本发明筛笼 5中的筛网,在材质与结构上作了较大的改进。如图 3 所示:筛网的连接筋为 5条,筛条的厚度为 6. 5mm,宽度为 3. 05mm,其 两端的连接环各为 5个,使其比原筛网刚度增加;材质逸择上: 网采 用在尼龙 1010原料中加入 22. 3% 的玻璃纤维, 制成了增强尼龙筛 网, 提高了热变形温度,满足了料浆为近 60°C 的生产要求',同时增加 了耐磨性能。 此外筛网还可以用聚甲窿为原料,耐温可达 85。C以上。
为有利于筛下产品的排放,如图 1所示,筛下体 6为马蹄形,筛下 体 6上的筛下出口管由水平向下倾斜 45度。
本发明筛笼型旋流细筛的工作过程是由分解槽以一定的压力 ^氬 氣化铝料浆输送到该设备给料体 3上的给料口,以近似渐开线方向进 入给料体 3内,料浆沿圓筒筒壁作圆周运动,在惯性力作用下,粗、中颗 粒的离心力较大, 碰撞笼型筛网 5,中颗粒通过筛网,由筛下体 6外环 出口管排出,不能通过筛网的粗颗粒物料沿着筛下体 6内锥壁旋入圓 锥体 7,再由底流口 8排出,细颗粒离心力较小,在中心旋涡附近,受中 心旋涡影响向上运动,由溢流管排出。
本发明筛笼型旋流细筛是一种湿式细粒分级设备, 可用于拜尔法 砂状氣化 吕生产中的氳氣化铝分级, 粗煤泥回收,细煤泥分级,还可应 用于其它行业细粒物料的分鈒、浓缩等作业。该设备用于砂状氣化 吕生 产,能满足细粒附聚、粗粒粘结长大的二段分解工艺要求,可解决氳氣 化 吕粒度周期粗化。 细小交替出现的技术难关,使产品物理性质稳定, 分^出的粗粒产品小于 44μηι的粒级含量少,固含高;中粒级产品返回 分解槽作晶种,活化能力强;细粒级产品固含低。 该设备具有处理能力 大,分级效率高,设备体积小,工艺簡化、投資少,耗电省,筛.网寿命长, 更换方便等优点。
