Description

一种用于环冷机台车的支承梁
本申请要求于 2007 年 9 月 3 日提交中国专利局、 申请号为 200710035673.0、 发明名称为"一种用于环冷机台车的支撑梁结构 "的中国专利 申请的优先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明属于用于冶金矿山行业中对烧结球团矿进行冷却作业的鼓风环式 冷却机领域， 具体涉及一种环冷机台车的支承梁。
背景技术
参见图 1 , 现有环冷机台车支撑梁结构图。 环冷机台车的支承梁， 用于支 撑台车。 台车支撑梁和篦板 103支撑所述台车运送的物料。 为了防止台车卸料 时， 支撑梁上部物料的堆积， 现有环冷机台车支撑梁采用三角梁结构。
现有环冷机作匀速圆周运动， 经过装料区 (数个台车面积） 时， 通过给料 溜槽均匀在台车上布料。装料后台车经过鼓风冷却区，冷风从下部风箱向上鼓， 经过篦板层 103 , 与台车篦板层 103上热烧结矿进行热交换后， 通过烟囱或直 接排往大气。 经约 1 小时时间热烧结矿基本冷却后， 台车经过卸料区 (数个台 车面积） ， 台车车轮 104沿卸料曲轵运动， 使得台车体 105以球铰 106为中心 做翻转运动， 此时篦板 103向下倾斜， 将篦板 103上的物料卸下。 同时由于三 角梁 102的两个侧板的存在，三角梁 102上的物料可以沿侧板滑落， 实现将烧 结矿卸入卸料溜槽， 完成冷却过程。 然后台车车轮 104 沿曲轨上升， 台车体 105复位后再进入装料区装料， 周而复始。
现有环冷机台车支撑梁的三角梁包括两个侧板 102b和一个底板 102a。 为 了保证支撑梁的良好支撑 , 所述支撑梁的三个板均使用盲板。
当环冷机台车工作时， 台车的篦板 103及支撑梁的两个侧板 102b上装满 矿料 104， 冷风从台车篦板 103下强制鼓入矿料层， 与矿料进行热交换， 从而 起到冷却矿料的作用。 由于风总是会沿阻力最小， 途径距离最短的区域通过。 冷风从台车篦板 103下强制鼓入矿料层， 冷风从三角梁的两侧 102b经过， 在 与矿料进行热交换后，从料层顶面排入大气。 由于组成三角梁的三个板均为盲 板， 三角梁底边投影面的上方 B 区域就只有少量甚至没有冷风进入， 形成了 矿料冷却死区。 发明内容
本发明的目的是针对现有技术的不足，提供一种环冷机台车的支承梁， 用 于改善支承梁上方矿料冷却效果。
本发明目的是通过以下技术方案实现的：
一种环冷机台车支承梁， 用于支撑环冷机台车， 所述支撑梁包括矩形梁和 位于所述矩形梁上的三角梁。
所述矩形梁的上翼板向两边延伸加宽作为所述三角梁底板，所述矩形梁的 上翼板向两边延伸加宽部分设置有通风孔，与所述三角梁底板相邻接的两个三 角梁侧板设置有若干通孔。
优选地，所述通孔的横截面形状和面积根据环冷机台车所冷却的矿料尺寸 确定；满足所述通孔的横截面面积小于所述矿料相对于所述通孔所在三角梁侧 板的投影面积。
优选地，所述通孔的横截面面积大于所述矿料相对于所述通孔所在三角梁 侧板的投影面积， 所述通孔内安装有与所述三角梁侧板同材质的篦条。

优选地 , 所述通风孔横截面积大于或等于每个所述通孔横截面积。
优选地， 所述通孔采用相同或者不同的形状。
优选地，所述矩形梁的上翼板向两边延伸加宽部分均设置有至少一个通风 孔。
优选地，所述矩形梁的上翼板一侧延伸加宽部分设置的各个通风孔相互独 立或相连通。
优选地， 各个所述通风孔横截面为圆形或三角形或其他多边形。
本发明环冷机台车支承梁包括矩形梁和位于所述矩形梁上的三角梁。所述 矩形梁的上翼板向两边延伸加宽形成所述三角梁底板，并且所述矩形梁的上翼 板向两边延伸加宽部分设置有通风孔， 冷风可以通过通风孔进入到三角梁内 部。 由于与所述三角梁底板相邻接的两个三角梁侧板设置有若干通孔，此时进 入三角梁内的冷风就可以通过这些通孔进入到图 1 中的 B区， 从而冷却了 B 区的矿料， 改善支承梁上方矿料的冷却效果。

