Description

Technical Field

[0001] This utility model relates to the field of filter membrane technology for sewage treatment, and in particular to a filter membrane for sewage treatment. Background Technology

[0002] With increasingly stringent environmental regulations and ever-improving requirements for water quality, membrane filtration technology is playing an increasingly important role in wastewater treatment. Publication No. CN217312780U discloses a clean medical membrane filtration module, relating to the field of membrane filtration technology. This utility model discloses a clean medical membrane filtration module, including a membrane shell with end caps fixed at both ends of the shell. The membrane shell contains a filter element, which includes a central tube and ultrafiltration membrane fibers. Ultrafiltration membrane caps are fixed at the ends of the ultrafiltration membrane fibers. The ultrafiltration membrane caps are divided into an ultrafiltration inlet cap and an ultrafiltration outlet cap. The ultrafiltration inlet cap has a through-hole in the center for the central tube to pass through, and the ultrafiltration outlet cap has a water outlet column in the center, which is connected to the open end of the ultrafiltration membrane fibers. A concentrate outlet is provided on the circumferential surface of the membrane shell, and the concentrate outlet is flush with the ultrafiltration membrane cap. The membrane shell, end caps, central tube, and ultrafiltration membrane cap are all made of transparent polysulfone (PS) material. This invention features a transparent structure for the membrane housing, end caps, central tube, and ultrafiltration membrane cap, allowing users to easily observe the internal condition of the membrane housing and replace the ultrafiltration membrane promptly. The interior of the membrane housing has no dead corners, preventing water accumulation and bacterial growth, and facilitating cleaning. However, this solution involves complex and time-consuming membrane replacement, and requires highly skilled operators, impacting practical application and necessitating improvement.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] Please see Figure 1-6This utility model provides a technical solution: a filter membrane for sewage treatment, including a base plate 1, a sealing groove 2 on the surface of the base plate 1, a first mounting groove 3 inside the base plate 1, a first fixing plate 4 fixedly mounted on the surface of the first mounting groove 3 for supporting a fixing block 6, a limiting rod 5 slidably connected inside the first fixing plate 4 for positioning the movement of the fixing block 6, a fixing block 6 fixedly mounted at one end of the limiting rod 5, a spring 7 fixedly mounted on the surface of the fixing block 6 for facilitating the reset of the fixing block 6, a handle 8 fixedly mounted at one end of the limiting rod 5 for pulling the limiting rod 5, a filter membrane 9 placed above the base plate 1, an upper pressure plate 10 placed above the filter membrane 9, a sealing plate 11 fixedly mounted on the surface of the upper pressure plate 10, which interlocks with the sealing groove 2 to achieve good sealing performance, and the surface of the sealing plate 11... The surface of the base plate 1 has a fixing groove 12, which is interlocked with the fixing block 6 to fix it. The surface of the base plate 1 has a groove 13, and the surface of the slider 20 has a protrusion 14. The filter membrane 9 placed between the groove 13 and the protrusion 14 can be clamped by the close proximity between them. The fixing groove 12 is slidably connected to the fixing block 6, and the sealing groove 2 is slidably connected to the sealing plate 11. Each of them is interlocked, providing good sealing performance and stability. The filter membrane 9 is made of polyethersulfone (PES). Polyethersulfone (PES) has good flexibility and hydrophilicity, which can effectively filter small particles and solutes, improve the overall filtration selectivity and throughput. The spring 7 is fixedly installed between the first fixing plate 4. The elasticity of the spring 7 and the cooperation of the limiting rod 5 can keep the fixing block 6 stable during the reset process.

[0027] Example 2

[0028] Please see Figure 6-7 The upper pressure plate 10 has a second mounting groove 15 on its surface to support the mounting plate 16. The mounting plate 16 is fixedly mounted on the surface of the second mounting groove 15 to support the bolt 17. The bolt 17 is rotatably connected to the inside of the mounting plate 16 through a bearing, which facilitates the rotation of the bolt 17. A limit ring 18 is fixedly mounted on the surface of the bolt 17 to position the bolt 17. A second fixing plate 19 is threadedly connected to the surface of the bolt 17. A slider 20 is fixedly mounted on the surface of the second fixing plate 19. By rotating the bolt 17, the slider 20 can move up and down to adapt to the height of the stacked filter membranes 9. The limit ring 18 is rotatably connected to the mounting plate 16, and the slider 20 is slidably connected to the upper pressure plate 10 to keep it stable when moving up and down. The slider 20 is fixedly mounted to the protrusion 14. The protrusion 14, in conjunction with the groove 13, can effectively clamp the filter membrane 9.

[0029] Working principle: When the filter membrane 9 needs to be removed, first, position the upper pressure plate 10 facing the ground for easy removal of the filter membrane 9. Then, pull the handle 8 to move the limiting rod 5, causing the fixing block 6 to slide out of the fixing groove 12 and release its fixing effect on the upper pressure plate 10. After that, hold the handle 8 and lift upwards to separate the base plate 1 from the upper pressure plate 10. Finally, remove the filter membrane 9. When the filter membrane 9 needs to be installed, first place the filter membrane 9 on the groove 13 of the base plate 1. Then, stack the filter membranes 9 as needed to achieve a better filtration effect. After stacking, align the sealing plate 11 with the sealing groove 2 and insert it. At the same time, the edge of the sealing plate 11 will touch the inclined surface of the fixing block 6. When the sealing plate 11... 1. When the pressure continues, it will descend along the slope, causing the fixing block 6 to slide back inside the first mounting groove 3. When it reaches a certain position, the fixing block 6 will slide into the fixing groove 12 opened on the sealing plate 11 under the action of the spring 7, thereby completing the fixing of the upper pressure plate 10. Then, by turning the bolt 17 with a tool, the second fixing plate 19 will drive the slider 20 to descend. The protrusion 14 installed on the slider 20 will press down on the filter membrane 9. Since the filter membrane 9 has good flexibility and elasticity, when the slider 20 continues to descend, the part of the filter membrane 9 pressed by the protrusion 14 will cause the bottom surface of the filter membrane 9 to bulge slightly, so that it contacts the groove 13, thereby completing the clamping effect of the filter membrane 9.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
