一种滚筒法钢渣处理装置 技术领域
本发明涉及热态冶金熔渣处理装置。 背景技术
现有滚筒法冶金渣处理装置是目前较先进炉渣处理设备之一， 具 有流程短、 投资少， 安全可靠、 能耗低的特点， 处理后的炉渣能直接 利用、 污染少。 滚筒法冶金渣处理技术及装置， 特别是垂直进料的双 腔式滚筒装置， 较好地克服了传统渣处理工艺和设备的不足， 不但流 程短、 投资少， 而且操作方便、 能耗低， 处理后的成品渣质量好。 现 有专利 CN1141401C公开了一种用于处理钢渣的 "双腔式滚筒钢渣处 理装置"。 参见图 1， 该装置通过托圈 16、 篦条 31和旋转端盖组成两 个相对开口的鼠笼式筒体， 其中， 篦条和托圈是通过螺栓联结在一起 构成框架的。 两个筒体开口侧之间设置有可同步转动的分流盘 9， 将 两个筒体分隔成相对独立的两个腔体， 分流盘旋转的力矩来自芯轴 6。 分流盘的下部是固定不动的固定环 12， 呈半圆环状， 起分隔两个腔体 的作用， 同时阻挡渣料 7和冷却体 8的泄漏。 筒体的正下方是集中排 料的出料漏斗 13。 四个托圈的下部呈一定角度安置有八组托轮装置
15， 将装置的旋转部分托起来。 固定罩壳 14 位于旋转筒体的外部， 起着密封作用。 运行时， 钢渣放流到漏斗 1 中， 落在分流盘 9上并被 分别导流到两个筒体内， 经冷却体 （钢球） 8 的冷却、 破碎， 当粒径 达到较小尺寸后， 由篦条间的缝隙漏出， 经出料漏斗 13 排出装置； 过程中产生的蒸汽由固定罩壳收集后经专设的烟罩、 烟囱排出。 该装 置实现了垂直进渣， 较完善地解决了高粘度渣的进料问题。 但不足之 处是： 滚筒为单层筒体结构， 渣料的冷却不充分， 易出现红渣。 支撑 装置多， 设备重量大； 下部空间有限， 维护和检修不方便。
此外， 在现有的双腔式滚筒法冶金渣处理装置中， 固定环位于旋 转着的分流盘下部， 筒体的中间， 该固定环包括基板和侧板， 侧板上 开有多个内凹坑， 基板和侧板组成 V形小室， V形小室内充满钢球和 确 认 本 渣料， 基板上开有下料孔， 该结构虽然保护了固定环， 但筒体转动时 阻力大， 进而影响了筒体运行和固定环的使用寿命。
再如图 8,9所示， 现有的滚筒法冶金渣处理装置用筒体呈圆台状， 锥体部分置于内筒体的外侧， 圆柱体部分沿圆周均布有抄板， 抄板沿 径向有一倾角 α。 经过内筒体处理后的渣料靠重力作用落到外筒体的 锥面内侧， 依靠锥体的倾斜面把渣料导入圆柱形筒体部分， 在抄板的 作用下， 把渣料抄送到出料溜槽， 送出装置。 该筒体的不足之处在于： 筒体为了把料排出去， 必须要有锥状， 即有倾角 α， α的大小满足渣 料的安息角， 一般为 45°， 这样从内筒体下来的渣料就会沿轴向输送 到出料溜槽的下部。 根据结构的几何关系， 外筒体直径等于内筒体直 径加上内筒体工艺宽度的 2倍， 这样导致筒体的外径非常庞大， 重量 重， 投资大。
另外， 参见图 12、 图 13， 现有的滚筒法冶金渣处理方法是： 渣 料从进渣口进入旋转着的内筒体内， 内筒体由篦条组成的鼠笼形筒 体， 筒体两端为端盖， 在惯性作用下渣料被抛到冷却体 （即钢球） 表 面， 然后在重力作用下渗入钢球与钢球间缝隙， 被冷却、 破碎， 再从 内筒体下部的篦条排出进入外筒体。 通常情况下， 随着内筒体的转动， 只有上表层和靠近内筒体 （下表层） 的钢球及渣料在摩擦力及重力作 用下沿图 13 中箭头所示轨迹进行运动， 中间类似腰子形范围内的钢 球远离内筒体， 受周围钢球的摩擦力较小， 运动范围小， 甚至不动， 无法参与正常的热量交换。 随着热渣料的下渗， 这部分钢球的温度迅 速升高， 却又得不到及时冷却， 失去正常的热量传递效果。 尤其是当 热渣料粘度较高时， 渣料向钢球间缝隙渗透的能力较弱， 大部分覆于 腰形钢球体的上表面， 形成 "渣壳"， 渣料与钢球接触面积小， 参与 冷却渣料的钢球只有腰形钢球体上表面的一层， 冷却效果差， 容易在 筒体内产生响爆现象， 碎化效果也很差， 容易导致红渣排出装置， 不 仅影响后序设备的使用寿命， 而且成品渣的性能差， 对直接利用也不 利。 发明内容
