 6 to a much lower speed of the grinding table. 4

Dem Mahlraum 1 wird auf bekannte Weise - beispielsweise mittels einer nicht dargestellten Schüttrutsche - grobes, steinartiges Schüttgut 10 zugeführt, beispielsweise Kohle- oder Erzbrocken. Auf Grund der Zentrifugalkraft wird das Schüttgut 10 in Richtung auf die Mahlraumwand 3 nach radial außen geführt. Dort wird das Schüttgut 10 mittels Mahlwalzen 11 zermahlen, die auf dem Mahlteller 4 abrollen. Die Mahlwalzen 11 sind in der Regel nicht selbst angetrieben. Ein Antreiben der Mahlwalzen 11 wäre jedoch möglich. Das zermahlene Schüttgut - zur Unterscheidung vom ungemahlenen Schüttgut 10 als Mahlgut 12 bezeichnet - wird in bekannter Weise aus dem Mahlraum 1 abgeführt, beispielsweise mittels eines nicht dargestellten Gebläses.The grinding chamber 1 is in a known manner - for example by means of a Schuttrutsche not shown - coarse, stone-like bulk material 10, for example, coal or ore chunks. Due to the centrifugal force, the bulk material 10 is guided in the direction of the grinding chamber wall 3 radially outward. There, the bulk material 10 is ground by means of grinding rollers 11, which roll on the grinding table 4. The grinding rollers 11 are not usually driven by itself. However, driving the grinding rollers 11 would be possible. The crushed bulk material - to distinguish it from the unground bulk material 10 referred to as regrind 12 - is discharged in a known manner from the grinding chamber 1, for example by means of a blower, not shown.

Die bekannte Mühle arbeitet recht gut, ist jedoch relativ aufwändig konstruiert und kostenintensiv. Auch ist das Umlenkgetriebe 9 relativ störanfällig und wartungsintensiv.The well-known mill works quite well, but is relatively expensive and expensive. Also, the reversing gear 9 is relatively susceptible to interference and maintenance.

Im Stand der Technik ist weiterhin bekannt, dass der Elektromotor direkt unter dem Mahlteller angeordnet und die Wellenachse lotrecht verlaufen kann. Rein beispielhaft wird auf die DE 103 05 915 A1 , die DE 1 957 580 A1 , die US 2,192,310 A und die US 5,667,149 A verwiesen.It is furthermore known in the prior art that the electric motor can be arranged directly under the grinding table and the shaft axis can run vertically. Purely by way of example is on the DE 103 05 915 A1 , the DE 1 957 580 A1 , the US 2,192,310 A and the US 5,667,149 A directed.

Bei den bekannten Ausgestaltungen ist die Motorwelle direkt - d. h. ohne zwischengeordnetes Getriebe - mit dem Mahlteller verbunden.In the known embodiments, the motor shaft is directly - d. H. without intermediate gear - connected to the grinding table.

Die Aufgabe der vorliegenden Erfindung besteht darin, die bekannte Mühle derart zu verbessern, dass sie einfacher und kostengünstiger herstellbar ist, im Dauerbetrieb einfacher zu warten ist und eine geringere Störanfälligkeit aufweist.The object of the present invention is to improve the known mill so that they simpler and is cheaper to produce, is easier to maintain in continuous operation and has a lower susceptibility to interference.

Die Aufgabe wird bei einer Mühle der zuletzt genannten Art dadurch gelöst, dass der Elektromotor als Außenläufermotor ausgebildet ist.The object is achieved in a mill of the latter type in that the electric motor is designed as an external rotor motor.

Die Motorwelle kann mit dem Mahlteller direkt verbunden sein. Falls ein Getriebe vorhanden ist, ist die Motorwelle mit dem Mahlteller zwar über ein Getriebe verbunden, das Getriebe weist jedoch eine Getriebeeingangswelle und eine Getriebeausgangswelle auf, die zueinander parallele Rotationsachsen aufweisen. In einer bevorzugten Ausgestaltung fluchten die Rotationsachsen der Getriebeeingangswelle und der Getriebeausgangswelle (und folglich auch die Wellenachse und die Drehachse) sogar miteinander. Ein Beispiel eines Getriebes, das miteinander fluchtende Rotationsachsen aufweist, ist ein Planetengetriebe, das ein Sonnenrad, mindestens ein Planetenrad und ein Hohlrad aufweist.The motor shaft can be connected directly to the grinding table. If a transmission is present, although the motor shaft is connected to the grinding table via a transmission, the transmission has a transmission input shaft and a transmission output shaft, which have mutually parallel axes of rotation. In a preferred embodiment, the axes of rotation of the transmission input shaft and the transmission output shaft (and consequently also the shaft axis and the rotation axis) even align with each other. An example of a transmission having aligned axes of rotation is a planetary gear having a sun gear, at least one planet gear, and a ring gear.

