摘要： A method of mixing paper stock, having improved outlet consistency, includes: (a) feeding liquid and feeding paper pulp into a vessel to form a mixture; (b) providing at least one counterflow impeller that is submerged in the mixture, the counterflow impeller being capable of simultaneously inducing both upward flow and downward flow; (c) rotating the counterflow impeller such that downward flow from the impeller is partially recirculated by upward flow from the impeller to form a mixing zone; (d) sensing a parameter of the mixture discharged from the vessel; and (e) controlling the feed rate of the liquid and the feed rate of the paper pulp in the feeding step (a) based on the sensing step (d). An apparatus for mixing of paper stock, having improved outlet consistency, includes a vessel for containing liquid and paper pulp, at least one counterflow impeller, and a feedback system for controlling outlet consistency.
摘要翻译：具有改进的出口稠度的纸料混合方法包括：（a）送液并将纸浆送入容器中以形成混合物; （b）提供至少一个浸没在混合物中的逆流叶轮，逆流叶轮能够同时引导向上流动和向下流动; （c）旋转逆流叶轮使得来自叶轮的向下流动部分地通过来自叶轮的向上流动再循环以形成混合区域; （d）感测从容器排出的混合物的参数; 以及（e）基于感测步骤（d），在进料步骤（a）中控制液体的进料速率和纸浆的进料速率。具有改进的出口稠度的纸料混合装置包括容纳液体和纸浆的容器，至少一个逆流叶轮和用于控制出口稠度的反馈系统。
