Description

直线行波磁选机
技术领域
本发明涉及选矿设备，尤其是一种直线行波磁选机。
背景技术
迄今为止，磁力选矿多利用永磁固定磁场或电磁固定磁场，在磁场作用下，磁性矿粒(矿浆)受固定磁场磁力作用，向磁极运动，从而被吸附在非磁性材料做成的圆筒上，圆筒作旋转运动，把磁性物料与非磁性矿物分离，这种磁力选矿设备的缺点是结构复杂，运动部件和传动系统需经常维修。另外，因磁极固定，磁场亦固定，矿物在圆筒表面上只能做翻滚运动，分选效果不理想。
发明内容
本发明的目的就是提供一种结构简单、维修方便，可连续分选的直线行波磁选机。
本发明的直线行波磁选机，包括分选槽、精矿斗、尾矿斗，分选槽为方形结构，底部为矩形平面，分选槽的上部两端分别设有进料斗及冲选介质管，分选槽底面两端分别与精矿斗和尾矿斗连接，分选槽的底面上开有均匀分布的通孔，通孔与管道相连，行波磁场线圈设在分选槽下方，与分选槽固接。
本发明的直线行波磁选机工作原理是：矿浆由进料斗进入分选槽中，均匀撒落在分选槽下部矩形平面上，与此同时，行波磁场线圈导通三相电源，产生由左向右作行波运动的直线磁场，矿浆中的磁性物料(铁、钴镍、锰等)在行波磁场作用下，向精矿斗一端移动、团聚及翻滚，矿物在运动过程中，又受到冲选介质管中出来的逆方向的冲选介质冲刷，当磁场运动力大于逆行冲选介质的冲选力时，磁性矿物则向右方向移动并落入精矿斗中，从精矿斗排出。矿浆中的非磁性物料不受直线磁场影响，只受到冲选介质的冲洗，向左端移动进入尾矿斗中，从尾矿斗中排出。由于在行波磁场作用下，磁性矿粒易产生团聚，团聚时矿团中会夹带非磁性矿粒，这部分团聚的矿团可通过分选槽底部通孔中充入的水或气冲散，使结团的磁性物料与非磁性物料分离。
本发明的直线行波磁选机结构简单，由于没有运动部件，维修极为方便，它能连续给矿料，连续分选，连续排矿，同时，通过电磁调节或变频技术，可调节磁场力大小及磁场直线运动速度，实现不同磁性矿物、不同分选速度的分选作业。
附图说明
图1为本发明结构示意图。
