The limitations of the example.
下面参照附图描述根据本发明一些实施例的污水处理***和污水处理 方法。Hereinafter, a sewage treatment system and sewage treatment according to some embodiments of the present invention will be described with reference to the accompanying drawings. method.
本发明一方面的实施例提供了一种污水处理***，如图1和图2所示，包括：上水装置、污水处理罐2和排水装置。An embodiment of the present invention provides a sewage treatment system, as shown in Figures 1 and 2, comprising: a water supply device, a sewage treatment tank 2, and a drainage device.
其中，所述上水装置用于将污水输入所述污水处理罐2中；Wherein the water supply device is used to input sewage into the sewage treatment tank 2;
所述污水处理罐2内设有过滤膜支架20和过滤膜自清洁装置，所述过滤膜支架20对由污物构成的过滤膜进行支撑，所述过滤膜可对所述污水进行过滤，所述过滤膜自清洁装置可使所述过滤膜振动、部分脱落，防止所述过滤膜板结；The sewage treatment tank 2 is provided with a filter membrane support 20 and a filter membrane self-cleaning device, and the filter membrane support 20 supports a filter membrane composed of dirt, and the filter membrane can filter the sewage. The filter membrane self-cleaning device can vibrate and partially detach the filter membrane to prevent the filter membrane from being knotted;
所述排水装置用于将过滤后的清水排出。The drain device is for discharging the filtered fresh water.

在过滤过程中，过滤膜的厚度和密实度逐渐增大，当过滤膜的厚度和密实度超过预设值时，过滤膜的过水效率降低，当过滤膜的过水量低于进水口的进水量时，污水处理罐内的液位逐渐升高，当污水处理罐内的液位达到预设高度时，过滤膜自清洁装置工作，使过滤膜振动，部分脱落，导致过滤膜的厚度和密实度减小，使得过滤膜可重新高效地对污水进行过滤，使污水的进入量与过滤膜的过水量保持平衡。During the filtration process, the thickness and compactness of the filtration membrane gradually increase. When the thickness and compactness of the filtration membrane exceed the preset value, the water filtration efficiency of the filtration membrane is lowered, and when the water filtration amount of the filtration membrane is lower than the inlet of the water inlet. When the amount of water is used, the liquid level in the sewage treatment tank gradually increases.

在一具体示例中，如图4所示，所述支架本体包括振子单元200、连接件203和密封板202。In a specific example, as shown in FIG. 4, the bracket body includes a vibrator unit 200, a connector 203, and a sealing plate 202.
其中，如图7所示，所述振子单元200包括多个依次叠放的振片201，所述振片201的中部设置有第一通孔2010，多个所述振片201的所述第一通孔2010相连通，构成所述振子单元200的清水通道2000，相邻所述振片201的厚度不相同，且所述振片201的厚度在0.1～0.6mm之间，以使水流过所述振片201的表面时，所述振片201产生振动；As shown in FIG. 7 , the vibrator unit 200 includes a plurality of diaphragms 201 stacked in sequence, and a central portion of the diaphragm 201 is provided with a first through hole 2010, and the plurality of the diaphragms 201 are A through hole 2010 is connected to form a clear water passage 2000 of the vibrator unit 200, the thickness of the adjacent diaphragm 201 is different, and the thickness of the diaphragm 201 is between 0.1 and 0.6 mm, so that water flows through When the surface of the diaphragm 201 is used, the diaphragm 201 generates vibration;

在本发明的上述实施例中，振子单元中，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振动)，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。In the above embodiment of the present invention, in the vibrator unit, the thickness of the adjacent diaphragms is different, according to the fluid-solid coupling principle (the solid forms deformation or vibration under the action of the fluid load), when the water flows through the surface of the diaphragm, The vibrating piece generates vibration and forms a vibration wave, which can apply a force opposite to the direction of the water flow to the dirt in the sewage, pushing the dirt away from the surface of the bracket body, and the dirt is vibrating Under the joint action of wave and water flow, it is kept at a set distance from the outer surface of the stent body, and a filter film is formed as the dirt gradually gathers at a set distance outside the outer surface of the filter membrane holder.
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。The thickness of the adjacent diaphragms is different, and the frequency of the waves generated by the vibration of the diaphragm is also different, which avoids the waves of the same frequency superimposed and cancel each other, and cannot push the dirt away from the outer surface of the bracket body, and thus cannot be at the distance bracket. A filter membrane is formed at a set distance of the outer surface of the body.
