Description

Vorrichtung zum Verringern der Austrittsgeschwindigkeit eines mittels Druclduft geförderten Beton- oder Igörtelstrahles. Die Erfindung betrifft eine Vorrichtung zum Verringern der Austrittsgeschwindigkeit eines mittels Druckluft geförderten Beton- oder Mörtelstrahles, bei -welchem das Austrittsende der Rohrleitung an ein Gehäuse von größerem Querschnitt angeschlossen ist.Device for reducing the exit speed of a means Concrete or mortar spray conveyed by compressed air. The invention relates to a device to reduce the exit speed of a conveyed by means of compressed air Concrete or mortar jet, with -which the outlet end of the pipeline to a Housing of larger cross-section is connected.

Das Neue besteht darin, daß die der Rohraustrittsöffnung gegenüberliegende Wand des Gehäuses aus nachgiebigem Stoff besteht. Diese Wand soll die Kraft des mit großer Geschwindigkeit austretenden Betonstromes teilweise oder ganz vernichten, so daß der Betonstroin gut mit Wasser vermischt als ein gleichmäßiger Strahl von, niedriger Geschwindigkeit an die Gebrauchsstelle gelangt.The novelty is that the one opposite the pipe outlet opening Wall of the housing is made of flexible fabric. This wall is supposed to the force of the concrete stream escaping at high speed partially or destroy completely, so that the concrete stroin is well mixed with water as a uniform one Jet reaches the point of use at low speed.

In der Zeichnung ist die Vorrichtung beispielsweise in einer Ausführung dargestellt. Es zeigen: Abb. i das an die Rohrleitung angeschlossene düsenartige Gehäuse im senkrechten Schnitt, Abb. 2 eine Draufsicht auf die nachgiebige Wand, Abb. 3 einen Schnitt nach Linie A-B der Abb. i.In the drawing, the device is shown in one embodiment, for example. They show: Fig. I the nozzle-like housing connected to the pipeline in vertical section, Fig. 2 a plan view of the flexible wall, Fig. 3 a section along line AB in Fig. I.

Mit a ist dag düsenartige Gehäuse, dessen Querschnitt größer ist als der der Rohrleitung, bezeichnet. In dessen oberen Teil mündet die Förderleitung b ein. Gegenüber dieser Einmündungsöffnung ist in der Gehäusewand eine Platte oder Fläche c aus nachgiebigem Stoff, z. B. Gummi, angeordnet. Diese Platte c ist mit Schrauben in der ausgesparten Gehäusewand befestigt, um so eine leichte Auswechselung oder Ersatz derselben zu ermöglichen. Das nach unten hin sich verengende Gehäuse al- ist in d offen, um das geförderte Gut auf die Verwendungsstelle herausfallen zu lassen.With a is dag nozzle-like housing, the cross section of which is larger than that of the pipeline. The delivery line b opens into its upper part. Opposite this confluence opening is a plate or surface c made of flexible material, for. B. rubber, arranged. This plate c is fastened with screws in the recessed housing wall so as to enable it to be easily exchanged or replaced. The downwardly narrowing housing al- is open in d in order to allow the conveyed goods to fall out onto the point of use.

Die Wirkungsweise ist folgende: Der durch den Stutzen b mit großer Geschwindigkeit in das Gehäuse eintretende Betonstrahl trifft auf die nachgiebige Gummiplatte c und bringt diese nach außen hin zum Ausweichen. Würde der Betonstrahl augenblicklich- zu fließen aufhören, so würden die an die Plätt(2 geschleuderten Teile durch die Nachgiebigkeit des Gummis mit derselben Geschwindigkeit zurückgeschleudert werden. Da der Betonstrahl aber ununterbrochen weiterfließt, so schwingt die Platte c nur in ganz geringem Maße aus, da ein vollständiges 2urückschwi . ngen der Platte nach innen stets durch einen neuen Aufprall frischen Baustoffes verhindert wird. Hierbei fällt nun der feinere Baustoff, ohne eine nennenswerte Kraft zu besitzen, sofort herunter, während gröbere Teile, namentlich Steine, zwar noch eine gewisse Kraft besitzen, diese aber durch den mehrfachen Anprall an die Wandungen des Gehäuses ebenfalls einbüßen. Der Baustoff tritt also bei dieser Vorrichtung sowohl mit Wasser gut vermischt als auch in verminderter Geschwindigkeit aus dem düsenartigen Gehäuse aus.The mode of operation is as follows: The concrete jet entering the housing through the nozzle b at high speed hits the flexible rubber plate c and causes it to evade outwards. If the concrete jet were to stop flowing immediately, the parts thrown against the plate (2) would be thrown back at the same speed due to the elasticity of the rubber. But since the concrete jet continues to flow uninterrupted, the plate c swings out only to a very small extent, da is a complete 2urückschwi. hang the plate after always inside fresh with a new impact building material prevented. Here, now falls the finer building materials, without having a significant force, immediately shut, still have a certain power while coarser parts, including stones, However, these are also lost due to the multiple impacts on the walls of the housing.
