Description

Rohrkrümmer für Förderleitungen. Die Erfindung betrifft einen für pneumatische Förderanlagen bestimmten Rohrkrümmer nach Patent 398 2q.1., bei welchem die äußere Bogenwand aus elastischem Stoff, z. B. Gummi, besteht. Gegenüber der in der Patentschrift 398 241 dargestellten Ausführungsform ist gemäß der vorliegenden Erfindung die elastische Platte vorzugsweise als ebene Platte ausgeführt, um die elastische Wirkung zu begünstigen.Elbow pipe for delivery lines. The invention relates to a for pneumatic conveying systems specific pipe bends according to patent 398 2q.1., in which the outer arch wall made of elastic fabric, e.g. B. rubber. Compared to the The embodiment illustrated in Patent 398,241 is in accordance with the present Invention, the elastic plate is preferably designed as a flat plate to the to favor elastic action.

Da bei pneumatischen Druckförderanlagen der Druck in solchen Krümmern oft recht erheblich ist, müßte die Gummiplatte, um diesem Druck standzuhalten, eine erhebliche Stärke besitzen oder mit festen Einlagen versehen sein. Hierdurch würde sie aber wieder ihre elastische Eigenschaft einbüßen.As in pneumatic pressure conveying systems, the pressure in such bends is often quite considerable, the rubber sheet would have to be a have considerable strength or be provided with solid inserts. This would but they again lose their elastic properties.

Die vorliegende, auf der Zeichnung in zwei zueinander senkrechten Schnitten in Abb. i und Abb.2 in einer beispielsweisen Ausführungsform dargestellte Erfindung beseitigt diesen Übelstand dadurch, daß über die Gummiplatte 2 des Krümmers i eine feste Kappe 3 an dem Krümmer i befestigt ist. Diese Kappe 3 steht mit dem unteren Teil q. des Krümmers i derart durch einen Hohlraum 5 in Verbindung, daß ständig ein Druckausgleich zwischen der inneren und äußeren Seite der Gummiplatte stattfindet. Hierdurch wird die Platte von dem in der Rohrleitung herrschenden Druck vollständig entlastet und kann verhältnismäßig dünn gehalten werden, weil sie nur die Stöße des Materialstromes aufzunehmen hat.The present one, on the drawing in two mutually perpendicular Sections in Fig. I and Fig.2 shown in an exemplary embodiment Invention eliminates this drawback in that over the rubber plate 2 of the manifold i a fixed cap 3 is attached to the manifold i. This cap 3 stands with the lower part q. of the manifold i in such a way through a cavity 5 in connection that constant pressure equalization between the inner and outer side of the rubber plate takes place. As a result, the plate is relieved of the pressure prevailing in the pipeline completely relieved and can be kept relatively thin because they only has to absorb the shocks of the material flow.
