Description

Die Erfindung betrifft eine Pendelmühle gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a pendulum mill according to the preamble of patent claim 1.

Aus der DE-PS 33 01 166 ist eine Pendelmühle bekannt, die ein Mühlengehäuse aufweist, das mit den erforderlichen Zuführeinrichtungen und Abführeinrichtungen für das Mahlgut verbunden ist. Das Mühlengehäuse umfasst ein unteres und ein oberes Mühlengehäuse, wobei das untere Mühlengehäuse an der Innenseite seiner Umfangswand eine ringförmige Mahlbahn aufweist.From the DE-PS 33 01 166 a pendulum mill is known which has a mill housing, which is connected to the required feeders and discharge means for the ground material. The mill housing comprises a lower and an upper mill housing, the lower mill housing having on the inside of its peripheral wall an annular grinding track.

Im Mühlengehäuse ist vertikal eine Antriebssäule angeordnet, an deren oberen Ende ein Querhaupt befestigt ist, an dem mehrere, die Mahlwerkzeuge bildende Mahlpendel aufgehängt sind. Die Mahlrollen der Mahlpendel werden bei rotierender Antriebssäule durch die wirkende Zentrifugalkraft gegen die Mahlbahn gedrückt.In the mill housing a drive column is arranged vertically, at the upper end of a crosshead is fixed, are suspended on the several, the grinding tools forming Mahlpendel. The grinding rollers of the Mahlpendel be pressed with rotating drive column by the acting centrifugal force against the grinding path.

Am unteren Ende der Antriebssäule ist ein Getriebe und seitlich des Getriebes ein Antriebsmotor angeordnet. Sowohl das untere Mühlengehäuse als auch der Antriebsmotor sind auf dem Gebäudeboden befestigt.At the lower end of the drive column, a transmission and the side of the transmission, a drive motor is arranged. Both the lower mill housing and the drive motor are mounted on the building floor.

Im Betrieb der Pendelmühle werden sowohl von dem Antriebsmotor und der Getriebeeinheit als auch von den Mahlwerkzeugen in verschiedenen Bereichen der Pendelmühle Schwingungen erzeugt, die nicht nur einen entsprechend hohen Geräuschpegel verursachen, sondern vor allem zu einer erheblichen Belastung des Materials der Pendelmühle und somit zu einem erhöhten Verschleiß der Bauteile der Pendelmühle führen.In the operation of the pendulum mill oscillations are generated by both the drive motor and the gear unit and the grinding tools in different areas of the pendulum mill, which not only cause a correspondingly high noise level, but especially to a considerable load on the material of the pendulum mill and thus to an increased Wear of the components of the pendulum mill lead.

Auf dem Mühlengehäuse ist gemäß der DE-PS 33 01 166 ein Sichtergehäuse mit einem Klappenwindsichter angeordnet. Derartige Pendelmühlen sind seit vielen Jahren im Einsatz und arbeiten zuverlässig.On the mill housing is in accordance with the DE-PS 33 01 166 a classifier housing arranged with a Klappenwindsichter. Such pendulum mills have been in use for many years and work reliably.

Die Mahlwerkzeuge und der Antriebsmotor sowie Kupplung und Getriebe müssen allerdings gewartet und gegebenenfalls nach Auftreten von Verschleiß auch repariert werden, was teilweise zu langen Ausfallzeiten führt, weil die Zugänglichkeit zu den betreffenden Bauteilen der Pendelmühle bei der bisherigen Bauweise nur nach aufwendigen Aus- und Umbauten möglich ist.However, the grinding tools and the drive motor and clutch and gearbox have to be maintained and possibly repaired after the occurrence of wear, which sometimes leads to long downtime, because the accessibility to the relevant components of the pendulum mill in the previous design only after elaborate extensions and conversions possible is.

