<p>PCT No. PCT/EP96/02068 Sec. 371 Date Jan. 23, 1998 Sec. 102(e) Date Jan. 23, 1998 PCT Filed May 14, 1996 PCT Pub. No. WO96/38391 PCT Pub. Date Dec. 5, 1996The 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 which is deflected towards the wool chamber and the binder deposits itself in fine droplets in the fibers. The binder-laden 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 and/or roof of a double walled construction, perforating the inner walls and applying a reduced pressure in the cavity between the walls holding a detachable lining against the inner walls by means of suction. When the 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 is applied.</p> |
