Description

Vorrichtung und Verfahren zur horizontalen Herstellung von Kohlestampfkuchen Apparatus and method for the horizontal production of coal cake
[0001] Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur horizontalen Herstel¬ lung eines Kohlepresskuchens zum Zwecke der Verkokung des Kohlekuchens in der Ofen¬ kammer eines Koksofens, wobei stationäre Presswerkzeuge eingesetzt werden, welche horizontal und mit einer eng begrenzten Hublänge arbeiten.The invention relates to a device and a method for the horizontal production of a coal press cake for the purpose of coking the coal cake in the Ofen¬ chamber of a coke oven, wherein stationary pressing tools are used, which operate horizontally and with a narrow stroke length.
[0002] Im Stand der Technik sind Vorrichtungen und Verfahren zum Stampfen von Kohle¬ kuchen seit langem bekannt, hierzu seien beispielhaft die DE 557 178 und DE 31 45 344 genannt. Stand der Technik ist es, die Kohlestampfkuchen derart herzustellen, dass dieser senkrecht nach oben bis zur vollen Höhe wächst.In the prior art devices and methods for pounding Kohle¬ cake have long been known, this example, the DE 557 178 and DE 31 45 344 called. The state of the art is to produce the coal cake such that it grows vertically up to full height.
[0003] DE 198 07 484 beschreibt hierzu ein Stampf verfahren zur. Dazu werden Stampfer- Stangen oberhalb einer losen Kohleschüttung mittels Linearmotoren angehoben und auf die Schüttung fallen gelassen. Ein ähnliches Verfahren wird auch in DE 35 33 071 oder DE 39 10 214 beschrieben. Diese Stampfvorrichtung muss folglich so aufgebaut sein, dass die Stangen geeignet sind, einen noch sehr flachen Kohlestampfkuchen genauso wie eine bereits vollständig gefüllte Presskammer versus fast fertigen Stampfkuchen gleichermaßen intensiv und gleichmäßig zu stampfen.For this purpose, DE 198 07 484 describes a tamping method for. For this purpose, rammer rods are raised above a loose bed of coal by means of linear motors and dropped onto the bed. A similar process is also described in DE 35 33 071 or DE 39 10 214. This stamper must therefore be constructed so that the bars are suitable to stomp an even very flat coal cake as well as an already completely filled press chamber against almost finished tamping cake equally intense and evenly.
[0004] Üblicher Weise sind Stampfkuchen und somit auch die Presskammern, in welchen diese hergestellt werden, in technischen Verkokungsanlagen 4m bis 7m hoch, was den Nachteil hat, dass für die Stampfstangen ein entsprechender zusätzlicher Raum oberhalb der Presskammern vorgesehen werden muss. Weiterhin müssen die Befüllvorrichtungen oberhalb dieser Presskammern angeordnet sein und die gesamte Kohleschüttung auf ein Niveau oberhalb der Presskammern gebracht werden, bevor es in die Presskammern ein¬ gefüllt werden kann.Conventionally, stamping cake and thus the pressing chambers in which they are produced in technical coking plants 4m to 7m high, which has the disadvantage that for the ramming rods a corresponding additional space above the pressing chambers must be provided. Furthermore, the filling devices must be arranged above these press chambers and the entire coal bed must be brought to a level above the press chambers before it can be filled into the press chambers.
[0005] Weiterhin ist im Stand der Technik bekannt, dass die Stampfstangen und vor allem die Füße der Stampfstangen den Eintrag der Schüttkohle im Wege sind. Hierzu wird in DE 31 45 344 vorgeschlagen, die Füße der Stampfstangen derart auszugestalten, dass die Stampfstangenfüße klappbar gestaltet sind, so dass sie der Kohle beim Einfüllen den freien Querschnitt weniger verschließen. Ein Nachteil dabei ist, dass die mechanisch hochbelas¬ teten Stampfstangenfüße mit beweglichen Elementen versehen werden, die schadensan¬ fälliger sind als eine starre Vorrichtung und gewartet werden müssen. In dieser Schrift wird die Höhe der Stampfkuchen mit 4m bis 6m angegeben.Furthermore, it is known in the art that the ramming rods and especially the feet of the ramming rods are the entry of the bulk coal in the way. For this purpose, it is proposed in DE 31 45 344 to design the feet of the ramming rods such that the ramming rod feet are designed to be foldable, so that they close the coal when filling the free cross section less. A disadvantage here is that the mechanically highly loaded rammer pole feet are provided with movable elements which are more susceptible to damage than a rigid device and must be maintained. In this document, the height of the rammed cake is given with 4m to 6m.
