摘要
A bagasse bed dewatering apparatus comprises a pressure sieve roll (3) having drainage channels (4) with open channel ends (7) which rotate past perforated walls through which collected liquid is drained into a collection tank. A bagasse bed dewatering apparatus comprises a transverse pressure sieve roll (3) which is located at the end of a transporter-like diffuser and which has welded perforated V-profiled drainage channels (4) with open channel ends (7) rotating past perforated diffuser side walls through which collected liquid is drained into a collection tank. An Independent claim is also included for a similar apparatus in which the roll (3) has a double-walled casing with a perforated outer wall and an inner wall which supports webs for forming the drainage channels. Preferred Features: The V-profiled drainage channels may have a trapezoidal cross-section with perforations extending only over two-thirds of their height and with a closed bottom. Alternatively, each V-profiled drainage channel has a triangular cross-section with a rounded apex which is free of perforations, the channel being formed by a 90 deg angle profile. In the double-walled form of the roll, the outer wall has welded entrainment profiles positioned in the radial planes of the webs, at least some of the entrainment profiles forming perforated drainage channels. The radial heights of the drainage channels may increase uniformly from a minimum value near the roll middle to a maximum value at the channel ends (7).