Die FR 1 414 924 A offenbart eine Pendelmühle mit einem Mühlengehäuse, in dem eine Antriebswelle angeordnet ist, an deren oberen Ende Mahlpendel aufgehängt sind, und mit einer mit dem unteren Ende der Antriebswelle verbundenen Antriebseinrichtung. Der Motor selbst, der mittels eines Zahnriemens mit einer Zahnriemenscheibe verbunden ist, ist nicht dargestellt. Es ist davon auszugehen, dass dieser auf einem entsprechenden Fundament angeordnet ist.The FR 1 414 924 A discloses a pendulum mill with a mill housing, in which a drive shaft is arranged, are suspended at the upper end Mahlpendel, and with a connected to the lower end of the drive shaft drive means. The engine itself, which is connected by means of a toothed belt with a toothed belt pulley is not shown. It can be assumed that this is arranged on a corresponding foundation.

Es ist Aufgabe der Erfindung, eine Pendelmühle anzugeben, bei der sowohl die Geräuschentwicklung als auch die Materialbelastung durch Schwingungen reduziert wird.It is an object of the invention to provide a pendulum mill, in which both the noise and the material load is reduced by vibrations.

Diese Aufgabe wird mit einer Pendelmühle gelöst, bei der die Antriebseinrichtung an der Bodenwand des Mühlengehäuses freihängend angeordnet ist.This object is achieved with a pendulum mill, in which the drive device is arranged freely suspended on the bottom wall of the mill housing.

Die Antriebseinrichtung ist vorzugsweise an der Unterseite der Bodenwand angeordnet.The drive device is preferably arranged on the underside of the bottom wall.

Es hat sich gezeigt, dass bei einer Befestigung der Antriebseinrichtung auf dem Gebäudeboden, auf dem auch das Mühlengehäuse angeordnet ist, der Antriebsstrang ein eigenes Schwingungssystem bildet, das sich in der Regel asynchron zum Schwingungssystem des Mühlengehäuses und der darin befindlichen umlaufenden Mahlwerkzeuge verhält, was insgesamt zu einer erhöhten Materialbelastung der Bauteile der Pendelmühle führt. Insbesondere dann, wenn die beiden Schwingungssysteme gegenläufige Schwingungen erzeugen, führt dies zu einem erhöhten Verschleiß der Bauteile.It has been found that with a fastening of the drive device on the building floor, on which the mill housing is arranged, the drive train forms its own vibration system, which usually behaves asynchronous to the vibration system of the mill housing and the circulating grinding tools therein, which in total leads to an increased material load of the components of the pendulum mill. In particular, when the two vibration systems generate opposing vibrations, this leads to increased wear of the components.

Die freihängende Anordnung der Antriebseinrichtung an der Bodenwand des Mühlengehäuses hat demgegenüber den Vorteil, dass die Antriebseinrichtung keine Verbindung zum Gebäudeboden bzw. dem Fundament hat, auf dem das Mühlengehäuse steht. Durch diese Entkopplung wird erreicht, dass die Antriebseinrichtung und das Mühlengehäuse ein gemeinsames Schwingungssystem bilden, das dementsprechend gemeinsame Schwingungen erzeugt, die weitaus materialschonender sind.The freely suspended arrangement of the drive device on the bottom wall of the mill housing has the advantage that the drive device has no connection to the building floor or the foundation on which the mill housing is. Through this decoupling is achieved that the drive device and the mill housing form a common vibration system, which accordingly generates common vibrations, which are far more gentle on materials.

Asynchrone oder gegenläufige Schwingungen können erst gar nicht auftreten, so dass das Material der Komponenten der Pendelmühle geschont und gleichzeitig die Geräuschentwicklung reduziert wird.Asynchronous or opposite vibrations can not occur at all, so that the material of the components of the pendulum mill is protected and at the same time the noise is reduced.

