概述 DESCRIPTION
LSL双螺旋挤浆机主要用于化学制浆黑液的高温、高浓、高效提取，尤其是麦草制浆的黑液提取，该系统密封性较好，浆料热损失小，黑液提取率高，所提取的黑液具有较高的温度和浓度，能为碱回收等黑液处理工序的节能增效创造有利的条件，同时，较高的黑液提取率降低了中段水的污染程度，减轻了后续工序的浆水处理负荷，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出浆口进入双螺旋挤浆机的进料口，通过双螺旋轴的旋转，纸浆由一端被推向另一端，在推进过程中由于双螺旋轴的螺距由大变小，纸浆在机内向前运动的过程中受到的挤压力不断增大，迫使其中的黑液被挤压出来并由滤孔排出，提取黑液后的浆料浓度达到38%以上，并经出料口排出，该设备结构简单，占地面积小，操作方便,使用可靠，是制浆造纸厂黑液提取的理想设备。
The LSL double helix press master mainly uses in the chemical pulping black liquor the high temperature, Gao Nong, the highly effective extraction, particularly the wheat straw pulping black liquor extraction, this system leak-proof quality is good, the pulp heat los is small, the black liquor extraction rate is high, withdraws the black liquor has the high temperature and the density, could for black liquor processing working procedure and so on alkali recycling energy conservation efficiency creation advantageous conditions, simultaneously, the high black liquor extraction rate reduce the center-section water pollution degree, reduced the subsequent handling starch processing load, its work process was the paper pulp by spurts the warehouse the discharge hole or the high practical knowledge strength pulp kneader Jiangkou enters the double helix press master's feed head, through double helix axis revolving,The paper pulp is pushed to by an end another end, in advancement process, because the double helix axis's pitch is small by the big change, the paper pulp in within the aircraft in the forward motion process receives the extrusion pressure to increase unceasingly, force black liquor is extruded and by filters the hole to discharge, after withdrawing the black liquor the pulp density achieves above 38%, and discharges after the discharge hole, this equipment structure is simple, the area is small, the ease of operation, the use is reliable, is the pulping paper mill black liquor extraction ideal equipment.
