Abstract

The device has two rotatable crusher rollers (3,4) whereby one is movable and can be moved to a different height from the other fixed roller (3). An opening (15) is simultaneously released in the machine stand (1) to discharge the material which cannot be crushed. The rotary direction of at least one roller is reversed at least once for this ejection. The ends of the movable roller are mounted in slide blocks which are displaceable in parallel slits in the machine stand. The slide blocks are guided by lift elements (7) into a position where a steep plane (E-E) containing the axes (A,B) of the two rollers is formed with the movable roller lower. The opening is provided on the side of the roller remote from the rolling gap.

Description

Die Erfindung betrifft eine Vorrichtung zum Grobzerkleinern keramischer Massen, mittelharter Gesteine oder dergleichen, mit zwei in einem Maschinenständer drehbar gelagerten Messerwalzen, die je von einem eigenen, reversierbaren Antrieb antreibbar sind und deren Walzenspalt durch Parallelverschiebung einer Walze zu sich selbst einstellbar ist.The invention relates to a device for coarse comminution of ceramic masses, medium-hard rocks or the like, with two knife rollers rotatably mounted in a machine stand, each of which can be driven by its own, reversible drive and the roller gap of which can be adjusted by shifting a roller parallel to itself.

Bei bekannten Vorrichtungen dieser Art (Prospekt "Brechen, Zerkleinern, Aufbereiten" der Firma Rieter-Werke Händle KG, Juli 1989) reversieren die Antriebe die Walzen dann, wenn ein Materialbrocken oder Stein aufgrund seiner Größe oder Härte nicht ohne weiteres zerkleinert werden kann. Der Reversiervorgang wird bei Überschreiten eines vorgegebenen Antriebsdrehmomentes automatisch eingeleitet. Durch den Reversierbetrieb wird das übergroße Materialstück in eine andere Lage befördert. Dann werden die Walzen erneut in Gegenrichtung, d.h. in Zerkleinerungsrichtung angetrieben.In known devices of this type (brochure "breaking, crushing, processing" from Rieter-Werke Handel KG, July 1989), the drives reverse the rollers when a chunk of material or stone cannot be easily shredded due to its size or hardness. The reversing process is initiated automatically when a specified drive torque is exceeded. The oversize piece of material is transported to a different position by the reversing operation. Then the rollers are driven again in the opposite direction, ie in the direction of comminution.

Wenn ein mehrmaliges Rerversieren der Antriebe nicht zur Zerkleinerung des Materialstückes führt, bleibt die Vorrichtung stehen. Dann muß das Materialstück aus der Vorrichtung entfernt werden. Ein solches Entfernen ist aufgrund der schlechten Zugänglichkeit des Arbeitsbereiches der Vorrichtung nur über den Beschickungsbereich möglich und je nach Größe des den Zerkleinerungsvorgang hemmenden Materialstückes sehr zeitaufwendig. Während der Stillstandszeit ist die Maschine zum Zerkleinern nicht nutzbar. Außerdem ist es für eine Bedienungsperson höchst gefährlich, manuell in den Arbeitsbereich der Vorrichtung einzugreifen, wie dies bei manchen Maschinen zum Entfernen übergroßer Materialstücke erforderlich ist.If repeated reversing of the drives does not lead to comminution of the piece of material, the device stops. Then the piece of material must be removed from the device. Because of the poor accessibility of the working area of the device, such removal is only possible via the loading area and, depending on the size of the piece of material that inhibits the size reduction process, is very time-consuming. The machine cannot be used for shredding during downtime. In addition, it is extremely dangerous for an operator to manually intervene in the work area of the device, as is required in some machines to remove oversized pieces of material.

