Description

Technical Field

[0001] This utility model relates to the field of membrane separation technology, and in particular to an aerated external pressure willow-type hollow tube membrane filter. Background Technology

[0002] Hollow tubular membrane filters typically consist of multiple hollow tubular membranes, which have closed and open ends. During use, the liquid medium flows from the outside to the inside and is filtered through the tiny pores of the hollow tubular membrane. Due to the small pore size of the hollow tubular membrane, it can effectively trap suspended solids, particulate matter, bacteria and other impurities, thereby purifying the liquid.

[0003] Common hollow fiber membrane filters lack self-cleaning capabilities. As more and more dirt accumulates on the surface of the hollow fiber membrane, the filtration effect deteriorates. To address these issues, Chinese patent CN201147676Y discloses an aerated external pressure willow-type hollow fiber membrane or capillary membrane filter. In this filter, the top of the hollow fiber membrane or capillary membrane is cast together with the top liquid-collecting chamber. The inner cavity of the hollow fiber membrane or capillary membrane is connected to the inner cavity of the top liquid-collecting chamber and the liquid collection pipe of the top liquid-collecting chamber. The upper ends of the hollow fiber membrane or capillary membrane are sealed and relatively open. The hollow fiber membrane or capillary membrane is placed inside the outer shell. The bottom of the outer shell is connected to the bottom liquid-collecting chamber, which has an inlet pipe and an air inlet pipe. The air inlet pipe is connected to an aeration device located in the bottom liquid-collecting chamber. The aeration device continuously or intermittently aerates upwards from the bottom of the filter. The top of the outer shell has a gas-liquid outlet. Under pressure, the filtered liquid permeates through the hollow fiber membrane or capillary membrane wall into the top liquid-collecting chamber, and then enters the liquid collection pipe within the liquid-collecting chamber.

[0004] The hollow tubular membrane in this device cannot be disassembled, making it difficult to replace during use. This negatively impacts the overall lifespan of the filter. Over time, the surface of the hollow tubular membrane is prone to damage, further reducing its filtration efficiency and ultimately shortening the effective working time of the entire filter.

[0010] As a further description of the above technical solution:

[0011] A load-bearing block is fixedly connected to one end of the sewage pipe, and a rubber pad is fixedly connected to one side of the outer wall of the load-bearing block. Multiple sets of inserts pass through the rubber pad.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) By setting hollow tubular membranes, these membrane materials have a high surface area and good water permeability, which can maximize the use of the effective area of ​​the membrane during the filtration process. By setting a connection structure between multiple sets of first threaded rods and threaded caps, multiple sets of crossbars can be fixed on the insertion plate.

[0022] (2) By setting up an aeration device, bubbles can be generated periodically or continuously. The impact of the bubbles is used to backwash the membrane, effectively removing dirt and contaminants attached to the membrane surface. This backwashing method does not require stopping work, avoiding production interruptions caused by frequent shutdowns in traditional cleaning methods, and improving work efficiency. The external pressure of the aeration external pressure willow membrane pushes the liquid through the membrane material to complete the liquid separation process. Due to the use of external pressure drive, it can achieve high flow rate and high separation efficiency at a lower operating pressure, which is particularly suitable for treating liquids with high turbidity and high particulate matter. In the membrane design, an optimized willow structure is adopted, which makes the bubbles generate a more uniform impact effect when moving on the membrane surface, improving backwashing efficiency and reducing contaminant deposition on the membrane surface. By setting up multiple monitoring modules, the internal condition of the shell can be monitored in real time from multiple angles. By setting up a wireless signal transmitter, the monitored data can be transmitted in the form of a signal. By setting up a wireless signal receiver, the monitored data can be received and then displayed in real time on the display control panel. The staff can monitor the working status and membrane fouling level in real time, automatically adjust the cleaning cycle, and ensure long-term stable operation. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0030] Reference Figure 1-2 This utility model provides an embodiment of an aerated external pressure willow-type hollow tube membrane filter, including a shell 1. A water inlet pipe 2 passes through the bottom of one side of the outer wall of the shell 1, and a sewage discharge pipe 3 passes through the top of one side of the outer wall of the shell 1. By setting the sewage discharge pipe 3, it can be used to discharge dirt and gas. A solenoid valve 4 is installed at the outlet of the sewage discharge pipe 3. An aeration device 10 is fixedly connected to the bottom of the inner wall of the shell 1. An air inlet pipe 11 is fixedly connected to the bottom of the aeration device 10. Multiple sets of nozzles 12 are fixedly connected to the top of the aeration device 10. A load-bearing block 13 is fixedly connected to one end of the top of the sewage discharge pipe 3. A rubber pad 14 is fixedly connected to one side of the outer wall of the load-bearing block 13. Multiple sets of inserts 16 pass through the rubber pad 14. A water outlet pipe 19 passes through one end of the top of the shell 1. By setting the water outlet pipe 19, the treated water source can be discharged.

