Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis filtering equipment, in particular to an amphiphilic composite membrane anti-pollution reverse osmosis filtering equipment. Background Art

[0002] As we all know, with the continuous growth of demand for high-quality water resources in industrial production and residents' lives, reverse osmosis filtration equipment, as a core water treatment device, has been widely used in municipal water supply, industrial wastewater treatment, seawater desalination and other fields. Amphiphilic composite membranes, with their unique hydrophilic-lipophilic balance characteristics, can effectively reduce the adhesion of pollutants to the membrane surface, becoming a key material for improving reverse osmosis filtration efficiency and anti-pollution ability.

[0003] However, existing reverse osmosis filtration equipment has many problems in actual operation. The problems of existing technologies are: on the one hand, traditional cross-flow filtration structures mostly use fixed-angle guide vanes or static spoilers, which make it difficult to dynamically adjust the water flow state according to changes in water quality and the degree of membrane fouling. When treating complex water with high turbidity and high organic content, the laminar boundary layer formed by the water flow on the membrane surface is relatively thick, causing pollutants to easily deposit and form an irreversible fouling layer, significantly reducing membrane flux and separation efficiency; On the other hand, membrane surface contaminant removal technologies have limitations. Conventional physical cleaning relies on mechanical scraping or low-pressure flushing, which is difficult to effectively remove stubborn contaminants. While chemical cleaning can provide deep cleaning, frequent use of chemicals can accelerate membrane material aging, increase operating costs, and introduce the risk of secondary contamination. Summary of the Invention

[0006] By adopting the above technical solution, a cross-flow enhancement structure is set up, and the kinetic energy of the incoming water is used to drive the trigger component to rotate. The trigger component can periodically control the rotation of the main shaft, so that the top and bottom guide vanes rotate at an angle, and drive the active bevel gear to rotate when the main shaft rotates. The active bevel gear and the driven bevel gear are meshed and connected, and the guide vanes on both sides are driven by the driven shaft to rotate synchronously, thereby converting a single water inlet flow direction into a multi-dimensional cross-flow, increasing the shear force between the water flow and the membrane surface, and periodically controlling the start and stop of the main shaft by the trigger component, so that the guide vanes can be switched steplessly between laminar flow and turbulent flow.

[0007] The present invention is further configured as follows: the left side inside the fixed ring is rotatably connected to an output shaft, and the surfaces of the output shaft and the main shaft are both sleeved with transmission wheels, and a belt is wound between the insides of the two transmission wheels.

[0008] With the above technical solution, the output shaft drives the main shaft to rotate through the belt, and the main shaft drives the active bevel gear to rotate synchronously, thereby realizing synchronous adjustment of the speed of the guide vanes on both sides.

[0009] The present invention is further configured as follows: the guide vanes are connected in an annular manner and rotated between the surface of the fixed ring and the inner wall of the support ring, and a plurality of guide grooves are opened on the surface of the guide vanes.

[0010] By adopting the above technical solution, the migration rate of pollutants is further improved through the turbulence effect of the guide groove, and the probability of their deposition on the membrane surface is reduced.

[0011] The present invention is further configured as follows: the trigger assembly includes a rotating shaft, which is rotatably connected to the inside of the guide cylinder, and the front end of the rotating shaft surface is respectively welded with a driving blade and a rotatably provided support plate in a ring shape, and the support plate is welded to the side close to the inner wall of the guide cylinder, and the surface of the rotating shaft is sleeved with a driving gear, and the bottom of the driving gear is meshed and connected with a driven gear, the interior of the driven gear is penetrated by a connecting shaft, and a cam is sleeved on the rear side of the connecting shaft surface, and a trigger member is bolted to the bottom of the inner wall of the guide cylinder, and the trigger member is used in conjunction with the cam.

[0012] By adopting the above technical solution, a trigger component is set up, and the driving blades are driven by the impact of water flow to drive the rotating shaft to rotate, and synchronously drive the driving gear to rotate. The engagement of the driving gear and the driven gear can be used to make the connecting shaft drive the cam to rotate. When the raised part of the cam contacts the trigger part, it will push it down, causing the trigger part to conduct the signal, activating the dynamic cleaning structure and the rotation of the main shaft. When the raised part of the cam is separated from the trigger part, the passage will be disconnected, thereby stopping the main shaft and the dynamic cleaning structure. By converting the kinetic energy of the water flow into an electrical signal, the linkage start of cross-flow enhancement and membrane surface cleaning is realized, the dynamic cleaning structure is synchronously activated, and a real-time response to the pollution status is achieved.

