Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a cascade membrane separation treatment and reuse device for high-salinity wastewater in eco-industrial parks. Background Technology

[0002] High-salinity wastewater contains a large amount of salts, such as sodium chloride, sodium sulfate, calcium and magnesium salts, which makes the total dissolved solids concentration of the wastewater much higher than that of ordinary wastewater.

[0003] Chinese Patent Publication No. CN118545779A discloses a membrane separation treatment device and its usage method for high-concentration salinity wastewater, comprising: a separation treatment box, wherein an inlet pipe and an outlet pipe are installed on the top and lower side of the separation treatment box, a lifting water tank assembly is installed inside the separation treatment box, and a filter assembly is installed inside the separation treatment box below the lifting water tank assembly.

[0004] In the above technical solution, by designing output components, filter components, and lifting water tank components, the entire membrane is divided into multiple groups to achieve localized filtration, thus avoiding the inconvenience of using and maintaining the entire membrane. In some existing high-salt wastewater treatment devices, high-salt wastewater needs to be filtered through a filter membrane during the treatment process. However, when the filter membrane is used to treat wastewater for a long time, the surface of the filter membrane becomes clogged, affecting the filtration area of ​​the filter membrane for wastewater. Moreover, when cleaning the filter membrane, the addition of high-salt wastewater needs to be stopped, which cannot guarantee the continuous treatment of high-salt wastewater and affects the treatment efficiency of the filter membrane for high-salt wastewater. In addition, after the impurities filtered by the filter membrane are collected, local coagulation will occur, making it difficult to clean the impurities. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) When the high-salinity wastewater cascade membrane separation treatment and reuse device in this eco-industrial park is in operation, the high-salinity wastewater is introduced into the inlet pipe, and the motor rotates, causing the rotating shaft to rotate. This rotation of the rotating shaft, in turn, causes multiple inclined connecting frames to rotate simultaneously. The rotation of the inclined connecting frames causes two horizontal frame plates to rotate, which in turn causes the fixed plate and flexible brushes to rotate. The multiple flexible brushes simultaneously rotate to clean and sweep away impurities from the surface of the inclined filter membrane. During the movement of the fixed bevel gear, the rotation of the bevel gear causes the rotating shaft to rotate, which in turn causes the rollers to rotate. The rotating rollers, along with the curved conveyor bars, clean and transport the leveled impurities. The rotating conveyor bars transport the impurities on the surface of the inclined filter membrane to the bottom of the inclined filter membrane. Compared with traditional high-salt wastewater treatment devices, this separation and treatment equipment can clean the inclined filter membrane without stopping the addition of high-salt wastewater during the high-salt wastewater treatment process, thus improving the efficiency of the separation and treatment equipment in treating high-salt wastewater. Moreover, the slope design of the inclined filter membrane prevents the inclined filter membrane from being locally blocked by high-salt wastewater impurities, thereby ensuring the wastewater treatment efficiency of the inclined filter membrane.

[0016] 2) When the high-salt wastewater cascade membrane separation treatment and reuse device in this eco-industrial park is in use, the conveyor bar rotates to transport impurities on the surface of the inclined membrane filter to the bottom of the inclined membrane filter. As the inclined plate moves with the arc-shaped shell, it also carries the auxiliary scraper. The auxiliary scraper scrapes the impurities accumulated at the bottom of the inclined membrane filter into the annular chamber. In order to prevent high-salt impurities from easily condensing locally inside the annular chamber, the horizontal frame plate rotates and carries the support shaft. The movement of multiple support shafts carries multiple rotating wheels to roll inside the annular chamber. The rotation of the outer plate and the inner plate carries the first and second gathering plates to move. The movement of the first and second gathering plates gathers the impurities inside the annular chamber. Then the rotating wheels roll inside the annular chamber to crush the gathered impurities, preventing high-salt impurities from easily condensing locally inside the annular chamber.

[0017] 3) When the high-salt wastewater cascade membrane separation treatment and reuse device in this eco-industrial park is in use, the rotor rolls inside the annular chamber to crush the aggregated impurities. The outer plate and the inner plate also move along with two vertical columns and an inclined scraper. The inclined scraper scrapes away the crushed impurities. The scraped impurities are discharged through the discharge tank, which facilitates the cleaning and discharge of impurities in the high-salt wastewater and further improves the efficiency of the separation treatment equipment in treating high-salt wastewater.

