本发明提供的过滤膜支架，相邻振片的厚度不相同，根据流固耦合原理(固体在流体载荷的作用下产生形变或运动)，水流经振片的表面时，使振片产生振动、形成振动波，该振动波可对污水中的污物施加与水流方向相反的作用力，将污物推离支架本体的表面，污物在振动波和水流的共同作用下，保持在距离支架本体外表面的设定距离处，随着污物逐渐聚集在过滤膜支架外表面外的设定距离处，形成了过滤膜；相邻振片的厚度不相同，振片振动产生的波的频率也不相同，避免了相同频率的波叠加后相互抵消，不能将污物推离过支架本体的外表面，进而不能在距离支架本体外表面的设定距离处形成过滤膜；相邻振片之间设置有支撑件，使相邻振片之间具有足够的间隙，从而保证了有足够的水流经振片的表面，即保证了水具有足够大的载荷作用到振片上，使振片能够产生振动。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图15描述根据本发明一些实施例所述过滤膜支架。
如图1、图2和图3所示，本发明第一方面的一些实施例提供的过滤膜支架，用于水处理，包括过滤膜支架本体8，过滤膜支架本体8包括：振子单元1、连接件5和密封板4。
具体地，振子单元1包括多个依次叠放的振片2，振片2的中部设置有通孔201，多个振片的通孔201连接构成过滤膜支架本体8的清水通道3，相邻振片的厚度不相同，且振片2的厚度在0.1～0.6mm之间，以使水流过振片2的表面时振片2产生振动；连接件5依次连接多个振片2；密封板4位于过滤膜支架本体8的一端，并密封清水通道3的一端。
本发明提供的过滤膜支架，根据流固耦合原理(固体在流体载荷的作用下产生形变或运动)，水流经振片2的表面时，使振片2产生振动、形成振动波，该振动波可对待处理水中的污物施加与水流方向相反的作用力，将污物推离支架本体的表面，污物在振动波和水流的共同作用下，保持在距离支架本体外表面的设定距离处，随着污物逐渐聚集在过滤膜支架外表 面外的设定距离处，形成了过滤膜；相邻振片2的厚度不相同，振片2振动产生的波的频率也不相同，避免了相同频率的波叠加后相互抵消，不能将污物推离过支架本体的外表面，进而不能在距离支架本体外表面的设定距离处形成过滤膜。
需要说明的是，在过滤膜的厚度和密实度未达到预设值时，过滤膜不能对待处理水进行有效地过滤，此时流经振片2表面的水为待处理水；当过滤膜的厚度和密实度达到预设值时，能够对待处理水进行有效地过滤，此时流经振片2表面的水为过滤后的清水。
在本发明的一个实施例中，如图4和图5所示，振子单元1中，相邻振片2之间设置有支撑件。
另外，支撑件的高度范围为0.05mm～0.5mm，优选地，支撑件的高度为0.08mm。
在本发明的一个实施例中，如图2和图3所示，振子单元1中，相邻振片2的外边缘和内边缘均不平齐，
或者，所述振片的内边缘上设置有第一凹槽，相邻所述振片上的所述第一凹槽交错设置，和/或，所述振片的外边缘上设置有第二凹槽，相邻所述振片上的所述第二凹槽交错设置。
在上述实施例中，由于相邻振片2的内边缘不平齐，即清水通道3的内壁凹凸不平，水在清水通道3内向上流动，通过凹凸不平的内壁时，对振片2施加一作用力，使振片2产生振动，在该振动与流固耦合产生的振动、支撑件的增强振动的共同作用下，对待处理水中的污物或过滤膜施加向外的作用力(与水流施加的力相反方向的力)，同时在水流的作用下，待处理水中的污物或过滤膜保持在支架本体外表面的设定距离处。
本领域的技术人员应该理解，相邻振片的内边缘并不止限于上述的结构，只要能够保证水通过相邻振片的通孔时，使振片产生振动即可。
其中，上述实施例中振片的内边缘指的是通孔的侧壁，外边缘指的是振片的外侧壁。
在本发明的一个实施例中，如图4和图5所示，支撑件为设置在振片2上的凸起202，每一振片2上均设置有凸起202，且相邻振片2上的凸起 202相向设置。
在本发明的一个实施例中，每一振片2上均设置有多个凸起202，且多个凸起202沿振片2的周向均布。
在该实施例中，相邻振片2之间设置有凸起202，使相邻振片2之间具有足够的间隙，从而保证了有足够的水流经振片2的表面，即保证了水具有足够大的载荷作用到振片2上，使振片2能够产生振动。