Die Pendelmühle ist vorzugsweise eine getriebelose Pendelmühle. Der Verzicht auf ein Getriebe spart Platz, wodurch insbesondere die Bauhöhe verringert werden kann. Wenn - wie es in der Regel der Fall ist - das Getriebe unter dem Mühlengehäuse auf dem Fundament angeordnet ist, kann bei einem Verzicht auf ein Getriebe dort auch die Baubreite reduziert werden.The pendulum mill is preferably a gearless pendulum mill. The absence of a gearbox saves space, which in particular the height can be reduced. If - as is usually the case - the gear is located under the mill housing on the foundation, there can be reduced in a waiver of a gearbox there and the width.

Vorzugsweise ist die Antriebseinrichtung ein Direktantrieb. Ein solcher Direktantrieb ist durch eine stufenlose Drehzahlregelung gekennzeichnet und weist weder eine Kupplung noch ein Getriebe auf. Der Vorteil eines Direktantriebs besteht somit darin, dass er sowohl kompakt ist als auch im Wesentlichen rotationssymmetrisch zu der Ausgangswelle ausgebildet ist. Im Betrieb ist der Direktantrieb schwingungsarm und trägt deshalb neben der Schwingungsentkopplung durch die freihängende Anordnung zusätzlich zu einer Verringerung der Materialbeanspruchung der Bauteile der Pendelmühle bei.Preferably, the drive device is a direct drive. Such a direct drive is characterized by a stepless speed control and has neither a clutch nor a transmission. The advantage of a direct drive is thus that it is both compact and is formed substantially rotationally symmetrical to the output shaft. In operation, the direct drive is low in vibration and therefore contributes in addition to the vibration isolation by the free-hanging arrangement in addition to a reduction in the material stress of the components of the pendulum mill.

Weitere Vorteile eines Direktantriebs bestehen darin, dass er wartungsfreundlich ist, weil z. B. kein Getriebeöl benötigt wird, das von Zeit zu Zeit erneuert werden muss. Ferner sind kein Getriebe und keine Motorkupplung vorhanden, die instandgehalten werden müssen. Der Energieverbrauch eines Direktantriebs ist deutlich niedriger, als dies bei herkömmlichen Antriebseinrichtungen, wie sie beispielsweise auch in der DE-PS 33 01 166 vorgesehen sind, der Fall ist.Other advantages of a direct drive are that it is easy to maintain because z. B. no gear oil is needed, which must be renewed from time to time. Furthermore, there is no transmission and no engine clutch maintained Need to become. The energy consumption of a direct drive is significantly lower than that of conventional drive devices, such as those in the DE-PS 33 01 166 are provided, this is the case.

Bevorzugte Direktantriebe sind beispielsweise ein Hydraulikmotor oder ein Torquemotor.Preferred direct drives are, for example, a hydraulic motor or a torque motor.

Bei Hydraulikmotoren, die auch als Hydromotoren bezeichnet werden, wird hydraulische Energie in mechanische Arbeit umgewandelt. Es existieren eine Vielzahl von Bauarten von Hydraulikmotoren, die in ihrer Arbeitsweise im Wesentlichen in Konstant- und Verstellmotoren eingeteilt werden können. Für den Einsatz in einer Pendelmühle sind Verstellmotoren bevorzugt, um die Umlaufgeschwindigkeit der Mahlwerkzeuge einstellen zu können. Das von hydrodynamischen Motoren erzeugte Drehmoment ist unabhängig von der Drehzahl steuerbar. Das maximale Drehmoment eines Hydraulikmotors wird durch den Druck der Hydraulikflüssigkeit bestimmt. Das so genannte Schluckvolumen bestimmt die Drehzahl, die vom zugeführten Volumenstrom abhängig ist.Hydraulic motors, also referred to as hydraulic motors, convert hydraulic energy into mechanical work. There are a variety of types of hydraulic motors that can be classified in their operation essentially in constant and variable motors. For use in a pendulum mill adjusting motors are preferred in order to adjust the rotational speed of the grinding tools can. The torque generated by hydrodynamic motors can be controlled independently of the speed. The maximum torque of a hydraulic motor is determined by the pressure of the hydraulic fluid. The so-called displacement determines the speed, which depends on the supplied volume flow.

