Description

Technical Field

[0001] The invention relates to a high-efficiency filtering membrane component, belonging to the field of filtering technology, and in particular to a filtering membrane component capable of realizing high-efficiency stripping of impurities. Background Art

[0002] Existing plate-and-frame filter presses are widely used in the field of solid-liquid separation. The filter cavity formed by the filter cloth between the plates and frames uses pressure to separate the liquid from the solid. The equipment consists of multiple plates and frames and filter cloths, which are stacked on each other. The liquid flows through the filter cloth under pressure, and the solid particles are intercepted by the filter cloth, thereby filtering the liquid. However, due to the high pressure in the filtration process, the filtered material usually adheres to the surface of the filter cloth, making it more difficult to clean the filter cloth.

[0003] In traditional plate and frame filter presses, the solid matter accumulated on the filter cloth needs to be manually removed after filtration. Especially when there are a large number of plates and frames, the cleaning work becomes extremely arduous and time-consuming. This not only reduces the cleaning efficiency, but also increases labor costs. The cleaning methods in the prior art usually rely on manual intervention, which makes it difficult to achieve efficient and automated cleaning, especially during high-pressure filtration, when the deposited matter on the filter cloth is often relatively solid and more difficult to remove.

[0004] In addition, traditional plate and frame filter presses mostly rely on a static filtration process and lack the technical means to effectively clean and condition the filter cloth after filtration. Existing equipment fails to provide an effective mechanism to reduce the adhesion between the filter cloth and the filtered material during the filtration process, resulting in inefficiencies in the cleaning and maintenance process. Summary of the invention

[0005] Based on this, it is necessary to provide a high-efficiency filtration membrane assembly to address the problem of low impurity stripping efficiency of current filtration membrane assemblies.

[0006] The above purpose is achieved through the following technical solutions: A high-efficiency filtration membrane component, comprising: Plate and frame assembly; A coupling assembly is arranged at the horizontal center of the plate-frame assembly, and the coupling assembly is at least formed with a through hole; a first rotating assembly, rotatably connected to the coupling assembly; Wherein, the first rotating assembly is rotatable when the adjacent plate-frame assemblies are separated; a second rotating assembly, rotatably connected to the first rotating assembly; Furthermore, the center position of the filter membrane of the plate-frame assembly is connected to the second rotating assembly; The second rotating assembly is controlled by the rotation of the first rotating assembly and has a first movement, and is controlled by the elastic force of the filter membrane and has a second movement, wherein the first movement and the second movement are opposite rotations; Under the interaction of the first movement and the second movement, the surface of the filter membrane switches between a smooth state and a wrinkled state.

[0007] Preferably, the coupling component comprises: a coupling axis located at the horizontal center of the plate-frame assembly; Wherein, the coupling shaft is formed with the through hole; A coupling cavity is arranged concentrically with the coupling axis; Wherein, the first rotating assembly is rotationally connected to the coupling shaft; Wherein, at least a portion of the first rotating component is located inside the coupling cavity.

[0008] Preferably, the first rotating assembly comprises: A first rotating part, sleeved on the coupling shaft and meshingly connected with the coupling shaft; A second rotating part, connected to the circumferential wall surface of the first rotating part and located in the coupling cavity; A linkage part is arranged along the circumferential wall surface of the second rotating part, and is used for driving the second rotating component to perform a first movement.

[0009] Preferably, the first rotating assembly comprises: An elastic member, sleeved on the coupling shaft and located between the first rotating part and the coupling cavity; Wherein, the elastic member is configured to apply an axial force to the first rotating part away from the coupling cavity.

[0010] Preferably, the second rotating assembly comprises: a third rotating portion, rotatably connected to a circumferential wall surface of the first rotating portion; The second linkage part is arranged along the circumferential direction of the end surface of the second rotating part toward the coupling cavity; Wherein, the second linkage part and the first linkage part have a contact state and a separation state; The contact state is configured such that the third rotating part executes the first movement of the second rotating component, serving as a specific execution component of the movement; The separation state is configured such that the third rotating part executes the second movement of the second rotating component and serves as a specific execution component of the movement.

