Description

Technical Field

[0001] This utility model relates to the field of MBR membrane module technology, specifically to a dirt-resistant and easily disassembled MBR membrane module. Background Technology

[0002] MBR membrane modules are the core components of membrane bioreactor systems. They combine biological treatment (such as the activated sludge process) with membrane separation technology and are mainly used in wastewater treatment and wastewater reuse processes. The main function of MBR membrane modules is to achieve efficient solid-liquid separation. Their working principle is that in the bioreactor, microorganisms biodegrade organic matter in the wastewater, while the membrane module acts as a filter medium, retaining activated sludge and most suspended solids in the water, allowing only clear water molecules to pass through, thereby achieving water purification.

[0003] In existing MBR membrane modules, multiple membrane sheets are slid into the support frame during assembly. A baffle is then installed on one side of the support frame to position the membrane sheets and prevent them from moving. However, the baffles are fixed to the top and bottom of the support frame with bolts, which is inconvenient for assembling and disassembling the MBR membrane module. At the same time, during the wastewater filtration process, the MBR membrane module is inside the wastewater tank. Over a long period of filtration, a large amount of solid matter will be adsorbed on the surface of the membrane fibers. The cleaning effect of the aeration pipes installed at the bottom of the support frame on the surface of the membrane fibers in the MBR membrane module is poor. Utility Model Content

[0004] The purpose of this invention is to provide a dirt-resistant and easily detachable MBR membrane module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fouling-resistant and easily detachable MBR membrane module, including a membrane module support. The membrane module support has a flow channel inside its pipe for water circulation. Limiting blocks are fixedly installed at equal intervals at the top and bottom of the membrane module support. A membrane assembly is slidably installed between two limiting blocks on the same vertical plane. L-shaped fixing blocks are fixedly installed at both ends of one side of the membrane module support. Two L-shaped fixing blocks on the same side are arranged one above the other. A baffle is detachably installed between the two L-shaped fixing blocks at the same height and the membrane module support. A rotating shaft is rotatably installed at equal intervals on the top of the membrane module support via bearings. The rotating shaft is positioned between two membrane assemblies. Plastic flexible strips are fixedly installed at equal intervals on the outer side of the bottom end of the rotating shaft, and the plastic flexible strips are positioned at the membrane strip position of the membrane assembly.

[0006] As a further preferred embodiment of this technical solution, a sliding hole is provided in the middle of the L-shaped fixing block, and a positioning rod is slidably installed inside the sliding hole. Positioning holes are provided at both ends of the baffle, and the positioning rod is slidably inserted into the positioning hole. A return spring is sleeved on the outer side of one end of the positioning rod, one end of the return spring is fixedly connected to one end of the positioning rod, and the other end of the return spring is fixedly connected to the outer side of the L-shaped fixing block.

[0007] As a further preferred embodiment of this technical solution, the end of the positioning rod away from the reset spring is provided with a first chamfer, and the bottom corner of the baffle is provided with a second chamfer.

[0008] As a further preferred embodiment of this technical solution, a first gear is fixedly installed on the outer side of the top end of the rotating shaft, and the two first gears on two adjacent rotating shafts are meshed together.

[0009] As a further preferred embodiment of this technical solution, a drain pipe is fixedly installed on the top of the membrane module support, and the drain pipe is connected to the flow channel inside the membrane module support. A rotating rod is rotatably installed at the top of the membrane module support inside the drain pipe via a mechanical seal. A blade is fixedly installed at the top of the rotating rod, and a second gear is fixedly installed at the bottom of the rotating rod. The second gear meshes with a first gear on one of the rotating shafts.

[0010] As a further preferred embodiment of this technical solution, connecting pipes are fixedly installed at equal intervals on one side of the top of the membrane module support. The connecting pipes are connected to the flow channels inside the membrane module support. A U-shaped water pipe is connected between the water outlet end of the membrane assembly and the connecting pipe.

[0012] This invention provides a dirt-resistant and easily disassembled MBR membrane module, which has the following beneficial effects:

[0013] (1) This utility model slides the diaphragm assembly between two limiting blocks at the top and bottom of the same vertical plane, installs several diaphragm assemblies inside the diaphragm support, and then slides the baffle into the position between the L-shaped fixing block and the diaphragm support. The second chamfer on the baffle will squeeze the first chamfer at the end of the positioning rod, and control the positioning rod to slide inside the sliding hole. At this time, the return spring is in the stretched state. When the positioning rod coincides with the positioning hole, the return spring will control the positioning rod to insert into the positioning holes at both ends of the baffle, thereby fixing the position of the baffle. The baffle can position the diaphragm assemblies installed at the top and bottom of the diaphragm support, which is convenient for the installation of the diaphragm assemblies. When the diaphragm assembly is removed, the end of the positioning rod is pulled to slide the positioning rod out of the positioning hole, and the baffle can be removed from the position between the L-shaped fixing block and the diaphragm support. The diaphragm assembly can be removed without the need to use bolts to install and remove the baffle, which is convenient for the installation and removal of the diaphragm assembly.