[0020] Please see Figure 1 - Figure 12The eco-industrial park's high-salinity wastewater cascade membrane separation treatment and reuse device includes a separation treatment unit 1, which treats high-salinity wastewater. A fixed plate 2 is fixedly installed on the inner wall of the separation treatment unit 1, and an inclined membrane filter 3 is fixedly installed on the surface of the fixed plate 2. The inclined membrane filter 3 is a conventional membrane filter in existing technology. The high-salinity wastewater is filtered along the slope of the inclined membrane filter 3 to prevent local clogging of the inclined membrane filter 3 by impurities. An annular chamber 4, connected to the inclined membrane filter 3, is fixedly installed on the outer surface of the inclined membrane filter 3. The annular chamber 4 is used for collecting and treating impurities from the high-salinity wastewater. A rotatable shaft 6 is located in the middle of the separation treatment unit 1, and multiple inclined connecting frames 7 are fixedly connected to the surface of the shaft 6. Two horizontal blocks are respectively installed at the bottom of each inclined connecting frame 7. A mounting plate 8 is formed, with a fixing plate 9 fixedly installed between two horizontal mounting plates 8. The slope of the fixing plate 9 is the same as the slope of the inclined filter membrane 3, ensuring that the flexible brush 10 contacts the surface of the inclined filter membrane 3. Several flexible brushes 10 for cleaning the surface of the inclined filter membrane 3 are fixedly installed on the bottom surface of the fixing plate 9. The flexible brushes 10 are conventional flexible brushes in the prior art. The surface of one horizontal mounting plate 8 is fixedly connected to the bottom surface of the inclined connecting frame 7. An arc-shaped shell 13 is fixedly installed between the two horizontal mounting plates 8. When the conveyor bar 12 conveys impurities, the arc-shaped shell 13 is designed to prevent impurities from being thrown off midway. The arc-shaped shell 13 is located on one side of the fixing plate 9. A rotating roller 11 is rotatably connected inside the arc-shaped shell 13. The surface of the rotating roller 11 is fixedly installed with... Multiple conveyor bars 12 are used to clean impurities from the surface of the inclined filter membrane 3. The conveyor bars 12 rotate with the rollers 11 to transport the impurities. Two inclined plates 14 are fixedly installed on the surface of the arc-shaped shell 13. The design of the inclined plates 14 allows the cleaned impurities to be flattened by the inclined plates 14, which facilitates the transport of impurities by the conveyor bars 12. The annular chamber 4 has multiple rotating wheels 15 that roll around it. The rotating wheels 15 can crush locally condensed impurities. External plates 16 and internal plates 17 are respectively installed on both sides of the rotating wheels 15. Gathering plates 18 and 19 are fixedly installed on the bottom surfaces of the external plates 16 and 17 to gather impurities inside the annular chamber 4. The movement of gathering plates 18 and 19 affects the internal structure of the annular chamber 4. Impurities are gathered together. While high-salt wastewater is introduced into the inlet pipe 33, the motor 37 rotates, causing the rotating shaft 6 to rotate. This, in turn, causes multiple inclined connecting frames 7 to rotate simultaneously. The inclined connecting frames 7 rotate, causing two horizontal frame plates 8 to rotate. The two horizontal frame plates 8 rotate, causing the fixed plate 9 and flexible brushes 10 to rotate. The multiple flexible brushes 10 simultaneously rotate to clean and sweep away impurities from the surface of the inclined filter membrane 3. During the movement of the fixed bevel gear 5, the bevel gear 22 rotates, causing the rotating shaft 21 to rotate. This rotating shaft 21 then rotates, causing the rotating roller 11 to rotate. The rotating roller 11 rotates, causing the curved conveyor strip 12 to rotate, cleaning and conveying the leveled impurities. The rotating conveyor strip 12 transports the impurities from the surface of the inclined filter membrane 3 to the bottom of the inclined filter membrane 3.Compared to traditional high-salinity wastewater treatment devices, this separation and treatment equipment 1 can clean the inclined membrane filter 3 without stopping the addition of high-salinity wastewater during the high-salinity wastewater treatment process, thus improving the treatment efficiency of the separation and treatment equipment 1 for high-salinity wastewater. Furthermore, the slope design of the inclined membrane filter 3 prevents localized clogging by high-salinity wastewater impurities, thereby ensuring the treatment efficiency of the inclined membrane filter 3. The rotating conveyor bar 12 transports impurities from the surface of the inclined membrane filter 3 to the bottom of the inclined membrane filter 3. The inclined plate 14, moving along with the arc-shaped shell 13, also carries the auxiliary scraper 26. The motion of plate 6 scrapes the impurities accumulated at the bottom of the inclined filter membrane 3 into the annular chamber 4. To prevent high-salt impurities from easily condensing locally inside the annular chamber 4, the rotation of the cross plate 8 also moves the support shaft 23. The movement of multiple support shafts 23 causes multiple rotating wheels 15 to roll inside the annular chamber 4. The rotation of the outer plate 16 and the inner plate 17 moves the first gathering plate 18 and the second gathering plate 19. The movement of the first gathering plate 18 and the second gathering plate 19 gathers the impurities inside the annular chamber 4. Then, the rotating wheels 15 roll inside the annular chamber 4 to crush the gathered impurities, preventing high-salt impurities from easily condensing locally inside the annular chamber 4.

