Description

Ventilatorgehäuse für staubführende Luft oder Gase. Gehäuse von Ventilatoren, welche staubhaltige Luft oder Gase zu fördern haben, sind je nach der Beschaffenheit der in dem Fördermittel enthaltenen festen Bestandteile einem mehr oder weniger großen Verschleiß ausgesetzt. Dieser Verschleiß macht sich insbesondere bei Ventilatoren, welche unmittelbar mit einer Mahlanlage in Verbindung stehen und das erinahlene Gut zu fördern, haben, sehr unangenehm bemerkbar. Dieser Verschleiß ist darauf zurückzuführen, daß die Geschwindigkeit des Fördermittels an der Innenfläche des Ventilatorgehäuses außerordentlich groß ist. Bei den jetzt bekannten Ausführungen der Ventilatoren wurde in das Ventilatorg.ehäuse ein glattes Verschleißblech aus Stahl oder einem anderen dauerhaften Material eingebaut, welches von Zeit zu Zeit erneuert werden mußte. Diese Erneuerung hatte neben den aufzuwendenden Kosten noch den Nachteil, daß die mit .dem Ventilator verbundene Anlage während der Dauer der Reparatur stillgesetzt werden mußte.Fan housing for dust-carrying air or gases. Fan housings, which dusty air or gases have to be conveyed, depend on the nature of the solid components contained in the funding one more or less exposed to great wear and tear. This wear is particularly evident in fans, which are directly in connection with a grinding plant and the remembered Well to promote, have very uncomfortably noticeable. This wear is due to that the speed of the conveyor on the inner surface of the fan housing is extraordinarily large. With the fan designs now known a smooth wear plate made of steel or a other permanent material installed, which will be renewed from time to time had to. In addition to the costs, this renewal also had the disadvantage that the system connected to the fan is shut down for the duration of the repair had to become.

Die vorliegende Erfindung soll diese Nachteile beseitigen.The present invention aims to overcome these disadvantages.

In der Zeichnung ist in Abb. i mit a die bisher gebräuchliche Ausführung des Verschleißbleches gezeichnet. Die Erfindung beabsichtigt, diesen hohen Versdzleiß durch Einbau von entsprechenden Mitteln in das Ventilatorgehäuse aufzuheben. Diese Mittel können verschiedenartig sein und haben den Zweck, auf der Innenfläche des Ventilatorgehäuses Hemmungen hervorzurufen, wodurch die Geschwindigkeit des Fördermittels verringert und damit gleichzeitig der Verschleiß reduziert wird.In the drawing, in Fig. I with a, the design that has been used up to now is shown of the wear plate drawn. The invention intends to reduce this high wear and tear by installing appropriate means in the fan housing. These Means can be of various types and have the purpose of being applied to the inner surface of the Fan housing cause inhibitions, thereby reducing the speed of the conveyor reduced and thus the wear is reduced at the same time.

Abb.2 und 3 zeigen Ausführungsbeispiele, in welcher Weise die Widerstände an der Verschleißfläche des Ventilatorgehäuses erzeugt werden können. In Abb.2 wird ein wellenförmiger Stahlmantel eingebaut, während in Abb. 3 die beabsichtigten Widerstände durch Einbau von Winkeln, welche parallel mit der Ventilatorachse liegen, hervorgerufen werden.Fig.2 and 3 show examples of how the resistors can be generated on the wear surface of the fan housing. In Fig 2 is a wave-shaped steel jacket built in, while in Fig. 3 the intended resistances caused by the installation of angles which are parallel to the fan axis will.
