Description

Technical Field

[0001] This utility model relates to the field of MBR membrane module technology, specifically to an MBR membrane module for wastewater treatment that is easy to clean. Background Technology

[0002] With increasing attention to environmental protection, wastewater generated in daily life and production is treated before being discharged. MBR membranes are one way to treat wastewater. An MBR membrane is a microporous filter membrane with a uniform pore size and a rated pore size range of 0.001-0.15 micrometers. By applying appropriate pressure to one side of the membrane, solute molecules smaller than the pore size can be screened out. MBR membrane modules are usually installed at the bottom of the wastewater treatment tank.

[0003] For example, Chinese patent application CN209940591 U discloses an MBR membrane module suitable for micro-sewage treatment devices, which includes an MBR membrane sheet and a frame. A plurality of MBR membrane sheets are internally connected within the frame. Each MBR membrane sheet has an outlet at its top and an aeration hole at its bottom. An air inlet pipe and an outlet pipe are connected to the top of the frame. The frame is a cubic frame composed of a plurality of hollow connecting rods. This technical solution adds aeration holes to the lower end of the MBR membrane sheet. The hollow structure of the supporting rods forming the frame not only supports the MBR membrane sheet as part of the frame but also serves as a water collection pipe and an air inlet pipe. This eliminates the need for separate water collection pipes, aeration pipes, and air inlet pipes, reducing manufacturing costs and space usage. The structure is simple and easy to use.

[0004] However, the following problems still exist in this technical solution: the MBR membrane is installed inside the frame and cannot be removed from the frame, thus making it impossible to clean the MBR membrane, which has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide an MBR membrane module for wastewater treatment that is easy to clean. The MBR membrane can be removed from the support frame through the installation mechanism, making it convenient for workers to clean the MBR membrane. The support frame can also be installed at the bottom of the wastewater treatment tank through the support mechanism, which is convenient to use and improves the stability of the support frame, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-clean MBR membrane module for wastewater treatment, including a support frame, a plurality of MBR membranes inside the support frame, a first connecting pipe on one side of the support frame, an inlet pipe fixedly connected to the top of the first connecting pipe, a plurality of second connecting pipes connected to one side of the first connecting pipe, one end of the second connecting pipe extending into the support frame, one top end of the MBR membrane being able to be inserted into the second connecting pipe, an aeration pipe on one side of the bottom of the support frame, one end of the aeration pipe extending into the support frame, and a plurality of aeration holes opened on the aeration pipe;

[0007] Preferably, the support frame is provided with an installation mechanism for installing and removing multiple MBR membranes. The installation mechanism includes two first support plates at the bottom of the support frame and two second support plates at the top of the support frame. Two installation slots are provided on both sides of the top of the support frame. The same second support plate can be inserted into the two installation slots on the same side. Multiple first placement slots are provided on both the first and second support plates. The first placement slots are adapted to the MBR membranes. Multiple second placement slots are provided on the first support plates. The second placement slots are adapted to the aeration holes for installing and removing multiple MBR membranes.

[0008] Preferably, each of the mounting slots has a first threaded hole inside, and the second support plate has second threaded holes on both sides. The first threaded hole and the second threaded hole are connected by the same first bolt for fixing the second support plate.

[0009] Preferably, one end of the second connecting tube is provided with a sealing mechanism for sealing the connection between the MBR membrane and the second connecting tube. The sealing mechanism includes a sealing ring at one top end of the MBR membrane. The second connecting tube is adapted to the sealing ring. The sealing ring has two fourth threaded holes, and the second connecting tube has two third threaded holes. The third threaded holes and the fourth threaded holes are connected internally to the same second bolt for sealing the connection between the MBR membrane and the second connecting tube.

[0010] Preferably, the support frame is externally provided with a support mechanism for installing the support frame. The support mechanism includes multiple threaded cylinders on both sides of the support frame. Both ends of the threaded cylinders pass through the support frame and are movably connected to the support frame via bearings. A threaded rod is threadedly connected inside the threaded cylinder. A fixing plate is fixedly provided at the end of the threaded rod away from the support frame. Multiple rubber granules are fixedly provided on the fixing plate. A telescopic rod is fixedly provided on one side of the fixing plate. One end of the telescopic rod passes through the support frame and is fixedly connected to the support frame. A handle is fixedly provided at one end of the threaded cylinder for installing the support frame.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] 1. When the MBR membrane needs to be disassembled, turn the first bolt to turn it out of the second threaded hole and the inside of the first threaded hole. Then take the second support plate and remove it from the top of the support frame. Then pull the MBR membrane to remove it from the inside of the support frame, making it easier for the staff to clean the MBR membrane.

[0013] 2. Place the support frame at the bottom of the sewage treatment tank, then turn the handle. The handle will drive the threaded cylinder to rotate, which in turn drives the threaded rod to move. The movement of the threaded rod will then drive the fixed plate to move until it contacts the inner wall of the sewage treatment tank. The fixed plate will then support the support frame. The support mechanism allows the support frame to be installed at the bottom of the sewage treatment tank, making it easy to use and improving the stability of the support frame.