Im Falle eines Planetengetriebes sind verschiedene Kombinationen möglich, mit welchen Rädern des Planetengetriebes die Getriebeeingangswelle und die Getriebeausgangswelle zusammenwirken. Je nach Ausgestaltung des Planetengetriebes kann die Getriebeeingangswelle mit dem Sonnenrad, dem Hohlrad oder einer Lagerung, auf der das mindestens eine Planetenrad um das Sonnenrad drehbar gelagert ist, drehfest verbunden sein. Ebenso kann die Getriebeausgangswelle mit dem Sonnenrad, dem Hohlrad oder der Lagerung des Planetenrades drehfest verbunden sein. Selbstverständlich dürfen in einer bestimmten, konkreten Ausgestaltung des Planetengetriebes die Getriebeeingangswelle und die Getriebeausgangswelle nicht mit demselben Element (Sonnenrad, Hohlrad, Lagerung des Planetenrades) verbunden sein.In the case of a planetary gear various combinations are possible with which wheels of the planetary gear, the transmission input shaft and the transmission output shaft cooperate. Depending on the configuration of the planetary gear, the transmission input shaft with the sun gear, the ring gear or a bearing on which the at least one planet gear is rotatably mounted about the sun gear, rotatably connected. Likewise, the transmission output shaft may be rotatably connected to the sun gear, the ring gear or the bearing of the planet gear. Of course, may not be connected to the same element (sun gear, ring gear, bearing of the planetary gear) in a specific, specific embodiment of the planetary gear, the transmission input shaft and the transmission output shaft.

Derzeit ist bevorzugt, dass die Motorwelle mit dem Sonnenrad verbunden ist. Der Mahlteller ist in diesem Fall entweder mit dem Hohlrad oder mit der Lagerung für das mindestens eine Planetenrad drehfest verbunden.At present it is preferred that the motor shaft is connected to the sun gear. The grinding table is in this case either with the ring gear or with the storage for the at least one planet gear rotatably connected.

Ein Rotor des Außenläufermotors ist vorzugsweise glockenförmig ausgebildet.A rotor of the external rotor motor is preferably bell-shaped.

Der Elektromotor ist vorzugsweise als langsam laufender, hochpoliger Antrieb ausgebildet. Er kann alternativ als Asynchronmotor oder als Synchronmotor ausgebildet sein. Im Falle eines Synchronmotors kann der Antrieb alternativ elektrisch oder permanent magnetisch erregt sein. Die Speisung des Elektromotors kann direkt aus dem Versorgungsnetz oder - bevorzugt - über einen Umrichter erfolgen.The electric motor is preferably designed as a slow-speed, high-pole drive. It can alternatively be designed as an asynchronous motor or as a synchronous motor. In the case of a synchronous motor, the drive may alternatively be electrically or permanently magnetically excited. The supply of the electric motor can be done directly from the supply network or - preferably - via a converter.

Die nachfolgende Beschreibung der vorliegenden Erfindung und von deren Ausgestaltungen geht aus von der obenstehend in Verbindung mit FIG 1 beschriebenen Mühle. Nachfolgend wird daher nur auf die Unterschiede der erfindungsgemäßen Ausgestaltungen näher eingegangen. Die übrigen Ausführungen zu FIG 1 bleiben weiterhin gültig.The following description of the present invention and the embodiments thereof is based on the above in connection with FIG. 1 described mill. Below, therefore, only the differences of the embodiments of the invention will be discussed in more detail. The remaining comments too FIG. 1 remain valid.

Die vorliegende Erfindung wird weiterhin in Verbindung mit einem permanent erregten Synchronmotor beschrieben, der als Außenläufermotor ausgebildet ist. Es wäre jedoch ohne weiteres möglich, anstelle des permanent erregten Synchronmotors einen elektrisch erregten Synchronmotor oder einen Asynchronmotor zu verwenden.The present invention will be further described in connection with a permanent magnet synchronous motor, which is designed as an external rotor motor. However, it would be readily possible to use an electrically excited synchronous motor or an asynchronous motor instead of the permanently excited synchronous motor.

Gemäß FIG 2 ist der Elektromotor 6 direkt unter dem Mahlteller 4 angeordnet. Er weist eine Statorwicklung 13 auf, die an einer Statorhalterung 14 befestigt ist. Die Statorwicklung 13 wirkt mit einem Rotor 15 zusammen, der im vorliegenden Fall Permanentmagnete 16 aufweist. Der Rotor 15 ist vorzugsweise glockenförmig ausgebildet. Er kann auf der Motorwelle 7 gelagert sein oder sie abschließen. Die Wellenachse 8 der Motorwelle 7 verläuft gemäß FIG 2 lotrecht.According to FIG. 2 the electric motor 6 is arranged directly under the grinding table 4. It has a stator winding 13, which is fastened to a stator holder 14. The stator winding 13 cooperates with a rotor 15, which has permanent magnets 16 in the present case. The rotor 15 is preferably bell-shaped. It can be mounted on the motor shaft 7 or complete it. The shaft axis 8 of the motor shaft 7 extends according to FIG. 2 plumb.