[0006] Zur Herstellung von niedrigen also flach liegenden Kohlestampfkuchen, wie sie übli¬ cher Weise in den sogenannten "non-recovery-coke ovens" eingesetzt werden schlägt DE 198 03 455 vor, den Kuchen in der bekannten stehenden Pressform zu stampfen und diese Pressform als Teil einer Kippvorrichtung auszugestalten, um den Presskuchen nach der Herstellung in die Horizontale bringen zu können. Diese Vorrichtung ist technisch sehr aufwendig.[0006] For the production of low-lying coal cake cakes, as they are usually used in the so-called "non-recovery coke ovens", DE 198 03 455 proposes to stamp the cake in the known stationary mold and this press mold as part of a tilting device to the press cake after the production in the horizontal to bring. This device is technically very complicated.
[0007] US 3,912,091 offenbart eine Vorrichtung, in welcher ein liegender Stampf kuchen hergestellt wird. Hierbei wird während des Füllvorgangs die Kohle in der Kammer senkrecht von oben planiert und gleichzeitig auch in der Kammer verdichtet. Der Betrieb der aufwen¬ digen Förder- und Verdichtungseinrichtung in der heißen Ofenkammer ist technisch sehr anspruchsvoll, da eine aufwändige Wasserkühlung für den Förderer erforderlich ist. Insbe¬ sondere sind die Erschütterungen durch die Verdichtungseinrichtung kritisch zu betrachten, da hierdurch Beschädigungen am Mauerwerk hervorgerufen werden können. Weiterhin ist nachteilig, dass die Planierwerkzeuge mobil aus geführt werden müssen, damit sie über dem Stampfkuchen bewegt werden können.US 3,912,091 discloses a device in which a horizontal stamping cake is produced. During the filling process, the coal in the chamber is leveled vertically from above and at the same time compacted in the chamber. The operation of the aufwen¬ ended conveying and compressing device in the hot oven chamber is technically very demanding, since a complex water cooling is required for the conveyor. In particular, the vibrations caused by the compacting device are to be considered critically, since this can cause damage to the masonry. Another disadvantage is that the grading tools must be performed from mobile so that they can be moved over the stamping cake.
[0008] In DE 195 45 736 wird ebenfalls die Herstellung eines liegenden Kohlepresskuchens offenbart, wobei die Kohleschüttung außerhalb des Ofens in einen sogenannten Setzkasten gefüllt wird und anschließend verdichtet wird. Die Abmessungen des fertigen Kohlekuchens werden in DE 195 45 736 mit vorzugsweise 0,6m hoch, 3-5m breit und 10-2Om lang ange¬ geben. Ein Verfahren zur Verdichtung dieses liegenden Kohlekuchens wird in der Schrift nicht ausgeführt.DE 195 45 736 also discloses the production of a horizontal Kohlepresskuchens, wherein the coal bed outside the furnace is filled into a so-called setting box and is then compressed. The dimensions of the finished coal cake are given in DE 195 45 736 with preferably 0.6 m high, 3-5 m wide and 10-2Om long ange¬. A method for compacting this horizontal coal cake is not carried out in the document.
[0009] Aufgabe der Erfindung ist es somit, den Mangel im Stand der Technik zu beheben und eine Kohlepressvorrichtung und ein Verfahren bereitzustellen, welches durch eine kompaktere Bauform wirtschaftlicher arbeitet und die selben oder bessere Presseigen¬ schaften hat, wie bekannte Stampfvorrichtung und Stampfverfahren.The object of the invention is therefore to remedy the deficiency in the prior art and to provide a Kohlepressvorrichtung and a method which works more economically by a more compact design and the same or better Presseigen¬ has properties, such as known tamping and stamping process.
