A scraper blade holding system on scraper shafts of scraper coolers in which the scraper blade, by means of springs, connecting elements, and guiding elements for the springs, is in continuous contact with the inner wall of the inner tube of a double tube structure. The scraper blade holding system is characterized primarily in that transverse bores of the scraper shaft end are freely axially movably arranged holding bolts which at their outer ends directed to the inner wall of the inner tube are equipped with tubular sleeves connected to the scraper blades, which sleeves are pressed outwardly by helical pressure springs surrounding the holding bolts and are supported by the scraper shaft. |
