Description

Aufgabevorrichtung für eine Hochdruckrollenpresse  Feeding device for a high-pressure roller press
Die Erfindung betrifft eine Aufgabevorrichtung für eine Hochdruckrollenpresse zur Hockdruckzerkleinerung von Mahlgut, welche das Mahlgut kontrolliert in einen Walzenspalt zwischen zwei Walzen der Hochdruckrollenpresse aufgibt. The invention relates to a feeding device for a high-pressure roller press for Hockdruckzerkleinerung of ground material, which controls the material to be ground in a nip between two rollers of the high-pressure roller press gives up.
Für die Zerkleinerung von sprödem Mahlgut wurde 1 977 von Schönert in der Schrift DE 27 08 053 vorgeschlagen, das Mahlgut nicht klassisch zu zermahlen, sondern dieses in einem ersten Verfahrensschritt durch Hochdruckbeanspruchung in einem Walzenspalt zu sogenannten Schülpen zu pressen, wobei das Gefüge des Mahlgutes zerbricht und dadurch in viele kleine Bruchstücke zerteilt wird . Die Schülpen werden in einem weiteren Schritt in ihre Einzelbestandteile zerlegt. Das Pressen unter hohem Druck im Walzenspalt und das anschließende Desagglomerieren der verpressten Schülpen beansprucht weniger Energie als das herkömmliche Mahlverfahren, bei dem die Zerkleinerung durch Scheren oder Reiben passiert. Mit der Zerkleinerung von Mahlgut mittels Hochdruckbeanspruchung in einem Walzenspalt werden hohe Mahlfeinheiten erreicht, wenn ein entsprechender Umlauf des Mahlgutes gewährleistet ist.  For the comminution of brittle grinding material 1 977 was proposed by Schönert in the document DE 27 08 053, not grind the ground material, but to press this in a first step by high pressure in a nip to so-called slugs, the structure of the material to be ground breaks and thereby broken up into many small fragments. The slugs are decomposed in a further step into their individual components. Pressing under high pressure in the nip and then deagglomerating the compressed slugs requires less energy than the conventional grinding process, in which the comminution by shearing or rubbing happens. With the comminution of material to be ground by high-pressure loading in a nip high Mahlfeinheiten be achieved if a corresponding circulation of the ground material is guaranteed.
Der Walzenspalt ist breiter als die größte Ausdehnung des zerkleinerten Mahlgutes. Es ist erforderlich, den Walzenspalt so mit Mahlgut zu beschicken, dass kontinuierlich eine bestimmte Menge des Mahlgutes den Walzenspalt passieren kann . Denn wird der Walzenspalt mit einer zu geringen Menge Mahlgut pro Zeiteinheit beschickt, so wird im Extremfall das Mahlgut nicht mehr zerkleinert oder die Hochdruckrollenpresse wirkt ähnl ich einem Brecher. Wird hingegen eine zu große Menge Mahlgut auf den Wal- zenspalt gegeben, kann die Hochdruckrollenpresse überlastet werden mit der Folge, dass sie zu vibrieren anfängt. Bei der Vibration vergrößert und verkleinert sich der Walzenspalt in Resonanzfrequenz und auch die Umlaufgeschwindigkeit variiert mit Resonanzfrequenz, da bei einer Überlastung die Walzen wiederkehrend durch das in zu hohem Maße vorhandene Mahlgut gebremst und durch die Antriebsmotoren wieder beschleunigt werden . Daher ist bei der Hochdruckzerkleinerung im Walzenspalt dafür Sorge zu tragen, dass der Walzenspalt in geeignetem Maße mit Mahlgut beaufschlagt wird . The nip is wider than the largest extent of the comminuted material to be ground. It is necessary to feed the nip with millbase so that a certain amount of the ground material can continuously pass through the nip. Because if the nip is loaded with too little amount of material to be ground per unit of time, in extreme cases the material to be ground is no longer comminuted or the high-pressure roller press acts like a crusher. If, on the other hand, too large an amount of regrind is added to the Given the crevice, the high-pressure roller press can become overloaded with the result that it begins to vibrate. During vibration, the nip increases and decreases in resonant frequency and the rotational speed varies with resonant frequency, since in an overload, the rollers are repeatedly braked by the existing too large ground material and accelerated by the drive motors again. Therefore, in the high-pressure crushing in the nip is to ensure that the nip is applied to a suitable extent with millbase.
Die Aufgabemenge hängt stark von der Beschaffenheit des Mahlgutes ab. Die hierbei zu beachtenden Parameter sind die Korngrößenverteilung, die mittlere Korngröße und die Gleichmäßigkeit des zur Verfügung stehenden Mahlgutstromes auf den Walzenspalt. Das Mahlgut sollte gleichmäßig von oben in den Walzenspalt geführt werden .  The amount of feed depends heavily on the nature of the material to be ground. The parameters to be considered here are the particle size distribution, the average particle size and the uniformity of the available ground material flow onto the nip. The material to be ground should be fed evenly from above into the nip.
