本发明提出一种多膜壳组合单元及多膜壳组合方法， 该多膜壳组合单元是由多支 膜壳并列集束而成， 其中， 每支膜壳的原水口、 浓水口分别与相邻的膜壳的原水口、 浓 水口相连并密封， 使得各膜壳的原水口相互贯通， 浓水口也相互贯通， 该多膜壳组合单 元具有共享的原水口、 浓水口分别与管道相连， 所述多支膜壳的原水口间形成原水贯通 通道， 所述多支膜壳的浓水口间形成浓水贯通通道。 工作时， 每个多膜壳组合单元通过共享的原水口进水， 由于多支膜壳的原水口相 连通， 原水进入每个多膜壳组合单元后分布到每个膜壳中； 在工作压力下， 原水渗透过 膜元件被分离为净水与浓水； 由于多支膜壳的浓水口也相连通， 浓水汇合在一起， 通过 共享的浓水口排出。 由于每个多膜壳组合单元设有较少数量的原水口、 浓水口 （例如可 只设置一个原水口、 一个浓水口） ， 因此， 工程安装时， 只需要完成较少数量的原水口 及浓水口与管道的装配即可， 从而节省了大量卡箍， 降低了工程成本， 减少了密封点， 降低了泄漏隐患， 减少了工程的安装量， 节省了装置的占地面积。
较佳地， 各膜壳单元的原水口、 浓水口是通过接管相连并密封， 该接管仅设置于 相邻二膜壳单元外部的邻接开孔部位， 而未延伸至膜壳内腔中， 从而不会影响膜壳内部 结构以及后续膜单元的装配； 进一步地， 所述接管可以采用外接式结构， 其两端与膜壳 开孔处的外壁相齐， 且该接管与膜壳之间可采用平面密封； 或者， 所述接管还可采用内 接式结构， 该接管的两端插入膜壳开孔内， 接管与膜壳之间可采用轴向密封。
较佳地， 多支膜壳并列集束后， 还可以选择利用捆固件捆扎成一体， 而且， 可根 据需要选择用刚性或柔性捆带， 该捆固件较佳是对应于该原水贯通通道及浓水贯通通道 分别设置； 进一步地， 对应该捆带还可设置压力调节器， 用以调节工作时的压力变化。
较佳地， 本发明的多支膜壳的相贯通的原水口、 浓水口分别位于垂直于轴向的二 平面内， 捆固件较佳至少在对应于所述二平面的位置而设置， 以利达到更好的连接固定 效果。
本发明中， 多支膜壳可采用多种并列集束方式进行组合， 即组合单元的端面可呈 多种形状， 例如可呈直线、 三角形及多边形等分布形式。
为了便于对本发明的准确理解， 下面配合附图及具体实施例对本发明多膜壳组合 单元及组合方法的具体实施方式作进一步的详细说明。
第一实施例
如图 1、 图 2、 图 3所示， 分别为本发明的第一实施例的立体图、 正视图及俯视图， 本实施例中， 该多膜壳组合单元的端面呈直线分布。 其中， 该多膜壳组合单元是由多支 膜壳 1并列集束而成， 其中， 每支膜壳 1的原水口 12、 浓水口 13分别与相邻的膜壳的 原水口 12、浓水口 13通过接管 6相连并密封， 使得各膜壳的原水口 12相互贯通， 浓水 口 13 也相互贯通， 从而使得该多膜壳组合单元具有共享的原水口 2、 共享的浓水口 3 分别与管道 （图中未示出） 相连， 即共享的原水口 2与原水管道相连， 共享的浓水口 3 与浓水管道相连。 本实施例中， 每支膜壳的原水口、 浓水口分别与相邻的一支膜壳的原水口、 浓水 口通过接管 6相连， 接管 6为外接式结构， 其两端与膜壳 1的开孔处的外壁相齐， 不影 响膜壳内部结构； 接管 6与膜壳 1之间采用密封胶圈 7平面密封。 具体地， 膜壳 1的侧 壁上设有至少一开孔 15 (原水口 12或浓水口 13 ) ， 且两相邻膜壳的开孔 15正对设置， 接管 6和接管密封圈 7被压紧在膜壳开孔 15周围的环形平面上， 保证各接管 6与对应 的膜壳之间的密封。
