Description

Die Erfindung betrifft ein Verfahren zum Kühlen von Klinker.The invention relates to a method for cooling clinker.

Aus der DE 43 34 901 A1 ist ein Rostkühler mit einem ersten Kühlerabschnitt, einem zweiten Kühlerabschnitt und einem dazwischen angeordneten Brecher bekannt.From the DE 43 34 901 A1 For example, a grate cooler is known having a first radiator section, a second radiator section, and a crusher disposed therebetween.

Bei der in der DE 44 14 292 A1 beschriebenen Anlage zum Kühlen von Weißzementklinker schließt sich an den Drehrohrofen ein erstes und ein zweites Kühlaggregat an, wobei im ersten Kühlaggregat eine Zerkleinerungsvorrichtung angeordnet ist. Am unteren Ende des ersten Kühlaggregats ist ferner eine Abzugsvorrichtung für den Abzug von ggf. anfallendem, zu schwach gebranntem Klinker vorgesehen.When in the DE 44 14 292 A1 described plant for cooling white cement clinker joins the rotary kiln, a first and a second cooling unit, wherein in the first cooling unit, a crushing device is arranged. At the lower end of the first cooling unit, a trigger device for the deduction of possibly accumulating, too weak burned clinker is also provided.

Um eine möglichst gleichbleibende Qualität des Klinkers zu gewährleisten, werden Proben des Klinkers genommen und untersucht. In Abhängigkeit des Ergebnisses kann dann Einfluss auf die Rohmehlzusammensetzung, die Brennstoffregelung, etc. genommen werden. Aufgrund der hohen Temperaturen des aus dem Ofen kommenden und auf den Kühler fallenden Klinkers können derartige Proben nur hinsichtlich ihrer chemischen Eigenschaften untersucht werden. Die Bildung der Klinkermineralien ist erst dann abgeschlossen, wenn die Temperatur des Klinkers unter etwa 720 °C fällt.In order to ensure a constant quality of the clinker, samples of the clinker are taken and examined. Depending on the result, it is then possible to influence the raw meal composition, the fuel control, etc. Due to the high temperatures of the coming out of the oven and on the cooler clinker such samples can only be examined in terms of their chemical properties. The formation of the clinker minerals is completed only when the temperature of the clinker falls below about 720 ° C.

Um den Klinker sowohl hinsichtlich seiner chemischen als auch hinsichtlich seiner mineralogischen Eigenschaften zu analysieren, wird im Stand der Technik erwähnt, die Probennahme nach dem Kühler vorzunehmen. Bedingt durch die relativ lange Verweilzeit des Klinkers im Kühler kann ein Eingriff in die vorhergehenden Verfahrensabschnitte nur mit erheblichem Zeitverlust vorgenommen werden.In order to analyze the clinker in terms of both its chemical and its mineralogical properties, it is mentioned in the prior art to take the sample after the cooler. Due to the relatively long residence time of the clinker in the cooler, an intervention in the preceding process sections can be made only with considerable loss of time.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Kühlen von Klinker anzugeben, so dass umfassende Informationen über die Eigenschaften des Klinkers möglichst zeitnah erfasst werden können.The invention is therefore based on the object of specifying a method for cooling clinker, so that comprehensive information about the properties of the clinker can be detected as soon as possible.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst, wobei der aus einem Ofen fallende Klinker, in einem ersten Kühlerabschnitt und einem zweiten Kühlerabschnitt gekühlt und in einem zwischen den beiden Kühlerabschnitten angeordneten Brecher zerkleinert wird. In einem Bereich zwischen Brecher und zweitem Kühlerabschnitt wird eine Probe des Klinkers entnommen und analysiert, um Informationen über die Eigenschaften des Klinkers zu erfassen und auf vorangegangene Verfahrensabschnitte einzuwirken.According to the invention, this object is achieved by the features of claim 1, wherein the clinker falling from an oven is cooled in a first cooler section and a second cooler section and comminuted in a crusher arranged between the two cooler sections. In a region between the crusher and the second cooler section, a sample of the clinker is taken and analyzed in order to acquire information about the properties of the clinker and to act on previous process sections.