此外，振片2振动时，该振片2上的凸起202会敲击与相邻的振片2，使相邻的振片2产生振动，相邻振片2振动时，其上的凸起202会反过来施加一冲击力给该振片2，增强了该振片2的振动，如此循环作用，增强了振片2振动的效果。
在本发明的一个具体实施例中，振片2为圆形振片2，通孔201为圆形通孔201；振子单元1中，相邻振片2上的凸起202在同一振片2上的投影的连线，不过振片2的圆心。
在该实施例中，水的流路不是一条直线，与水沿着振片2的径向流经振片2的表面相比，振片2上凸起202的设置，使得水流经的路径发生弯曲，因而延长了待处理水流经振片2表面的路径的长度，增加了水的载荷对振片2的作用时长，这样传递至振片2的能量越多，使得振片2的振动越剧烈。
在本发明的一个实施例中，过滤膜支架包括多个振子单元1，多个振子单元1通过连接件5相连接构成过滤膜支架本体8；多个振片2包括第一种振片2和第二种振片2，每一振子单元1中，第一种振片2和第二种振片2交替设置。
在本发明的一个实施例中，过滤膜支架还包括：出水管6和安装法兰7；出水管6与清水通道3的另一端相连通，可将清水通道3中的水排出；安装法兰7与过滤膜支架本体8的另一端相连接，用于固定安装过滤膜支架本体8。
在本发明的一个实施例中，出水管6和安装法兰7为一体式结构，出水管6位于安装法兰7的中部；连接件5为螺栓，螺栓穿过密封板4、每一振子单元1中的每一振片2后，与安装法兰7相连接。
在该实施例中，出水管6与安装法兰7为一体式结构，一方面，保证了出水管6与安装法兰7之间的连接强度，从而降低了出水管6与安装法兰7之间发生断裂的概率，进而增加了产品的使用可靠性，另一方面，出水管6与安装法兰7可一体制成，从而提高了产品的生产效率，进而降低了产品的生产制造成本。
在本发明的一个实施例中，如图6、图7和图8所示，本发明第一方面的另一些实施例提供的过滤膜支架，用于水处理，包括过滤膜支架本体8，过滤膜支架本体8包括：多个依次叠放的振片2、密封板4和连接件5。
具体地，振片2的中部设置有通孔201，多个振片2的通孔201连接构成过滤膜支架本体8的清水通道3，相邻振片2之间设置有支撑件，以使相邻振片2之间具有供水流过的间隙，且相邻振片2的厚度不相同，振片2的厚度在0.1～0.6mm之间，以使水流过振片2的表面时振片2产生振动；密封板4位于过滤膜支架本体8的一端，并密封清水通道3的一端；连接件5将多个振片2和密封板4连接在一起构成过滤膜支架本体8。
本发明提供的过滤膜支架，相邻振片2的厚度不相同，根据流固耦合原理(固体在流体载荷的作用下产生形变或运动)，水流经振片2的表面时，使振片2产生振动、形成振动波，该振动波可对污水中的污物施加与水流方向相反的作用力，将污物推离支架本体的表面，污物在振动波和水流的共同作用下，保持在距离支架本体外表面的设定距离处，随着污物逐渐聚集在过滤膜支架外表面外的设定距离处，形成了过滤膜；相邻振片2的厚度不相同，振片2振动产生的波的频率也不相同，避免了相同频率的波叠加后相互抵消，不能将污物推离过支架本体的外表面，进而不能在距离支架本体外表面的设定距离处形成过滤膜；相邻振片2之间设置有支撑件，使相邻振片2之间具有足够的间隙，从而保证了有足够的水流经振片2的表面，即保证了水具有足够大的载荷作用到振片2上，使振片2能够产生振动。
在本发明的一个实施例中，如图9和图10所示，支撑件为设置在振片2上的凸起202，每一振片2上均设置有凸起202。
在本发明的一个实施例中，如图9和图10所示，每一振片2上均设置有多个凸起202，且多个凸起202沿振片2的周向均布，且相邻振片2上的凸起202的凸出方向相同。
在该实施例中，相邻振片2之间设置有凸起202，使相邻振片2之间具有足够的间隙，从而保证了有足够的水流经振片2的表面，即保证了水具有足够大的载荷作用到振片2上，使振片2能够产生振动。
此外，振片2振动时，该振片2上的凸起202会敲击与相邻的振片2，使相邻的振片2产生振动，相邻振片2振动时，其上的凸起202会反过来施加一冲击力给该振片2，增强了该振片2的振动，如此循环作用，增强了振片2振动的效果。
在本发明的一个具体实施例中，振片2为圆形振片2，通孔201为圆形通孔201，相邻振片2上的凸起202在同一振片2上的投影的连线，不过振片2的圆心。