本实施例中， 该多膜壳组合单元采用捆带 4捆扎成一体。 如图 2所示， 本实施例 中， 除了最右端的膜壳可以仅设有一个原水口及最左端的膜壳可以仅设有一个浓水口 夕卜， 其它的每一膜壳的一端具有正对的二原水口， 另一端的对应位置具有正对的二浓水 口， 将各膜壳并列集束并以接管 6贯通后， 各膜壳的原水口 12呈直线贯通， 且各膜壳 的浓水口 13也呈直线贯通， 因此， 本实施例中对应于各膜壳原水口、 浓水口的位置设 置捆带 4， 以利加强连接固定的效果； 本实施例是采用柔性捆带， 捆带 4分别对应于膜 壳间的接合部而设置于组合单元的两端， 其中一捆带 4对应共享的原水口 2设置， 另一 捆带 4对应共享的浓水口 3设置。
各捆带 4进一步可设置有压力调节器 5， 压力调节器 5的结构见图 9， 其包括予紧 螺栓 51、 予紧垫块 52、 活塞 53及活塞密封圈 54。 安装时旋入予紧螺栓 51， 调整予紧 垫块 52的位置， 补偿捆带 4与组件的间隙， 使捆带 4予紧。本实施例中， 压力调节器 5 位于与共享的原水口 2或共享的浓水口 3相对的另一侧， 以便于利用膜壳内压力自动调 整捆带拉力。
具体设置时， 捆带 4可由刚性或柔性材料制成， 压力调节器 5及共用的原水口 2
(或共享的浓水口 3 )分别对应于捆带 4的两端，捆带 4两端的刚性片体与原 /浓水口螺 母及予紧垫块的对应处设有通孔， 因此， 压力调节器 5及共享的原水口 2 (或共享的浓 水口 3 ) 的外接管可由该刚性片体穿设而出。 还可在该膜壳 1与捆带 4之间设置原水口 固定螺母及浓水口固定螺母（图中未示出） ， 从而便于旋入共享的原水口 2及共享的浓 水口 3的外接管。
需要说明的是， 本发明中的捆固件可选择设置， 如果通过其他方式可以稳固地固 定该多膜壳组合单元的各膜壳， 也可不设置捆固件； 而且， 捆带的形式并不局限于此， 还可采用瓦楞形 （波浪形） 刚性捆带， 且该瓦楞形捆带的弧度及间隔较佳是与多膜壳组 合单元的各膜壳相适应， 进一步地， 还可以采用其他形式的捆固件， 例如， 以玻璃布或 玻璃纤维缠绕于该多膜壳组合单元的外周适当位置，然后进行化学反应，以捆固各膜壳。 另外， 图 9中， 该压力调节器 5的活塞包括一不锈钢的活塞本体及一活塞套， 该 活塞套较佳是以工程塑料等耐腐蚀的材料制成， 从而使得该压力调节器能够具有耐腐蚀 的特性， 但不限于此， 该活塞 53也可由其它耐腐蚀的材料一体制成。 此外， 活塞 53直 径可以灵活设置， 例如可以与共享的原浓水口 2、 3相同， 或设置该活塞 53的活塞孔的 直径可与开孔 15相同或相近， 较佳地， 该活塞 53的直径稍大于开孔 15的直径或共享 的原浓水口 2、 3的直径， 以保证使用最小的压力 （捆带拉力） 压紧各密封部位。
本实施例的多膜壳组合单元由两只以上的膜壳、 捆带、 连接管、 （共享） 原浓水 口、 压力调整机构组成。 安装时， 首先将两侧膜壳、 中部膜壳按顺序排列成一排， 在膜 壳端部开口并加工出沉孔平面的位置安放接管 6、原、浓水口固定螺母、活塞 53以及予 紧垫块 52， 然后将捆带 4由端部推入， 旋入予紧螺栓 51， 调整予紧垫块 52的位置， 补 偿捆带 4与组件的间隙， 使捆带 4予紧。然后旋入共享原浓水口 2、 3， 安装各部位密封 圈， 最后安装端部总成。 另外一端同样处理后多膜壳组合单元组装完成。
当膜壳工作时， 原水由共享的原水口 2逐次通过接管 6进入各膜壳原水端， 通过 装在膜壳内部的膜元件从另外一端 （浓水端）经过接管 6汇集， 并由共享的浓水口 3排 出。 通过捆带 4和压力调节器 5的工作， 接管 6和接管密封圈 7被压紧在膜壳 1的开 孔 15周围的环形平面上， 保证各接管 6与膜壳 1之间的密封。 同时通过设计压力调节 器 5的活塞直径 53， 可以保证使用最小的压力 （捆带拉力）压紧各密封部位。利用膜壳 内部压力以及捆带的约束， 可以实现相邻膜壳间压力自动调整， 即可以保证捆带拉力随 着膜壳内部水压变化而自动调整， 同时补偿捆带因压力产生的变形伸长， 保证接管处的 密封效果。
