Description

Die Erfindung betrifft eine Vorrichtung zum Verschieben einer Seitenwand eines Kokskohlestampfkastens im Anschluss an das Verdichten des Kohlekuchens.The invention relates to a device for displacing a side wall of a coking coal ramming box following the compression of the coal cake.

In Stampfkokereien wird gemahlene Einsatzkohle in Stampfformen zu Kohlekuchen verdichtet, die anschliessend mit geeigneten Setzvorrichtungen aus der Stampfform in die Ofenkammer geschoben werden.In tamped coking plants, ground charge coal is compressed into tampon molds to form coal cakes, which are then pushed out of the tampon mold into the furnace chamber using suitable setting devices.

Um eine Zerstörung des Kohlekuchens durch Wandhaftung beim Ausschieben aus der Stampfform zu vermeiden, wird nach dem Verdichten des Kohlekuchens eine Seitenwand der Stampfform etwas zurückgeschoben, bevor der Kuchen in die Ofenkammer gedrückt wird. Dazu greifen an der verschieblichen Seitenwand in einem gleichmässigen Raster verteilt Gelenkelemente an, die von entsprechenden horizontal angeordnetenn Exzenterwellen bewegt werden und dabei die verschiebliche Seitenwand mitnehmen. Die Exzenterwellen werden von einer gemeinsamen, senkrecht angeordneten Welle über Schnecken angetrieben, die jeweils in zugeordnete Schneckenräder der Exzenterwellen eingreifen. Die Antriebswelle selbst wird von einem Getriebemotor angetrieben.In order to prevent the coal cake from being destroyed by sticking to the wall when it is pushed out of the ramming mold, a side wall of the ramming mold is pushed back slightly after the coal cake has been compacted before the cake is pressed into the oven chamber. For this purpose, articulated elements act on the sliding side wall in a uniform grid, which are moved by corresponding horizontally arranged eccentric shafts and thereby take the sliding side wall with them. The eccentric shafts are driven by a common, vertically arranged shaft via worms, which each engage in assigned worm gears of the eccentric shafts. The drive shaft itself is driven by a geared motor.

Nachteilig bei der bekannten Konstruktion ist die sehr aufwendige und teure Antriebstechnik. Daneben weist diese Antriebskonstruktion wesentliche funktionelle Nachteile auf. Es ist praktisch nicht möglich, Exzenterwellen und Gelenkelemente so exakt zu montieren, dass alle Exzenter bei geschlossener Stampfform im Totpunkt stehen. Nur so aber kann ein Nachgeben der verschieblichen Seitenwand beim Verdichten der Kohle sicher vermiedenn werden. Weiterhin kann es zu Beschädigungen der verschieblichen Seitenwand kommen, wenn bereits Kohle in die Stampfform gefüllt wird oder wurde, während die Form noch nicht ganz geschlossen ist. Da der Überlastschalter des Antriebsmotors relativ träge anspricht, arbeitet der Antrieb kurzfristig mit Überlast gegen einen erhöhten Widerstand. Dies führt immer wieder zu Beschädigungen der verschieblichen Seitenwand, die das schwächste Glied in der Antriebskette ist.A disadvantage of the known construction is the very complex and expensive drive technology. In addition, this drive design has significant functional disadvantages. It is practically not possible to mount eccentric shafts and joint elements so precisely that all eccentrics are in dead center when the tamping mold is closed. This is the only way to reliably avoid giving in to the movable side wall when compacting the coal. Furthermore, the movable side wall can be damaged if coal is or has already been filled into the tamping mold while the mold is not yet completely closed. Since the overload switch of the drive motor responds relatively sluggishly, the drive works with overload for a short time against increased resistance. This leads to repeated damage to the sliding side wall, which is the weakest link in the drive chain.

Aufgabe der vorliegenden Erfindung ist es, eine einfache und wirtschaftliche Vorrichtung zur Verschiebung einer Seitenwand einer Stampfform zu schaffen, mit der zudem sowohl ein Nachgeben der verschieblichen Seitenwand beim Verdichten des Kohlekuchens als auch eine Beschädigung der verschieblichen Seitenwand beim Schliessen der Stampfform sicher vermieden werden kann.The object of the present invention is to provide a simple and economical device for displacing a side wall of a ramming mold, with which both a yielding of the displaceable side wall when compacting the coal cake and damage to the displaceable side wall when the ramming mold is closed can be reliably avoided.