Besonders bevorzugt sind Torquemotoren, weil diese elektrisch betrieben werden und im Vergleich zu Hydraulikmotoren keine Zu- und Ableitungen für die Hydraulikflüssigkeit benötigen. Torquemotoren erfordern lediglich einen Kühlwasserkreislauf. Ein Torquemotor ist ein vielpoliger Elektromotor mit sehr hohen Drehmomenten und relativ kleinen Drehzahlen.Torque motors are particularly preferred because they are operated electrically and, in comparison to hydraulic motors, do not require any supply and discharge lines for the hydraulic fluid. Torque motors only require a cooling water circuit. A torque motor is a multi-pole electric motor with very high torques and relatively low speeds.

Vorzugsweise ist der Torquemotor vertikal eingebaut, so dass die Ausgangswelle des Torquemotors vertikal ausgerichtet ist.Preferably, the torque motor is installed vertically, so that the output shaft of the torque motor is vertically aligned.

Vorzugsweise weist der Direktantrieb eine Ausgangswelle auf, die mit der Antriebswelle verbunden ist.Preferably, the direct drive has an output shaft which is connected to the drive shaft.

Es ist besonders bevorzugt, dass der Direktantrieb eine Ausgangswelle aufweist, die mit der Antriebswelle der Pendelmühle identisch ist. Diese Ausführungsform hat den Vorteil, dass sie noch kompakter ist und bezüglich der Montage keine zusätzlichen Verbindungen zwischen Ausgangswelle und Antriebswelle erforderlich macht.It is particularly preferred that the direct drive has an output shaft that is identical to the drive shaft of the pendulum mill. This embodiment has the advantage that it is even more compact and makes no additional connections between the output shaft and drive shaft with respect to the assembly required.

Vorzugweise ist die Antriebswelle, insbesondere bei der einteiligen Ausgestaltung der Welle, ausschließlich im Direktantrieb gelagert. Diese Ausführungsform hat den Vorteil, dass bei der Montage des Direktantriebs und der Antriebswelle keine Lagerstellen z. B. am Mühlengehäuse vorgesehen werden müssen, was die gesamte Anordnung der Komponenten der Pendelmühle weiter vereinfacht.Preferably, the drive shaft, especially in the one-piece design of the shaft, mounted exclusively in the direct drive. This embodiment has the advantage that when mounting the direct drive and the drive shaft no bearings z. B. must be provided on the mill housing, which further simplifies the entire arrangement of the components of the pendulum mill.

Es ist weiterhin bevorzugt, die Antriebseinrichtung an einer Montageplatte, insbesondere lösbar, zu befestigen. Die Befestigung an der Montageplatte kann unmittelbar oder mittelbar vorgesehen sein.It is further preferred to attach the drive device to a mounting plate, in particular releasably. The attachment to the mounting plate may be provided directly or indirectly.

Vorteilhafterweise ist die Montageplatte mit der Bodenwand des Mühlengehäuses lösbar verbunden. Die Antriebseinrichtung mit Welle und gegebenenfalls mit den Mahlwerkzeugen kann zusammen mit der Montageplatte vorgefertigt werden und kann als fertige Baueinheit auf einfache Weise, vorzugsweise von oben, in das Gehäuse der Pendelmühle eingesetzt werden.Advantageously, the mounting plate is detachably connected to the bottom wall of the mill housing. The drive means with shaft and optionally with the grinding tools can be prefabricated together with the mounting plate and can be used as a finished unit in a simple manner, preferably from above, in the housing of the pendulum mill.

Vorzugsweise ist die Montageplatte ein Teil der Bodenwand des Mühlengehäuses. Hierzu weist die Bodenwand des Mühlengehäuses vorzugweise einen Ausschnitt auf, in den die Montageplatte eingesetzt werden kann.Preferably, the mounting plate is a part of the bottom wall of the mill housing. For this purpose, the bottom wall of the mill housing preferably a cutout into which the mounting plate can be used.

