Description

Beschreibung:  Description:
„Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung" "Apparatus for producing a coal cake for coking"
Die Erfindung betrifft eine Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung, mit einem nach oben offenen Formkasten zur Aufnahme einer gemahlene Kohle mit oder ohne Bindemittel umfassenden Schüttung und wenigstens einem auf die Schüttung in dem Formkasten einwirkenden Stoßelement zur Verdichtung und Verfestigung der Schüttung zu einem Block. The invention relates to a device for producing a coal cake for coking, with an upwardly open molding box for receiving a ground coal with or without binder comprehensive bed 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 ,
Aus der DE 10 2006 029 768 AI ist eine Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung bekannt, welche Pressstempel zum statischen Zusam- menpressen 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 DE 10 2006 029 768 AI a device for producing a coal cake for coking is known, which press punches for static compression of the co m comprises, wherein the pressing pressure exerting punches are each acted upon by a hammer, whose impulse on the ram on the bulk material is transferred.
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 Ver- dichtungs- und Verfestigungsgrades deutlich verbessert ist, zu schaffen. Die diese Aufgabe lösende Vorrichtung nach der Erfindung ist gekennzeichnet durch einen zur Auflage auf die Schüttung vorgesehenen Stempelblock, der den Impuls des Stabelements wenigstens teilweise auf die Schüttung überträgt. The invention is based on the object, compared to the latter prior art constructively simplified device of the type mentioned, which is based on compression of the coal bed substantially only by pulse action and in terms of efficiency of coal compression and the achieved compression and solidification degree is significantly improved, to accomplish. The problem solving device according to the invention is characterized by a provided for resting on the bed block block, which at least partially transmits the pulse of the rod element to the bed.
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 Stempel blocks 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 reduced compared to the speed of the shock element speed of the punch block lateral material displacements during the impact process, unlike would strike the shock element directly on the bed, largely avoided, and there is a concentrated in the direction of impact compression of the bulk material. Also, the adjacent side walls of the mold box are less loaded.
Zweckmäßig übt das Stoßelement auf den Stempelblock einen geraden, vorzugsweise 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. Expediently, the impact element exerts a straight, preferably 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.
Vorzugsweise ist die der Schüttung zugewandte Stempelfläche des Stempel blocks größer als die dem Stempelblock zugewandte Aufschlagfläche des Stoßelements oder höchstens gleich dieser Fläche. Die Masse des Stoßelements, des Stempelblocks und die Stempelfläche desPreferably, the bulk of the facing punch surface of the punch block is greater than the punch block facing impact surface of the shock element or at most equal to this surface. The mass of the impact element, the stamp block and the stamp surface of the
Stempelblocks können derart aufeinander abgestimmt sein, dass das Stoßelement beim Stoß seinen gesamten Impuls verliert oder an dem Stempel block zurückgeworfen wird. In letzterem Fall wird nur ein Teil der Bewegungsenergie des Stoßelements übertragen, was ggf. durch eine Erhöhung der Schlagfrequenz aus- gleichbar ist, wobei das Zurückprallen des Stoßelements einer Erhöhung der Schlagfrequenz entgegenkommt. Stamp block can be coordinated so that the shock element loses its entire momentum when shock or block is thrown back on the stamp. 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, the rebounding of the impact element counteracting an increase of 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. Er könnte 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 vor- gesehen, oder es ist wenigstens ein Stoßelement in Längsrichtung des Stempelblocks verfahrbar. The stamp block optionally extends over the entire width of the stamp box. He could also extend over its entire length. In the latter case, it covers the entire surface of the bed and, if appropriate, several impact elements striking at different locations of the stamp block are provided, or at least one impact element can be moved in the longitudinal direction of the stamp block.
