Description

一种模块化磁选设备机组
技术领域
本发明属于磁选设备， 具体涉及一种全新型的模块化磁选设备机组， 本发明尤其适用 于弱磁性矿富集环节的磁选。 背景技术
近年来随我国经济的不断发展而对铁矿、 锰矿、 钛矿等成品矿物的需求量大幅增加， 进而适用于金属矿物筛选的选矿设备及选矿方法得到迅猛发展。其中强磁类选矿设备得到 大量普遍性应用， 国内目前一般的强磁类设备均为单一独立设备， 粗放式开采中提高处理 量的方法即为增大设备型号或增加设备台数。
随着大批量且不科学的连续开采以及矿物资源的有限，导致易选的强磁性矿物资源越 来越少。 为了从不易磁选的弱磁性矿物资源中选出所需要的物质， 根据目前的设备性能情 况， 必须使用强磁类设备进行分选， 另外随着选厂规模的扩大， 选用设备大型化已成为主 流趋势。 为加大选厂的处理量， 必需增大设备型号或增加设备台数。 即使如此， 使用目前 的磁选设备也一直无法达到单台设备每小时干矿 300吨乃至以上处理量的要求。
此外，现有技术中的强磁选设备的最大规格型号已经达到了一般道路运输条件的限制 的临界值， 再加上加工设备的制约使这种无限扩大规格型号的作法无法实现。在一定生产 规模的选矿厂区中， 若想增加产量， 则只能增加选用设备的台数； 而在大的选矿厂中， 每 增加一台设备就需要多一分的维护、 管理支出， 并多一个故障点， 因此增加使用设备的台 数并不利于大型选矿厂的统一管理，所以现有技术的磁选设备越来越不适用于大型磁选矿 厂。 这种局限性， 对于弱磁性矿物资源分选尤其明显。
因此， 急需一种可适用于弱磁性矿物资源分选且处理量大的磁选设备。 发明内容 为克服现有技术的缺陷， 经过技术人员多次设计和研究， 提出一种模块化磁选设备机 组， 其是一种适用于弱磁性矿物资源分选且处理量大的磁选设备。通过对磁选设备的结构 从新设计， 使本发明的磁选设备不但适用于弱磁性矿物资源分选， 而且可以通过磁性组件 合理布局来提高分选效果，通过增加机组的模块单元数量来提高处理量的全新的一种磁选 设备。
依据本发明的技术方案， 提供了一种全新模块化磁选设备机组， 通过增加磁选设备机 组的模块单元数量来增大磁选设备的处理量，适用于所任何处理量要求的弱磁性矿分选富 积处理。
本发明所述的模块化磁选设备机组包括励磁线圈、 聚磁钢芯、 分选转盘、 磁性物料接 斗、 非磁物料排斗、 物料振荡器、 转盘冲洗水装置、 支架、 转盘驱动装置、 物料分流管、 磁性物料汇总斗和进料斗； 其中励磁线圈环绕于聚磁钢芯外侧， 分选转盘位于聚磁钢芯的 两个极头之间， 磁性物料接斗位于磁分选盘与励磁线圈之间， 非磁性物料排斗位于磁分选 盘和聚磁钢芯之下，物料振荡器位于非磁物料排斗一侧，转盘冲水装置位于磁分选盘上方， 分选转盘与转盘驱动装置相连并固定在聚磁钢芯一侧， 并在送入矿物料处设有物料分流 管， 矿物料经物料分流管后流入位于分选转盘内侧的聚磁钢芯之上的进料斗内， 磁性物料 接斗所流出的磁性物料汇总于磁性物料汇总斗； 所述模块化磁选设备机组由支架支撑。
优选地， 位于励磁线圈内侧的聚磁钢芯水平放置； 在励磁线圈通电时， 聚磁钢芯在励 磁线圈的激发下产生水平方向的背景磁场， 背景磁场的方向与聚磁钢芯的放置方向相同。
优选地， 分选转盘竖直安装于聚磁钢芯的两极头之间， 分选转盘上设有带尖齿的聚磁 板。
