Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung, mit einem nach oben offenen Formkasten zur Aufnahme einer gemahlene Kohle umfassenden Schüttung und wenigstens einem auf die Schüttung in dem Formkasten einwirkenden Stoßelement zur Verdichtung und Verfestigung der Schüttung zu einem Block, und einen zur Auflage auf die Schüttung vorgesehenen, den Impuls des Stoßelements wenigstens teilweise auf die Schüttung übertragenden Stempelblock.The invention relates to a device for producing a coal cake for coking, comprising an upwardly open molding box for receiving a ground coal bulk and at least one acting on the bed in the mold box shock element for compacting and solidification of the bed to form a block, and a Pad provided on the bed, the momentum of the push element at least partially on the bed transmitting stamp block.

Aus der DE 10 2006 029 768 A1 ist eine Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung bekannt, welche Pressstempel zum statischen Zusammenpressen der Kohleschüttung umfasst, wobei die Pressdruck ausübenden Pressstempel gleichzeitig je durch einen Hammer beaufschlagbar sind, dessen Impuls über den Pressstempel auf das Schüttgut übertragen wird.From the DE 10 2006 029 768 A1 a device for producing a coal cake for coking is known, which comprises pressing ram for static compression of the coal bed, wherein the pressing pressure exerting punches are each acted upon by a hammer, whose pulse is transmitted to the bulk material via the press ram.

Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber letzterem Stand der Technik konstruktiv vereinfachte Vorrichtung der eingangs erwähnten Art, die auf Verdichtung der Kohleschüttung im wesentlichen nur durch Impulseinwirkung beruht und hinsichtlich Effizienz der Kohleverdichtung sowie des erreichten Verdichtungs- und Verfestigungsgrades deutlich verbessert ist, zu schaffen.The invention is based on the object, compared to the latter prior art constructively simplified device of the type mentioned above, which is based on compression of the coal bed substantially only by pulse action and in terms of efficiency of coal compaction and the achieved degree of compaction and solidification is significantly improved to create ,

Die diese Aufgabe lösende Vorrichtung nach der Erfindung ist gekennzeichnet dadurch, dass das Stoßelement und der Stempelblock Bestandteil einer Bearbeitungseinheit ins, die in ihrer Gesamtheit mit Hilfe einer Bewegungseinrichtung sowohl horizontal als vertikal verfahrbar ist und dass Einrichtungen zur beweglichen Ankopplung des Stempelblocks an die Bearbeitungseinheit vorgesehen sind.The device according to the invention that achieves this object is characterized in that the impact element and the stamp block are part of a machining unit which is horizontally and vertically movable in its entirety by means of a movement device and in which means for movably coupling the stamp block to the machining unit are provided ,

Erfindungsgemäß sind jeweils ein Stoßelement und jeweils ein Stempelblock Bestandteil einer Bearbeitungseinheit, die in ihrer Gesamtheit durch eine Bewegungseinrichtung sowohl horizontal als auch vertikal verfahrbar ist. Ferner sind erfindungsgemäß Einrichtungen, z.B. flexible Stränge, zur beweglichen Ankopplung des Stempelblocks an die genannte Bearbeitungseinheit vorgesehen, so dass der Stempelblock einerseits beweglich auf dem Schüttgut aufliegen kann, es aber andererseits möglich ist, die Bearbeitungseinheit einschließlich Stempelblock von der Schüttung abzuheben, um z.B. weitere Schüttungslagen in den Formkasten einzubringen.According to the invention, one impact element and one stamp block in each case form part of a processing unit which, in its entirety, can be moved both horizontally and vertically by a movement device. Further are Inventive devices, eg flexible strands, provided for the movable coupling of the stamp block to said processing unit, so that the stamp block on the one hand movable on the bulk material can rest, but on the other hand it is possible to withdraw the processing unit including stamp block from the bed, for example, further bedding layers in to introduce the molding box.

