Pneumatic discharge device for raising sewage or effluent from underground installation, has collection vessel with vertical pipe leading to inlet and stand pipe leading to exit

The effluent inlet opening (8) is located in the cover (9) for the effluent collection vessel (6), and on the inside of the cover this opening is surrouned by a vertical pipe (10) forming an airtight seal with the cover. The bottom end (11) of the vertical pipe is located above the bottom of the vessel. Effluent is forced out through an exit opening close to the bottom of the vessel, this opening being formed by the bottom end (15) of a stand pipe (16) leading into the effluent exit pipe (17). The stand pipe extends to a height above the inlet opening in the vessel cover, whilst its bottom end is essentially level with the bottom end of the vertical pipe. Effluent in the collection vessel (6) is forced out via an exit pipe by closing the pipe (13) for removing air from the vessel and closing the valve in the effluent inlet pipe (7) once the effluent level inside the vessel has reached a maximum height, and then supplying compressed air to the vessel in order to force effluent out through an exit opening close to the vessel floor and into the exit pipe. Die Erfindung betrifft eine pneumatisch zu betreibende Abwasserhebeanlage für Haus- und Grundstücksabwasser, und es wird vorgeschlagen, in den Sammelbehälter der Anlage einen schwimmkugel-gesteuerten Zulauf in Kombination mit einem Vertikalrohr und in Kombination mit einem Steigrohr für den druckrohrseitigen Abgang des Abwassers anzuordnen, wodurch die Anlage vollautomatisch ohne fremdgesteuerte Absperrorgane arbeitet.
