Description

低进位全周角反击式破碎机
技术领域
本发明属于破碎机技术领域， 更具体的说是一种低进位全周角反击式破碎 机。
背景技术
反击式破碎机 （简称反击破） 是一种新型高效率的碎矿设备， 其特点是： 体积小， 构造简单； 破碎比大 （可达 40)， 生产能力大； 产品粒度均匀， 呈正 方形且削去棱角， 即具有对产品颗粒的整形功能。 随着我国建筑业的发展， 整 形石料需求量在逐年增长， 因此反击式破碎机的需求量也在逐年增长。
反击式破碎机利用高速旋转的转子对投进破碎腔内的物料产生高速冲击， 把物料抛射到反击板上， 物料受重力和反弹力落下来， 但高速旋转的转子带动 板锤沿切线方向再次撞击物料，把物料抛向另一块反击板，物料被进一步破碎， 然后又从反击板反弹到板锤， 上述过程不断地重复， 在该过程中由于物料受到 板锤的打击、 反击板的冲击以及物料相互之间的碰撞， 物料不断产生裂缝， 直 至松散粉碎。 当物料粒度小于反击板与板锤之间的排料缝隙时， 就被卸出破碎 腔。 反击破的优越性在于它利用高速打击和多次重复反击的破碎原理， 使破碎 后的物料更呈准正方体，且削去棱角，在建筑行业用于水泥砼的高品味的石料， 大多是选用反击式破碎机作最后一道破碎来完成的成品料， 这一功能也称为整 形功能。 而整形功能的效果与反击效率直接相关。
现有技术反击式破碎机如图 1所示，包括机架 1，机架 1上设有进料通道 2、 反击板 5、 角度调节装置 7、 转子总成和排料通道 8。 反击式破碎机的进料通道 口均设置在转子轴线上方。 进料后先与转子上侧部位相接触， 而这种结构在如 中国专利文件中也有公开，如中国专利号为 CN03282600. 1和 CN200520047549. 2 的两种反击式破碎机所示的结构都如此）。
这种结构的先天不足在于：
①原料从反击破上方进料通道进入， 首先与转子正上方开始接触， 然后作 打击 -反击 -打击 -反击……破碎，在高速运转的转子带动下匆匆而过，物料在破 碎腔中滞留时间短， 而反击次数少， 且不能控制滞留时间， 而整形功能的发挥 是与打击、 反击的次数相关的。
②从转子中心线以下到逆向一侧的 90 ° 范围内 （占整个转子 1/4周长）， 是破碎的盲区， 该区域是不产生破碎作功的， 这是结构性浪费， 是现有技术反 击破的严重缺陷。
③进料通道口设置在转子上方， 占用了反击板的覆盖空间和反击区间， 即 浪费了宝贵的结构资源。 原料从进料通道口投入到排出， 仅在大约 180 ° 的区 间里产生反击破碎工作， 设备的结构利用率很低。 发明的公开
本发明的目的在于提升现有技术反击式破碎机的整形功能与效率， 提供了 一种延长物料在破碎腔内的滞留时间、 增加物料撞击次数、 大幅提高整形效果 的反击式破碎机。
为了达到以上目的， 本发明是通过以下技术方案来实现的： 一种低进位全 周角反击式破碎机， 包括机架， 机架上设有进料通道、 反击板、 角度调节装置、 转子总成和排料通道； 转子总成的周向上设置有板锤， 转子总成与反击板之间 形成破碎腔， 反击板一端直接铰接在机架上， 另一端通过角度调节装置设于机 架上； 其特征在于， 所述进料通道设置于机架的一侧， 进料通道的下端位于转 子总成的水平中心线以下位置。 作为优选， 在进料通道的上端与邻近进料通道 的反击板之间增设一控制板， 控制板一端直接铰接在机架上， 另一端通过角度 调节装置设于机架上。
本发明的技术特征在于：
①低进位。 现有技术下反击式破碎机是物料先与转子的水平中心线以上部 位接触， 然后进入 "撞击与反击" 的破碎作功过程， 本发明改进为先与转子水 平中心线以下部位接触， 即先将物料从下往上抛起， 再进入 "撞击与反击" 的 破碎作功过程的。
②全周角。 由于本发明将物料先与转子水平中心线以下部位接触破碎， 消 除了现有技术的破碎盲区， 使本发明实现了转子全周角全程参与反击破碎， 提 高了设备原结构的利用率。
③可控制。本发明增设了一块控制板（控制板同时也是反击板)， 而设置控 制板的位置恰恰是现有技术中原来的进料通道位置， 也是原先物料开始破碎的 起点。 从本质上看， 本发明将物料的破碎起点是提前了 90 ° 区域， 物料从转子 水平中心线以下就开始撞击， 把物料从下往上抛起到控制板后反击， 这一过程 是本发明中新增加的一段破碎过程， 从控制板以后的反击破碎是与现有技术反 击式破碎机是相同的。