本实施例的该多膜壳组合单元是由四支膜壳 1 并列集束而成， 此仅为便于说明而 提出的， 并列设置的膜壳数量并不局限于此， 在具体应用时， 多采用两支以上的膜壳并 排设置来组成一具有直线分布端面的多膜壳组合单元， 以适应所需处理量要求。
由于每个多膜壳组合单元通过共享的原水口 2、 以及共享的浓水口 3与管道相连， 工程安装与维护时配管量小， 使用的卡箍数量少， 节约了资源、 降低了成本。 此外， 视 工程需要， 多膜壳组合单元既可以水平放置， 也可以垂直放置； 每个多膜壳组合单元占 地面积较小， 空间利用更加有效。
第二实施例
如图 4 所示， 其为本发明第二实施例的正视图。 如图所示， 本实施例中， 该多膜 壳组合单元的端面也呈直线分布， 与第一实施例相同。 其中， 1 为膜壳； 2为共享的原 水口； 3为共享的浓水口； 4为捆带； 5 ' 为接管卡环； 6为接管； 7为密封胶圈。 多支 膜壳 1并列集束， 采用捆带 4捆扎成一体， 每支膜壳的原水口 12、 浓水口 13分别与相 邻的一支膜壳的原水口 12、 浓水口 13通过接管 6相连， 在接管 6外露部分镶嵌有接管 卡环 5 ' ， 防止接管 6串动。 接管 6采用内接式结构， 其装设时是延伸至膜壳内壁， 并 使其两端与膜壳 1内壁相齐， 从而不会影响后续膜单元的装设； 接管 6与膜壳 1之间较 佳是采用轴向密封。 借由该方式， 组合后的各膜壳形成共享的原水口 2、 浓水口 3， 由 共享的原水口 2、 浓水口 3分别与管道相连。
多膜壳组合单元由两只以上的膜壳， 捆带， 连接管 6， （共享）原浓水口组成。 安 装时， 首先将两侧膜壳， 中部膜壳按顺序排列成一排， 在靠近膜壳端部的开孔 15处插 入接管 6和原 /浓水口固定螺母， 在将捆带 4由端部安装推入， 然后旋入共享原水口 2、 共享浓水口 3， 安装各部位密封圈， 最后安装端部总成。 另外一端同样处理后多膜壳组 合单元组装完成。
当膜壳工作时， 原水由共享原水口 2逐次通过接管 6进入各膜壳原水端并分布到 每个膜壳中， 渗透通过装在膜壳内部的膜元件（图中未示出）， 被分离为净水与浓水， 浓 水从另外一端 （浓水端） 经过接管 6汇集， 并由共享浓水口 3排出， 由于捆带 4的约 束和卡环 5 ' 的限制，接管 6和密封圈 7仅可以在膜壳端部开口 15内的密封区内作有限 的位移， 使接管 6不会在压力下脱出并保证与膜壳之间的密封。
由于每个多膜壳组合单元通过共享的原水口 2 以及共享的浓水口 3与管道相连， 工程安装与维护时配管量小， 使用的卡箍数量少， 节约了资源、 降低了成本。 此外， 每 个多膜壳组合单元占地面积较小， 空间利用更加有效。
第三实施例
如图 5 所示， 其为本发明第三实施例的正视图。 如图所示， 本实施例中， 该多膜 壳组合单元的端面大致呈矩形 （或方形） 分布。 其中， 1为膜壳； 2为共享的原水口； 3 为共享的浓水口； 4为捆带； 5 ' 为接管卡环； 6为接管； 7为密封胶圈。 多支膜壳 1并 列集束， 采用捆带 4捆扎成一体， 每支膜壳的原水口 12、 浓水口 13分别与相邻的一支 膜壳的原水口 12、 浓水口 13通过接管 6相连， 在接管 6外露部分镶嵌有接管卡环 5 ' ， 防止接管 6串动。 接管 6采用内接式结构， 其装设时延伸至膜壳内壁， 即其两端与膜壳 1内壁相齐； 接管 6与膜壳 1之间较佳是采用轴向密封。 借由该方式， 组合后的各膜壳 形成共享的原水口 2、 浓水口 3， 由共享的原水口 2、 浓水口 3分别与管道相连。
安装时， 首先将膜壳 1按顺序排列成矩形， 在膜壳端部相应开孔 15处插入接管 6 并安装卡环 5 ' 以及原、 浓水口固定螺母， 并安装捆带 4到相应位置， 然后旋入共享的 原水口 2及共享的浓水口 3， 并安装各部位密封圈， 最后安装端部总成。 另外一端同样 处理后多膜壳组合单元组装完成。
