Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a high-efficiency sewage treatment dual-pressure ceramic membrane filtration device. Background Art

[0002] The dual-pressure ceramic membrane filtration device for sewage treatment is an innovative sewage treatment equipment that integrates a nano-ceramic membrane biofilter tower and a dual-ceramic membrane filter. It uses two sets of inorganic ceramic membrane filters (one for use and one for backup) to operate in parallel, and realizes solid-liquid separation through cross-flow filtration. When the pressure of the main filter is abnormal, the system automatically switches to the backup filter to avoid shutdown for maintenance and ensure continuous operation.

[0003] In the prior art, when a sewage treatment double-pressure ceramic membrane filter device treats sewage, the sewage is sent into a double-ceramic membrane filter for filtration through a pump body. Since the sewage contains a large amount of pollutants and floating objects, when the double-ceramic membrane filter is filtering, the pollutants and floating objects will not only accumulate or adhere to the double-ceramic membrane filter, increasing the difficulty and time of cleaning, resulting in a decrease in sewage treatment efficiency, but the accumulated pollutants and floating objects will easily hinder the flow of water, further reducing the sewage treatment efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that when a dual-pressure ceramic membrane filter device for sewage treatment treats sewage, the sewage is sent into the dual-ceramic membrane filter for filtration through a pump body.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Example 1:

[0034] See also Figures 1-8As shown, a high-efficiency sewage treatment dual-pressure ceramic membrane filtration device comprises a base 1; a sewage tank 2, a nano-ceramic membrane biofilter body 3 and a clean water tank 4 are provided on the top of the outer wall of the base 1; a delivery pump 5, a sewage pump 6 and a clean water pump 7 are fixedly connected to the top of the outer wall of the base 1; the input end and the output end of the delivery pump 5 are connected to the sewage tank 2 and the nano-ceramic membrane biofilter body 3 through pipe 1 and pipe 2 respectively; the input end of the sewage pump 6 is connected to the nano-ceramic membrane biofilter body 3 through pipe 3; the output end of the sewage pump 6 is provided with a ceramic membrane filter assembly body 8 through a delivery pipe; the input end of the clean water pump 7 is connected to the ceramic membrane filter assembly body 8, and the output end of the clean water pump 7 is connected to the clean water tank 4 through pipe 5; a motor 9 is fixedly connected to one side of the outer wall of the sewage tank 2 through a fixed block; a reciprocating shaft 10 is provided at the output end of the motor 9; a reciprocating plate 11 is provided on the outer wall of the reciprocating shaft 10; The guide plate 12 is provided, and the top end of the inner wall of the guide plate 12 contacts the top end of the outer wall of the reciprocating plate 11; a pair of auxiliary rods 13 are slidably connected to one side of the outer wall of the reciprocating plate 11; the bottom end of the outer wall of the pair of auxiliary rods 13 is fixedly connected to a collecting shell 14, and the collecting shell 14 has buoyancy. By discharging sewage into the sewage tank 2, the motor 9 drives the reciprocating shaft 10 to rotate, so that the reciprocating shaft 10 drives the reciprocating plate 11 to reciprocate, so that the reciprocating plate 11 drives the pair of auxiliary rods 13 to move, and the auxiliary rods 13 drive the collecting shell 14 to move. Due to the buoyancy of the collecting shell 14 and the weight of the collecting shell 14, a small part of the bottom of the collecting shell 14 is located in the water, so that the collecting shell 14 collects pollutants and floating objects when it moves, reducing the content of pollutants and floating objects in the subsequent sewage, thereby reducing the number of pollutants and floating objects adhering to or accumulating in the double ceramic membrane filter, thereby reducing the cleaning difficulty and time, and improving the sewage treatment efficiency.

