Description

砧板式梳状剪刃碎料装置
【技术领域】
本发明涉及一种与破碎机配套使用的再次碎料装置， 特别是一种适用于双齿辊式破碎 机的砧板式梳状剪刃碎料装置， 也可用于其它齿辊式破碎机对柔性物料的再次碎料。 【背景技术】
目前， 随着破碎技术的发展和适应对被破碎物料的排料粒度和作业效率的要求， 各种 破碎设备相继面世。 近年来国民的环保意识不断加强及国内多家生物电厂的上马， 使原本 废弃的农副产品得到开发和充分利用， 但传统的双齿辊式破碎机由于破碎行程短， 物料不 能被一次破碎成合格的粒度， 特别是对柔性物料如秸秆、 棉秆、 果木枝条、 树根树皮、 苷 蔗叶等的破碎， 根本不能满足生物电厂对破碎物料的出料粒度要求， 这也是多年来困扰生 物质电厂发展的瓶颈之一。 本发明人针对前述问题曾先后设计出公开号为 CN101185910A 的 "枝丫材专用破碎机"和公开号为 CN201143448 的 "四功能双齿辊破碎机"， 它们专用 于破碎防沙林中更新种植替换下来的黄柳、 沙棘的枝丫、 树根等有机废弃生物质原料， 基 本上满足了生物电厂对破碎物料的出料粒度要求。 但是其作业过程中存在容易产生闷车的 问题。 为克服上述双齿辊破碎机作业过程中容易产生的闷车难题， 又设计出公开号为 CN101804372A 的 "组合功能齿辊式破碎机"专用破碎设备。 该机公开了在齿辊转子的下 侧及圆周设有插入到转子轴套边缘的由导料板、 切割筛板、 导向切割立板组成的导料、 破 碎、 筛分及排料装置， 其中导料板和上导料板分别利用单板固定在破碎机的内壁上， 导向 切割立板和切割筛板均设置在导料板上， 利用设置在高速齿辊转子上的多组转动飞刀和储 能飞轮， 解决了前述齿辊破碎过程中易闷车的难题； 但是， 在实际应用中发现其设置在导 料板上的导向切割立板和切割筛板的结构设计仍有不尽人意之处： 如原固定在导料板上的 切割筛板通长设置， 在使用过程中固定在切割筛板中部的导向切割立板处， 极易使切割筛 板堵料， 还存在导向切割立板磨损后不易更换、 切割筛板堵料后不易清理的缺陷， 影响破 碎物料的出料效率； 原导料板和上导料板由单板支撑， 单板强度低， 支撑不稳定， 易使切 割筛板及导向切割立板发生抖动或变形， 降低其使用寿命， 严重时会损坏设备， 因此， 现 有齿辊式破碎机的切割筛板及导向切割立板的结构亟待改进。
【发明内容】
本发明的目的是提供一种适用于双齿辊式破碎机的砧板式梳状剪刃碎料装置， 它从根 本上解决了现有齿辊破碎机的切割筛板等存在的易堵料、 支撑不稳定等缺陷， 与同类产品 相比， 其设计更加合理， 结构匹配科学， 大大提高了支承强度， 便于制造、 安装和维护， 进一步延长设备的使用寿命， 显著提高破碎作业效率， 拓宽适用范围， 完全满足各种齿辊 破碎机对破碎物料出料粒度的要求。