[0013] The present invention is further configured as follows: the trigger member includes a fixed shell, the fixed shell is bolted to the bottom of the inner wall of the guide cylinder, and a moving rod is slidably provided inside the fixed shell, and the top and bottom of the moving rod are respectively bolted with a push plate and a touch point, the push plate is used in conjunction with the cam, and the bottom inside the fixed shell is bolted with a connecting point, and the connecting point is used in conjunction with the touch point.

[0014] By adopting the above technical solution, a triggering member is set. When the raised part of the cam contacts the push plate, it will push it downward, and the touch point will be pushed to move by the moving rod. When the touch point contacts the connection point, an electrical signal will be triggered to realize the linkage start of cross-flow enhancement and membrane surface cleaning. When the raised part of the cam is separated from the triggering member, the touch point will be reset and disconnected from the connection point, realizing the stop of cross-flow enhancement and membrane surface cleaning. By setting the triggering member, the cross-flow enhancement and cleaning can be carried out and stopped synchronously, which can reduce the probability of pollutant deposition and improve the cleaning effect of the membrane surface.

[0015] The present invention is further configured as follows: guide rods are passed through both sides of the inside of the touch point, and the top and bottom of the guide rods are connected to the inner wall of the fixed shell, and a reset spring 1 is sleeved on the bottom of the guide rod surface, and the top and bottom of the reset spring 1 are respectively connected to the touch point and the inner wall of the fixed shell.

[0016] By adopting the above technical solution, the guide rod and the reset spring are arranged to realize automatic reset of the touch point, so that the touch point can perform the next action.

[0017] The present invention is further configured as follows: the dynamic cleaning structure includes a fixed cylinder, the front and rear sides of the fixed cylinder are bolted with an outer ring, the inner ring is provided inside the outer ring, and a fixed plate is provided in a ring shape between the inner ring and the outer ring, the front and rear sides of the interior of the fixed cylinder are slidably provided with movable end covers, the amphiphilic reverse osmosis composite membrane structure is located inside the two movable end covers, and a cleaning assembly is provided between the opposite sides of the two movable end covers, the cleaning assembly is used in conjunction with the amphiphilic reverse osmosis composite membrane structure, the inner side of the outer ring is bolted with a shell in a ring shape, and the inner side of the shell is bolted with an electromagnet, and a magnetic plate is provided on the side of the electromagnet away from the inner wall of the shell, and a push rod is provided on the side of the magnetic plate away from the electromagnet, and the side of the push rod away from the magnetic plate passes through the interior of the shell and is connected to the movable end cover.

[0018] By adopting the above technical solution and setting a dynamic cleaning structure, when the triggering member triggers the signal, the electromagnet will be periodically energized to generate a magnetic field and generate a repulsive force, so that the magnetic plate drives the push rod to move, and the movement of the push rod will push the two movable end covers to move relative to each other. When the two movable end covers move, the cleaning component will periodically contact the amphiphilic reverse osmosis composite membrane structure and press against the membrane surface, causing the amphiphilic reverse osmosis composite membrane structure to be slightly tightened, which can cause microcracks on the membrane surface, thereby loosening pollutants. At the same time, the cleaning component will vibrate to peel off the pollutants, thereby realizing dynamic cleaning of the amphiphilic reverse osmosis composite membrane structure and ensuring the filtration accuracy of the amphiphilic reverse osmosis composite membrane structure.

[0019] The present invention is further configured as follows: guide pillars are passed through both sides of the magnetic plate, and a second reset spring is sleeved on the rear side of the guide pillar surface, and the second reset spring is connected to the magnetic plate and the inner wall of the shell on one side thereof.

[0020] By adopting the above technical solution, the linear guidance of the guide column and the symmetrical setting of the reset spring 2 can limit the movement trajectory of the magnetic plate, ensuring its stable movement, and at the same time provide elastic force for the reset of the magnetic plate after the electromagnet loses power and the magnetic field.