Die Montageplatte ist vorzugsweise nach oben entnehmbar. Die Bodenwand weist zu diesem Zweck vorzugsweise an ihrer Innenseite am Rand des Ausschnitts eine Auflagefläche für die Montageplatte, beispielsweise eine Ausnehmung zur Aufnahme der Montageplatte oder einen Ringflansch auf. Die Abnahme der Montageplatte nach oben hat den Vorteil, dass die Antriebseinrichtung mit dazugehöriger Welle nach oben herausgehoben werden kann. Ein Zerlegen von Antriebseinrichtung und Welle unterhalb der Bodenwand des Mühlengehäuses ist nicht erforderlich, so dass kein entsprechend großer Bauraum vorgesehen sein muss. Die Pendelmühle ist dadurch kompakt ausgeführt.The mounting plate is preferably removed upwards. The bottom wall has for this purpose preferably on its inside at the edge of the cutout a bearing surface for the mounting plate, for example a recess for receiving the mounting plate or an annular flange. The removal of the mounting plate Upwards has the advantage that the drive device with associated shaft can be lifted upwards. A disassembly of drive means and shaft below the bottom wall of the mill housing is not required, so that no correspondingly large space must be provided. The pendulum mill is thus made compact.

Die Bodenwand des Mühlengehäuses weist vorzugsweise mindestens eine Verriegelungseinrichtung auf, die in Verriegelungsstellung die Montageplatte festlegt. Die Montageplatte weist hierzu entsprechende Mittel auf, die mit der Verriegelungseinrichtung der Bodenwand zusammenwirken.The bottom wall of the mill housing preferably has at least one locking device which defines the mounting plate in the locking position. For this purpose, the mounting plate has corresponding means which cooperate with the locking device of the bottom wall.

Die Verriegelungseinrichtung weist vorzugsweise mindestens einen sich vorzugsweise in horizontaler Richtung verschiebbaren Verriegelungsbolzen auf.The locking device preferably has at least one preferably in the horizontal direction displaceable locking bolt.

Ferner kann die Verriegelungseinrichtung eine Betätigungseinrichtung aufweisen, was die Möglichkeit eröffnet, den Ein- und Ausbau der Antriebseinrichtung mit Antriebswelle und Mahlwerkzeugen als Baueinheit zu ermöglichen oder zu erleichtern.Furthermore, the locking device may comprise an actuating device, which opens up the possibility to enable or facilitate the installation and removal of the drive device with drive shaft and grinding tools as a structural unit.

Vorzugsweise ist ein Schaufelteller oberhalb der Montageplatte mit der Antriebswelle drehfest verbunden. Auch der Schaufelteller kann vor dem Einbau der Antriebseinrichtung vormontiert werden. Die austauschbare Baueinheit umfasst bei dieser Ausführungsform die Antriebseinrichtung, die Montageplatte, die Antriebswelle mit den Mahlwerkzeugen und dem Schaufelteller.Preferably, a blade plate is rotatably connected above the mounting plate with the drive shaft. Also, the blade plate can be pre-assembled before installing the drive device. The replaceable assembly comprises in this embodiment, the drive means, the mounting plate, the drive shaft with the grinding tools and the blade plate.

Vorzugsweise ist das Mühlengehäuse auf einem Schwingfundament angeordnet. Es wird dadurch eine weitere Schwingungsdämpfung bewirkt, wobei die Antriebseinrichtung keine unmittelbare Verbindung mit diesem Schwingfundament aufweist.Preferably, the mill housing is arranged on a vibrating foundation. It is thereby effected a further vibration damping, wherein the drive means has no direct connection with this vibrating foundation.

Es ist zur Verringerung der Bauhöhe der Pendelmühle bevorzugt, wenn das Schwingfundament eine Aufnahmekammer aufweist, in die die Antriebseinrichtung freihängend hineinragt.It is preferred for reducing the overall height of the pendulum mill when the oscillating foundation has a receiving chamber into which the drive device protrudes freely suspended.
