Description
<Desc/Clms Page number 1>
Einrichtung zum pneumatischen Fördern körniger oder schwerfliessender Massen
EMI1.1
<Desc/Clms Page number 2>
In den Zeichnungen ist ein Ausführungsbeispiel der erfindungsgemässen Ausbildung dargestellt.
Fig. 1 zeigt in Perspektive und teilweise im Schnitt die Einrichtung nach der Erfindung ; Fig. 2 zeigt einen Schnitt nach der Linie II-II in Fig. l ; Fig. 3 zeigt in grösserem Massstab einen Schnitt durch die Achse einer Düse ; Fig. 4 zeigt einen Schnitt nach der Linie IV-IV in Fig. 3.
Die Einrichtung besteht aus einem Druckgefäss mit einem konischen Teil-l-, der von einem Gestell --2-- getragen wird, und im unteren Ende mit einer Rohrleitung --3-- verbunden ist. Der Teil-l-geht oben in einen zylindrischen Teil--4-- über, der mit einem gewölbten Teil-5und mit einem zentralen die Einfüllöffnung darstellenden Trichterteil-6-versehen ist.
Der Trichter --6-- ist durch einen konischen Schliessteil-7-verschliessbar, welcher Teil - durch Luftdrucksteigerung in dem Gefäss dicht an die untere Trichteröffnung gedrückt wird, nachdem der Teil --7-- erst mittels eines Handgriffes --8-- gehoben worden ist. Die Druckluft wird in das Gefäss, von einem in den Zeichnungen nicht gezeigten Kompressor, durch vier in verschiedenen Höhen im Gefässwandteil --1-- angeordnete Düsen --9,10,11 und 12-eingebracht, wobei diese Düsen je um 900 zueinander versetzt angeordnet sind.
Die Düsen sind schräg nach unten sowohl zur Gefässachse als auch zur Tangente im Einführungspunkt der Gefässwand gerichtet.
Die Düsen bestehen wie in Fig. 3 gezeigt, aus einem Düsenrohr-II-, dessen Ende ein Stück in das Gefäss hineinragt und schräg zur Düsenachse vom Gefässinneren zur Gefässwand verläuft. Ein Stück
EMI2.1
Dadurch wird dem Druckluftstrom eine Schraubenbewegung gegeben, welche den Druckluftstrom auf den Beton konzentriert, und diesen in schraubenförmige Bewegung versetzt.
Um diese Konzentration der Druckluft möglichst am Gefässrand zu halten, ist das Düsenende schräg zur Düsenachse vom Gefässinneren nach der Gefässwand so abgeschnitten, dass der kürzere Teil des Düsenendes am Durchtrittspunkt der Düse in der Gefässwand liegt und der längere Teil-13abschirmend gegen den Beton gerichtet ist.

Device for the pneumatic conveying of granular or difficult-to-flow materials
EMI1.1
<Desc / Clms Page number 2>
In the drawings, an embodiment of the inventive design is shown.
Fig. 1 shows in perspective and partially in section the device according to the invention; Fig. 2 shows a section along the line II-II in Fig. 1; 3 shows, on a larger scale, a section through the axis of a nozzle; FIG. 4 shows a section along the line IV-IV in FIG. 3.
The device consists of a pressure vessel with a conical part -l-, which is carried by a frame --2-- and connected at the lower end to a pipe --3--. The part-1-merges at the top into a cylindrical part-4-which is provided with a curved part-5 and with a central funnel part-6, which represents the filling opening.
The funnel --6-- can be closed by a conical closing part -7-, which part - is pressed tightly against the lower funnel opening by increasing the air pressure in the vessel, after the part --7-- only by means of a handle --8-- has been lifted. The compressed air is brought into the vessel by a compressor not shown in the drawings through four nozzles - 9, 10, 11 and 12 - arranged at different heights in the vessel wall part - 1 -, these nozzles being offset by 900 to one another are arranged.
The nozzles are directed obliquely downwards both to the vessel axis and to the tangent at the point of entry of the vessel wall.
As shown in FIG. 3, the nozzles consist of a nozzle tube-II-, the end of which projects a little into the vessel and runs obliquely to the nozzle axis from the inside of the vessel to the vessel wall. One piece
EMI2.1
This gives the compressed air flow a helical movement which concentrates the compressed air flow on the concrete and sets it in a helical movement.
In order to keep this concentration of the compressed air as close as possible to the edge of the vessel, the nozzle end is cut off at an angle to the nozzle axis from the inside of the vessel to the vessel wall so that the shorter part of the nozzle end is at the point where the nozzle passes through the vessel wall and the longer part is directed against the concrete in a shielding manner .