[0010] Die Erfindung löst die Aufgabe dadurch, dass zur Herstellung eines verdichteten Kohlekuchens aus einem schüttfähigen Kohlenmaterial zum Einsatz in einem Verkokungs¬ ofen eine hydraulische Pressvorrichtung eingesetzt wird, welche mindestens aus einem Hydraulikstempel, einer Pressform, einer im Boden der Pressform eingelegten und ent¬ nehmbaren Kuchenträgerplatte und einer über der Pressform angeordneten Schüttrinne besteht, die weiterhin , dadurch gekennzeichnet, dass die Pressform aus einem Wagen oder Schlitten gebildet wird, der Wandungen, einen Boden und eine Anschlagwand um- fasst, oberhalb welchem quer zu dessen Fahrtrichtung die Schüttrinne angeordnet ist, die Hydraulikzylinder, welche stationär befestigt sind und ein Zylinderkopfstück in horizontaler Richtung bewegen, beim Vortrieb das aus der Schüttrinne kommende Kohlematerial mittels des Zylinderkopfstücks quer zur Schüttrinne und unter dieser hindurch gegen die An¬ schlagwand und unter einer ebenen Presskuchenabdeckung hindurch pressen, wobei der Wagen mit einer der Vortriebsrichtung der Hydraulikzylinder entgegengesetzten Kraft ge- bremst wird, und die Presskuchenabdeckung, die sich direkt an die Schüttrinne anschließt, sowie das Zylinderkopfstück und die Schüttrinne parallel ausgerichtet sind.[0010] The invention achieves this object by using a hydraulic pressing device for producing a compacted coal cake from a free-flowing coal material for use in a coking furnace, which is composed of at least one hydraulic ram, one press mold, one inserted in the bottom of the press mold and ent ¬ acceptable Kuchenträgerplatte and arranged above the mold chute, which further, characterized in that the mold is formed of a carriage or carriage, the walls, a bottom and a stop wall encompasses above which arranged transversely to the direction of travel, the chute is, the hydraulic cylinder, which are fixed stationary and move a cylinder head piece in the horizontal direction, during propulsion coming from the chute coal material by means of the cylinder head piece transverse to the chute and under this against the An¬ stop wall and under a flat Pressk pressing the carriage cover, wherein the carriage has a force opposite the direction of advance of the hydraulic cylinders. is braked, and the press cake cover, which connects directly to the chute, and the cylinder head piece and the chute are aligned in parallel.
[0011] Eine vorteilhafte Ausführung besteht darin, dass das Zylinderkopfstück aus einer vertikalen Druckplatte und einer horizontalen Verschlussplatte gebildet ist, wobei das Zylin¬ derkopfstück den Auslass der Schüttrinne in der Ruheposition, welche die ersten Endpositi¬ on darstellt, nicht verengt und beim Vortrieb die Verschlussplatte des Zylinderkopfes den Auslass der Schüttrinne fortschreitend verengt und bei maximalem Hub, der zweiten End¬ position, den Auslass der Schüttrinne vollständig verschließt.An advantageous embodiment is that the cylinder head piece is formed from a vertical pressure plate and a horizontal closure plate, the Zylin derkopfstück the outlet of the chute in the rest position, which is the first Endpositi¬ on, not narrowed and the propulsion Closing plate of the cylinder head progressively narrows the outlet of the chute and, at maximum stroke, the second End¬ position, the outlet of the chute completely closes.
[0012] In einer weiteren vorteilhaften Ausgestaltung der erfinderischen Vorrichtung, ist das Zylinderkopfstück quer zur Vortriebsrichtung in mindestens zwei Teilstücke unterteilt ist.In a further advantageous embodiment of the inventive device, the cylinder head piece is divided transversely to the direction of advance into at least two sections.