优选地，在物料振荡器的作用下，在分选区域中在分选转盘处上下方向振荡浆状物料。 优选地， 进料斗中设有一溢流板， 可以使物料在流出进料斗时能够均匀地为分选转盘 给料。
优选地， 磁性物料在流经分选区域时会吸附在分选转盘的聚磁板的尖齿齿尖之上， 之 后可随分选转盘的转出两聚磁钢芯之间的分选区域， 再转至转盘冲水装置处。 进一步地， 磁性物料随转盘转至机组顶部， 经顶部的冲水装置喷出的卸矿水冲洗后， 所有已分选出来的磁性物料流入磁性物料接斗中， 进而汇入磁性物料汇总斗中。
优选地， 所有的非磁性物料在经过分选转盘的聚磁板时不吸附， 直接流经分选转盘后 流入非磁性物料排斗后排出模块化磁选设备机组。
优选地， 以一个分选转盘与和其相邻的两个聚磁钢芯极头和相对应的两个励磁线圈及 磁性物料接斗和进料斗为一个模块单元，每套磁选设备机组采用多个相同模块单元组合而 成， 多个模块单元中的多个分选转盘通过轴连接， 非磁物料排斗为共用， 并通过同一个物 料振荡器对待选物料进行振荡。其中， 相邻的分选转盘之间的聚磁钢芯和相对应的两个励 磁线圈及磁性物料接斗和进料斗为共用或不共用。
使用本发明所述的技术方案， 从本质上改变了常规强磁选设备的整体结构， 不但解决 了现有设备大型化瓶颈的问题，还解决了大型化后的设备运输和一般道路高宽限制之间的 矛盾， 使单台设备可以通过增加机组的模块单元数量的方式无限的增大， 同时使处理量也 随之同比增加， 并使设备具有了更合理的分体运输的条件。 附图说明：

参照附图 1-3， 本发明实施例所述的模块化磁选设备机组适用于弱磁性矿物富集， 其 包括励磁线圈 1、 聚磁钢芯 2、 分选转盘 3、 磁性物料接斗 4、 非磁物料排斗 5、 物料振荡 器 6、 转盘冲洗水装置 7、 转盘驱动装置 9、 物料分流管 10、 磁性物料汇总斗 11、 进料斗 12；其中励磁线圈 1环绕于聚磁钢芯 2外侧，分选转盘 3位于聚磁钢芯 2的两个极头之间， 磁性物料接斗 4位于磁分选盘 3与励磁线圈 1之间， 非磁性物料排斗 5位于磁分选盘 3和 聚磁钢芯 2之下， 物料振荡器 6位于非磁物料排斗 5—侧， 转盘冲水装置 7位于磁分选盘 3上方， 分选转盘 3与转盘驱动装置 9相连并固定在聚磁钢芯 2—侧， 并在送入矿物料处 设有物料分流管 10， 矿物料经分流管 10后流入位于分选转盘 3内侧聚磁钢芯 2之上的进 料斗 12内， 磁性物料接斗 4所流出的磁性物料汇总于磁性物料汇总斗 11 ; 所述模块化磁 选设备机组由支架 8支撑。
在励磁线圈 1通电时聚磁钢芯 2在励磁线圈 1的激发下产生磁场的方向与聚磁钢芯 2 的放置方向相同的水平方向的背景磁场。 分选转盘 3竖直安装于聚磁钢芯的两极头之间， 分选转盘上设有带尖齿的聚磁板。浆状物料受物料振荡器 6的作用会在分选区域中的分选 转盘 3处发生上下方向的振荡。
此外， 进料斗 12中设有一溢流板， 可以使物料在流出进料斗 12时能够均匀的对分选 转盘 3给料。 磁性物料在流经分选区域时会吸附在分选转盘 3的聚磁板的尖齿齿尖之上， 之后可随分选转盘 3的转出两聚磁钢芯 2之间的分选区域， 再转至转盘冲水装置 7处。
进一步地， 磁性物料随转盘转至机组顶部， 顶部的冲水装置 7喷出的卸矿水冲洗后所 有已分选出来的磁性物料流入磁性物料接斗 4中， 进而汇入磁性物料汇总斗 11中。 所有 的非磁性物料在经过分选转盘 3的聚磁板时不吸附，直接流经分选转盘 3后流入非磁性物 料排斗 5后排出模块化磁选设备机组。
