Description

Wassergekühlter Treppenrost Die Erfindung betrifft einen wassergekühlten Treppenrost mit beweglichen Rostgliedern, bei welchem das Wasser .die Stufen der Reihe nach durchläuft. Sie besteht darin, daß jedes der abwechselnd feststehenden und waagerecht verschiebbaren Rostglieder auf seiner Oberseite einen festliegenden. Deckel, auf welchem der darüberliegende Roststab gleitet, und einen verschiebbaren aufliegenden Rostdeckel, durch welchen die Ableitung des Wassers von dem oberen zu dem Barunterliegenden Rostglied geht, besitzt.Water-cooled step grating The invention relates to a water-cooled one Step grate with movable grate members, in which the water. The steps of the Runs through in sequence. It consists in that each of the alternately fixed and horizontally displaceable grate members on its top a fixed. Lid, on which the grate bar above slides, and a slidable one overlying grate cover, through which the drainage of the water from the upper goes to the grate link below the bar.

Durch diese Bauart wird erreicht, daß der Rostdurchfall nach Möglichkeit von den Wassertrögen ferngehalten wird, während sich die Roststufen gegenseitig verschieben. Außerdem wird erreicht, daß nach Abheben der verschiebbaren und der festen Deckel der gesamte Trog offen ist, so d.aß er bequem vom Schlamm u. dgl. gereinigt werden kann.This design ensures that the rust diarrhea as far as possible is kept away from the water troughs, while the grate steps are mutually exclusive move. It is also achieved that after lifting the sliding and the the entire trough is open, so that it can easily be removed from the mud and the like. can be cleaned.

In der Zeichnung ist in Abb. i ein Teil des neuen Rostes in senkrechtem Längsschnitt des Rostes, in Abb. 2 in Aufsicht dargestellt. Der Rost besteht aus den festliegenden Stufen a und den beweglichen Stufen b. Der obersten Stufe wird das Kühlwasser durch ein Rohr c zugeführt, es gelangt in den querlaufenden Trog d, der durch einen lose aufliegenden Deckel e verschlossen ist. An, dem Trog d sind nach vorn die kammartigen Roststäbe f angegossen, die an ihrer Spitze durch eine durchlaufende Querleiste g verbunden sein können. Das Zulaufrohr c befindet sich an dem einen Ende des Troges, d, an dem anderen Ende befindet sich das Ablaufrohr h, welches für den nächsten Trog d' das Zulaufrohr bildet. Dessen Ablaufrohr h' befindet sich wiederum am entgegengesetzten Ende, so daß das Wasser gemäß den in Abb. 2 gezeigten Pfeilen immer die Tröge ihrer ganzen Länge nach .durchlaufen muß. Die Ausbildung der übrigen Stufen geschieht, wie die Abbildungen zeigen, in gleicher Weise. Die Deckel e, e' usw. tragen an ihrer linken Seite nach oben verdeckte, nach der Seite offene Kanäle oder Öffnungen i, durch welche der in den Trögen erzeugte Dampf nach oben austreten. und die Roststäbe f, f' usw. kühlen kann. Die Roststäbe f schleifen mit ihrem unteren Ende auf den Deckeln e der Tröge, werden also auch durch Berührung mit diesen gekühlten Dekkeln ihrerseits gekühlt. Durch diese Maßnahme wird eine sehr wirksame Kühlung dieser Roststäbe f von beiden Enden aus bewirkt.In the drawing, a part of the new grate is shown in a vertical longitudinal section of the grate in Fig. 1, and in Fig. 2 in a top view. The grate consists of the fixed steps a and the movable steps b. The cooling water is fed to the uppermost stage through a pipe c, it enters the transverse trough d, which is closed by a loosely lying lid e. At the front of the trough d, the comb-like grate bars f are cast, which can be connected at their tip by a continuous transverse bar g. The inlet pipe c is located at one end of the trough, d, at the other end is the outlet pipe h, which forms the inlet pipe for the next trough d '. Its drainage pipe h 'is again at the opposite end, so that the water must always pass through the troughs along their entire length according to the arrows shown in Fig. 2. As the figures show, the other stages are formed in the same way. The lids e, e 'etc. have on their left side covered upwards channels or openings i which are open to the side and through which the steam generated in the troughs escape upwards. and can cool the grate bars f, f 'etc. The grate bars f grind with their lower end on the lids e of the troughs, so they are in turn cooled by contact with these cooled lids. This measure brings about a very effective cooling of these grate bars f from both ends.

Um die Tröge auch an der Zuführungsstelle des Wassers von einem Trog zum arideren gut gegen Aschendurchfall zu schützen, sind auf ihnen lose Deckel h, k' angeordnet, durch welche :die Rohre h hindurchreichen und die von diesen Rohren mitgeschleppt werden. Diese Deckel k sind so groß, daß sie in jeder Stellung des Rostes den Trogansatz in, der für die Zuführung des Wassers dient, vollständig bedecken.In order to protect the troughs well against ash diarrhea at the point where the water is supplied from one trough to the other, loose covers h, k ' are arranged on them, through which: the pipes h extend and which are carried along by these pipes. These covers k are so large that they completely cover the trough attachment in which the water is supplied in every position of the grate.