Vorteilhaft kann der erfindungsgemäße Stempelblock ohne selbst eine mit der Aufschlaggeschwindigkeit des Stabelements vergleichbar hohe Geschwindigkeit zu erreichen, ggf. den gesamten Hammerimpuls übertragen. Infolge der gegenüber der Geschwindigkeit des Stoßelements verringerten Geschwindigkeit des Stempelblocks sind seitliche Materialverdrängungen beim Stoßvorgang, anders als würde das Stoßelement direkt auf der Schüttung aufschlagen, weitgehend vermieden, und es kommt zu einer auf die Stoßrichtung konzentrierten Verdichtung des Schüttguts. Auch werden die angrenzenden Seitenwände des Formkastens weniger belastet.Advantageously, the stamp block according to the invention without even achieve a speed comparable to the impact speed of the rod element, possibly transmit the entire hammer pulse. As a result of the speed of the stamping block, which is reduced compared to the speed of the pushing element, lateral material displacements during the impact process, in contrast to the impact element striking the bed, are largely avoided, and compacting of the bulk material is concentrated in the direction of impact. Also, the adjacent side walls of the mold box are less loaded.

Zweckmäßig übt das Stoßelement auf den Stempelblock einen geraden elastischen Stoß aus, so dass Kippbewegungen des Stempelblocks in Bezug auf die Stoßrichtung vermieden sind und sich das Schüttgut unter dem Stempelblock säulenartig in die Tiefe hinein verdichtet.Suitably, the impact element exerts a straight elastic impact on the stamp block, so that tilting movements of the stamp block with respect to the impact direction are avoided and the bulk material under the stamp block compacts into the depth in the manner of a column.

Vorzugsweise ist die der Schüttung zugewandte Stempelfläche des Stempelblocks größer als die dem Stempelblock zugewandte Aufschlagfläche des Stoßelements oder höchstens gleich dieser Fläche.Preferably, the filling facing the stamp surface of the die block is greater than the die block facing the impact surface of the shock element or at most equal to this surface.

Die Masse des Stoßelements, des Stempelblocks und die Stempelfläche des Stempelblocks können derart aufeinander abgestimmt sein, dass das Stoßelement beim Stoß seinen gesamten Impuls verliert oder an dem Stempelblock zurückgeworfen wird. In letzterem Fall wird nur ein Teil der Bewegungsenergie des Stoßelements übertragen, was ggf. durch eine Erhöhung der Schlagfrequenz ausgleichbar ist, wobei das Zurückprallen des Stoßelements einer Erhöhung der Schlagfrequenz entgegenkommt.The mass of the impact element, the stamp block and the stamp surface of the stamp block can be matched to one another such that the impact element loses its entire momentum during impact or is reflected back on the stamp block. In the latter case, only a part of the kinetic energy of the shock element is transmitted, which can be compensated if necessary by an increase of the impact frequency, wherein the rebounding of the impact element accommodates an increase in the beat frequency.

Die Masse des Stoßelements kann geringer oder größer als die Masse des Stempelblocks sein.The mass of the impact element may be less than or greater than the mass of the stamp block.

Der Stempelblock erstreckt sich ggf. über die gesamte Breite des Stempelkastens. In einer nicht erfindungsgemäßen Ausführungsform könnte er sich zusätzlich über dessen gesamte Länge erstrecken. In letzterem Fall deckt er die gesamte Oberfläche der Schüttung ab und es sind ggf. mehrere, an unterschiedlichen Stellen des Stempelblocks aufschlagende Stoßelemente vorgesehen, oder es ist wenigstens ein Stoßelement in Längsrichtung des Stempelblocks verfahrbar.The stamp block optionally extends over the entire width of the stamp box. In a non-inventive embodiment, it could additionally extend over its entire length. In the latter case it covers the entire surface of the bed and it may be provided several, impacting at different locations of the die block impact elements, or it is at least one impact element in the longitudinal direction of the die block movable.

