Abstract (en)

[origin: EP1342574A2] The filtering system/device consists of a ring-band filtering system that has a filter band (28) that moves forward the saturation with dirt particles. The filter band may be transportable between the supply station (30) and the collection station (32). The filter band may be U-shaped with the lower peripheral region having a drum-like lining. The filter band may begin from below via a perforated support band (36) that may be in the form of an end-less band that may be transportable around rollers (38, 40, 42, 44) from the height of the lower, middle as well as upper region of the drum-like arrangement. The support band may be moved forward around two of the lower and two of the upper rollers.
