Description

流体通道及其固液分离设备 技术领域
本发明涉及一种流体通道及其直驱式固液分离设备，该固液分离设备属于离心机领域。
背景技术
在实验室小试和中试研究过程中，最常用的固液分离设备主要是布氏漏斗加抽滤瓶的组合以及各种规格的离心机，其中布氏漏斗加抽滤瓶的组合仅适合实验室小试研究，为了模拟生产中的实际情况，并为生产提供必要的离心分离操作数据，更值得推荐的是离心机。
目前常用的离心机都是采用驱动装置(主要是电机)和固液分离装置(主要是液体收集腔和从动离心单元)分置、再组装而成，其离心转鼓(相当于从动离心单元)都是机械固定于传动轴上，导致离心转鼓的拆装以及离心设备的清洁验证比较困难，而且设备显得过于复杂笨重、噪音和振动太大、制造工艺复杂、维修不方便等各种缺陷或弊端，不能完全满足实验室小试和中试中固液混合物彻底分离的需要。
发明内容
发明目的：
本发明的目的在于提供一种固液离心分离和液体的收集、输送与电机转子、定子中的任一者或两者为一体化电绝缘设计的流体通道及其直驱式固液分离设备。
技术方案：
为了克服现有固液分离设备存在的各种缺陷或弊端，本发明提供了一种固液离心分离和液体的收集、输送与电机转子、定子中的任一者或两者为一体化电绝缘设计的流体通道及其直驱式固液分离设备，该固液分离设备结构上的一个主要特点是具有一个由流体通道旋转部与静止部组成的流体输送通道，以下对本发明作详细说明。
根据本发明所述的流体通道，其包括：
(1)流体通道旋转部，所述流体通道旋转部隔着气隙布置于定子总成所围成的空腔内，其包括：
至少一个转子单元，所述转子单元通过与适配的定子单元之间的电磁相互作用产生的旋转力使流体通道旋转部绕电机轴作旋转运动；

转子单元支撑件，所述转子单元支撑件包括：
从动离心单元锁定结构和/或锁定单元，用于锁定和/或解锁从动离心单元并使从动离心单元与流体通道旋转部同速同轴旋转；
承载转子单元的大致为圆筒状的主体部(如101或107所指示位置)；
封闭或半封闭主体部底端的底部(103)；
作为可选结构、位于主体部顶端且中央具料液入口的盖部；
所述转子单元支撑件或流体通道旋转部通过如下轴连接结方式中的任一种与电机轴发生关系：
通过位于转子单元支撑件底部中央的电机轴安装孔(104)；
通过安装支架(202)，所述安装支架与底部和电机轴固定连接，或与底部和/或电机轴为一体结构；
电机轴与转子单元支撑件或流体通道旋转部为一体结构(图9和图10)；
其中与流体通道静止部A相适配的流体通道旋转部，其转子单元支撑件底部与流体通道静止部A环形凹腔相对应的位置具有用于将流体引导至环形凹腔的具导流通孔的导流结构，所述导流通孔兼作锁定从动离心单元的锁定结构；
(2)流体通道静止部，其选自如下所述A、B中的任一种：
流体通道静止部A(图3)：包括由环形凹腔内环(304)和环形凹腔外环(301)两个圆筒所围成的竖截面为“U”型的环形凹腔(310)以及位于该环形凹腔底部的使液体流向液体收集瓶的排液管道(309)，所述环形凹腔敞口端与位于转子单元支撑件底部上用于将流体引导至流体通道静止部A环形凹腔的具有导流通孔(102)的导流结构密封连接；
流体通道静止部B(图4)：包括收集由液体收集腔引导而来的液体的漏斗口和使液体流向液体收集瓶的漏斗颈，所述漏斗口边缘与液体收集腔内壁(101)密封连接，所述漏斗颈穿过电机空心轴并且其末端固定于定子单元支撑件基座部、轴承座、端盖三者中任一者上；
所述流体通道静止部A位于定子单元支撑件基座部、电机轴承座、端盖三者中任一者上或与其中任一者一体成型，比如采用金属铝或钢、铁等材料将静止部A与电机轴承座、定子单元支撑件基座部和/或定子单元支撑件外壳部一体铸造或冲压成型(图8)，更优选将流体通道静止部A与定子单元一体模制成型为定子总成(图10)，这样更有利于定子总成的塑封成型以及绝缘等级的提高，对易燃易爆固液混合物的离心分离特别有效。
具体地，所述流体通道由旋转部离心液体收集腔及其底部上正对环形凹腔位置的导流结构与静止部A中的环形凹腔经过密封对接组成，由液体收集腔富集的离心液体在自身重力的作用下，经过转子单元支撑件底部上的导流通孔(102)被输送至静止部A的环形凹腔(310)内，最后通过位于该环形凹腔底部的管道(309)使液体流向液体收集瓶。
具体地，所述流体通道由旋转部液体收集腔与静止部B中的漏斗口边缘经过密封对接组成，由液体收集腔富集的离心液体在自身重力的作用下，经过漏斗口(402、406)和连通口(403)被输送至漏斗颈(405)内，最后通过漏斗颈使液体流向液体收集瓶。所述部静止部B中的漏斗口包括呈圆盘状(402)或漏斗状(406)两种结构形式，优选漏斗口状的结构形式，这样在重力作用下更有利于液体的流出，图4A图示了具圆盘状漏斗口的静止部B，图4B图示了具漏斗状漏斗口的静止部B。

