[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Please see Figures 1-8As shown, a backwash-type dual-pressure ceramic membrane filtration device for wastewater treatment includes a base 1; a tank 2 is fixedly connected to the top of the outer wall of the base 1; a pump body 45 is fixedly connected to the top of the outer wall of the base 1; the input end of the pump body 45 is connected to the tank 2 through a first circular pipe; a water supply pipe 3 is provided at the output end of the pump body 45; an inorganic ceramic membrane filter 4 is provided at one end of the outer wall of the water supply pipe 3; an output pipe 5 is provided at one end of the outer wall of the inorganic ceramic membrane filter 4; an inorganic ceramic membrane filter 6 is provided on the outer wall of the water supply pipe 3 through a connecting pipe 1; the inorganic ceramic membrane filter 6... The output pipe 5 is connected to the connecting pipe 2; the output pipe 5, water supply pipe 3, connecting pipe 1 and connecting pipe 2 are all equipped with electrically controlled valves; a set of placement plates 7 are fixedly connected to the inner side walls of inorganic ceramic membrane filter 1 4 and inorganic ceramic membrane filter 2 6; a rotating rod 8 is rotatably connected to one end of the outer wall of the placement plate 7; a set of water turbine blades 9 are fixedly connected to the outer side wall of the rotating rod 8; a set of square plates 10 are fixedly connected to the outer side wall of the rotating rod 8; a set of agitating plates 12 are provided on one side of the outer wall of each set of square plates 10 via a circular rod 11, and multiple sets of agitating plates 12 are located at a set of water turbine blades. When the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6 needs cleaning, water from tank 2 is pumped through pump body 45 to the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6 for backwashing. During backwashing, the water impacts the water impeller blades 9 inside the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6, causing the water flow to rotate the water impeller blades 9. The water impeller blades 9 then rotate the rotating rod 8 and the square plate 10, which in turn rotate the circular rod 11 and the agitator plate 12. At this time, the water is agitated, causing... The rotating water creates a spiral flow field, generating stronger shear force and turbulence. This effectively removes contaminants from the surface and inner wall of the ceramic membrane, especially sticky organic matter and colloidal particles, significantly reducing membrane fouling. The rotating water flow can cover all areas within the device, including corners and gaps that are difficult to reach with traditional backwashing, preventing localized accumulation of contaminants, reducing the risk of equipment failure, and delaying membrane flux decay through more thorough backwashing, thus reducing the frequency of chemical cleaning and extending the service life of the ceramic membrane. Furthermore, because this device uses water flow as its power source, it is more environmentally friendly and energy-efficient.

[0031] A square shell 25 is fixedly connected to the top of the outer wall of both the water supply pipe 3 and the connecting pipe 1, and a pair of square shells 25 are respectively connected to the water supply pipe 3 and the connecting pipe 1; a transmission rod 26 is rotatably connected to the opposite side of the inner wall of each pair of square shells 25, and the opposite ends of the outer walls of each pair of transmission rods 26 pass through the pair of square shells 25; a third bevel gear 27 is fixedly connected to the end of each pair of transmission rods 26 that passes through the outer wall of the square shells 25; a set of transmission gears is fixedly connected to the outer wall of the end of each pair of transmission rods 26 located inside the square shells 25. Moving plate 28; the top of the outer wall of the base 1 is rotatably connected to a pair of reciprocating rods 29 via a pair of connecting blocks; a fourth bevel gear 30 is fixed to one end of the outer wall of each pair of reciprocating rods 29, and the pair of fourth bevel gears 30 mesh with a pair of third bevel gears 27 respectively; a reciprocating plate 31 is provided on the outer wall of each pair of reciprocating rods 29; a cleaning plate 32 is provided on one side of the outer wall of each pair of reciprocating plates 31, and the cleaning plate 32 is ring-shaped; the inner sidewalls of the pair of cleaning plates 32 are respectively connected to the inorganic ceramic membrane filter. The outer walls of filter 4 and inorganic ceramic membrane filter 6 are in contact with each other. When water enters the water supply pipe 3 or connecting pipe 1, and then enters inorganic ceramic membrane filter 4 or inorganic ceramic membrane filter 6 through the water supply pipe 3 and connecting pipe 1, because a portion of each of the two sets of transmission plates 28 is located inside inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6 respectively, the flow of water impacts the transmission plates 28, causing the transmission plates 28 to rotate. The transmission plates 28 drive the transmission rod 26 to rotate, and the transmission rod 26 drives the fourth bevel gear 30 to rotate through the third bevel gear 27, thereby driving the reciprocating rod 29 to rotate. The reciprocating rod 29 drives the reciprocating plate 31 to reciprocate, and the reciprocating plate 31 drives the cleaning plate 32 to reciprocate, thereby cleaning the outer surfaces of inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6. This cleans both the inner and outer walls of inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6, increasing their service life.

