概述 DESCRIPTION
该机主要用于碱法、酸法蒸煮木浆、竹浆及草浆等的黑液提取及浓缩，也用于废纸浆的浓缩及废液提取。它利用一根变径和变螺距的螺旋旋转时所产生的空间容积变化来挤压纤维，实现黑液提取及浆料浓缩。具有黑液提取率高、纤维流失少、对浆料适应范围广等优点。
This machine mainly uses in the alkaline process, the acid cooking wood-pulp, the bamboo thick liquid and the straw pulp and so on black liquor extraction and the concentration, also uses in the waste paper pulp the concentration and the waste liquid extraction. The space volume change which it uses one changes the diameter and changes pitch when screw revolving produces extrudes the textile fiber, realizes the black liquor extraction and the pulp concentration. Has the black liquor extraction rate to be high, the textile fiber class lacks broadly, to the pulp adaptation scope and so on merits.
