Description

Rollenkranz für Regenerativ-Vorwärmer Die Lagerung eines Läufers innerhalb eines Regenerativ-Vorwärmers kann zur Verminderung gleitender Reibung durch Rollenkränze erfolgen, wobei allerdings der starke Staubanfall eine Schmierung verbietet.Roller ring for regenerative preheater The storage of a rotor within a regenerative preheater can be used to reduce sliding friction by means of roller and cage assemblies take place, however, the heavy accumulation of dust forbids lubrication.

In diesen Fällen hat man bisher der Verstaubungsgefahr kein besonderes Augenmerk zugewandt, weil die Konstruktion als solche gegen Abnutzung ausreichend gesichert erschien. Insbesondere hat man keinen Bedacht darauf genommen, Staubansammlungen auf den Laufbahnen für die Drehkörper zu verhindern, weil man der Auffassung war, daß durch die Bewegung der Drehkörper selbst derartige Staubansammlungen vermieden oder rechtzeitig beiseitegeschoben würden.In these cases, there is no particular risk of dust accumulation Attention turned because the construction as such is sufficient against wear and tear appeared secured. In particular, no attention was paid to dust accumulation to prevent on the raceways for the rotating body, because it was believed that such accumulations of dust avoided by the movement of the rotating body itself or would be pushed aside in time.

Gemäß der Erfindung soll nun die Entstehung derartiger Staubansammlungen auf den Führungsbahnen von Rollenkränzen für Regenerativ-Vorwärmer dadurch vermieden werden, daß die untere Kugelbahn durch Abwälzflächen gebildet wird, die gegenüber der Waagerechten einen Winkel bilden, der größer ist als der Schüttwinkel des Staubes. Es versteht sich hierbei, daß z. B. bei Verwendung von Kugeln diese beiden Abwälzflächen einander zugeneigt sein werden. Man wird dann, falls nicht besondere Verhältnisse vorliegen, die beiden Winkel der Abwälzflächen gleich groß halten. Man kann jedoch auch nur eine Abwälzfläche vorsehen, die dann gemäß der Lehre der Erfindung unter dem Schüttwinkel oder einem größeren Winkel anzuordnen wäre.According to the invention, the formation of such dust accumulations should now on the guideways of roller and cage assemblies for regenerative preheaters are thus avoided be that the lower ball track is formed by rolling surfaces that are opposite the horizontal form an angle that is greater than the angle of repose of the dust. It goes without saying that, for. B. when using balls these two rolling surfaces will be inclined to one another. Then, if not special circumstances present, keep the two angles of the rolling surfaces the same. However, one can also provide only one rolling surface, which then according to the teaching of the invention under the angle of repose or a larger angle would be to be arranged.

Die Abwälzkörper können sich auch auf den Kanten zweier Schneiden oder den Mantellinien gekrümmter Flächen abwälzen.The rolling elements can also be on the edges of two cutting edges or roll off the surface lines of curved surfaces.

Verwendet man mehrere Abwälzflächen, so soll weiterhin nach der Erfindung zwischen den beiden Flächen ein Spalt frei gelassen werden, der größer ist als der größten Kornabmessung des Staubes entspricht. Es versteht sich, daß, sofern Staub vorliegt, der zu Zusammenballung neigt, dieser Spalt so groß gehalten werden muß, daß auch die größten zu erwartenden Zusammenballungen noch durch ihn ungehindert hindurchtreten können. Wenn keine Bedenken bestehen, die Zusammenballungen durch die Wälzkörper selbst zertrümmern zu lassen, so genügen kleinere Spaltweiten, die jedoch niemals unter die Größe des Kornes absinken dürfen.If several rolling surfaces are used, the invention should continue to do so a gap which is larger than that can be left free between the two surfaces corresponds to the largest grain size of the dust. It is understood that provided dust is present, which tends to agglomerate, this gap must be kept so large, that even the greatest agglomerations to be expected are still unhindered by him can pass through. If there are no concerns, the clumps through To let the rolling elements smash themselves, smaller gap widths are sufficient however, they must never drop below the size of the grain.

Schließlich soll darauf Bedacht genommen sein, daß unterhalb des Spaltes zwischen den Abwälzflächen ein Raum zur Aufnahme des Staubes oder ein Abweiserblech zu seiner Abfuhr vorgesehen sein soll.Finally, care should be taken to ensure that below the gap between the rolling surfaces a space for receiving the dust or a deflector plate to be provided for its removal.

Die Zeichnung stellt zwei Ausführungsbeispiele des Gegenstandes der Erfindung dar. Zwei untere Abwälzbahnen 1 und 2 gemäß der Ausführung nach Abb. 1 sind je unter einem Winkel a gegenüber der Waagerechten 3 angeordnet, der größer ist als der Schüttwinkel des Staubes.The drawing represents two embodiments of the subject matter of Invention. Two lower rolling tracks 1 and 2 according to the embodiment of FIG are each arranged at an angle a relative to the horizontal 3, which is greater is than the angle of repose of the dust.

Zwischen sich schließen diese beiden Laufbahnen einen Spalt 4 ein, dessen Breite ebenfalls größer ist als die größte übliche Staubzusammenballung. In den Laufflächen 1 und 2 ist eine Kugel 5 angeordnet, die über einen waagerechten Laufring 6 den darüber dargestellten, nicht gezeichneten Drehkörper trägt. Unterhalb des Spaltes ist ein Abweiserblech 7 angeordnet, das unter dem gleichen Winkel steht wie die beiden Laufflächen 1 und 2.These two raceways form a gap 4 between them, whose width is also greater than the largest common dust agglomeration. In the running surfaces 1 and 2, a ball 5 is arranged, which has a horizontal Race 6 carries the rotating body shown above, not shown. Below the gap is a deflector plate 7 is arranged, which is at the same angle like the two running surfaces 1 and 2.

Gemäß Abb. 2 werden die Kugeln 5 auf zwei Ringschneiden 9 geführt.According to Fig. 2, the balls 5 are guided on two cutting rings 9.
