Abstract
An apparatus for detaching a filter cake created by a suction dryer from off the filter surface of a filter medium and for an essentially simultaneous treatment of the cake to a form advantageous for further processing. The apparatus comprises a suction dryer (1, 11, 27), a connected filter surface (4, 14, 28) and a basin (2, 13, 27) for the material to be filtered. According to the invention, in the vicinity of the filter surface (4, 14, 28) of the filter medium, there is installed a blowing member (7, 17, 21) with at least one part, the blowing effect whereof can advantageously be extended over the whole width of the filter surface (4, 14, 28) of the filter medium, on which surface the filter cake can be formed.
