Description

Reinigungskörper für Rohre in Wärmeaustauschern Zur Reinigung von Rohren geringen Durchmessers, wie sie in Wärmeaustauschern, z. B. Oberflächenkondensatoren, zur Verwendung gelangen, gebraucht man besondere Reinigungskörper, z. B. Gummipfropfen, die unter dem Druck eines strömenden Mittels, beispielsweise Wasser, durch das zu reinigende Rohr hindurchgedrückt werden. Um ein Festsetzen der Reinigungskörper im Rohr zu vermeiden, hat man schon vorgeschlagen, den Reinigungskörper so auszubilden, daß er auf seinem Wege -durch ,das zu reinigende Rohr durch die Druckflüssigkeit gleichzeitig in eine drehende Bewegung versetzt wird. ÄIan hat deshalb beispielsweise schraubenförmig gewundene Rippen auf dein Reinigungskörper angebracht, um entweder durch Reibung mit der inneren Rohrwand oder durch den Reaktionsdruck des aus dein schraubenförmigen Kanal austretenden Wassers eine Drehung herbeizuführen. Diese Anordnung hat den N achteil, daß die Rippen, die in erster Linie als Schabewerkzeug dienen, sich in die Schmutzschicht hineinarbeiten und deshalb unter Umständen der Druckflüssigkeit keinen Durchtritt mehr gewähren. Damit hört aber auch die Drehung des Reinigungskörpers, wenn sie etwa durch den Reaktionsdruck der aus dem schraubenför urigen Kanal austretenden Druckflüssigkeit aufgebracht sein sollte, auf.Cleaning body for pipes in heat exchangers For cleaning Small diameter tubes such as those used in heat exchangers, e.g. B. surface capacitors, get to use, you need special cleaning body, z. B. rubber stopper, which under the pressure of a flowing medium, for example water, through which to cleaning pipe are pushed through. To fix the cleaning body to avoid in the pipe, it has already been proposed to design the cleaning body so that he is on his way through the pipe to be cleaned through the hydraulic fluid is set in a rotating motion at the same time. So, for example, ÄIan has helically wound ribs attached to your cleaning body to either by friction with the inner pipe wall or by the reaction pressure of the out of your helical channel of exiting water to cause a rotation. These Arrangement has the disadvantage that the ribs, which are primarily used as a scraping tool serve, work your way into the layer of dirt and therefore possibly the Do not allow hydraulic fluid any more passage. But that also stops the rotation of the cleaning body when it is caused by the reaction pressure of the screw conveyor rustic channel exiting hydraulic fluid should be applied to.

Dieser Nachteil wird durch die Erfindung vermieden. Sie besteht darin, claß der Reinigungskörper mit mehreren an seiner Stirnfläche mündenden Durchtrittskanälen für die Druckflüssigkeit verseben ist, die einen Winkel sowohl mit der waagerechten als auch mit der senkrechten Achse des Reinigungskörpers bilden. Bei dieser Anordnung ist ein ungestörter Austritt des Wassers aus den Kanälen möglich. Eine Drehung des Reinigungskörpers wird deshalb in jedem Falle bewirkt werden. Diese Anordnung hat noch weiterhin ,den Vorteil, daß durch das aus dem Durchtrittskanal austretende Wasser eine wirksame V orspülung erfolgt, durch die die Schmutzschicht gelockert wird und leichter entfernt werden kann.This disadvantage is avoided by the invention. It consists in claß the cleaning body with several opening channels at its end face for the hydraulic fluid is verseben, which is an angle with both the horizontal as well as with the vertical axis of the cleaning body. With this arrangement an undisturbed discharge of the water from the canals is possible. A twist of the Cleaning body will therefore be effected in any case. This arrangement has still further, the advantage that through the emerging from the passage channel An effective pre-rinse takes place with water, which loosens the layer of dirt and can be removed more easily.

In den Abbildungen ist ein Reinigungskörper gemäß der Erfindung dargestellt. Mit Hilfe von Wasser wird der Reinigungskörper -a durch das Rohr i hindurchgetrieben. Der Kö rpc r 2 besitzt eine Reihe von Bohrungen 3, von denen in der Abb. i nur eine angedeutet ist. Die Löcher 3 laufen in eine Bohrung aus, die in einem Winkel zu der waagerechten und zu der senkrechten Achse des Reinigungskörpers steht. Durch diese Art der Formgebung wird beim Ausströmen des Wassers ein Reaktionsdruck auf den Reinigungskörper ausgeübt, der ihn in Drehung versetzt. Diese Drehung und die aus den Bohrungen d. austretenden Wasserstrahlen bewirken eine wirksame Reinigung des Rollres. Die Vorwärtsbewegung erfolgt in Richtung des eingezeichneten Pfeiles. -Man kann auf den Umfang des Körpers 2, wenn härtere Ablagerungen zu befürchten sind, noch kleine Fräserzähnchen oder Bürsten anbringen, die die Reinigung noch wirksamer gestalten.In the figures, a cleaning body according to the invention is shown. The cleaning body -a is driven through the pipe i with the aid of water. The body rpc r 2 has a number of holes 3, of which in Fig. I only one is indicated. The holes 3 run into a hole that is at an angle the horizontal and vertical axis of the cleaning body. By this type of shaping creates a reaction pressure when the water flows out exercised the cleaning body, which sets it in rotation. That twist and that from the holes d. escaping water jets cause effective cleaning des Rollres. The forward movement takes place in the direction of the arrow. -One can move on to the circumference of the body 2 if harder deposits are to be feared still attach small milling teeth or brushes that still do the cleaning make it more effective.