In weiterer Ausgestaltung der Erfindung weist die der Schüttung zugewandte Stempelfläche des Stempelblocks eine die Verdichtung der Schüttung auf einen Bereich um die Stoßachse konzentrierende Formung auf.In a further refinement of the invention, the stamp surface of the stamp block facing the bed has a shaping concentrating the compaction of the bed on a region around the joint axis.

Zweckmäßig ist die Stempelfläche derart geformt, dass das Schüttgutmaterial beim Stoß möglichst nicht senkrecht zur Stoßrichtung ausweichen kann. Die Stempelfläche kann z.B. konkav sein oder eine an eine solche Stempelfläche angenäherte Form aufweisen.Suitably, the stamp surface is shaped so that the bulk material when possible can not dodge perpendicular to the direction of impact. The stamp surface may e.g. be concave or have a shape approximated to such a stamp surface.

In weiterer vorteilhafter Ausgestaltung der Erfindung sind die Aufschlaggeschwindigkeit, die Schlagfrequenz und die Masse des Stoßelements veränderbar, so dass eine Anpassung an unterschiedliche Schüttguteigenschaften erfolgen oder sonstigen Veränderungen der Bedingungen für die Verdichtung, z.B. mit steigender Schütthöhe, Rechnung getragen werden kann.In a further advantageous embodiment of the invention, the impact speed, the impact frequency and the mass of the impact element are variable, so that adaptation to different bulk material properties or other changes in the conditions for the compression, e.g. with increasing dumping height, can be accommodated.

In einer bevorzugten Ausführungsform der Erfindung weisen der Stempelblock und das Stoßelement Einrichtungen zur Zentrierung des Stoßelements auf dem Stempelblock beim Stoß auf.In a preferred embodiment of the invention, the die block and the push element have means for centering the push element on the die block during impact.

Die erfindungsgemäße Vorrichtung kann eine Regelung aufweisen, die einen die Verdichtungswirkung erfassenden Sensor und eine das Sensorsignal verarbeitende, die Impulsübertragung durch das Stoßelement unter Einregelung einer gewünschten Verdichtungswirkung ändernde Steuerung umfasst.The device according to the invention can have a control which comprises a sensor which detects the compression effect and a control which processes the sensor signal and which changes the momentum transmission by the impact element under the control of a desired compression effect.

Zweckmäßig erfasst der Sensor eine für die Verdichtungswirkung maßgebende kinematische Größe des Stempelblocks, z.B. den durch die Impulsübertragung erreichten Vorschub des Stempelblocks oder dessen maximale Bremsbeschleunigung.The sensor expediently detects a kinematic variable of the stamp block, which is decisive for the compaction effect, e.g. the achieved by the impulse transmission feed of the stamp block or its maximum braking acceleration.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen und der beiliegenden, sich auf diese Ausführungsbeispiele beziehenden Zeichnungen weiter erläutert. Es zeigen:

The invention will be explained below with reference to embodiments and the accompanying, relating to these embodiments drawings. Show it:

Eine in Fig. 1 schematisch in einem Längsschnitt wiedergegebene Vorrichtung zur Herstellung eines Kohlekuchens umfasst einen nach oben offenen Formkasten 1 zur Aufnahme einer lagenweise oder einmalig eingebrachten, gemahlene Kohle und ggf. ein Bindemittel aufweisenden Schüttung 2. Die Innenmaße des Formkastens betragen in dem gezeigten Beispiel 7 x 0,5 x 17 m, wobei sich das Maß 7m auf die Höhe bezieht.An in Fig. 1 schematically in a longitudinal section reproduced device for producing a coal cake comprises an upwardly open molding box 1 for receiving a layered or one-time, ground coal and possibly a binder having bed 2. The inner dimensions of the mold box in the example shown 7 x 0.5 x 17 m, whereby the measure 7m refers to the height.

Eine über der Schüttung 7 angeordnete Bearbeitungseinheit 3 umfasst einen Fallhammer 4 sowie einen zum Auflegen auf die Schüttung 2 vorgesehenen Stempelblock 5.A processing unit 3 arranged above the bed 7 comprises a drop hammer 4 and a stamp block 5 provided for placement on the bed 2.