控制板所处的是一个重要位置。 在这位置上通过调整控制板的角度， 可控 制物料往前推进或往后滞留。 ①反击板角度向前倾、 则物料迅速向前反击， ② 反击板角度向后、 则物料往后反击。 从理论上分析， 在极端情况下， 可控制物 料基本上不往前走（实用中这是有害的、会产生堵料焖机现象）， 这一特性说明 只要适当控制投放物料的数量， 即可控制物料在半滞留状态下在腔内充分地反 击， 直至获得整形效果理想的物料颗粒。
让物料在破碎腔内延长 （并控制） 滞留时间， 从而增加反击次数， 以达到 对物料的高效整形目的， 是本发明的核心技术。
作为优选， 所述的反击板为弧形， 在反击板上设置成网状网孔结构。 反击 板的形状可以根据需要制造为多种方式， 其中一种可以是由多个弧形反击板位 于机架的一侧， 与转子总成形成破碎腔， 多个反击板又大致能排列形成一个弧 形； 还有一种， 可以是由一块弧形反击板构成， 由进料通道一直到出料通道， 反击板也是位于机架的一侧， 与转子总成形成破碎腔。
反击板设置为网状网孔结构， 可带来如下好处：
( 1 )带有网状网孔结构的反击板使得物料在破碎腔中反弹无序，形成一种 散射现象， 使得物料的每个棱角都被相互击打打磨， 对成品料的针、 片状问题 能够得到很好地解决， 这样获得的规格料品质很高。
( 2 )网状网孔结构使得物料形成散射现象后，还能使物料与物料之间相互 碰触， 进一步细碎的同时， 又能减少机器损耗， 降低成本。
( 3 )反击板制造过程中， 要进行淬火热处理工序， 即把加温至炽热的破碎 壁浸入水中快速冷却， 以达到淬火硬化的目的。 本实用新型将反击板设置了密 密麻麻的网状孔群， 大大增加了淬火反击板与水的接触面积， 极大有利于淬火 工艺中的淬透性， 从而提高了反击板的硬度、 耐磨性和使用寿命。
作为优选， 进料通道的下侧面上设置有导料板， 导料板下端与转子总成斜 下方位置相适应。 导料板在这里起到两个方面的作用： 一是精准导料至转子中 心线以下的位置与转子上的板锤相接触， 实现上述功能； 二是起到反击板的作 用， 被控制板控制反弹回来的物料， 在导料板上再次进行反弹， 反弹力小于重 力后，顺着导料板再次被引导到转子中心线以下的位置，开始新一轮整形破碎。 同时而且其上面的物料会累积， 这一现象有利于减少金属磨耗， 降低成本。
作为优选， 导料板和控制板也为弧形， 在导料板和控制板上也均设置成网 状网孔结构。 导料板和控制板呈网状结构带来的有益效果是： 经网状结构反击 板反射的物流呈 "无序散射状"，它相对于现有技术实心平板结构反击板反射的 "有序折射状" 物流来说， 物料与物料之间相互碰撞的概率更高， 破碎与整形 更充分、 更高效。
作为优选， 该网状结构为由六边形网孔形成的蜂窝状。 蜂窝状是网状结构 中最特殊的结构，它不仅具有网状结构的所有特性，而且其更容易实现随机的、 不定向的剪切破碎力， 使其具有更大的破碎咬合力。 此外， 所有网状结构中， 在形成相同大小面积的情况下， 蜂窝状形成的空心比更大 （空心比=空心面积 / 总面积）， 它强化了 "劈碎、折碎、挤碎"等破碎功能， 更有利于提高破碎效率。
通孔为本发明网孔设计的首选实施方式， 其中小于通孔直径的规格尺寸物 料能够提前退出破碎， 使得破碎不会过渡。
作为上述方案的替换方案， 所述网孔为盲孔。 可以实现料打料的效果。 作为优选， 所述排料通道上设置有一均整板。 通过均整板的设置， 能有效 过滤碎石的规格， 提高破碎效果。 均整板可以为弧形或者平板形。
本发明的显著效果是， 通过增加有效的物料反击次数， 提升反击破的整形 功能。 同时， 本发明还带来如下有益效果： ①转子全周角全程参与反击破碎， 提高了设备利用率， 降低了成本。 ②导料板不但起到反击板作用， 而且其上面 的物料会累积， 这一现象有利于减少金属磨耗， 降低成本。 附图说明

在进料通道 2的上侧与邻近进料通道 2的反击板 5之间增设一控制板 6， 控制板 6—端直接铰接在机架 1上，另一端通过角度调节装置 7设于机架 1上。
控制板 6和导料板 9也为弧形板。
破碎过程： 采用进料通道低位设置， 使得投入破碎腔里的物料在转子中心 线以下的位置与转子上的板锤相接触，然后被高速旋转的板锤抛射到控制板上， 撞击到控制板， 物料受到控制板的反作用力， 便立即沿反作用力方向返弹。 调 节新增加的控制板的角度， 可调控物料前进的速度： ①反击板角度向前倾、 则 物料迅速向前反击， ②反击板角度向后、 则物料往后反击。 从理论上分析， 在 极端情况下， 可控制物料基本上不往前走 （实用中这是有害的， 会产生堵料焖 机现象）， 只要适当控制投放物料的数量， 即可控制物料在半滞留状态下在腔内 充分地反击， 直至获得整形效果理想的物料颗粒。