本发明所采用的技术方案是： 该砧板式梳状剪刃碎料装置包括固定在第一齿辊转子下 方的支承座、利用紧固件组装在支承座上的筋板组件和位于第二齿辊转子下方的导料弧板， 其技术要点是： 筋板组件上表面固定有梳齿刃砧板， 支承座的顶部为弧形导料面， 梳齿刃 砧板的表面与支承座的弧形导料面的切面位于同一平面， 梳齿刃砧板前部相邻两梳齿之间 形成的豁口位于筋板组件的两相邻筋板之间，各豁口分别与第二齿辊转子上的刀齿相对应， 并使第二齿辊转子的刀齿顺利通过梳齿刃砧板的豁口； 在梳齿刃砧板表面正对着筋板组件 的筋板正上方固定有均匀排列的剪刃梳齿， 相邻两剪刃梳齿之间形成的豁口分别与第一齿 辊转子的刀齿相对应， 并使第一齿辊转子的刀齿顺利通过剪刃梳齿的豁口； 导料弧板插接 在筋板组件之间， 导料弧板顶部的弧形表面与梳齿刃砧板的豁口底部的表面对齐， 导料弧 板底部利用分别固定在筋板组件前端的剪刃端齿支撑， 并使第二齿辊转子的刀齿顶部顺利 通过导料弧板的弧形表面和相邻两剪刃端齿之间形成的豁口； 前述顶部为弧形导料面的支 承座、 组装在支承座上的筋板组件、 梳齿刃砧板和导料弧板均采用拼装组合式结构。
所述筋板组件由分段组装式连接板和与连接板垂直固定的相互平行排列均匀的筋板构 成。
所述梳齿刃砧板豁口的边缘均设置带耐磨合金层的砧板刃口。
所述剪刃梳齿的边缘均设置带耐磨合金层的梳齿刃口。
所述剪刃端齿的边缘均设置带耐磨合金层的端齿刃口。
本发明具有的优点及积极效果是： 由于本发明的砧板式梳状剪刃碎料装置取消了现有 齿辊破碎机的由单板支撑的固定在导料板上的通长设置的原切割筛板， 采用带弧形导料面 的支承座替代原单板支承， 以全新设计的均匀排列固定在梳齿刃砧板上的剪刃梳齿替换原 切割筛板上的导向切割立板， 所以与同类齿辊破碎机相比， 其设计更加合理， 结构匹配更 科学。 特别是梳齿刃砧板的豁口与相邻两剪刃梳齿之间形成的各豁口交叉设置， 使第一齿 辊转子的刀齿通过相邻两剪刃梳齿之间形成的豁口时， 可以对物料进行再次剪切， 与此同 时， 第二齿辊转子的刀齿通过梳齿刃砧板的豁口时， 不仅可以像刀对砧板上的物料那样进 行切割， 而且还会带走刚被切割暂存留在剪刃梳齿刃口前面的物料， 起到清理作用， 故不 会堵料， 可使物料能够被一次破碎成合格的粒度， 柔性物料再也不会从破碎齿间的空隙漏 出， 显著提高破碎作业效率。 因该装置的顶部为弧形导料面的支承座、 组装在支承座上的 筋板组件、 梳齿刃砧板和导料弧板等件均采用拼装组合式结构， 故其易于制造、 安装和维 护， 显著延长设备的使用寿命。 本发明具有上述结构特点， 可以将多种物料 （如秸秆、 棉 秆、 果木枝条、 树根树皮、 苷蔗叶、 矿石、 煤、 混凝土等） 破碎成合格的出料粒度； 适当 加大两齿辊的中心距， 增加对大块物料的包容角， 能够使大块物料 （煤、 矿石等） 顺利落 入破碎区进行破碎， 可以解决大块物料不易下落的难题。 因此， 本发明不仅从根本上解决 了现有齿辊破碎机的切割筛板等存在的易堵料、 支撑不稳定等的缺陷， 而且采用该结构的 齿辊破碎机还可以拓宽其适用范围， 完全能够满足各种齿辊破碎机对破碎物料出料粒度的 要求。
如果在梳齿刃砧板豁口的边缘或在剪刃梳齿的边缘或在剪刃端齿的边缘均设置带耐磨 合金层的砧板刃口， 那么齿辊转子的刀齿通过时， 更有利于对未被破碎的物料再次进行破 碎， 从而在提高出料粒度合格率的同时， 还可以进一步延长设备的使用寿命。
