KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Vorrichtung zur inneren Reinigung von Siederöhren mit schräg geriffelten Schneidrollen und unterscheidet sich von bekannten derartigen Vorrichtungen dadurch, daß die Schneidrollen senkrecht zur Rohrachse und versetzt zueinander angeordnet sind, um den Kesselstein in der Längsrichtung der Röhren abzukratzen. Der abgekratzte Kesselstein wird hierbei durchThe invention relates to a device for the internal cleaning of boiler tubes with inclined corrugated cutting rollers and differs from known such devices in that that the cutting rollers are arranged perpendicular to the pipe axis and offset from one another to scrape off the scale along the length of the tubes. The scraped off Scale is here by
ίο zwischen den Rillen der Rollen vorgesehene Abstreifer von den Rollen entfernt. Insbesondere soll die neue Vorrichtung für Röhrenkessel in großen Betrieben geeignet sein, welche mit mechanischen Beschickungen, vorgelagerten Kohlenbunkern und Wagen versehen sind und wo der Platz beschränkt ist. In Fig. ι ist die vollständige Vorrichtung, in Fig. 2 die Rollenlagerung mit Hebel in größerem Maßstab, ebenso in Fig. 3 eine geriffelte Rolle mit Abstreifer und in Fig. 4 das Kreuz zur Aufnahme der Rollenhebel dargestellt. ίο provided between the grooves of the rollers Wiper removed from the rollers. In particular, the new device for tubular boilers be suitable in large companies with mechanical feeds upstream Coal bunkers and wagons are provided and where space is limited. In Fig. Ι the complete device is in Fig. 2 the roller bearing with lever on a larger scale, also in Fig. 3 a corrugated Roller with scraper and in Fig. 4 the cross for receiving the roller lever is shown.
Auf einer gewundenen Vierkantachse α sind in zwei Abständen die schräg geriffelten Rollen b an Hebeln c mit. je einem Kreuzstück d durch Stifte e verbunden. Das Kreuzstück erhält am unteren Ende einen Gewindeansatz f, auf welchen eine Kegelmutter g zur Verstellung der mit gleichen Abschrägungen versehenen Hebel c geschraubt ist. Die Hebel c erhalten ferner anpressende Federn h; ferner sind die Rollen b zwischen den einzelnen Riffeln mit Abstreifern i versehen. Zur Entfernung und Nachreinigung des in den Siederöhren lagernden Kesselsteinmehles sind an den beiden Enden der Vorrichtung Stahlbürsten k angebracht.On a winding square axis α , the inclined corrugated rollers b on levers c are at two intervals. each connected to a cross piece d by pins e . The cross piece has a threaded attachment f at the lower end, onto which a conical nut g is screwed to adjust the lever c, which is provided with the same bevels. The levers c also receive pressing springs h; furthermore, the rollers b are provided with scrapers i between the individual corrugations. Steel brushes k are attached to both ends of the device for removing and cleaning the scale powder stored in the boiler tubes.
Der Arbeitsvorgang ist folgender: An beiden Enden der Wasserkammer werden Vorgelegetrommeln für Ketten, Seile oder Stahlbänder angebracht, an welchen beiderseits die Vorrichtung befestigt wird und an welchen sie alsdann durch das Rohr hindurch bzw. hin und her gezogen wird, bis das Rohr metallisch rein ist. Durch die Vorrichtung werden Zeitersparnis und geringer Arbeitsaufwand erstrebt. .The process is as follows: There are countershaft drums at both ends of the water chamber for chains, ropes or steel bands attached to which the device is attached on both sides and to which it is then pulled through the pipe or back and forth until the pipe becomes metallic is pure. The device saves time and reduces labor strives. .