[0035] An auxiliary plate 15 is fixedly connected to one side of the outer wall of the collection shell 14; a placement plate 16 is fixedly connected to the bottom end of one side of the outer wall of the collection shell 14, and the placement plate 16 has buoyancy; a roller 151 and a roller 2 152 are rotatably connected to one side of the outer wall of the auxiliary plate 15; the roller 151 and the roller 2 152 are connected by a conveyor belt 153; a rotating rod 154 and a rotating rod 2 155 are fixedly connected to one end of the outer wall of the roller 151 and the roller 2 152 respectively; the outer wall of the rotating rod 154 is fixedly connected to the gear 1 56; The inner wall of the sewage tank 2 is slidably connected to a rack 157, and one side of the outer wall of the collection shell 14 is slidably connected to one side of the outer wall of the rack 157; a feeding mechanism is provided on one side of the outer wall of the auxiliary plate 15; a collection box 17 is fixedly connected to the top of the outer wall of the placement plate 16, and the collection box 17 matches the feeding mechanism; a gear 156 and a rack 157 are meshed with each other, and when pollutants and floating objects enter the collection shell 14, the pollutants and floating objects encounter the conveyor belt as the collection shell 14 moves. 153, when the collection shell 14 moves, it drives the auxiliary plate 15 and the placement plate 16 to move. The auxiliary plate 15 drives the roller 151, the roller 2 152, the rotating rod 154 and the gear 156 of the rotating rod 154 to move. Because the gear 156 and the rack 157 are meshed with each other, when the gear 156 moves, it rotates through the rack 157. The rack 157 can only move up and down in the sewage shell, and the collection shell 14 drives the rack 157 to move up and down, so that when the sewage rises or falls, the gear Bar 157 is always meshed with gear 156. The rotation of gear 156 drives rotating rod 154 and roller 151 to rotate, thereby driving conveyor belt 153 and roller 2 152 to rotate, so that pollutants and floating objects are transported to the top of conveyor belt 153 when they encounter conveyor belt 153, and then fall into collection box 17, so that the device can collect more pollutants and floating objects, and can be used for a long time without processing pollutants and floating objects, thereby reducing the workload of staff.

[0036] One side of the inner wall of the collecting shell 14 is rotatably connected to the crushing roller three 141 and the crushing roller four 142; one end of the outer wall of the crushing roller three 141 and the crushing roller four 142 is fixedly connected to the rotating rod three 143 and the rotating rod four 144 respectively, and one end of the outer wall of the rotating rod three 143 and the rotating rod four 144 extends out of the collecting shell 14; the outer side wall of the rotating rod three 143 and the rotating rod four 144 located outside the collecting shell 14 is fixedly connected to the gear two 145, and the pair of gears two 145 are meshed with each other; the outer side wall of the rotating rod two 155 and the rotating rod three 143 is fixedly connected to the sprocket one 146, and the pair of sprockets one 146 are connected by the chain one 147. When the rotating roller two 152 rotates, the rotating roller two 152 drives the rotating rod two 155 to rotate. Because the outer side walls of the rotating rod two 155 and the rotating rod three 143 are fixedly connected, the rotating roller two 152 drives the rotating rod two 155 to rotate. A sprocket 146 is fixedly connected, and a pair of sprockets 146 are connected by a chain 147, so that the rotating rod 2 155 drives the rotating rod 3 143 to rotate through the sprocket 146 and the chain 1 147. Since the outer side walls of the rotating rod 3 143 and the rotating rod 4 144 at one end outside the collecting shell 14 are fixedly connected with the gear 2 145, and the pair of gears 2 145 are engaged with each other, the rotating rod 3 143 drives the rotating rod 4 144 to rotate through the pair of gears 2 145, thereby driving the crushing roller 3 141 and the crushing roller 4 142 to rotate, so that the rotation of the crushing roller 3 141 and the crushing roller 4 142 crushes larger pollutants and floating objects, thereby facilitating the collection and storage of pollutants and floating objects, as well as improving the efficiency of pollutant and floating object treatment, reducing equipment loss and optimizing resource utilization.

[0037] The inner wall of the collection box 17 is slidably connected to a lifting plate 173; a group of water holes 174 are opened on the lifting plate 173, the collection shell 14 and the placement plate 16, and the three groups of water holes 174 correspond to each other; a pulling plate 175 is fixed to the top of the outer wall of the lifting plate 173. When the pollutants and floating objects in the collection box 17 are almost collected, the pulling plate 175 is pulled to make the lifting plate 173 rise, and the lifting plate 173 drives the pollutants and floating objects to rise, thereby making it easier for the staff to take away the pollutants and floating objects, and also speeding up the efficiency of taking or collecting the pollutants and floating objects.

