Description

DEUTSCHESGERMAN

Die Erfindung betrifft eine Spritzdüse für Mörtel od. dgl. mit einem ringförmig um das Ende des Mörtelzuführungsrohres angeordneten Druckraum für die Einführung von Druckluft, Druckflüssigkeit od. dgl. in den aus dem Mörtelzuführungsrohr austretenden Materialstrang sowie mit einem in Verlängerung des Mörtelzuführungsrohres angeordneten Strahlrohr, das etwa in der Mitte einen verengten Querschnitt aufweist.The invention relates to a spray nozzle for mortar od. The like. With a ring around the end of the Mortar supply pipe arranged pressure chamber for the introduction of compressed air, hydraulic fluid od. The like. In the material strand emerging from the mortar feed pipe and with an extension of the mortar feed pipe arranged jet pipe, which narrowed approximately in the middle Has cross section.

Die Erfindung besteht darin, daß der verengte Querschnitt des Strahlrohres kleiner ist als der Austrittsquerschnitt des Mörtelzuführungsrohres.The invention consists in that the narrowed cross section of the jet pipe is smaller than the exit cross section of the mortar feed pipe.

Eine derartige Strahlrohrform schafft beim Spritzen eine Zone hohen Druckes, die besonders wirksam ist. Der kegelstumpfförmig aus dem Druckraum austretende Gasstrang od. dgl., der am Umfang des aus dem Mörtelzuführungsrohr austretenden Materialstranges mündet, drückt in das Innere dieses Materialstranges hinein und bewirkt ein energisches Verrühren des Materials.Such a nozzle shape creates a zone of high pressure during spraying, which is particularly effective. The frustoconical emerging from the pressure chamber od The material strand emerging from the mortar feed pipe opens, pushes into the interior of this material strand into it and causes vigorous stirring of the material.

Ein weiteres Merkmal der Erfindung besteht darin, daß der Eintrittsquerschnitt des Strahlrohres etwa dem Aüstrittsquerschnitt des Mörtelzuführungsrohres entspricht. Dadurch wird erreicht, daß nur eine sehr geringe Menge Druckluft, Druckflüssigkeit od. dgl. für das Verrühren des aus dem Mörtelzuführungsrohr austretenden Materials erforderlich ist.Another feature of the invention is that the inlet cross section of the jet pipe approximately corresponds to the exit cross-section of the mortar feed pipe. This ensures that only one very small amount of compressed air, hydraulic fluid or the like for stirring the from the mortar feed pipe escaping material is required.

Es ist ferner zweckmäßig, wenn der Eintritts- und Austrittsquerschnitt des Strahlrohres gleich groß sind. Durch eine solche Ausbildung wird am Düsenaustritt ein mit dem Druckmittel ausgezeichnet vermischter Materialstrang erhalten, der den gleichen Querschnitt hat wie der aus dem Mörtelzuführungsrohr austretende Strang. Der aus dem Strahlrohr austretende vermischte Material strang hat aber eine erheblich größere Geschwindigkeit.It is also useful if the inlet and outlet cross-sections of the jet pipe are of the same size. With such a design, an excellent mixture with the pressure medium is achieved at the nozzle outlet Obtained strand of material which has the same cross-section as that emerging from the mortar feed pipe Strand. However, the mixed strand of material emerging from the jet pipe has a considerable amount greater speed.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Spritzdüse wird gebildet aus einem Mörtelzuführungsrohr 1 und einem Strahlrohr 10. Der zylindrische Endansatz 2 des Mörtelzuführungsrohres 1 ist von einem als Drehkörper ausgebildeten Ringstück 3 umgeben, das mit dem Ansatz 2 einen ringförmigen Druckraum 4 einschließt. Diesem Druckraum 4 wird über eine Leitung 5 ein Druckmittel, z. B. Druckluft, Druckflüssigkeit od. dgl., zugeführt. Das Ringstück 3 hat eine kegelstumpfförmig zulaufende Wandung 6, während das Ende des Ansatzes 2 eine kegelstumpfförmige Abschrägung 8 aufweist. Dadurch ergibt sich ein ringförmiger Spalt 7, aus dem das Druckmittel in das Strahlrohr austritt.The spray nozzle is formed from a mortar feed pipe 1 and a jet pipe 10. The cylindrical end extension 2 of the mortar feed pipe 1 is surrounded by an annular piece 3 designed as a rotating body, which encloses an annular pressure chamber 4 with the extension 2. This pressure chamber 4 is a pressure medium, z. B. compressed air, hydraulic fluid or the like., Supplied. The ring piece 3 has a frustoconical wall 6, while the end of the extension 2 has a frustoconical bevel 8. This results in an annular gap 7 from which the pressure medium exits into the jet pipe.

Die Stirnseite 9 des ringförmigen Spaltes 7 hat im wesentlichen denselben Durchmesser wie die Austrittsöffnung des Ansatzes 2. The end face 9 of the annular gap 7 has essentially the same diameter as the outlet opening of the extension 2.

Auf das vordere Ende des Ringstückes 3 ist das Strahlrohr 10 aufgeschraubt, dessen lichte Weite eine Verjüngung 11, eine Einschnürung 12 und eine Erweiterung 13 aufweist.On the front end of the ring piece 3, the jet pipe 10 is screwed, the clear width of a Taper 11, a constriction 12 and an enlargement 13.

Das Spritzmaterial bewegt sich in Richtung des Pfeiles f, das Treibmittel strömt in Richtung des Pfeiles g, und das Gemisch tritt bei 14 aus dem Strahlrohr 10 aus.The spray material moves in the direction of arrow f, the propellant flows in the direction of arrow g, and the mixture emerges from the jet pipe 10 at 14.

Die Düse arbeitet folgendermaßen: Der Materialstrang wird bei seinem Austritt aus dem Ansatz 2 am Umfang von einem starken Druckmittelstrahl umspült und tangential in Austrittsrichtung beaufschlagt, wobei durch die Saugwirkung des Druckmittelstrahls eine Beschleunigung des Materialstranges erfolgt. Infolge des an der Einschnürung 12 herrschenden hohen Drucks ergibt sich in der Zone 11 eine heftige Durchwirbelung und somit eine ausgezeichnete Vermengung des Spritzmaterials mit dem Druckmittel. Das Gemisch wird durch die Zone 13 zur Strahlrohrmündung 14 herausgestoßen.The nozzle works as follows: When the strand of material emerges from the attachment 2 Washed around the circumference by a strong jet of pressure medium and applied tangentially in the exit direction, whereby the suction effect of the pressure medium jet accelerates the material strand he follows. The high pressure prevailing at the constriction 12 results in the zone 11 a violent turbulence and thus an excellent mixing of the spray material with the Pressure medium. The mixture is expelled through the zone 13 to the nozzle mouth 14.
