Description

Die Erfindung betrifft eine Vorrichtung zur Rohrreinigung u. a. mittels bewegter Feststoff-Flüssigkeits-Gemische. Sie ist besonders vorteilhaft anwendbar bei der Reinigung von Pipeline-Systemen.The invention relates to a device for pipe cleaning and. a. by means of agitated solid-liquid mixtures. It is particularly advantageous applicable for cleaning pipeline systems.

Es sind zahlreiche Lösungen bekannt, die auf der Durchspülung von Rohren zu Reinigungszwecken basieren. In der Regel werden hierzu chemisch aktive Reinigungslösungen, Druckwasser, Wasser-Luft- oder Wasser-Feststoff-Gemische verwendet. Die Medien werden i. a. über verfahrbare Spülköpfe in das zu reinigende Rohr gebracht und durchströmen das Rohr ohne räumliche Begrenzung in Längsrichtung. Der hierzu erforderliche Energie- und Medienaufwand ist im Verhältnis zum erzielten Reinigungseffekt gewöhnlich unverhältnismäßig hoch. Zudem ist der Pumpenverschleiß sehr hoch.Numerous solutions are known to be used for flushing pipes Cleaning purposes. As a rule, this becomes chemically active Cleaning solutions, pressurized water, water-air or water-solid mixtures used. The media will i. a. via movable flushing heads in the brought cleaning pipe and flow through the pipe without spatial limitation longitudinal. The energy and media expenditure required for this is in Relative to the cleaning effect achieved is usually disproportionately high. Pump wear is also very high.

Um die erforderliche Einsatzmenge der Reinigungsmedien zu verringern, wurde die Kammerung von zu reinigenden Abschnitten des Rohres bei sonst unverän­ derter Technologie vorgeschlagen (DD-PS 2 67 150). Damit wurde aber der Reinigungseffekt als solcher nicht verbessert und der Pumpenverschleiß nicht verringert.To reduce the required amount of cleaning media, was the chambering of sections of the pipe to be cleaned with otherwise unchanged other technology proposed (DD-PS 2 67 150). But that was the The cleaning effect as such is not improved and the pump wear is not decreased.

Ziel der Erfindung ist es, den Reinigungseffekt deutlich zu erhöhen und den Aggregateverschleiß zu mindern. Zusätzlich soll der Anfall von Abprodukten verringert werden.The aim of the invention is to significantly increase the cleaning effect and Reduce aggregate wear. In addition, the generation of waste products be reduced.

Hierzu soll die Aufgabe gelöst werden, den Kontakt des reinigenden Flüssig­ keits-Feststoff-Gemisches mit den verschmutzten Rohrwandungen zu verbessern und gleichzeitig auf Pumpen zum Antrieb des Reinigungsmediums zu verzichten.For this purpose, the task to be solved, the contact of the cleaning liquid ity-solid mixture with the dirty pipe walls to improve and at the same time dispense with pumps for driving the cleaning medium.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Vorrichtung zur Rohrreinigung, die bekanntermaßen aus einer durch das Rohr bewegten, abge­ dichteten Kammer besteht, im Innern der Kammer einen Rotor aufweist, dessen Drehachse mit der Rohrlängsache übereinstimmt, wobei die Kammer eine Fest­ stoff-Flüssigkeits-Suspension als Reinigungsmedium enthält. According to the invention the object is achieved in that the device for Pipe cleaning, which is known from a moving through the pipe, abge sealed chamber, has a rotor inside the chamber, the Axis of rotation coincides with the pipe length, the chamber being a fixed Contains liquid suspension as a cleaning medium.  

Folgende Ausgestaltungen führen zu besonders vorteilhafter Wirkung der Vorrichtung zur Rohrreinigung:
Der Rotor weist in der Nähe seiner Lagerungen schräg gestellte Zusatzflügel auf.
Der Rotor besteht aus mehreren, gelenkig miteinander verbundenen Teilro­ toren.
Die Kammer weist jeweils einen oder mehrere Zu- und Abflüsse zum Umlauf des Reinigungsmediums auf.The following configurations lead to a particularly advantageous effect of the device for pipe cleaning:
The rotor has inclined additional blades near its bearings.
The rotor consists of several articulated partial rotors.
The chamber has one or more inflows and outflows for the circulation of the cleaning medium.

An einem nachfolgenden Ausführungsbeispiel soll die Erfindung näher er­ läutert werden. Dabei zeigt die zugehörige Zeichnung eine schematische Darstellung einer Ausführungsform der erfindungsgemäßen Vorrichtung zur Rohrreinigung.In a subsequent embodiment, the invention he should to be refined. The accompanying drawing shows a schematic Representation of an embodiment of the device according to the invention Pipe cleaning.

Gemäß Zeichnung weist die Vorrichtung zur Rohrreinigung die Bestandteile,
Kammer 1 mit Begrenzungsplatten 2, Kammermanschetten 3,
Rotorlagerungen 4, Rotorwelle 5, Rotorflügel 6, Rotorantrieb 7,
Suspensionszuführung 8, Suspensionsabführung 9
auf.According to the drawing, the device for pipe cleaning has the components
Chamber 1 with boundary plates 2 , chamber sleeves 3 ,
Rotor bearings 4 , rotor shaft 5 , rotor blades 6 , rotor drive 7 ,
Suspension feed 8 , suspension discharge 9
on.

