Description

Treppenrost mit beweglichen und festen Roststufengruppen. Die Erfindung betrifft einen Treppenrost mit beweglichen und feststehenden Roststufengruppen. Um bei Treppenrosten dieser Art unter Beibehaltung der- Beobachtungsmöglichkeit des Feuers von der Rückseite her die besonders bei sandigem Brennstoff vorliegende Gefahr zu beseitigen, daß beim Verschieben der Roststufen in-die Feuerung hinein Brennstoff rückwärts über die Rostplatten hinweg in den Aschenfall gelangt, setzt sich gemäß der Erfindung der Rost aus zwei verschiedenen Arten von Roststufengruppen zusammen. Die beweglichen Stufengruppen sind treppenförmig ausgebildet und haben im senkrechten Teil der Treppe düsenartige Schlitze, die unter Aufrechterhaltung eines genügenden. Luftzutritts einen Durchfall des Brennstoffes verhindern. Die feststehenden oder nur schwingenden Stufengruppen bestehen aus einfachen Rostpl attenwie bei einem gewöhnlichen Treppenrost.Step grate with movable and fixed grate step groups. The invention relates to a step grate with movable and fixed grate step groups. In order to use step gratings of this type while maintaining the possibility of observation of the fire from the rear is the one present especially with sandy fuel To eliminate the risk of moving the grate steps into the furnace Fuel backwards over the grate plates into the ash case, sets According to the invention, the grate consists of two different types of grate step groups together. The movable groups of steps are step-shaped and have in the vertical part of the stairs nozzle-like slots, which under maintenance one sufficient. Prevent the fuel from leaking through the air. the Fixed or only vibrating step groups consist of simple Rostpl as with an ordinary stair grate.

In der Zeichnung ist der neue Rost in einem Ausführungsbeispiel in zwei Abbildungen dargestellt.In the drawing, the new grate is shown in one embodiment shown in two figures.

Auf einem feststehenden Rahmen i sind Rohre a befestigt. Über diese sind an ihrem rückwärtigen Ende Rostkörper 3 gehakt, die aus einer Anzahl treppenförmig angebrachter Rostplatten ¢ bestehen. Zwischen ihnen ist wie üblich so viel Raum vorhanden, daß der Rost von der Rückseite aus überwacht und mittels Schürstange in Ordnung gebracht ,werden kann.Pipes a are attached to a fixed frame i. About these are hooked at their rear end grate body 3, the staircase-shaped from a number attached grate plates ¢ exist. As usual, there is so much space between them available that the grate is monitored from the rear and by means of a poker can be put in order.

Die beweglichen Rostkörper 5 sind über Rohre 6 gehakt, die von Laschen 7 getragen werden, die ihrerseits an einem Schwingrahmen 8 angebracht sind. Diese Rostkörper 5 sind als geschlossene Treppe ausgebildet. Ihr senkrechter Teilg hat düsenförmige Spalten io, die so bemessen sind, daß genügend Luft eintreten, aber bei der Bewegung des Rostkörpers dennoch kein Brennstoff heraustreten kann.The movable grate body 5 are hooked over tubes 6 by lugs 7, which in turn are attached to an oscillating frame 8. These Grate body 5 are designed as a closed staircase. Your vertical part has nozzle-shaped gaps io, which are dimensioned so that enough air can enter, but However, no fuel can escape when the grate body moves.