需要说明的是，在过滤膜的厚度和密实度未达到预设值时，过滤膜不能对污水进行有效地过滤，此时流经振片表面的水为污水；当过滤膜的厚度和密实度达到预设值时，能够对污水进行有效地过滤，此时流经振片表面的水为过滤后的清水。It should be noted that when the thickness and compactness of the filter membrane have not reached the preset value, the filter membrane cannot effectively filter the sewage, and the water flowing through the surface of the diaphragm is sewage; when the thickness and compactness of the membrane are When the preset value is reached, the sewage can be effectively filtered, and the water flowing through the surface of the diaphragm is filtered water.
进一步，所述支架本体包括多个依次叠放的所述振子单元200，所述连接件203将多个所述振子单元200连接起来，每一所述振子单元200中部的清水通道2000连通，构成了两端开口的清水腔，密封板202通过连接件203固定在支架本体的下端，并将清水腔的下端口密封，经过滤膜过滤后的清水可进入清水腔，并从清水腔的上端口排出。Further, the bracket body includes a plurality of the vibrator units 200 stacked in sequence, the connecting member 203 connects the plurality of vibrator units 200, and the clear water passages 2000 in the middle of each of the vibrator units 200 are connected to each other.

在一具体示例中，所述支撑件为设置在所述振片201上的凸起2011。In a specific example, the support member is a protrusion 2011 disposed on the diaphragm 201.
振片上设置有凸起，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。The vibration piece is provided with a protrusion so that there is sufficient clearance between the adjacent vibration pieces, thereby ensuring that sufficient water flows through the surface of the vibration piece, that is, the water has a sufficient load to act on the vibration piece, so that the vibration piece can Generate vibration.
此外，振片振动时，振片上的凸起会敲击与相邻的振片，使相邻的振片产生振动，相邻振片振动时，其上的凸起会反过来施加一冲击力给该振片，增强了该振片的振动，如此循环作用，增强了振片振动的效果。In addition, when the diaphragm vibrates, the protrusion on the diaphragm will strike the adjacent diaphragm, causing the adjacent diaphragm to vibrate. When the adjacent diaphragm vibrates, the protrusion on the diaphragm will in turn exert an impact force. The vibration of the diaphragm is enhanced for the diaphragm, and the circulation effect is enhanced to enhance the vibration of the diaphragm.
在本发明的一具体示例中，如图6所示，所述振片201上均设置有多个所述凸起2011，多个所述凸起2011沿所述振片201的周向均布设置；In a specific example of the present invention, as shown in FIG. 6, the plurality of protrusions 2011 are disposed on the diaphragm 201, and the plurality of protrusions 2011 are uniformly disposed along the circumferential direction of the diaphragm 201;
进一步，所述振片201为圆形振片，所述第一通孔2010为圆形通孔，所述振子单元200中，相邻所述振片201上的所述凸起2011在同一所述振片201上的投影的连线不过所述振片201的圆心。Further, the diaphragm 201 is a circular diaphragm, and the first through hole 2010 is a circular through hole. In the vibrator unit 200, the protrusions 2011 adjacent to the diaphragm 201 are in the same place. The line connecting the projections on the vibrating piece 201 is not the center of the diaphragm 201.
与水沿着振片的径向流经振片的表面相比，振片上凸起的设置，使得 水流经的路径发生弯曲，因而延长了污水流经振片表面的路径的长度，增加了水的载荷对振片的作用时长，这样传递至振片的能量越多，使得振片的振动越剧烈。Compared with the surface of water flowing through the diaphragm in the radial direction of the diaphragm, the convex arrangement on the diaphragm makes The path through which the water flows is bent, thereby prolonging the length of the path of the sewage flowing through the surface of the diaphragm, increasing the duration of the action of the water load on the diaphragm, so that the more energy transmitted to the diaphragm, the more severe the vibration of the diaphragm .

