Description

Technical Field

[0001] The present invention relates to an efficient filter membrane module, belonging to the field of filtration technology, and particularly to a filter membrane module capable of efficiently stripping impurities. Background Art

[0002] Existing plate and frame filter presses are widely used in the field of solid-liquid separation. Through the filter chamber formed by filter cloth between the plates and frames, liquid and solid are separated by pressure. This device consists of multiple plates and frames, which are stacked on top of each other. Through the liquid flowing through the filter cloth under pressure, solid particles are intercepted by the filter cloth, thus realizing the filtration of the liquid. However, due to the high pressure during the filtration process, the filtered material usually adheres to the surface of the filter cloth, increasing the difficulty of cleaning the filter cloth.

[0003] In traditional plate and frame filter presses, the solid substances accumulated on the filter cloth need to be manually removed after filtration. Especially when there are a large number of plates and frames, the cleaning work becomes extremely heavy and time-consuming. This not only reduces the cleaning efficiency but also increases the labor cost. The existing cleaning methods usually rely on manual intervention and are difficult to achieve efficient and automated cleaning. Especially during the high-pressure filtration process, the substances deposited on the filter cloth are often relatively firm and more difficult to remove.

[0004] In addition, most traditional plate and frame filter presses rely on a static filtration process and lack technical means for effectively cleaning the filter cloth and surface adjustment after filtration. The existing equipment fails to provide an effective mechanism during the filtration process to reduce the adhesion force between the filter cloth and the filtered material, resulting in low efficiency during the cleaning and maintenance process. Summary of the Invention

[0005] Based on this, in view of the problem of low impurity stripping efficiency of the current filter membrane module, it is necessary to provide an efficient filter membrane module.

[0011] Wherein, the first rotating assembly is rotatable when the adjacent plate and frame assemblies are separated;

[0012] A second rotating assembly, rotatably connected to the first rotating assembly;

[0013] Moreover, the central position of the filter membrane of the plate-and-frame assembly is connected to the second rotating assembly;

[0014] The second rotating assembly is controlled by the rotation of the first rotating assembly and has a first motion, and is also controlled by the elastic force of the filter membrane and has a second motion, wherein the first motion and the second motion are opposite rotations;

[0015] Under the interaction of the first motion and the second motion, the surface of the filter membrane switches between a smooth state and a wrinkled state.

[0016] Preferably, the coupling assembly includes:

[0017] A coupling shaft located at the horizontal center of the plate-and-frame assembly;

[0018] Wherein, the through hole is formed on the coupling shaft;

[0019] A coupling cavity arranged concentrically with the coupling shaft;

[0020] Wherein, the first rotating assembly is rotationally connected to the coupling shaft;

[0021] Wherein, at least a part of the first rotating assembly is located inside the coupling cavity.

[0022] Preferably, the first rotating assembly includes:

[0023] A first rotating part sleeved on the coupling shaft and meshingly connected to the coupling shaft;

[0024] A second rotating part connected to the circumferential wall surface of the first rotating part and located inside the coupling cavity;

[0025] A linkage part arranged along the circumferential wall surface of the second rotating part for driving the second rotating assembly to perform the first motion.

[0026] Preferably, the first rotating assembly includes:

[0027] An elastic member sleeved on the coupling shaft and located between the first rotating part and the coupling cavity;

[0028] Wherein, the elastic member is configured to apply an axial force away from the coupling cavity to the first rotating part.

[0029] Preferably, the second rotating assembly includes:

[0030] A third rotating part rotationally connected to the circumferential wall surface of the first rotating part;

[0031] The second linkage part is circumferentially arranged along the end face of the second rotating part facing the coupling cavity;

[0032] Wherein, the second linkage part and the first linkage part have a contact state and a separation state;

[0033] The contact state is configured such that the third rotating part executes the first movement of the second rotating assembly and serves as the specific executing component for this movement;

[0034] The separation state is configured such that the third rotating part executes the second movement of the second rotating assembly and serves as the specific executing component for this movement.

