用于纸浆脱水的机器
摘要：
本发明涉及一种用于纸浆脱水的机器(100)，其具有配备下部筛网(3)和上部筛网(4)的成型器(2)，所述下部筛网(3)和上部筛网(4)至少在一段距离上构成双筛网区域(5)并且因而与在它们之间的、从流浆箱(6)施加到下部筛网(3)上的纸浆一起被引导经过转向辊(7)，其中双筛网区域(5)在下部筛网(3)的筛网运行方向(S)上前置有由下部筛网的部段构成的预脱水区域(8)，所述预脱水区域界定一个平面(8.E)，其中转向辊(7)在下部筛网(3)的筛网运行方向(S)上后置有引导两个筛网(3,4)的另一个转向辊(12)，并且其中转向辊(7)以及另一个转向辊(12)在空间上设置在由预脱水区域(8)界定的平面(8.E)的上方。按照本发明的机器(100)的特征在于，至少一个转向辊(7,12)、优选两个转向辊(7,12)设有具有至少一个抽吸区或压力区(16)的开口的辊套(7.M,12.M)。
摘要（英）：

The invention relates to a machine (100) for dewatering pulp (1), comprising a former (2) with a lower wire (3) and an upper wire (4), which, at least over certain lengths, form a twin wire zone (5) and which are guided over a deflection roller (7) with the pulp (1) which lies therebetween and has been applied to the lower wire (3) from a headbox (5), wherein a pre-dewatering zone (8) formed from a portion of the lower wire (3) is arranged upstream of the twin wire zone (5) in the direction (S) of movement of the lower wire (3), said pre-dewatering zone spanning a plane (8.E), wherein a further deflection roller (12) guiding both wires (3, 4) is arranged downstream of the deflection roller (7) in the direction (S) of movement of the lower wire (3), wherein both the deflection roller (7) and also the further deflection roller (12) are spatially arranged above the plane (8.E) spanned by the pre-dewatering zone (8). The machine (100) according to the invention is characterised in that at least one of the deflection rollers (7, 12), preferably both deflection rollers (7, 12), are designed with an open roller sleeve (7.M, 12.M) having at least one suction or pressure zone (16).