[0031] A frame 20 extends through the top of the other outer wall of the outer casing 1. A sealing plate 21 is fitted onto the inner wall of the frame 20. A side plate 22 is fixedly connected to one side of the outer wall of the sealing plate 21. The same end of the sealing plate 21 and the side plate 22 extends through the casing 23. A socket plate 24 is fixedly connected to one end of the inner wall of the casing 23. The socket plate 24 has multiple sets of square sockets, and a block 25 is inserted into the inner wall of each square socket. A first threaded rod 26 is fixedly connected to the center of one side of the outer wall of each block 25. A threaded cap 27 is threadedly connected to the outer wall of each first threaded rod 26. A crossbar 17 is fixedly connected to the other outer wall of block 25. A sleeve hole 18 is opened at the center of the outer wall of one side of the crossbar 17. The outer wall of the insertion tube 16 is sleeved with the inner wall of the sleeve hole 18. The outer wall of one side of the crossbar 17 is in close contact with the opposite side of the rubber pad 14. Multiple sets of through holes are opened in the crossbar 17. A rubber ring 8 is sleeved on the inner wall of each hole. A hollow tubular membrane 15 is fixedly connected to the inner wall of each rubber ring 8. A threaded tube 9 is fixedly connected to the outer edge of the top of the hollow tubular membrane 15. A threaded ring 28 is threadedly connected to the outer wall of each threaded tube 9.

[0032] Rubber sheets 29 are fixedly connected to both the front and rear ends of the crossbar 17. It is worth noting that the opposite faces of two adjacent sets of rubber sheets 29 are tightly pressed together, and the opposite faces of the two sets of rubber sheets 29 at the front and rearmost points are tightly pressed against the inner walls of the outer casing 1. Through the mutual contact of multiple sets of crossbars 17 and rubber sheets 29, a closed isolation structure can be formed, thus dividing the interior of the outer casing 1 into two chambers. At this time, the area above the crossbar 17 is the water production chamber, and the area below the crossbar 17 is the water filtration chamber. By setting up a connection structure between multiple sets of first threaded rods 26 and threaded caps 27, multiple sets of crossbars 17 can be fixed to the insertion plate 24. (Hollow) The tubular membrane 15 is configured as a columnar structure with an opening at the top. Water enters the interior of the hollow tubular membrane 15 through the outer wall, while dirt and contaminants remain on the outside. Clean water enters the interior and flows through the threaded pipe 9 into the product water chamber above the crossbar 17, before being discharged through the outlet pipe 19. By using the hollow tubular membrane 15, these membrane materials have a high surface area and good permeability, maximizing the effective area of ​​the membrane during filtration. The aeration device 10 allows for periodic or continuous aeration. Continuous bubble generation and the impact of these bubbles perform backwashing of the membrane, effectively removing dirt and contaminants adhering to the membrane surface. This backwashing method does not require shutdown, avoiding production interruptions caused by frequent downtime in traditional cleaning methods, thus improving work efficiency. The external pressure of the aerated willow-type membrane forces the liquid through the membrane material, completing the liquid separation process. Due to the external pressure drive, high flow rates and high separation efficiency can be achieved at lower operating pressures, making it particularly suitable for treating liquids with high turbidity and high particulate matter content. The membrane design incorporates an optimized willow-type structure, enabling… When the bubbles move on the membrane surface, they can generate a more uniform impact effect, improve backwashing efficiency and reduce contaminant deposition on the membrane surface. The outer walls of one side of the frame 20 are fixedly connected to two ends of the second threaded rod 31. The outer walls of the second threaded rod 31 penetrate through both ends of the side plate 22 and extend out. The extended ends of the second threaded rod 31 are threadedly connected to nuts 32. By setting the connection structure between the second threaded rod 31 and the nuts 32, the sealing plate 21 can be fixed in the frame 20. By setting the connection structure between the threaded tube 9 and the threaded ring 28, it is convenient for staff to replace the damaged hollow tubular membrane 15 individually.

[0033] Monitoring modules 5 are installed at the center of one side outer wall, the rear end, and the top center of the outer casing 1. A wireless signal transmitter 6 is fixedly connected to the end of each monitoring module 5. A display control panel 7 is fixedly connected to the front end of the outer casing 1, and a wireless signal receiver 30 is fixedly connected to the top of the display control panel 7. By setting up multiple monitoring modules 5, the internal conditions of the outer casing 1 can be monitored in real time from multiple angles. By setting up the wireless signal transmitter 6, the monitored data can be transmitted in the form of signals. By setting up the wireless signal receiver 30, the monitored data can be received and then displayed in real time on the display control panel 7.