Es sind Vorrichtungen zur automatischen Entfernung nicht zerkleinerbarer Materialstücke bekannt geworden, die beispielsweise rechenartige, schwenkbare Auswurfeinrichtungen verwenden. Solche Auswurfeinrichtungen können jedoch nur dann eingesetzt werden, wenn die Messerwalzen einen so großen Abstand zueinander einhalten, daß sich die von den Walzen abstehenden Messer, welche hier exakt einander gegenüberliegend anzuordnen sind, nicht berühren. Der Zerkleinerungsgrad ist bei einem derartig großen Walzenabstand bzw. Walzenspalt begrenzt. Die einzelnen Rechenstäbe einer solchen Auswurfeinrichtung liegen im Betrieb in zwischen Messerscheiben der Walzen ausgebildeten Walzennuten und hemmen so den Durchgang des zu brechenden Materials. Im Betrieb können sich die Walzennuten mit dem zu zerkleinernden Material füllen, was neben einer Verschlechterung der Zerkleinerungswirkung zu Funktionsstörungen und Beschädigung der Rechenstäbe führen kann.Devices for automatically removing pieces of material that cannot be shredded have become known, which use, for example, rake-like, pivotable ejection devices. However, such ejection devices can only be used if the knife rollers keep such a large distance from one another that the knives protruding from the rollers, which are to be arranged exactly opposite one another, do not touch. The degree of comminution is limited with such a large roll spacing or roll gap. During operation, the individual rake bars of such an ejection device lie in roller grooves formed between the cutter disks of the rollers and thus inhibit the passage of the material to be crushed. In operation, the roller grooves can fill with the material to be shredded, which in addition to a deterioration in the shredding effect can lead to malfunctions and damage to the rake bars.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß automatisch nicht zerkleinerbare Materialstücke ausgeworfen werden können, wobei ein Stillsetzen der Vorrichtung und ein Sicherheitsrisiko vermieden sind.The invention has for its object to design a device of the type mentioned in such a way that pieces of material that cannot be comminuted can be automatically ejected, thereby stopping the device and avoiding a safety risk.

Zur Lösung dieser Aufgabe dient Patentanspruch 1.Claim 1 serves to achieve this object.

Bei der Vorrichtung gemäß der Erfindung wird mit dem Verändern der Höhenlage, insbesondere Tieferstellen der beweglichen Walze parallel zu sich selbst, gleichzeitig und automatisch das Freigeben einer seitlichen Öffnung im Maschinenständer und Reversieren mindestens einer Walze und Auswerfen eines nicht zerkleinerbaren Material stückes durch die Öffnung bewirkt, ohne daß die Vorrichtung angehalten werden muß und ohne daß eine Bedienungsperson manuell eingreifen muß.In the device according to the invention, by changing the height, in particular lowering the movable roller parallel to itself, at the same time and automatically the opening of a side opening in the machine stand and reversing at least one roller and ejecting a piece of material which cannot be comminuted through the opening is effected, without stopping the device and without manual intervention by an operator.

Bei einer vorteilhaften Ausgestaltung der Erfindung ist zum Freigeben und Absperren der Öffnung eine Klappe am Maschinenständer angeordnet, deren Öffnungs- und Schließbewegung mit der Absenk- und Hubbewegung von Hubelementen zum Verschieben der beweglichen Walze gekoppelt ist, vorzugsweise mechanisch über einen Hebelmechanismus, der beim Absenken der beweglichen Walze die Klappe öffnet und beim Anheben in die normale Betriebslage wieder schließt.In an advantageous embodiment of the invention, a flap is arranged on the machine stand for releasing and blocking the opening, the opening and closing movement of which is coupled with the lowering and lifting movement of lifting elements for displacing the movable roller, preferably mechanically via a lever mechanism which, when the movable roller opens the flap and closes again when it is raised to the normal operating position.

Die Betätigungsmittel für das Auf- und Zustellen der Klappe können auch unabhängig von den Hubelementen zum Verschieben der Walze vorgesehen sein, beispielsweise in Gestalt von separaten elektromechanischen, hydraulischen oder pneumatischen Hubelementen.The actuating means for opening and closing the flap can also be provided independently of the lifting elements for displacing the roller, for example in the form of separate electromechanical, hydraulic or pneumatic lifting elements.