[0021] The present invention is further configured as follows: the cleaning assembly includes an elastic support plate, and the elastic support plate is located between two movable end covers, and a plurality of arc-shaped elastic plates are distributed on the top and bottom of the elastic support plate. A fixed frame is provided on the top of the fixed plate, and the fixed frame is connected to the fixed cylinder on one side close to the inner wall thereof, a cantilever is bolted to the top of the inner wall of the fixed frame, and a plurality of dual-chip piezoelectric ceramic sheets are provided at the bottom of the cantilever, a connecting plate is slidingly provided at the bottom inside the fixed frame, and a connecting block is connected between the connecting plate and the cantilever, and the connecting plate is used in conjunction with the arc-shaped elastic plate.

[0022] By adopting the above technical solution and setting a cleaning component, when the two movable end covers move relative to each other, the elastic support plate will be squeezed, and the two arc-shaped elastic plates will be relatively deformed, and the protrusions thereof will be displaced in the opposite direction. The arc-shaped elastic plate close to the amphiphilic reverse osmosis composite membrane structure will contact it and press against the membrane surface, causing the amphiphilic reverse osmosis composite membrane structure to be slightly tightened, which can cause microcracks on the membrane surface, thereby loosening pollutants. The arc-shaped elastic plate close to the connecting plate will push the connecting plate to move and cause the free end of the cantilever to bend upward through the connecting block, generating tensile strain. When the arc-shaped elastic plate is reset, the cantilever is pulled to bend downward, generating compressive strain bending deformation. By utilizing the inverse piezoelectric effect of the dual-chip piezoelectric ceramic piece, the mechanical bending deformation is directly converted into high-frequency vibration. Therefore, the contaminants are loosened by pressing against the membrane surface through vibration, thereby achieving the effect of cleaning the membrane surface.

[0023] The present invention is further configured as follows: the front end of the cantilever is connected to the inner wall of the fixed frame to form a fixed end, and the other end is a free end.

[0024] By adopting the above technical solution, an elastic beam vibration model is formed through the structural design of the fixed end and the free end of the cantilever. When the connecting plate pushes the connecting block, the free end of the cantilever generates forced vibration. When the dual-chip piezoelectric ceramic piece bends and deforms, the vibration amplitude is amplified through the inverse piezoelectric effect, forming a high-frequency mechanical wave.

[0025] Compared with the prior art, the present invention provides an amphiphilic composite membrane anti-pollution reverse osmosis filtration device, which has the following beneficial effects: This amphiphilic composite membrane anti-pollution reverse osmosis filtration equipment achieves the anti-pollution effect of integrating inlet water flow optimization and online cleaning through the collaborative design of the cross-flow enhancement structure to dynamically control the water flow state and the dynamic cleaning structure to actively remove pollutants: the cross-flow enhancement structure optimizes the water flow field on the membrane surface in real time through fluid-driven guide blade angle adjustment and turbulence induction, reducing the probability of pollutant deposition, while the dynamic cleaning structure utilizes the high-frequency vibration of the dual-chip piezoelectric ceramic and the mechanical deformation of the arc-shaped elastic plate to form a composite cleaning mechanism of vibration cavitation and flexible scraping, which can efficiently remove pollutants from the membrane surface and effectively ensure the filtration accuracy of the membrane; and through the linkage of the trigger component and the electromagnetic drive mechanism, the cross-flow enhancement and membrane surface cleaning functions can be automatically and periodically started and stopped, achieving a dynamic balance between energy consumption and cleaning effect.