Die Motorwelle 7 ist bei der Ausgestaltung von FIG 2 direkt - also ohne Zwischenschalten eines Getriebes - mit dem Mahlteller 4 verbunden. Die Wellenachse 8 der Motorwelle 7 fluchtet daher mit der Drehachse 5 des Mahltellers 4.The motor shaft 7 is in the embodiment of FIG. 2 directly - ie without interposing a transmission - connected to the grinding table 4. The shaft axis 8 of the motor shaft 7 is therefore in alignment with the axis of rotation 5 of the grinding table 4.

Soweit erforderlich, kann der Mahlteller 4 radial außen und/oder zwischen seinem radial äußerem Ende und der Motorwelle 7 abgestützt sein. Im Falle einer glockenförmigen Ausgestaltung des Rotors 15 kann der Rotor 15 sogar mit dem Mahlteller 4 identisch sein.If necessary, the grinding table 4 can be supported radially outside and / or between its radially outer end and the motor shaft 7. In the case of a bell-shaped embodiment of the rotor 15, the rotor 15 may even be identical to the grinding table 4.

Die Darstellung von FIG 3 entspricht schematisch im Wesentlichen der Darstellung von FIG 2. Im Unterschied zur Ausgestaltung von FIG 2 ist bei der Ausgestaltung von FIG 3 jedoch der Mahlteller 4 mit der Motorwelle 7 über ein Getriebe 17 verbunden. Das Getriebe 17 weist eine Getriebeeingangswelle 18 und eine Getriebeausgangswelle 19 auf. Die Getriebeeingangswelle 18 und die Getriebeausgangswelle 19 weisen Rotationsachsen 20 auf, die parallel zueinander verlaufen. Die Rotationsachsen 20 können gegeneinander versetzt sein. Vorzugsweise fluchten sie jedoch miteinander.The representation of FIG. 3 corresponds schematically essentially to the representation of FIG. 2 , In contrast to the embodiment of FIG. 2 is in the embodiment of FIG. 3 However, the grinding table 4 is connected to the motor shaft 7 via a gear 17. The transmission 17 has a transmission input shaft 18 and a transmission output shaft 19. The transmission input shaft 18 and the transmission output shaft 19 have rotation axes 20 which are parallel to each other. The rotation axes 20 may be offset from each other. Preferably, however, they are aligned with each other.

Gemäß.FIG 4, die einen mögliche Spezialgestaltung der Ausgestaltung von FIG 3 zeigt, ist das Getriebe 17 als Planetengetriebe 17 ausgebildet. Es weist ein Sonnenrad 21, mindestens ein Planetenrad 22 und ein Hohlrad 23 auf. Gemäß der Ausgestaltung von FIG 4 ist die Motorwelle 7 mit dem Sonnenrad 21 drehfest verbunden.According to. FIG. 4 who have a possible special design of the design of FIG. 3 shows, the gear 17 is formed as a planetary gear 17. It has a sun gear 21, at least one planet gear 22 and a ring gear 23. According to the embodiment of FIG. 4 the motor shaft 7 is rotatably connected to the sun gear 21.

Der Mahlteller 4 ist gemäß FIG 4 mit dem Hohlrad 23 drehfest verbunden. Das mindestens eine Planetenrad 22 ist auf einer Lagerung 24 drehbar gelagert. Die Lagerung 24 ist relativ zum Sonnenrad 21 und relativ zum Hohlrad 23 drehbar.The grinding table 4 is according to FIG. 4 rotatably connected to the ring gear 23. The at least one planetary gear 22 is rotatably mounted on a bearing 24. The bearing 24 is rotatable relative to the sun gear 21 and relative to the ring gear 23.

Alternativ zu der Ausgestaltung von FIG 4 könnte der Mahlteller 4 auch mit der Lagerung 24 drehfest verbunden sein.Alternatively to the embodiment of FIG. 4 could the grinding table 4 also be rotatably connected to the storage 24.

Mittels der vorliegenden Erfindung ist es möglich, den relativ schnell laufenden Elektromotor 6 des Standes der Technik durch einen erheblich langsamer laufenden Elektromotor 6 zu ersetzen. Das wartungsintensive und störanfällige Umlenkgetriebe 9 kann entweder entfallen oder durch ein erheblich zuverlässigeres Getriebe 17 ersetzt werden, das parallel verlaufende Wellen 18, 19 aufweist. Getriebeverluste entfallen oder können reduziert werden. Der Wirkungsgrad und die Verfügbarkeit der erfindungsgemäßen Mühle sind größer als im Stand der Technik. Auch sind höhere Einheitenleistungen realisierbar.By means of the present invention, it is possible to replace the relatively fast-running electric motor 6 of the prior art by a considerably slower running electric motor 6. The maintenance-intensive and trouble-prone reversing gear 9 can either be omitted or replaced by a much more reliable transmission 17, the parallel Shafts 18, 19 has. Gear losses are eliminated or can be reduced. The efficiency and availability of the mill according to the invention are greater than in the prior art. Also, higher unit performance can be realized.