由于我国农作物耕种面积及固林防沙面积较大，每年有固沙防护林中淘汰下来的灌木、 小乔木数十立方米， 而且农副产品的资源也十分丰富， 所以如果采用本发明人设计的 "枝 丫材专用破碎机"、 "四功能双齿辊破碎机"和 "组合功能齿辊式破碎机"等专用破碎设备， 再配置上本发明的砧板式梳状剪刃碎料装置， 那么就可将长达 3000mm的秸秆及果木枝条 等物料破碎成 80mm以下的符合要求的出料粒度， 供电厂发电用。 经实际检测表明， 以中 小型火力发电厂为例， 仅此一项每年就可以节约原煤 300-400万吨； 适当加大两齿辊的中 心距， 将其用于大块物料 （煤、 矿石等） 的破碎， 这对国内、 外现有矿山企业来讲， 还能 够节约大量成本， 提高破碎效率。
【附图说明】
以下结合附图对本发明作进一步描述。
图 1是本发明的一种结构示意图；
图 2是图 1的侧视图；
图 3是图 1的俯视图；
图 4是图 1中的梳齿刃砧板的一种结构示意图。
图中序号说明： 1第一齿辊转子、 2剪刃梳齿、 3支承座、 4连接板、 5筋板组件、 6剪 刃端齿、 7导料弧板、 8梳齿刃砧板、 9第二齿辊转子、 10梳齿刃口、 11砧板刃口。
【具体实施方式】
根据图 1〜4详细说明本发明的具体结构。该砧板式梳状剪刃碎料装置取消了现有齿辊 破碎机的由单板支撑的固定在导料板上的通长设置的带导向切割立板的原切割筛板， 它包 括固定在第一齿辊转子 1 下方的替代原支撑单板的支承座 3、 利用紧固件组装在支撑稳定 的支承座 3上的筋板组件 5、 固定在筋板组件 5上表面的梳齿刃砧板 8和以全新设计均匀 排列固定在梳齿刃砧板 8上的替换原导向切割立板的剪刃梳齿 2、 位于第二齿辊转子 9下 方的导料弧板 7和剪刃端齿 6等件。 其中顶部为弧形导料面的支承座 3、 组装在支承座 3 上的筋板组件 5、 梳齿刃砧板 8和导料弧板 Ί均应根据实际使用要求和可能， 先按第一齿 辊转子 1和第二齿辊转子 9的规格， 采用分段制造， 然后拼装在一起， 再组合成整体式结 构， 这样既便于整机的制造、 安装和维护， 又延长了设备的使用寿命。
利用紧固件组装在支承座 3上的筋板组件 5由分段组装式连接板 4和与连接板 4垂直 固定的相互平行排列均匀的多个筋板构成。 筋板组件 5每个相互平行的筋板前端都固定有 剪刃端齿 6， 筋板和剪刃端齿 6按一定间距排布， 间距由物料的种类决定。 筋板组件 5的 上表面固定有梳齿刃砧板 8， 梳齿刃砧板 8的表面与支承座 3的弧形导料面的切面位于同 一平面，梳齿刃砧板 8前部相邻两梳齿之间形成的豁口位于筋板组件 5的两相邻筋板之间， 豁口按一定间距排布， 间距由物料的种类决定。 各豁口分别与第二齿辊转子上的各列刀齿 相对应， 并使第二齿辊转子的刀齿顺利通过各自对应的梳齿刃砧板的豁口。 梳齿刃砧板 8 各豁口的边缘均设置带耐磨合金层的砧板刃口 11， 以提高梳齿刃砧板 8对物料的切割质量 和使用寿命。 当上部破碎区的物料未被完全破碎时， 第二齿辊转子 9的刀齿从梳齿刃砧板 8的豁口的间隙 （间隙可根据不同的物料确定） 处通过， 对物料进行二次切割。
