Description

Beschreibung: Description:
Wälzmühleroller mill
Technisches Gebiet:Technical area:
Die Erfindung betrifft Wälzmühlen, umfassend ein Gehäuse, einen Mahlteller mit Antrieb, auf dem Mahlteller abrollende Mahlwalzen, Schwingen und Schwingenachsen für jede Mahlwalze, und Spannvorrichtungen mit Hydraulikzylinder zum Anpressen der Mahlwalzen an den Mahlteller.The invention relates to roller mills, comprising a housing, a grinding table with drive, grinding rollers rolling on the grinding table, rockers and rocker axes for each grinding roller, and clamping devices with hydraulic cylinders for pressing the grinding rollers to the grinding table.
Stand der Technik:State of the art:
Wälzmühlen unterliegen einem mehr oder weniger großen Verschleiß. Insbesondere betroffen sind die Mahlwalzen und die Mahlbahn. Müssen diese Teile gewartet oder repariert werden, so müssen die Mahlwalzen in der Regel aus dem Mahlraum herausgenommen werden. Hierzu verwenden die Mühlenhersteller und -betreiber spezielle, an den jeweiligen Mühlentyp angepasste Handhabungsvorrichtungen. Das können sein schlittenartige Vorrichtungen, ins Mühleninnere geführte Kranbahnen oder auch hydraulische HilfsVorrichtungen. Zum Teil müssen die Mahlwalzen komplett von ihrer Walzenführung gelöst werden, um den Ausbau zu ermöglichen. Bei anderen Konstruktionen müssen Walzenführung und Spannzylinder getrennt werden, um mit Hilfszylindern die Walzen aus dem Gehäuse herausschwenken zu können. Man vergleiche beispielsweise DE 10 2004 062 400 A.Roller mills are subject to more or less wear. Particularly affected are the grinding rollers and the grinding track. If these parts have to be serviced or repaired, the grinding rollers usually have to be removed from the grinding chamber. The mill manufacturers and operators use special handling devices adapted to the respective mill type. This can be sled-like devices, run into the mill interior crane tracks or hydraulic auxiliary devices. In part, the grinding rollers must be completely detached from their roller guide to allow the removal. In other constructions roll guide and clamping cylinder must be separated in order to pivot out of the housing with auxiliary cylinders, the rollers. For example, compare DE 10 2004 062 400 A.
Weil die Mahlwalzen und ihre Lager- und Spannvorrichtungen mehrere zehn Tonnen schwer sein können, sind die benötigten HilfsVorrichtungen entsprechend groß zu dimensionieren. Die Handhabung dieser HilfsVorrichtungen und die Manipulation der Mahlwalzen ist aufgrund der großen Gewichte zeitaufwändig und mühsam. Das ist unbefriedigend.Because the grinding rollers and their storage and tensioning devices can be several tens of tons heavy, the required auxiliary devices are to be dimensioned correspondingly large. The handling of these auxiliary devices and the manipulation of the grinding rollers is time-consuming and cumbersome due to the large weights. That is unsatisfactory.
Kurze Beschreibung der Erfindung:Brief description of the invention:
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Wälzmühle anzugeben, bei der die Mahlwalzen einfach und schnell aus dem Mühlengehäuse herausgeschwenkt werden können. Diese Aufgabe wird gelöst durch eine Wälzmühle mit den Merkmalen: für jede Mahlwalze ist eine Ausschwenkvorrichtung mit einer Ausschwenkachse vorgesehen, die Hydraulikzylinder der Spannvorrichtungen sind in der Lage, die Mahlwalzen aus dem Gehäuse herauszuschwenken.The present invention has for its object to provide a roller mill, in which the grinding rollers can be easily and quickly swung out of the mill housing. This object is achieved by a roller mill having the features: for each grinding roller a swivel device is provided with a swivel-out, the hydraulic cylinders of the clamping devices are able to herauszuschwenken the grinding rollers out of the housing.
Dank der Verwendung von Hydraulikzylindern, die die Mahlwalzen nicht nur spannen und von der Mahlbahn abheben sondern die Mahlwalzen insgesamt aus dem Gehäuse herausschwenken können, entfallen jegliche an- und abzubauende HilfsVorrichtungen. Es ist lediglich erforderlich, eine Ausschwenkachse vorzusehen, wobei gemäß einer besonderen Ausgestaltung der Erfindung die während des Mahlbetriebs aktive Schwingenachse auch die Funktion der Ausschwenkachse übernehmen kann.Thanks to the use of hydraulic cylinders, which not only tension the grinding rollers and lift them off the grinding track, but also allow the grinding rollers to swing out of the housing altogether, there is no need for any auxiliary devices to be mounted and dismounted. It is only necessary to provide a swivel-out, wherein according to a particular embodiment of the invention, the active during the grinding operation swing axle can also take over the function of the swivel-out.