[0035] Preferably, a plurality of arc-shaped grooves are formed circumferentially on the coupling cavity;

[0036] Wherein, the second linkage part passes through the arc-shaped groove and forms the contact state with the first linkage part.

[0046] Moreover, there are a plurality of the grooves and they are arranged along the direction perpendicular to the length direction of the spring piece.

[0047] The beneficial effects of the present invention are:

[0048] When the surface of the filter membrane is converted into a wrinkled state, the morphology of the filter membrane surface changes, and solid impurities are carried 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 force of the solid impurities is disturbed, and the contact force between the filter membrane surface and the impurities weakens. When the surface of the filter membrane returns to a smooth state, the interference caused by the wrinkles disappears, but the adhesion force between the filter membrane surface and the solid impurities has been significantly reduced due to the disturbance in the wrinkled state, and the solid impurities no longer adhere tightly to the filter membrane surface as in the smooth state, so they are more easily peeled off.

[0049] Through this state switching, the adhesion force between the solid impurities and the filter membrane surface is repeatedly weakened, making the solid impurities easier to fall off, and ultimately improving the self-cleaning effect and filtration efficiency of the filter membrane.

Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature.

[0066] As Figures 1 to 3 shown, the first embodiment of the present invention provides a high-efficiency filter membrane module, including:

[0067] Plate frame assembly 1;

[0068] The coupling component 2 is disposed at the horizontal center of the plate frame component 1, and the coupling component 2 is at least formed with a through hole 201.

[0069] The first rotating component 3 is rotatably connected to the coupling component 2.

[0070] Wherein, the first rotating component 3 can rotate when the adjacent plate frame components 1 are separated.

[0071] The second rotating component 4 is rotatably connected to the first rotating component 3.

[0072] Moreover, the central position of the filter membrane 5 of the plate frame component 1 is connected to the second rotating component 4.

[0073] 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.

[0074] 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.

[0075] In this embodiment, the plate frame component 1 is the main part of the high-efficiency filter membrane component, responsible for accommodating the filter membrane 5 and bearing the stress during the high-pressure filtration process. The plate frame component 1 includes a plurality of interconnected plate frames, and through holes 201 are 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 liquid, solid impurities are intercepted in the filtering space formed by the adjacent filter membranes 5. To ensure good filtering effect, the plate frame component 1 has high sealing performance and strength and can withstand the pressure during the filtration process.

[0076] As Figure 4 and Figure 5 shown, wherein, the plate frame component 1 further includes a displacement mechanism for urging the plurality of plate frames to approach and squeeze each other, and to move away from each other. Of course, the plate frame filter press in the prior art is relatively mature and will not be elaborated here. This embodiment only focuses on the improvement of the mechanical structure for efficiently peeling off solid impurities.

[0077] As Figure 6 and Figure 7 shown, the first rotating component 3 is connected to the coupling component 2 and is disposed at the central position of the plate frame component 1. When the adjacent plate frame components 1 are separated, the first rotating component 3 will rotate, triggering the action of the second rotating component 4. The main function of the first rotating component 3 is to trigger rotation and to urge the first movement of the second rotating component 4.

[0078] The second rotating component 4 is rotatably connected to the first rotating component 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 component 3 is activated, the second rotating component 4 exhibits a first motion, causing wrinkles to form 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. For example, the plate frame assembly 1 is provided with an embedding groove in the circumferential direction, and the groove can contain a sealing strip or a pressing strip, and the edge of the filter membrane 5 is embedded in the groove. A through hole is opened at the center position of the filter membrane 5, and the edge of this through hole is mounted on the second rotating component 4. Thus, when the second rotating component 4 performs the first motion, that is, rotates, through its fixed connection with the central through hole of the filter membrane 5, the filter membrane 5 will be subjected to torsion or stretching, causing its surface to change from a flat state to a wrinkled state. This wrinkled state helps the solid impurities attached to the surface of the filter membrane 5 to fall off. Specifically, the first motion of the second rotating component 4 causes the deflection of the edge of the through hole, resulting in the concentration of force in the central area of the filter membrane 5, gradually pushing the surface of the filter membrane 5 into a wrinkled state. This kind of wrinkle can effectively reduce the adhesion force between the solid impurities and the surface of the filter membrane 5, thus facilitating the subsequent impurity cleaning step.