Durch eine in Fig. 1 schematisch dargestellte Bewegungseinrichtung 6 lässt sich die Bearbeitungseinheit 3 sowohl vertikal in den Formkasten 1 hinein und aus dem Formkasten heraus als auch horizontal in Längsrichtung der Öffnung 7 des Formkasten 1 bewegen. Relativ zu der Bearbeitungseinheit 3 in vertikaler Richtung gesondert bewegbar ist der Fallhammer 4. Einrichtungen zur Halterung und Führung des Stempelblocks 5 an der Bearbeitungseinheit 3 sowie Antriebsmittel für den Fallhammer 4 sind nicht gezeigt.By a in Fig. 1 schematically shown moving device 6, the processing unit 3 can both vertically into the molding box 1 and out of the molding box out and move horizontally in the longitudinal direction of the opening 7 of the molding box 1. The drop hammer 4 is movable separately relative to the processing unit 3 in the vertical direction. Devices for holding and guiding the punch block 5 on the processing unit 3 as well as drive means for the drop hammer 4 are not shown.

Im Unterschied zu dem dargestellten Beispiel könnten anstelle einer einzigen Bearbeitungseinheit 3 mehrere Bearbeitungseinheiten vorgesehen sein, ggf. in solcher Anzahl, dass die gesamte Oberfläche der Schüttung durch die Stempelblöcke dieser Bearbeitungseinheiten vollständig abgedeckt ist (nicht erfindungsgemäß).In contrast to the illustrated example, instead of a single processing unit 3, a plurality of processing units could be provided, possibly in such a number that the entire surface of the bed is completely covered by the stamping blocks of these processing units (not according to the invention).

Wie Fig. 2 erkennen lässt, erstreckt sich der Stempelblock 5 über die gesamte Breite der Öffnung 7, d.h. über die gesamte horizontale Breite des Formkastens 1.As Fig. 2 can recognize the punch block 5 extends over the entire width of the opening 7, that is, over the entire horizontal width of the molding box. 1

Zur Herstellung eines Kohlekuchens wird der Formkasten 1 in dem gezeigten Beispiel lagenweise mit der Schüttung 2 gemahlener Steinkohle oder einer Kohleteilchen und ein Bindemittel umfassenden Schüttung befüllt und die Schüttung 2 nach jeder Befüllung mit Hilfe der Bearbeitungseinheit 3 verdichtet und schließlich zu einem sogenannten Kohlekuchen, d.h. einem kompaktierten Formblock, verfestigt. Entsprechend ist in der Anfangsphase der Kohlekuchenherstellung die Bearbeitungseinheit 3 durch die Bewegungseinrichtung 6 weit in die Tiefe des Formkastens 1 hinein zu versenken. Die Bewegungseinrichtung 6 sorgt ferner für horizontale Verschiebungen der Bearbeitungseinheit 3 in Positionen über Verdichtungsabschnitten 8. Die Anzahl der Verdichtungsabschnitte 8 ist etwa gleich dem Quotienten aus der horizontalen Länge des Formkastens 1 und der Länge des Stempelblocks 5 in Längsrichtung des Formkastens 1.To produce a coal cake, the molding box 1 is filled in layers in the example shown with the bed 2 milled coal or coal particles and a binder comprising bulk and compacted the bed 2 after each filling by means of the processing unit 3 and finally into a so-called coal cake, ie a compacted molding block, solidified. Accordingly, in the initial phase of the production of coal cake, the processing unit 3 is to be sunk far into the depth of the molding box 1 by the movement device 6. The movement device 6 further provides for horizontal displacements of the processing unit 3 in positions above compression sections 8. The number of compression sections 8 is approximately equal to the quotient of the horizontal length of the molding box 1 and the length of the stamp block 5 in the longitudinal direction of the molding box 1.

