METHOD AND APPARATUS FOR TRANSPORTING VISCOUS MATERIAL

Apparatus and method for transporting nanofibrillar cellulose in the form of viscous liquid dispersion. The nanofibrillar cellulose is unloaded from a container (3) through a discharge point (3b) which is the lowermost point with respect to the volume of nanofibrillar cellulose in the container at least at the time of unloading and is transported to a target location along a pipe (2) using a progress- sive cavity pump (P2). The discharge of the nanofibrillar cellulose is ensured by ?? selecting the distance (L) of the suction side of the pump (P2) from the discharge point (3b) so short that the nanofibrillar cellulose flows from the container (3) by the effect of the pump suction， or ?? pressurizing the nanofibrillar cellulose in the container (3) to such a pressure (p) that it will flow at the selected distance (L) of the suction side from the discharge point by the common effect of the pressure of the nanofibrillar cellulose and the pump suction.

一种以粘性液体分散体形式输送纳米原纤化纤维素（nanofibrillar cellulose）的装置及方法。纳米原纤化纤维素从容器(3)的排料口(3b)卸料，该排料口至少在卸料时刻，相对于容器内纳米原纤化纤维素的物料容积而言为最低点位；物料通过单螺杆泵（progressive cavity pump）P2沿管道(2)输送至目标位置。纳米原纤化纤维素的卸料过程可通过以下两种方式保障：一是将泵吸料侧与排料口(3b)之间的距离(L)设置得足够短，使得纳米原纤化纤维素可在泵吸作用下从容器(3)中流出；二是对容器(3)内的纳米原纤化纤维素施加压力(p)，使得在泵吸侧与排料口的选定距离(L)下，借助纳米原纤化纤维素自身压力与泵吸作用的共同效果，使物料顺利流动。