模块化磁选设备机组的模块化构成方式： 以一个分选转盘 3与和其相邻的两个聚磁钢 芯 2极头和相对应的两个励磁线圈 1及磁性物料接斗 4和进料斗 12为一个模块单元， 每 套磁选设备机组采用多个相同模块单元组合而成，多个模块单元中的多个分选转盘 3通过 轴连接，非磁物料排斗 5为共用，并通过同一个物料振荡器 6对待选物料进行振荡。其中， 相邻的分选转盘 3之间的聚磁钢芯和相对应的两个励磁线圈 1及磁性物料接斗 4和进料斗 12为共用或不共用。
为了进一步说明本发明的模块化磁选设备机组工业实用性及有益效果， 下面结合该模 块化磁选设备机组的工作原理， 对该设备做详细阐述：
励磁线圈 1环绕于聚磁钢芯 2外侧， 聚磁钢芯 2水平放置， 分选转盘 3位于两聚磁钢 芯极头之间，在励磁线圈 1通电时聚磁钢芯 2在励磁线圈 1的激发下产生的磁场的方向与 聚磁钢芯 2的放置方向相同的水平方向的背景磁场， 该磁场区域即为物料的分选区域， 该 区域的磁场方向与物料的流入和物料的振荡方向垂直。分选转盘 3竖直安装于两聚磁钢芯 极头之间， 转盘上设有带尖齿的聚磁板。 在水平方向的背景磁场的作用下， 分选转盘 3上 的聚磁板的尖齿齿尖处产生一个小范围的极强的磁场区域，磁性物料在此区域的磁场的作 用下会吸附在分选转盘 3的聚磁板的尖齿齿尖之上。在非磁性物料排斗 5—端设有物料振 荡器 6， 浆状物料受物料振荡器 6的作用会在分选区域中的分选转盘 3处发生上下方向的 振荡。 待分选物料由物料分流管 10分流后均匀流入各进料斗 12中。 进料斗 12中设有一 溢流板， 可以使物料在流出进料斗 12时能够均匀的对分选转盘 3给料， 从而实现稳定良 好的分选指标。
待分选物料流过进料斗 12经溢流后均匀给入到分选转盘 3后部的分选区域开始进行 物料分选。 待选物料在流经分选转盘 3时磁性物料被吸附在聚磁板的尖齿齿尖之上， 由于 磁场的方向为水平方向， 因此磁性物料在磁场力的作用下会形成水平方向的物料链， 并随 分选转盘 3—起在转动从而通过分选区域。
在通过分选区的过程中被分选的物料在物料振荡器 6的作用下发生上下方向的振荡， 在此种振荡下可充分的对已吸附在聚磁板的尖齿齿尖之上的磁性物料进行冲洗，进而减少 其中磁性与非磁物料的相互夹杂， 并且也有效的防止了转盘上聚磁板间的堵塞。
磁性物料吸附在分选转盘 3的聚磁板的尖齿齿尖之上， 之后可随分选转盘 3的转出 两聚磁钢芯 2之间的分选区域， 再转至设备上方的转盘冲水装置 7处。 经转盘冲水装置 7 喷出的卸矿水冲洗后， 所有已分选出来的磁性物料流入磁性物料接斗 4中， 进而汇入磁性 物料汇总斗 11中。 所有的非磁性物料在经过分选转盘 3的聚磁板时不吸附， 直接流经分 选转盘 3后流入非磁性物料排斗 5后排出机组。
综上所述， 已经清楚详细地描述了本发明的磁选设备机组。但是参考本发明的优选实 施例详细示出并描述了本发明， 但本领域普通的技术人员可以理解， 在不背离所附权利要 求定义的本发明的精神和范围的情况下，可以在形式和细节中做出各种各样的修改。另外， 本说明书中的实施方案是为了阐述说明技术方案，而不应当将保护范围具体限制至本发明 中的某个具体实施例。