本发明的目的在于提供一种采用芯轴支撑的双腔式滚筒钢渣处理 装置， 降低设备重量， 减少成本， 同时增加下部检修、 维护空间。
本发明的进一步目的在于提供一种采用芯轴支撑的双腔式滚筒钢 渣处理装置， 该处理装置能延长渣料在装置内的冷却时间和冷却效 果， 提高成品渣的性能。
本发明再一个目的在于提供一种双腔式滚筒法冶金渣处理装置用 固定环， 它克服了现有固定环结构影响筒体转动的缺陷， 侧板表面光 滑， 对冷却介质和渣料摩擦阻力较小， 对筒体转动影响小， 且固定环 使用寿命长， 具有结构简单， 成本低的特点。 本发明还有一个目的在于提供了一种滚筒法冶金渣处理装置用筒 体， 它克服了现有的筒体体积大， 投资大的缺陷。 该筒体采用螺旋抄 板， 使筒体具备轴向输送渣料的能力， 减小筒体的直径， 降低设备的 投资。
本发明再有一个目的在于提供双腔式滚筒法冶金渣处理装置用的 抄手， 克服现有的内筒体内钢球与高粘度熔渣接触少的缺陷， 使高粘 度熔渣在筒体内能得到充分冷却和碎化。
根据本发明的一个方面， 提供了一种采用芯轴支撑的双腔式滚筒 钢渣处理装置， 包括左、 右筒体、 分流盘、 芯轴、 进料漏斗， 左、 右 筒体间置放分流盘且对着分流盘处为开口端， 分流盘上方装有进料漏 斗， 分流盘下方装有固定环， 芯轴固接左、 右筒体和分流盘， 其中， 在左、 右筒体外侧、 芯轴两端装有支撑用轴承。
较佳地， 左、 右筒体为内外两层， 内筒体由篦条构成， 篦条一端 通过支撑圈构成的插口固定在外筒体的端盖上， 篦条另一端与固接在 外筒体上的支撑圈相联接， 芯轴固接外筒体， 在一侧的外筒体外侧装 有传递力矩的齿圈， 齿圈与外筒体一端固接。
较佳地， 在内外筒体间装有螺旋抄板， 螺旋抄板固接在外筒体内 表面； 螺旋抄板轴线与外筒体轴线成一定角度， 该角度为 30~55度。 较佳地， 所述固定环相对左右筒体的两侧板之间设有呈放射状布 置的支撑筋板， 在固定环外围有固定罩壳， 固定环和固定罩壳被固定 于基础上。
与现有技术相比， 本发明在保持双筒体和垂直进料的基础上， 在 芯轴的两端增设支撑用轴承， 将设备的重量分担在这两个轴承座上； 取消了现有滚筒技术中必不可少的托轮装置和托圈， 大大减轻了设备 重量， 降低了制造成本， 又简化了下部构成， 腾出了大量供日常维护 和检修用的空间， 而且整个设备结构紧凑， 由于采用芯轴支撑， 轴承 能够实现良好的轴向定位， 解决了困扰滚筒设备的轴向窜动问题。
进一步地， 在内筒体的外围增设可同步旋转的外筒体， 并在外筒 体内设置了螺旋抄板， 螺旋抄板的轴与滚筒的轴线成一定的角度， 该 螺旋抄板使得外筒体内存有一定量的水， 强化了外筒体的冷却， 既延 长渣料在筒体内的冷却时间， 又保证成品渣能在设定的区域排出。
同时， 为防止固定环卡阻， 取消了固定环下部的母板， 左右两侧 板靠放射状筋板支撑， 使所有能进入固定环与分流盘间隙内的渣料都 能迅速顺利地排出， 同时还能有效的减少设备重量。 出料漏斗上部与 固定罩壳固接， 下部与渣料输送装置的接口连接。 本发明可有效的保 证各种形态的冶金渣 （液态渣、 玻璃态渣、 甚至小于 300mm 的固态 渣）顺利进入装置内； 渣料冷却充分， 成品渣性能稳定； 设备重量轻， 成本低； 检修、 维护空间大。 - 根据本发明另一方面， 本发明还提供了一种双腔式滚筒法冶金渣 处理装置用固定环， 包括基板、 侧板、 和筋板， 基板为大半圆形条板， 侧板为环形板， 侧板与基板的布置呈卜形， 两块侧板平行装在基板上， 并距基板侧面内收一段距离， 这段距离等于基板本身的宽度， 侧板内 侧装有筋板。
