Description

一种破磨装置
技术领域 本发明涉及矿石等物料破碎和粉磨的技术，特 一种超重力冠量 破磨装置。 背景技术 破碎和粉磨技术作为世界上最古老、最传统的工艺已存在了几千 年的历史， 随着工业革命的发展， 特别是工业革命后选矿业的发展， 极大地推动了破碎和粉磨工艺及设备的发展与进步。破碎和粉磨到目 前还没有一个准确的定义来介定物料的颗粒尺寸变化在什么阶段叫 破碎、什么阶段叫粉磨。 总之， 破碎工艺过程比表面积增加慢， 粉磨 工艺过程比表面积增加快。我们所研制的超重力冠量破磨机技术，其 原理为设备在运行时冠入超重力的能量后，使物料破碎和粉磨同步完 成， 达到破碎、 细碎、 细粉、微粉的可控效果， 是具有变革意义的能 量与物料转换新方式。
由于需要破碎和粉磨的物料太多，品种复杂，成分和结构也不同， 所以各种各样的破碎机、粉磨机应运而生，但一般破碎只能将物料破 碎到一定的粒状 (约 3mm以上)，若再用破碎机破碎成粉末，效率明显 降低， 磨损明显加重， 所以需要粉末时就要用粉磨工艺来处理， 此时 所用的设备就是粉磨设备， 因此形成了破碎与粉磨两种机型的区分。
为了衡量破碎和粉磨效率高低， 出现了功指数的概念，功指数的 单位是 kw · h/t, 即粉磨 It矿物所消耗的能量， 该指标决定了每一 个破碎和粉磨系统是否成功的关键。另外， 能量与物料的转换还有一 个重要指标为细度， 为了表达物料的细度， 用两个常用指标来衡量， 即网目数和比表面积， 网目数和比表面积越大， 物料越细。
目前大型的破碎、 粉磨设备主要用在金属矿工业、水泥工业、 电 力工业、化工工业、冶金球团工业和非金属矿工业等行业。大多数的 破碎、 粉磨设备存在耗能高、 磨损大、产量低、 环境污染严重、耐用 性差等问题， 故行业内综合能耗指标高， 严重影响了企业的综合经济 效益。 发明内容 本发明的目的在于提供一种超重力冠量破磨装置， 以降低能耗、 提高产量。
为了实现上述目的， 本发明的解决方案是：
超重力冠量破磨装置， 由外转盘和内转盘套置而成， 外转盘、 内 转盘与物料的进料口连通，内转盘的侧壁上开设连通外转盘和内转盘 的通孔，外转盘和内转盘中对应通孔的位置相对设有承接物料的承接 板，外转盘和内转盘由电机带动旋转，外转盘和内转盘的转动方向相 反，外转盘的侧壁上开设出料口，物料由进料口进入内转盘和外转盘， 借助外转盘和内转盘的旋转而相对甩出、通过内转盘的通孔后相互碰 撞实现破碎和粉磨， 形成的细料由外转盘侧壁的出料口甩出。
上述内转盘的中心开口接至物料的进料口，物料经由进料口、 内 转盘的中心开口进入内转盘，再由内转盘经内转盘侧壁的通孔进入外 转盘。
上述承接板呈折板状。
上述承接板的边沿安装可拆卸式活动块。
上述外转盘和内转盘分别由一台电机带动旋转。
上述外转盘和内转盘的转轴上设有惯性配重轮。
上述内转盘由两个相对设置的环形板和复数个承接板组成， 复 数个承接板相互间隔设置在两个环形板之间，两个环形板固定连接在 承接板的两端，其转轴穿过第一环形板的中孔固定在第二环形板的内 侧， 物料由第一环形板的中孔与转轴之间的间隙进入内转盘；外转盘 也由两个相对设置的环形板和复数个承接板组成， 复数个承接板相 互间隔设置在两个环形板之间，两个环形板固定连接在承接板的两端， 其转轴固定在第二环形板的外侧；整个内转盘穿过外转盘第一环形板 的中孔， 套置在外转盘中。
采用上述结构后，本发明通过冠入超重力能量， 使物料与物料高 速对撞， 瞬间达到破碎、 细碎、 细粉、 微粉， 其具有如下技术优点- 一、 由物料的自身重量对物料以冠入超重力能量，利用超重力能 量对撞的原理， 使得发射后的物料堆撞击产生效应，在本机内瞬间达 到破碎、 细碎、 细粉、 微粉同步完成。