在该实施例中，水的流路不是一条直线，与水沿着振片2的径向流经振片2的表面相比，振片2上凸起202的设置，使得水流经的路径发生弯曲，因而延长了污水流经振片2表面的路径的长度，增加了水的载荷对振片2的作用时长，这样传递至振片2的能量越多，使得振片2的振动越剧烈。
在本发明的一个实施例中，过滤膜支架本体1中，相邻振片2的外边缘和内边缘均不平齐。
或者，过滤膜支架本体1中，振片2的内边缘上设置有第一凹槽，相邻振片2上的第一凹槽交错设置，和/或，振片2的外边缘上设置有第二凹槽，相邻振片2上的第二凹槽交错设置。
在上述实施例中，由于相邻振片2的内边缘不平齐，即清水通道8的内壁凹凸不平，水在清水通道8内向上流动，通过凹凸不平的内壁时，对振片2施加一作用力，使振片2产生振动，在该振动与流固耦合产生的振动、凸起202的增强振动的共同作用下，对污水中的污物或过滤膜施加向外的作用力(与水流施加的力相反方向的力)，同时在水流的作用下，污水中的污物或过滤膜保持在支架本体外表面的设定距离处。
在本发明的一个实施例中，多个振片2包括第一种振片203和第二种振片204，第一种振片203和第二种振片204交替设置。
采用厚度不同的第一种振片和第二种振片，则可以使得振片在流体流经其表面时，在流固耦合的作用下更容易产生振动，从而更容易形成动态膜(即所述的过滤膜)，是一种优选的实施方式。
如图11和图12所示，本发明第一方面的再一些实施例提供的过滤膜支架，用于水处理，包括多个依次叠放的振片2、上封板9、密封板4、连接件5和中空导流柱10；所述振片2的中部设置有通孔201，多个依次叠放的所述振片2的所述通孔201构成清水通道3，相邻所述振片2之间具有供流体流过的间隙；所述上封板9和所述密封板4分别设置在所述清水通道3的两端，且所述上封板9上开有与所述清水通道3的一端相连通第二通孔901，所述密封板4密封所述清水通道3的另一端；所述连接件5垂直穿过多个依次叠放的所述振片2，且所述连接件5的两端分别与所述上封板9和所述密封板4相连接；所述中空导流柱10设置在所述清水通道3内，将所述清水通道3分割成所述中空导流柱10壁外的第一通道301和所述中空导流柱10壁内的第二通道302，且所述中空导流柱10的壁上设置有将所述第一通道301和所述第二通道302相连通的第三通孔101，所述第二通孔901仅与所述第二通道302相连通。
本发明提供的过滤膜支架，采用中空导流柱将清水通道分割成第一通道和第二通道，中空导流柱的壁上开有第三通孔，且第二通孔仅与所述第二通道相连通，使得进入清水通道的流体首先进入第一通道内，然后通过中空导流柱壁上的第三通孔流入第二通道，再由第二通道流出，这使得清水通道内部的流体为层流状态，易于动态膜的快速形成，并可使动态膜保持维持状态和致密后的正常脱落，提高了流体组分过滤和分离的效率。解决了现有技术中的问题、实现本发明的发明目的。
在本发明的一个实施例中，如图12和图13所示，中空导流柱10的两端分别与所述上封板9和所述密封板4固定连接，将多个依次叠放的所述振片2连接成一体。
将中空导流柱的两端分别与上封板和密封板固定连接，则使得多个振片采用中空导流柱来连接和固定成一体，使得连接件不受拉应力、仅仅对振片起支撑作用，减小了连接件的变形，便于整个过滤膜支架的拆卸、维修，并提高过滤膜支架的使用寿命。当然，采用连接件来连接和固定多个振片也是可以的，不再赘述。
在本发明的一个实施例中，如图12、图13和图14所示，所述中空导流柱10的上端开口、下端封闭，所述中空导流柱10的两端分别与所述上封板9和所述密封板4相螺接，且所述中空导流柱10的上端穿过所述第二 通孔901。
所述中空导流柱的上端开口、下端封闭，两端与所述上封板和密封板采用螺接的固定连接方式，且中空导流柱的上端穿过所述第二通孔，便于整个过滤膜支架的生产、组装和维修。当然，本领域技术在本发明的启发性，可以理解中空导流柱的两端与上封板和密封板采用焊接、铆接等方式固定连接，也可以实现本发明的发明目的。
在本发明的一个实施例中，如图12、图13和图14所示，所述中空导流柱10的壁上开有多个所述第三通孔101，所述第一通道301内的流体经所述第三通孔101流入所述第二通道302内。
