Abstract

A cylinder contains a pressure chamber (1) in its top part, connected at its bottom end to a work chamber (3) via a pressure valve (2). A piston (4) housed inside the pressure chamber is supported by elastic material at its bottom end, this material being compressed when the counter-pressure chamber around it is pressurized. A stopper is used to seal the bottom of the cylinder, which contains an opening for draining it, in additional to exit openings (5) normally sealed by the piston when in its upper (resting) position. An Independent claim is also included for a method of cleaning spring wells etc. using this equipment.

Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Regenerierung und Reinigung von Brunnen, Rohrleitungen und Behältern mittels Impulsen.The invention relates to a device and a method for regeneration and cleaning of wells, pipes and containers by means of pulses.

Die Erzeugung von Impulsen in hydraulischer Umgebung der Impulsquelle ist bekannt und wird beispielsweise für meßtechnische Zwecke genutzt (Sonargeräte).The generation of pulses in the hydraulic environment of the pulse source is known and is used, for example, for measuring purposes (sonar devices).

Die Impulsausbreitung geschieht im Idealfall kugelförmig um die Quelle nach bekannten Gesetzmäßigkeiten der Energieausbreitung oder richtungsgebunden.Ideally, the pulse propagation takes place spherically around the source according to known ones Laws of energy spread or directional.

Nachteilig bei den bekannten Verfahren ist, daß das Medium als Energieträger vorwiegend kraft seines Volumens wirkt und damit die in den Brunnen einzubringende Menge ver­ gleichsweise groß ist und bei Verwendung von Gas als Medium ein zusätzlicher Entgasungsaufwand nötig wird.A disadvantage of the known methods is that the medium is predominantly used as an energy source by virtue of its volume and thus the amount to be introduced into the well is equally large and an additional one when using gas as a medium Degassing effort is necessary.

Die Erfindung stellt sich sich die Aufgabe, eine Vorrichtung zu schaffen, welche gründliche­ re Reinigungsvorgänge erzielt und konstruktiv einfach gehalten ist.The object of the invention is to provide a device which is thorough re cleaning operations achieved and is structurally simple.

Diese Aufgabe wird durch eine in den Patentansprüchen 1-7 beschriebene Vorrichtung und das Verfahren gelöst.This object is achieved by a device described in claims 1-7 and solved the procedure.

Erfindungsgemäß wird vorgeschlagen, mittels plötzlicher Entspannung komprimierter Gase oder unter Druck stehender Flüssigkeiten gewonnene energiereiche Impulse entsprechend des Standes der Technik zur Lockerung und zum Transport gelockerter Ablagerungen (Mangan-, Eisen- und Kalk-Verbindungen und deren Gemische) im Kiesumfeld und in den Schlitzen des Filterrohres von Brunnen einzusetzen, wobei die Impulsenergie und die Zufuhr des expandierenden Mediums zunächst auf das im Brunnen und seinem Umfeld anstehende Wasser einwirkt und es teilweise zurückdrängt und danach in Umkehr des Vorgangs ein Gemisch aus Wasser, Verunreinigungen und Medium in das Brunnenrohr zurückfließt, zunächst bis zum Druckausgleich und weiter bei nachfolgendem Pumpvorgang.According to the invention, it is proposed to use compressed gases by means of sudden relaxation or energetic impulses obtained under pressure from liquids the prior art for loosening and transporting loosened deposits (Manganese, iron and lime compounds and their mixtures) in the gravel area and in the Use slots of the filter tube of wells, the pulse energy and the Feeding the expanding medium first to that in the well and its surroundings existing water acts and partially pushes it back and then reversing the Process a mixture of water, contaminants and medium into the well pipe flows back, first up to the pressure equalization and further with the following one Pumping.

Dieser sollte bei Verwendung eines gasförmigen Mediums erst dann folgen, wenn ein wesentlicher Teil des Gases im Brunnenrohr aufgestiegen ist.When using a gaseous medium, this should only follow when a substantial part of the gas has risen in the well pipe.

Die erfindungsgemäße Vorrichtung besteht vorzugsweise aus einem Zylinder mit einer in seinem oberen Teil angeordneten Druckkammer, welche an ihrem unteren Ende vorzugs­ weise mittels eines Druckventils mit einer Arbeitskammer verbunden ist. The device according to the invention preferably consists of a cylinder with an in its upper part arranged pressure chamber, which is preferred at its lower end is connected to a working chamber by means of a pressure valve.  

In dieser Arbeitskammer ist ein Kolben angeordnet.A piston is arranged in this working chamber.

Dieser Kolben ist nach unten auf beziehungsweise in einer elastischen Masse gelagert, welche bei Belastung in der sie umfassenden Gegendruckkammer komprimiert wird. Der die erfindungsgemäße Vorrichtung bildende Zylinder ist an seiner Unterseite mit einem Stopfen verschlossen und weist eine Öffnung zum Entleeren der Vorrichtung auf.This piston is supported on or in an elastic mass, which is compressed when loaded in the back pressure chamber that surrounds it. The cylinder forming the device according to the invention is provided with a Plug closed and has an opening for emptying the device.

In der Außenwand des Zylinders sind Ausströmöffnungen so angeordnet, daß diese durch den Kolben verschlossen werden, wenn sich dieser in seiner oberen, der Ruheposition gleichkommenden Stellung befindet.Outflow openings are arranged in the outer wall of the cylinder so that they pass through the piston is closed when it is in its upper, rest position equals position.

An seinem oberen Ende ist der Zylinder mit der volumenveränderlichen Druckkammer ver­ bunden.At its upper end, the cylinder with the variable-volume pressure chamber is ver bound.

Die Wirkungsweise der erfindungsgemäßen Vorrichtung soll anhand eines Ausführungs­ beispieles und einer Abbildung erläutert werden.The operation of the device according to the invention should be based on an embodiment example and an illustration.

Die mit der Vorrichtung verbundene volumenveränderliche Kammer, welche eine Schlauchkonstruktion sein kann, wird mit einem Druck durch ein flüssiges oder gasförmi­ ges Medium beauflagt.The variable volume chamber connected to the device, which a Hose construction can be with a pressure through a liquid or gaseous entire medium.

Dadurch wird auch in Druckkammer 1 Druck aufgebaut.This also builds up pressure in the pressure chamber 1 .

Dieser Druck öffnet bei erreichen einer bestimmten Größe plötzlich das Ventil 2 zwischen Druckkammer 1 und Arbeitskammer 3 und das Medium strömt in die Arbeitskammer 3 ein, bewegt den Kolben 4 nach unten und strömt durch die durch die Kolbenbewegung geöffne­ ten Ausströmöffnung 5 explosionsartig nach außen.When a certain size is reached, this pressure suddenly opens the valve 2 between the pressure chamber 1 and the working chamber 3 and the medium flows into the working chamber 3 , moves the piston 4 downwards and flows explosively through the outflow opening 5 opened by the piston movement.

Durch diesen plötzlichen Druckverlust bewegt die komprimierte Rückstellmasse 6 den Kolben 4 wieder in seine obere Position und verschließt dabei das Ventil 2 wieder. Der in der Folgezeit in der volumenveränderlichen Kammer 7 und der Druckkammer i auf­ gebaute Druck entspannt sich wieder über das Ventil 2 in die Arbeitskammer 3 und der Prozess beginnt von vorn.Due to this sudden pressure loss, the compressed restoring mass 6 moves the piston 4 back into its upper position and closes the valve 2 again. The pressure subsequently built up in the volume-variable chamber 7 and the pressure chamber i relaxes again via the valve 2 into the working chamber 3 and the process begins again.