Um eine Reinigung der zwischen den einzelnen Messerscheiben jeder Walze vorgesehenen Walzennuten zu erzielen und damit die Zerkleinerungswirkung zu verbessern, sind die Messerscheiben axial auf den beiden Walzen so zueinander versetzt angeordnet, daß die Messer der einen Walze den Walzennuten der anderen Walze gegenüberstehen, so daß die Messer in die Walzennuten der jeweils anderen Walze eingreifen können.In order to achieve cleaning of the roller grooves provided between the individual cutter disks of each roller and thus to improve the crushing effect, the cutter disks are axially offset on the two rollers so that the knives of one roller follow the roller grooves face the other roller so that the knives can engage in the roller grooves of the other roller.

Gemäß den Figuren sind zwei Messerwalzen 3,4 achsparallel in parallelen Schenkeln 11, 12 eines U-förmigen Maschinenständers 1 gelagert und mit Messern 5 versehen, die auf ringförmigen Messerscheiben 31,41 radial und axial spiralförmig ausgerichtet sind und in Umfangsrichtung gegensinnig weisende Messerschneiden haben. Die Messerscheiben 31,41 sind durch Abstandsringe getrennt, welche Walzennuten 51 bilden.According to the figures, two knife rollers 3, 4 are mounted axially parallel in parallel legs 11, 12 of a U-shaped machine stand 1 and are provided with knives 5, which are radially and axially spirally aligned on ring-shaped knife disks 31, 41 and have knife edges pointing in opposite directions in the circumferential direction. The knife disks 31, 41 are separated by spacer rings which form roller grooves 51.

Jede Walze 3,4 wird von einem separaten Motor 2 hydraulisch, elektromechanisch oder pneumatisch angetrieben.Each roller 3, 4 is driven hydraulically, electromechanically or pneumatically by a separate motor 2.

Die Walze 4, die über Kulissensteine 42 in parallelen radialen, vertikalen oder schrägen Schlitzen 13 in den Schenkeln 11,12 verschiebbar ist, läßt sich mittels zweier Hubelemente 7, wie Hydraulikzylinder, Spindelhubelemente, Pneumatikzylinder oder ähnliche Elemente, relativ zur anderen feststehenen Walze 3 heben und senken. Dadurch läßt sich der Walzenspalt s stufenlos einstellen.The roller 4, which is displaceable in sliding blocks 42 in parallel radial, vertical or oblique slots 13 in the legs 11, 12, can be lifted relative to the other fixed roller 3 by means of two lifting elements 7, such as hydraulic cylinders, spindle lifting elements, pneumatic cylinders or similar elements and lower. This leaves the roll gap s is infinitely variable.

Auf einer Seite der Maschine ist zwischen den Schenkeln 11, 12 eine Klappe 8 um ein Scharnier 81 schwenkbar gelagert, welche über einen Hebelmechanismus 6 mit der beweglichen Walze 4 verbunden sein oder durch separate hydraulische, pneumatische, mechanische oder elektromechanische Hubelemente je nach Bedarf geöffnet oder geschlossen werden kann.On one side of the machine, a flap 8 is pivotally mounted between the legs 11, 12 about a hinge 81, which are connected to the movable roller 4 via a lever mechanism 6 or opened or, as required, by separate hydraulic, pneumatic, mechanical or electromechanical lifting elements can be closed.

Im normalen Zerkleinerungsbetrieb drehen die Messerwalzen 3,4 in den Pfeilrichtungen in Fig. 1 und 2 gegenläufig.In normal shredding operation, the knife rollers 3, 4 rotate in opposite directions in the arrow directions in FIGS. 1 and 2.

Blockieren die Messerwalzen aufgrund eines zu großen oder zu harten Materialstückes M, wird die Drehrichtung der Walzen 3,4 mehrmals reversiert, um das Materialstück zu lösen, in eine andere Lage zu drehen und zu brechen.If the knife rollers block due to a piece of material M that is too large or too hard, the direction of rotation of the rollers 3, 4 is reversed several times in order to loosen the piece of material, rotate it into a different position and break it.

