Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf solche Kesselrohrreiniger, bei welchen mit Zähnen versehene Platten auf federnden Schenkeln befestigt sind. Die Neuerung besteht nun darin, daß diese Platten trapezförmig sind, so daß die zwischen denselben entstehenden Spalten . zur Achse schief stehen, wodurch das Rohr zugleich auf dem ganzen inneren Umfang gereinigt wird und nicht, wie dies bei gerade zur Achse gestellten Spalten der Fall wäre, die von den Spalten überlaufenen inneren Rohrteile ungereinigt bleiben. Die Zahnreihen auf den Platten sind schraubenförmig angeordnet, so daß der Rohrreiniger sich beim Durchziehen durch das Rohr dreht.The invention relates to such boiler tube cleaner, in which with teeth provided plates are attached to resilient legs. The innovation now consists in that these plates are trapezoidal, so that the resulting gaps between them. to the Axis are at an angle, which means that the tube is cleaned on the entire inner circumference at the same time and not, as would be the case with columns that are straight to the axis, the inner pipe parts overflowing from the gaps remain uncleaned. The rows of teeth open the plates are arranged helically so that the pipe cleaner is pulled through rotates through the pipe.
Auf der Zeichnung ist der neue Rohrreiniger dargestellt. Es zeigt Fig. 1 einen Längsschnitt, Fig. 2 einen Grundriß, in der Richtung der Längsachse gesehen, Fig. 3 die Ansicht einer einzelnen mit Schneidezähnen versehenen Platte.The drawing shows the new drain cleaner. It shows Fig. 1 a longitudinal section, Fig. 2 is a plan view, seen in the direction of the longitudinal axis, Fig. 3 is a view of a single plate provided with incisors.
An einem mit einer Öse α versehenen Kopf b On a head provided with an eyelet α b
sind mehrere federnde Lamellen c befestigt, deren freie Enden nach außen federn und je mit einer mit Zähnen d versehenen Platte e ausgerüstet sind. Diese Platten haben, wie aus Fig. 3 ersichtlich, eine trapezförmige Gestalt und sind, wie aus Fig. 2 zu erkennen, derart nebeneinander angeordnet, daß immer eine größere Seite des Trapezes auf eine kleinere folgt. Hierdurch wird bewirkt, daß die zwischen den einzelnen Platten vorhandene Spalte/ zur Achse des Rohrreinigers schräg liegt. Wird daher diese Vorrichtung durch die Rohre hindurchgezogen, so kann die Spalte/ in der abzukratzenden Schicht der Dampfkesselrohre keine Spur hinterlassen, sondern die ganze verunreinigende Schicht wird durch die Zähne der Platten abgekratzt.Several resilient lamellae c are attached, the free ends of which spring outwards and are each equipped with a plate e provided with teeth d . As can be seen from FIG. 3, these plates have a trapezoidal shape and, as can be seen from FIG. 2, are arranged next to one another in such a way that a larger side of the trapezoid always follows a smaller one. This has the effect that the gap between the individual plates / is inclined to the axis of the pipe cleaner. Therefore, if this device is pulled through the pipes, the gap / in the layer of the steam boiler pipes to be scraped off cannot leave a trace, but the entire contaminating layer is scraped off by the teeth of the plates.
Die Zähne d der Platten e besitzen Dreiecksform und sind, wie aus Fig. 3 zu ersehen, in diagonalen Reihen angeordnet, so daß die Schneidkanten schräg zu der Zugrichtung liegen. Wie ersichtlich, wird die Bewegung des Rohrreinigers beim Durchziehen durch die Kesselrohre derart beeinflußt, daß derselbe sich in Schraubenform durch das Kesselrohr windet. Auch hierdurch wird also bewirkt, daß jeder Teil des Kesselrohres von den Zähnen d gereinigt wird.The teeth d of the plates e have a triangular shape and, as can be seen from FIG. 3, are arranged in diagonal rows so that the cutting edges are inclined to the direction of pull. As can be seen, the movement of the pipe cleaner when it is pulled through the boiler tubes is influenced in such a way that the same winds in helical form through the boiler tube. This also has the effect that every part of the boiler tube is cleaned of the teeth d.
Vermöge der federnden Lamellen c paßt sich die Vorrichtung verschiedenen Kesselrohrdurchmessern an, wobei die Spalten f sich bezüglich ihrer Breite entsprechend ändern.By virtue of the resilient lamellae c , the device adapts to different boiler tube diameters, the gaps f changing accordingly with regard to their width.