Example

[0029] See also Figure 1-5 An amphiphilic composite membrane anti-pollution reverse osmosis filtration device includes an equipment bracket 1, a mounting barrel 2 is bolted to the interior of the equipment bracket 1, a liquid inlet pipe 3 and a liquid outlet pipe 4 are connected to the front and rear sides of the mounting barrel 2, a cross-flow enhancement structure 5 and a dynamic cleaning structure 6 are respectively provided inside the mounting barrel 2, and an amphiphilic reverse osmosis composite membrane structure 7 is provided inside the dynamic cleaning structure 6; The cross-flow enhancement structure 5 includes a support ring 51, a fixed ring 52 is provided inside the support ring 51, and a guide vane 53 is rotatably provided between the fixed ring 52 and the support ring 51, the front side of the fixed ring 52 is connected to the guide cylinder 54, and a trigger assembly 55 is provided inside the guide cylinder 54, the interior of the fixed ring 52 is rotatably connected to the main shaft 56, and the surface of the main shaft 56 is sleeved with a driving bevel gear 57, both sides of the driving bevel gear 57 are meshed with a driven bevel gear 58, and a driven shaft 59 is provided inside the driven bevel gear 58, and the driven shaft 59 and the main shaft 56 are respectively connected to the guide vane 53 at one end thereof, by setting The cross-flow enhancement structure 5 utilizes the kinetic energy of the incoming water to drive the trigger component 55 to rotate. The trigger component 55 can periodically control the rotation of the main shaft 56 to cause the top and bottom guide blades 53 to rotate at an angle. When the main shaft 56 rotates, it drives the active bevel gear 57 to rotate, and through the meshing connection between the active bevel gear 57 and the driven bevel gear 58, the guide blades 53 on both sides are driven to rotate synchronously through the driven shaft 59, thereby converting the single incoming water flow direction into a multi-dimensional cross-flow, increasing the shear force between the water flow and the membrane surface, and by periodically controlling the start and stop of the main shaft 56 through the trigger component 55, the guide blades 53 can be switched steplessly between laminar flow and turbulent flow.

[0030] Among them, the left side of the fixed ring 52 is connected to the output shaft 8, and the surfaces of the output shaft 8 and the main shaft 56 are both sleeved with transmission wheels 9. A belt is wrapped between the insides of the two transmission wheels 9. The output shaft 8 drives the main shaft 56 to rotate through the belt, and the main shaft 56 drives the active bevel gear 57 to rotate synchronously, thereby realizing synchronous adjustment of the speed of the guide blades 53 on both sides.

[0031] Among them, the guide blade 53 is connected in a circular rotation between the surface of the fixed ring 52 and the inner wall of the support ring 51. A number of guide grooves are opened on the surface of the guide blade 53. The turbulence effect of the guide grooves further improves the migration rate of pollutants and reduces their deposition probability on the membrane surface.

[0032] Among them, the trigger assembly 55 includes a rotating shaft 551, which is rotatably connected to the inside of the guide cylinder 54. The front end of the surface of the rotating shaft 551 is respectively welded with a driving blade 552 in a ring shape and a support plate 553 for rotation. The support plate 553 is welded to the side close to the inner wall of the guide cylinder 54. The surface of the rotating shaft 551 is sleeved with a driving gear 554, and the bottom of the driving gear 554 is meshed with a driven gear 555. The interior of the driven gear 555 is penetrated by a connecting shaft 556, and the rear side of the surface of the connecting shaft 556 is sleeved with a cam 557. The bottom of the inner wall of the guide cylinder 54 is bolted with a trigger member 558, and the trigger member 558 is used in conjunction with the cam 557. By setting the trigger assembly 55, the drive The moving blades 552 are impacted by the water flow to drive the rotating shaft 551 to rotate, and synchronously drive the driving gear 554 to rotate. The engagement of the driving gear 554 and the driven gear 555 can be used to make the connecting shaft 556 drive the cam 557 to rotate. When the raised part of the cam 557 contacts the trigger member 558, it will push it down, causing the trigger member 558 to conduct the signal, activating the dynamic cleaning structure 6 and the rotation of the main shaft 56. When the raised part of the cam 557 is separated from the trigger member 558, the passage will be disconnected, thereby stopping the main shaft 56 and the dynamic cleaning structure 6. By converting the kinetic energy of the water flow into an electrical signal, the linkage start of cross-flow enhancement and membrane surface cleaning is realized, the dynamic cleaning structure 6 is synchronously activated, and a real-time response to the pollution status is achieved.

[0033] The trigger member 558 includes a fixed shell 558a, which is bolted to the bottom of the inner wall of the guide tube 54, and a moving rod 558b is slidably provided inside the fixed shell 558a, and the top and bottom of the moving rod 558b are bolted to a push plate 558c and a touch point 558d respectively, and the push plate 558c is used in conjunction with the cam 557, and the bottom of the fixed shell 558a is bolted to a connecting point 558e, and the connecting point 558e is used in conjunction with the touch point 558d. By setting the trigger member 558, when the protrusion of the cam 557 is in contact with the push plate 558c, the trigger member 558 is triggered. 8c contact will push it downward and push the touch point 558d to move through the moving rod 558b. When the touch point 558d contacts the connecting point 558e, an electrical signal will be triggered to realize the linkage start of cross-flow enhancement and membrane surface cleaning. When the protrusion of the cam 557 is separated from the trigger part 558, the touch point 558d will be reset and disconnected from the connecting point 558e, realizing the stop of cross-flow enhancement and membrane surface cleaning. Through the setting of the trigger part 558, the cross-flow enhancement and cleaning can be carried out and stopped synchronously, which can reduce the probability of pollutant deposition and improve the cleaning effect of the membrane surface.