Vorteilhafterweise sind die Mahlwalzen auf Konsolen gelagert, die neben dem Mühlengehäuse stehen. Dank dieser Konstruktion wird das Mühlengehäuse nicht durch die Mahlkräfte belastet.Advantageously, the grinding rollers are mounted on brackets, which stand next to the mill housing. Thanks to this construction, the mill housing is not burdened by the grinding forces.
Um die Bewegungsmöglichkeiten der Mahlwalzen zu verbessern, insbesondere im Hinblick auf das Ausschwenken derselben aus dem Gehäuse, sind die Hydraulikzylinder vorzugsweise neben den Konsolen positioniert und nicht wie beim oben genannten Stand der Technik zwischen Konsole und Mühlengehäuse.In order to improve the possibilities of movement of the grinding rollers, in particular with regard to the pivoting thereof out of the housing, the hydraulic cylinders are preferably positioned next to the brackets and not between console and mill housing as in the above-mentioned prior art.
Sind Schwingenachse und Ausschwenkachse getrennt, so sind sie gemäß einer Ausgestaltung der Erfindung senkrecht zueinander orientiert. Dies vereinfacht die konstruktive Umsetzung des Ausschwenkens.If the pivot axis and the pivot axis are separated, they are oriented perpendicular to one another according to an embodiment of the invention. This simplifies the structural implementation of the swiveling out.
Gemäß einer bevorzugten Ausgestaltung der Erfindung sind lösbare Verbindungen vorgesehen, die wechselseitig eine der Achsen blockieren. Dadurch ist sichergestellt, dass die Mahlwalzen jeweils die gewünschte Bewegung ausführen.According to a preferred embodiment of the invention detachable connections are provided which mutually block one of the axes. This ensures that the grinding rollers each perform the desired movement.
Gemäß einer Weiterbildung hierzu ist zur Blockierung der Schwingenachse und/oder zur Begrenzung des Hubs der Mahlwalzen eine lösbare Verbindungsstange vorgesehen. Durch geeignete Geometrie dieser Verbindungsstange lässt sich die Schwingenachse in jeder gewünschten Position blockieren. Dies ist insbesondere dann von Vorteil, wenn die Mahlwalzen im Teillastbetrieb der Mühle von der Mahlbahn abgehoben werden, oder aus dem Mühlengehäuse herausgeschwenkt werden. Gemäß einer weiteren Ausgestaltung der Erfindung sind zur Blockierung der Ausschwenkachse Schrauben vorgesehen. Eine solche Schraubverbindung ist ohne Nachteil einzusetzen, da die Mahlwalzen nur in seltenen Fällen ganz ausgeschwenkt werden.According to a further development, a releasable connecting rod is provided for blocking the rocker axis and / or for limiting the stroke of the grinding rollers. By suitable geometry of this connecting rod, the swingarm axis can be blocked in any desired position. This is particularly advantageous when the grinding rollers are lifted in part-load operation of the mill of the grinding path, or be swung out of the mill housing. According to a further embodiment of the invention, screws are provided for blocking the Ausschwenkachse. Such a screw is used without any disadvantage, since the grinding rollers are only completely swung out in rare cases.

Wege zur Ausführung der Erfindung und gewerbliche Verwertbarkeit:Ways to carry out the invention and commercial usability:
Die Fig. 1 bis 3 zeigen eine erste Wälzmühle mit einem Mühlengehäuse 9, in dem eine Mahlbahn 2 rotierend angeordnet ist. Angetrieben wird die Mahlbahn 2 durch einen Antrieb 10. Vier Mahlwalzen 3 sind an Schwingen 6 gelagert, die eine Schwingenachse 7 besitzen. An den Schwingen 6 greifen Hydraulikzylinder 1 an, mit deren Hilfe die Mahlwalzen 3 mit definierter Kraft gegen die Mahlbahn 2 und das während des Mahlbetriebs darauf liegende Mahlgut gepresst werden. Dabei oszillieren die Mahlwalzen 3 um die Schwingenachsen 7.1 to 3 show a first roller mill with a mill housing 9, in which a grinding track 2 is arranged to rotate. The grinding track 2 is driven by a drive 10. Four grinding rollers 3 are mounted on rockers 6, which have a rocker axis 7. At the wings 6 hydraulic cylinders 1 attack, with the aid of the grinding rollers 3 are pressed with defined force against the grinding path 2 and the grinding material lying thereon during the grinding operation. The grinding rollers 3 oscillate about the rocker axes 7.
