<p>The invention relates to an arrangement for cleaning a wool chamber in the manufacture of mineral wool. In the manufacture of mineral wool a binder is added to the stream of fibers (1) which is deflected towards the wool chamber and said binder deposits itself in fine droplets on the fibers. The binder-loaded fibers which touch against the walls and roof of the wool chamber adhere to them because the binder hardens upon contact with the hot surfaces. Gradually a hard deposit of binder and fibers is formed upon the walls. According to the invention cleaning of the walls is substantially simplified by means of making the walls (6, 9) and/or the roof of a double-walled construction, perforating the inner walls (6) and applying a reduced pressure in the cavity (7) between the walls and holding a detachable lining (8) against the inner walls by means of suction. When said detachable lining has become coated with deposits of binder and fibers to a certain thickness production is halted and the reduced pressure is broken off, whereon the detachable lining together with the deposits falls off and a new detachable lining or linings (8) respectively are applied to the perforated walls (6).</p> |