[0079] In this embodiment, the filter membrane 5 adopts a fiber-reinforced elastic membrane. By embedding a high-strength fiber-reinforcing layer in the elastic matrix, the elasticity, tensile strength, and filtration efficiency of the membrane are significantly improved. For example, the filter membrane 5 can be selected as a reinforced composite PVDF membrane, whose matrix is composed of a reinforced polyvinylidene fluoride (PVDF) material and embedded with a polyester fiber (PET) grid reinforcing layer. It has excellent chemical stability and mechanical properties and is suitable for high-strength sewage filtration scenarios. Due to the elastic characteristics 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 motion, which helps the surface of the filter membrane 5 to return to a smooth state.

[0080] That is to say, the elastic acting forces of the first rotating component 3 and the filter membrane 5 cause the second rotating component 4 to cycle between the first motion and the second motion, and the surface of the filter membrane 5 will also cycle between a smooth state and a wrinkled state, which helps to reduce the adhesion force between the surface of the filter membrane 5 and the solid impurities. Specifically:

[0081] In the smooth state, the surface of the filter membrane 5 is relatively uniform and smooth. Due to the relatively strong surface tension and adhesion force on the surface of the filter membrane 5, solid impurities are likely to adhere to the surface of the filter membrane 5.

[0082] When the surface of the filter membrane 5 is converted into a wrinkled state, the morphology of the surface of the filter membrane 5 changes. This morphological change is mainly used to reduce the adhesion force between the solid impurities and the surface of the filter membrane 5, making it easier for the solid impurities to detach from the surface of the filter membrane 5. Specifically, through the formation of wrinkles, 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.

[0083] When the surface of the filter membrane 5 returns to a smooth state, the interference caused by the wrinkles disappears, but the bonding force 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 no longer adhere tightly to the surface of the filter membrane 5 as they do in the smooth state, and thus are easier to peel off.

[0084] Through this state switching, 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, and ultimately improving the self-cleaning effect and filtration efficiency of the filter membrane 5.

[0085] As Figures 1 to 3 shown, the second embodiment of the present invention provides an efficient filter membrane assembly. On the basis of the above embodiment, the coupling assembly 2 includes:

[0086] A coupling shaft 202, located at the horizontal center of the plate-frame assembly 1;

[0087] Wherein, a through hole 201 is formed in the coupling shaft 202;

[0088] A coupling cavity 203, concentrically arranged with the coupling shaft 202;

[0089] Wherein, the first rotating assembly 3 is rotationally connected to the coupling shaft 202;

[0090] Wherein, at least a part of the first rotating assembly 3 is located inside the coupling cavity 203.

[0091] In this embodiment, the coupling shaft 202 is arranged at the horizontal center of the plate-frame assembly 1 and plays a role of connection and support. 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.

[0092] A through hole 201 is formed in the coupling shaft 202, which is mainly used for the entry of filtrate. The through hole 201 itself is not the main structural part of the present invention, but is a necessary channel during the liquid filtration process to allow the liquid to enter and perform the filtration operation.

[0093] The coupling cavity 203 is concentrically arranged with the coupling shaft 202 and houses a part of the first rotating assembly 3. Through the coupling cavity 203, the rotation path of the first rotating assembly 3 is ensured to be clear, and it helps to reduce external interference, improving the smoothness and reliability of rotation. The coupling cavity 203 provides a stable rotation space for the first rotating assembly 3, enabling it to smoothly drive the second rotating assembly 4 to perform a predetermined motion.

