Description

一种圆筒形煤气柜侧板刮油装置 技术领域 本发明涉及一种圆筒形煤气柜， 特别涉及一种圆筒形煤气柜的侧 板刮油装置。 背景技术 圆筒形柜是一种具有圆筒形外形特征的干式煤气柜，其活塞采用 稀油和条形橡胶制品密封装置密封， 近十年来国内已建设五十余座， 总投资额超过二十亿元。 目前， 圆筒形柜的活塞速度可达 3m/min， 但与活塞速度高达 7m/min的橡胶膜密封煤气柜相比， 圆筒形柜活塞 运行速度仍然偏低， 因此， 如何提高圆筒形柜活塞运行速度一直是业 界研究的前沿问题。
圆筒形柜是稀油密封型煤气柜的一种， 其密封装置由密封橡胶 条、 橡胶夹持机构、 悬吊机构、 杠杆重锤机构和兜底帆布等组成， 密 封装置通过悬吊机构实现竖向定位， 吊挂在固定于活塞上的吊梁上， 通过成百上千组杠杆重锤机构水平加力，使密封橡胶条能够时刻跟踪 侧板变形。通过活塞油沟内一定液位高度密封油的液压与活塞密封装 置实现密封面处有效密封， 防止气体泄漏。
活塞油沟内的密封油从柜体侧板与圆筒形柜的密封橡胶之间的 微小间隙漏下， 沿侧板内壁落入煤气柜底部油沟中， 再经油连通管进 入油泵站内。 密封油在油泵站内首先经过油水分离器进行油水分离， 分离出的密封油经油泵泵送至柜体上部的预备油箱内，预备油箱内溢 流的密封油通过溢流口进入煤气柜内部， 沿侧板内壁流下， 补充到活 塞油沟内， 以保证活塞油沟内密封油液位不低于设计值。
从上述密封油循环可见，密封油从活塞油沟至底部油沟以及从预 备油箱至活塞油沟均是沿侧板内壁流下，因密封油均有一定的粘度且 由于密封效果的考虑粘度数值不宜过小，因此侧板上附着一层密封油 膜。 尤其在气温较低时， 因油品粘度增大， 附着量也相应增加。 此种 附着量， 可定义为正常附着量， 在煤气柜设计过程中已计入密封油总 量。 活塞油沟密封油高度过低， 容易造成煤气泄漏； 活塞油沟密封油 高度太高，则密封装置受到的水平液压力加大且各层密封橡胶受力不 平衡， 密封装置容易倾翻且密封橡胶寿命縮短。
煤气柜活塞快速下降时， 密封油沟同活塞下降速度一致， 当气温 较低时， 活塞油沟中接触侧板内壁的密封油粘度大， 其下降速度小于 活塞速度， 即脱离活塞油沟附着在侧板上。 据统计附着厚度大约
2. 0匪， 按煤气柜活塞以 5m/min下降速度运行 lOmin, 即活塞下降行 程 50m计， 则活塞油沟油位高度降低约 166mm (活塞油沟宽度按 0. 6m 计）。 而下降行程范围内侧板上的正常附着密封油随密封橡胶下缘下 降， 但此油量在活塞下降时期内无法完成密封油循环， 也无法补充到 活塞油沟内。此种工况下， 势必造成活塞油沟油位偏低无法保证有效 密封而造成煤气泄漏。如果简单加高活塞油沟密封油高度，如前所述， 密封装置容易倾翻且密封橡胶寿命縮短。
专利号 201120266102. X 《一种稀油密封气柜用侧板刮油装置》 公开了一种解决该问题的刮油装置。 该刮油装置布置在宽 0. 6m的活 塞油沟上方， 采用弹簧拉紧保证刮油橡胶贴紧侧板。 由于活塞钢结构 上的活塞密封装置相邻杠杆重锤机构间人员进出的孔洞大小为〜 600mm (长） X〜370mm (宽）， 该专利的弹簧和支撑杆的根部又必须 避开杠杆重锤机构而占用人员进出的孔洞面积，导致人员进入活塞油 沟的通道狭窄； 如果加大此处孔洞长度， 则活塞密封装置的加力压紧 体系甚至密封橡胶的刚度都要重新设计， 改动量大且密封效果下降。 并且， 刮油橡胶始终贴在侧板上， 刮油橡胶工作时间长， 寿命短。
因此，需要一种可解决因密封油附着在煤气柜侧板上导致活塞油 沟油位下降的装置，并且该装置还不能影响工人人员进入煤气柜检修 密封装置的通道。 发明内容 有鉴于此， 本发明的目的是提供一种圆筒形煤气柜侧板刮油装置， 其能在活塞下行时将附着在煤气柜侧板上的密封油刮下， 从而使密封 油流到活塞油沟中， 保证活塞油沟中的油位高度， 保证密封效果， 并 且本装置不会干涉工作人员进入密封装置的检修通道。 本装置的具体 方案如下：
本发明圆筒形煤气柜侧板刮油装置， 包括刮油件和支撑杆， 所述 支撑杆一端与刮油件连接、 另一端与固定在煤气柜活塞上的吊梁铰 接， 所述支撑杆可绕铰接轴向煤气柜侧板转动并在重力作用下使刮 油件压靠在煤气柜侧板上， 所述支撑杆还可绕铰接轴向煤气柜活塞 侧转动使刮油件脱离煤气柜侧板。

在温度低时， 密封油粘度较大， 活塞下移会有较多的密封油附着 在侧板上。 在这种情况向， 推动支撑杆 2转动将刮油件 1压在煤气柜 侧板 5上， 刮油件 1可将侧板上附着的密封油刮下使其流回活塞油沟， 这样可保证活塞油沟中油位高度， 保证密封效果。
在温度高时， 密封油粘度小， 密封油粘附在煤气柜侧板 5上的量 非常小， 密封油可顺利流回活塞油沟。 在这种情况下， 工作人员可推 动支撑杆 2绕铰接轴转动使刮油件 1脱离侧板倒向活塞侧， 刮油装置 不工作， 可延长刮油装置寿命.
本刮油装置位于煤气柜侧板 5和吊梁 4之间，其不会对位于吊梁 4 和煤气柜活塞 3之间的检修通道造成干涉使检修通道变窄， 工作人员 可顺利进入检修通道对密封装置进行维修。