[0038] The feeding mechanism includes a square shell 171; one side of the outer wall of the square shell 171 is fixedly connected to one side of the outer wall of the auxiliary plate 15 through a connecting block; one side of the inner wall of the square shell 171 is fixedly connected to a scraper 172 through a group of springs, and the outer side wall of the scraper 172 is slidably connected to the inner side wall of the square shell 171; the scraper 172 matches the conveyor belt 153; the square shell 171 matches the collecting box 17; the top of the outer wall of the square shell 171 is provided with an inclined surface, and the inclined surface matches the scraper 172. When the pollutants and floating objects are transported to the top of the conveyor belt 153, the pollutants and floating objects encounter the scraper 172. At this time, the scraper 172 scrapes off the pollutants and floating objects on the conveyor belt 153, making it difficult for the pollutants and floating objects to adhere to the conveyor belt 153, so that the conveyor belt 153 can operate normally and transport pollutants and floating objects, and also make the collection of pollutants and floating objects more stable.

[0039] A rotating rod 148 is fixedly connected to one side of the outer wall of the collection shell 14, and one end of the outer wall of the rotating rod 148 extends outside the collection shell 14; a group of rotating plates 149 are fixedly connected to the outer wall of the end of the rotating rod 148 located inside the collection shell 14; the outer wall of the end of the rotating rod 148 located outside the collection shell 14 and the outer wall of the rotating rod 4 144 are fixedly connected to a sprocket 2 491, and a pair of sprockets 2 491 are connected by a chain 2 492, through the outer wall of the end of the rotating rod 148 located outside the collection shell 14 and the outer side of the rotating rod 4 144 The walls are fixedly connected with a sprocket 2 491, and a pair of sprockets 2 491 are connected by a chain 2 492, so that the rotation of the rotating rod 4 144 drives the rotating rod 148 to rotate, and the rotating rod 148 drives a group of rotating plates 149 to rotate. When the rotating plates 149 rotate, local vortexes or directional water flows are formed, so that pollutants and floating objects are entrained by the water flow and move with the rotating plates 149 to the inside of the inlet of the collection shell 14, so that pollutants and floating objects are more convenient to be collected, and pollutants and floating objects can be cleaned more thoroughly.

[0040] A sealing shell 30 is fixedly connected to one side of the outer wall of the collecting shell 14; the sealing shell 30 is sealed and rotatably connected to the rotating rod 2 155, the rotating rod 3 143, the rotating rod 4 144 and the rotating rod 148; the chain 1 147, the chain 2 492 and the pair of gears 2 145 are all located in the sealing shell 30. Since the chain 147, the chain 2 492 and the pair of gears 2 145 are located in the sealing shell 30, and the gear 1 156 and the rack 1 157 are located at a high position, it is not easy for sewage and pollutants and floating objects in the sewage to adhere, so that the pollutants, floating objects and sewage are not easy to corrode the transmission mechanism in the device, thereby making the device more stable. At the same time, it also increases the life of the transmission mechanism in the device and reduces the probability of failure of the transmission mechanism in the device.

[0041] The bottom end of the inner wall of the collection shell 14 is fixed with an arc guide plate 18, and the arc guide plate 18 matches the rotating plate 149 and the crushing roller; the outer wall of the conveyor belt 153 is fixed with a group of auxiliary strips 19, and the group of auxiliary strips 19 matches the crushing roller and the scraper 172; the bottom end of the outer wall of the auxiliary strip 19 is triangular in shape. When the rotating plate 149 rotates, driving the pollutants and floating objects into the collection shell 14, one end of the rotating plate 149 will contact the arc plate of the arc guide plate 18, driving the pollutants and floating objects to one end, so that the pollutants and floating objects move to the arc guide plate. The top of the guide plate 18 moves along the inclined surface of the top to between the crushing roller three 141 and the crushing roller four 142, so that the crushing roller three 141 and the crushing roller four 142 can more conveniently crush the pollutants and floating objects. A group of auxiliary strips 19 are fixedly connected to the outer wall of the conveyor belt 153, so that the pollutants and floating objects contact the conveyor belt 153 and are transported by the conveyor belt 153. The auxiliary strips 19 will block the pollutants and floating objects, making it more difficult for the pollutants and floating objects to slide, thereby making the collection operation of pollutants and floating objects more convenient and stable.

