Description

Schräg- oder Treppenrost mit drehbar an Zapfen gelagerten Rostplatten, die in ihrer Mittellage dachziegelartig übereinanderliegen Die Erfindung betrifft einen Schräg- oder Treppenrost mit drehbar an Zapfen gelagerten Rostplatten, die in ihrer Mittellage dachziegelartig übereinanderliegen. Bei Rosten dieser Art wird die eine Hälfte der Platten gleichsinnig um ihren Zapfen ausgeschwungen, während dazwischen angeordnete Platten mit den angetriebenen Platten durch Gelenke verbunden sind, - welche Gelenke der Hitze des Brennstoffbettes ausgesetzt sind. Dies kann infolge ungleichmäßiger Ausdehnungen zu Formänderungen dieser Teile und damit zu Störungen in der Gangbarkeit führen.Inclined or step grate with grate plates rotatably mounted on pegs, which lie on top of each other like roof tiles in their central position. The invention relates to an inclined or step grate with grate plates rotatably mounted on pegs, which lie on top of each other in their central position like roof tiles. When rusting of this type will one half of the plates swung out in the same direction around their pegs, while plates arranged in between are connected to the driven plates by hinges - Which joints are exposed to the heat of the fuel bed. This can due to uneven expansion to changes in shape of these parts and thus to Disturbances in the maneuverability lead.

Der Erfindung gemäß wird jede der Rostplatten um einen unter ihrer Mitte außerhalb der Brennbahn angeordneten Zapfen drehbar gelagert und durch ein Gestänge so bewegt, daß die Rostplatten abwechselnd gegensinnig ausschwingen.According to the invention, each of the grate plates is one below their Center outside of the focal path arranged pin rotatably mounted and by a Linkage moved so that the grate plates swing out alternately in opposite directions.

Hierdurch wird die Anordnung von zwischen den angetriebenen Rostplatten eingehängten Zwischenplatten und damit von Gelenken in unmittelbarer Nähe der Brennbahn vermieden.This is the arrangement of between the driven grate plates suspended intermediate plates and thus of joints in the immediate vicinity of the focal path avoided.

In der Zeichnung ist die. Erfindung in einem Ausführungsbeispiel dargestellt. Hiernach besteht der Schräg- oder Treppenrost aus schwingbaren Rostplatten i; die ihren Drehpunkt bei 2 haben. Das Versetzen der Rostplatten i in eine schwingende Bewegung erfolgt von der Antriebsmaschine 3 aus, und zwar wird die Kraft der Antriebsmaschine mittels Schubstangen q, 8, der Hebel 9, der Welle io und der doppelarmigen Hebel i i auf die angegliederten Stützen 1z übertragen, die durch dieses Gestänge auf- und abwärts gehen und somit die Rostplatten i in eine schwingende Bewegung versetzen. Auf diese Weise entstehen in der Rostbahn, wie in der Abbildung gestrichelt angedeutet ist, abwechselnd Berge, Täler und Ebenen, wodurch der Vorteil erzielt wird, daß der Brennstoff auf seinem Wege vom Kohleneinschütttrichter 13 zum Ausbrandrost i ¢ kräftig umgeschichtet und damit die Brenngeschwindigkeit beschleunigt wird.In the drawing is the. Invention shown in one embodiment. According to this, the inclined or step grate consists of swinging grate plates i; which have their pivot point at 2. The grate plates i are set in an oscillating motion from the drive machine 3, namely the power of the drive machine is transmitted to the associated supports 1z by means of push rods q, 8, the lever 9, the shaft io and the double-armed lever ii this linkage go up and down and thus set the grate plates i in a swinging motion. In this manner occur in the grate path, as indicated by dashed lines in the figure, alternating mountains, valleys and planes, whereby the advantage is achieved reallocated ¢ vigorously that the fuel i on its way from Kohleneinschütttrichter 1 3 to the burn-out grate and thus accelerates the burn rate will.

Durch Einstellen der Hublänge der Schubstangen kann die Schwingbewegung der Rostplatten, die Kohlenförderung und die Durchmischung des Brennstoffes auf dem Rost je nach Bedarf geregelt werden.By adjusting the stroke length of the push rods, the oscillating movement the grate plates, the coal feed and the mixing of the fuel the grate can be regulated as required.

Durch eine Spindel 15 kann der Rost in seiner Neigung verstellt werden.The grate can be adjusted in its inclination by a spindle 1 5.