[0021] Please see Figure 5 - Figure 12 The number of rotating wheels 15 is the same as the number of fixed plates 9. Vertical frames 20 are fixedly installed on both ends of the arc-shaped shell 13. The two ends of the rotating roller 11 are rotatably connected to the inner surfaces of the vertical frames 20. A rotating shaft 21 is fixedly installed on one end of the rotating roller 11. One end of the rotating shaft 21 passes through one of the vertical frames 20 and is rotatably connected to one of the vertical frames 20. A bevel gear 22 is fixedly installed on one end of the rotating shaft 21. A gear meshing with the bevel gear 22 is fixedly installed on the inner surface of the inclined filter membrane 3. The fixed bevel gear 5 meshes with the bevel gear 22 to ensure the continuous rotation of the bevel gear 22. The rotating wheel 15 rolls inside the annular chamber 4 to crush the aggregated impurities. The outer plate 16 and the inner plate 17 also move with two vertical columns 27 and the inclined scraper 28. The inclined scraper 28 moves to scrape away the crushed impurities. The scraped impurities are discharged through the discharge tank 24, which facilitates the cleaning and discharge of impurities in high-salt wastewater and further improves the efficiency of the separation and treatment equipment 1 in treating high-salt wastewater.

[0022] Please see Figure 9 - Figure 12 A support shaft 23 is fixedly connected to the surface of the cross plate 8 away from the inclined frame 7. The support shaft 23 is rotatably connected to the wheel 15. The outer plate 16 and the inner plate 17 are fixedly connected to the two sides of the support shaft 23 respectively.

Multiple discharge boxes 25 connected to the discharge slots 24 are fixedly installed on the surface of the annular chamber 4. The bottom of the discharge box 25 extends to the outside of the separation and processing equipment 1. An auxiliary scraper 26 for guiding impurities into the annular chamber 4 is fixedly installed on the bottom surface of one end of the inclined plate 14. The auxiliary scraper 26 is inclined. The conveyor bar 12 rotates to transport the impurities on the surface of the inclined filter membrane 3 to the bottom of the inclined filter membrane 3. As the inclined plate 14 moves with the arc shell 13, it also moves with the auxiliary scraper 26. The movement of the auxiliary scraper 26 scrapes the impurities accumulated at the bottom of the inclined filter membrane 3 into the annular chamber 4.

[0024] Please see Figure 7 - Figure 12 Vertical columns 27 are fixedly installed on the bottom surface of one end of the outer plate 16 and the inner plate 17. An inclined scraper 28 is fixedly installed on the bottom surface of the two vertical columns 27. The inclined scraper 28 matches the annular chamber 4 and is inclined towards the discharge groove 24 inside the annular chamber 4.

[0025] Please see Figure 5 - Figure 8 A conical slope plate 29 is provided on the inner side of the fixed conical tooth 5. The slope of the conical slope plate 29 is the same as that of the fixed conical tooth 5 to prevent unfiltered high-salt wastewater from leaking down from the conical slope plate 29. The slope of the conical slope plate 29 is in contact with the slope of the fixed conical tooth 5. When high-salt wastewater splashes onto the surface of the conical slope plate 29, the high-salt wastewater flows down along the conical slope plate 29 and the fixed conical tooth 5. Multiple connecting frames 30 are fixedly installed between the conical slope plate 29 and the fixed conical tooth 5. The rotating shaft 6 is rotatably connected to the conical slope plate 29.