[0034] Among them, guide rods 10 are passed through both sides of the inside of the touch point 558d, and the top and bottom of the guide rod 10 are connected to the inner wall of the fixed shell 558a. A reset spring 11 is sleeved on the bottom of the surface of the guide rod 10, and the top and bottom of the reset spring 11 are respectively connected to the touch point 558d and the inner wall of the fixed shell 558a. Through the setting of the guide rod 10 and the reset spring 11, the touch point 558d can be automatically reset, which facilitates the touch point 558d to perform the next action.

[0035] Working principle of this embodiment: Raw water enters the installation cylinder 2 from the liquid inlet pipe 3, and the water flow impacts the driving blade 552 to rotate the rotating shaft 551, driving the driving gear 554 to mesh with the driven gear 555, and the cam 557 on the connecting shaft 556 rotates accordingly.

Therefore, the angular rotation of the guide vanes 53 converts the single water inlet flow into a multi-directional cross flow, forming a complex flow field on the membrane surface, significantly increasing the shear force between the water flow and the membrane surface. At the same time, the guide grooves on the surface of the guide vanes 53 guide the water flow to form micro-scale vortices, which continuously cut the laminar boundary layer on the membrane surface, destroying the deposition conditions of pollutants on the membrane surface, and causing the pollutants to migrate and be discharged with the water flow. Example

[0036] refer to Figure 6 and 7, an amphiphilic composite membrane anti-pollution reverse osmosis filtration device also includes a dynamic cleaning structure 6, wherein the dynamic cleaning structure 6 includes a fixed cylinder 61, the front and rear sides of the fixed cylinder 61 are bolted with an outer ring 62, an inner ring 63 is provided inside the outer ring 62, and a fixed plate 64 is provided in an annular shape between the inner ring 63 and the outer ring 62, and a movable end cover 65 is slidably provided on the front and rear sides of the interior of the fixed cylinder 61, the amphiphilic reverse osmosis composite membrane structure 7 is located inside the two movable end covers 65, and a cleaning component 66 is provided between the opposite sides of the two movable end covers 65, and the cleaning component 66 is used in conjunction with the amphiphilic reverse osmosis composite membrane structure 7, the inner side of the outer ring 62 is bolted with a shell 67 in an annular shape, and the inner side of the shell 67 is bolted with an electromagnet 68, and a magnetic plate 69 is provided on the side of the electromagnet 68 away from the inner wall of the shell 67, and the magnetic plate 69 is away from the electromagnet 68 A push rod 610 is provided on one side, and the side of the push rod 610 away from the magnetic plate 69 passes through the interior of the shell 67 and is connected to the movable end cover 65. By setting the dynamic cleaning structure 6, when the trigger member 558 triggers the signal, the electromagnet 68 will be energized periodically to generate a magnetic field and generate a repulsive force, so that the magnetic plate 69 drives the push rod 610 to move. The movement of the push rod 610 will push the two movable end covers 65 to move relative to each other. When the two movable end covers 65 move, the cleaning component 66 will periodically contact the amphiphilic reverse osmosis composite membrane structure 7 and press against the membrane surface, causing the amphiphilic reverse osmosis composite membrane structure 7 to produce a slight tension, which can cause microcracks on the membrane surface, thereby loosening pollutants. At the same time, the cleaning component 66 will vibrate to peel off the pollutants, thereby realizing dynamic cleaning of the amphiphilic reverse osmosis composite membrane structure 7 and ensuring the filtration accuracy of the amphiphilic reverse osmosis composite membrane structure 7. Among them, guide pillars 12 are passed through both sides of the inside of the magnetic plate 69, and a reset spring 2 13 is sleeved on the rear side of the surface of the guide pillar 12. The reset spring 2 13 is connected to the magnetic plate 69 and the inner wall of the shell 67 on one side respectively. The linear guidance of the guide pillar 12 and the symmetrical setting of the reset spring 2 13 can limit the moving trajectory of the magnetic plate 69, ensuring its stable movement. At the same time, it provides elastic force for the reset of the magnetic plate 69 after the electromagnet 68 loses power and loses the magnetic field.