Die aufgegebene Materialmenge hat wesentlichen Einfluss auf den angestrebten ruhigen Lauf der Hochdruckrollenpresse. Zur Verbesserung der Einzugsverhältnisse und um eine gleichmäßige Verteilung der Antriebsleistung auf die Antriebsmotoren der Hochdruckrollerpresse zu sichern, wurde die Dosier-Funktion der Aufgabevorrichtung über dem Walzenspalt stetig verbessert. The amount of material dispensed has a significant influence on the desired smooth running of the high-pressure roller press. To improve the intake conditions and to ensure a uniform distribution of the drive power to the drive motors of the high-pressure roller press, the metering function of the feeder over the nip has been steadily improved.
Im Stand der Technik sind Aufgabevorrichtungen bekannt, die den gleichmäßigen Zufluss des Mahlgutes regeln .  In the prior art feeding devices are known which regulate the uniform inflow of the ground material.
So offenbart die Schrift WO 201 0/003850 eine Aufgabevorrichtung, mit der das Mahlgut kontrolliert in den Walzenspalt zwischen zwei Walzen geführt wird, wobei die Aufgabevorrichtung mindestens zwei Drehschieber aufweist, durch welche bei symmetrischer Stellung eine bestimmte mittlere Gesamtmenge pro Zeiteinheit auf die Hochdruckrollerpressen aufgegeben werden kann . Thus, document WO 201 0/003850 discloses a feeding device with which the material to be ground is guided in a controlled manner into the nip between two rollers, wherein the feeding device has at least two rotary valves, through which at symmetrical position a certain middle Total amount per unit time can be placed on the high-pressure roller presses.
Das Einzugsverhalten wird ebenso von der Materialschüttung im Raum über den Walzen beeinflusst. Unter Materialschüttung (Schüttmenge) ist eine Anhäufung bzw. ein Volumen einer Mahlgutmenge im Raum oberhalb der Kompaktionszone zu verstehen . Die optimale Materialschüttung wird durch die Parameter Korngröße des Mahlgutes, Feuchte und den Schüttwinkel bestimmt.  The intake behavior is also influenced by the material bed in the room above the rollers. Bulk material (bulk) is an accumulation or volume of Mahlgutmenge in the space above the compaction zone to understand. The optimum material fill is determined by the parameters grain size of the material to be ground, humidity and the angle of repose.
Es besteht ein Bedürfnis dafür, eine optimale Materialschüttung auf den Walzen einstellen zu können .  There is a need to be able to set an optimal material bed on the rollers.
Aufgabe der Erfindung ist es daher, eine Aufgabevorrichtung anzugeben, mit der die Einstellung einer definierten Materialschüttung erreicht werden kann .  The object of the invention is therefore to provide a feeding device with which the setting of a defined material bed can be achieved.
Die Aufgabe wird mit einer Aufgabevorrichtung mit den Merkmalen des Anspruches 1 gelöst.  The object is achieved with a feeding device with the features of claim 1.
Die erfindungsgemäße Aufgabevorrichtung für eine Hochdruckrollenpresse zur Hochdruckzerkleinerung von Mahlgut, welche das Mahlgut kontrolliert in einen Walzenspalt zwischen zwei Walzen der Hochdruckrollenpresse aufgibt, ist dadurch gekennzeichnet, dass die Aufgabevorrichtung wenigstens eine Materialaufgabe mit einer vertikal verstellbaren Materialrutsche und eine Materialüberlaufeinrichtung aufweist.  The feed device according to the invention for a high-pressure roller press for high-pressure comminution of millbase, which gives the millbase controlled in a nip between two rollers of the high-pressure roller press is characterized in that the feeding device has at least one material feed with a vertically adjustable material chute and a material overflow device.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Aufgabevorrichtung sind in den Unteransprüchen angegeben .  Further advantageous embodiments of the feeding device according to the invention are specified in the subclaims.