[0032] A set of connecting rods 23 is fixedly connected to the outer wall of the rotating rod 8; a cleaning strip 24 is fixedly connected to one end of the outer wall of each set of connecting rods 23; multiple sets of cleaning strips 24 are in contact with the inner walls of inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6 respectively. When the rotating rod 8 rotates, the rotating rod 8 drives the connecting rods 23 to rotate, and the connecting rods 23 drive the cleaning strips 24 to rotate, so that the rotation of the cleaning strips 24 scrapes away the impurities adhering to the inner walls of inorganic ceramic membrane filter 4 or inorganic ceramic membrane filter 6, so that the cleaning strips 24 clean the inner walls of inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6, and the spiral water flow cleans the membranes inside inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6, so that inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6 are more thoroughly cleaned.

[0033] A first annular rack 13 is fixedly connected to one side of the outer wall of the placement plate 7; a set of circular rods 11 are rotatably connected to one side of the outer wall of a set of square plates 10; multiple sets of stirring plates 12 are fixedly connected to the outer wall of the set of circular rods 11; one end of the outer wall of the set of circular rods 11 passes through the set of square plates 10; a first gear 14 is fixedly connected to one end of the set of circular rods 11 that passes through the outer wall of the square plates 10, and the set of first gears 14 meshes with the first annular rack 13. When the rotating rod 8 drives the square plates 10, the set of circular rods 11, and the stirring plates 12 to rotate around the axis of the rotating rod 8, the circular rods 11 simultaneously drive the first gears 14 on the circular rods 11. 4. Rotation: Since a set of first gears 14 mesh with the first annular rack 13, and the first annular rack 13 is fixed and rotates, when the first gear 14 rotates, it drives the circular rod 11 to rotate, causing the agitator 12 to rotate. This, in turn, coordinates with the agitator 12 to rotate around the axis of the rotating rod 8, thereby increasing the rotational force of the spiral flow field formed by the agitator 12 driving the water to rotate. At the same time, a large spiral flow field is formed, and within the large spiral flow field, there is also a set of medium spiral flow fields. This allows for more effective removal of contaminants from the surface and inner wall of the ceramic membrane, preventing local accumulation of contaminants and making rinsing more thorough.

[0034] A ring plate 33 is fixedly connected to one side of the outer wall of the cleaning plate 32; a set of reciprocating rods 34 are rotatably connected to one side of the outer wall of the ring plate 33 via a set of square plates; a fifth gear 35 is fixedly connected to one end of the outer wall of each set of reciprocating rods 34; a reciprocating block 36 is provided on the outer wall of each set of reciprocating rods, and one side of the outer wall of each set of reciprocating blocks 36 is in contact with one side of the outer wall of the ring plate 33; a vibrating ball 37 is fixedly connected to one side of the outer wall of the reciprocating block 36; a pair of placement strips 38 are provided at the top of the outer wall of the base 1 via a pair of arc plates, and the placement strips 38 are in the shape of a ring; a set of fifth racks 39 are fixedly connected to one side of the outer wall of the placement strips 38, and the set of fifth racks 39 are slidably connected to the cleaning plate 32; the set of fifth racks 39 meshes with a set of fifth gears 35 respectively. When the cleaning plate 32 reciprocates, the cleaning plate 32 drives the ring plate 33 to reciprocate, and the ring plate 33 drives the set of reciprocating rods 34 and the fifth gears 35 to reciprocate. A set of fifth gears 35 mesh with each other, and the fifth rack 39 is fixed. When the fifth gears 35 move, the fifth rack 39 rotates, thereby driving a set of reciprocating rods 34 to rotate. The reciprocating rods 34 drive the reciprocating block 36 to move up and down, and the reciprocating block 36 drives the vibrating ball 37 to move up and down. The vibrating ball 37 continuously strikes the outer walls of the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6, causing them to vibrate. The vibration not only makes it easier to clean impurities on the outer surfaces of the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6, but also causes the membranes inside the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6 to vibrate. With the assistance of vibration, the contaminants adhering to the membranes are more easily washed away by water, thereby further improving the cleaning efficiency and cleaning effect of the device on the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6.