(4)永磁体、转子导条、端环以及铁芯的组合；
其中所述永磁体包括但不限于钕铁硼磁铁、钐钴磁铁、铝镍钴磁铁、铁氧体磁铁、塑磁磁铁中的任一种或它们两者或多者之间的组合。所述转子单元结构优选铁芯及永磁体的组合，次选转子导条、端环以及铁芯的组合，此两种组合结构相较于其它结构更方便生产，而具无铁芯导电绕组的转子单元比较适合微量离心机的制造，也可选择其它结构的转子单元。
根据本发明所述的流体通道，所述静止部B面向液体收集腔敞口端一侧的漏斗口具有从其边缘向其中心延伸的凸起(401)和/或凹槽，具体而言，包括直线状的凸起和/或凹槽以及曲线状的凸起和/或凹槽两种情况，这些凸起和/或凹槽可以快速降低使液体作旋转运动的离心力的作用，从而使液体更快经由漏斗颈到达液体收集瓶，提高液体的排出效率，图4(包括图4A和图4B)图示了这种凸起以及位于相邻凸起之间的凹槽。
根据本发明所述的流体通道，所述转子单元支撑件底部与流体通道静止部A环形凹腔相对应的位置具有以电机轴中心线为轴心的，包括但不限于选自如下(5)～(8)所述四种导流结构中的任一种：

(8)正对流体通道静止部A环形凹腔内环和外环位置且位于转子单元支撑件底部的环形内凹槽和环形外凹槽以及位于环形内凹槽和环形外凹槽之间的底部(图7D)；
其中所述以电机轴中心线为轴心沿圆周方向间隔分布的导流通孔位于上述四种导流结构中的任一种上，最外缘的导流通孔位于转子单元支撑件主体部和底部的大致交界处，所述导流通孔也可以兼作从动离心单元的锁定结构。由于位于底部中央圆锥形凸台的阻隔以及离心力的作用，液体会被甩向液体收集腔内侧壁，并在自身重力作用下通过导流通孔流向流体通道静止部A的环形凹腔，图6A图示了具圆锥形凸台、电机轴安装孔和导流通孔的流体通道旋转部，图6B为图6A旋转180°后的轴测图，其图示了具环形内凹槽和环形外凹槽底部的流体通道旋转部。