[0011] Preferably, the coupling cavity is formed with a plurality of arc-shaped grooves along the circumferential direction; Wherein, the second linkage part passes through the arc-shaped groove and forms the contact state with the first linkage part.

[0012] Preferably, the second rotating assembly comprises: Two mounting rings, sleeved on the circumferential wall surface of the first rotating part; Wherein, the third rotating part is rotatably connected between the two mounting rings.

[0013] Preferably, the first linkage part is a spring sheet, and the second linkage part is a rod; Wherein, the length direction of the spring sheet is perpendicular to the length direction of the rod.

[0014] Preferably, the spring piece has a vibration generating structure; Wherein, the vibration generating structure is configured to allow the spring to vibrate in the separated state and continue to vibrate until the contact state.

[0015] Preferably, the vibration generating structure comprises: A groove, provided on the end surface of the spring sheet facing the rod; Furthermore, there are a plurality of grooves, which are arranged in a direction perpendicular to the length of the spring sheet.

[0016] The beneficial effects of the present invention are: When the filter membrane surface is converted to a wrinkled state, the morphology of the filter membrane surface changes, and solid impurities are entrained into the wrinkled part of the filter membrane surface. In the wrinkled state, the contact area between the solid impurities and the filter membrane surface increases, so that the original adhesion of the solid impurities is disturbed, and the contact force between the filter membrane surface and the impurities is weakened. When the filter membrane surface returns to a smooth state, the interference caused by the wrinkles disappears, but the adhesion between the filter membrane surface and the solid impurities has been significantly reduced due to the disturbance in the wrinkled state. The solid impurities are no longer as tightly attached to the filter membrane surface as in the smooth state, and are therefore easier to peel off.

[0017] By switching between these states, the bonding force between the solid impurities and the surface of the filter membrane is repeatedly weakened, making it easier for the solid impurities to fall off, ultimately improving the self-cleaning effect and filtration efficiency of the filter membrane.

[0023] like Figures 1 to 3 As shown, the first embodiment of the present invention provides a high-efficiency filtration membrane assembly, comprising: Plate frame assembly 1; The coupling component 2 is arranged at the horizontal center of the plate-frame component 1, and the coupling component 2 is at least formed with a through hole 201; A first rotating component 3, rotatably connected to the coupling component 2; Wherein, the first rotating assembly 3 can rotate when the adjacent plate-frame assembly 1 is separated; A second rotating assembly 4, rotatably connected to the first rotating assembly 3; Furthermore, the center position of the filter membrane 5 of the plate-frame assembly 1 is connected to the second rotating assembly 4; The second rotating component 4 is controlled by the rotation of the first rotating component 3 and has a first movement, and is controlled by the elastic force of the filter membrane 5 and has a second movement, wherein the first movement and the second movement are opposite rotations; Under the interaction of the first movement and the second movement, the surface of the filter membrane 5 switches between a smooth state and a wrinkled state.

[0024] In this embodiment, the plate-frame assembly 1 is the main part of the high-efficiency filtration membrane assembly, which is responsible for accommodating the filter membrane 5 and bearing the stress during the high-pressure filtration process. The plate-frame assembly 1 includes a plurality of interconnected plate frames, and a through hole 201 is provided inside each plate frame for liquid to pass through. The filter membrane 5 is installed on two opposite end faces of the plate frame. When filtering the liquid, solid impurities are trapped in the filtration space formed by the adjacent filter membrane 5. In order to ensure a good filtering effect, the plate-frame assembly 1 has high sealing performance and strength, and can withstand the pressure during the filtration process.

[0025] like Figure 4 and Figure 5 As shown, the plate-frame assembly 1 also includes a displacement mechanism for causing the multiple plates and frames to approach and squeeze each other, and to move away from each other. Of course, the plate-frame filter press is relatively mature in the prior art, and will not be described in detail here. This embodiment only improves the mechanical structure for how to efficiently strip solid impurities.

[0026] like Figure 6 and Figure 7 As shown, the first rotating assembly 3 is connected to the coupling assembly 2 and is arranged at the center of the plate frame assembly 1. When the adjacent plate frame assemblies 1 are separated, the first rotating assembly 3 will rotate, triggering the action of the second rotating assembly 4. The main function of the first rotating assembly 3 is to trigger the rotation and promote the first movement of the second rotating assembly 4.