Führt dieses Arbeitsbeispiel nicht zum Erfolg, muß dieses Materialstück M ausgesondert werden. Dann wird die bewegliche Walze 4 gemäß den Figuren 3 und 4 automatisch von den Hubelementen 7 abgesenkt, bis die Achsen A-A, B-B der beiden Walzen in einer unter dem Winkel β nach unten geneigten schiefen Ebene E-E liegen.If this working example does not lead to success, this piece of material M must be discarded. The movable roller 4 is then automatically lowered by the lifting elements 7 according to FIGS. 3 and 4 until the axes A-A, B-B of the two rollers lie in an inclined plane E-E which is inclined downwards at an angle β.

Dabei wird über den Hebelmechanismus 6 mit dem Absenken der Walze 4 automatisch die Klappe 8 hochgeschwenkt, um eine seitliche Öffnung 15 im Maschinenständer freizugeben.When the roller 4 is lowered, the flap 8 is automatically pivoted upward via the lever mechanism 6 in order to open a lateral opening 15 in the machine stand.

Beide Walzen 3 und 4 drehen nun gleichsinnig in Richtung der Öffnung 15 und werfen somit das nicht zerkleinerbare Materialstück aus der Maschine in einen Behälter oder auf ein Transportband aus.Both rollers 3 and 4 now rotate in the same direction in the direction of the opening 15 and thus throw the piece of material that cannot be comminuted out of the machine into a container or onto a conveyor belt.

Ist die Maschine entleert, wird die Walze 4 durch die Hubelemente 7 angehoben, bis der gewünschte kleine Walzenspalt s wieder erreicht ist. Über den Hebelmechanismus 6 verschließt gleichzeitig die seitliche Klappe 8 die Öffnung 15; die Maschine ist erneut betriebsbereit.If the machine is emptied, the roller 4 is raised by the lifting elements 7 until the desired small roller gap s is reached again. Via the lever mechanism 6, the side flap 8 simultaneously closes the opening 15; the machine is ready for operation again.

Anstelle der beschriebenen mechanischen Koppelung der Klappenbewegung mit der Hub- und Absenkbewegung der Walze 4 kann auch eine separate elektromechanische oder druckmittelbetätigte Steuerung der Klappenbewegung abhängig vom Hub der Walze 4 vorgesehen sein.Instead of the mechanical coupling of the flap movement described with the lifting and lowering movement of the roller 4, a separate electromechanical or pressure-medium-operated control of the flap movement depending on the stroke of the roller 4 can also be provided.

Zur Erzielung eines höchstmöglichen Zerkleinerungsgrades kann der Messerwalzenspalt s so klein sein, daß sich die Messerscheiben 31, 41 nahezu berühren, wobei die Messer 5 der einen Messerwalze in die Walzennuten 51 der anderen Messerwalze wechselseitig eingreifen. Eine solche minimale Einstellung des Walzenspaltes s führt zu einer Reinigung der Walzennuten 51 und damit zu einer Verbesserung der Zerkleinerungswirkung.To achieve the highest possible degree of comminution, the knife roller gap s can be so small that the knife disks 31, 41 almost touch, the knives 5 of one knife roller mutually engaging in the roller grooves 51 of the other knife roller. Such a minimal setting of the roller gap s leads to a cleaning of the roller grooves 51 and thus to an improvement in the size reduction effect.

Die beschriebene Vorrichtung ermöglicht ein vollautomatisches Aussondern von nicht zerkleinerbaren Materialstücken M unter Vermeidung langer Stillstandszeiten und manueller Tätigkeiten und eine Einstellung des Walzenspaltes s auf einen Minimalwert, was eine effektive Reinigung der Walzennuten 51 durch die Messer 5 bewirkt und die Zerkleinerungswirkung optimiert.The device described enables a fully automatic rejection of material pieces M that cannot be comminuted, avoiding long downtimes and manual activities, and setting the roller gap s to a minimum value, which effects an effective cleaning of the roller grooves 51 by the knives 5 and optimizes the comminution effect.
