Abstract

The nozzle (1) may be mounted on two swiveling rods (2), and may trace a predetermined zigzag path (6) over a square area (4) on the wall of the boiler. Links connect the nozzle to two rotary drives (3,4) with elongated levers. Rotary motion of the rods moves the links and can adjust the position of the nozzle in X and Y directions.

Description

Die Erfindung betrifft eine Verbesserung einer Reinigungseinrichtung für Feuerungen mit verschmutzten Abgasen. Bei diesen Feuerungen werden die Heizflächen durch Ablagerungen verschmutzt. Durch diese Verschmutzung verringert sich der Wärmetransport. Die Tauscherflächen müssen daher regelmäßig gereinigt werden. Als Nachfolger der händischen Reinigung sind heute Maschinen im Einsatz. Diese Maschinen reinigen mittels eines Reinigungsmediums die Heizflächen. Das Reinigungsmedium wird z.B. mittels einer Düse auf die Heizflächen gespritzt. Die Bewegung wird durch zwei Stellmotore erreicht, die in dem Patent DE 100 09 818 A1 beschrieben sind.The invention relates to an improvement of a cleaning device for furnaces with polluted exhaust gases. With these furnaces, the heating surfaces are contaminated by deposits. This pollution reduces the heat transport. The exchanger surfaces must therefore be cleaned regularly. Today, machines are used as the successor to manual cleaning. These machines use a cleaning medium to clean the heating surfaces. The cleaning medium is sprayed onto the heating surfaces using a nozzle, for example. The movement is achieved by two servomotors, which are in the patent DE 100 09 818 A1 are described.

Der Nachteil ist, dass ein Motor auf der Achse des ersten Antriebes ist. Dadurch ist der Einsatz von beweglichen Kabeln notwendig. Durch die Konstruktion eines Spindelantriebes ist ein Eindringen von Schmutz in die Antriebseinheit unvermeidlich. Auch ist der Verschleiß in besonders heißen Bereichen, z.B. Wand eines mit Kohle befeuerten Kessels, sehr hoch.The disadvantage is that an engine is on the axis of the first drive. This makes the use of moving cables necessary. Through the construction of a spindle drive the ingress of dirt into the drive unit is inevitable. Also is the wear in especially hot Areas, e.g. Wall of a coal-fired boiler, very high.

Diese Erfindung stellt jetzt eine Weiterentwicklung der bekannten Maschinen dar. Das Blasrohr (1) besitzt zwei Gelenke (2) für die beiden Antriebe (3 und 4). Bei den Antrieben handelt es sich um zwei Schwenkantriebe. Aus den Schwenkantrieben tritt eine Welle aus und dieser ist somit gegen Verschmutzungen geschützt. Von den Schwenkantrieben wird durch eine Gelenkstange ( 7) das Blasrohr (1) bewegt. Durch die Anordnung der zwei Schwenkantriebe ist es möglich, den gesamten Bereich (5) der zu reinigenden Kesselwand gesteuert abzufahren (6).This invention now represents a further development of the known machines. 1 ) has two joints ( 2 ) for the two drives ( 3 and 4 ). The drives are two part-turn actuators. A shaft emerges from the quarter turn actuators and is therefore protected against contamination. A swivel rod ( 7 ) the blowpipe ( 1 ) emotional. The arrangement of the two rotary actuators enables the entire area ( 5 ) to control the boiler wall to be cleaned in a controlled manner ( 6 ).

Als Beispiel sind drei beliebige Positionen dargestellt. Pos. 1, Pos. 2 und Pos. 3.As an example, any three Positions shown. Pos. 1, Pos. 2 and Pos. 3.

Die Erfindung wird nachstehend anhand der in den Zeichnungen dargestellten Ausführungsbeispielen erläutert.The invention is illustrated below of the embodiments illustrated in the drawings.
