请参阅图 3将密封圏放入所述烘干装置工作台上设置的密封圏卡槽后 的侧面结构剖视图和图 4离子膜与所述密封圏在所述烘干装置工作台成型 后的侧面结构剖视图。 在图 3中， 所述密封圏 102已经装入工作台 106的 卡槽内， 所述密封圏 102下底面为平面， 卡装在所述工作台 106的密封圏 卡槽 108内， 所述密封圏 102的上底面 104上设置的凸点凸出于所述密封 圏卡槽 108, 所述密封圏 102的上底面 104凸点的高度等于或略小于所述 侧壁 107的高度。
利用本发明一种密封圏离子膜一体化组件的生产方法生产密封圏离子 膜一体化组件时， 只需要事先将密封圏 102卡装在所述工作台 106的密封 圏卡槽 108内，再将所述步骤 C中经过沉淀处理的制造离子膜的溶液倒入 工作台 106内， 因所述工作台 106周边设置有侧壁 107, 所以， 在所述工 作台 106内将存留定量的离子膜溶液， 此时， 通过所述钒液流电池密封圏 离子膜一体化组件生产装置上设置的加热装置 109进行加热， 使所述离子 膜溶液凝固成固态， 这时所述密封圏与所述离子膜 101即成为一体式的结 构了， 具体结构示意图可以参阅图 4离子膜与所述密封圏在所述烘干装置 工作台成型后的侧面结构剖视图。
根据本发明所公开的技术方案所生产的密封圏离子膜一体化组件中的 离子膜表面非常平整， 而且离子膜的韧性和气密性非常好， 离子膜的使用 寿命大大增加， 直接将离子膜与密封圏设计成一体式结构安装在第一框板 和第二框板上， 并一体化连接固定住， 安装后的密封圏离子膜一体化组件 中的离子膜绝对平整， 不易发生错位， 不褶皱， 而且密封圏离子膜一体化 组件在使用过程中的密封效果更好， 避免了漏液和正负液串液现象， 使钒 电池性能更稳定也提高了钒液流电堆的工作效率。
以上内容是结合具体的优选技术方案对本发明所作的进一步详细说 明， 不能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术 领域的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若 干筒单推演或替换， 都应当视为属于本发明的保护范围。
