Description
Als Trogkettenförderer ausgebildete Aufgabe für Mühlen Staubfeuerungen mit Einblasemühlen erfordern eine gleichmäßige und leicht regelbare Aufgabevorrichtung. Mit zunehmender Verwendung von Brennstaubfeuerungen mit Einblasemühlen bei minderwertigen Kohlen werden an die Kohlenaufgabevorrichtungen erhöhte Ansprüche gestellt.Trained as a trough chain conveyor for pulverized mills with injection mills require a uniform and easily controllable feeding device. With the increasing use of pulverized fuel furnaces with injection mills in the case of inferior ones Coals are subject to increased demands on the coal feed devices.
In vielen Fällen ist zwischen dem Bunkerauslauf und dem Kohleneinfall in die betreffende Mühle eine gewisse Entfernung zu überbrücken, so daß als Kohlenaufgabe Vorrichtungen zur Anwendung kommen müssen, die gleichzeitig als Fördermittel dienen. Es kommen in derartigen Fällen nur Förderbänder oder Förderketten in Betracht. Dia erstere nicht für alle Brennstoffe und örtlichen Verhältnisse geeignet sind, wird der Kettenförderer in steigendem Maße für derartige Zwecke verwendet.In many cases there is between the bunker outlet and the coal inlet to bridge a certain distance in the mill in question, so that as coal feed Devices must be used that also serve as funding. In such cases, only conveyor belts or conveyor chains come into consideration. slide the former are not suitable for all fuels and local conditions the chain conveyor is increasingly being used for such purposes.
Bei zum Schmieren und Anbacken neigenden Kohlen hat sich als nachteilig herausgestellt, daß die Förderketten nicht in der Lage sind, die Böden von anhaftender Kohle frei zu machen. Die Folge davon ist, daß die Kette über die anhaftende Kohle hinweggleitet und die festhaftenden Kohlenschichten allmählich ansteigen. Hierdurch geht zunächst die Durchsatzleistung der Aufgabevorrichtung zurück, und außerdem steigt hierdurch der Leistungsbedarf.In the case of coals that tend to smear and stick on, has been found to be disadvantageous found that the conveyor chains are not able to keep the floors from sticking To free up coal. The consequence of this is that the chain over the adhering coal slides away and the firmly adhering layers of coal gradually rise. Through this the throughput of the feeder initially goes down, and also This increases the power requirement.
Man hat daher versucht, die Förderketten mit entsprechenden Kratzern zu versehen, um die Böden frei zu halten, ohne daß jedoch ein wirksamer Erfolg erzielt werden konnte. Vorteilhafter wirkten in der Beziehung Leitschienen, die das Ausweichen der Kette nach oben verhinderten und dadurch das Anwachsen von Kohle auf dem Boden unterbanden. Derartige Leitschienen haben jedoch den Nachteil, daß das Anbacken von Kohle an den Seitenwänden der Tröge gefördert wird, weil die Bewegung der Kette auf die Kohle nicht mehr wirksam ist.Attempts have therefore been made to scratch the conveyor chains with appropriate scratches to provide to keep the floors free, but without achieving any effective success could be. Guard rails, which allow evasive action, were more advantageous in this regard the chain upwards and thereby the growth of coal on the ground suppressed. However, such guide rails have the disadvantage that the caking is conveyed by coal on the side walls of the troughs because of the movement of the chain on the coal is no longer effective.
Erfindungsgemäß werden daher unmittelbar über der Oberkante der Kette
nur kurze rechteckige Führungsleisten angeordnet. Um ein Anlaufen der Kette gegen
diese Führungsleisten zu verhindern, werden sie auf der Ein-
In Abb. z sind die Führungsstücke in der Draufsicht dargestellt.In Fig. Z, the guide pieces are shown in plan view.