当膜壳工作时， 原水由共享的原水口 2逐次通过接管 6进入各膜壳的原水端， 渗 透过装在膜壳 1内部的膜元件， 被分离为净水与浓水， 其中浓水从另外一端 （浓水端） 经过接管 6汇集， 并由共享的浓水口 3排出。 由于捆带 4的约束和卡环的限制， 接管 6 和密封圈 7仅可以在膜壳 1靠近端部的开孔 15内的密封区内作有限的位移， 使接管 6 不会在压力下脱出并保证与膜壳之间的密封。
由于每个多膜壳组合单元通过共享的原水口 2、 以及共享的浓水口 3与管道相连， 工程安装与维护时配管量小， 使用的卡箍数量少， 节约了资源、 降低了成本。 此外， 每 个多膜壳组合单元占地面积较小， 空间利用更加有效。
第四实施例
如图 6 所示， 其为本发明第四实施例的正视图。 如图所示， 本实施例中， 该多膜 壳组合单元的端面呈六边形 （也可为其它多边形） 分布。 其中， 1 为膜壳； 2为共享的 原水口； 3为共享的浓水口； 4为捆带； 5 ' 为接管卡环； 6为接管； 7为密封胶圈。 多 支膜壳 1并列集束， 采用捆带 4捆扎成一体， 每支膜壳的原水口、 浓水口分别与相邻的 一支膜壳的原水口、 浓水口通过接管 6相连， 在接管 6外露部分镶嵌有接管卡环 5 ' ， 防止接管 6串动。 接管 6采用内接式结构， 其装设时延伸至对应的二膜壳内壁， 即其两 端分别与邻接的二膜壳 1的内壁相齐， 接管 6与膜壳 1之间可采用轴向密封。 借由该方 式， 组合后的各膜壳形成共享的原水口 2、浓水口 3， 由共享的原水口 2、浓水口 3分别 与管道相连。
安装时， 首先将膜壳 1按顺序排列成矩形， 在膜壳靠近端部的相应开孔 15内插入 接管 6并安装卡环 5 ' 以及原、 浓水口固定螺母， 并安装捆带 4到相应位置， 然后旋入 共享的原水口 2及共享的浓水口 3， 并安装各部位密封圈， 最后安装端部总成； 另外一 端同样处理后即完成了多膜壳组合单元的组装。
当膜壳工作时， 原水由共享的原水口 2逐次通过接管 6进入各膜壳的原水端， 渗 透过装在膜壳 1内部的膜元件， 被分离为净水与浓水， 其中浓水从另外一端 （浓水端） 经过接管 6汇集， 并由共享的浓水口 3排出。 由于捆带 4的约束和卡环的限制， 接管 6 和密封圈 7仅可以在膜壳 1靠近端部的开孔 15内的密封区内作有限的位移， 使接管 6 不会在压力下脱出并保证与膜壳之间的密封。 由于每个多膜壳组合单元通过共享的原水口 2 以及共享的浓水口 3与管道相连， 工程安装与维护时配管量小， 使用的卡箍数量少， 节约了资源、 降低了成本。 此外， 每 个多膜壳组合单元占地面积较小， 空间利用更加有效。
本实施例中， 该原水、 浓水贯通通道为单一流道， 但本发明不限于此， 例如该原 水、 浓水贯通通道可分别为多支流式流道， 以本实施例为例， 其中位于中央的膜壳可以 选择与其周边的每个膜壳或部分膜壳间设置贯通通道， 以减小上、 下游膜壳内的压力落 差。 另外， 如果需要在该中央膜壳上设置共享的原水口 2、 共享的浓水口 3， 则该中央 膜壳可选用端接口式结构的膜壳单元。
第五实施例
如图 7、 图 8所示， 其为本发明的一实施例采用端进共享原、 浓水口的俯视示意图 及立体示意图。
本实施例中， 各膜壳 1间原水口 12、浓水口 13的连通及密封可以参照前述实施例 以多种方式实现， 其主要特点在于多膜壳组合单元的共享的原水口 2和共享的浓水口 3 的设置方式， 前述实施例中， 该共享的原水口 2或该共享的浓水口 3是采用侧开口式膜 壳来实现的，本实施例中该共享的原水口 2和共享的浓水口 3是采用端接口式膜壳来实 现， 即并非如前述实施例设置于侧壁上， 而是将共享原水口 2设置于其中一膜壳一端的 端部堵板上， 将共享的浓水口 3设置于其中另一膜壳的另一端的端部堵板上。 通过此种 设置方式， 由于共享的原水口 2、 共享的浓水口 3设置于端部堵板上， 则无需在捆带 4 对应处的侧壁上开设供共享的原水口 2、 共享的浓水口 3穿设的穿孔， 可以简化生产、 安装工序。
