Description

Rollenpresse mit verbreitertem Rahmenkopf  Roller press with widened frame head
Die Erfindung betrifft eine Rollenpresse zur Zerkleinerung von sprödem Mahlgut, aufweisend mindestens zwei Mahlwalzen, einen Maschinenrahmen, der mindestens einen Obergurt und/oder mindestens ein zusammenhängendes oberes Rahmenelement aufweist, und mindestens einen Untergurt und/oder mindestens ein zusammenhängendes unteres Rahmenelement aufweist, mindestens einen Rahmenkopf zur Stabilisierung des mindestens einen Obergurts oder des mindestens ein zusammenhängenden, oberen Rahmenelements, wenn die Rollenpresse zum Wechsel der Mahlwalzen kopfseitig geöffnet ist, wobei der Rahmenkopf aus einer oberen Quertraverse besteht, die durch mindestens zwei seitliche Stützen abgestützt ist und mit dem mindestens einen Obergurt oder dem mindestens einen zusammenhängenden, oberen Rahmenelement verbunden ist. The invention relates to a roller press for crushing brittle grinding material, comprising at least two grinding rollers, a machine frame having at least one upper flange and / or at least one coherent upper frame member, and at least one lower flange and / or at least one coherent lower frame member having at least one frame head for stabilizing the at least one upper belt or the at least one continuous, upper frame element, when the roller press for changing the grinding rollers is open at the head, wherein the frame head consists of an upper cross-beam, which is supported by at least two lateral supports and with the at least one upper flange or the at least one continuous, upper frame member is connected.
Zur Hochdruckzerkleinerung von Schüttgut ist es bekannt, das Schüttgut durch den Walzenspalt zweier gegenläufig rotierender Walzen passieren zu lassen, wo das Schüttgut durch Anwendung von hohem Druck berstet und zu Schülpen ge- presst wird. Bei dieser Art der Zerkleinerung wird das zu zerkleinernde Material nicht mit einer scherenden Bewegung zerkleinert, sondern im Idealfall ausschließlich durch die Anwendung von hohem Druck auf das Schüttgut im Walzenspalt, wo das spröde Schüttgut ausschließlich durch die Druckanwendung in ein feines Korn bricht. For high-pressure crushing of bulk material, it is known to let the bulk material pass through the nip of two counter-rotating rollers, where the bulk material is burst by the application of high pressure and pressed into slugs. In this type of crushing the material to be crushed is not crushed with a shearing motion, but ideally only by the application of high pressure on the bulk material in the nip, where the brittle bulk breaks only by the application of pressure into a fine grain.
Auch wenn bei der ausschließlich auf Druck optimierten Zerkleinerung der Verschleiß der Mahlwalzen vergleichsweise gering ist gegenüber Mühlenanordnungen, in denen auch eine Scherbeanspruchung das Mahlgut zerkleinert, so ist es bei einem hohen Durchsatz dieser Rollenpressen notwendig, die Mahlwalzen regelmäßig zu erneuern oder aufzuarbeiten. Even if the wear of the grinding rolls, which is optimized exclusively for pressure, is comparatively low compared to mill arrangements in which a shear stress also comminutes the ground material, this is the case With a high throughput of these roller presses necessary to renew the grinding rollers regularly or work up.
