Einrichtung zum pneumatischen Fördern breiiger oder plastischer Massen, vorzugsweise Beton Zusatz zur Patentanmeldung Sch17331XI/81e (Auslegeschrift 1 001 185) Die Hauptpatentanmeldung betrifft eine Einrichtung zum pneumatischen Fördern breiiger oder plastischer Massen, vorzugsweise Beton, aus einem Druckgefäß mittels Druckluft durch eine Rohrleitung zu der Verbrauchsstelle. Sein Gegenstand ist gemäß Anspruch 2 dadurch gekennzeichnet, daß im oberen Teil des Druckgefäßes an sich bekannte Drucklufteinlässe vorgesehen sind. Eine weitere Verbesserung der Einrichtung nach der Hauptpatentamneldung wird erfindungsgemäß dadurch erreicht, daß die Drucklufteinlässe als Düsen ausgebildet sind, die im Innern des Druckgefäßes angeordnet, in einem gewissen Abstand von dem größten Druckgefäßdurchmesser entfernt vorgesehen und im Wechsel tangential und vertikal gerichtet sind, wobei die Druckluft die Fördergutreste von der Druckgefäßinnenwand abschält.Equipment for the pneumatic conveying of pulpy or plastic masses, preferably concrete addendum to patent application Sch17331XI / 81e (Auslegeschrift 1 001 185) The main patent application relates to a device for pneumatic conveying pulpy or plastic masses, preferably concrete, from a pressure vessel by means of Compressed air through a pipe to the point of use. Its subject is in accordance Claim 2 characterized in that known per se in the upper part of the pressure vessel Compressed air inlets are provided. Another improvement to the facility after the main patent application is achieved according to the invention in that the compressed air inlets are designed as nozzles, which are arranged in the interior of the pressure vessel, in one Provided a certain distance away from the largest pressure vessel diameter and in the Alternation tangentially and vertically are directed, with the compressed air removing the remains of the conveyed material peeled off the inner wall of the pressure vessel. Es ist jedoch schon eine Behälter-Fördereinrichtung für Beton bekannt, bei der der Beton aus dem Behälter in die Rohrleitung mittels Druckluft gefördert wird und bei der im unteren konischen Behälterteil tangential gerichtete Düsen angeordnet sind. Die durch die Düsen zugeführte Druckluft schält die Betonreste von der Behälterwand ab und unterstützt somit die Betonförderung. However, a container conveyor for concrete is already known, in which the concrete is conveyed from the container into the pipeline by means of compressed air is and arranged in the lower conical container part tangentially directed nozzles are. The compressed air supplied through the nozzles peels the concrete residue from the container wall and thus supports the concrete delivery. Weiterhin ist es bei pneumatischen Fördereinrichtungen bereits bekannt, die Düsen zur Druckluftzufuhr im oberen Teil des Behälters anzuordnen. Furthermore, it is already known in pneumatic conveying devices to arrange the nozzles for the supply of compressed air in the upper part of the tank. In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Ausbildung dargestellt. In the drawing is an embodiment of the invention Training shown. Oberhalb des Druckgefäßes 2 befindet sich eine Ringleitung 45, der von der Leitung 1 aus Druckluft zugeführt wird, wobei die Druckluft im Anschluß an die Ringleitung durch an diese angeschlossene Düsen 44 in das Innere des Druckgefäßes geblasen wird. Die Düsen sind in einem gewissen Abstand von dem größten Druckgefäßdurchmesser so angeordnet, daß die gerichteten Luftstrahlen die Fördergutreste von der Druckgefäßinnenwand abgeschält werden. Above the pressure vessel 2 there is a ring line 45, the is supplied from the line 1 from compressed air, the compressed air in the connection to the ring line through nozzles 44 connected to it into the interior of the pressure vessel is blown. The nozzles are at a certain distance from the largest pressure vessel diameter arranged so that the directed air jets remove the remains of the conveyed goods from the inner wall of the pressure vessel be peeled off. Für den Gegenstand dieser Zusatzpatentanrneidung (Zusatzpatent) wird nur Schutz in Verbindung mit dem Gegenstand der Hauptpatentanmeldung (Hauptpatent) begehrt. For the subject of this additional patent application (additional patent) only protection in connection with the subject of the main patent application (main patent) desired. PATENTANSPRUCFT Einrichtung zum pneumatischen Fördern breiiger oder plastischer Massen, vorzugsweise Beton, aus einem Druckgefäß mittels Druckluft durch eine Rohrleitung zu der Verbrauchsstelle, bei der im oberen Teil des Druckgefäßes an sich bekannte Drucklufteinlässe vorgesehen sind, nach Anspruch 2 der Patentanmeldung Sch 17331 XI/ 81 e, dadurch gekennzeichnet, daß die Drucklufteinlässe als Düsen (44) ausgebildet sind, die im Innern des Druckgefäßes (2) angeordnet, in einem gewissen Abstand von dem größten Druckgefäßdurchmesser entfernt vorgesehen und im Wechsel tangential und vertikal gerichtet sind, wobei die Druckluft die Fördergutreste von der Druckgefäßinnenwand abschält. PATENT CLAIMED Device for the pneumatic conveying of pulpy or plastic mass, preferably concrete, from a pressure vessel by means of compressed air a pipeline to the point of use in the upper part of the pressure vessel known compressed air inlets are provided according to claim 2 of the patent application Sch 17331 XI / 81 e, characterized in that the compressed air inlets are used as nozzles (44) are formed, which are arranged in the interior of the pressure vessel (2), in a certain way Distance from the largest pressure vessel diameter provided and alternately are directed tangentially and vertically, whereby the compressed air removes the remains of the conveyed material the inner wall of the pressure vessel peels off.
