Abstract
Description
Die Erfindung betrifft eine Planierstange für Verkokungsöfen zum Einebnen der sich unter den Füllöchern der Ofenkammer während des Füllvorganges bildenden Kohleschüttkegel, bestehend aus sich über die gesamte Länge der Ofenkammer erstreckenden und in einem von der Breite der Ofenkammer abhängigen Abstand parallel zueinander angeordneten sowie miteinander verbundenen Tragelementen.The invention relates to a leveling rod for coking ovens Leveling the under the filling holes of the furnace chamber during the Filling process forming coal cone, consisting of itself over the entire length of the furnace chamber and in one of the Width of the furnace chamber dependent distance parallel to each other arranged and interconnected support elements.
Aus der DE 40 34 341 C2 ist eine gattungsgemäße Planierstange bekannt, die aus in Ofenlängsrichtung und parallel zueinander angeordneten senkrechten Blechen besteht, wobei in dem durch die senkrechten Bleche begrenzten Zwischenraum in regelmäßigen Abständen querstehende Kohlemitnehmer angeordnet sind. Durch das Einfahren derartiger Planierstangen während des Füllvorganges in die Ofenkammer wird der freie Gassammelraum über der Kohle in der Regel um ca. 60 % blockiert (vgl. beigefügte Figur 1). Hieraus ergeben sich häufig zum Ende des Füllvorganges Verstopfungen innerhalb des Gassammelraumes und damit verbunden starke Emissionen, da die Füllgase nicht mehr frei zur Absaugestelle, d. h. dem Steigerohr oder dem Gasüberleitrohr, abgeführt werden können.From DE 40 34 341 C2 a generic leveling rod is known which are arranged in the longitudinal direction of the furnace and parallel to each other there are vertical sheets, in which through the vertical sheets limited space transversely spaced at regular intervals Coal carriers are arranged. By retracting such leveling bars during the filling process in the furnace chamber the free one Gas collecting space above the coal is usually blocked by approx. 60% (cf. attached figure 1). This often results at the end of the filling process Blockages within the gas collection space and associated with it strong emissions, since the filling gases are no longer free to the extraction point, d. H. the riser pipe or the gas transfer pipe can.
In der DE-A 10 58 018 ist weiterhin eine Planierstange für Koksöfen beschrieben, deren in den Ofen einfahrbarer Teil zwei Seitenwangen mit den Abständen angeordneten stegartigen Verbindungselementen aufweist. Die beiden Seitenwangen sind hierbei als geschlossene Hohlträger mit gleichmäßig gewölbten Schalenblechen ausgebildet. Auch heirbei kann es aufgrund der durchgehenden seitlichen Bleche zu Verstopfungen und dadurch verursacht zu Emissionen kommen. DE-A 10 58 018 also describes a leveling bar for coke ovens, whose part retractable into the oven has two side walls with the Has spaced web-like connecting elements. The two side walls are included as closed hollow beams uniformly curved shell plates. It can also be used here due to the continuous side plates to blockages and thereby causes emissions to come.
Der Erfindung liegt nunmehr die Aufgabe zugrunde, eine neue Konstruktion für die Planierstange vorzuschlagen, bei der mögichst immer die Füllgase ungehindert abgezogen werden können.The invention is based on the object of a new construction to propose for the leveling bar, where the filling gases are always possible can be withdrawn unhindered.

Bei der erfindungsgemäßen Planierstange handelt es sich im wesentlichen um einen im Querschnitt dreieckigen Fachwerkträger, der während des Planiervorganges den Gassammelraum nur zu ca. 25 % blockiert. Dadurch wird ein Verstopfen des Gassammelraumes mit Kohle weitgehend verhindert und die beim Füllvorgang entstehenden Füllgase können in Ofen längsrichtung ungehindert zu den jeweiligen Absaugestellen geführt werden. Durch die fachwerkartige Konstruktion mit nur in regelmäßigen Abständen angeordneten Querstreben und einzelnen, diagonal verlaufenden Tragstreben ist außerdem auch eine seitliche Durchströmung der Planierstange, d. h. quer zur Ofenlängsrichtung, ohne weiteres möglich.The leveling bar according to the invention is essentially around a truss with a triangular cross-section, which during of the leveling process only blocked the gas collecting space by approx. 25%. This largely clogs the gas collecting space with coal prevented and the filling gases generated during the filling process can Unhindered in the longitudinal direction of the furnace to the respective extraction points will. Due to the half-timbered construction with only regular Distances arranged cross struts and individual, diagonally running Support struts are also a side flow the leveling bar, d. H. transverse to the longitudinal direction of the furnace, easily possible.
Die einzelnen Konstruktionselemente der Planierstange bestehen zweckmäßigerweise aus handelsüblichen Rohren mit in allen Bereichen gleichgroßen Durchmessem. Auf diese Weise wird eine preiswerte und aufgrund der Hohlquerschnitte relativ leichte und trotzdem stabile Konstruktion der Planierstange erreicht.The individual construction elements of the leveling rod exist expediently from commercially available pipes with in all areas equally large diameters. In this way it becomes an inexpensive and due to the hollow cross-sections, the construction is relatively light and nevertheless stable reached the leveling bar.