Vorzugsweise sind jedoch jeweils ein Stoßelement und jeweils ein Stempelblock Bestandteil einer Bearbeitungseinheit, die in ihrer Gesamtheit durch eine Bewegungs- einrichtung sowohl horizontal als auch vertikal verfahrbar ist. Preferably, however, in each case one impact element and one stamp block in each case form part of a machining unit which, in its entirety, can be moved both horizontally and vertically by a movement device.
Zweckmäßig sind 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. Appropriately, facilities, such as flexible strands, provided for the movable coupling of the stamp block to said processing unit, so that the Stamp block on the one hand can rest on the bulk material movable, but it is possible, on the other hand, to lift the processing unit including stamp block from the bed, for example, to introduce more bedding layers in the mold box.
In weiterer Ausgestaltung der Erfindung weist die der Schüttung zugewandte Stempelfläche des Stempel blocks eine die Verdichtung der Schüttung auf einen Bereich um die Stoßachse konzentrierende Formung auf. 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. 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 embodiment of the invention, the filling facing the stamp surface of the punch blocks on a compaction of the bed on a region concentrating around the shock axis shaping. 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 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 In a preferred embodiment of the invention, the die block and the impact element have means for centering the impact element on the
Stempelblock beim Stoß auf. 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. 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. Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen und der beiliegenden, sich auf diese Ausführungsbeispiele beziehenden Zeichnungen weiter erläutert. Es zeigen: Hg. i ein Schema einer erfindungsgemäßen Vorrichtung in einer geschnittenen Seitenansicht, Stamp block on impact. The device according to the invention can have a control which comprises a sensor which detects the compacting action and a control which processes the sensor signal and which changes the momentum transmission by the impact element under the control of a desired compacting effect. The sensor expediently detects a kinematic variable of the stamp block which is decisive for the compaction effect, for example the advance of the stamp block achieved by the momentum transfer or its maximum deceleration. The invention will be explained below with reference to embodiments and the accompanying, relating to these embodiments drawings. Show it: Hg.

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. Eine über der Schüttung 7 angeordnete Bearbeitungseinheit 3 umfasst einen Fallhammer 4 sowie einen zum Auflegen auf die Schüttung 2 vorgesehenen Stempel- block 5. A device shown schematically in a longitudinal section in FIG. 1 for producing a coal cake comprises an upwardly open molding box 1 for receiving a layered or uniquely introduced ground coal and, if appropriate, a binder 2. The internal dimensions of the molding box are in the example shown 7 x 0.5 x 17 m, whereby the dimension 7m refers to the height. A processing unit 3 arranged above the bed 7 comprises a drop hammer 4 and a punch 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 means of a movement device 6 shown schematically in FIG. 1, the processing unit 3 can be moved both vertically into the molding box 1 and out of the molding box as well as 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 Stempel- blocke dieser Bearbeitungseinheiten vollständig abgedeckt ist. 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 stamp block of these processing units.
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 . Zur Herstellung eines Kohlekuchens wird der Formkasten 1 in dem gezeigtenAs can be seen from Fig. 2, the stamp block 5 extends over the entire width of the opening 7, i. over the entire horizontal width of the molding box 1. For producing a coal cake, the molding box 1 is shown in FIG
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 . 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. In diesem Zustand trifft der Fallhammer 4 jeweils mit einer vorbestimmten Example filled in layers 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. 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 this state, the fall hammer 4 hits each with a predetermined
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 Stempel blocks 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 Stempel block 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.  Speed centrally on the die block 5, wherein it exerts on the stamp block a substantially straight, elastic shock. The mass of the drop hammer 4, the mass of the punch blocks 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 block his entire impulse on the punch 5 on the Bulk 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 1 1 angedeuteten Bereich um die Stoßachse 1 1 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. 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. Deviating from the above-described stamp block 5, a stamp block 5a shown in FIG. 3 has a slightly concave stamp face 9a, which ensures that the bulk material compaction concentrates on a region indicated by dashed lines 10 and 11 around the joint 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 of the degree of density in the adjacent compression sections 8a. 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.
