Abstract (en)
[origin: EP0369851A1] Method for continuously cleaning the interior of a tube (10) wherein a fluid is circulating, according to which a moveable element (11) is driven in continuous rotation within this tube by means of said fluid, one end of which moveable element is fastened to one end of the tube by a mechanical linkage (1,5) leaving it free to turn on itself about the axis of the tube. <??>Said moveable element comprises at least one sharp edge intended to scrape the internal surface of the tube, which is disposed so that in the course of the rotation of the moveable element it constitutes, along any transverse cross-section of the tube, that part of the moveable element which is furthest from the axis of the tube. <IMAGE>