二、破碎和粉磨过程中在很小的范围内瞬间完成，其物料进出时 间仅为 3秒， 单台磨机产量可达 50〜80T/h， 设备的重量只及同产量 球磨机的 1/10、 体积只有球磨机的 1/6， 设备体积小， 研磨效率高， 产量提高。
三、利用超重力能量对撞的原理， 使得粉磨过程中可大量降低能 耗。 以钢渣破碎粉磨为例， 430 m2/kg以上的比表面积细粉， 吨耗电 <15度， 而同产量球磨机吨耗电为 >90度， 国外最先进的立式磨为 附图说明 图 1是本发明的正视外观图；
图 2是本发明的侧视剖示图；
图 3是本发明的原理示意图。 具体实施方式 如图 1、 2所示， 是本发明揭示的超重力冠量破磨装置， 由外转 盘 1和内转盘 2套置而成。外转盘 1和内转盘 2的作用是容纳、承接 物料， 并提供物料旋转发射的动力， 本文图示了外转盘 1和内转盘 2 的具体结构 （配合图 2、 3所示） ： 内转盘 2由两个相对设置的环形 板 21、 22和复数个承接板 4组成， 复数个承接板 4相互间隔设置在 两个环形板 21、 22之间，两个环形板 21、 22固定连接在承接板 4的 两端，其转轴 6穿过第一环形板 22的中孔固定在第二环形板 21的内 侧； 外转盘 1也由两个相对设置的环形板 11、 12和复数个承接板 4 组成， 复数个承接板 4相互间隔设置在两个环形板 11、 12之间，两个 环形板 11、 12固定连接在承接板 4的两端，其转轴 5固定在第二环形 板 11的外侧；整个内转盘 2穿过外转盘 1第一环形板 12的中孔，套 置在外转盘 1中。
外转盘 1和内转盘 2由电机（图中未示出）带动旋转， 且外转盘 1和内转盘 2的转动方向相反。 为了便于调节转速， 外转盘 1和内转 盘 2分别由一台电机带动旋转为佳。为了减少噪音， 外转盘 1和内转 盘 2的转轴 5、 6上还设有惯性配重轮（图中未示出） ， 使整机能稳 定、 平衡的工作， 全机工作环境噪音低于 75分贝。
外转盘 1、 内转盘 2与物料的进料口 3连通。 具体可将内转盘的 2中心开口接至物料的进料口 3， 使物料经由进料口 3、 内转盘 2的 中心开口进入内转盘 2 (图中所示物料是从进料口 3经由内转盘 2第 一环形板 22的中孔与转轴 6之间的间隙进入内转盘 2) ， 内转盘 2 的侧壁上开设连通外转盘 1和内转盘 2的通孔 20， 此通孔 20也可直 接由内转盘 2中承接板 4的间隙形成，再由内转盘 2经其侧壁的通孔 20进入外转盘 1。
承接物料的承接板 4对应通孔 20的位置相对设在外转盘 1和内 转盘 2中。配合图 3所示， 为了更好地承接、堆放物料、 降低发射后 的物料撞击机体而造成的磨损程度，承接板 4设计呈折板状。在研磨 时，承接板 4的边沿最易受发射后的物料重撞而损坏， 为了避免整个 承接板 4更换而成本太高， 承接板 4的边沿安装可拆卸式活动块 41， 使研磨重撞受损后， 只需局部更换即可。如此， 可彻底解决了历史上 粉磨行业研磨体介质消耗严重的问题。
外转盘 1的侧壁上开设出料口 10， 此出料口 10也可直接由外转 盘 1中承接板 4的间隙形成。
本发明使用时， 物料由进料口 3进入内转盘 2和外转盘 1 , 借助 外转盘 1和内转盘 2的旋转而相对甩出， 通过内转盘 2的通孔 20后 相互碰撞实现破碎和粉磨，形成的细料由外转盘 1侧壁的出料口 1甩 出。 本发明由外转盘 1、 内转盘 2的大小、 通孔 20的多少和间距可 决定研磨产量的大小并调整碎度和细度。本发明可根据物料软硬程度 来调整承接板 4、可拆卸式活动块 41，使超硬物料不影响装置易损件 的损耗。
