Description
Verfahren zur Verminderung des Verschleißes der Förderrohrleitungen pneumatischer oder hydraulischer Förderanlagen Die Erfindung betrifft eine weitere Ausbildung des Gegenstandes des Patentes 584 85z, bei dem in Rohrleitungen oder Rohrkrümmern Düsen angeordnet sind, die einen zusätzlichen Preßluft- oder Prcßwasserstrom zwischen Rohrwand und Fördergutstrom einzuführen gestatten.Process for reducing the wear and tear on the delivery pipelines pneumatic or hydraulic conveyor systems The invention relates to another Formation of the subject matter of patent 584 85z, in which in pipelines or Pipe elbow nozzles are arranged, which an additional compressed air or Prcßwasserstrom Allow it to be inserted between the pipe wall and the flow of material to be conveyed.
Bei dem Hauptpatent wird das zusätzliche Preßmittel besonderen Preßluft- oder Preßwasserleitungen entnommen. Gemäß der vorliegenden Erfindung wild der zusätzliche Preßluft- oder Preßwasserstrom aus der Fördergutleitung vor der gefährdeten Rohrstelle abgezweigt und dadurch die Strömungsenergie vermindert, worauf durch Wiedereinführung des abgezweigten Preßstromes an der gefährdeten Stelle die Bildung des Polsters erfolgt. Zu diesem Zweck wird die Förderleitung mit Rohranschlüssen an. einer Stelle versehen, an der der statische Druck noch höher ist als im Querschnitt der gefährdeten Rohrstelle. Der abgezweigte Preßstrom wird durch eine Hilfsleitung den Düsen zugeführt. Zur Erhöhung des statischen Druckes kann der Querschnitt der Förderleitung an der Entnahmestelle vergrößert werden.In the main patent, the additional pressing means is special compressed air or compressed water lines removed. According to the present invention wildly the additional Compressed air or compressed water flow from the conveyed material line in front of the endangered pipe point branched off and thereby reduced the flow energy, followed by reintroduction of the branched off pressure flow at the endangered point the formation of the cushion he follows. For this purpose, the delivery line is connected to pipe connections. one place at which the static pressure is even higher than in the cross-section of the endangered Pipe point. The branched off press stream is fed to the nozzles through an auxiliary line. To increase the static pressure, the cross-section of the delivery line on the Extraction point are enlarged.
Hierdurch wird einmal erreicht, daß die kinetische Energie des Fördergutstromes vermindert und an der gefährdeten Rohrstelle selbst schon durch die Herabsetzung dEr Fördergeschwindigkeit die Verschleißgefahr bedeutend verringert wird. Zum andern wird auch an Preßluft oder Preßwasser gespart und die Verwendung einer besonderen Rohrleitung für das Preßmittel überflüssig gemacht. Der Erfindungsgegenstand ist in den Abbildungen beispielsweise dargestellt, und zwar zeigen Abb. z und 2 eine Ansicht und einen Grundriß der Rohrleitung; Abb. 3 und q besondere Ausbildungsformen der Preßmittelentnahmestelle.This once ensures that the kinetic energy of the flow of conveyed material reduced and at the endangered pipe point itself already through the reduction The conveyor speed significantly reduces the risk of wear. To change is also saved on compressed air or compressed water and the use of a special one Pipeline for the pressing means made superfluous. The subject of the invention is For example, shown in the figures, namely Fig. Z and 2 show a View and plan of the pipeline; Fig. 3 and q special forms of training the press release point.
Bei den Ausführungsförmen nach den Abb. z und 2 wird der Preßstrom unmittelbar der Rohrleitung entnommen und an den gefährdeten Stellen, z. B. an dem nachfolgenden Krümmer, gemäß dem Hauptpatent wieder zugeführt. Gemäß den Abb. 3 und q. ist an der Anzapfstelle der Rohrquerschnitt vergrößert, wodurch infolge der Erhöhung des statischen Druckes auch eine Drucksteigerung des Preßstromes erreicht wird, die für die Bildung des Polsters vorteilhaft ist.In the embodiments according to Figs. Z and 2, the press flow taken directly from the pipeline and at the endangered points, e.g. B. on that subsequent manifold, supplied again according to the main patent. According to Fig. 3 and q. the pipe cross-section is enlarged at the tapping point, which as a result of the An increase in the static pressure also increases the pressure of the press flow which is advantageous for the formation of the cushion.