由于相邻振片的第一通孔的孔径不相同，即清水通道的内壁凹凸不平，水在清水通道内向上流动，通过不同孔径的振片时，对振片施加一作用力，使振片产生振动，在该振动与流固耦合产生的振动、凸起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(即与水流方向相反的力)，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。Since the apertures of the first through holes of the adjacent diaphragms are different, that is, the inner wall of the clear water passage is uneven, the water flows upward in the clear water passage, and when the diaphragms of different apertures are passed, a force is applied to the diaphragm to make the diaphragm Producing vibration, applying an outward force (ie, a force opposite to the direction of water flow) to the dirt or filter membrane in the sewage under the combined action of the vibration and the vibration generated by the fluid-solid coupling Under the action of the water stream, the dirt or filter membrane in the sewage is maintained at a set distance on the outer surface of the stent body.
在本发明的另一具体示例中，所述振片201的内边缘上设置有第一凹槽(图中未示出)，相邻所述振片201上的所述第一凹槽交错设置，使得振片201的内边缘不平齐；和/或，所述振片201的外边缘上设置有第二凹槽(图中未示出)，相邻所述振片201上的所述第二凹槽交错设置，使得振片201的外边缘不平齐。In another specific example of the present invention, the inner edge of the diaphragm 201 is provided with a first groove (not shown) adjacent to the first groove on the diaphragm 201. So that the inner edge of the diaphragm 201 is not flush; and/or the outer edge of the diaphragm 201 is provided with a second groove (not shown) adjacent to the first portion of the diaphragm 201 The two grooves are staggered so that the outer edge of the diaphragm 201 is not flush.

在本发明的上述具体实施例中，在过滤过程中，过滤膜的厚度和密实度逐渐增大并超过预设值，使得过滤膜的过水效率降低，过滤膜的过水量低于进水口的进水量时，污水处理罐内的液位逐渐升高，当污水流经气隔板的第四通孔，并压缩空气腔内的空气时，使空气产生波动，空气的波动可通过气隔板上的第四通孔传导至污水中，使污水产生轻微的振动，进而带动污水中的过滤膜产生振动，部分脱落，使得过滤膜的厚度和密实度减小，使得过滤膜可重新高效地对污水进行过滤，使污水的进入量与过滤膜的过水量保持平衡。In the above specific embodiment of the present invention, during the filtration process, the thickness and the density of the filtration membrane gradually increase and exceed a preset value, so that the water filtration efficiency of the filtration membrane is lowered, and the water passing amount of the filtration membrane is lower than that of the water inlet.

In order to have a gap between the adjacent diaphragms 201 through which the water supply flows, and the thickness of the adjacent diaphragms 201 is different, the thickness of the diaphragm 201 is between 0.1 and 0.6 mm so that water flows through the surface of the diaphragm 201. The vibration plate 201 generates vibration; the sealing plate 202 is located at one end of the filter film holder body, and seals the water. One end of the passage 2000; the connecting member 203 connects the plurality of diaphragms 201 and the sealing plate 202 to form a filter membrane holder body.
本发明提供的过滤膜支架，相邻振片201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201的表面时，使振片201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201的厚度不相同，振片201振动产生的波的频率也不相同，既能避免了相同频率的波叠加后相互抵消，又能将污物推离至支架本体外表面外，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201之间设置有支撑件，使相邻振片201之间具有足够的间隙，从而保证了有足够的水流经振片201的表面，即保证了水具有足够大的载荷作用到振片201上，使振片201能够产生振动。According to the filter film holder provided by the present invention, the thickness of the adjacent diaphragms 201 is different, and according to the fluid-solid coupling principle (the solid forms deformation or movement under the action of the fluid load), when the water flows through the surface of the diaphragm 201, the diaphragm 201 is made. Vibrating and generating a vibration wave, which can apply a force opposite to the direction of the water flow to the dirt in the sewage, pushing the dirt away from the surface of the bracket body, and the dirt is kept under the joint action of the vibration wave and the water flow. At a set distance from the outer surface of the stent body, a filter film is formed as the dirt gradually gathers at a set distance outside the outer surface of the filter membrane holder; the thickness of the adjacent diaphragm 201 is different, and the vibration of the diaphragm 201 is generated. The frequency of the wave is also different, which can avoid the wave overlap of the same frequency and cancel each other out, and can push the dirt away from the outer surface of the stent body, and thus can not form a filter at a set distance from the outer surface of the stent body. Membrane; a supporting member is disposed between adjacent diaphragms 201 to ensure sufficient clearance between adjacent diaphragms 201, thereby ensuring that sufficient water flows through the surface of the diaphragm 201, thereby ensuring sufficient water. The load on the vibration plate 201, the vibrator 201 can vibrate sheet.