[0027] The second rotating assembly 4 is rotationally connected to the first rotating assembly 3, and participates in the change of the state of the filter membrane 5 through linkage with the filter membrane 5. When the first rotating assembly 3 is started, the second rotating assembly 4 shows a first movement, resulting in wrinkles on the surface of the filter membrane 5. Specifically, the edge of the filter membrane 5 is mounted to the circumference of the plate frame assembly 1, such as the plate frame assembly 1 is provided with an embedded groove in the circumference, the groove may contain a sealing strip or a pressure strip, and the edge of the filter membrane 5 is embedded in the groove. A through hole is provided at the center of the filter membrane 5, and the hole edge of the through hole is mounted on the second rotating assembly 4. Therefore, when the second rotating assembly 4 performs the first movement, that is, rotates, through its fixed connection with the central through hole of the filter membrane 5, the filter membrane 5 will produce a torsion or stretching effect, so that its surface changes from a flat state to a wrinkled state. The wrinkled state helps to remove solid impurities attached to the surface of the filter membrane 5. Specifically, the first movement of the second rotating assembly 4 triggers the deflection of the edge of the through hole, resulting in the concentration of force in the central area of ​​the filter membrane 5, which gradually pushes the surface of the filter membrane 5 into a wrinkled state. Such wrinkles can effectively reduce the adhesion between solid impurities and the surface of the filter membrane 5, thereby facilitating the subsequent impurity cleaning step.

[0028] In this embodiment, the filter membrane 5 adopts a fiber-reinforced elastic membrane, and the elasticity, tensile strength and filtration efficiency of the membrane are significantly improved by embedding a high-strength fiber reinforcement layer in the elastic matrix. For example, the filter membrane 5 can use an enhanced composite PVDF membrane, whose matrix is ​​composed of an enhanced polyvinylidene fluoride (PVDF) material and is embedded with a polyester fiber (PET) grid reinforcement layer. It has excellent chemical stability and mechanical properties and is suitable for high-intensity sewage filtration scenarios. Due to the elastic properties of the filter membrane 5, the surface of the filter membrane 5 will gradually return to a smooth state. During this process, the second rotating component 4 will undergo a second movement, which helps the surface of the filter membrane 5 to return to a smooth state.

[0029] That is to say, the elastic force of the first rotating component 3 and the filter membrane 5 causes the second rotating component 4 to cycle between the first movement and the second movement, and the surface of the filter membrane 5 also cycles between the smooth state and the wrinkled state, which helps to reduce the adhesion between the surface of the filter membrane 5 and the solid impurities. Specifically: In the smooth state, the surface of the filter membrane 5 is relatively uniform and smooth, and solid impurities may be easily adhered to the surface of the filter membrane 5 due to the strong surface tension and adhesion of the filter membrane 5.

[0030] When the surface of the filter membrane 5 is converted into a pleated state, the morphology of the surface of the filter membrane 5 changes, and this morphology change is mainly used to reduce the adhesion between the solid impurities and the surface of the filter membrane 5, so that the solid impurities are more easily separated from the surface of the filter membrane 5. Specifically, through the formation of pleats, the contact area and contact tightness between the surface of the filter membrane 5 and the solid impurities are reduced, thereby optimizing the cleaning efficiency and making the hardened filter cake easier to separate and peel off.

[0031] When the surface of the filter membrane 5 returns to a smooth state, the interference caused by the wrinkles disappears, but the adhesion between the surface of the filter membrane 5 and the solid impurities has been significantly reduced due to the disturbance in the wrinkled state. The solid impurities are no longer tightly attached to the surface of the filter membrane 5 as in the smooth state, and are therefore more easily peeled off.

[0032] By switching between these states, the bonding force between the solid impurities and the surface of the filter membrane 5 is repeatedly weakened, making it easier for the solid impurities to fall off, thereby ultimately improving the self-cleaning effect and filtering efficiency of the filter membrane 5 .