[0035] A second annular rack 15 is fixedly connected to the outer wall of the square plate 10; a square through groove 16 is opened on one side of the outer wall of a set of agitating plates 12; a set of rotating rods 17 is rotatably connected to one side of the inner wall of a set of square through grooves 16, and multiple sets of rotating rods 17 pass through a set of agitating plates 12 respectively; an auxiliary plate 18 is fixedly connected to the outer wall of one end of multiple sets of rotating rods 17 located in the square through grooves 16; a second gear 19 is fixedly connected to one end of multiple sets of rotating rods 17 passing through the outer wall of the agitating plate 12; multiple sets of second gears 19 mesh with each other; a set of second gears 19 near the inner side of multiple sets of second gears 19 meshes with the second annular rack 15. When the circular rod 11 drives the agitating plate 12 to rotate, the agitating plate 12 drives the rotating rods 17 to rotate. 7 and multiple sets of auxiliary plates 18 rotate, and the auxiliary plates 18 drive the second gear 19 to rotate. Since the set of second gears 19 closest to the inner side meshes with the second ring rack 15 and the second ring rack 15 is in a fixed state, when the set of second gears 19 rotates, it drives the rotation of the second ring rack 15, thereby driving the rotation of multiple sets of second gears 19. This causes the multiple sets of rotating rods 17 to drive the multiple sets of auxiliary plates 18 to rotate. As a result, the rotation of the multiple sets of auxiliary plates 18 strengthens the spiral flow field and forms multiple small spiral flow fields, thereby further strengthening the shear force of the water. When the water cleans the membrane in the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6, the cleaning efficiency and effect are further improved.

[0036] A seventh annular rack 40 is fixedly connected to the outer wall of the cleaning plate 32; a seventh gear 41 is rotatably connected to one side of the outer wall of the reciprocating plate 31, and the seventh gear 41 is slidably connected to the reciprocating rod 29; the seventh gear 41 and the seventh annular rack 40 mesh with each other; the placement strip 38 is slidably connected to the arc plate; the reciprocating plate 31 is slidably connected to the cleaning plate 32. When the reciprocating rod 29 rotates, the reciprocating rod 29 drives the seventh gear 41 to rotate, and the reciprocating plate 31 drives the seventh gear 41 to slide on the reciprocating rod 29, so that the seventh gear 41 moves and rotates at the same time, always meshing with the seventh annular rack 40 on the cleaning plate 32, so that when the seventh gear 41 rotates, it drives the seventh annular rack 40 to rotate, so that the seventh annular rack 40 rotates. The cleaning plate 32 and the annular plate 33 are rotated by the cleaning plate 40. When the cleaning plate 32 rotates, it drives the placement bar 38 to rotate through a set of fifth racks 39, so that the placement bar 38 slides on the inner wall of the arc plate. The fifth rack 39 is always in mesh with the fifth gear 35. At this time, the vibrating ball 37 moves and strikes while rotating, so that the outer surfaces of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6 can be subjected to uniform vibration. The uniform vibration force of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6 assists the cleaning bar 24, the rotating water flow and the cleaning plate 32 to better clean the inner and outer walls of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6.

[0037] An annular shell 20 is fixedly connected to the outer wall of the first annular rack 13; a circular plate 21 is rotatably connected to one end of the outer wall of the annular shell 20, and the circular plate 21 is rotatably connected to a set of circular rods 11; the circular plate 21 and the annular shell 20 form a sealed space 1; the first annular rack 13 and the first gear 14 are both located in the sealed space 1; a sealed shell 22 is rotatably connected to the outer wall of the second annular rack 15; the sealed shell 22 is rotatably connected to multiple sets of rotating rods 17, and multiple sets of gears 2 are all located in the sealed shell 22. By having the first annular rack 13 and the first gear 14 both located in the sealed space 1, and multiple sets of gears 2 all located in the sealed shell 22, the transmission mechanism inside the device is sealed, preventing water from being trapped in the gears and racks inside the device, thereby further improving the service life of the gears and racks in the transmission mechanism inside the device.

