Description

Bei Planrosten, auf welchen der Brennstoff durch einen auf der Rostfläche hin und her laufenden Stößel geschürt und gefördert wird, ist es bekannt, den sich quer über den Rost erstreckenden Stößel in der Mitte zu fassen und ihn durch eine unterhalb des Rostes gelegene Kette zu bewegen. Dabei ist in der Rostfläche ein Längsspalt vorgesehen, durch welchen das den Förderstößel tragende Glied hindurchreicht und welcher vor und hinter dem Stößel durch an der Förderkette befestigte lamellenartige Glieder ausgefüllt wird.In the case of flat grids, on which the fuel is placed on the grate surface back and forth running ram is stoked and promoted, it is known to be across the grate extending plunger in the middle and push it through a to move the chain below the grate. There is a in the grate surface A longitudinal gap is provided through which the member carrying the conveyor ram extends and which in front of and behind the ram by lamellar fastened to the conveyor chain Limits is filled out.

Bei einer solchen Ausführung ist es unvermeidlich, daß bei dem häufigen Hinundherlaufen des Förderstößels, wobei auch die Füllglieder hin und her laufen, durch das notwendige Spiel der Füllglieder innerhalb des Bewegungsspaltes Kohle- und Ascheteilchen nach unten durchfallen und auf die Kette gelangen, wodurch diese verschmutzt und vorschnell verschlissen wird. Nach der Erfindung wird dieses dadurch behoben, daß die Förderkette in ein em dachartig ausgebildeten Gehäuse läuft und die zur Rostfläche nach oben heraustretenden Füllglieder wie auch das den Stößel tragende Halteglied oberhalb des Daches mit über die Dachschräge ausladenden Firsten versehen sind, so daß der von oben kommende Durchfall an diesen Firsten abgleitet und über die Schräge des den Kettenkanal überdeckenden Daches nach außen abfällt.With such an implementation, it is inevitable that with the frequent Running back and forth of the delivery ram, whereby the filling members also run back and forth, due to the necessary play of the filling links within the movement gap carbon and ash particles fall through and get onto the chain, causing it becomes dirty and worn out prematurely. According to the invention, this is thereby fixed that the conveyor chain runs in an em roof-like housing and the filling members protruding upwards towards the grate surface as well as the plunger load-bearing support member above the roof with ridges protruding over the sloping roof are provided so that the diarrhea coming from above slides off these ridges and slopes outwards over the slope of the roof covering the chain channel.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel im senkrechten Querschnitt dargestellt. Auf dem beliebig ausgebildeten, hier als Kühlrost dargestellten Brennrost i läuft der sich quer über die Roststäbe erstreckende Schür- und Förderstößel z senkrecht zur Bildebene hin und her. Der Stößel a ist an einem hier nicht dargestellten Halteglied befestigt, welches von der Kette 3 hin und her gezogen wird. An dieser Kette 3 sind Füllglieder q. angebracht, welche bis zur Oberkante des Rostes i reichen und den für das Halteglied notwendigen Spalt in der Rostoberfläche ausfüllen. Das Gehäuse 5 für die Kettenlaufbahn ist in seinem oberen Teil 6 dachförmig ausgebildet, und diie Füllglieder q. tragen ebenso wie das Halteglied für den Stößel oberhalb des Daches 6 Firste 7, welche die Spitze des Daches überdecken. Der von oben kommende Kohlendurchfall rutscht gemäß den Pfeilen ä über die Firste 7 und die Dachschräge 6 seitlirh ab und gelangt nach unten.In the drawing, the invention is shown in one embodiment vertical cross-section shown. On the arbitrarily designed, here as a cooling grate the burner grate i shown, the stoke running transversely over the grate bars and delivery ram z to and fro perpendicular to the plane of the drawing. The plunger a is on one here not shown holding member attached, which of the chain 3 back and forth is pulled. On this chain 3 are filling links q. attached, which up to the top edge of the grate i and the gap in the grate surface necessary for the holding member to complete. The housing 5 for the chain track is roof-shaped in its upper part 6 formed, and the filling members q. wear as well as the holding member for the plunger above the roof 6 ridges 7, which cover the top of the roof. The from Coal diarrhea coming from above slides over the roofs 7 and according to the arrows ä the sloping roof 6 from the side and comes down.

Durch diese Einrichtung wird die Kette 3 vor jeder Verschmutzung und Beschädigung durch Kohle- oder Schlackenteilchen geschützt.By this device, the chain 3 from any contamination and Damage protected by coal or slag particles.