[0094] The first rotating assembly 3 is rotationally connected to the coupling shaft 202, ensuring that the rotation of the first rotating assembly 3 can effectively trigger and adjust the motion mode of the second rotating assembly 4, thereby realizing the switching of the surface state of the filter membrane 5 (mutual conversion between smooth and wrinkled states).

[0095] In a specific embodiment, the coupling cavity 203 is an annular cavity surrounding the coupling shaft 202 in the circumferential direction.

[0096] As Figure 4 , Figure 7 and Figure 11 shown, the third embodiment of the present invention provides an efficient filter membrane assembly. On the basis of the above embodiments, the first rotating assembly 3 includes:

[0097] A first rotating part 301, sleeved on the coupling shaft 202 and forming a meshing connection with the coupling shaft 202;

[0098] A second rotating part 302, connected to the circumferential wall surface of the first rotating part 301 and located inside the coupling cavity 203;

[0099] A linkage part 303, arranged along the circumferential wall surface of the second rotating part 302, for driving the second rotating assembly 4 to perform a first motion.

[0100] In this embodiment, the first rotating part 301 is a sleeve and forms a meshing connection with the coupling shaft 202. Among them, when the adjacent plate - frame assemblies 1 are separated, due to the disappearance or weakening of the mutual force between them, the first rotating part 301 will rotate in response to this separation process, and then drive the second rotating part 302 to rotate synchronously, finally driving the second rotating assembly 4 to perform a first motion.

[0101] The second rotating part 302 drives the second rotating assembly 4 to perform a first motion, promoting the switching of the surface of the filter membrane 5 from a smooth state to a wrinkled state, 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 return to the smooth state, reducing the adhesion force of the 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 its surface during the working process, thereby improving the filtering effect and reducing the need for manual cleaning.

[0102] In a specific embodiment, the second rotating part 302 is a rotating ring and is sleeved on the first rotating part 301, that is, the circumferential wall surface of the sleeve.

[0103] As Figures 1 to 7 , Figure 10 shown, the fourth embodiment of the present invention provides an efficient filter membrane module. On the basis of the above embodiments, the first rotating assembly 3 includes:

[0104] An elastic member 304, sleeved on the coupling shaft 202 and located between the first rotating part 301 and the coupling cavity 203;

[0105] Wherein, the elastic member 304 is configured to apply an axial force away from the coupling cavity 203 to the first rotating part 301.

[0106] In this embodiment, the elastic member 304 is, for example, a compression spring. By applying an axial force, it always maintains elastic support for the first rotating part 301. This force enables the first rotating part 301 to move in the axial direction away from the coupling cavity 203.

[0107] Since the first rotating part 301 and the coupling shaft 202 are meshed, when adjacent plate-and-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 by the linkage part 303 to perform the first movement.

[0108] In this embodiment, a push ring 305 is further included. The elastic member 304 applies the above axial force to the first rotating part 301 through the push ring 305. The push ring 305 and the first rotating part 301 are rotatably connected and form a fixed connection with the elastic member 304. Through the rotational connection between the push ring 305 and the first rotating part 301, it ensures that the axial force of the elastic member 304 can be stably transmitted to the first rotating part 301, ensuring its smooth axial movement and rotation.

[0109] The configuration of the elastic member 304 enables the first rotating part 301 to quickly respond to the separation action of the plate-and-frame assembly 1, move axially in a timely manner and rotate synchronously, thereby driving the second rotating assembly 4 to perform the first movement, further promoting the cleaning and maintenance of the filter membrane 5.

[0110] The elastic member 304 always applies an axial force, ensuring that the movement process of the first rotating part 301 is smoother, reducing unstable factors caused by external disturbances or internal friction of the system, and improving the working reliability of the system.

