PATENTAMT.PATENT OFFICE.
Die neue Vorrichtung zum Reinigen der Röhren von Wasserrohrkesseln von Kesselstein ist auf beiliegender Zeichnung zur Darstellung gebracht, und zwar bedeutet Fig. ι eine Seitenansicht, Fig. 2 eine obere Ansicht derselben.The new device for cleaning the pipes of water-tube boilers from scale is shown on the accompanying drawing, namely Fig. ι a side view, Fig. 2 is a top view of the same.
Die beiden Blattfedern α sind an ihrem unteren Ende durch Bolzen oder Niete mit einem Zapfen verbunden, welcher einen schraubenartigen Ansatz c zur Befestigung eines Handgriffes besitzt. Die Bewegung der Federn d nach aufsen wird durch ein Kettenglied e begrenzt, wodurch die an den Federn drehbar angeordneten zweiarmigen Hebel f und damit die an den freien Enden dieser Hebel sitzenden Arbeitsrollen in der richtigen Lage erhalten werden. Die um ihren Befestigungspunkt schwingenden Hebel haben den Zweck, ein gleichmä'fsiges Anpressen der Arbeitsrollen und damit eine gleichmäfsige Reinigung zu erzielen. Die Arbeitsrollen g und h haben die aus der Zeichnung ersichtliche bekannte Gestalt und können z. B. gegen einander versetzt sein, wie aus Fig. 2 ersichtlich ist.The two leaf springs α are connected at their lower end by bolts or rivets to a pin which has a screw-like projection c for attaching a handle. The outward movement of the springs d is limited by a chain link e , as a result of which the two-armed levers f , which are rotatably arranged on the springs, and thus the work rollers seated at the free ends of these levers, are kept in the correct position. The purpose of the levers swinging around their fastening point is to achieve uniform pressing of the work rollers and thus uniform cleaning. The work rolls g and h have the known shape shown in the drawing and can, for. B. offset from one another, as can be seen from FIG.
Die freien Enden der Federn α werden, wie bekannt, noch durch eine Spiralfeder aus einander gedrückt, wodurch die Wirkung noch erhöht wird und aufserdem die federnden Arme entlastet werden.The free ends of the springs α are, as is known, pressed from one another by a spiral spring, whereby the effect is increased and the resilient arms are also relieved.
Um die Vorrichtung in ein Rohr einzuführen, werden die Federn etwas zusammengedrückt, und sobald sie sich in dem Rohre befindet, erfolgt ein Nachaufsenpressen der Arbeitsrollen durch die Federn, so dafs die Rollen mit einer gewissen Kraft gegen die Rohrwandung angeprefst werden. Beim Hin- und Herbewegen der Vorrichtung in dem Rohre legen sich die Rollen je nach der Dicke der Kesselsteinschicht mit gröfserer oder geringerer Kraft gegen die Wandung, zermalmen die Steinschicht und bewirken deren Ablösung von der Wandung.To insert the device into a tube, the springs are compressed a little, and as soon as it is in the tube, the working rollers are pressed on by the springs, so that the Rollers are pressed against the pipe wall with a certain force. When going and moving the device in the tube, the rolls lie depending on the thickness crush the scale layer with greater or lesser force against the wall the stone layer and cause it to be detached from the wall.
