摘要: A mixer seal assembly for a closable vessel having a dynamic mixer shaft seal in a bore in a vessel flange and a static seal for vessel transport formable by insertion of a disconnected lower portion of a fast connect coupling which is fast to install on the mixer shaft into the flange bore above the dynamic seal. The resulting seal assembly can seal the vessel for over-the-road transport. The dynamic seal includes a circular lip which sealingly engages the surface of the mixer shaft. The static seal includes an O-ring disposed in a first annular groove in the coupling portion. A shaft bushing disposed adjacent to the shaft seal in the flange bore minimizes shaft runout in the shaft seal and permits use of relatively rigid and dry running materials such as fluorocarbon polymer in the shaft seal. In the shut-off position with the coupling portion inserted into the vessel flange, a spring pin mounted in the vessel flange can engage a second annular groove in the coupling portion to lock the coupling portion in the flange bore. In an alternative embodiment for use in retro-fitting existing vessels, the vessel flange of the invention may be configured to sealingly conform to an existing vessel flange.
摘要翻译: 一种用于可关闭容器的混合器密封组件,其具有在容器法兰中的孔中的动态混合器轴密封件和用于容器输送的静态密封件,其可通过插入快速连接联接器的断开的下部而快速地安装在混合器轴上 进入动态密封件上方的法兰孔。 所得的密封组件可以密封容器用于越野运输。 动态密封件包括密封地接合混合器轴的表面的圆形唇缘。 静态密封件包括设置在联接部分中的第一环形槽中的O形环。 在轴密封件中与轴密封件相邻设置的轴套使轴密封件中的轴跳动最小化,并且允许在轴封中使用相对刚性和干燥的运行材料,例如氟碳聚合物。 在连接部分插入容器凸缘的关闭位置,安装在容器凸缘中的弹簧销可以接合联接部分中的第二环形槽,以将联接部分锁定在凸缘孔中。 在用于改装现有容器的替代实施例中,本发明的容器凸缘可构造成密封地符合现有的容器凸缘。