Um die Standzeit während des Rollenwechsels möglichst gering zu halten, ist man daran interessiert, die Rollenpresse leicht demontieren zu können, um die verschlissenen Mahlwalzen aus der Rollenpresse zu entfernen und andere, neue oder aufgearbeitete Rollenpressen wieder einarbeiten zu können. Zur Demontage ist es üblich, an einem Kopfende eines Maschinenrahmens die Kopfelemente zu entfernen und die Mahlwalzen mitsamt ihren gleitend auf Gleitschienen gelagerten Lagerböcken nach vorn aus der Rollenpresse herauszuziehen. Bei der Demontage verbleibt so ein geöffneter Maschinenrahmen mit einem typischen, kopfseitigen Öffnungsmaul. Damit der Maschinenrahmen im geöffneten Zustand nicht unter seinem eigenen Gewicht verformt, ist es notwendig, den Maschinenrahmen entsprechend stabil auszugestalten oder Obergurte des Maschinenrahmens zu entfernen. Die Entfernung der Obergurte bedarf jedoch eines erheblichen Arbeits- und Zeitaufwands, der die Standzeit der Rollenpresse unerwünscht verlängert. Eine weitere Entwicklung in der Rollenpressentechnik führt zu stets leichteren Maschinenrahmen, damit diese auch an entfernt gelegene Orte transportiert werden können, wie beispielsweise in Wüstengebiete oder schwer zugängliche Minen. Die stets leichter werdenden Maschinenrahmen sind dazu in der Lage, die Kräfte im Maschinenrahmen bei der Hochdruckzerkleinerung aufnehmen, jedoch werden die Maschinenrahmen vergleichsweise instabil, wenn diese das eingangs beschrieben offene Öffnungsmaul aufweisen. In order to keep the service life during the reel change as low as possible, it is interested to be able to dismantle the roller press easily to remove the worn grinding rollers from the roller press and to be able to incorporate other new or reconditioned roller presses again. For disassembly, it is customary to remove at a head end of a machine frame, the head elements and pull the grinding rollers together with their bearing slidably mounted on slide rails out of the roller press. When disassembling so remains an open machine frame with a typical, head-side opening mouth. So that the machine frame does not deform under its own weight in the opened state, it is necessary to design the machine frame accordingly stably or to remove upper belts of the machine frame. However, the removal of the upper chords requires considerable labor and time, which undesirably prolongs the life of the roller press. Another development in roller press technology is leading to ever lighter machine frames, so that they can be transported to remote locations, such as desert areas or hard to reach mines. The always lighter machine frame are able to absorb the forces in the machine frame in the high pressure crushing, but the machine frame are relatively unstable if they have the open mouth described above.
In der deutschen Offenlegungsschrift DE 10 2005 045 273 A1 wird ein Maschinenrahmen für eine Hochdruckwalzenpresse offenbart, welche kopfseitig eine über seitliche Stützen abgestützte Quertraverse aufweist, welche den Obergurt oder das obere Rahmenelement im geöffneten Zustand des Maschinenrahmens abstützt. Dabei bildet die kopfseitige Quertraverse mit ihren Stützen ein integriertes Element des Maschinenrahmens, in das ein Kopfelement des Maschinenrahmens integriert ist, wobei das Kopfelement als Widerlager für die hohen Kräfte der Mahlwalzen bei der Hochdruckzerkleinerung dient. Um den Maschinenrah- men zu öffnen, ist vorgesehen, dass das Kopfelement am Obergurt des Maschinenrahmens pendelnd aufgehängt ist, und zur Öffnung wird das Kopfelement zur Seite und nach oben geschwenkt. German published patent application DE 10 2005 045 273 A1 discloses a machine frame for a high-pressure roll press, which has a cross-head supported by lateral supports on the head side, which supports the upper flange or the upper frame element in the open state of the machine frame. The head-side cross-beam forms with its supports an integrated element of the machine frame, in which a head element of the machine frame is integrated, wherein the head element serves as an abutment for the high forces of the grinding rollers in the high pressure crushing. In order to To open men, it is provided that the head element is suspended pendulum on the upper flange of the machine frame, and to the opening, the head element is pivoted to the side and upwards.