具体实施方式
本发明提供一种环冷机台车的支承梁， 用于改善支承梁上方矿料冷却效 果。
为了更清楚地说明本发明所述环冷机台车支撑梁的结构和工作原理，下面 结合附图具体说明。
参见图 2和图 3 , 图 2为本发明实施例所述环冷机台车支撑梁的结构图； 图 3为图 2所示 I部分放大图。
本发明实施例所述环冷机台车支撑梁用于支撑环冷机台车。所述环冷机台 车支撑梁包括矩形梁 1和位于所述矩形梁 1上的三角梁 2。
所述矩形梁 1的上翼板向两边延伸加宽形成所述三角梁底板 21 , 且所述 矩形梁 1的上翼板向两边延伸加宽部分设置有通风孔 21a。 三角梁底板 21两 侧与用于通风的篦板 3相邻接。
所述三角梁底板 21相邻接的两个三角梁侧板 22设置有若干通孔 22a。 通 孔 22a横截面具体可以为圆形， 为了防止矿料 4从通孔 22a漏掉， 通孔 22a直 径需要满足小于矿料 4颗粒的最小外径或最小外形尺寸。
4尺寸即矿料的颗粒大小确定。 通孔 22a需要满足通孔 22a的横截面面积小于 所述矿料 4相对于所述通孔 22a所在三角梁侧板 22的投影面积。
通孔 22a还可以采用三角形、 椭圆形、 四边形或者多边形的形状。 为了防 止矿料 4从通孔 22a漏掉，通孔 22a内切圆的直径需要满足小于矿料 4颗粒的 最小外径或最小外形尺寸。
本发明环冷机台车支承梁包括矩形梁 1和位于所述矩形梁 1上的三角梁 2。 所述矩形梁 1的上翼板向两边延伸加宽形成所述三角梁底板 21 , 并且所述 矩形梁的上翼板向两边延伸加宽部分设置有通风孔 21a, 冷风通过篦板 3进入 矿料的同时，也可以通过通风孔进入到三角梁内部。 由于与所述三角梁底板相 邻接的两个三角梁侧板设置有若干通孔，此时进入三角梁内的冷风就可以通过 这些通孔进入到图 2中的 B区， 冷却 B区的矿料从而改善了支承梁上方矿料 的冷却效果。 本发明环冷机台车支承梁可以消除冷却死区即 B区。
为了更清楚地说明本发明实施例所述环冷机台车支撑梁与整个环冷机台 车的位置关系， 下面结合图 4至图 6进行具体说明。
参见图 4至图 6,图 4为本发明所述环冷机台车支撑梁第二实施例俯视图； 图 5为图 4所示 A-A向剖视图； 图 6为图 5所示 C-C向剖视图。
环冷机包括多个环冷机台车 100， 上述多个环冷机台车 100依次、 等距、 且同心布置，一起沿顺时针（图 4所示为顺时针方向转动）或逆时针同速转动。
本发明所述环冷机台车支撑梁第二实施例相对第一实施例的区别在于，所 述三角梁侧板 22上的通孔为相互平行的矩形。
为了保证支承梁上方矿料更好的冷却效果，本发明第二实施例所述环冷机 台车支撑梁的三角梁侧板 22包括三组通孔组， 每组通孔组包括多个相互平行 或者近似平行的矩形通孔 22b, 且每个矩形通孔 22b尺寸可以相同。
矩形通孔 22b的矩形长边可以平行于支撑梁所在环冷机台车 100与所述环 冷机中心的连线， 也可以与所述连线有一定的夹角。
为了更好地保证矿料的冷却效果，每个矩形的长边可以远大于短边，且短 边的长度小于矿料 4颗粒的最小外径或最小外形尺寸。
本发明第二实施例所述环冷机台车支承梁的矩形梁 1 的上翼板向两边延 伸加宽形成所述三角梁底板 21 , 并且所述矩形梁的上翼板向两边延伸加宽部 分设置有通风孔 21a。 冷风通道 200送入的冷风一部分通过篦板 3进入矿料， 另一部分通过通风孔 21a进入到三角梁 2内部。 由于与所述三角梁底板 21相 邻接的两个三角梁侧板 22设置有三组通孔组， 每个通孔组又包括多个相互平 行的矩形通孔 22b， 此时进入三角梁 2内的冷风就可以通过这些相互平行或近 似平行的矩形通孔 22b进入到支撑梁上方的矿料中冷却矿料，有效地增加了透 风面积， 从而改善了支承梁上方矿料的冷却效果。 在增大三角梁侧板 22的通风面之后， 单位面积风量减少， 平均风速有所 降低， 由于矿料层的阻力按风速的 1.67次方成正比的降低， 即（ = ^167 )。 在 冷风通道 200提供冷风能力不变的情况下 （即全压值不变）， 阻力降低， 风机 提供的风量就会相应增大。 由于风量的增大， 矿料就会得到更好的冷却。