[0033] like Figures 1 to 3 As shown, the second embodiment of the present invention provides a high-efficiency filtration membrane assembly, and based on the above embodiment, the coupling assembly 2 includes: The coupling axis 202 is located at the horizontal center of the plate-frame assembly 1; Wherein, the coupling shaft 202 is formed with a through hole 201; The coupling cavity 203 is arranged concentrically with the coupling axis 202; Wherein, the first rotating assembly 3 is rotationally connected to the coupling shaft 202; At least a portion of the first rotating component 3 is located inside the coupling cavity 203 .

[0034] In this embodiment, the coupling shaft 202 is arranged at the horizontal center of the plate frame assembly 1 and plays a connecting and supporting role. The coupling shaft 202 ensures that the first rotating assembly 3 can rotate around it, thereby triggering the movement of the second rotating assembly 4.

[0035] A through hole 201 is formed on the coupling shaft 202, which is mainly used for the entry of filtrate. The through hole 201 itself is not a main structural part of the present invention, but serves as a necessary channel in the liquid filtration process to allow liquid to enter and perform the filtration operation.

[0036] The coupling cavity 203 is arranged concentrically with the coupling shaft 202, and accommodates a portion of the first rotating assembly 3. The coupling cavity 203 ensures that the rotation path of the first rotating assembly 3 is clear, and helps to reduce external interference, and improve the stability and reliability of the rotation. The coupling cavity 203 provides a stable rotation space for the first rotating assembly 3, so that it can smoothly drive the second rotating assembly 4 to perform a predetermined movement.

[0037] The first rotating component 3 is connected to the coupling shaft 202 by rotation, ensuring that the rotation of the first rotating component 3 can effectively trigger and adjust the movement mode of the second rotating component 4, thereby realizing the switching of the surface state of the filter membrane 5 (mutual conversion between smoothness and wrinkles).

[0038] In a specific implementation, the coupling cavity 203 is an annular cavity surrounding the coupling axis 202 .

[0039] like Figure 4 , Figure 7 and Fig.11 As shown, the third embodiment of the present invention provides a high-efficiency filtration membrane assembly, and on the basis of the above embodiment, the first rotating assembly 3 includes: The first rotating part 301 is sleeved on the coupling shaft 202 and meshed with the coupling shaft 202; The second rotating part 302 is connected to the circumferential wall of the first rotating part 301 and is located in the coupling cavity 203; The linkage part 303 is arranged along the circumferential wall surface of the second rotating part 302, and is used to drive the second rotating component 4 to perform the first movement.

[0040] In this embodiment, the first rotating part 301 is a sleeve, and is meshed with the coupling shaft 202. When the adjacent plate frame assemblies 1 are separated, the interaction force between the two disappears or weakens, and the first rotating part 301 rotates in response to the separation process, thereby driving the second rotating part 302 to rotate synchronously, and finally driving the second rotating assembly 4 to perform the first movement.

[0041] The second rotating part 302 drives the second rotating assembly 4 to perform the first movement, promoting the switching of the surface of the filter membrane 5 from the smooth state to the wrinkled state, and increasing the peeling effect between the solid impurities and the surface of the filter membrane 5. Through the elastic recovery effect, the surface of the filter membrane 5 can be restored to a smooth state, reducing the adhesion of solid impurities, thereby achieving the purpose of cleaning the membrane surface. This structure enables the filter membrane 5 to more efficiently clean the solid impurities attached to the surface during operation, thereby improving the filtering effect and reducing the need for manual cleaning.

[0042] In a specific embodiment, the second rotating portion 302 is a rotating ring, and is sleeved on the first rotating portion 301, that is, the circumferential wall of the sleeve.

[0043] like Figures 1 to 7 , Fig.10 As shown, the fourth embodiment of the present invention provides a high-efficiency filtration membrane assembly, and on the basis of the above embodiment, the first rotating assembly 3 includes: The elastic member 304 is sleeved on the coupling shaft 202 and is located between the first rotating portion 301 and the coupling cavity 203; The elastic member 304 is configured to apply an axial force to the first rotating portion 301 away from the coupling cavity 203 .