Die Vorrichtung wird mit einem Zugseil 10 durch ein zu reinigendes Rohr 11 gezogen. Währenddessen wird eine in der Kammer 1 befindliche Reinigungssus­ pension 12 aus einem Wasser-Feststoff-Gemisch durch die Rotorflügel 6 in Rotation versetzt. Der an der Rohrwandung des zu reinigenden Rohres 11 ein­ setzende Verschleiß einer anhaftenden Verunreinigungsschicht führt zum gewünschten Reinigungseffekt.The device is pulled with a pulling rope 10 through a pipe 11 to be cleaned. In the meantime, a cleaning suspension 12 located in the chamber 1 is set in rotation by the rotor blades 6 from a water-solid mixture. The settling wear of an adhering impurity layer on the pipe wall of the pipe 11 to be cleaned leads to the desired cleaning effect.

Dieses Wirkprinzip hat gegenüber der bisher angewendeten Längsdurchströmung folgende Vorteile für einen intensiveren Reinigungsprozeß:This principle of action has compared to the longitudinal flow used previously the following advantages for a more intensive cleaning process:

  • - Die hohe Relativgeschwindigkeit, die sich zwischen Reinigungssuspension 12 und Rohroberfläche ergibt, und die infolge der Fliehkraft wirkende große Normalkraft bewirken eine starke Intensivierung des reinigenden Ver­ schleißes. - The high relative speed that results between cleaning suspension 12 and pipe surface, and the large normal force acting as a result of the centrifugal force cause a strong intensification of the cleaning wear.
  • - Durch die Kammerung des rotierenden Systems werden sehr kleine Einsatzmen­ gen von Wasser und Feststoff gegenüber der Längsdurchströmung benötigt, wodurch auch geringe Mengen an Abprodukten anfallen.- The chambering of the rotating system means that very small amounts of work water and solids compared to the longitudinal flow, which also results in small amounts of waste products.
  • - Die unterschiedlichen Dichten von Luft, Wasser und Feststoff bewirken eine Phasentrennung dergestalt im rotierenden System, daß bei richtiger Mengen­ proportion die Rotorflügel 6 nur mit Wasser kontaktieren, welches wiederum die Reinigungssuspension 12 in Bewegung versetzt. Dadurch tritt am An­ triebssystem ein minimaler Verschleiß auf, was gegenüber dem intensiven Pumpenverschleiß beim Längsdurchströmen einen erheblichen Vorteil dar­ stellt. Ein Parameterbeispiel hierzu bilden ein etwa 50%iger Kammerfüllgrad mit Feststoff und ein Rotordurchmesser von ca. 75% des Rohrinnendurchmessers.- The different densities of air, water and solids cause a phase separation in such a way in the rotating system that, with the correct quantities, the rotor blades 6 only come into contact with water, which in turn sets the cleaning suspension 12 in motion. As a result, minimal wear occurs on the drive system, which represents a considerable advantage over intensive pump wear when flowing longitudinally. A parameter example of this is an approximately 50% degree of chamber filling with solids and a rotor diameter of approx. 75% of the inner tube diameter.
  • - Durch Anbau von mechanischen Verschleißhilfen am Rotor 5 kann die Verschleiß- und damit Reinigungsintensität weiter erhöht werden.- By mounting mechanical wear aids on the rotor 5 , the wear and thus cleaning intensity can be increased further.
  • - Durch eine Unterteilung des Rotors 5 in z. B. durch Kardan-Gelenke verbun­ dene Teilrotoren ist es leicht möglich, die Vorrichtung zur Rohrreinigung auch zur Reinigung gekrümmter Rohre einzusetzen.- By dividing the rotor 5 into z. B. by cardan joints verbun dene partial rotors, it is easily possible to use the device for pipe cleaning also for cleaning curved pipes.
  • - Mit zusätzlichen Flügeln, die in der Nähe der Rotorlagerungen 4 schräg zur Rotorwelle angeordnet sind, kann der Lagerbereich zusätzlich feststofffrei gehalten werden.- With additional vanes, which are arranged near the rotor bearings 4 at an angle to the rotor shaft, the bearing area can also be kept free of solids.
  • - Die Erfindung ist für die Rohrreinigung aller Rohrdurchmesser anwendbar, sofern die rein mechanische konstruktive Lösungsmöglichkeit von den Größenverhältnissen her gegeben ist. Ein besonderer Vorteil besteht darin, daß die Vorrichtung durch die flexiblen Kammermanschetten auch bei Durch­ messern innerhalb eines Rohrstranges anwendbar ist.- The invention is applicable for pipe cleaning of all pipe diameters, provided that the purely mechanical constructive solution of the Proportions is given forth. A particular advantage is that the device through the flexible chamber cuffs even through knives can be used within a pipe string.
  • - Die kontinuierliche Zu- und Abführungsmöglichkeit des Reinigungsmediums gestattet auch eine kontinuierliche Entkontaminierung.- The continuous supply and discharge option of the cleaning medium also allows continuous decontamination.
