Description

一种用于硅渣的可调筛选系统 技术领域
本发明涉及硅渣的重复利用加工领域，具体涉及一种用于硅渣的可调筛选系统。
背景技术
硅渣一般是指原矿提炼之后的剩余部分，还含有一定量的硅。硅渣分很多种，工业硅渣，太阳能硅渣，半导体硅渣等等。硅渣可以用来回炉重新结晶、提纯、现在硅料紧缺，价格不菲。硅锰渣也叫硅锰冶炼渣，是冶炼硅锰合金时排放的一种工业废渣，其结构疏松，外观常为浅绿色的颗粒，由一些形状不规则的多孔非晶质颗粒组成。硅锰渣性脆易碎，通过破碎机可以将大块的硅锰渣破碎成小块，然后进入细碎机将粗碎后的物料进一步粉碎，确保进入料仓的物料能够达到单体解离的程度，然后通过振动给料机和皮带输送机均匀的将物料给入梯形跳汰机进行分选。破碎的主要目的在于打破连生体结构，跳汰的主要目的在于从硅锰渣中回收硅锰合金。硅锰渣和硅锰合金存在较大的比重差，通过跳汰机的重选作用可以将金属和废渣分离，获得纯净的合金和废渣，最后可以通过脱水筛的脱水作用分别将精矿和尾矿进行脱水。
目前的硅渣处理，大部分还是依靠人工选取的方式，在一定的粉碎条件下，通过人工选取的方式来选择纯度较高的硅块，这样做的优点是成本较低，但是效率非常差，而且硅渣的利用率也很低；而采用梯形跳汰机进行分选的方式，选出来的硅纯度低，成本也高，硅渣的利用率也很低。
基于现有技术的特点和产业结构，急需提出一种新的工艺和配套的设备来进行工业硅渣的重新利用，以改变硅行业的产业结构，优化产业结构配置，实现产业的升级。
发明内容
本发明的目的在于提供一种用于硅渣的可调筛选系统，用于新的硅渣重新利用的生产环节，实现硅渣的初步筛选。
本发明通过下述技术方案实现：
一种用于硅渣的可调筛选系统，包括两个封板，两个封板通过多个等高块固定连接成四周开口的框架，在框架底部的开口上设置有一个平板，平板的一端连接一个弧形板，还包括一个喷气嘴，所述喷气嘴通过管道连接至高压储气罐，还包括一个与平板配对的物料输送带。本发明是采用两个面积较大的封板作为主体的，通过多个等高块固定连接形成整体框架，该框架在使用状态下呈立方体结构，其两个封板处于竖直状态，框架的上方、下方、两侧均为开口结构，使用状态下，在框架底部的开口上设置有一个平板作为输入物料的存放地，在两个封板之间设置有一个弧形板，还包括一个喷气嘴，喷气嘴和弧形板分别位于平板的两侧，喷气嘴通过管道与高压储气罐连接，使用时，将已经经过粉碎的矿渣通过物料输送带输送至平板，开通连接喷气嘴的高压储气罐的气体管路，高压气体从喷气嘴快速喷射而出，将已经粉碎的矿渣从平板水平吹出，并进入到弧形板限制而成的弯曲轨道，开始做曲线运动，在这个过程中，由于较纯净的硅块、较纯净的废渣、硅块与废渣的混合物三者的密度不同，而受到的气体的推动力基本相同，可以在两个封板与弧形板构成的空间内做弧线运动，其形成的水平方向速度不同，造成其水平运动的距离不同，根据这个特性，可以将粉碎后的硅渣分成三个部分：较纯净的硅、较纯净的渣、硅渣混合物，如此，经过初步的粉碎和筛选可以完成部分硅的选取，得到的较纯净的硅可以直接用于硅的熔炼，得到的较纯净的渣直接舍去，得到的硅渣混合物用于进行下一次的粉碎，然后重复的分选，直至不能再粉碎，经过试验得知，在经过3至4次的粉碎和分选后，可以得到硅渣重重量约30％左右较为纯净的硅，得到40％ 左右较为纯净的渣，剩余的30％左右的硅渣混合物粉末，如此，通过本发明设备的运用，可以将人工筛选产出率的5％提升至30％，相对于梯形跳汰机进行分选的方式的20％产出率任然有大幅的提升，同时本发明结构相对于梯形跳汰机而言结构简单，可操作性强，大大降低了设备的投入成本；由于将硅渣分离形成较纯净的硅、较纯净的渣、硅渣混合物三个部分，通过设置两个或三个集料斗，将三个部分的物料通过集料斗进行集中处理，形成完整的生产系统。
