Description
Schabevorrichtung zum Reinigen der KÜW- oder Heizrohre in Wärmeaustauschern Die Erfindung bezieht sich auf eine Schabevorrichtung zum Reinigen der Kühl- oder Heizrohre in Wärmeaustauschern, die aus einem oder mehreren längs der Röhre beweglichen plattenförmigen Schiebern mit die einzelnen Rohre elastisch umgreifenden Schabringen besteht.Scraper device for cleaning the KÜW or heating pipes in heat exchangers The invention relates to a scraping device for cleaning the cooling or Heating tubes in heat exchangers consisting of one or more movable along the tube Plate-shaped sliders with scraper rings that elastically encompass the individual tubes consists.
Bei einer bekannten Schabevorrichtung dieser Art sitzen die Schabringe unbeweglich in dem plattenförmigen Schieber und sind aus einem nachgiebigen Werkstoff hergestellt. Diese Vorrichtung hat den Nachteil, daß die Schabringe einer starken Abnutzung unterworfen sind und schon nach kurzem Gebrauch nicht mehr dicht an den Rohren anliegen. Gerade durch die Verwendung eines nachgiebigen, also nichtmetallischen Werkstoffes für die Schabringe wird der Verschleiß der letzteren sehr begünstigt. Außerdem besteht die Gefahr, daß beim Bewegen des Schiebers längs der Röhre, besonders wenn diese sich gekrümmt haben, Klemmungen auftreten können.In a known scraping device of this type, the scraper rings are seated immobile in the plate-shaped slide and are made of a flexible material manufactured. This device has the disadvantage that the scraper rings have a strong Are subject to wear and tear and are no longer close to the after a short period of use Pipes are in contact. Especially through the use of a flexible, i.e. non-metallic one Material for the scraper rings, the wear of the latter is very favored. There is also the risk that when moving the slide along the tube, especially if they have curved, jamming can occur.
Diese Nachteile werden nach der Erfindung dadurch vermieden, daß jeder Schieber aus zwei die Schabringe lose zwischen sich einschließenden parallelen Platten besteht und jeder Schabring in mehrere durch ein gemeinsames - Band gegen den Umfang des zugehörigen Rohres angedrückte starre Ringsegmente unterteilt ist. Infolge ihrer beweglichen Anordnung zwischen den beiden Platten des Schiebers können die Schabringe entsprechend den Krümmungen oder sonstigen Unregelmäßigkeiten des Rohres seitlich ausweichen, @ so daß ein Klemmen des Schiebers niemals eintreten kann. Außerdem wird trotz der unvermeidlichen, wenn auch geringfügigen Abnutzung ein dauernd gleichmäßig dichtes Anliegen der Schabringe am ganzen Umfang der Rohre gesichert, da sich jeder in mehrere Segmente unterteilte Schabring nach Maßgabe der Abnutzung selbsttätig verengen kann.These disadvantages are avoided according to the invention in that each Slider made of two parallel plates, loosely enclosing the scraper rings between them consists and each scraper ring in several by a common - band against the circumference of the associated pipe pressed rigid ring segments is divided. As a result of her movable arrangement between the two plates of the slide can be the scraper rings laterally corresponding to the curvatures or other irregularities of the pipe evade, @ so that the slide can never jam. aside from that becomes permanently even in spite of the inevitable, albeit minor wear tight fit of the scraper rings on the entire circumference of the pipes, as everyone Automatic scraper ring divided into several segments according to wear can narrow.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Abb. r zeigt den in einem Wärmeaustauscher beweglich angeordneten Schieber im Schnitt.An exemplary embodiment is shown in the drawing. Fig.r shows the slider movably arranged in a heat exchanger in section.
Abb.2 zeigt iri größerem Maßstab einen Teil des Schiebers im Schnitt.Fig. 2 shows on a larger scale a part of the slide in section.
Abb.3 zeigt in Draufsicht einen Schäbring. - ' Der in dem nicht näher dargestellten Wärmeaustauscher T mittels einer Schraubenspindel e o. dgl. längs der Kühl- oder Heizrohre 3 bewegliche Schieber besteht aus zwei parallelen Platten 4.a und q.6, die in einiger Entfernung voneinander mittels vernieteter Bolzen 5 starr miteinander verbunden sind und Löcher 6a und 66 besitzen, durch die sich die Rohre 3 mit Spielraum erstrecken. Zwischen den Platten q.a und q6 sind die Schabringe 8 lose angeordnet, welche die Rohre 3 dicht umschließen. Jeder Schabring besteht aus vier Segmenten 8a, 86, 8e, 8d; die durch ein gemeinsames elastisches Band 9 gleichmäßig gegen den Umfang des betreffenden Rohres angedrückt werden. Das elastische Band 9 liegt in einer Umfangsnut ro des Schabringes.Fig.3 shows a Schäbring in plan view. - 'The slide in the heat exchanger T, not shown in detail, by means of a screw spindle e or the like along the cooling or heating pipes 3 consists of two parallel plates 4.a and q.6, which are rigid at some distance from one another by means of riveted bolts 5 are interconnected and have holes 6a and 66 through which the tubes 3 extend with clearance. The scraper rings 8, which tightly enclose the tubes 3, are loosely arranged between the plates qa and q6. Each scraper ring consists of four segments 8a, 86, 8e, 8d; which are pressed evenly against the circumference of the pipe in question by a common elastic band 9. The elastic band 9 lies in a circumferential groove ro of the scraper ring.
Der Schabring 8 kann aus Stahl, Fiber, Leder oder einem anderen geeigneten Werkstoff bestehen.The scraper ring 8 can be made of steel, fiber, leather or another suitable one Material.