[0042] Example 2:

[0043] See also Figure 1 and Figures 9-11 As shown, the top of the outer wall of the base 1 is fixed with a reciprocating rod 20 through a square plate; the outer wall of the reciprocating rod 20 is provided with a reciprocating block 21; the inner side walls on both sides of the reciprocating block 21 are fixed with cleaning rings 22; a pair of cleaning rings 22 are respectively matched with a pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8; the outer side walls of the reciprocating rod 20 and the reciprocating shaft 10 are fixed with sprocket three 23, and the pair of sprocket three 23 are connected by chain three 24, so that the reciprocating shaft 10 can be reciprocated. The rotation drives the reciprocating rod 20 to rotate through the sprocket three 23 and the chain three 24, so that the reciprocating rod 20 drives the reciprocating block 21 to move, and the reciprocating block 21 drives the pair of cleaning rings 22 to move. Because the pair of cleaning rings 22 are blocked by the pair of inorganic ceramic membrane filters, the pair of cleaning rings 22 and the reciprocating block 21 can only move but cannot rotate, so that the movement of the pair of cleaning rings 22 cleans the outer surfaces of the pair of inorganic ceramic membrane filters, thereby solving the problem of chemical residues on the inorganic ceramic membrane filters, and also solving the problem of outer surface corrosion of the inorganic ceramic membrane filters, so that the service life of the ceramic membrane filter assembly body 8 is increased.

[0044] One side of the outer wall of the reciprocating block 21 is slidably connected to a gear 5 211 through a group of round rods 1, and the inner side wall of the gear 5 211 is slidably connected to the outer side wall of the reciprocating rod 20; one side of the outer wall of a pair of cleaning rings 22 is rotatably connected to a group of round rods 212, and the two groups of round rods 212 respectively penetrate the pair of cleaning rings 22; one end of the outer wall of the two groups of round rods 212 that does not penetrate the cleaning ring 22 is fixedly connected to a gear 8 213; the outer side wall of one end of the two groups of round rods 212 that penetrates the cleaning ring 22 is fixedly connected to a group of vibrating rods 214; One end of the outer wall of each group of vibration rods 214 is fixed with a vibration ball 215, and multiple groups of vibration balls 215 are respectively matched with a pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8; one side of the outer wall of the reciprocating block 21 is slidably connected with a pair of annular racks 216 through a pair of connecting plates, and the pair of annular racks 216 are respectively matched with two groups of gears 8 213; the gear 5 211 and the pair of annular racks 216 are meshed with each other, and when the reciprocating block 21 and the cleaning ring 22 move, the reciprocating block 21 drives the gear 5 2 11 moves, and the rotation of the reciprocating rod 20 drives the gear five 211 to rotate, so that the gear five 211 rotates and moves. The rotation of the gear five 211 drives the pair of annular racks 216 to rotate. The rotation of the pair of annular racks 216 drives the two sets of gear eight 213 to rotate, thereby driving the two sets of circular rods 212 to rotate, so that the two sets of circular rods 212 drive multiple sets of vibration rods 214 and vibration balls 215 to rotate, so that the vibration balls 215 knock on the outer surfaces of the pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8, generating vibration. Because the vibration balls 215 move and rotate and knock, the outer surfaces of the pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8 can be uniformly subjected to vibration force. When the pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8 are vibrated, the vibration loosens the contaminants on the membrane surface through mechanical energy transmission. Combined with flushing or backflushing operations, the pollutant discharge efficiency can be significantly improved. The ceramic membrane assembly often adopts cross-flow filtration. The fluid flows tangentially through the membrane surface at high speed, forming a shear force to flush the contaminants. Vibration can further enhance this shear effect, making it easier for hard scale (such as inorganic salt crystals) or soft scale (such as organic matter) deposited on the membrane surface to fall off, reducing concentration polarization. When dust or particles accumulate on the membrane surface to form a filter cake layer, vibration can destroy the integrity of the filter cake structure, breaking it into small pieces and falling off, thereby reducing pollutant accumulation, extending membrane life, reducing energy consumption and operating costs, and improving treatment stability and safety.

