Description

Technical Field

[0001] This invention belongs to the field of integrated filtration technology, specifically referring to an integrated filtration device based on hollow fiber membranes. Background Technology

[0002] Hollow fiber membrane modules have been widely used in water treatment and other fields due to their significant advantages such as high packing density, self-supporting structure, and low manufacturing cost. However, in practical applications, membrane fouling not only reduces membrane filtration efficiency and shortens the service life of membrane modules, but also affects the economic benefits of membrane cleaning, operation, and replacement.

[0003] Current integrated filtration equipment based on hollow fiber membranes has the following problems:

[0004] Existing filtration integration equipment based on hollow fiber membranes does not have the ability to adjust the contact area between the wastewater and the hollow fiber membrane according to the wastewater volume. Since the wastewater and the hollow fiber membrane are in vertical contact filtration, when the wastewater volume is small, the hollow fiber membrane cannot be completely submerged, causing the unsubmerged hollow fiber membrane to be in a state of air suction. The gas in the membrane pores is forcibly extracted, causing the membrane pores to collapse, close, or undergo irreversible deformation, thereby affecting the service life of the hollow fiber membrane.

[0005] Furthermore, traditional filtration integration equipment based on hollow fiber membranes does not have the ability to perform regular backwashing of hollow fiber membranes, which leads to a reduction in membrane flux and thus affects the filtration efficiency of hollow fiber membranes for wastewater.

[0006] Therefore, it cannot meet the current demand for integrated filtration equipment based on hollow fiber membranes. Summary of the Invention

[0007] To address the above issues and overcome the shortcomings of existing technologies, this solution provides an integrated filtration device based on hollow fiber membranes. This device can adjust the contact area between the wastewater and the hollow fiber membrane according to the wastewater volume, ensuring that the wastewater completely submerges the hollow fiber membrane. It can also perform regular backwashing of the hollow fiber membrane to maintain membrane flux and improve the filtration efficiency of the hollow fiber membrane for wastewater.

[0008] The technical solution adopted in this solution is as follows: This solution proposes a filtration integration device based on hollow fiber membrane, including an integrated cylinder, a support frame, a water-controlled filtrate mechanism, and an internally guided backwashing mechanism. The support frame is located on one side of the integrated cylinder, the water-controlled filtrate mechanism is located on the integrated cylinder, and the internally guided backwashing mechanism is located on the support frame. The water-controlled filtrate mechanism includes a sludge inlet component, a water pressure component, and a purification component. The sludge inlet component is located on one side of the integrated cylinder, the water pressure component is located inside the integrated cylinder, and the purification component is located between the top and bottom walls of the integrated cylinder. The internally guided backwashing mechanism includes a guide component, a water supply component, and a cleaning component. The guide component is located at the end of the support frame away from the integrated cylinder, the water supply component is located at the top of the guide component, and the cleaning component is located at the end of the water supply component close to the integrated cylinder.

[0009] As a further preferred embodiment of the present invention, the inlet assembly includes an annular pipe, an inlet valve, and a filter pipe. The annular pipe is located on the side of the support frame away from the integrated cylinder. The inlet valve is connected to the side of the annular pipe away from the support frame. The filter pipe is connected between the annular pipe and the bottom side wall of the integrated cylinder. The water pressure assembly includes a water pressure plate, a water pressure spring, and a water-blocking rubber sleeve. The water pressure plate is slidably located on the inner wall of the integrated cylinder. Multiple sets of the water-blocking rubber sleeves are connected through the upper wall of the water pressure plate. The water pressure spring is located between the upper wall of the water pressure plate and the top wall of the integrated cylinder. The water pressure spring is normally in an extended state. The purification assembly includes a fixed cylinder, hollow fiber membrane strips, a water pump, a water pumping pipe, and a drain valve. The fixed cylinders are respectively located on the top and bottom walls of the integrated cylinder. Multiple sets of hollow fiber membrane strips are connected between the fixed cylinders. The water pump is located on the side wall of the integrated cylinder. The water pumping pipe is connected through the integrated cylinder at the water pumping end and is connected to the fixed cylinder located at the bottom of the integrated cylinder. The drain valve is located at the water pumping end.