Gemäß einer bevorzugten Ausgestaltung ist die Einrichtung zur Entnahme einer Probe des Klinkers in einem Bereich angeordnet, wo die Temperatur des Klinkers zwischen 300° und 700° C, vorzugsweise zwischen 450° und 550° C beträgt.According to a preferred embodiment, the device for taking a sample of the clinker is arranged in a region where the temperature of the clinker is between 300 ° and 700 ° C, preferably between 450 ° and 550 ° C.

Durch den Ort der Probennahme zwischen dem ersten und zweiten Kühlerabschnitt ist es zudem möglich, eine Probe mit einem repräsentativen Kornspektrum zu nehmen. Bei einer im Stand der Technik bekannten Ausführung fällt die Probe in einem Mittelbereich des Kühlers durch ein Loch in der Rostplatte nach unten.The location of the sampling between the first and second cooler section also makes it possible to take a sample with a representative grain spectrum. In an embodiment known in the art, the sample falls down a hole in the grate plate in a central region of the radiator.

Vorzugsweise ist die Einrichtung zur Entnahme einer Probe des Klinkers in einem Bereich zwischen Brecher und zweitem Kühlerabschnitt angeordnet ist.Preferably, the device for taking a sample of the clinker is arranged in a region between the crusher and the second cooler section.

Weitere Ausgestaltungen der Erfindung werden anhand der Beschreibung eines Ausführungsbeispieles und der Zeichnung näher erläutert.Further embodiments of the invention will be explained in more detail with reference to the description of an embodiment and the drawing.

Die Zeichnung zeigt eine schematische Querschnittsdarstellung des Kühlers im Bereich zwischen dem ersten und zweiten Kühlerabschnitt.The drawing shows a schematic cross-sectional view of the radiator in the region between the first and second radiator section.

Der dargestellte Kühler besteht im Wesentlichen aus einem ersten Kühlerabschnitt 1, einem zweiten Kühlerabschnitt 2 sowie einem dazwischen angeordneten Brecher 3. Der zweite Kühlerabschnitt 2 ist tiefer als der erste Kühlerabschnitt 1 angeordnet, so dass das Material vom ersten Kühlerabschnitt 1 in den Brecher 3 gelangt und der zweite Kühlerabschnitt 2 unterhalb des Brechers angeordnet werden kann. Das zerkleinerte Material fällt dann vom Brecher 3 auf den zweiten Kühlerabschnitt 2.The cooler shown essentially consists of a first radiator section 1, a second radiator section 2 and a crusher 3 arranged therebetween. The second radiator section 2 is arranged lower than the first radiator section 1, so that the material passes from the first radiator section 1 into the crusher 3 and the second radiator section 2 can be arranged below the crusher. The crushed material then falls from the crusher 3 to the second radiator section 2.

In dem dargestellten Ausführungsbeispiel ist der Kühler mit einem feststehenden Belüftungsboden ausgebildet, wobei das Kühlgut mit geeigneten hin und her beweglichen Förderelementen über den Belüftungsboden bewegt wird. Im Rahmen der Erfindung wäre es jedoch auch möglich, den Kühler als so genannten Schubrostkühler mit abwechselnd feststehenden und hin und her beweglichen Rostplattenreihen auszuführen. Zur Kühlung des Gutes wird der Kühler in an sich bekannter Art und Weise von unten nach oben mit Kühlluft durchströmt.In the illustrated embodiment, the radiator is formed with a fixed ventilation floor, wherein the refrigerated goods is moved with suitable reciprocating conveying elements on the ventilation floor. In the context of the invention, however, it would also be possible, the cooler as a so-called grate cooler with alternately fixed and reciprocating Grate plate rows perform. For cooling the goods, the cooler is flowed through in a conventional manner from bottom to top with cooling air.