[0045] When the present invention is in use, sewage is discharged into the sewage tank 2. At this time, the motor 9 drives the reciprocating shaft 10 to rotate, so that the reciprocating shaft 10 drives the reciprocating plate 11 to reciprocate, so that the reciprocating plate 11 drives a pair of auxiliary rods 13 to move, and the auxiliary rods 13 drive the collecting shell 14 to move. Due to the buoyancy of the collecting shell 14 and the influence of the weight of the collecting shell 14, a small part of the bottom of the collecting shell 14 is located in the water, so that the collecting shell 14 collects pollutants and floating objects when it moves, reducing the content of pollutants and floating objects in the subsequent sewage, thereby reducing the number of pollutants and floating objects adhering to or accumulating in the double ceramic membrane filter, thereby reducing the cleaning difficulty and time, and improving the sewage treatment efficiency.

[0046] When pollutants and floating objects enter the collection shell 14, the pollutants and floating objects encounter the conveyor belt 153 as the collection shell 14 moves. When the collection shell 14 moves, it drives the auxiliary plate 15 and the placement plate 16 to move. The auxiliary plate 15 drives the roller 151, the roller 2 152, the rotating rod 154 and the gear 156 of the rotating rod 154 to move. Because the gear 156 and the rack 157 are meshed with each other, the gear 156 rotates through the rack 157 when it moves. The rack 157 can only move up and down in the sewage shell, and the collection shell 14 drives the rack When rack 157 moves up and down to make the sewage rise or fall, rack 157 is always engaged with gear 156. The rotation of gear 156 drives rotating rod 154 and roller 151 to rotate, thereby driving conveyor belt 153 and roller 2 152 to rotate, so that pollutants and floating objects are transported to the top of conveyor belt 153 when they encounter conveyor belt 153, and then fall into collection box 17, so that the device can collect more pollutants and floating objects, and can be used for a long time without processing pollutants and floating objects, thereby reducing the workload of staff.

[0047] When the pollutants and floating objects are transported to the top of the conveyor belt 153, the pollutants and floating objects encounter the scraper 172. At this time, the scraper 172 scrapes off the pollutants and floating objects on the conveyor belt 153, making it difficult for the pollutants and floating objects to adhere to the conveyor belt 153, so that the conveyor belt 153 can operate normally and transport pollutants and floating objects, and also make the collection of pollutants and floating objects more stable.

[0048] When the second roller 152 rotates, the second roller 152 drives the second rotating rod 155 to rotate. Since the outer walls of the second rotating rod 155 and the third rotating rod 143 are fixedly connected with the sprocket 146, and the pair of sprockets 146 are connected by the chain 147, the second rotating rod 155 drives the third rotating rod 143 to rotate through the sprocket 146 and the chain 147. Since the outer walls of the third rotating rod 143 and the fourth rotating rod 144 at one end outside the collecting shell 14 are fixedly connected with the gear 2 145, and the pair of gears 2 145 are meshed with each other, the third rotating rod 143 drives the fourth rotating rod 144 to rotate through the pair of gears 2 145, thereby driving the crushing roller 3 141 and the crushing roller 4 142 to rotate, so that the rotation of the crushing roller 3 141 and the crushing roller 4 142 crushes larger pollutants and floating objects, thereby facilitating the collection and storage of pollutants and floating objects, as well as improving the efficiency of pollutant and floating object treatment, reducing equipment loss and optimizing resource utilization.

[0049] Sprocket 2 491 is fixedly connected to the outer wall of one end of the rotating rod 148 located outside the collecting shell 14 and the outer wall of the rotating rod 4 144, and a pair of sprockets 2 491 are connected by chain 2 492, so that the rotation of the rotating rod 4 144 drives the rotating rod 148 to rotate, and the rotating rod 148 drives a group of rotating plates 149 to rotate. When the rotating plates 149 rotate, local vortexes or directional water flows are formed, so that pollutants and floating objects are entrained by the water flow and move with the rotating plates 149 to the inside of the inlet of the collecting shell 14, so that pollutants and floating objects are more convenient to be collected and can be cleaned more thoroughly.

[0050] When the rotating plate 149 rotates, driving the pollutants and floating objects into the collection shell 14, one end of the rotating plate 149 will contact the arc plate of the arc guide plate 18, driving one end of the pollutants and floating objects, so that the pollutants and floating objects move to the top of the arc guide plate 18, and then move along the inclined surface of the top to between the crushing roller three 141 and the crushing roller four 142, so that the crushing roller three 141 and the crushing roller four 142 can more conveniently crush the pollutants and floating objects. A group of auxiliary strips 19 are fixedly connected to the outer wall of the conveyor belt 153, so that when the pollutants and floating objects contact the conveyor belt 153 and are transported by the conveyor belt 153, the auxiliary strips 19 will block the pollutants and floating objects, making it more difficult for the pollutants and floating objects to slide, thereby making the collection operation of pollutants and floating objects more convenient and stable.