[0010] In use, the sewage pipe is connected to the inlet valve, and the sewage enters the annular pipe through the inlet valve. The sewage inside the annular pipe is discharged into the integrated cylinder below the pressure plate through the filter pipe. When a large amount of sewage enters the bottom of the integrated cylinder, the sewage squeezes the pressure plate. The pressure plate slides and rises along the inner wall of the integrated cylinder by utilizing the deformation of the pressure spring. The pressure plate drives the water-blocking rubber sleeve to slide and rise along the outer surface of the hollow fiber membrane strip, increasing the contact area between the sewage and the hollow fiber membrane strip and improving the sewage treatment capacity. The water pump draws the sewage from the integrated cylinder through the hollow fiber membrane strip. After being filtered by the hollow fiber membrane strip, the sewage enters the fixed cylinder at the bottom of the integrated cylinder. The clean water filtered inside the fixed cylinder flows into the pumping pipe and is discharged through the drain valve.

[0011] Preferably, the guiding assembly includes a guide post, a guide frame, a guide spring, a waterproof ranging sensor, a guide magnet, and a driving electromagnet. The guide post is slidably disposed at the end of the support frame away from the integrated cylinder. The guide frame is disposed on the upper wall of the guide post. The guide spring is disposed between the guide frame and the upper wall of the support frame on the outside of the guide post. The guide spring is normally in a shortened state. The waterproof ranging sensor is disposed on the bottom wall of the pressure plate. The guide magnet is disposed on the bottom wall of the guide post. The driving electromagnet is disposed at the bottom of the support frame, and the guide magnet and the driving electromagnet are arranged opposite to each other. The water supply assembly includes a water collection cylinder, a water supply pump, and a water supply telescopic pipe. The water collection cylinder is disposed on the side of the guide frame away from the guide post and is located above the integrated cylinder. The water supply pump is disposed on the side wall of the integrated cylinder. The water supply telescopic pipe is connected between the water collection cylinder and the drain end of the water supply pump. The cleaning assembly includes a cleaning tube and a sealing tube. The system comprises a block, a cleaning port, a drain trough, a drain expansion pipe, a cleaning check valve, and a sealing rubber sleeve. Multiple sets of the sealing rubber sleeves penetrate the integrated cylinder and are connected to the upper wall of the fixed cylinder at the top of the integrated cylinder. Multiple sets of cleaning capillary tubes are connected to the bottom wall of the water collection cylinder. The end of the cleaning capillary tube furthest from the water collection cylinder penetrates the sealing rubber sleeve and is located inside the hollow fiber membrane strip. The outer diameter of the cleaning capillary tube is larger than the inner diameter of the sealing rubber sleeve but smaller than the inner diameter of the hollow fiber membrane strip. The sealing rubber sleeve is tightly fitted to the outer surface of the cleaning capillary tube through its own deformation. The cleaning port is located at the end of the cleaning capillary tube furthest from the water collection cylinder. The sealing block is located on the bottom wall of the cleaning capillary tube, and the outer diameter of the sealing block is the same as the inner diameter of the hollow fiber membrane strip. The drain trough is located on the upper wall of the pressure plate and has an opening at the top. The drain expansion pipe penetrates the integrated cylinder and is connected to the bottom wall of the drain trough. The cleaning check valve is connected to the end of the drain expansion pipe furthest from the drain trough.

[0012] During use, the cleaning tube is located inside the hollow fiber membrane strip. The bottom wall of the sealing block is flush with the bottom wall of the pressure plate. The sealing block blocks the hollow fiber membrane strip above the pressure plate, so that the water pump can only pump the hollow fiber membrane strip below the pressure plate. The cut-off height of the hollow fiber membrane strip is adjusted according to the amount of sewage entering the integrated cylinder to prevent the hollow fiber membrane strip not submerged in sewage from being sucked up. When the amount of sewage entering the bottom of the integrated cylinder increases, the pressure plate rises, and the measuring end of the waterproof distance sensor is aligned with the bottom of the integrated cylinder. As the distance between them increases, the driving electromagnet receives a signal and is energized to generate magnetism. The driving electromagnet and the guide magnet are set with the same poles. The driving electromagnet is fixed at the bottom of the support frame and pushes the guide magnet through repulsion. The guide magnet drives the guide column to slide and rise along the support frame. The guide column drives the water collection cylinder to rise through the guide frame. The water collection cylinder drives the cleaning tube to drive the sealing block to rise along the inner wall of the hollow fiber membrane strip, so that the bottom wall of the sealing block always remains flush with the bottom wall of the pressure plate, ensuring that the hollow fiber membrane strip will not experience air suction.