[0027] This utility model provides, for example Figure 1-5 The present invention relates to an easy-to-clean MBR membrane module for wastewater treatment, comprising a support frame 1, wherein a plurality of MBR membrane sheets 2 are disposed inside the support frame 1, a first connecting pipe 6 is provided on one side of the support frame 1, an inlet pipe 7 is fixedly connected to the top of the first connecting pipe 6, a plurality of second connecting pipes 8 are connected to one side of the first connecting pipe 6, one end of the second connecting pipe 8 extends into the interior of the support frame 1, and one top end of the MBR membrane sheet 2 can be inserted into the interior of the second connecting pipe 8, and an aeration pipe 9 is provided on one side of the bottom of the support frame 1, one end of the aeration pipe 9 extends into the interior of the support frame 1, and a plurality of aeration holes 10 are provided on the aeration pipe 9;

[0028] After biological treatment, the mixed liquor enters the MBR membrane 2 through the first connecting pipe 6 for filtration. The membrane pore size on the MBR membrane 2 is usually between 0.01 and 0.4 micrometers, which can effectively intercept suspended solids, bacteria and some viruses. The MBR membrane 2 separates the clean water from the sludge. The clean water is discharged through the membrane pores on the MBR membrane 2, while the sludge is returned to the bioreactor to continue degrading organic matter.

[0029] like Figure 4 As shown, the support frame 1 is equipped with an installation mechanism 3 for installing and removing multiple MBR membranes 2. The installation mechanism 3 includes two first support plates 301 at the bottom of the support frame 1 and two second support plates 302 at the top of the support frame 1. Two installation slots 303 are opened on both sides of the top of the support frame 1. The same second support plate 302 can be inserted into the two installation slots 303 on the same side. Multiple first placement slots 307 are opened on the first support plate 301 and the second support plate 302. The first placement slots 307 are adapted to the MBR membranes 2. Multiple second placement slots 11 are opened on the first support plate 301. The second placement slots 11 are adapted to the aeration holes 10. A first threaded hole 304 is opened inside each installation slot 303. Second threaded holes 305 are opened on both sides of the second support plate 302. The first threaded hole 304 and the second threaded hole 305 are connected by the same first bolt 306.

[0030] like Figure 5 As shown, one end of the second connecting pipe 8 is provided with a sealing mechanism 5 for sealing the connection between the MBR membrane 2 and the second connecting pipe 8. The sealing mechanism 5 includes a sealing ring 501 located at one top end of the MBR membrane 2. The second connecting pipe 8 is adapted to the sealing ring 501. The sealing ring 501 has two fourth threaded holes 503 and the second connecting pipe 8 has two third threaded holes 502. The third threaded holes 502 and the fourth threaded holes 503 are connected internally by the same second bolt 504.

[0031] Place the bottom of the MBR membrane 2 inside the first placement groove 307 on the first support plate 301, then insert one end of the MBR membrane 2 into the second connecting pipe 8, and then insert the sealing ring 501 into the outside of the second connecting pipe 8. Rotate the second bolt 504 to turn the second bolt 504 into the third threaded hole 502 and the sealing ring 501. Use the second bolt 504 to fix the sealing ring 501 to the outside of the second connecting pipe 8. The second bolt 504 can seal the connection between the MBR membrane 2 and the second connecting pipe 8 to prevent water leakage.

[0032] like Figure 3 As shown, the support frame 1 is provided with a support mechanism 4 for mounting the support frame 1. The support mechanism 4 includes a plurality of threaded cylinders 401 on both sides of the support frame 1. Both ends of the threaded cylinders 401 pass through the support frame 1 and are movably connected to the support frame 1 through bearings. A threaded rod 402 is threadedly connected inside the threaded cylinder 401. A fixing plate 403 is fixedly provided at the end of the threaded rod 402 away from the support frame 1. A plurality of rubber particles 406 are fixedly provided on the fixing plate 403. A telescopic rod 405 is fixedly provided on one side of the fixing plate 403. One end of the telescopic rod 405 passes through the support frame 1 and is fixedly connected to the support frame 1. A handle 404 is fixedly provided at one end of the threaded cylinder 401.

[0033] Next, place the support frame 1 at the bottom of the sewage treatment tank, and then turn the handle 404. The handle 404 can drive the threaded cylinder 401 to rotate. The rotation of the threaded cylinder 401 drives the threaded rod 402 to move. The movement of the threaded rod 402 drives the fixed plate 403 to move, moving the fixed plate 403 to contact the inner wall of the sewage treatment tank. While the fixed plate 403 is moving, it can drive the telescopic rod 405 to extend and retract. The telescopic rod 405 can limit the fixed plate 403 to prevent it from shifting. The rubber particles 406 on one side of the fixed plate 403 can increase the friction, thereby improving the stability of the support frame 1. The fixed plate 403 supports the support frame 1. The support mechanism 4 can install the support frame 1 at the bottom of the sewage treatment tank, which is convenient to use and improves the stability of the support frame 1.

[0034] To prevent contamination of the MBR membrane 2, it is necessary to perform physical or chemical cleaning on the MBR membrane 2 regularly to restore its flux. When disassembling the MBR membrane 2, rotate the first bolt 306 to unscrew it from the second threaded hole 305 and the first threaded hole 304. Then, remove the second support plate 302 from the top of the support frame 1. Finally, pull the MBR membrane 2 to remove it from the support frame 1, making it easier for staff to clean the MBR membrane 2.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