[0111] As Figures 4 to 7 shown, the fifth embodiment of the present invention provides an efficient filter membrane module. On the basis of the above embodiments, the second rotating assembly 4 includes:

[0112] The third rotating part 401 is rotatably connected to the circumferential wall surface of the first rotating part 301;

[0113] The second linkage part 402 is circumferentially arranged along the end face of the second rotating part 302 facing the coupling cavity 203;

[0114] Wherein, the second linkage part 402 and the first linkage part 303 have a contact state and a separation state;

[0115] The contact state is configured such that the third rotating part 401 executes the first movement of the second rotating assembly 4 and serves as the specific execution component of this movement;

[0116] The separation state is configured such that the third rotating part 401 executes the second movement of the second rotating assembly 4 and serves as the specific execution component of this movement.

[0117] In this embodiment, the first rotating part 301 and the third rotating part 401 are linked through a rotational connection. When the adjacent plate-frame assemblies 1 are separated, the first rotating part 301 starts to rotate in response to this separation action, and then drives the first linkage part 303 and the second linkage part 402 into the contact state. In this state, the third rotating part 401 executes the first movement.

[0118] Specifically, when the first rotating part 301 rotates, through the transmission action of the first linkage part 303, it causes the second linkage part 402 to contact the first linkage part 303, so that the third rotating part 401 enters the first movement state. At this time, the surface of the filter membrane 5 wrinkles, reducing the adhesion force between the solid impurities and the membrane surface, which is beneficial to the peeling and cleaning of the solid impurities.

[0119] When the third rotating part 401 executes the first movement, wrinkles are generated on the surface of the filter membrane 5, effectively reducing the adhesion force between the solid impurities and the membrane surface, thereby improving the self-cleaning ability of the membrane and reducing impurity residue. This process automatically starts the movement process when the plate-frame assemblies 1 are separated, realizing the automatic cleaning of the surface of the filter membrane 5, reducing manual intervention, and improving the working efficiency and the stability of the filtering equipment.

[0120] On the other hand, when the first linkage part 303 rotates away from the second linkage part 402, that is, enters the separation state, at this time, the third rotating part 401 is no longer driven by the first linkage part 303, but is controlled by the elastic force of the filter membrane 5 (that is, the force for the surface of the filter membrane 5 to return to the smooth state). In this case, the third rotating part 401 executes the second movement, that is, the surface of the filter membrane 5 returns from the wrinkled state to the smooth state.

[0121] Specifically, in the separated state, the elastic property of the filter membrane 5 comes into play, 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 push the surface of the filter membrane 5 to be smoothed, further reducing the adhesion force between the solid impurities and the membrane surface, and keeping the surface of the filter membrane 5 clean.

[0122] Through the switching between this 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 the long-term stability of the equipment.

[0123] Generally speaking, it helps the filter membrane 5 to maintain high-efficiency performance during the filtration process, effectively avoid the accumulation of impurities, increase the service life of the membrane, and reduce the maintenance cost.

[0124] As Figures 8 to 10 shown, the sixth embodiment of the present invention provides an efficient filter membrane assembly, and on the basis of the above embodiment, a plurality of arc-shaped grooves 2031 are formed along the circumferential direction of the coupling cavity 203;

[0125] Among them, the linkage two-part 402 passes through the arc-shaped groove 2031 and is in contact with the linkage one-part 303.

[0126] In this embodiment, the arc-shaped grooves 2031 are evenly distributed in the circumferential direction of the coupling cavity 203 and are used to guide the movement path of the linkage two-part 402. When the linkage two-part 402 is pushed by the linkage one-part 303 to the edge of a certain arc-shaped groove 2031, the linkage two-part 402 will be blocked, that is, the further sliding of the linkage two-part 402 along the arc-shaped groove 2031 is prevented. This blocking effect helps to promote the separation of the linkage one-part 303 and the linkage two-part 402, thereby controlling the movement of the third rotating part 401.

[0127] When the linkage two-part 402 is pulled back to the other edge of the arc-shaped groove 2031 due to the elastic force of the filter membrane 5, the linkage two-part 402 will be blocked again. At this time, the edge of the arc-shaped groove 2031 provides a stable support position and provides an initial position for the next contact between the linkage two-part 402 and the linkage one-part 303. In this way, the surface of the filter membrane 5 can be smoothly switched between the smooth state and the wrinkled state.