[0013] Specifically, the integrated cylinder sidewall is equipped with a controller.

[0014] The controller is electrically connected to the water pump, the waterproof distance sensor, the drive electromagnet, and the water supply pump.

[0015] The beneficial effects achieved by this solution using the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a water-controlled filtration mechanism with an internally guided backwashing mechanism. Through the inclusion of inlet components, pressure components, purification components, guiding components, water supply components, and cleaning components, the contact area between the hollow fiber membrane strips and the wastewater can be adjusted according to the wastewater inflow rate inside the integrated cylinder. Under the pressure of the pressure plate, the blocking block can change the blocking position of the hollow fiber membrane strips according to the height of the pressure plate, ensuring that the hollow fiber membrane strips participating in the filtration operation are completely submerged in the wastewater. The sealing block blocks the hollow fiber membrane strips that are not involved in the filtration process, preventing air suction and ensuring that the micropores on the surface of the hollow fiber membrane strips are not crushed, closed, or irreversibly deformed. This improves the filtration efficiency of the hollow fiber membrane strips for wastewater. At the same time, the internal support provided by the cleaning tube and the sealing block ensures the relative roundness of the hollow fiber membrane strips. The circular flow channel ensures that the pressure is evenly distributed on the membrane surface, reducing the probability of membrane pore rupture and extending the service life of the hollow fiber membrane strips.

[0035] The guiding assembly 19 includes a guide post 20, a guide frame 21, a guide spring 22, a waterproof ranging sensor 23, a guide magnet 24, and a driving electromagnet 25. The guide post 20 is slidably disposed at the end of the support frame 2 away from the integrated cylinder 1. The guide frame 21 is disposed on the upper wall of the guide post 20.

The water collection cylinder 27 is located on the side of guide frame 21 away from guide column 20, and the water collection cylinder 27 is located above integrated cylinder 1. The water supply pump 28 is located on the side wall of integrated cylinder 1, and the water supply telescopic pipe 29 is connected between the water collection cylinder 27 and the drain end of the water supply pump 28; the cleaning assembly 30 includes a cleaning thin tube 31 and a sealing... The system includes a block 32, a cleaning port 33, a drain trough 34, a drain expansion pipe 35, a cleaning check valve 36, and a sealing rubber sleeve 37. Multiple sets of the sealing rubber sleeves 37 penetrate the integrated cylinder 1 and are connected to the upper wall of the fixed cylinder 13 located at the top of the integrated cylinder 1. Multiple sets of cleaning capillary tubes 31 are connected to the bottom wall of the water collection cylinder 27. The end of the cleaning capillary tube 31 furthest from the water collection cylinder 27 penetrates the sealing rubber sleeve 37 and is located inside the hollow fiber membrane strip 14. The outer diameter of the cleaning capillary tube 31 is larger than the inner diameter of the sealing rubber sleeve 37 but smaller than the inner diameter of the hollow fiber membrane strip 14. The rubber sleeve 37 fits tightly against the outer surface of the cleaning capillary tube 31 through its own deformation. The cleaning port 33 is located at the end of the cleaning capillary tube 31 away from the water collection cylinder 27. The sealing block 32 is located on the bottom wall of the cleaning capillary tube 31. The outer diameter of the sealing block 32 is the same as the inner diameter of the hollow fiber membrane strip 14. The drain trough 34 is located on the upper wall of the pressure plate 9. The drain trough 34 is open at the top. The drain expansion pipe 35 passes through the integrated cylinder 1 and is connected to the bottom wall of the drain trough 34. The cleaning one-way valve 36 is connected to the end of the drain expansion pipe 35 away from the drain trough 34.

[0036] The integrated cylinder 1 is equipped with a controller 38 on its side wall.

