Abstract
For the discontinuous desludging of salt baths an apparatus is used which consists of feed pipe (2), air supply line (1) and filter unit (3). The device additionally carries, at the lower end of the feed pipe, a base plate (7) having spacers (4) facing towards the bottom of the crucible and is provided with a suction endpiece (5) which can move telescopically in the feed pipe. <IMAGE>