Diese Aufgabe wird erfindungsgemäss gelöst durch einen Arbeitszylinder, der auf ein Verstellgestänge einwirkt, über das in Festpunkten gelagerte Zahnsegmente gedreht werden, die jeweils in Zahnräder von Exzenterwellen eingreifen, in denen Gelenkelemente gelagert sind, die in mehreren Ebenen an der verschiebbaren Seitenwand der Stampfform angreifen.This object is achieved according to the invention by a working cylinder, which acts on an adjustment linkage, via which toothed segments mounted in fixed points are rotated, each of which engages in the gears of eccentric shafts, in which joint elements are mounted, which engage in several planes on the displaceable side wall of the tamping mold.

Mit der erfindungsgemässen Konstruktion gelingt es, den Antrieb der verschieblichen Seitenwand wesentlich zu vereinfachen. Aufwendige und teure Teile, wie Getriebemotor, Schnecken und Schneckenräder werden durch einfache, billigere Teile wie Zylinder, stirnverzahnte Zahnsegmente und Zahnräder ersetzt. Durch ein Überdruckventil kann sicher verhindert werden, dass sich bei Störungen im Zylinder ein zu hoher Druck aufbaut, der zu Beschädigungen der verschieblichen Seitenwand oder der Verstellmechanik durch überhöhte Kräfte führen könnte. Der Abstand zwischen den Koppelpunkten der Schwingen zweier benachbarter Zahnsegmente mit dem Verstellgestänge ist, vorzugsweise kontinuierlich, veränderbar, so dass eine weitgehende Abstimmung der Winkellagen der Exzenterteile aller Exzenterwellen zueinander möglich ist.With the construction according to the invention, it is possible to significantly simplify the drive of the displaceable side wall. Elaborate and expensive parts such as gear motors, worms and worm gears are replaced by simple, cheaper parts such as cylinders, spur gear segments and gears. A pressure relief valve can reliably prevent excessive pressure from building up in the cylinder, which could lead to damage to the sliding side wall or the adjustment mechanism due to excessive forces. The distance between the coupling points of the rockers of two adjacent tooth segments with the adjusting linkage can be changed, preferably continuously, so that the angular positions of the eccentric parts of all eccentric shafts can be largely coordinated with one another.

Die Exzenterwellen sind unterteilt in Exzenterteile und Zwischenwellen, die durch Zahnkupplungen verbunden sind. Die Zahnkupplungen erlauben es, jeweils einander benachbarte Exzenterteile und Zwischenwellen in sehr kleinen Schritten, entsprechend der Zahnteilung der Kupplung, gegeneinander zu verdrehen. Damit gelingt es, zusammen mit der Verstellbarkeit der Abstände zwischen zwei Angriffspunkten des Verstellgestänges, alle Exzenterteile mit den an der verschieblichen Seitenwand angreifenden Gelenkelementen so zu justieren, dass sie bei geschlossener Stampfform im Totpunkt stehen und somit die verschiebliche Seitenwand beim Verdichten der Einsatzkohle nicht ausweichen kann.The eccentric shafts are divided into eccentric parts and intermediate shafts that are connected by toothed couplings. The toothed clutches allow eccentric parts and intermediate shafts that are adjacent to one another to be rotated relative to one another in very small steps, in accordance with the tooth pitch of the clutch. This makes it possible, together with the adjustability of the distances between two points of attack of the adjustment linkage, to adjust all eccentric parts with the joint elements acting on the sliding side wall in such a way that they are in dead center when the tamping mold is closed and thus the sliding side wall cannot evade when compacting the coal .

Die erfindungsgemässe Vorrichtung wird im folgenden anhand eines schematisch dargestellten Ausführungsbeispiels weiter erläutert.The device according to the invention is further explained below with the aid of a schematically illustrated exemplary embodiment.

Es zeigen:

  • Fig. 1 einen Querschnitt der erfindungsgemässen Vorrichtung
  • Fig. 2 eine Teilansicht einer Exzenterwelle.
Show it:
  • Fig. 1 shows a cross section of the device according to the invention
  • Fig. 2 is a partial view of an eccentric shaft.