In der deutschen Offenlegungsschrift DE 10 2007 031 879 A1 wird dieser Maschinenrahmen weiter ausgebildet, in dem die kopfseitigen Maschinenrahmen- elemente innerhalb des Tores, das durch die obere Quertraverse und die seitlichen Abstützungen gebildet wird, zur Seite geschoben werden. Die kopfseitigen Rahmenelemente werden also in der Quertraverse aufgenommen seitlich verschoben. Hierbei ergibt sich aber der Nachteil, dass die Quertraverse nicht nur so breit sein muss, dass durch die Toröffnung die Mahlwalzen mitsamt der Breite der Welle hindurchpassen. Es müssen auch noch die Breiten der zur Seite geschobenen kopfseitigen Widerlager als Maschinenrahmenelemente unter die Quertraverse passen. Dadurch wird die Rollenpresse unerwünscht breit und speziell bei einer Batterie-Anordnung, wenn im Einsatz mehrere Rollenpressen nebeneinander angeordnet sind, ist der erhöhte Raumanspruch der Rollenpressen unerwünscht. Die verlängerte Quertraverse muss dazu verstärkt werden, um die vertikalen Kräfte ohne Verformung aufnehmen zu können. In the German patent application DE 10 2007 031 879 A1 this machine frame is further formed, in which the head-side Maschinenrahmen- elements within the gate, which is formed by the upper cross member and the lateral supports are pushed to the side. The head-side frame members are therefore taken laterally displaced in the crossbeam. However, this results in the disadvantage that the cross-beam not only has to be so wide that through the door opening, the grinding rollers fit together with the width of the shaft. It must also fit the widths of the pushed aside side abutment as machine frame elements under the crossbar. As a result, the roller press is undesirably wide and especially in a battery arrangement when multiple roller presses are arranged side by side in use, the increased space requirement of the roller presses is undesirable. The extended crossbeam must be reinforced to accommodate the vertical forces without deformation.
Aufgabe der Erfindung ist es, ein Maschinenrahmen für eine Rollenpresse zur Zerkleinerung von sprödem Mahlgut zur Verfügung zu stellen, welcher leichter ist als vergleichbare Maschinenrahmen und zu einen verringerten Raumanspruch der entsprechenden Rollenpresse führt. The object of the invention is to provide a machine frame for a roller press for crushing brittle grinding material available, which is lighter than comparable machine frame and leads to a reduced space requirement of the corresponding roller press.
Die der Erfindung zu Grunde liegende Aufgabe wird dadurch gelöst, dass der Maschinenrahmen durch mindestens ein vom Maschinenrahmen und Rahmenkopf vollständig lösbares Kopfstück verschlossen ist. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. The object underlying the invention is achieved in that the machine frame is closed by at least one of the machine frame and the frame head completely detachable head piece. Further advantageous embodiments are specified in the subclaims.
Nach der Erfindung ist also vorgesehen, dass der Rahmenkopf mit seiner Quertraverse unabhängig ist vom kopfseitigen Verschluss der Rollenpresse, der als Widerlager für die hohen Kräfte in der Mahlwalze dient. Es ist anders als im Stand der Technik vorgesehen, dass die kopfseitigen Elemente bei der Demon- tage vollständig entfernt werden und nicht zur Seite und nach oben verschwenkt oder zur Seite geschoben werden. Da durch entsprechende Entwicklungen im Bereich der Maschinenrahmen für eine Rollenpresse die kopfseitigen Verschlüsse stets leichter werden, wie beispielsweise in der DE 10 2010 048 214 A1 offenbart ist, bedeutet die vollständige Entfernbarkeit des kopfseitigen Verschlusses des Maschinenrahmens weniger Zeitaufwand als das Verschwenken oder das Verschieben von sehr schweren Maschinenrahmenköpfen. According to the invention it is thus provided that the frame head with its cross-beam is independent of the head-side closure of the roller press, which serves as an abutment for the high forces in the grinding roller. It is different from the prior art that the head-end elements be completely removed and not be swung to the side and up or pushed aside. Since the corresponding developments in the field of machine frame for a roller press the head-side fasteners are always easier, as disclosed for example in DE 10 2010 048 214 A1, means the complete removability of the head-end closure of the machine frame less time than the pivoting or moving a lot heavy machine frame heads.