[0026] Please see Figure 3 - Figure 5 Multiple stirring devices 31 are fixedly installed on the bottom surface of the rotating shaft 6. A collection plate 32 is fixedly installed on the inner wall of the separation and treatment equipment 1. The collection plate 32 is used for collecting high-salt wastewater. The collection plate 32 is located above the fixed plate 2. An inlet pipe 33 connected to the collection plate 32 is fixedly installed on the surface of the collection plate 32. One end of the inlet pipe 33 extends to the outside of the separation and treatment equipment 1.

[0027] Please see Figure 1 - Figure 5 The bottom surface of the collector plate 32 is fixedly equipped with multiple branch pipes 34 that are connected to it, and the outlet of the branch pipes 34 corresponds to the upper part of the slope of the inclined filter membrane device 3.

[0028] A matching cover plate 35 is fixedly installed on the top surface of the separation and processing equipment 1. A mounting bracket 36 is fixedly installed on the surface of the cover plate 35. A motor 37 is fixedly installed on the surface of the mounting bracket 36. The motor 37 is a conventional motor 37 in the prior art. The output end of the motor 37 is fixedly connected to the rotating shaft 6. A base 40 is fixedly installed on the bottom surface of the separation and processing equipment 1. A discharge pipe 41 communicating with the base 40 is fixedly installed in the middle of the bottom surface of the separation and processing equipment 1.

[0029] A support frame 38 is fixedly mounted on the surface of the separation and processing equipment 1. A controller 39 is fixedly mounted on the surface of the support frame 38. The controller 39 is a conventional controller 39 in the prior art. The controller 39 controls the start and stop of the motor 37, which is the prior art and will not be described in detail here. The controller 39 is electrically connected to the motor 37 through wires.