Weiterhin ist unterhalb des Brechers 3 eine Einrichtung 4 zur Entnahme einer Probe des Klinkers vorgesehen. Diese Einrichtung 4 weist einen geeigneten Probenehmer 4a auf, der in gewünschten Abständen Proben des nach unten fallenden zerkleinerten Klinkermaterials nimmt. Die Probe wird dann in einem Trichter 4b abgeladen und wird von dort in geeigneter Weise einer nicht näher dargestellten Analyseeinrichtung zugeführt. Die Analyse kann beispielsweise nach einem Röntgenfluoressenzverfahren und/oder nach einem Verfahren der Röntgendiffraktometrie erfolgen.Furthermore, a device 4 for taking a sample of the clinker is provided below the crusher 3. This device 4 has a suitable sampler 4a, which takes samples of the falling down crushed clinker material at desired intervals. The sample is then unloaded in a hopper 4b and is fed from there in a suitable manner to an analysis device, not shown. The analysis can be carried out, for example, according to an X-ray fluoride essence method and / or by a method of X-ray diffractometry.

Der Klinker fällt üblicherweise mit Temperaturen von etwa 1.400° C aus dem Ofen auf den ersten Kühlerabschnitt 1. Dort wird der Klinker in Richtung des Pfeils 5 transportiert und mit Kühlluft beaufschlagt. Am Ende des ersten Abschnittes gelangt der Klinker gemäß Pfeil 6 in den Brecher 3, wo eine Zerkleinerung des Klinkers erfolgt.The clinker usually falls with temperatures of about 1,400 ° C from the oven to the first radiator section 1. There, the clinker is transported in the direction of arrow 5 and charged with cooling air. At the end of the first section, the clinker passes in accordance with arrow 6 in the crusher 3, where a crushing of the clinker takes place.

Die Probennahme erfolgt in dem Bereich zwischen Brecher 3 und zweiten Kühlerabschnitt 2, indem eine Probe des aus dem Brecher fallenden Klinkers genommen wird. Entsprechend dem Pfeil 7 gelangt der gebrochene Klinker zur weiteren Abkühlung auf den zweiten Kühlerabschnitt.Sampling takes place in the area between crusher 3 and second cooler section 2 by taking a sample of the clinker falling from the crusher. According to the arrow 7, the broken clinker passes to the second cooler section for further cooling.

Im Rahmen der Erfindung wäre es jedoch auch möglich, die Probenahme mit einem geeigneten Probenehmer zwischen Kühlerabschnitt 1 und Brecher 3 erfolgen zu lassen.In the context of the invention, however, it would also be possible to take the sampling with a suitable sampler between radiator section 1 and crusher 3.

Der erste Kühlerabschnitt ist in seiner Länge so bemessen, und wird mit Kühlluft derart beaufschlagt, dass der Klinker im Bereich seiner Probennahme eine Temperatur zwischen 300° und 700° C, vorzugsweise zwischen 450° und 550° C aufweist, wobei man zweckmäßigerweise die Probennahme zeitlich möglichst früh vorsieht, um auf die vorangegangenen Verfahrensabschnitte frühzeitig einwirken zu können.The first cooler section is dimensioned in its length, and is supplied with cooling air such that the clinker in the region of its sampling has a temperature between 300 ° and 700 ° C, preferably between 450 ° and 550 ° C, wherein expediently the sampling time as early as possible provides for early intervention in the preceding stages of the procedure.

Da die Bildung der Klinkermineralien erst nach Unterschreiten von etwa 720°C abgeschlossen ist, sollte die Temperatur des Klinkers bei der Probenahme nicht deutlich über 650°C liegen.Since the formation of the clinker minerals is completed only after falling below about 720 ° C, the temperature of the clinker should not be significantly above 650 ° C during sampling.

Das Vorsehen eines Brechers 3 zwischen den beiden Kühlerabschnitten ermöglicht zum einen eine Probennahme mit einem repräsentativen Kornspektrum und zum anderen eine möglichst schnelle Analyse des Klinkers.The provision of a crusher 3 between the two cooler sections allows on the one hand a sampling with a representative grain spectrum and on the other hand the fastest possible analysis of the clinker.