Mit der erfindungsgemäßen Aufgabevorrichtung lässt sich eine definierbare Materialschüttung im Raum zwischen Walzenspalt und der Materialrutsche einstellen . Die Aufgabevorrichtung ist an einer Stützvorrichtung am Maschinenahmen der Hochdruckrollenpresse angeordnet. Die Materialaufgabe ist als trichterartiges Gehäuse mit einer Führung für eine Materialrutsche ausgebildet. Die Materialaufgabe ist mittig über einen Teil der Walzen und dem Walzenspalt angeordnet. Sie dient einerseits der Führung des zu mahlenden Materials entlang eines Materialbeschickungsbereiches auf den Walzen bis hin zum Walzenspalt und andererseits auch als Staubsammler. Zu diesem Zweck sind Entstaubungsleitungen vorgesehen . Die Materialrutsche wird in einer Führung der Materialaufgabe geführt. With the loading device according to the invention, a definable material bed in the space between the nip and the material chute can be adjusted. The feeder is arranged on a support device on the machine frame of the high-pressure roller press. The material task is designed as a funnel-like housing with a guide for a material slide. The material feed is arranged centrally over a part of the rolls and the nip. On the one hand, it serves to guide the material to be ground along a material feed area on the rolls up to the nip and on the other hand also as a dust collector. Dedusting lines are provided for this purpose. The material chute is guided in a guide of the material task.
Erfindungswesentlich ist die in der Materialaufgabe geführte höhenverstellbare Materialrutsche, die die Einstellung einer Materialschüttung ermögl icht.  Essential to the invention is guided in the material task height-adjustable material chute, which allows the setting of a bulk material ermögl.
In einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Materialrutsche wenigstens aus einem Schacht mit einem Materialein- lass und einem Materialaustritt gebildet ist, der Schacht in einer Führung der Materialaufgabe geführt und die Materialrutsche über eine Versteileinrichtung über dem Walzenspalt vertikal verstellbar ist.  In a preferred embodiment of the invention, it is provided that the material chute is formed at least from a chute with a material inlet and a material outlet, the chute is guided in a guide of the material feed and the material chute is vertically adjustable via an adjusting device above the roll gap.
Die Materialrutsche besteht aus einem quaderförmigen Schacht, mit einer Öffnung für den Materialeinlass und einer Öffnung für den Materialaustritt. Der Schacht wird über die Führung in der Materialaufgabe geführt. Zur Höhenverstellung der Materialrutsche ist eine geeignete Versteileinrichtung, beispielsweise eine Hydraulikeinrichtung, vorgesehen .  The material chute consists of a cuboidal shaft, with an opening for the material inlet and an opening for the material outlet. The shaft is guided over the guide in the material task. For height adjustment of the material slide a suitable adjusting device, for example a hydraulic device is provided.
Die Materialrutsche kann über ein Hydraulikeinrichtung höhenverstellt werden, wobei die Hydraulikeinrichtung mit der Stützvorrichtung und dem Schacht der Materialrutsche in Verbindung steht und am Schacht angreift. Eine andere bevorzugte Ausführung der Erfindung sieht vor, dass die Materialrutsche derart in der Materialaufgabe angeordnet ist, dass das Mahlgut mittig über dem Walzenspalt auf die Walzen der Hochdruckrollenpresse abgebbar ist. The material chute can be adjusted in height via a hydraulic device, wherein the hydraulic device with the support device and the shaft of the material chute is in communication and engages the shaft. Another preferred embodiment of the invention provides that the material chute is arranged in the material feed such that the material to be ground can be dispensed centrally above the nip onto the rolls of the high-pressure roller press.
Dazu ist Materialrutsche innerhalb der Aufgabevorrichtung so angeordnet, dass der Schacht bzw. Materialeinlass und Materialauslass jeweils mittig über dem Walzenspalt liegen und der Schacht mittig über diesem in der Höhe verstellt werden kann . Damit wird eine gleichmäßige Aufgabe des Mahlgutes gewährleistet.  For this purpose, material chute within the feeder is arranged so that the shaft or material inlet and material outlet are each centrally above the nip and the shaft can be adjusted centrally above this in height. This ensures a uniform task of the ground material.
In einer nächsten bevorzugten Ausführungsform der Erfindung ist erfindungsgemäß vorgesehen, dass die Materialrutsche derart vertikal verstellbar ist, dass der Materialaustritt von einer oberen Position bis zu einer unteren Position und umgekehrt verfahrbar ist.  In a next preferred embodiment of the invention, it is provided according to the invention that the material chute is vertically adjustable such that the material outlet can be moved from an upper position to a lower position and vice versa.
Die Materialschüttung ist die Materialmenge, die über einen bestimmten Bereich, den Materialbeschickungsbereich, auf den Walzen aufgegeben wird . Unter freier Materialschüttung oder freier Mahlgutschüttung ist eine lose Anhäufung bzw. ein Volumen einer Materialmenge bzw. des Mahlgutes zu verstehen, das sich im Raum oberhalb der Kompaktionszone bis zum Materialaustritt der Materialrutsche ausbildet. Die Anhäufung kann im Idealfall eine kegelstumpfartige Form annehmen .  The material bed is the amount of material that is deposited on the rollers over a certain area, the material feed area. Under free bed of material or free Mahlgutschüttung is a loose accumulation or volume of a quantity of material or the ground material to be understood, which forms in the space above the Kompaktzone to the material outlet of the material slide. The aggregate may ideally assume a frustoconical shape.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass sich bei Stellung des Materialaustrittes in der oberen Position eine höchste freie Materialschüttung ausbildet.  A further preferred embodiment of the invention provides that when the material outlet is in the upper position, a maximum free bulk of material is formed.
