Description
技术领域
本实用新型涉及轮胎生产装置领域，详细地讲是一种密炼机上顶栓活塞杆密封装置。
背景技术
众所周知，在轮胎生产过程中，胶料主要是依靠密闭式炼胶机来混炼实现的。目前在整个轮胎行业中存在密炼车间粉尘污染较重的问题。特别是在混炼过程中因密炼机的上顶栓活塞杆等部位密封不好，造成的碳黑泄漏。碳黑粉尘在车间内四处飘飞，使设备、环境、工人受到碳黑的污染，影响车间的环境清洁，增加了工人卫生保洁的劳动强度，影响了工人身体健康和工作积极性。这里以密炼机上顶栓活塞杆部位为例，在混炼过程中，需要上顶栓以16-18MPa的压力间断地强制胶料在混炼室内搅炼，过程中上顶栓需要上下升降活动，陀头与料仓有1mm间隙，导致活塞杆与导套之间部位很难密封住混炼过程中的碳黑，此处泄漏的炭黑由于润滑不到位，造成活塞杆被磨擦拉伤，从而增加了炭黑的泄漏量。
传统的密炼机活塞杆密封形式使用盘根或V型密封圈组，通过剖分式压套定位来压实密封，下部安装刮环。碳黑属于粉粒料，活塞杆的上下活动，在很短时间里就会将盘根或密封圈、刮环摩擦损耗掉，密封处间隙加大后就会泄漏，就需要人为频繁压实密封圈或盘根，更换刮环，人工频繁添加润滑脂，这种结构存在如下缺陷：一是盘根或密封圈、刮环使用寿命短，更换频次多，增加工人劳动强度；二是增加维修费用；三是密封效果差，密封寿命短。
发明内容
为了克服现有技术的不足，本实用新型提供一种密炼机上顶栓活塞杆密封装置，可杜绝活塞杆粉尘泄露，持续保持密炼车间环境清洁，降低活塞杆磨损，延长活塞杆的使用寿命。
本实用新型解决其技术问题所采用的技术方案是：一种密炼机上顶栓活塞杆密封装置，设有活塞杆，活塞杆上套装有剖分式压套，其特征在于，剖分式压套的内腔壁沿圆周加工有油槽，剖分式压套上沿圆周对称位置加工有两个与油槽相连通的油道，剖分式压套下方的活塞杆上套装有密封圈，法兰套筒紧密套装在活塞杆、密封圈及剖分式压套上，法兰套筒下端的活塞杆上套装有刮环。
本实用新型还可通过如下措施来实现：刮环上套装有刮环压板，刮环压板经刮环压板固定螺栓固定在法兰套筒的下端。活塞杆与法兰套筒、密封圈及刮环的内腔壁紧密滑动配合。
本实用新型的有益效果是，结构简单，可杜绝活塞杆粉尘泄露，持续保持密炼车间环境清洁，降低活塞杆磨损，延长活塞杆的使用寿命。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1为本实用新型的结构示意图。
图中1.刮环，2.刮环压板，3.法兰套筒，4.密封圈，5.剖分式压套，6.料仓上压盖，7.油槽，8.油道，9.法兰套筒固定螺栓，10.压套调整螺栓，11.刮环压板固定螺栓，12.活塞杆。
具体实施方式
如图1所示，设有活塞杆12，活塞杆12上套装有剖分式压套5，剖分式压套5的内腔壁沿圆周加工有油槽7，剖分式压套5上沿圆周对称位置加工有两个与油槽7相连通的油道8，剖分式压套5下方的活塞杆12上套装有密封圈4，法兰套筒3紧密套装在活塞杆12、密封圈4及剖分式压套5上，剖分式压套5经压套调整螺栓10固定在法兰套筒3的上端，法兰套筒3下端的活塞杆12上套装有刮环1，刮环1上套装有刮环压板2，刮环压板2经刮环压板固定螺栓11固定在法兰套筒3的下端，法兰套筒3、密封圈4及刮环1的内腔壁与活塞杆12紧密滑动配合，法兰套筒3经法兰套筒固定螺栓9固定在料仓上压盖6上。本实用新型油道8经油管接到油泵上，根据润滑油的消耗量设定加注频率，润滑油经油道8向油槽7内注润滑油，通过圆周注入的润滑油来降低密封圈4和刮环1的磨损，同时又能填补磨损的微小间隙来封堵碳黑粉尘的泄漏。