较佳地， 所述侧板安装在基板上的内收距离为 50 至 150厘米； 侧板安装位置是半圆环状， 呈后面高， 前面低。
与现有技术相比， 本发明的侧板表面光滑， 侧板安装在基板侧面 内收一段距离内， 让出的这段距离正是为了冷却体 （即钢球） 紧贴侧 板， 在筒体转动时不动或微动， 从而实现侧板不容易被磨损， 同时对 筒体的转动影响也较小的目的。 固定环呈半圆环结构， 与筒体和分流 盘间都保持一定的间隙， 这样既起着封闭渣料和工艺介质的作用， 又 保护了分流盘， 防止分流面免受渣料和工艺介质的直接磨损。 本发明 具有使用寿命长、 简体转动阻力低、 结构简单、 成本低的特点。
根据本发明的再一个方面， 提供了滚筒法冶金渣处理装置用筒体， 筒体内装有内筒体， 筒体内表面装有螺旋抄板， 抄板沿筒体内表面均 匀分布。
上述的滚筒法冶金渣处理装置用筒体， 所述抄板为平面或螺旋形 面。
与现有技术相比， 本发明的筒体采用螺旋抄板代替了原筒体的锥 面， 在保证正常出料的情况下， 将结构复杂的圆台状筒体简化为圆柱 状筒体， 减小筒体的直径， 优化装置的结构， 减轻装置的重量， 结构 简单， 降低了设备的造价。
根据本发明再有一个方面， 在内筒体内壁上安装有凸出的抄手。 较佳地， 所述内筒体篦条上安装有抄手， 抄手截面为 L 形或倒 Π 形， 钢球从 L形或倒 Π形抄手落下。
较佳地， 所述内筒体端盖上安装有抄手， 抄手的端部装有导向板， 抄手沿端盖中心呈放射状排列。
与现有技术相比， 本发明的内筒体篦条和端盖采用凸出的抄手， 将靠近内筒体表面的钢球抄起来， 通过篦条的抄手和端盖的抄手导向 板将钢球按照设定的方向和角度抛投落渣区域， 对高粘度熔渣形成的 渣堆或渣壳进行冲击、 破碎， 强化冷却。 同时， 由于抄手的作用， 内 筒体内靠近篦条和端盖的钢球和渣料被源源不断地带走， 附近的钢球 则不断补充进来， 结果原来相对 "静止"不动的腰形区域内的钢球和 渣料相对向下和向两侧运动， 参见图 14、 图 16 中箭头线， 从而消除 腰形 "死区"， 最大限度地发挥所有钢球的传热功能。 因此本发明的 处理方法具有实施容易， 结构简单， 成本低、 效果好的特点。 附图说明

参见图 2、 图 3 , —种滚筒钢渣处理装置， 包括左、 右筒体 2、 分 流盘 9、 芯轴 6、 进料漏斗 1， 左、 右筒体为内外两层。 左、 右外筒体 2分别与芯轴 6固接； 内筒体由篦条 3构成， 篦条 3—端通过支撑圈 18、 19构成的插口固定在外筒体 2的端盖上， 篦条 3另一端与固接在 外筒体 2上的支撑圈 11通过紧固件 10联接。 在内、 外筒体 3、 2之 间装有螺旋抄板 17， 螺旋抄板 17固接在外筒体 2 内表面， 螺旋抄板 17轴线与外筒体 2轴线成一定角度， 该角度为 35〜55度。 左、 右筒体 之间是分流盘 9， 分流盘 9与芯轴 6固接， 芯轴 6由装于左、 右筒体 外侧的轴承 4支撑， 芯轴 6的一端固接有传动齿圈 5， 传动齿圈 5位 于外筒体 2外侧。 在分流盘 9的下部设置有固定环 12， 固定环 12与 分流盘 9和内筒体 3分别形成一定的间隙配合， 固定环 12相对左右 筒体的两侧板之间设有呈放射状布置的支撑筋板， 固定环 12 下部为 空心， 固定环 12直接固定在基础上。 在固定环 12的外围设有固定罩 壳 14， 它与外筒体 2构成一定的间隙配合， 用以收集外筒体 2排出的 渣料和蒸汽， 固定罩壳 14也直接固定在基础上。 分流盘 9 的上部一 侧设有进料漏斗 1， 进料漏斗 1与分流盘 9形成一定的间隙配合， 直 接固定在基础上。 出料漏斗 13上部与固定罩壳 14固接， 下部与渣料 输送装置的接口连接。