Nach der Erfindung ist also vorgesehen, einen leichten Maschinenrahmen mit einer Quertraverse auszustatten, welche gerade so breit ist, dass diese durch ihre Toröffnung die Mahlwalzen mitsamt der Länge der Wellen quer aufnehmen kann, so dass die Wellen die Toröffnung, die durch die obere Quertraverse und seitlichen Stützen gebildet wird, passieren können. Es ist also vorgesehen, dass die mindestens zwei seitlichen Stützen einen so großen Abstand voneinander aufweisen, dass zwischen ihnen die Mahlwalzen mit einer Länge, die sich jeweils über eine zentrale Welle erstreckt, hindurch passen. Diese Konstruktion ermöglicht einen leichteren Aufbau der Quertraverse, weil dies keine kopfseitigen Verschlüsse für den Maschinenrahmen mehr aufnehmen müssen. Die gesamte Konstruktion für den Maschinenrahmen lässt sich somit bei gleichzeitig geringer werdendem Gewicht vereinfachen. According to the invention, it is therefore intended to equip a light machine frame with a cross-beam, which is just so wide that it can accommodate the grinding rollers along with the length of the waves transversely through their door opening, so that the waves through the gate opening, through the upper cross-beam and lateral supports is formed, can happen. It is thus envisaged that the at least two lateral supports have such a large distance from each other that between them the grinding rollers with a length which extends in each case over a central shaft pass through. This design allows for easier construction of the crossbeam because this no longer needs to accommodate head-end closures for the machine frame. The entire construction for the machine frame can thus be simplified with simultaneously decreasing weight.
Wichtig für die Erfindung ist, dass das vom Maschinenrahmen vollständig lösbare Kopfstück als Verschluss des Maschinerahmens unabhängig und ohne Verbindung mit der Quertraverse ausgebildet ist. Important for the invention is that the machine frame completely detachable head piece is formed as a closure of the machine frame independently and without connection to the crossbar.
In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die Quertraverse im geschlossenen Zustand des Maschinenrahmens durch das vom Maschinenrahmen vollständig lösbare Kopfstück entlastet ist. Durch diese Art des Aufbaus kann die Quertraverse besonders leicht aufgebaut werden, weil sie kein Gewicht und keine dynamische Belastung beim Betrieb der Rollenpresse aufnehmen muss. In weitere vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass unterhalb der Quertraverse mindestens eine Schiene zum Herausfahren der Mahlwalzen angeordnet ist, wobei die Mahlwalzen jeweils in ihren Lagerböcken gelagert sind und die Lagerböcke auf der mindestens einen Schiene entlang gleiten. In an advantageous embodiment of the invention it is provided that the cross-beam is relieved in the closed state of the machine frame by the machine frame completely detachable head piece. Due to this type of construction, the crossbeam can be constructed particularly easily, because it does not have to absorb any weight and dynamic load during operation of the roller press. In a further advantageous embodiment of the invention, it is provided that at least one rail for extending the grinding rollers is arranged below the cross-beam, wherein the grinding rollers are each mounted in their bearing blocks and slide the bearing blocks on the at least one rail.
Die Erfindung wird anhand der folgenden Figuren näher erläutert. Es zeigt: The invention will be explained in more detail with reference to the following figures. It shows:
Fig. 1 eine erfindungsgemäße Rollenpresse mit Quertraverse, die unabhängig von kopfseitigen Verschlusselementen eines Maschinenrahmens ist, 1 shows a roller press according to the invention with cross-beam, which is independent of head-side closure elements of a machine frame,
Fig. 2 ein Maschinenrahmen mit skizzierter Lage der Quertraverse. Fig. 2 shows a machine frame with outlined position of the crossbeam.