[0038] Example 2:

[0039] Please see Figure 1 As shown, an air compressor body 42 is fixedly connected to the top of the outer wall of the base 1; an air storage tank 43 is fixedly connected to the top of the outer wall of the base 1; the output end of the air compressor body 42 is connected to the air storage tank 43 through an air pipe 1; the air storage pipe is connected to the tank 2 through an air pipe 2. When the device performs backwashing, the air compressor compresses the air to the required pressure and then delivers the air to the air storage pipe, so that the air in the air storage pipe enters the tank 2 through the air pipe 2 and mixes with the water. At this time, the compressed air is buffered by the air storage tank 43, and the airflow is more uniform. When mixed with the backwash water, it can form a stable bubble flow, which enhances the scrubbing and peeling effect on the surface of the ceramic membrane. In combination with the rotating water flow, the cleaning effect and cleaning efficiency of the device are better, while also saving energy and being more environmentally friendly.

[0040] In use, when the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6 needs cleaning, water from the tank 2 is pumped into the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6 via the pump body 45 for backwashing. During backwashing, the water impacts the waterwheel blades 9 inside the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6, causing the water flow to rotate the waterwheel blades 9. The waterwheel blades 9 then rotate the rotating rod 8 and the square plate 10, which in turn rotate the circular rod 11 and the agitator plate 12. At this time, the water is agitated. The rotating water creates a spiral flow field, generating stronger shear force and turbulence. This effectively removes contaminants from the surface and inner wall of the ceramic membrane, especially sticky organic matter and colloidal particles, significantly reducing membrane fouling. The rotating water flow can cover all areas within the device, including corners and gaps that are difficult to reach with traditional backwashing, preventing localized accumulation of contaminants, reducing the risk of equipment failure, and delaying membrane flux decay through more thorough backwashing, thus reducing the frequency of chemical cleaning and extending the service life of the ceramic membrane. Furthermore, because this device uses water flow as its power source, it is more environmentally friendly and energy-efficient.

[0041] When the rotating rod 8 drives the square plate 10, a set of circular rods 11, and the agitator 12 to rotate around the axis of the rotating rod 8, the circular rods 11 simultaneously drive the first gear 14 on the circular rods 11 to rotate. Since the set of first gears 14 are all meshed with the first ring rack 13, and the first ring rack 13 is fixed and rotating, when the first gear 14 rotates, it drives the circular rods 11 to rotate, causing the agitator 12 to rotate. This, in turn, works with the agitator 12 to rotate around the axis of the rotating rod 8, thereby increasing the rotational force of the spiral flow field formed by the agitator 12 driving the water to rotate. At the same time, a large spiral flow field is formed, and within the large spiral flow field, there is also a set of medium spiral flow fields. This allows for more effective removal of contaminants from the surface and inner wall of the ceramic membrane, preventing local accumulation of contaminants and making rinsing more thorough.

[0042] When the circular rod 11 drives the agitator plate 12 to rotate, the agitator plate 12 drives the rotating rod 17 and multiple sets of auxiliary plates 18 to rotate. The auxiliary plates 18 drive the second gear 19 to rotate. Since the set of second gears 19 closest to the inner side meshes with the second ring rack 15 and the second ring rack 15 is in a fixed state, when the set of second gears 19 rotates, it drives the rotation of the second ring rack 15, thereby driving the rotation of multiple sets of second gears 19. This causes the rotating rod 17 to drive the rotation of multiple sets of auxiliary plates 18. As a result, the rotation of the multiple sets of auxiliary plates 18 strengthens the spiral flow field and forms multiple small spiral flow fields, thereby further strengthening the shear force of the water. This further improves the cleaning efficiency and effect when the water cleans the membrane in the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6.

[0043] With the first annular rack 13 and the first gear 14 both located within the sealed space 1, and multiple sets of gears 2 all located within the sealed housing 22, the transmission mechanism within this device is sealed, preventing water from being trapped in the gears and racks within the device, thereby further extending the service life of the gears and racks in the transmission mechanism within this device.

