Description

一种红土镍矿烘干破碎机的转子系统 技术领域
本发明涉及一种破碎机技术领域，特别是涉及一种红土镍矿烘干破碎机的转子系统。
背景技术
红土镍矿在开发利用过程中主要使用火法工艺和湿法工艺，两种工艺的共同点都是将红土镍矿破碎，但是红土镍矿含水率较高，原矿脱水困难，只有将其破碎之后再烘干，才能更好的为下一步工艺处理。
红土镍矿通常含水率在30％左右，目前能处理高含水率的破碎机少之又少，普通的破碎为控制出料粒度大多都使用有筛网蓖底，遇到高含水率的物料很容易堵塞，导致破碎机的各种故障发生。
红土镍矿破碎机工作原理是，以单台电动机为动力，通过电动机皮带轮，由三角皮带和槽轮驱动大轴，安装在转子上的锤头飞速旋转，将进入由固定衬板、活动锤头和边衬板组成的破碎腔内的物料破碎，并通过与上部进料口相同方位的下部排料口将成品物料排出，从而增加了物料的破碎行程，使物料更加细，产量更加高。
但是现有的红土镍矿破碎机在进行破碎时，由于机体较为笨重，锤头不能得以很好很灵活的转动，导致破碎出来的颗粒均匀度差，并且效率较低，不利于生产。
发明内容
为了克服上述现有技术的不足，本发明提供了一种红土镍矿烘干破碎机的转子系统，其目的在于合理地布局和规划红土镍矿烘干破碎机的转子系统，进而保证转子系统能够以较小的占用空间和较轻的重量，实现与现有的破碎机的转子相同的功能，并且提高其工作效率，较少其发热量，同时由于锤头结构布置合理，保证了破碎机加工得到的物料均匀度好。
本发明所采用的技术方案是：一种红土镍矿烘干破碎机的转子系统，包括连接在主轴上的分段错位布置的锤头结构，分段错位布置的锤头结构两端的主轴上还设有分别一个散热盘和轴承座、端锤盘，分段错位布置的锤头结构的两端分别 通过一个双向定位结构固定主轴和其对应的端锤盘；其中分段错位布置的锤头结构至少包括短分布式锤头组件和长分布式锤头组件；此外，短分布式锤头组件包括至少两个短锤盘和若干个短盘杆，每一个短锤盘套在主轴上，每一个短锤盘的周向上依次连接有若干排第一段短锤头和若干排第二段短锤头，若干排第一段短锤头和若干排第二段短锤头分别通过若干个短盘杆连接固定在端锤盘上，并且相邻的两排的第一段短锤头和第二段短锤头分别交错布置；长分布式锤头组件包括至少两个长锤盘和若干个长盘杆，每一个长锤盘套在主轴上，每一个长锤盘的周向上依次连接有若干排第一段长锤头和若干排第二段长锤头，若干排第一段长锤头和若干排第二段长锤头分别通过若干个长盘杆连接固定在端锤盘上，并且相邻的两排的第一段长锤头和第二段长锤头分别交错布置。
进一步地，每一个短锤盘上连接的若干排第一段短锤头和第二段短锤头均通过一个隔环隔离；两个相邻的隔环安装的角度不一致，进而保证相邻的两排第一段短锤头和第二段短锤头分别交错布置；同样地，每一个长锤盘上连接的若干排第一段长锤头和若干排第二段长锤头均通过一个隔环隔离，两个相邻的隔环安装的角度不一致，进而保证相邻的两排第一段长锤头和若干排第二段长锤头分别交错布置。
进一步地，每一个隔环包括本体和若干个隔断臂，其中若干个隔断臂沿本体的周向间隔地布置，每两个相邻的隔断臂之间设有锤头通道，第一段短锤头和第二段短锤头、第一段长锤头、第二段长锤头分别置于其对应的锤头通道内。
进一步地，第一段短锤头和第二段短锤头、第一段长锤头、第二段长锤头沿其自身的对应的周向上均布分别有六至八排。
进一步地，每一个双向定位结构包括一个卡板和一个衬套，其中每一个卡板嵌入其对应的端锤盘内，每一个衬套套在其对应的主轴上；并且每一个卡板和衬套分别通过一个固定螺栓固定连接端锤盘和主轴。该结构的设置，防止了卡板脱落,从而对锤轴在周向上和轴向上都进行了限位，并且双向定位结构简单、更加可靠、装卸方便。
进一步地，每一个端锤盘包括盘座和盘体，其中盘座采用铸造制成，盘体、长盘杆和短盘杆均采用锻造制成；盘座和盘体焊接而成端锤盘。
进一步地，盘体、长盘杆和短盘杆的表面上还设有堆焊耐磨层，这种结构在保证了高温环境下的转子结构的韧性和强度同时,减少了设备重量,还大大降低了转子的加工难度和加工成本。
进一步地，主轴上还设有风冷循环装置和稀油冷却循环装置。
进一步地，风冷循环装置设于破碎机壳体与主轴之间，稀油冷却循环装置设于轴承座内。采用风冷和稀油循环冷却双重冷却方式,更好地解决高温工作环境下大量的热量通过主轴内部传递到轴承的冷却和润滑问题。在破碎腔体壳体与轴承座间的区域设计成风冷区,主轴上设置散热盘,通过风机鼓风冷却。主轴承采用强制循环润滑冷却方案,主轴承座内的油既起轴承润滑作用,又吸收了主轴传递过来的热量后回流至稀油站,经冷却和过滤后再次循环。
与现有技术相比，本发明的有益效果是：本发明的转子系统，采用分段错位布置的锤头结构、散热盘和轴承座、端锤盘以及双向定位结构，实现对转子系统的布局和规划，实现了分段错位布置的锤头结构在布局锤头时，沿轴向上每排分成两段,它们相互之间错开,且相邻两排锤头之间在周向上通过隔环的调整在轴向上错开,以提高锤头横扫截面。新型的锤头布置方式,减小了锤轴的长度,减小了锤头、锤头主轴的更换空间,且更换更为方便快捷。

在图1中还可以看出，主轴1上还设有风冷循环装置19和稀油冷却循环装置18。风冷循环装置19设于破碎机壳体与主轴之间，稀油冷却循环装置18设于轴承座12内。采用风冷和稀油循环冷却双重冷却方式,更好地解决高温工作环境下大量的热量通过主轴内部传递到轴承的冷却和润滑问题。在破碎腔体壳体与轴承座间的区域设计成风冷区,主轴上设置散热盘,通过风机鼓风冷却。主轴承采用强制循环润滑冷却方案,主轴承座内的油既起轴承润滑作用,又吸收了主轴传递过来的热量后回流至稀油站,经冷却和过滤后再次循环。
本发明的转子系统，采用分段错位布置的锤头结构11、散热盘3和轴承座12、端锤盘16以及双向定位结构2，实现对转子系统的布局和规划，实现了分段错位布置的锤头结构11在布局锤头时，沿轴向上每排分成两段,它们相互之间错开,且相邻两排锤头之间在周向上通过隔环的调整在轴向上错开,以提高锤头横扫截面。新型的锤头布置方式,减小了锤轴的长度,减小了锤头、锤头主轴的更换空间,且更换更为方便快捷。
本发明的实施例公布的是较佳的实施例，但并不局限于此，本领域的普通技术人员，极易根据上述实施例，领会本发明的精神，并做出不同的引申和变化，但只要不脱离本发明的精神，都在本发明的保护范围内。