由于篦板 3和支撑梁均有冷风通过，使得矿料层内部及矿料层表面的风速 变得更加均匀， 因此扬灰现象也相应地减少。
当然， 本发明实施例所述三角梁侧板 22也包括两组或者多组通孔组， 每 个通孔组也可以包括等距或不等距分布的矩形通孔 22b或其他形状的通孔，而 且每个通孔的尺寸可以相同也可以不同。
为了便于三角梁侧板 22的加工， 还可以采用多个子板依次安装组合构成 具有间隙或者通孔的三角梁侧板 22。
下面结合图 6具体说明台车卸料的过程。
台车的车轮 100a沿着预设的环形轨道（图中未示出）运动， 当某个台车 运动到需要卸料的位置时， 该台车的车轮 100a沿着轨道向下运动， 台车在车 轮 100a的带动下， 沿着固定在支撑梁上的转轴 300或者铰链转动， 从而带动 该台车上的篦板 3向下运动，实现卸料。由于支撑梁支撑物料的部分为三角梁， 由于三角梁两个侧板 22的存在， 三角梁上的物料可以沿右侧的侧板 22滑落， 实现卸料。 当相邻的下一个台车运行到卸料位置时，上一个台车的三角梁左侧 的侧板上的物料就会随着篦板 3的下落实现卸料。
参见图 7, 该图为本发明所述环冷机台车支撑梁第三实施例结构图。
本发明所述环冷机台车支撑梁第三实施例相对第一和第二实施例的区别 在于， 三角梁侧板 22包括多个子板， 子板之间依次固定安装或可拆卸地安装 在一起， 并且相邻两个子板之间具有间隙或者通孔， 从而保证冷风顺利通过。
本发明第三实施例所述环冷机台车支撑梁包括大小相同的多块子板，所子 板可以采用钢板， 相邻两块钢板之间通过至少两个篦条 25或者钢条焊接。 为 了进一步地改善冷却效果， 所述篦条 25或者钢条采用等距安装。
所述篦条 25或者钢条之间的间隔需要小于矿料 4的颗粒外径， 以防止矿 料 4从相邻两块钢板之间掉落。
本发明第三实施例所述环冷机台车支承梁的矩形梁 1 的上翼板向两边延 伸加宽部分设置有通风孔 21a， 冷风通道 200送入的冷风一部分通过篦板 3进 入矿料， 另一部分通过通风孔 21a进入到三角梁 2内部。 由于与所述三角梁底 板 21相邻接的两个三角梁侧板 22设置有间隙或者通孔， 此时进入三角梁 2 内的冷风就可以通过这些间隙或者通孔， 进入到支撑梁上方的矿料中冷却矿 料， 有效地增加了透风面积， 从而改善了支承梁上方矿料的冷却效果。
由于三角梁侧板 22上的间隙或者通孔增大了三角梁侧板 22的通风面积， 也就是扩充了整个环冷机的冷却面积， 因此单位面积风量减少， 平均风速有所 降低。 矿料层的阻力按风速的 1.67次方成正比的降低， 即（ = ^167 )。 在冷风 通道 200提供冷风能力不变的情况下 （即全压值不变）， 阻力降低， 风机提供 的风量就会相应增大。 由于风量的增大， 矿料就会得到更好地冷却。
由于篦板 3和支撑梁均有冷风通过，使得矿料层内部及矿料层表面的风速 变得更加均匀， 因此扬灰现象也相应地减少， 改善了周边环境。
本发明实施例所述环冷机台车支撑梁的三角梁侧板 22也可以为一整体的 钢板， 在所述钢板上开设矩形通孔， 然后在矩形通孔内焊接或者安装篦条， 从 而保证三角梁侧板 22最终形成的通孔可以防止矿料的泄漏。
本发明所述支撑梁可以按照水密封环冷机的规格大小确定支撑梁的各部 结构尺寸， 首先要根据台车 200规格高度确定矩形梁的高度，再确定三角梁底 板 21宽度和矩形梁的宽度， 最后按照完全卸料要求（矿料安息角）确定三角 梁侧板的投影高度。
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发 明的精神和原则之内所作的任何修改、等同替换和改进等， 均应包含在本发明 的保护范围之内。
