Description

浓密机风水联动造浆系统及基于该系统的损坏喷嘴定位方法 技术领域
本发明涉及矿山充填采矿业中的尾砂浓密脱水工艺技术领域，具体涉及一种浓密机风水联动造浆系统，主要用于矿山充填高深锥浓密机内尾砂活化造浆放砂；本发明还涉及基于该系统的损坏喷嘴定位方法。
 背景技术
尾砂充填技术是上世纪80年代末发展起来的新型矿山充填技术，在矿山日益得到广泛应用。该技术的特点是以尾砂作为充填骨料，通过活化搅拌，在高浓度状态下输送到地下采场空区。该工艺可将分级粗尾砂、分级细尾砂甚至全部尾砂作为充填料充填至井下，无需建尾矿库，为无废开来奠定了基础。由于尾砂在充填料仓中沉淀为饱和砂，若使其顺利充填，必须进行浓度调节，使之流态化，即通过活化介质使尾砂失重、浆化，以便使其能顺利从料仓内流出，这种流态化工作是由充填喷管组件喷出的高压水和压缩空气来完成的。
现有的矿山充填砂仓的喷管座一般安装在充填料仓内的管路上，维修必须在充填料仓内完成，并且维修前必须将充填料仓内的尾砂清理干净，将喷管和管路全部暴露出来后，维修人员通过检修孔，进入充填料仓内才能进行维修。由于料仓内通风不畅，且无检修平台，存在维修人员缺氧、滑落等安全隐患。维修时间长，辅助工时高，工人劳动强度高。
有部分矿山采用外置喷嘴，但与内置喷嘴存在同样的检修不便问题，具体说，同一砂仓设有高度不等的大量喷嘴，每个喷嘴性能和使用状态各异。使用中会有部分喷嘴因过度磨损、喷嘴构件损坏或者保护套脱落等因素不再具有防倒流功效，导致尾砂倒灌，砂浆进入喷嘴以及造浆管内。这对这一问题，目前的做法是：每次造浆之前清理造浆管内的尾砂，这一措施的不足在于：第一、增加了操作程序和劳动量，降低了工作效率；第二、对于喷嘴内构件损坏导致喷嘴失效等情况仍无法解决，因而出现喷射点减少，造成尾砂放砂困难，浓度波动大，流量不稳定等现象发生，并且影响砂浆活化质量。如果喷嘴中复位弹簧因故障或者因疲劳无法复位，从喷嘴外表难于发现，需要逐个拆卸喷嘴检修，工作量非常巨大。
 技术问题
本发明所要解决的技术问题是，提供一种浓密机风水联动造浆系统及基于该系统的损坏喷嘴定位方法，第一、更加有效地对仓底尾砂进行活化，以避免板结，提升造浆浓度、流量的稳定性；第二、解决矿山尾砂充填造浆系统造浆喷嘴易磨损失效不能及时发现和更换难题，能够快速、精准定位损坏的造浆喷嘴，提高检修效率。
