<p>The apparatus for continuous filtration and drying of a solid suspension comprises a belt filter (1) and a subsequent belt dryer (2). The filter cake generated in the belt filter (1) is transported further by a porous transport belt (3) into the belt dryer (2) in which heaters are provided for heating and drying the filter cake (7) situated on the transport belt (3). After it leaves the belt filter (1), the filter cake (7) is present on the transport belt (3) in the form of a layered, gas-permeable solids bed having a layer thickness of at most 50 mm, preferably at most 20 mm. The heaters in the belt dryer (2) comprise on the one hand a hot gas chamber (8) arranged above the transport belt (3) to generate a hot gas flowing through the solids bed from top to bottom and, on the other hand, one or more contact heating elements (10, 15, 18, 19, 20, 22) arranged above and/or beneath the transport belt (3). <IMAGE></p> |
