Zusammenfassung:The invention relates to a device for detaching a filter cake which adheres to a filter cloth of a filter press, comprising at least two deflection bodies around which the filter cloth extends in an S-shaped manner and which can be moved in an approximately vertical direction, so that the S-shaped deflection brushes essentially completely over the adhering area of the filter cake. Such a device has already been realized in the filter press for the filtration of suspensions as known from EP 0 718 020 A1. The deflection bodies are arranged in this case as two horizontally aligned rollers which are disposed at opposite sides of the filter cloth and are provided with a horizontal as well as vertical offset of their rotational shafts. Both rollers are combined into a module by way of coupling elements which are provided with laterally projecting carriers which enable all pairs of rollers to be simultaneously brought into engagement with a vertically movable lifting device and can thus be moved upwardly and downwardly. A device () for detaching a filter cake which adheres to a filter cloth () of a filter press, comprising at least two deflection bodies () around which the filter cloth () extends in an S-shaped manner and which can be moved in an approximately vertical direction, so that the S-shaped deflection brushes essentially completely over the adhering area of the filter cake. In order to achieve a complete detachment even in the case of filter cake which is not fully filtered out it is proposed filter cloth () extends in a sliding fashion during a relative movement between the same deflection bodies () over a surface of one deflection body () and is provided with bend () in its course at a longitudinal edge () of said deflection body ().
