Pneumatische Fördereinrichtung zum Reinigen von BrunnenPneumatic conveying system for cleaning wells

Das Prinzip des Injektors ist bekannt (Wasser- oder Dampfstrahlpumpe). Erfindungsgemäß wird unter Nutzung dieses Prinzips eine Einrichtung zum Entfernen von Verunreinigungen oder Schwebstoffen aus Trink- oder Brauchwasserbrunnen, die sich am Boden des Brunnens angesammelt haben und sich insbesondere nach der Anwendung mechanischer Reinigungsverfahren oder von Impulsgeneratoren im Wasser befinden, als vorteilhafte Kombination dazu vorgeschlagen.The principle of the injector is known (water or steam jet pump). According to the invention, using this principle, a device for removing impurities or suspended matter from drinking or industrial water wells that have accumulated at the bottom of the well and are in the water, in particular after the application of mechanical cleaning processes or pulse generators, is proposed as an advantageous combination.

Das für den Betrieb erforderliche Druckgas (Stickstoff oder hilfsweise Druckluft) ist zum Betrieb des pneumatischen Impulsgenerators ohnehin erforderlich und kann zur Förderung des verunreinigten Wassers ebenfalls eingesetzt werden.The compressed gas required for operation (nitrogen or alternatively compressed air) is required anyway to operate the pneumatic pulse generator and can also be used to pump the contaminated water.

Die Wirkung der Fördereinrichtung setzt sich aus dem Gasdruck (Förderhöhe), der Gasmenge (Fördermenge) und dem Auftrieb der Gasblasen (Strömungsenergie) zusammen.The effect of the conveying device is made up of the gas pressure (conveying head), the gas quantity (conveying quantity) and the buoyancy of the gas bubbles (flow energy).

Die erfindungsgemäße Fördereinrichtung besteht aus dem Ansaugrohr (1) mit seitlichen Aussparungen am unteren Ende als Zuströmhilfe, dem Grundkörper (2) mit der Hauptdüse (3) und dem Lochkranz der Einströmöffnungen (4) für das Druckgas, dem Abdeckring (5) für die Druckkammer (6), dem Förderrohr (7) und der Zuführleitung (8) für das Druckgas. Am Grundkörper sind Oesen zur Aufnahme des Zugmittels zum Hinablassen der Fördereinrichtung in den Brunnen und zum Bergen desselben nach Gebrauch angebracht. Die Arbeitsweise der Fördereinrichtung wird außer durch ihre Abmessung nur durch die Eigenschaften des Druckgases (Druck, Menge) bestimmt.The conveying device according to the invention consists of the intake pipe (1) with lateral recesses at the lower end as an inflow aid, the base body (2) with the main nozzle (3) and the perforated ring of the inflow openings (4) for the compressed gas, the cover ring (5) for the pressure chamber (6), the conveying pipe (7) and the supply line (8) for the compressed gas. Eyelets are attached to the base body to accommodate the traction device for lowering the conveying device into the well and for retrieving it after use. The way the conveying device works is determined, apart from its dimensions, only by the properties of the compressed gas (pressure, quantity).

Lothar Spitzner Agricolastr. 19 0422*9 Leipzig Ansprüche : Gebrauchsmuster Pneumatische Fördereinrichtung zum Reinigen von BrunnenLothar Spitzner Agricolastr. 19 0422*9 Leipzig Claims: Utility model Pneumatic conveying device for cleaning wells 1. Einrichtung zur Reinigung von Brunnen zur Wassergewinnung auf der Basis des Injektorprinzips, dadurch gekennzeichnet, daß ein Gas, unter Druck und in ausreichender Menge einer aus dem Grundkörper (2) und dem damit verschraubten Abdeckring (5) gebildeten Kammer (6) und nachfolgend durch die kranzförmig um die Hauptdüse (3) angeordneten Einströmöffnungen (4) dem Strömungskanal gerichtet zugeführt, einen Druckunterschied zwischen dem Bereich vor und nach der Hauptdüse bewirkt, der eine Strömung herbeiführt und damit auf im Brunnen befindliche Ablagerungen und Schwebstoffe eine Sogwirkung in Richtung auf das über Tage befindliche Ende des Förderrohrs (7) ausübt.1. Device for cleaning wells for water extraction based on the injector principle, characterized in that a gas, under pressure and in sufficient quantity, is fed into a chamber (6) formed from the base body (2) and the cover ring (5) screwed to it and subsequently through the inflow openings (4) arranged in a ring around the main nozzle (3) directed to the flow channel, causes a pressure difference between the area before and after the main nozzle, which brings about a flow and thus exerts a suction effect on deposits and suspended matter in the well in the direction of the end of the conveyor pipe (7) located above ground. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß an der Ausgangsseite des Grundkörpers sich eine oder mehrere Oesen zum Befestigen eines Zugmittels befinden.Device according to claim 1, characterized in that one or more eyelets for fastening a traction means are located on the output side of the base body. 3. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Teile 1-6 der Fördereinrichtung aus polymeren Stoffen oder aus korrosionsfestem Material gefertigt sind.3. Device according to claim 1, characterized in that the parts 1-6 of the conveyor device are made of polymeric materials or of corrosion-resistant material.
