摘要： Apparatus for pressure drainage of organic sewage sludge, industrial sludge and special waste sludge of varying composition includes a fully automatic sludge conditioning unit for preparing a flocculating agent and a fully automatic sludge feeding unit for a pressure reactor which includes a press plunger reciprocating on filter candles between axial end plates. The press plunger cooperates with a riser pipe situated outside of each end plate and incorporating a motor-driven discharge valve. The riser pipe communicates with a screw conveyor which is mounted to the pressure reactor for further transport of filter cake to a container.

摘要： Apparatus for partial dewatering of raw sludge, includes at least two filter units each defining a filter chamber which receives raw sludge and has an outer wall surface formed as filter for discharge of filtrate from raw sludge. Accommodated within the filter chamber is a double-acting plunger which extends across the entire cross section for dividing the filter chamber in two working chambers, and reciprocates in the filter chamber along the inside wall surface for movement between a first end position and a second end position, with each working chamber having an inlet for receiving raw sludge from a suitable conveying unit and an outlet for discharge of partially dewatered raw sludge. A control unit actuates valves for regulating a flow of raw sludge into the working chambers, such that raw sludge entering one working chamber forces the plunger to move from the first end position to the second end position, and raw sludge entering the other working chamber forces the plunger to move from the second end position to the first end position.
摘要翻译：用于原料污泥部分脱水的装置包括至少两个过滤器单元，每个过滤器单元限定过滤室，该过滤器容纳生污泥并具有形成为过滤器的外壁表面，用于从原污泥中排出滤液。容纳在过滤室内的是双作用柱塞，其横跨整个横截面延伸，用于将过滤室分隔成两个工作室，并沿着内壁表面在过滤室中往复运动，以在第一端位置和第二端之间移动位置，每个工作室具有用于从合适的输送单元接收原料污泥的入口和用于排出部分脱水的原始污泥的出口。控制单元致动用于调节原料污泥流入工作室的阀门，使得进入一个工作室的原料污泥迫使柱塞从第一端部位置移动到第二端部位置，而进入其它工作室的原料污泥力所述柱塞从所述第二端部位置移动到所述第一端部位置。