[0051] When the water pollutants and floating objects in the sewage in the sewage tank 2 are almost cleaned, the sewage is sent to the nano-ceramic membrane biofilter tower body 3 for treatment through the delivery pump 5, and then the treated sewage is sent to the ceramic membrane filter assembly body 8 for treatment through the sewage pump 6. The clean water after further treatment is sent to the clean water tank 4 for collection through the clean water pump 7.

[0052] When the pollutants and floating objects in the collection box 17 are almost collected, the pulling plate 175 is pulled to drive the lifting plate 173 to rise, and the lifting plate 173 drives the pollutants and floating objects to rise, thereby making it easier for the staff to take away the pollutants and floating objects and speeding up the efficiency of taking away or collecting the pollutants and floating objects.

[0053] Sprocket three 23 is fixedly connected to the outer side wall of the reciprocating rod 20 and the reciprocating shaft 10, and a pair of sprocket three 23 are connected by chain three 24, so that the rotation of the reciprocating shaft 10 drives the reciprocating rod 20 to rotate through the sprocket three 23 and the chain three 24, so that the reciprocating rod 20 drives the reciprocating block 21 to move, and the reciprocating block 21 drives the pair of cleaning rings 22 to move. Because the pair of cleaning rings 22 are blocked by a pair of inorganic ceramic membrane filters, the pair of cleaning rings 22 and the reciprocating block 21 can only move but not rotate, so that the movement of the pair of cleaning rings 22 cleans the outer surfaces of the pair of inorganic ceramic membrane filters, thereby solving the problem of chemical residues on the inorganic ceramic membrane filters, and also solving the problem of corrosion of the outer surface of the inorganic ceramic membrane filters, so that the service life of the ceramic membrane filter assembly body 8 is increased.

[0054] When the reciprocating block 21 and the cleaning ring 22 move, the reciprocating block 21 drives the gear 5 211 to move, and the rotation of the reciprocating rod 20 drives the gear 5 211 to rotate, so that the gear 5 211 rotates and moves. The rotation of the gear 5 211 drives the pair of annular racks 216 to rotate, and the rotation of the pair of annular racks 216 drives the two sets of gears 8 213 to rotate, thereby driving the two sets of circular rods 212 to rotate, so that the two sets of circular rods 212 drive the multiple sets of vibration rods 214 and vibration balls 215 to rotate, so that the vibration balls 215 knock on a pair of inorganic The outer surface of the ceramic membrane filter vibrates. Because the vibrating ball 215 moves and rotates while striking, the outer surface of the pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8 can be uniformly subjected to vibration force. When the pair of inorganic ceramic membrane filters in the ceramic membrane filter assembly body 8 are vibrated, the vibration loosens the pollutants on the membrane surface through mechanical energy transmission. Combined with flushing or backflushing operations, the pollutant discharge efficiency can be significantly improved. Ceramic membrane assemblies often adopt cross-flow filtration, and the fluid flows through the membrane surface at high speed, forming a shear force to flush the pollutants. Vibration can further enhance this shear effect, making it easier for hard scale (such as inorganic salt crystals) or soft scale (such as organic matter) deposited on the membrane surface to fall off, reducing concentration polarization. When dust or particles accumulate on the membrane surface to form a filter cake layer, vibration can destroy the integrity of the filter cake structure, breaking it into small pieces and falling off, thereby reducing pollutant accumulation, extending membrane life, reducing energy consumption and operating costs, and improving treatment stability and safety.

[0055] Since chain 1 147, chain 2 492 and a pair of gear 2 145 are located in the sealed shell 30, and gear 1 156 and rack 1 157 are located at a high position, sewage and pollutants and floating objects in the sewage are not easily adhered to, and pollutants, floating objects and sewage are not easily corroded by the transmission mechanism of the device, thereby making the device more stable in operation, increasing the life of the transmission mechanism of the device, and reducing the probability of failure of the transmission mechanism of the device.