[0014] (2) The water filtered by the membrane strips on the membrane assembly will be discharged from the drain pipe through the U-shaped water pipe, the connecting pipe and the flow channel inside the membrane assembly support. The water will push the blades and drive them to rotate, thereby realizing the rotation of the rotating rod. At the same time, the second gear is controlled to rotate. The meshing of the second gear with the first gear on one of the rotating shafts and the meshing between the two first gears on two adjacent rotating shafts will drive several rotating shafts to rotate synchronously. The plastic flexible strips on the rotating shafts can hit the membrane strips on the membrane assembly, which can clean the impurities adsorbed on the membrane strips on the membrane assembly and improve the efficiency of the membrane assembly.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a fouling-resistant and easily detachable MBR membrane module includes a membrane support 1. The membrane support 1 has a flow channel for water circulation inside its pipes. Limiting blocks 2 are fixedly installed at equal intervals at the top and bottom of the membrane support 1. A membrane assembly 3 is slidably installed between two limiting blocks 2 on the same vertical plane. L-shaped fixing blocks 4 are fixedly installed at both ends of one side of the membrane support 1. Two L-shaped fixing blocks 4 on the same side are arranged one above the other. A baffle 5 is detachably installed between the two L-shaped fixing blocks 4 at the same height and the membrane support 1. A rotating shaft 6 is rotatably installed at the top of the membrane support 1 via bearings. The rotating shaft 6 is positioned between two membrane assemblies 3. Plastic flexible strips 7 are fixedly installed at equal intervals on the outer side of the bottom end of the rotating shaft 6. At the membrane strip position of the diaphragm assembly 3, slide the diaphragm assembly 3 between the two limiting blocks 2 at the top and bottom on the same vertical plane, install several diaphragm assemblies 3 inside the membrane group support 1, and then slide the baffle 5 into the position between the L-shaped fixing block 4 and the membrane group support 1. The baffle 5 can position the diaphragm assemblies 3 installed at the top and bottom of the membrane group support 1, which facilitates the installation of the diaphragm assembly 3. When removing the diaphragm assembly 3, the baffle 5 can be removed from the position between the L-shaped fixing block 4 and the membrane group support 1, and the diaphragm assembly 3 can be removed. During the use of this device, control several rotating shafts 6 to rotate synchronously, which can drive the plastic flexible strips 7 on the rotating shafts 6 to strike the membrane strips on the diaphragm assembly 3, which can clean the impurities adsorbed on the membrane strips on the diaphragm assembly 3 and improve the use efficiency of the diaphragm assembly 3.

[0022] like Figures 1 to 4 As shown, the L-shaped fixing block 4 has a sliding hole 8 in the middle, and a positioning rod 9 is slidably installed inside the sliding hole 8. Both ends of the baffle 5 have positioning holes 10. The positioning rod 9 is slidably inserted into the positioning hole 10. A return spring 12 is sleeved on the outer side of one end of the positioning rod 9. One end of the return spring 12 is fixedly connected to one end of the positioning rod 9. The other end of the return spring 12 is fixedly connected to the outer side of the L-shaped fixing block 4. A first chamfer 13 is provided at the end of the positioning rod 9 away from the return spring 12. A second chamfer 14 is provided at one bottom corner of the baffle 5.

[0023] Then, slide the baffle 5 into the position between the L-shaped fixing block 4 and the membrane support 1. The second chamfer 14 on the baffle 5 will press the first chamfer 13 at the end of the positioning rod 9, causing the positioning rod 9 to slide inside the sliding hole 8. At this time, the return spring 12 is in the extended state. When the positioning rod 9 coincides with the positioning hole 10, the return spring 12 will drive the positioning rod 9 to be inserted into the positioning holes 10 at both ends of the baffle 5, thereby fixing the position of the baffle 5. The baffle 5 can position the membrane assembly 3 installed at the top and bottom of the membrane support 1, which facilitates the installation of the membrane assembly 3. When removing the membrane assembly 3, pull the end of the positioning rod 9 to slide the positioning rod 9 out of the positioning hole 10. The baffle 5 can be removed from the position between the L-shaped fixing block 4 and the membrane support 1, and the membrane assembly 3 can be removed.