[0044] In this embodiment, the elastic member 304 is, for example, a compression spring, which exerts an axial force to always maintain elastic support for the first rotating portion 301. The force enables the first rotating portion 301 to move in an axial direction away from the coupling cavity 203.

[0045] Since the first rotating part 301 is meshed with the coupling shaft 202, when the adjacent plate frame assemblies 1 are separated, the first rotating part 301 will immediately respond and move in the axial direction away from the coupling cavity 203. Through this axial movement, the second rotating assembly 4 is driven to perform the first movement through the linkage part 303.

[0046] In this embodiment, a push ring 305 is further included, and the elastic member 304 applies the above-mentioned axial force to the first rotating part 301 through the push ring 305. The push ring 305 is rotatably connected to the first rotating part 301, and is fixedly connected to the elastic member 304. The push ring 305 is rotatably connected to the first rotating part 301, so as to ensure that the axial force of the elastic member 304 can be stably transmitted to the first rotating part 301, thereby ensuring that the first rotating part 301 can smoothly move and rotate axially.

[0047] The configuration of the elastic member 304 enables the first rotating part 301 to quickly respond to the separation action of the plate-frame assembly 1 , to promptly perform axial movement and synchronous rotation, thereby pushing the second rotating assembly 4 to perform the first movement, further facilitating the cleaning and maintenance of the filter membrane 5 .

[0048] The elastic member 304 always applies an axial force to ensure that the movement process of the first rotating part 301 is more stable, reducing unstable factors caused by external disturbances or internal friction of the system, and improving the working reliability of the system.

[0049] like Figures 4 to 7 As shown, the fifth embodiment of the present invention provides a high-efficiency filtration membrane assembly, and on the basis of the above embodiment, the second rotating assembly 4 includes: A third rotating portion 401, rotatably connected to a circumferential wall surface of the first rotating portion 301; The second linkage part 402 is arranged along the circumferential direction of the end surface of the second rotating part 302 toward the coupling cavity 203; The linkage part 2 402 and the linkage part 1 303 have a contact state and a separation state; The contact state is configured such that the third rotating part 401 performs the first movement of the second rotating component 4 and serves as a specific execution component of the movement; The separation state is configured such that the third rotating portion 401 executes the second movement of the second rotating component 4 and serves as a specific execution component of the movement.

[0050] In this embodiment, the first rotating part 301 and the third rotating part 401 are connected to each other by rotation. When the adjacent plate frame assemblies 1 are separated, the first rotating part 301 starts to rotate in response to the separation action, thereby driving the linkage part 1 303 and the linkage part 2 402 to enter a contact state. In this state, the third rotating part 401 performs the first movement.

[0051] Specifically, when the first rotating part 301 rotates, the second linkage part 402 is brought into contact with the first linkage part 303 through the transmission effect of the first linkage part 303, so that the third rotating part 401 enters the first motion state. At this time, wrinkles appear on the surface of the filter membrane 5, which reduces the adhesion between the solid impurities and the membrane surface, thereby facilitating the peeling and cleaning of the solid impurities.

[0052] When the third rotating part 401 performs the first movement, wrinkles are generated on the surface of the filter membrane 5, which effectively reduces the adhesion between solid impurities and the membrane surface, thereby improving the self-cleaning ability of the membrane and reducing impurity residues. This process automatically starts the movement process when the plate and frame assembly 1 is separated, realizes automatic cleaning of the surface of the filter membrane 5, reduces manual intervention, and improves work efficiency and stability of the filtering equipment.

[0053] On the other hand, when the linkage part 1 303 rotates to be separated from the linkage part 2 402, it enters the separation state, and the third rotating part 401 is no longer driven by the linkage part 1 303, but is controlled by the elastic force of the filter membrane 5 (i.e., the force for restoring the surface of the filter membrane 5 to a smooth state). In this case, the third rotating part 401 performs the second movement, i.e., the surface of the filter membrane 5 is restored from a wrinkled state to a smooth state.

[0054] Specifically, in the separated state, the elastic properties of the filter membrane 5 play a role, causing the membrane surface to rebound and return to a smooth state. At this time, the second movement of the third rotating part 401 helps to smooth the surface of the filter membrane 5, further reducing the adhesion between the solid impurities and the membrane surface, so that the surface of the filter membrane 5 remains clean.