所述弧形板平滑连接在平板的末端，并向喷气嘴方向弯曲延伸至最高点。具体的讲，弧形板的弧形弯曲方向决定了气流带动分选物料的运动方向，通过设置成向喷气嘴方向弯曲延伸的结构，可以大大缩短封板的长度，节约空间，当弧形板延伸至最高点后，也就限制了分选物料的上升距离，使得其高度可以控制，而顶部的开口和框架侧面的开口可以快速地将高压气体的压力向外扩散，降低两个封板之间的气压，使得物料能够完成自由落体运动。
在所述的框架下方至少设置有两个集料斗，集料斗与平板分别位于喷气嘴的两侧，在集料斗上方设置有位置可调的分料器。进一步讲，由于将硅渣分离形成较纯净的硅、较纯净的渣、硅渣混合物三个部分，因此，通过设置两个或三个集料斗，将三个部分的物料通过集料斗进行集中处理，形成完整的生产系统，通过在集料斗上方设置可以调节位置的分料器，分料器顶部向下逐渐加宽，形成横截面呈三角状的结构，其位置可以调节，便于适应不同粒径、风速的筛选，可以形成一机多用。
本发明与现有技术相比，具有如下的优点和有益效果：
1、本发明一种用于硅渣的可调筛选系统，高压气体从喷气嘴快速喷射而出，将已经粉碎的矿渣从平板水平吹出，并进入到弧形板限制而成的弯曲轨道，开始做曲线运动，在这个过程中，由于较纯净的硅块、较纯净的废渣、硅块与废 渣的混合物三者的密度不同，而受到的气体的推动力基本相同，可以在两个封板与弧形板构成的空间内做弧线运动，其形成的水平方向速度不同，造成其水平运动的距离不同，根据这个特性，可以将粉碎后的硅渣分成三个部分：较纯净的硅、较纯净的渣、硅渣混合物，如此，经过初步的粉碎和筛选可以完成部分硅的选取，得到的较纯净的硅可以直接用于硅的熔炼，得到的较纯净的渣直接舍去，得到的硅渣混合物用于进行下一次的粉碎，然后重复的分选，直至不能再粉碎，经过试验得知，在经过3至4次的粉碎和分选后，可以得到硅渣重重量约30％左右较为纯净的硅，得到40％左右较为纯净的渣，剩余的30％左右的硅渣混合物粉末，如此，通过本发明设备的运用，可以将人工筛选产出率的5％提升至30％，相对于梯形跳汰机进行分选的方式的20％产出率任然有大幅的提升，同时本发明结构相对于梯形跳汰机而言结构简单，可操作性强，大大降低了设备的投入成本；
2、本发明一种用于硅渣的可调筛选系统，弧形板北设置成向喷气嘴方向弯曲延伸的结构，可以大大缩短封板的长度，节约空间，当弧形板延伸至最高点后，也就限制了分选物料的上升距离，使得其高度可以控制，而顶部的开口和框架侧面的开口可以快速地将高压气体的压力向外扩散，降低两个封板之间的气压，使得物料能够完成自由落体运动；
3、本发明一种用于硅渣的可调筛选系统，通过设置两个或三个集料斗，将三个部分的物料通过集料斗进行集中处理，形成完整的生产系统，通过在集料斗上方设置可以调节位置的分料器，分料器顶部向下逐渐加宽，形成横截面呈三角状的结构，其位置可以调节，便于适应不同粒径、风速的筛选，可以形成一机多用。