[0013] Vorteilhaft ist ebenfalls eine Variante der erfinderischen Vorrichtung, in welcher die Presskuchenabdeckung die Pressform in Vortriebsrichtung des Kohlekuchens nur teilweise überdeckt, in der Höhe verstellt werden kann und sie insbesondere zur Kohlekuchenent¬ nahme angehoben werden kann. Dabei ist es vorteilhaft, wenn die Presskuchenabdeckung beziehungsweise deren Aufhängung derart gestaltet ist, dass der Auflagedruck auf den Kohlekuchen veränderbar ist.Also advantageous is a variant of the inventive device in which the press cake cover the mold in the direction of advancement of the coal cake only partially covered, can be adjusted in height and they can be raised in particular for Kohlekuchenent¬ exception. It is advantageous if the press cake cover or its suspension is designed such that the contact pressure on the coal cake is changeable.
[0014] In einer weiter optimierten Ausführungsform ist die Presskuchenabdeckplatte in Vortriebsrichtung der Hydraulikzylinder segmentiert, so dass der Auflagedruck der einzel¬ nen Segmente voneinander unabhängig eingestellt werden kann.In a further optimized embodiment, the press cake cover plate is segmented in the advancing direction of the hydraulic cylinders, so that the contact pressure of the individual segments can be adjusted independently of one another.
[0015] Ein optimierte Variante der Vorrichtung sieht vor, die Bremskraft der als Wagen oder Schlitten geformten Pressform so zu gestalten, dass diese veränderbar ist. Somit ist es möglich, über die horizontal und vertikal veränderbare Presskraft, auf unterschiedliche Kohlequalitäten der Schüttung zu reagieren und eine optimale Formgebung des Kohleku¬ chens sicherzustellen.An optimized variant of the device provides to make the braking force of the mold formed as a carriage or slide mold so that it is changeable. Thus, it is possible, via the horizontally and vertically variable pressing force, to respond to different coal qualities of the bed and to ensure optimum shaping of the coal hood.
[0016] Ideal ist es, wenn Hydraulikzylinder, Schüttrinne und Presskuchenabdeckplatte pa¬ rallel zur Schmalseite des Wagens angeordnet sind, so dass die Dimensionierung dieser Vorrichtungskomponenten möglichst klein ausgeführt werden können.[0016] It is ideal if hydraulic cylinders, chute and press cake cover plate are arranged parallel to the narrow side of the carriage, so that the dimensioning of these device components can be made as small as possible.
[0017] Weiterhin ist von der Erfindung eine Vorrichtung umfasst, welche als Pressform zur vorstehend beschriebenen Vorrichtung eine flache Wanne einsetzt. Dabei ist in der Wanne eine verschiebbare Anschlagswand angeordnet, oberhalb welcher und parallel zur An¬ schlagswand eine Schüttrinne angeordnet ist, die Hydraulikzylinder, welche stationär befes¬ tigt sind und ein Zylinderkopfstück in horizontaler Richtung bewegen, beim Vortrieb das aus der Schüttrinne kommende Kohlematerial mittels des Zylinderkopfstücks quer zur Schüttrinne und unter dieser hindurch gegen die Anschlagwand und unter einer ebenen Presskuchenabdeckung hindurch pressen, wobei die Anschlagswand mit einer der Vor¬ triebsrichtung der Hydraulikzylinder entgegengesetzten Kraft gebremst wird, und die Press¬ kuchenabdeckung, welche sich direkt an die Schüttrinne anschließt, sowie, das Zylinder¬ kopfstück und die Schüttrinne parallel ausgerichtet sind.Furthermore, the invention comprises a device which uses a flat pan as a mold for the device described above. In this case, a slidable abutment wall is arranged in the tub, above which and parallel to An¬ impact wall a chute is arranged, the hydraulic cylinder, which are stationary fastened and move a cylinder head piece in the horizontal direction, during propulsion coming from the chute coal material by means of Cylinder head piece across the chute and under this against the stop wall and under a flat Press the press cake cover, wherein the stop wall is braked with a force opposite the feed direction of the hydraulic cylinder, and the press cake cover, which adjoins directly to the chute, and the cylinder head piece and the chute are aligned in parallel.