[0128] The arc-shaped grooves 2031 ensure the stable contact and separation state between the linkage two-part 402 and the linkage one-part 303 during the movement, making the movement process more precise and controllable. The arc-shaped grooves 2031 can not only guide the precise position of the linkage two-part 402, but also effectively utilize the elastic force of the filter membrane 5, making the state switching of the filter membrane 5 smoother, 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.

[0129] 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;

[0130] The length direction of the spring piece is perpendicular to the length direction of the rod.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] like Figure 1 andFigure 2 As shown in Figure 2 , the eighth embodiment of the present invention provides an efficient filter membrane module. On the basis of the above embodiments, the second rotating assembly 4 includes:

[0138] Two mounting rings 403 sleeved on the circumferential wall surface of the first rotating part 301;

[0139] Wherein, the third rotating part 401 is rotatably connected between the two mounting rings 403.

[0140] In this embodiment, the two mounting rings 403 play a constraining role, ensuring that the third rotating part 401 can stably rotate and sleeve on the circumferential wall surface of the first rotating part 301, and preventing the third rotating part 401 from axially moving. It can effectively prevent unnecessary displacement of the third rotating part 401 during rotation, maintaining the accuracy and stability of its movement. At the same time, the configuration of the mounting ring 403 enables the third rotating part 401 to always be on the correct track during rotation, avoiding potential problems caused by unstable movement.

[0141] As Figure 11 shown in Figure 11 , the ninth embodiment of the present invention provides an efficient filter membrane module. On the basis of the above embodiments, it also has a vibration generating structure 6;

[0142] Wherein, the vibration generating structure 6 is configured to allow the elastic piece to vibrate in the separated state and continue until the contact state.

[0143] In this embodiment, the vibration generating structure 6 of the elastic piece is configured to allow the elastic piece to generate continuous vibration when it is in the separated state. Specifically, the vibration generating structure 6 includes:

[0144] A groove provided on the end face of the elastic piece facing the rod;

[0145] And, there are several grooves arranged along the length direction perpendicular to the elastic piece.

[0146] When the elastic piece returns from the compressed state (contact state) to the free state (separated state), the elastic potential energy generated in its material will be released, which will trigger the free vibration of the elastic piece. And, the structure of introducing grooves into the elastic piece changes the local stress distribution of the elastic piece, making it produce asymmetric deformation when releasing the elastic potential energy, thus triggering periodic vibration. In addition, the other end of the elastic piece is fixed through a flexible support point, making it form a structure similar to a cantilever beam in the separated state. The flexible support point can absorb part of the vibration energy and prevent the vibration from rapidly decaying. The elastic piece is made of a material with a high elastic modulus (such as a stainless steel spring piece or a composite elastic material) to ensure that it can continuously maintain its vibration performance during repeated deformation.

[0147] These vibrations will persist until the shrapnel re - contacts the rod (i.e., the linkage part 402). When the shrapnel re - contacts the rod, the vibrations are transmitted to the rod and further to the filter membrane 5. Specifically, when the vibrating end of the shrapnel contacts the rod, the kinetic energy at 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 at 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 - lived high - frequency impacts will be formed at the moment of contact. This kind of impact can be partially absorbed by the rod and further transmitted to the filter membrane. The rod needs to be made of a material with a high elastic modulus and high kinetic energy transfer efficiency, such as high - strength aluminum alloy. This material can minimize the energy absorption during contact, thus enhancing the vibration transmission effect.

[0148] In this way, the effect of vibration transmission can enhance the peeling effect of solid impurities on the surface of the filter membrane 5, reduce the adhesion force between the solid impurities and the surface of the filter membrane 5, thereby improving the cleaning efficiency of the filter membrane 5.

[0149] The technical features of the above - mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0150] The above - mentioned embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
