专利号：200730016529.3

XSJ型双螺旋挤浆机，主要用于造纸制浆的黑液提取。其工作过程是纸浆由喷放仓的出料口或高浓水力碎浆机的以及经初步浓缩的浆料出浆口进入该双螺旋挤浆机的进料口，通过左、右螺旋轴的反向旋转，纸浆由一端被推向另一端。同时，由于左右螺旋轴的螺距由大变小和螺旋轴底径由细变粗，故纸浆在运动中受到连续的挤压，从而使黑液通过筛板孔眼挤出，被挤干的浆料则经出料口排出。 本设备结构简单，占地面积小，操作方便，使用可靠。是制浆造纸厂黑液综合利用理想的提取设备。 本机主要由螺旋轴、机座、齿轮、进浆口、筛鼓、筛板、减速器、联轴器、电动机等组成。 本机适用于木、竹、蔗渣、麦草、芦苇等为原料的纸浆黑液提取，同时也可用于废纸脱墨浆的黑液提取，本机如多台串联，则黑液提取效果更好。

Double Helix crowded XSJ-pulp, paper pulp for the extraction of black liquor. Its work is the process of spraying by the pulp put out the warehouse I expected or high water concentration pulper, as well as the initial concentration of the pulp slurry into the mouth of the double helix squeeze machine feed the population through the right and left of the screw shaft Reverse spin, by the end of the pulp to be on the other side. At the same time, due to spiral around the pitch axis and the small change by the end of screw shaft diameter from Biancu fine, the pulp in motion by the continuous extrusion, so that the black hole through the plate out, the slurry Jigan After a while I expected to discharge. The device structure is simple, small footprint, easy to use and reliable. Pulp and paper mill black liquor is the ideal utilization of the extraction equipment. Local spiral from the main shaft, base, gear, pulp into the mouth, drum sieve, sieve, reducer, coupling, electrical components and so on. Local applied to wood, bamboo, bagasse, wheat straw, reeds, and other raw materials for pulp extraction of black liquor, as well as DIP can be used to extract the black liquor, such as the local multiple series, the extraction of black liquor better .