需要说明的是，在过滤膜的厚度和密实度未达到预设值时，过滤膜不能对污水进行有效地过滤，此时流经振片表面的水为污水；当过滤膜的厚度和密实度达到预设值时，能够对污水进行有效地过滤，此时流经振片表面的水为过滤后的清水。It should be noted that when the thickness and compactness of the filter membrane have not reached the preset value, the filter membrane cannot effectively filter the sewage, and the water flowing through the surface of the diaphragm is sewage; when the thickness and compactness of the membrane are When the preset value is reached, the sewage can be effectively filtered, and the water flowing through the surface of the diaphragm is filtered water.
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。Further, the height of the support member ranges from 0.05 mm to 0.5 mm, and preferably, the height of the support member is 0.08 mm.
在本发明的一个实施例中，如图13和图14所示，支撑件为设置在振片201上的凸起2011，每一振片201上均设置有凸起2011。In one embodiment of the present invention, as shown in FIGS. 13 and 14, the support member is a protrusion 2011 disposed on the diaphragm 201, and each of the diaphragms 201 is provided with a protrusion 2011.
在本发明的一个实施例中，如图12和图14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。In one embodiment of the present invention, as shown in FIG. 12 and FIG. 14, each of the diaphragms 2 is provided with a plurality of protrusions 202, and the plurality of protrusions 202 are evenly distributed along the circumferential direction of the diaphragm 2, and adjacent to each other. The projections 202 on the diaphragm 2 have the same convex direction.
在该实施例中，相邻振片201之间设置有凸起2011，使相邻振片201之间具有足够的间隙，从而保证了有足够的水流经振片201的表面，即保证了水具有足够大的载荷作用到振片201上，使振片201能够产生振动。In this embodiment, the protrusions 2011 are disposed between the adjacent diaphragms 201 so that there is sufficient clearance between the adjacent diaphragms 201, thereby ensuring that sufficient water flows through the surface of the diaphragm 201, that is, water is secured. A sufficiently large load acts on the diaphragm 201 to enable the diaphragm 201 to generate vibration.
此外，振片201振动时，该振片201上的凸起2011会敲击与相邻的振片201，使相邻的振片201产生振动，相邻振片201振动时，其上的凸起2011 会反过来施加一冲击力给该振片201，增强了该振片201的振动，如此循环作用，增强了振片201振动的效果。In addition, when the diaphragm 201 vibrates, the protrusions 2011 on the diaphragm 201 will strike the adjacent diaphragm 201, causing the adjacent diaphragm 201 to vibrate. When the adjacent diaphragm 201 vibrates, the protrusion thereon is convex. From 2011 In turn, an impact force is applied to the diaphragm 201, which enhances the vibration of the diaphragm 201, and the circulation action enhances the vibration of the diaphragm 201.
在本发明的一个具体实施例中，如图13和14所示，振片201为圆形振片，第一通孔2010为圆形通孔，相邻振片201上的凸起2011在同一振片201上的投影的连线，不过振片201的圆心。In a specific embodiment of the present invention, as shown in FIGS. 13 and 14, the diaphragm 201 is a circular diaphragm, the first through hole 2010 is a circular through hole, and the protrusions 2011 on the adjacent diaphragm 201 are in the same The line connecting the projections on the diaphragm 201 is the center of the diaphragm 201.
在该实施例中，水的流路不是一条直线，与水沿着振片的径向流经振片的表面相比，振片上凸起的设置，使得水流经的路径发生弯曲，因而延长了污水流经振片表面的路径的长度，增加了水的载荷对振片的作用时长，这样传递至振片的能量越多，使得振片的振动越剧烈。In this embodiment, the flow path of the water is not a straight line, and the convex arrangement on the vibrating piece causes the path through which the water flows to bend, thereby prolonging, as compared with the surface in which the water flows through the diaphragm in the radial direction of the diaphragm. The length of the path of the sewage flowing through the surface of the diaphragm increases the duration of the action of the water on the diaphragm, so that the more energy is transmitted to the diaphragm, the more severe the vibration of the diaphragm.