在梳齿刃砧板 8表面正对着筋板组件 5的筋板正上方固定有均匀排列相互平行的剪刃 梳齿 2， 剪刃梳齿 2按一定间距排布， 间距由物料的种类决定。 相邻两剪刃梳齿 2之间形 成的豁口分别与第一齿辊转子 1的刀齿相对应， 并使第一齿辊转子 1的刀齿顺利通过剪刃 梳齿 2的豁口。 各剪刃梳齿 2的边缘设置带耐磨合金层的梳齿刃口 10， 以提高梳齿刃砧板 8 对物料的切割质量和使用寿命。 当上部破碎区的物料未被完全破碎时， 第一齿辊转子 1 的刀齿从剪刃梳齿 2之间形成的豁口的间隙 （间隙可根据不同的物料确定） 处通过， 对物 料进行二次切割。 由于梳齿刃砧板 8的豁口与相邻两剪刃梳齿 2之间形成的各豁口交叉设 置， 所以使第一齿辊转子 1的刀齿通过相邻两剪刃梳齿 2之间形成的豁口时， 可以对物料 进行再次剪切； 与此同时， 第二齿辊转子 9的刀齿通过梳齿刃砧板 8的豁口时， 不仅像刀 对砧板上的物料那样进行切割， 而且还会起清理作用， 带走刚被切割暂存留在剪刃梳齿刃 口前面的物料， 故不会发生现有齿辊破碎机的导向切割立板等存在的易堵料等问题。
位于第二齿辊转子 9下方的导料弧板 7插接在筋板 5之间， 并使导料弧板 7顶部的弧 形表面与梳齿刃砧板 8的豁口底部的表面对齐。 导料弧板 7底部利用分别固定在筋板组件 5相互平行的筋板前端的剪刃端齿 6支撑， 相邻两剪刃端齿 6之间形成的豁口分别与第二 齿辊转子 9的刀齿相对应， 并使第二齿辊转子 9的刀齿顶部顺利通过导料弧板 Ί的弧形表 面和相邻两剪刃端齿 6之间形成的豁口， 以便于导出被破碎的物料。 为了对二次未被破碎 的物料再次进行破碎， 形成第三次破碎， 可以在剪刃端齿 6的端齿边缘设置带耐磨合金层 的端齿刃口 （图中未示出）。
对于设置在前述梳齿刃砧板豁口边缘的砧板刃口、 剪刃梳齿边缘的梳齿刃口和剪刃端齿边 缘的端齿刃口来说， 因其采用的均是耐磨合金层， 故这些刃口可以根据需要随时进行修补， 从而确保对物料的切割质量。

1、 一种适用于双齿辊式破碎机的砧板式梳状剪刃碎料装置， 固定在第一齿辊转子下 方的支承座、 利用紧固件组装在支承座上的筋板组件和位于第二齿辊转子下方的导料弧 板， 其特征在于： 筋板组件上表面固定有梳齿刃砧板， 支承座的顶部为弧形导料面， 梳齿 刃砧板的表面与支承座的弧形导料面的切面位于同一平面，梳齿刃砧板前部相邻两梳齿之 间形成的豁口位于筋板组件的两相邻筋板之间，各豁口分别与第二齿辊转子上的刀齿相对 应，并使第二齿辊转子的刀齿顺利通过梳齿刃砧板的豁口；在梳齿刃砧板表面正对着筋板 组件的筋板正上方固定有均匀排列的剪刃梳齿，相邻两剪刃梳齿之间形成的豁口分别与第 一齿辊转子的刀齿相对应，并使第一齿辊转子的刀齿顺利通过剪刃梳齿的豁口； 导料弧板 插接在筋板组件之间，导料弧板顶部的弧形表面与梳齿刃砧板的豁口底部的表面对齐，导 料弧板底部利用分别固定在筋板组件前端的剪刃端齿支撑，并使第二齿辊转子的刀齿顶部 顺利通过导料弧板的弧形表面和相邻两剪刃端齿之间形成的豁口；前述顶部为弧形导料面 的支承座、 组装在支承座上的筋板组件、 梳齿刃砧板和导料弧板均采用拼装组合式结构。
2、 根据权利要求 1所述的砧板式梳状剪刃碎料装置， 其特征在于： 所述筋板组件由 分段组装式连接板和与连接板垂直固定的相互平行排列均匀的筋板构成。
3、 根据权利要求 1所述的砧板式梳状剪刃碎料装置， 其特征在于： 所述梳齿刃砧板 豁口的边缘均设置带耐磨合金层的砧板刃口。
4、 根据权利要求 1所述的砧板式梳状剪刃碎料装置， 其特征在于： 所述剪刃梳齿的 边缘均设置带耐磨合金层的梳齿刃口。
5、 根据权利要求 1所述的砧板式梳状剪刃碎料装置， 其特征在于： 所述剪刃端齿的 边缘均设置带耐磨合金层的端齿刃口。