[0037] Among them, the cleaning component 66 includes an elastic support plate 661, and the elastic support plate 661 is located between the two movable end covers 65. Several arc-shaped elastic plates 662 are distributed on the top and bottom of the elastic support plate 661. A fixed frame 663 is provided on the top of the fixed plate 64. The fixed frame 663 is connected to the side of the inner wall of the fixed cylinder 61. A cantilever 664 is bolted to the top of the inner wall of the fixed frame 663, and several dual-chip piezoelectric ceramic pieces 665 are provided at the bottom of the cantilever 664. A connecting plate 666 is slidingly provided at the bottom inside the fixed frame 663, and a connecting block 667 is connected between the connecting plate 666 and the cantilever 664. The connecting plate 666 is used in conjunction with the arc-shaped elastic plate 662. By setting the cleaning component 66, the elastic support plate 66 will be squeezed when the two movable end covers 65 move relative to each other. 1, and make the two arc-shaped elastic plates 662 produce relative deformation, and make their protrusions move in opposite directions. The arc-shaped elastic plate 662 close to the amphiphilic reverse osmosis composite membrane structure 7 contacts it and presses against the membrane surface, causing the amphiphilic reverse osmosis composite membrane structure 7 to produce a slight tension, which can cause microcracks on the membrane surface, thereby loosening pollutants, and the arc-shaped elastic plate 662 close to the connecting plate 666 will push the connecting plate 666 to move and make the free end of the cantilever 664 warp upward through the connecting block 667, generating tensile strain, and when the arc-shaped elastic plate 662 is reset, it pulls the cantilever 664 to bend downward, generating compressive strain bending deformation, thereby utilizing the inverse piezoelectric effect of the dual-chip piezoelectric ceramic piece 665, and the mechanical bending deformation is directly converted into high-frequency vibration. Therefore, the vibration is combined with the pressing of the membrane surface to loosen pollutants, thereby achieving the effect of cleaning the membrane surface.

[0038] Among them, the front end of the cantilever 664 is connected to the inner wall of the fixed frame 663 to form a fixed end, and the other end is a free end. The structural design of the fixed end and the free end of the cantilever 664 forms an elastic beam vibration model. When the connecting plate 666 pushes the connecting block 667, the free end of the cantilever 664 generates forced vibration; when the dual-chip piezoelectric ceramic piece 665 bends and deforms, the vibration amplitude is amplified through the inverse piezoelectric effect to form a high-frequency mechanical wave.

[0039] Working principle of this embodiment: After the trigger assembly 55 conducts the signal, the electromagnet 68 is periodically energized to generate a magnetic field, which repels the magnetic plate 69 and drives the push rod 610 to move. The push rod 610 pushes the two movable end covers 65 to move relative to each other and compresses the reset spring 13. The extrusion of the movable end cover 65 causes the elastic support plate 661 to deform, and the raised portion of the arc-shaped elastic plate 662 presses against the membrane surface, causing the membrane to produce a slight radial tension. This tensioning state produces microscopic stress concentration on the membrane surface, causing microcracks to form at the junction of the contaminant and the membrane surface, weakening the adhesion of the contaminant; at the same time, the arc-shaped elastic plate 662 near the side of the connecting plate 666 pushes the connecting plate 666 to move , the free end of the cantilever 664 generates bending vibration through the connecting block 667, and the dual-chip piezoelectric ceramic piece 665 is bent and deformed under the drive of the cantilever 664, and the inverse piezoelectric effect is used to convert the mechanical deformation into high-frequency vibration. The ultrasonic cavitation effect generated by the vibration forms tiny bubbles on the surface of the membrane. The energy released when the bubbles burst further peels off the loose pollutants; after the electromagnet 68 is powered off, the reset spring 13 pushes the magnetic plate 69 to reset, the movable end cover 65 automatically resets, and the arc-shaped elastic plate 662 and the connecting plate 666 return to their initial state, waiting for the next trigger signal. This process is repeated periodically to achieve continuous dynamic cleaning of the membrane surface.