Die Materialrutsche kann stufenlos oberhalb des Walzenspaltes über die Versteileinrichtung höhenverstellt werden . Die höchste Verstellung ist erreicht, wenn der Materialaustritt eine Position I I über dem Walzenspalt einnimmt. Die niedrigste Verstellung wird durch die Position I markiert. Hier befindet sich der Materialaustritt direkt zwischen den Walzen . The material chute can be adjusted in height continuously above the nip via the adjusting device. The highest adjustment is achieved when the material exit a position II above the nip occupies. The lowest adjustment is marked by the position I. Here is the material outlet directly between the rollers.
Wird die Materialrutsche in ihre höchste Verstellposition über dem Walzenspalt gefahren, bildet sich im Raum über dem Walzenspalt und dem Materialaustritt eine höchste freie Materialschüttung aus. In dieser Position ist die größtmögliche Materialbeschickung auf den Walzen erreichbar. If the material slide is moved to its highest adjustment position above the nip, a maximum free bulk of material forms in the space above the nip and the material outlet. In this position, the largest possible material loading on the rollers can be achieved.
Die freie Materialschüttung lässt sich erfindungsgemäß in Abhängigkeit von der über die Versteileinrichtung einstellbaren Höhe der Materialrutsche regul ieren . Die freie Materialschüttung verringert sich, wenn die Materialrutsche in Richtung Walzenspalt nach unten gefahren wird und geht gegen Null , wenn die Materialrutsche in Position I gefahren wird . According to the invention, the free material bed can be regulated as a function of the height of the material chute which can be adjusted via the adjusting device. The free bulk material decreases as the material chute is driven down towards the nip and approaches zero when the material chute is moved to position I.
Eine nächste bevorzugte Ausführungsform der Erfindung sieht vor, dass sich bei Stellung des Materialaustrittes in der unteren Position keine freie Materialschüttung ausbildet. A next preferred embodiment of the invention provides that in the position of the material outlet in the lower position no free material bed forms.
Wird hingegen die Materialrutsche in ihre niedrigste Verstellposition gefahren, kann sich keine freie Materialschüttung im Raum über dem Walzenspalt und dem Materialaustritt der Materialrutsche bilden . Das Mahlgut gelangt über die Materialrutsche direkt in die Kompaktionszone und in den Walzenspalt. Auf die Walzen wird die kleinste Materialmenge aufgegeben . If, on the other hand, the material chute is moved to its lowest adjustment position, no free bulk material can form in the space above the nip and the material outlet of the material chute. The material passes through the material chute directly into the compaction zone and into the nip. On the rollers, the smallest amount of material is given up.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass die Mahlgutüberlaufeinrichtung aus einer ersten Überlaufrutsche und einer zweiten Überlaufrutsche gebildet ist, wobei die Überlaufrutschen an der Materialaufgabe oder an der Materialrutsche fest oder lösbar angeordnet sind . A further preferred embodiment of the invention provides that the Mahlgutüberlaufeinrichtung is formed of a first overflow chute and a second overflow chute, wherein the overflow chutes are fixed or detachably arranged on the material task or on the material chute.
Die erfindungsgemäße Aufgabenvorrichtung weist zur kontinuierl ichen Nachbefüllung mit Mahlgut und der Kontrolle des Füllstandes des nachzu- gebenden Mahlgutes im Schacht der Materialrutsche, wie auch in der Materialaufgabe selbst, eine Mahlgutüberlaufeinrichtung auf. Die Mahlgutüberlaufeinrichtung kann zwei Überlaufrutschen vorsehen, welche vorzugsweise jeweils an den gegenüberliegenden Schachtwänden der Materialrutsche fest oder wiederlösbar angebracht sind . Die Überlaufrutschen können röhrenartig ausgebildet sein und vorzugsweise bis etwa in Höhe zum Walzenspalt reichen . The task device according to the invention has for the continuous refilling with regrind and the control of the level of the nach- Grinding material in the chute of the material chute, as well as in the material task itself, a Mahlgutüberlaufeinrichtung on. The Mahlgutüberlaufeinrichtung may provide two overflow chutes, which are preferably fixed or detachably mounted respectively on the opposite shaft walls of the material chute.