本实施例中，如图12和图13所示，所述第二通孔51可以自上向下规则设置，也可不规则设置；通孔的形状可以是如图12和图13所示的圆形也可以是如图14所示的腰形、或者其它形状，但是设置成均匀的圆形，更有利于第二通道302内层流的形成，是一种优选实施方案。
在本发明的一个实施例中，如图12和图13所示，所述密封板4的外表面为凸弧形或中间高两边低的阶梯形，内表面为凹弧形。
密封板的外表面为凸弧形或中间高两边低的阶梯形，可减小涡流，使其不会对动态膜的建立和维持造成影响，减小其对罐体内部整体液流的影响，使液流更加平稳。而平板形的密封板，当液流经过密封板外边缘时，会产生涡流，影响动态膜的形成和维持，另外也会使罐体内部液流造成紊乱；密封板3的内表面为凹圆弧形，可有效减弱内部紊流，增加流体稳定性。
在本发明的一个实施例中，如图14所示，还包括垫片11，所垫片11分别设置在所述上封板9和所述密封板4与所述振片2之间、以及多个所述振片2的中部。
设置垫片可增加密封效果，且该垫片可固定于连接件和/或中空导流柱上，可增加整个过滤膜支架的稳定性和强度。
在本发明的一个实施例中，相邻所述振片2的厚度不相同，所述振片2的厚度在0.1mm～1.2mm之间，且相邻所述振片2之间设置有支撑件。结构与上述实施例中的图7-8、图10的所示相同，不再重复。
在本发明的一个实施例中，所述支撑件为设置在所述振片2上的凸起202，所述凸起202的高度范围为0.05mm-0.5mm。结构与上述实施例中的 图7-8、图10的所示相同，不再重复。
在本发明的一个实施例中，相邻所述振片2的外端面不平齐，且相邻所述振片2的内端面也不平齐。结构与上述实施例中的图7-8、图10的所示相同，不再重复。
由于相邻振片的内边缘不平齐，使得即清水通道的壁面凹凸不平，流体在清水通道内流动时，对振片产生作用力，使振片产生振动，在该振动与固液耦合产生的振动的共同作用下，对动态膜施加朝向过滤膜支架外的作用力(与流体施加力的方向相反)，则在动态过滤膜支外表面外的设定距离更容易形成动态膜；同样，相邻振片的外边缘不平齐，也便于动态膜的形成：相邻振片的外端面不平齐使过滤膜支架的外表面形成沟槽，当流体由过滤膜支架的外表面经由振片间的缝隙流入清水通道时，就会撞击振片，并在沟槽处形成湍流，湍流对流体中的粒子施加与主体流体方向相反的作用力，使得粒子进行小幅度的往复运动并停留在过滤膜支架表面附近。这样，粒子在沟槽中的湍流和主体流体流动的共同作用下，停留在距离过滤膜支架外表面的设定距离处，随着更多粒子逐渐聚集在过滤膜支架外表面外的设定距离处，则在过滤膜支架外表面设定的距离处逐渐形成所述动态膜。
在本发明的一个实施例中，如图8所示，多个所述振片2包括厚度不同的第一种振片203和第二种振片204，所述第一种振片203和所述第二种振片204交替设置。结构与上述实施例中的图8的所示相同，不再重复。
采用厚度不同的第一种振片和第二种振片，则可以使得振片在流体流经其表面时，在固液耦合的作用下更容易产生振动，从而更容易形成动态膜，是一种优选实施方式。
如图15所示，本发明第二方面的实施例提供的过滤膜的生成方法，包括：
步骤1001，向待处理水中加入添加剂；
步骤1002，将待处理水通过上述任一项所述的过滤膜支架，则待处理水通过相邻振片之间的缝隙流过振片的表面进入清水通道时，振片产生振动、形成振动波，振动波对过滤膜支架外表面附近的污物施加与水流方向相反的作用力，且污物在振动波的作用力和水流作用力下，保持在过滤膜支架外表面附近，污物逐渐聚集，在过滤膜支架外表面附近形成过滤膜。
在本发明的一个具体实施例中，在步骤1002中，污物为絮状污物。
在本发明的一个具体实施例中，添加剂为絮凝剂。
在本发明中，术语“多个”则指两个或两个以上，除非另有明确的限定。术语“安装”、“相连”、“连接”、“固定”等术语均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接；“相连”可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