在本发明中， 参见图 4一 7， 一种双腔式滚筒法冶金渣处理装置用 固定环 12， 包括基板 22、 侧板 20、 盖板 24和筋板 21。 基板 22呈框 架式结构， 上覆大半圆形条板， 保证了固定环 12的刚度； 基板 22的 两侧面覆有衬板 23， 通过螺栓与基板 22连在一起， 可方便拆装； 基 板 22上开有下料孔， 可及时的将分流盘 9面带下来的少量渣料排出 固定环 12。 侧板 20为环形板， 两块侧板 20平行装在基板 22上， 并 距基板 22侧面内收一段距离，该距离为 50至 150厘米，最佳为 80~90 厘米， 这样在筒体 2转动的过程中， 紧贴侧板 20 的冷却介质不动或 稍微转动， 形成一个相对紊动的介质自磨层， 起到保护固定环侧板 20 的作用。 侧板 20 内侧装有筋板 21， 便于支持侧板 20; 侧板 20两端 部装有盖板 24， 防止渣料落入固定环 12内。 这样基板 22、 侧板 20、 筋板 21和盖板 24形成了半密闭结构， 将左右两筒体 2分开。 同有基 板和侧板与工艺介质接触的表面都可以带有可拆卸的衬板。
参见图 5， 侧板 20安装位置是半圆环状， 呈后面高， 前面低。 因 为筒体 2的转动方向是由前向后， 这样可更有效地利用好固定环 12。
参见图 10、 图 11， 本发明的一种滚筒法冶金渣处理装置用筒体， 外筒体 2呈规则的圆柱状， 外筒体 2内有沿圆周均匀分布的抄板 17。 抄板 17不仅沿径向有一倾角 α， 而且沿轴向有一倾角 β， 抄板 17可 为平面或螺旋形面。 外筒体 2 内装有内筒体 3， 外筒体 2上装有出料 溜槽 25。经过内筒体 3处理后的渣料靠重力作用落到外筒体 2的内侧， 随着外筒体 2的旋转， 渣料在重力作用下沿抄板 17有一 β角的向下 分力， 通过该分力自动沿轴向滑动， 从内筒体 3 的垂直投影面区域滑 入出料溜槽 25的投影面上， 进入出料溜槽 25， 排出装置。
参见图 14、 图 15、 图 16， 本发明还提供了在内筒体 1 内壁上安 装有凸出的抄手 28， 抄手 28将内筒体 3内的钢球 8和渣料 7抄起， 内筒体 3旋转一定角度后， 钢球 8和渣料 7从内筒体 3上部的抄手 28 抛落， 落在内筒体 3下部的钢球 8和渣料 7上， 渣料 7被冲击和破碎， 并且靠近内筒体 3表面的钢球 8和渣料 7不断被抄手 28抄起， 促进 了钢球 8和渣料 7的搅拌和混合。
参见图 14， 图中示出了抄板 17的一个实施例， 即内筒体篦条 31 上安装有抄手 28， 抄手 28截面为 L形， L形抄手 28能引导钢球 8准 确落入需要落入的区域， 一般为渣料 7的落渣点， 落入的钢球 8对渣 料 7进行冲击、 破碎， 强化冷却。 同时也将靠近内筒体篦条 31 的钢 球 8和渣料 7抄起， 增加了钢球 8与渣料 7的搅拌和混合， 便于钢球 和渣料的热交换。 抄手 28可以是铸件， 也可以是焊接件， 更换方便。
参见图 15、 图 16， 内筒体端盖 26上安装有抄手 28， 抄手 28面 向端盖 26中心端装有导向板 27， 抄手 28沿端盖 26中心呈放射状排 列。 抄手 28的工作面为平直状态， 背面有加强作用的筋板。 导向板 27 呈 V字形， V字形坡度的大小以将钢球 8抛射到渣料 7落渣点为宜。 抄手 28和导向板 27可以是铸件， 也可以是焊接件， 更换方便。