[0055] By switching between the smooth state and the wrinkled state, the surface of the filter membrane 5 can achieve self-cleaning, reduce the accumulation of solid impurities, reduce the frequency of manual cleaning, and improve the filtration efficiency and long-term stability of the equipment.

[0056] In general, it helps the filter membrane to maintain high efficiency during the filtration process, effectively avoids impurity accumulation, increases the service life of the membrane, and reduces maintenance costs.

[0057] like Figures 8 to 10 As shown, the sixth embodiment of the present invention provides a high-efficiency filtration membrane assembly, and based on the above embodiment, the coupling cavity 203 is formed with a plurality of arc grooves 2031 along the circumferential direction; The second linkage part 402 passes through the arc groove 2031 and is in contact with the first linkage part 303 .

[0058] In this embodiment, the arc grooves 2031 are evenly distributed in the circumferential direction of the coupling cavity 203, and are used to guide the movement path of the second linkage part 402. When the second linkage part 402 is pushed to the edge of a certain arc groove 2031 by the first linkage part 303, the second linkage part 402 will be stopped, that is, the second linkage part 402 is prevented from sliding further along the arc groove 2031. This stopping effect helps to promote the separation of the first linkage part 303 and the second linkage part 402, thereby controlling the movement of the third rotating part 401.

[0059] When the second linkage part 402 is pulled back to the other edge of the arc groove 2031 due to the elastic force of the filter membrane 5, the second linkage part 402 will be stopped again. At this time, the edge of the arc groove 2031 provides a stable support position, providing an initial position for the next contact between the second linkage part 402 and the first linkage part 303. In this way, the surface of the filter membrane 5 can be smoothly switched between a smooth state and a wrinkled state.

[0060] The arc groove 2031 ensures the stable contact and separation state of the linkage part 2 402 and the linkage part 1 303 during the movement, making the movement process more accurate and controllable. The arc groove 2031 can not only guide the precise position of the linkage part 2 402, but also effectively utilize the elastic force of the filter membrane 5, making the state switching of the filter membrane 5 smoother and avoiding excessive friction and damage. Through regular state switching, the peeling of solid impurities can be promoted, thereby improving the self-cleaning effect of the filter membrane 5 and reducing the frequency and difficulty of manual cleaning.

[0061] The seventh embodiment of the present invention provides a high-efficiency filtration membrane assembly, and based on the above embodiment, the first linkage part 303 is a spring sheet, and the second linkage part 402 is a rod; The length direction of the spring piece is perpendicular to the length direction of the rod.

[0062] In this embodiment, the linkage part 303 is in the form of a spring sheet, which is elastic and can be deformed within a predetermined range. When the spring sheet is working, it will drive the rod to move accordingly, thereby promoting the movement of other components, especially driving the third rotating part 401 to rotate.

[0063] The second linkage part 402 is a rod, which is perpendicular to the length direction of the spring sheet. During operation, the rod is pushed by the spring sheet, thereby pushing the third rotating part 401 to rotate. When the rod moves circumferentially to the edge of the arc groove 2031, it will be stopped to prevent it from continuing to rotate. At this time, the elastic properties of the spring sheet will cause it to deform and gradually break away from the contact with the rod and enter a separated state.

[0064] The spring sheet and the rod are in a contact state and a separation state during operation. In the contact state, the spring sheet pushes the rod, driving the third rotating part 401 to perform a predetermined first movement. When the rod is stopped by the arc groove 2031, the spring sheet gradually breaks away from the contact with the rod due to deformation and enters a separation state. At this time, the third rotating part 401 is affected by the elastic force of the filter membrane 5 and performs a second movement.

[0065] The switching of the contact and separation states between the spring piece and the rod ensures the motion transmission between the linkage part 1 303 and the linkage part 2 402. In particular, after the rod is stopped by the arc groove 2031, the deformation of the spring piece can avoid the movement being completely stopped, but gradually break away from the contact with the rod, ensuring the smoothness and continuity of the motion process.

