Description
Rost aus Platten mit Luftdurchtrittsöffnungen und Abdeckkörpern über den Öffnungen Die Erfindung betrifft einen Rost aus Platten mit Luftdurchtrittsöffnungen und Abdeckkörpern über den Öffnungen. Erfindungsgemäß werden über den Öffnungen lose, schirmförmige Abdeckkörper angeordnet, die mit Bolzen mit Spiel in die Bohrungen der Rostplatte hineinragen, wobei die Abdeckkörper mit Vorsprüngen auf der Rostplatte ruhen, so daß waagerechte Luftschlitze zwischen der Rostplattenfläche und der unteren Seite der Abdeckkörper gebildet werden.Grate made of plates with air passage openings and cover bodies over the openings The invention relates to a grate made of plates with air passage openings and cover bodies over the openings. According to the invention are above the openings loose, umbrella-shaped cover body arranged with bolts with play in the holes the grate plate protrude, wherein the cover body with projections on the grate plate rest, so that horizontal air slots between the grate plate surface and the lower Side of the cover are formed.
Durch diese Anordnung wird gegenüber bekannten Ausführungen, bei welchen die Abdeckkörper festgeschraubt sind oder mit dem Rost aus einem Stück bestehen, der Vorteil erzielt, daß eine unabhängige Wärmedehnung der Rostteile stattfindet, so daß keine Spannungen auftreten, die zum Zerreißen der Verbindungsstege zwischen Platte ünd Abcdeckkörpern und damit zum Abspringen der letzteren führen können. Bei Verwendung der Platten bei Wanderrosten werden die Bolzen durch Splinte gegen Herausfallen in der unteren Rostbahn gesichert.This arrangement is compared to known designs in which the cover bodies are screwed on or consist of one piece with the grate, the advantage achieved that an independent thermal expansion of the grate parts takes place, so that no stresses occur that can tear the connecting webs between Plate and cover bodies and thus can lead to the latter jumping off. When using the plates for traveling grids, the bolts are locked with split pins Falling out secured in the lower grate track.
Abb. i der Zeichnung zeigt ein Ausführungsbeispiel des neuen Rostes teilweise im Schnitt, Abb.2 in Draufsicht. Die Rostplatte g als fester Rost oder auch als Teil eines Wanderrostes ist mit Bohrungen f versehen, über denen schirmförmige Abdeckkörper a angeordnet sind. Diese Körper d reichen mit Bolzen b durch die Bohrungen f und können bei Verwendung der Platten bei einem Wanderrost durch Splinte d gegen Herausfallen gesichert sein. Sie ruhen mit Vorsprüngen c auf der Rostplatte, so daß waagerechte Luftzuführungsschlitze zwischen ihnen und der Rostplatte frei bleiben. Zwischen dem Bolzen b und den Wandungen der Bohrung f ist genügend Spiel für den Luftdurchtritt gelassen. Um das Hindurchfallen des feinkörnigen Brennstoffs durch die Rostbohrungen vollkommen auszuschließen, können die Ränder der Bohrungen e hochgezogen werden. Zweckmäßig wird der Raum innerhalb des schirmförmigen Teils gegenüber dem ringförmigen Austrittsquerschnitt im Schaft zur Herabminderung der Strömungsgeschwindigkeit der Luft erweitert.Fig. I of the drawing shows an embodiment of the new grate partly in section, Fig. 2 in plan view. The grate plate g as a solid grate or also as part of a traveling grate is provided with holes f, over which umbrella-shaped Cover body a are arranged. These bodies d reach through the holes with bolts b f and can be countered by cotter pins d when using the plates with a traveling grate Be secured from falling out. They rest with projections c on the grate plate, see above that horizontal air supply slots remain free between them and the grate plate. There is enough play for the between the bolt b and the walls of the hole f Allowed air to pass through. To prevent the fine-grained fuel from falling through To completely exclude the rust bores, the edges of the bores e can be pulled up will. The space within the umbrella-shaped part is expedient compared to the annular outlet cross-section in the shaft to reduce the flow velocity the air expands.