An der verschieblichen Seitenwand 6 einer Stampfform 18 greifen in mehreren Ebenen Gelenkelemente 10 an. Alle Gelenkelemente 10 einer Ebene sind in Exzenterwellen 5 gelagert. Auf den Exzenterwellen 5 sind je ein Zahnrad 3 aufgesetzt, die mit jeweils zugeordneten Zahnsegmenten 4 in Eingriff stehen, die in Festpunkten 13 gehalten sind. Schwingen 14 der Zahnsegmente 4 sind mit einem Verstellgestänge 2 drehbar verbunden und durch diese parallel zueinander geführt. An einer verlängerten Schwinge 14a greift ein Arbeitszylinder 1, beispielsweise ein Hydraulikzylinder, an. Der Hub des Zylinders 1 ist mit den Hebellängen der Schwingen 14 und der Übersetzung zwischen Zahnsegmenten 4 und Zahnrädern 3 so abgestimmt, dass er einer Drehung der Exzenterwelle 5 von 180° entspricht, der wiederum ein Exzenterweg bzw. ein Verfahrweg e der verschieblichen Seitenwand 6 von ca. 30 mm zugeordnet ist. Um ein Nachgebenn der verschieblichen Seitenwand 6 beim Verdichten der Einsatzkohle 11 in der Stampfform 18 sicher zu vermeiden, ist es unabdingbar, alle Exzenterteile 7 bzw. die Gelenkelemente 10 bei geschlossener Stampfform 18 auf den sog. Totpunkt einzustellen. Dazu sind zwischen den einzelnen Koppelpunkten der Schwingen 14 der Zahnsegmente 4 mit dem Verstellgestänge 2 Spannelemente 16, beispielsweise Spannschlösser, angebracht, die es ermöglichen, jeweils den Abstand zweier benachbarter Koppelpunkte zu verändern. Dadurch können in einfacher Weise die Winkellagen der Exzenterwellen 5 weitgehend korrigiert und aufeinander abgestimmt werden. Zusätzlich sind die Exzenterwellen 5 in Exzenterteile 7 und Zwischenwellen 15 (vgl. Fig. 2) unterteilt, die durch Zahnkupplungen 17 gekoppelt sind. Diese Unterteilung der Exzenterwellen 5 erlaubt nunmehr die endgültige, exakte Einstellung aller Exzenterteile 7, da diese gegenüber den benachbarten Zwischenwellenn 15 um kleine, der Zahnteilung der Zahnkupplungen 17 entsprechende Winkelbeträge verdreht werden können.Joint elements 10 act on the displaceable side wall 6 of a ramming mold 18 in several planes. All joint elements 10 of a plane are supported in eccentric shafts 5. On the eccentric shafts 5 a gear 3 is placed, which are in engagement with respectively assigned tooth segments 4, which are held in fixed points 13. Swing 14 of the toothed segments 4 are rotatably connected to an adjustment linkage 2 and guided parallel to one another through this. A working cylinder 1, for example a hydraulic cylinder, acts on an extended rocker 14a. The stroke of the cylinder 1 is coordinated with the lever lengths of the rockers 14 and the translation between toothed segments 4 and gearwheels 3 so that it corresponds to a rotation of the eccentric shaft 5 of 180 °, which in turn is an eccentric path or a travel path e of the movable side wall 6 of 30 mm is assigned. In order to reliably prevent the displaceable side wall 6 from yielding when the insert coal 11 is compressed in the tamping mold 18, it is essential to set all the eccentric parts 7 or the joint elements 10 to the so-called dead center when the tamping mold 18 is closed. For this purpose, clamping elements 16, for example turnbuckles, are attached between the individual coupling points of the rockers 14 of the toothed segments 4 with the adjusting linkage 2, which make it possible to change the distance between two adjacent coupling points. This allows the angular positions of the eccentric shafts in a simple manner 5 largely corrected and coordinated. In addition, the eccentric shafts 5 are divided into eccentric parts 7 and intermediate shafts 15 (see FIG. 2), which are coupled by toothed couplings 17. This subdivision of the eccentric shafts 5 now allows the final, exact setting of all eccentric parts 7, since these can be rotated relative to the adjacent intermediate shafts 15 by small angular amounts corresponding to the tooth pitch of the toothed couplings 17.

Im Beispiel der Fig. 1 greift die Kolbenstange des Arbeitszylinders 1 an der verlängerten mittleren Schwinge 14a an. Der Arbeitszylinder 1 ist sowohl an seiner Abstützung als auch mit der Schwinge 14a drehbeweglich verbunden und durch ein Überdruckventil gegen Überlast geschützt.In the example of FIG. 1, the piston rod of the working cylinder 1 engages the extended middle rocker 14a. The working cylinder 1 is rotatably connected both at its support and to the rocker 14a and is protected against overload by a pressure relief valve.

Bei geschlossener Stampfform 18 ist die Kolbenstange des Arbeitszylinders 1 ausgefahren (Position b). Zum Öffnen der Stampfform 18 wird die Kolbenstange in den Arbeitszylinder 1 eingezogen (Position a). Zur Verdeutlichung sind in Fig. 1 die Elemente Zahnritzel 4a und Exzenterteil 7a der unteren Antriebsreihe in den der geöffneten Stampfform 18 entsprechenden Positionen gezeichnet.

When the tamping mold 18 is closed, the piston rod of the working cylinder 1 is extended (position b). To open the ramming mold 18, the piston rod is drawn into the working cylinder 1 (position a). For clarification, the elements pinion 4a and eccentric part 7a of the lower drive row are drawn in the positions corresponding to the opened tamping mold 18 in FIG. 1.
