摘要： The invention relates to an apparatus, in particular a machine, for the pressing and dewatering or filtering of sludges, fibrous material suspensions or cellulosic material suspensions, having two circulating filter belts or screen belts between which the material to be pressed, dewatered or filtered is made to pass, and two circulating pressure belts or supporting belts for supporting said two filter belts on their sides facing away from the material to be treated, with supporting or pressure means, in particular stationary during the operation of the apparatus, for the pressure or supporting belts on their sides facing away from the filter belts or the material to be treated. The invention is characterized mainly in that the supporting or pressure means form a tunnel, in particular a pressure space, preferably with straight longitudinal axis, in the compression, dewatering and filtering zone, the pressure and supporting belts being sealed against the tunnel or pressure space walls directly or indirectly, locally defined, in particular in several locations of the tunnel or pressure space, by elastic belts or the like at least essentially enclosing the pressure or supporting belts and the filter belts and the material to be treated on all sides.
摘要翻译：本发明涉及一种用于压榨和脱水或过滤污泥，纤维材料悬浮液或纤维素材料悬浮液的装置，具有两个循环过滤带或筛网带，其中被压榨，脱水或过滤的材料在其之间是以及两个循环的压力带或支撑带，用于在其所处的背面上支撑所述两个过滤带，所述两个过滤带背离待处理的材料，具有支撑或压力装置，特别是在装置的操作期间是静止的，用于压力或支撑皮带的背面背离过滤带或被处理材料。本发明的特征主要在于，在压缩，脱水和过滤区域中，支撑或压力装置形成隧道，特别是压力空间，优选具有直的纵向轴线，压力和支撑带被密封抵靠隧道或压力空间通过弹性带等至少基本上包围压力或支撑带以及过滤带和待处理的材料在所有方面直接或间接地局部限定，特别是在隧道或压力空间的若干位置。