Wie die Fig. 1 bis 3 zeigen, sind die Mahlwalzen 3 und die Schwingen 6 auf Konsolen 8 positioniert, die neben dem Mühlengehäuse 9 stehen.As shown in FIGS. 1 to 3, the grinding rollers 3 and the wings 6 are positioned on brackets 8, which are adjacent to the mill housing 9.
Die Fig. 2 und 3 zeigen das Ausschwenken der Mahlwalzen 3 aus dem Gehäuse 9, beispielsweise zu Wartungszwecken. Zu diesem Zweck sind zwischen den Konsolen 8 und den Schwingen 6 Ausschwenkachsen 4 vorgesehen, die jeweils senkrecht zu den Schwingenachsen 7 orientiert sind. Des weiteren sind die Hydraulikzylinder 1 neben den Konsolen 8 positioniert. Dank dieser Maßnahmen können durch Ausfahren der Hydraulikzylinder 1 die Mahlwalzen 3 mit ihren Schwingen 6 um ihre Ausschwenkachse 4 aus dem Mühlengehäuse 9 herausgeschwenkt werden. Der Hydraulikzylinder 1 bleibt im Eingriff. Es wird lediglich die Schwingenachse 7 blockiert und die Ausschwenkachse 4 freigegeben. Das bedeutet eine erhebliche Arbeits- und Zeitersparnis. Das vereinfachte, weil geführte Handling der mehrere zehn Tonnen schweren Bauteile dient nicht zuletzt auch der Arbeitssicherheit.Figs. 2 and 3 show the pivoting of the grinding rollers 3 from the housing 9, for example, for maintenance purposes. For this purpose are between the consoles. 8 and the rockers 6 Ausschwenkachsen 4 are provided, which are each oriented perpendicular to the rocker axes 7. Furthermore, the hydraulic cylinders 1 are positioned next to the brackets 8. Thanks to these measures, the grinding rollers 3 can be swung out with their wings 6 by their Auswenkachse 4 from the mill housing 9 by extending the hydraulic cylinder 1. The hydraulic cylinder 1 remains engaged. It is only the swing axle 7 blocked and the Ausschwenkachse 4 released. This means a considerable work and time savings. The simplified, guided handling of components weighing several tens of tons also serves to ensure occupational safety.
Fig. 4 zeigt in vergrößertem Maßstab einen Ausschnitt aus der Wälzmühle der Fig. 1 bis 3 im Bereich einer Schwinge 6. Der Hydraulikzylinder 1 steht neben der Konsole 8 und ist mit der Schwinge 6 unterhalb der Welle der Mahlwalze 3 beweglich verbunden. Zwischen der Schwinge 6 und der Schwingenlagerung ist eine Verbindungsstange 5 verlegt. Diese blockiert die Schwingenachse 7 und stellt je nach Länge die Position der Mahlwalze 3 über der Mahlbahn ein.1 to 3 in the region of a rocker 6. The hydraulic cylinder 1 is adjacent to the bracket 8 and is movably connected to the rocker 6 below the shaft of the grinding roller 3. Between the rocker 6 and the swingarm bearing a connecting rod 5 is laid. This blocks the rocker axis 7 and sets the position of the grinding roller 3 over the grinding path, depending on the length.
Des weiteren zeigt die Fig. 4, dass auch die Ausschwenkachse 4 blockiert werden kann. Hierzu sind Schraubenverbindungen 51 vorgesehen.Furthermore, Fig. 4 shows that the Ausschwenkachse 4 can be blocked. For this purpose, screw 5 1 are provided.
Fig. 5 schließlich zeigt einen Schnitt durch eine zweite Wälzmühle, bei der die Ausschwenkachse 4 und die Schwingenachse 7 identisch sind. Dies vereinfacht die Konstruktion nochmals zusätzlich. Das Spannen der Mahlwalzen 3 einerseits und das Abheben der Mahlwalzen 3 von der Mahlbahn 2 zum Zweck des Anfahrens der Mühle andererseits und das Ausschwenken der Mahlwalzen 3 aus dem Mühlengehäuse 9 erfolgen durch geeignete Steuerung der Hydraulikzylinder 1. Finally, FIG. 5 shows a section through a second roller mill, in which the swivel-out axis 4 and the rocker axis 7 are identical. This simplifies the construction again in addition. The clamping of the grinding rollers 3 on the one hand and the lifting of the grinding rollers 3 from the grinding track 2 for the purpose of starting the mill on the other hand and the pivoting of the grinding rollers 3 from the mill housing 9 by suitable control of the hydraulic cylinder. 1
