Description

一种含铁围岩多工艺柔性组产分流装置及其分流方法 技术领域
本发明涉及含铁围岩综合利用技术领域，具体为一种含铁围岩多工艺柔性组产分流装置及其分流方法。

随着钢铁工业的迅猛发展，铁矿产能不断提高，矿山剥采比逐年增大，剥离的含铁围岩不断增加将含铁围岩大量堆积于排土场，不仅占用大量的土地资源，破坏环境；而且每年要投入大量的资金进行治理。近年来，有少数矿山企业在其综合利用方面进行了积极地探索与实践，大多数都是采用半连续剥岩工艺对含铁围岩进行破碎、干选回收部分可利用的磁铁矿，来降低排岩量。针对一些含闪长玢岩及花岗闪长玢岩含量高的含铁围岩，不仅可回收磁铁矿，同时可以回收余下的围岩作为建筑石材使用，最大化实现含铁围岩的综合利用。不仅增加了采矿效益，同时最大化的降低排土环保治理的压力与成本。
目前就露天采场采用半连续工艺对含铁围岩综合利用的生产线工艺来说还是比较粗放，尤其在首道粗碎干选工艺来说，生产工艺简单，无法及时应对采场原料的多变性，生产系统设备突发性情况造成的生产停滞及产品质量问题。虽然有些生产工艺通过翻板阀调控可以实现一些并联系统的切换，但实现不了在线调控且切换系统操作麻烦、劳动强度高。

    S2、由矿用汽车运输至采场内部的原料仓(2.1)通过棒条给料机(2.3)振动给料，小粒度的物料经筛孔进入围岩转运皮带(2.4)；大粒度的物料经振动送至颚式破碎机(2.2)破碎之合格粒度送至围岩转运皮带(2.4)；
    S3、将物料送至干磁机(2.5)进行大块干选，干选出的物料经分选漏斗(2.6)进行分选分流，其中分流工艺如下：
    S31、排岩工艺，分流闸板阀关闭：磁铁矿送至粗精矿转运皮带(2.8)运至Ⅱ段干磁选系统(2.12)，围岩分选至排岩可逆皮带(2.7)反转运至排 岩皮带(2.10)至排土场(2.15)排卸；
    S32、排土工艺I，分流闸板阀打开到位，排岩可逆皮带停止：磁铁矿送至粗精矿转运皮带(2.8)运至Ⅱ段干磁选系统(2.12)，围岩经排岩皮带(2.11)至围岩1#加工系统(2.13)排卸；
    S33、排土工艺Ⅱ，分流闸板阀关闭：磁铁矿送至粗精矿转运皮带(2.8)运至Ⅱ段干磁选系统(2.12)，围岩分选至排岩可逆皮带(2.7)正转运至排岩皮带(2.9)至围岩2#加工系统(2.14)排卸；
    S34、全系列工艺：磁铁矿送至粗精矿转运皮带(2.8)运至Ⅱ段干磁选系统(2.12)，围岩通过分流闸板的提升下降来调节排岩皮带(2.9)与排岩皮带(2.12)的运输量；
    S4、围岩至分选漏斗后，磁铁矿与围岩通过分矿器(4.7)进行分流；围岩通过安置于门型架(5.5)上的电动葫芦(5.4)，卷拉安置于闸板滑道(5.3)内的分矿闸板(5.1)的提升和下降来实现分流与关闭。