[0037] The controller 38 is electrically connected to the water pump 15, the waterproof distance sensor 23, the drive electromagnet 25, and the water supply pump 28, respectively.

[0038] In practical use, the sewage pipe is connected to the inlet valve 6. Sewage enters the annular pipe 5 through the inlet valve 6. The sewage inside the annular pipe 5 is discharged into the integrated cylinder 1 below the pressure plate 9 through the filter pipe 7. The cleaning tube 31 is located inside the hollow fiber membrane strip 14. The bottom wall of the sealing block 32 is flush with the bottom wall of the pressure plate 9. The sealing block 32 blocks the hollow fiber membrane strip 14 above the pressure plate 9, so that the water pump 15 can only pump the hollow fiber membrane strip 14 below the pressure plate 9.

[0039] When a large amount of sewage enters the bottom of the integrated cylinder 1, the sewage squeezes the pressure plate 9. The pressure plate 9 slides and rises along the inner wall of the integrated cylinder 1 by utilizing the deformation of the pressure spring 10. The pressure plate 9 drives the water-blocking rubber sleeve 11 to slide and rise along the outer surface of the hollow fiber membrane strip 14, thereby expanding the contact area between the sewage and the hollow fiber membrane strip 14 and increasing the sewage treatment capacity.

[0040] The cutting height of the hollow fiber membrane strip 14 is adjusted according to the amount of sewage entering the integrated cylinder 1 to prevent the hollow fiber membrane strip 14 that is not submerged in sewage from being sucked in. When the amount of sewage entering the bottom of the integrated cylinder 1 increases, the pressure plate 9 rises, and the controller 38 controls the waterproof distance sensor 23 to start. As the pressure plate 9 rises, the distance between the measuring end of the waterproof distance sensor 23 and the bottom of the integrated cylinder 1 increases accordingly. At this time, the controller 38 controls the drive electromagnet 25 to start. After receiving the signal, the drive electromagnet 25 is energized to generate... The magnetic drive electromagnet 25 and the guide magnet 24 are set with the same poles. The drive electromagnet 25 is fixed at the bottom of the support frame 2 and pushes the guide magnet 24 through repulsion. The guide magnet 24 drives the guide column 20 to slide and rise along the support frame 2. The guide column 20 drives the water collection cylinder 27 to rise through the guide frame 21. The water collection cylinder 27 drives the cleaning tube 31 to drive the sealing block 32 to rise along the inner wall of the hollow fiber membrane strip 14, so that the bottom wall of the sealing block 32 always remains flush with the bottom wall of the pressure plate 9, avoiding the phenomenon of air suction in the hollow fiber membrane strip 14.

[0041] The controller 38 controls the water pump 15 to start. The water pump 15 draws sewage from inside the integrated cylinder 1 through the hollow fiber membrane strip 14. After being filtered by the hollow fiber membrane strip 14, the sewage enters the fixed cylinder 13 at the bottom of the integrated cylinder 1. The clean water filtered inside the fixed cylinder 13 flows into the water pumping pipe 16 and is discharged through the drain valve 17. The drain valve 17 is connected to the filtered water pipe.

[0042] When the amount of sewage entering the integrated cylinder 1 decreases, the pressure plate 9 uses the deformation of the pressure spring 10 to contact the sewage surface. The controller 38 controls the water supply pump 28 to start. The water supply pump 28's pumping end is connected to the clean water pipeline. The water supply pump 28 delivers cleaning water into the water collection cylinder 27 through the water supply expansion pipe 29. The cleaning water inside the water collection cylinder 27 enters the interior of the filtered hollow fiber membrane strip 14 through the cleaning thin pipe 31 and the cleaning port 33. The cleaning water backwashes the hollow fiber membrane strip 14 from the inside out, removing the pollutants adsorbed on the outer surface of the hollow fiber membrane strip 14. The water containing impurities flows into the drain expansion pipe 35 through the drain tank 34 and is then discharged through the cleaning check valve 36. The cleaning check valve 36 is connected to the sewage pipeline, completing the cleaning operation of the hollow fiber membrane strip 14 and ensuring the filtration efficiency of the hollow fiber membrane strip 14 for sewage. The above operation can be repeated for the next use.

[0044] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