Vor Aktivierung des Fallhammers 4 wird der Stempelblock 5 in dem mit Hilfe der Bewegungseinrichtung 6 angefahrenen Verdichtungsabschnitt 8 durch die Bearbeitungseinheit 3 auf der Oberfläche der Schüttung 2 abgelegt, so dass er mit seiner der Schüttung zugewandten Stempelfläche 9 gegen das Kohlematerial anliegt.Before activation of the drop hammer 4, the stamping block 5 is deposited in the approached by means of the moving device 6 compression section 8 by the processing unit 3 on the surface of the bed 2, so that it rests with its the bulkhead facing punch surface 9 against the carbon material.

In diesem Zustand trifft der Fallhammer 4 jeweils mit einer vorbestimmten Geschwindigkeit zentral auf den Stempelblock 5 auf, wobei er auf den Stempelblock einen im Wesentlichen geraden, elastischen Stoß ausübt. Die Masse des Fallhammers 4, die Masse des Stempelblocks 5 und die Stempelfläche 9 des Stempelblocks 5 sind in dem gezeigten Beispiel so bemessen, dass der Fallhammer 4 am Ende des Stoßvorgangs zur Ruhe kommt und somit seinen gesamten Impuls über den Stempelblock 5 auf die Schüttung 2 überträgt. Alternativ könnte nur eine teilweise Übertragung der Hammerenergie erfolgen, so dass das Stoßelement mit einer gegenüber der Geschwindigkeit vor dem Stoß verringerten Geschwindigkeit zurückprallt.In this state, the drop hammer 4 hits centrally at a predetermined speed on the die block 5, wherein it exerts on the die block a substantially straight, elastic shock. The mass of the drop hammer 4, the mass of the die block 5 and the die surface 9 of the die block 5 are dimensioned in the example shown so that the drop hammer 4 comes to rest at the end of the shock process and thus its entire impulse on the stamp block 5 on the bed. 2 transfers. Alternatively, only a partial transfer of the hammer energy could occur, so that the shock element rebounds at a speed reduced from the impact speed.

Ein in Fig. 3 gezeigter Stempelblock 5a weist abweichend von dem vorangehend beschriebenen Stempelblock 5 eine leicht konkave Stempelfläche 9a auf, die dafür sorgt, dass sich die Schüttgutverdichtung auf einen durch Strichlinien 10 und 11 angedeuteten Bereich um die Stoßachse 11 herum konzentriert. Durch diese Maßnahme lässt es sich weitgehend vermeiden, dass Material seitlich in benachbarte, bereits behandelte Verdichtungsabschnitte 8a hinein abfließt und es unter Anhebung der verdichteten Oberfläche wieder zu einer Reduzierung des Dichtegrades in den benachbarten Verdichtungsabschnitten 8a kommt.An in Fig. 3 In contrast to the above-described stamp block 5, shown stamp block 5a has a slightly concave stamp face 9a, which ensures that the bulk material compaction concentrates on a region indicated by broken lines 10 and 11 around the impact axis 11. By this measure, it can largely be avoided that material flows laterally into adjacent, already treated compression sections 8a and, with an increase in the compacted surface, again leads to a reduction in the degree of density in the adjacent compression sections 8a.

Als weiteren Unterschied gegenüber dem Stempelblock 5 weist der Stempelblock 5a auf seiner dem Fallhammer 3a zugewandten Seite eine konische Vertiefung 13 auf, welcher ein entsprechender Endkonus 14 eines Fallhammers 4a gegenüberliegt. Die Vertiefung 13 und der Konus 14 bilden eine den Fallhammer 4a beim Stoß zentrierende Führung, die einen geraden Stoß ohne Verkantung des Stempelblocks 5a sichert.As a further difference with respect to the stamp block 5, the stamp block 5a has a conical recess 13 on its side facing the drop hammer 3a, which confronts a corresponding end cone 14 of a drop hammer 4a. The recess 13 and the cone 14 form a case hammer 4a at Butt centering guide which ensures a straight joint without jamming of the punch block 5a.