[0066] Through the deformation of the spring sheet, it can adapt to a wider range of working conditions. After the rod is blocked, the deformation of the spring sheet avoids the instantaneous stagnation of the force, so that the movement can continue within a certain range, thereby effectively improving the adaptability of the system.

[0067] In the separated state, the contact between the spring and the rod is reduced, thereby reducing friction and wear, and extending the service life of the device. Especially during frequent motion switching, the deformation of the spring can effectively reduce the damage caused by friction. Due to the elastic effect of the spring, it can smoothly switch between the contact state and the separation state, optimizing the transmission of force. After the spring is deformed, it gradually separates from the contact with the rod, which can buffer the impact of the movement and avoid mechanical shock caused by sudden force transmission.

[0068] like Figure 1 and Figure 2 As shown, the eighth embodiment of the present invention provides a high-efficiency filtration membrane assembly, and on the basis of the above embodiment, the second rotating assembly 4 includes: Two mounting rings 403 are sleeved on the circumferential wall surface of the first rotating part 301; The third rotating portion 401 is rotatably connected between the two mounting rings 403 .

[0069] In this embodiment, the two mounting rings 403 play a restraining role, ensuring that the third rotating part 401 can stably rotate and sleeve on the circumferential wall of the first rotating part 301, and preventing the third rotating part 401 from axial movement. It can effectively prevent the third rotating part 401 from unnecessary displacement during the rotation process, and maintain the accuracy and stability of its movement. At the same time, the configuration of the mounting ring 403 ensures that the third rotating part 401 is always on the correct track when rotating, avoiding potential problems caused by unstable movement.

[0070] like Fig.11 As shown, the ninth embodiment of the present invention provides a high-efficiency filtration membrane assembly, and based on the above embodiments, it also has a vibration generating structure 6; The vibration generating structure 6 is configured to allow the spring to vibrate in the separated state and continue to vibrate until it reaches the contact state.

[0071] In this embodiment, the vibration generating structure 6 of the spring piece is configured to allow the spring piece to generate continuous vibration when the spring piece is in a separated state. Specifically, the vibration generating structure 6 includes: A groove is provided on the end surface of the spring piece facing the rod; Furthermore, there are a plurality of grooves, which are arranged perpendicular to the length direction of the spring sheet.

[0072] When the shrapnel recovers from the compressed state (contact state) to the free state (separated state), the elastic potential energy generated in the material will be released, which will trigger the free vibration of the shrapnel. Moreover, the structure of the slot introduced into the shrapnel changes the local stress distribution of the shrapnel, causing it to produce asymmetric deformation when releasing the elastic potential energy, thereby triggering periodic vibration. In addition, the other end of the shrapnel is fixed by a flexible support point, so that it forms a cantilever beam-like structure in the separated state. The flexible support point can absorb part of the vibration energy and prevent the vibration from decaying rapidly. The shrapnel is made of high elastic modulus materials (such as stainless steel spring sheets or composite elastic materials) to ensure that it can continue to maintain vibration performance during repeated deformation.

[0073] These vibrations will be maintained until the shrapnel contacts the rod (i.e., the second linkage part 402) again. When the shrapnel contacts the rod again, the vibration is transmitted to the rod, and further transmitted to the filter membrane 5. Specifically, when the vibrating end of the shrapnel contacts the rod, the kinetic energy of the end of the shrapnel is transmitted to the rod through the contact point. Due to the high rigidity of the rod, that is, the high rigidity of the contact point between the two, the rod can receive most of the vibration energy (i.e., kinetic energy transfer). Moreover, when the vibration frequency of the shrapnel is high, a series of short high-frequency shocks will be formed at the moment of contact, which can be partially absorbed by the rod and further transmitted to the filter membrane. The rod needs to be selected from a material with a high elastic modulus and high kinetic energy transfer efficiency, such as a high-strength aluminum alloy. This material can minimize the energy absorption during contact, thereby enhancing the vibration transmission effect.

[0074] In this way, the effect of vibration transmission can enhance the stripping effect of solid impurities on the surface of the filter membrane 5 , reduce the adhesion between the solid impurities and the surface of the filter membrane 5 , and thus improve the cleaning efficiency of the filter membrane 5 .

[0075] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