在本发明的一个实施例中，如图11和图14所示，过滤膜支架本体中，相邻振片201的外边缘和内边缘均不平齐；或者，过滤膜支架本体中，振片201的内边缘上设置有第一凹槽，相邻振片201上的第一凹槽交错设置，和/或，振片201的外边缘上设置有第二凹槽，相邻振片201上的第二凹槽交错设置。In an embodiment of the present invention, as shown in FIG. 11 and FIG. 14, in the filter film holder body, the outer edge and the inner edge of the adjacent diaphragm 201 are not flush; or, in the filter film holder body, the diaphragm 201 The inner edge is provided with a first groove, the first groove on the adjacent diaphragm 201 is staggered, and/or the outer edge of the diaphragm 201 is provided with a second groove on the adjacent diaphragm 201. The second grooves are staggered.
在上述实施例中，由于相邻振片的内边缘不平齐，即清水通道的内壁凹凸不平，水在清水通道内向上流动，通过凹凸不平的内壁时，对振片施加一作用力，使振片产生振动，在该振动与流固耦合产生的振动、凸起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。In the above embodiment, since the inner edge of the adjacent diaphragm is not flush, that is, the inner wall of the clear water passage is uneven, the water flows upward in the clear water passage, and when passing through the uneven inner wall, a force is applied to the diaphragm to cause vibration. The sheet generates vibration, and under the combined action of the vibration and the vibration generated by the fluid-solid coupling, an outward force is applied to the dirt or the filter film in the sewage (the force opposite to the force applied by the water flow) At the same time, under the action of water flow, the dirt or filter membrane in the sewage is kept at a set distance of the outer surface of the stent body.
在本发明的一个实施例中，如图14所示，多个振片201包括第一种振片2013和第二种振片2014，第一种振片2013和第二种振片2014交替设置。In one embodiment of the present invention, as shown in FIG. 14, the plurality of diaphragms 201 include a first type of diaphragm 2013 and a second type of diaphragm 2014, and the first type of diaphragm 2013 and the second type of diaphragm 2014 are alternately arranged. .
本领域的技术人员应该理解，相邻振片的内边缘不平齐并不限于上述的结构，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。It should be understood by those skilled in the art that the inner edge of the adjacent diaphragm is not flush and is not limited to the above structure, as long as the water can be vibrated by passing through the through hole of the adjacent diaphragm.
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。Wherein, the inner edge of the diaphragm in the above embodiment refers to the side wall of the through hole, and the outer edge refers to the outer side wall of the diaphragm.

It can be understood that the two ends of the hollow guide column 207 are fixedly connected to the upper sealing plate 206 and the sealing plate 202 by welding, riveting or the like, and the object of the invention can also be achieved.
在本发明的一个实施例中，如图16、图17和图18所示，所述中空导流柱207的壁上开有多个所述第六通孔2071，所述第一通道2001内的流体经所述第六通孔2071流入所述第二通道2002内。In one embodiment of the present invention, as shown in FIG. 16, FIG. 17, and FIG. 18, a plurality of the sixth through holes 2071 are opened in the wall of the hollow guide column 207, and the first passage 2001 is inside.

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。The outer surface of the sealing plate has a convex arc shape or a low step shape on both sides of the middle, which can reduce the eddy current, so that it does not affect the establishment and maintenance of the dynamic membrane, and reduces the influence on the overall liquid flow inside the tank body. Make the flow more stable. The flat plate-shaped sealing plate, when the liquid flows through the outer edge of the sealing plate, will generate eddy current, which will affect the formation and maintenance of the dynamic film, and also cause the liquid flow inside the tank to be disordered; the inner surface of the sealing plate is a concave arc Shape, can effectively reduce internal turbulence and increase fluid stability.
在本发明的一个实施例中，如图18所示，还包括垫片208，所垫片208分别设置在所述上封板206和所述密封板202与所述振片201之间、以及多个所述振片201的中部。In an embodiment of the present invention, as shown in FIG. 18, further including a spacer 208 disposed between the upper sealing plate 206 and the sealing plate 202 and the diaphragm 201, and a plurality of middle portions of the diaphragm 201.
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。The gasket is provided to increase the sealing effect, and the gasket can be fixed to the joint and/or the hollow guide column to increase the stability and strength of the entire filter membrane holder.
在本发明的一个实施例中，相邻所述振片201的厚度不相同，所述振片201的厚度在0.1mm～1.2mm之间，且相邻所述振片201之间设置有支撑件。In an embodiment of the present invention, the thickness of the adjacent diaphragms 201 is different, the thickness of the diaphragm 201 is between 0.1 mm and 1.2 mm, and a support is disposed between the adjacent diaphragms 201. Pieces.