[0030] The usage steps of this invention are as follows: When using the high-salinity wastewater cascade membrane separation treatment and reuse device in this eco-industrial park, the high-salinity wastewater is first introduced into the inlet pipe 33 via an existing pump. The wastewater then enters the collection plate 32 through the inlet pipe 33 and is discharged through multiple branch pipes 34. Since the outlet of the branch pipes 34 corresponds to the upper part of the slope of the inclined membrane filter 3, the high-salinity wastewater is filtered along the slope of the inclined membrane filter 3, preventing partial clogging of the inclined membrane filter 3 by impurities. The discharged high-salinity wastewater is filtered by the inclined membrane filter 3. Simultaneously with the high-salinity wastewater entering the inlet pipe 33, the controller 39 is operated. The controller 39 controls the motor 37 to rotate, which in turn rotates the shaft 6, causing the shaft 6 to rotate. Multiple inclined frames 7 rotate simultaneously, which in turn rotates two horizontal frame plates 8. The rotation of the two horizontal frame plates 8, in turn, rotates the fixed plate 9 and the flexible brush 10. The simultaneous rotation of the multiple flexible brushes 10 cleans and sweeps away impurities on the surface of the inclined filter membrane 3. The rotation of the two horizontal frame plates 8 also moves the arc-shaped shell 13 and the roller 11. The movement of the arc-shaped shell 13 moves the two inclined plates 14, causing the cleaned impurities to be flattened by the inclined plates 14. The movement of the roller 11 moves the rotating shaft 21 and the bevel gear 22. During the movement of the fixed bevel gear 5, the rotation of the bevel gear 22 causes the rotating shaft 21 to rotate, which in turn causes the roller 11 to rotate. The rotation of the roller 11 causes the curved conveyor strip 12 to rotate, cleaning and conveying the flattened impurities. The conveyor bar 12 rotates, transporting impurities from the surface of the inclined filter membrane 3 to the bottom of the inclined filter membrane 3. The inclined plate 14, following the movement of the arc-shaped shell 13, also moves the auxiliary scraper 26. The auxiliary scraper 26 scrapes the impurities accumulated at the bottom of the inclined filter membrane 3 into the annular chamber 4. High-salt impurities are prone to localized condensation inside the annular chamber 4. The horizontal frame plate 8 rotates, also moving the support shaft 23. Multiple support shafts 23 move, causing multiple rotating wheels 15 to roll inside the annular chamber 4. Simultaneously, the support shafts 23 move, causing the outer plate 16 and the inner plate 17 to rotate around the inner wall of the annular chamber 4. The rotation of the outer plate 16 and the inner plate 17 moves the first gathering plate 18 and the second gathering plate 19. The movement of the first gathering plate 18 and the second gathering plate 19 cleans the impurities inside the annular chamber 4. The impurities are gathered together, and then the rotating wheel 15 rolls inside the annular chamber 4 to crush the gathered impurities. The outer plate 16 and the inner plate 17 also move along with two vertical columns 27 and the inclined scraper 28. The inclined scraper 28 scrapes away the crushed impurities. The scraped impurities are discharged into the discharge box 25 through the discharge trough 24, and finally discharged to the outside of the separation treatment equipment 1 through the discharge box 25. After being filtered by the inclined membrane filter 3, the high-salt wastewater enters the bottom of the separation treatment equipment 1. The rotating shaft 6 rotates, driving the stirring device 31 to rotate and stir the wastewater. Finally, it is discharged through the discharge pipe 41. In this scheme, while the high-salt wastewater enters the inlet pipe 33, the motor 37 rotates, driving the rotating shaft 6 to rotate, which in turn causes the rotating shaft 6 to rotate, driving multiple inclined connecting frames 7 to rotate simultaneously.The inclined frame 7 rotates, causing the two horizontal frame plates 8 to rotate. The two horizontal frame plates 8 rotate, causing the fixed plate 9 and flexible brushes 10 to rotate. Multiple flexible brushes 10 rotate simultaneously to clean and sweep away impurities on the surface of the inclined filter membrane 3. During the movement of the fixed bevel gear 5, the bevel gear 22 rotates, causing the rotating shaft 21 to rotate. The rotating shaft 21 rotates, causing the roller 11 to rotate. The rotating roller 11 rotates, causing the curved conveyor bar 12 to rotate, cleaning and conveying the leveled impurities. The rotating conveyor bar 12 transports the impurities on the surface of the inclined filter membrane 3 to the inclined... Compared to traditional high-salinity wastewater treatment devices, this separation and treatment equipment 1 can clean the inclined membrane filter 3 without stopping the addition of high-salinity wastewater during the high-salinity wastewater treatment process, thus improving the high-salinity wastewater treatment efficiency of the separation and treatment equipment 1. Furthermore, the slope design of the inclined membrane filter 3 prevents localized clogging by high-salinity wastewater impurities, thereby ensuring the wastewater treatment efficiency of the inclined membrane filter 3. The rotating conveyor bar 12 transports impurities from the surface of the inclined membrane filter 3 to the bottom of the inclined membrane filter 3, and the inclined plate 14 follows. During the movement of the arc-shaped shell 13, the auxiliary scraper 26 also moves. The movement of the auxiliary scraper 26 scrapes the impurities accumulated at the bottom of the inclined filter membrane 3 into the annular chamber 4. To prevent high-salt impurities from easily condensing locally inside the annular chamber 4, the rotation of the cross plate 8 also moves the support shaft 23. The movement of multiple support shafts 23 causes multiple rotating wheels 15 to roll inside the annular chamber 4. The rotation of the outer plate 16 and the inner plate 17 moves the first gathering plate 18 and the second gathering plate 19. The movement of the first gathering plate 18 and the second gathering plate 19 gathers the impurities inside the annular chamber 4. The impurities are gathered together, and then the rotating wheel 15 rolls inside the annular chamber 4 to crush the gathered impurities, preventing localized coagulation of high-salt impurities within the annular chamber 4. The rotating wheel 15 also crushes the gathered impurities inside the annular chamber 4. The outer plate 16 and the inner plate 17 also move, carrying two vertical columns 27 and an inclined scraper 28. The inclined scraper 28 scrapes away the crushed impurities, which are then discharged through the discharge trough 24. This facilitates the cleaning and discharge of impurities from the high-salt wastewater, further improving the efficiency of the separation and treatment equipment 1 in treating high-salt wastewater.