[0024] like Figures 1 to 4 As shown, a first gear 15 is fixedly installed on the outer side of the top end of the rotating shaft 6. The two first gears 15 on two adjacent rotating shafts 6 are meshed and connected. A drain pipe 16 is fixedly installed on the top of the membrane module support 1. The drain pipe 16 is connected to the flow channel inside the membrane module support 1. A rotating rod 17 is rotatably installed on the top of the membrane module support 1 at the position inside the drain pipe 16 through a mechanical seal. A blade 18 is fixedly installed on the top of the rotating rod 17. A second gear 19 is fixedly installed on the bottom of the rotating rod 17. The second gear 19 is meshed and connected to one of the first gears 15 on the rotating shaft 6. A connecting pipe 20 is fixedly installed at equal intervals on one side of the top of the membrane module support 1. The connecting pipe 20 is connected to the flow channel inside the membrane module support 1. A U-shaped water pipe 21 is connected between the water outlet end of the membrane assembly 3 and the connecting pipe 20.

[0025] Water filtered by the membrane strips on the membrane assembly 3 will be discharged from the drain pipe 16 through the U-shaped water pipe 21, the connecting pipe 20, and the flow channel inside the membrane support 1. The water will push the blades 18 and drive them to rotate, thereby realizing the rotation of the rotating rod 17. At the same time, it controls the rotation of the second gear 19. The meshing of the second gear 19 with the first gear 15 on one of the rotating shafts 6 and the meshing between the two first gears 15 on two adjacent rotating shafts 6 will drive several rotating shafts 6 to rotate synchronously.

[0026] like Figures 1 to 4 As shown, aeration pipes 22 are fixedly installed at equal intervals at the bottom of the membrane support 1, and aeration holes 11 are opened at equal intervals at the top of the aeration pipes 22. The aeration pipes 22 are connected to the aeration system through pipes.

[0027] Air is introduced into the aeration pipe 22 through the aeration system, and the gas will be discharged from the aeration hole 11, which can aerate and clean the impurities on the membrane strip of the membrane assembly 3.

[0028] This invention provides a dirt-resistant and easily detachable MBR membrane module, the specific working principle of which is as follows:

[0029] When the device is in use, the diaphragm assembly 3 is slid between the two limiting blocks 2 at the top and bottom on the same vertical plane. Several diaphragm assemblies 3 are installed inside the membrane support 1. Then, the baffle 5 is slid into the position between the L-shaped fixing block 4 and the membrane support 1. The second chamfer 14 on the baffle 5 will squeeze the first chamfer 13 at the end of the positioning rod 9, causing the positioning rod 9 to slide inside the sliding hole 8. At this time, the return spring 12 is in the stretched state. When the positioning rod 9 coincides with the positioning hole 10, the positioning rod 9 is inserted into the positioning holes 10 at both ends of the baffle 5 by the action of the return spring 12, thereby fixing the position of the baffle 5. The baffle 5 can position the diaphragm assemblies 3 installed at the top and bottom of the membrane support 1, which facilitates the installation of the diaphragm assemblies 3. When the diaphragm assembly 3 is removed, the end of the positioning rod 9 is pulled to slide the positioning rod 9 out of the positioning hole 10. The baffle 5 can be removed from the position between the L-shaped fixing block 4 and the membrane support 1, and the diaphragm assembly 3 can be removed.

[0030] During the use of this device, the water filtered by the membrane strips on the membrane assembly 3 will be discharged from the drain pipe 16 through the U-shaped water pipe 21, the connecting pipe 20, and the flow channel inside the membrane support 1. The water will push the blades 18, thereby causing the blades 18 to rotate, which in turn causes the rotating rod 17 to rotate. At the same time, it controls the rotation of the second gear 19. The meshing of the second gear 19 with the first gear 15 on one of the rotating shafts 6 and the meshing between the two first gears 15 on two adjacent rotating shafts 6 will drive several rotating shafts 6 to rotate synchronously. This will cause the plastic flexible strips 7 on the rotating shafts 6 to strike the membrane strips on the membrane assembly 3, thereby cleaning the impurities adsorbed on the membrane strips on the membrane assembly 3 and improving the utilization efficiency of the membrane assembly 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
