Title
(ZH) 用于防止纸浆再润湿的装置
Abstract
(ZH)

一种用于在纸浆处理设备中防止纸浆再润湿的装置(302),所述纸浆处理设备包括至少一个转筒(202,204),其设有可渗透的外表面(208,208)和从外表面(206,208)向内设置的多个轴向滤出液通道(210,212)。纸浆处理设备通过至少从纸浆去除液体并将液体从纸浆经过外表面(208,208)输送至滤出液通道(210,212)来处理纸浆。该装置(302)适于安装在多个滤出液通道(210,212)中的一个滤出液通道中,并包括:轴向延伸的滤出液屏障(304),用于防止液体从滤出液通道(210,212)的尾部流动至转筒(202,204)的外表面(206,208);以及至少一个连接至滤出液屏障(304)的轴向延伸的支承元件(306)。至少一个偏置构件(308,310,312)适于偏置滤出液屏障(304)离开支承元件(306)而到达相对于支承元件(306)的第一未偏置位置,在所述第一未偏置位置,提供装置(302)的伸长的横向延伸范围,并且适于偏置滤出液屏障(304)离开支承元件(306)而到达相对于支承元件(306)的至少一个第二未偏置位置,在所述第二未偏置位置,提供所述装置(302)的缩短的横向延伸范围。一种纸浆处理设备包括所述装置(302)。