In Figur 1 ist eine Rollenpresse 1 abgebildet, in welcher zwei Mahlwalzen 2 und 3 in einem Maschinenrahmen 4 aufgenommen sind. Der Maschinenrahmen 4 besteht in dieser Ausführungsform aus einem oberen, zusammenhängenden Rahmenelement 6, welches zu jeder Seite des Maschinenrahmens 4 je einen Obergurt 5 aufweist. Korrespondierend zum oberen Rahmenelement 6 ist ein unteres Rahmenelement 8 vorgesehen, welches ebenfalls zwei Untergurte 7, je eines auf einer Seite des Maschinenrahmens 4 aufweist. Die Rahmenelemente 6 und 8 bilden je mit einem hinteren Widerlager 13' und 14' (abgebildet im Bildvordergrund) und einem kopfseitigen Rahmenverschluss als Kopfstücke 13 und 14 einen geschlossenen Rahmen, der die Kräfte aufnimmt, welche die Lagerböcke 17, 18, 19 und 20 auseinander treibt. Zum Wechseln der Mahlwalzen 2, 3 ist vorgesehen, dass die Kopfelemente 13 und 14 entfernt werden und die Mahlwalzen 2, 3 mitsamt ihren Lagerböcken 17, 18, 19 und 20 nach vorne (in den Bildhintergrund) aus dem Maschinenrahmen 4 herausgeschoben werden. Wenn der Maschinenrahmen 4 ohne Kopfelemente 13, 14 und ohne Lagerböcke 17, 18, 19, 20 frei steht, bildet sich ein Öffnungsmaul aus dem oberen Rahmenelement 6 und dem unteren Rahmenelement 8, welches unter dem Eigengewicht von 5 t bis zu 10 t deformieren kann. Um das Öffnungsmaul zu stützen, ist eine Quertraverse 10 vorgesehen, die mit dem oberen Rahmenelement 6 verbunden ist und seitlich über zwei Stützen 1 1 und 12 abgestützt ist. Dabei ist die Toröffnung, die in Figur 2 deutlicher zu sehen ist, gerade so breit, das die Breite der Mahlwalzen 2 ,3 mit- samt der Welle quer durch die Toröffnung aus Quertraverse 10 und den beiden Stützen 1 1 und 12 hindurchpasst. FIG. 1 shows a roller press 1 in which two grinding rollers 2 and 3 are accommodated in a machine frame 4. The machine frame 4 in this embodiment consists of an upper, continuous frame element 6, which has an upper flange 5 on each side of the machine frame 4. Corresponding to the upper frame member 6, a lower frame member 8 is provided, which also has two lower straps 7, one on each side of the machine frame 4. The frame members 6 and 8 form each with a rear abutment 13 'and 14' (shown in the foreground) and a head-side frame closure as head pieces 13 and 14 a closed frame which receives the forces which the bearing blocks 17, 18, 19 and 20 apart drives. To change the grinding rollers 2, 3 it is provided that the head elements 13 and 14 are removed and the grinding rollers 2, 3 together with their bearing blocks 17, 18, 19 and 20 are pushed out of the machine frame 4 (in the background). When the machine frame 4 is free without head elements 13, 14 and without bearing blocks 17, 18, 19, 20, an opening mouth is formed from the upper frame element 6 and the lower frame element 8, which can deform up to 10 t under its own weight of 5 t , In order to support the mouth opening, a cross-beam 10 is provided, which is connected to the upper frame member 6 and laterally supported by two supports 1 1 and 12. In this case, the door opening, which can be seen more clearly in FIG. 2, is just so wide that the width of the grinding rollers 2, 3 can be determined. together with the shaft across the door opening of cross-beam 10 and the two supports 1 1 and 12 passes.
In Figur 2 ist die Quertraverse 10 mit den beiden Stützen 1 1 und 12 in einer Ansicht von vorn dargestellt, wobei weitere Elemente des Maschinenrahmens 4 nur noch schemenhaft dargestellt sind. In der Abbildung ragt die Quertraverse 10 auf der im Bild linken Seite weiter über den Maschinenrahmen 4 hinaus als auf der rechten Seite im Bild, um die auf dieser Seite verlängerten Wellenstumpfe der Mahlwalzen 2, 3 passieren zu lassen. Um die Mahlwalzen 2, 3 durch die Toröffnung aus Quertraverse 10 und en seitlichen Stützen 1 1 und 12 passieren zu lassen, ist es in Ausgestaltung der Erfindung vorgesehen, dass mindestens eine Schiene 15 und 16 vorahnden sind, über welche die Lagerböcke 17, 18, 19 und 20 gleiten bis zur Aufnahme, beispielsweise durch einen Kran, gleiten können. In Figure 2, the cross-beam 10 is shown with the two supports 1 1 and 12 in a front view, with other elements of the machine frame 4 are shown only schematically. In the figure, the cross-beam 10 protrudes on the left side of the image beyond the machine frame 4 than on the right side in the image to allow the extended on this page Wellenstumpfe the grinding rollers 2, 3 happen. In order to allow the grinding rollers 2, 3 to pass through the gate opening made of cross-beam 10 and lateral supports 1 1 and 12, it is provided in an embodiment of the invention that at least one rail 15 and 16 are anticipated, via which the bearing blocks 17, 18, Slide 19 and 20 to take up, for example, by a crane, can slide.