与前述实施例相似， 本实施例也在多支膜壳 1的原水口 12间形成原水贯通通道， 在多支膜壳 1的浓水口 13间形成浓水贯通通道， 该原水贯通通道及浓水贯通通道分别 位于垂直于膜壳轴向的二平面内， 且至少在前述二平面内对应设置捆带 4。 不同的是， 前述实施例中， 共享的原水口 2、 共享的浓水口 3也较佳分别位于对于的平面内， 而本 实施例中， 由于共享的原水口 2、 共享的浓水口 3设于膜壳端部堵板上， 因此， 共享的 原水口 2、 共享的浓水口 3并非位于前述二平面内。
另外， 本实施例的多膜壳组合单元较佳设有捆带 4， 且捆带 4与膜壳侧壁间设有压 力调节器 5， 该压力调节器 5可采用第一实施例中的自动压力调整机构， 也可以采用手 动压力调整机构， 请参见图 10， 其与图 9中自动压力调整机构相同的部分不再详述，其 不同处主要在于： 若采用手动调整结构， 则该压力调节器无需设置活塞 53，而可用垫块 55来替代， 这样， 膜壳侧壁的对应处可不用开孔。采用该手动压力调整机构， 则在使用 时是采取手动张紧的方式实现压力调节。
本领域的技术人员根据前述说明可以了解， 本实施例的其他部分的具体设置方式 可以参照前述实施例选择其中的一项或多项特征进行组合， 因此不再赘述。
本实施例除了具有前述第一实施例的优点外， 由于共享的原水口 2、共享的浓水口
3是分别设置于两端的端部堵板上， 且采用图 10所示的手动压力调整机构， 因此， 膜壳 侧壁也无需开设对应穿孔，从而使得各膜壳的侧壁仅需设置连通所需的原水口 12、浓水 口 13， 从而进一步简化了生产、 安装工序， 降低了成本。
本发明采用多支膜壳并列集束的技术方法形成多膜壳组合单元，并将每支膜壳的原 水口、 浓水口分别与相邻的一支或多支膜壳的原水口、 浓水口通过接管相连并密封， 形 成共享的原水口、 浓水口。 每个多膜壳组合单元可以设置较少数量（如只设置一个） 与 管道装配的共享原水口、浓水口。工作时，每个多膜壳组合单元通过共享的原水口进水， 由于多支膜壳的原水口通过接管相连， 原水进入每个多膜壳组合单元后分布到每个膜壳 中。 多支膜壳并列集束， 采用捆带捆扎成一体， 每支膜壳的原水口、 浓水口分别与相邻 的一支膜壳的原水口、 浓水口通过接管相连， 接管与膜壳之间采用密封胶圈密封。 在工 作压力下， 原水渗透过膜元件， 被分离为净水与浓水。 由于多支膜壳的原水口通过接管 相连， 浓水汇合在一起， 通过共享的浓水口排出。 另外， 相对于使用不锈钢卡箍来连接 膜壳的现有技术， 本发明中的卡环及接管可以采用其他金属或非金属材料， 因此， 采用 本发明的多膜壳组合单元技术， 节省了大量卡箍， 降低了工程成本， 减少了密封点， 降 低了泄漏隐患， 减少了工程的安装量， 而且， 由于相邻膜壳间不需采用卡箍， 而仅采用 卡环隔开， 因此可以大大缩减相邻膜壳之间的间距（例如从原 50mm缩减为 5mm)， 从而 节省了装置的占地面积。
虽然本发明已以具体实施例揭示，但其并非用以限定本发明，任何本领域的技术人 员， 在不脱离本发明的构思和范围的前提下还可进行适当的变化与修改， 例如各膜壳单 元的原水口、 浓水口除了通过接管相连外， 还可通过开孔对开孔直接压紧并密封、 开孔 间胶接等形式密封连接； 对于内接式接管的具体设置方式， 可在膜壳开孔对应的内壁设 置沉孔， 该接管一端可设置法兰， 以与该沉孔结合并利用密封圈密封， 该接管的另一端 可采用螺纹连接或卡簧连接等方式与另一膜壳的内壁连接并利用密封圈密封； 各膜壳的 原水口、 浓水口数量、 设置位置关系以及捆带、 压力调节器的设置位置、 数量等均可以 根据实际要求而设置， 并不局限于前述实施例； 这些变化皆应仍属本专利涵盖的范畴。