[0044] When the rotating rod 8 rotates, it drives the connecting rod 23 to rotate, which in turn drives the cleaning strip 24 to rotate. The rotation of the cleaning strip 24 scrapes away the impurities adhering to the inner wall of the inorganic ceramic membrane filter 4 or the inorganic ceramic membrane filter 6, thus cleaning the inner walls of the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6. The spiral water flow cleans the membranes inside the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6, thereby achieving a more comprehensive cleaning of the inorganic ceramic membrane filter 4 and the inorganic ceramic membrane filter 6.

[0045] When water enters the water supply pipe 3 or connecting pipe 1, and then enters the inorganic ceramic membrane filter 4 or inorganic ceramic membrane filter 6 through the water supply pipe 3 and connecting pipe 1, because a portion of each of the two sets of transmission plates 28 is located inside the inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6 respectively, the water flow impacts the transmission plates 28, causing the transmission plates 28 to rotate. The transmission plates 28 drive the transmission rod 26 to rotate, and the transmission rod 26 drives the fourth bevel gear 30 to rotate through the third bevel gear 27, thereby driving the reciprocating rod 29 to rotate. The reciprocating rod 29 drives the reciprocating plate 31 to reciprocate, and the reciprocating plate 31 drives the cleaning plate 32 to reciprocate, thereby cleaning the outer surface of the inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6. This cleans both the inner and outer walls of the inorganic ceramic membrane filter 4 and inorganic ceramic membrane filter 6, increasing their service life.

[0046] When the cleaning plate 32 reciprocates, it drives the annular plate 33 to reciprocate. The annular plate 33 drives a set of reciprocating rods 34 and a fifth gear 35 to reciprocate. Since a set of fifth racks 39 meshes with a set of fifth gears 35 and the fifth racks 39 are fixed, when the fifth gears 35 move, the rotation of the fifth racks 39 drives the set of reciprocating rods 34 to rotate. This causes the reciprocating rods 34 to drive the reciprocating block 36 to reciprocate up and down, which in turn drives the vibrating ball 37 to reciprocate up and down. This causes the vibrating ball 37 to continuously vibrate against the inorganic ceramic membrane filter 4. The outer wall of the inorganic ceramic membrane filter 26 is struck, causing the inorganic ceramic membrane filters 14 and 26 to vibrate. This vibration not only makes it easier to clean impurities on the outer surfaces of the inorganic ceramic membrane filters 14 and 26, but also causes the membranes inside the inorganic ceramic membrane filters 14 and 26 to vibrate. With the assistance of vibration, the contaminants adhering to the membranes are more easily washed away by water, thereby further improving the cleaning efficiency and cleaning effect of this device on the inorganic ceramic membrane filters 14 and 26.

[0047] When the reciprocating rod 29 rotates, it drives the seventh gear 41 to rotate, and the reciprocating plate 31 drives the seventh gear 41 to slide on the reciprocating rod 29, so that the seventh gear 41 moves and rotates at the same time, always meshing with the seventh annular rack 40 on the cleaning plate 32. When the seventh gear 41 rotates, it drives the seventh annular rack 40 to rotate, which in turn drives the cleaning plate 32 and the annular plate 33 to rotate. When the cleaning plate 32 rotates, it drives the placement bar 38 to rotate through a set of fifth racks 39, so that the placement bar 38 rotates. The bar 38 slides on the inner wall of the arc-shaped plate, so that the fifth rack 39 is always engaged with the fifth gear 35. At this time, the vibrating ball 37 moves, strikes, and rotates at the same time, so that the outer surfaces of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6 can be subjected to uniform vibration. The uniform vibration force of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6 assists the cleaning bar 24, the rotating water flow, and the cleaning plate 32 to better clean the inner and outer walls of the inorganic ceramic membrane filter 1 4 and the inorganic ceramic membrane filter 2 6.

[0048] When this device performs backwashing, the air is compressed to the required pressure by the air compressor and then delivered to the air storage pipe. The air in the air storage pipe enters the tank 2 through the air pipe 2 and mixes with the water. At this time, the compressed air is buffered by the air storage tank 43, and the airflow is more uniform. When mixed with the backwash water, it can form a stable bubble flow, which enhances the scrubbing and peeling effect on the surface of the ceramic membrane. In combination with the rotating water flow, the cleaning effect and cleaning efficiency of this device are better, while also saving energy and being more environmentally friendly.