振片的厚度在上述范围内，保证了流体与振片的外端面有足够的接触面，便于动态膜的形成和保持；相邻振片之间设置有支撑件，可使相邻振片之间具 有足够的间隙，也利于动态膜的形成和维持。The thickness of the vibrating piece is within the above range, which ensures that the fluid has sufficient contact surface with the outer end surface of the vibrating piece to facilitate the formation and maintenance of the dynamic film; the supporting piece is disposed between the adjacent vibrating pieces, so that the adjacent vibrating piece can be Inter There is enough clearance to facilitate the formation and maintenance of dynamic membranes.
在本发明的一个实施例中，所述支撑件为设置在所述振片上的凸起2011，所述凸起2011的高度范围为0.05mm-0.5mm。In an embodiment of the invention, the support member is a protrusion 2011 disposed on the diaphragm, and the protrusion 2011 has a height ranging from 0.05 mm to 0.5 mm.
采用振片上的凸起作为支撑件，一方面保证了支撑件与振片之间的连接强度，从而降低了支撑件与振片之间发生了断裂的概率，从而提高了产品的可靠性；另一方面凸起可与振片一体成型，从而提高了产品生产效率，进而降低了产品的生产制造成本。The use of the protrusion on the vibration piece as the support member ensures the connection strength between the support member and the vibration piece on the one hand, thereby reducing the probability of breakage between the support member and the vibration piece, thereby improving the reliability of the product; On the one hand, the protrusion can be integrally formed with the vibration piece, thereby improving the production efficiency of the product, thereby reducing the manufacturing cost of the product.
在本发明的一个实施例中，相邻所述振片201的外端面不平齐，且相邻所述振片201的内端面也不平齐。In an embodiment of the invention, the outer end faces of the adjacent diaphragms 201 are not flush, and the inner end faces of the adjacent diaphragms 201 are not flush.
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动态膜(即所述过滤膜)。Since the inner edge of the adjacent diaphragm is not flush, the wall surface of the clear water passage is uneven, and when the fluid flows in the clear water passage, a force is generated on the diaphragm to cause the diaphragm to vibrate, and the vibration is coupled with the solid-liquid coupling. Under the action of vibration, applying a force to the dynamic membrane outside the filter membrane stent (in the opposite direction to the force applied by the fluid), the dynamic membrane is more easily formed at a set distance outside the outer surface of the dynamic filter membrane; likewise, the phase The outer edge of the adjacent diaphragm is not flush, and the dynamic film is also formed: the outer end surface of the adjacent diaphragm is not flush, so that the outer surface of the filter membrane bracket forms a groove when the fluid passes from the outer surface of the filter membrane bracket through the diaphragm When the gap flows into the clear water passage, it will strike the diaphragm and form a turbulent flow at the groove. The turbulence exerts a force on the particles in the fluid opposite to the direction of the body fluid, causing the particles to reciprocate in a small amplitude and stay in the filter membrane holder. Near the surface. Thus, under the combined action of the turbulent flow in the groove and the fluid flow of the body, the particles stay at a set distance from the outer surface of the filter membrane holder, and the set distance of more particles gradually gathers outside the outer surface of the filter membrane holder. At the same time, a dynamic film (ie, the filter film) is gradually formed at a distance set by the outer surface of the filter membrane holder.
在本发明的一个实施例中，多个所述振片201包括厚度不同的第一种叠2013和第二种振片2014，所述第一种振片2013和所述第二种振片2014交替设置。In one embodiment of the present invention, the plurality of the diaphragms 201 include a first stack 2013 and a second diaphragm 2014 having different thicknesses, the first diaphragm 2013 and the second diaphragm 2014 Alternate settings.
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。在本发明的一具体实施例中，如图1所示，所述上水装置包括固渣池11和第一泵送装置12。The first type of diaphragm and the second type of diaphragm having different thicknesses can make the diaphragm vibrate more easily under the action of solid-liquid coupling when the fluid flows through the surface, thereby making it easier to form a dynamic film. A preferred embodiment. In a specific embodiment of the invention, as shown in FIG. 1, the water supply device includes a slag pool 11 and a first pumping device 12.
