[0002] The membrane bioreactor is a new, highly efficient water treatment system that combines membrane separation technology with biological treatment technology. It combines a membrane separation unit with a biological treatment unit, achieving advanced wastewater treatment through the efficient separation effect of the membrane and the degradation effect of microorganisms in the biological treatment unit.

[0003] When the membrane of a membrane bioreactor becomes heavily contaminated, offline cleaning is necessary. In this case, the membrane must be disassembled for cleaning. However, conventional membranes currently on the market are often mounted on membrane bioreactors using numerous bolts and glue, making it difficult to disassemble and clean the membrane. Therefore, a membrane bioreactor that facilitates membrane disassembly and cleaning is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6A membrane bioreactor that is easy to clean includes a membrane bioreactor body 1 and a membrane assembly 2. The membrane assembly 2 is provided with mounting rods 21 on both the upper and lower sides. The membrane assembly 2 is mounted on the membrane bioreactor body 1 via the mounting rods 21. A fixing plate 3 is fixedly provided on the membrane bioreactor body 1 corresponding to the mounting rods 21. A removable movable plate 4 is mounted above the fixing plate 3. Plug-ins 42 are fixedly provided on both sides of the bottom of the movable plate 4. Receptacles 32 are provided on the fixing plate 3 corresponding to the plug-ins 42.

[0022] The principle of a membrane bioreactor is to utilize microorganisms within the bioreactor to degrade organic matter in water. Subsequently, membrane separation technology is used to trap the microorganisms, suspended solids, and macromolecular substances on one side of the membrane, while clear water passes through the membrane to the other side, achieving solid-liquid separation and water purification. It is worth noting that the specific structure and operating methods of the membrane bioreactor 1 and membrane assembly 2 are prior art and therefore will not be described in detail.

[0023] The fixed plate 3 is connected to one side of the insertion hole 32 and is provided with a movable cavity 33. A limit post 5 is provided in the movable cavity 33 and is movable by a spring 51. A spring 51 is provided at one end of the movable cavity 33, and the other end of the spring 51 is connected to the limit post 5. The elastic force of the spring 51 can push the limit post 5 out.

[0024] The insert 42 has a limit cavity 43 corresponding to the limit column 5, and an adjustment rod 52 is fixed to the top of the limit column 5. An adjustment cavity 34 is also defined on the fixed plate 3, corresponding to the adjustment rod 52, above the movable cavity 33. The adjustment rod 52 extends from the adjustment cavity 34 and is fixedly connected to an adjustment handle 53. Turning the adjustment handle 53 moves the adjustment rod 52, thereby moving the limit column 5.

[0025] Among them, the bottom of the movable plate 4 is fixedly provided with a plurality of positioning posts 41, and the corresponding positioning posts 41 on the fixed plate 3 are adapted to have positioning holes 31. Through the adaptation between the positioning posts 41 and the positioning holes 31, the movable plate 4 can be positioned when it is installed.

[0026] Among them, the fixed plate 3 and the movable plate 4 are respectively provided with mounting grooves 6, and the mounting grooves 6 are adapted to the ends of the mounting rods 21. By clamping the ends of the mounting rods 21 in the mounting grooves 6, the mounting rods 21 can be installed.

[0027] In this embodiment, when the membrane assembly 2 on the membrane bioreactor body 1 needs to be disassembled and cleaned, the user only needs to pull the adjustment handles 53 on both sides of the fixed plate 3 outward to release the locking between the limit posts 5 and the limit cavities 43. The user can then directly move the movable plate 4 upward to remove it, thereby completing the disassembly and cleaning of the membrane assembly 2.

[0028] Furthermore, after the user has finished cleaning the diaphragm assembly 2 , he or she only needs to place the mounting rods 21 on both sides of the diaphragm assembly 2 into the positioning holes 31 on the fixed plate 3 , and then install the movable plate 4 above the fixed plate 3 .

[0029] It is worth noting that when the user is installing the movable plate 4, it is necessary to pull the adjustment handles 53 on both sides of the fixed plate 3 outward, so that the adjustment handles 53 can drive the adjustment rod 52 and the limit column 5 to move into the movable cavity 33, and the spring 51 is compressed. At this time, the user can insert the plug 42 at the bottom of the movable plate 4 into the insertion hole 32 in the fixed plate 3, and then release the adjustment handles 53 on both sides. At this time, the limit column 5 can automatically return to the limit cavity 43 in the plug 42 due to the elastic force of the spring 51, thereby fixing the plug 42 and assembling the movable plate 4 on the fixed plate 3. In this way, the installation rod 21 and the diaphragm assembly 2 can be assembled through the installation slot 6 between the movable plate 4 and the fixed plate 3.

[0030] In the present invention, the movable plate 4 can be conveniently installed on the fixed plate 3 through the adaptation setting between the plug-in 42 and the socket 32. The mounting rod 21 is clamped by the fixed plate 3 and the movable plate 4, so that the mounting rod 21 can be quickly disassembled and assembled, so that the diaphragm assembly 2 can be quickly disassembled for cleaning, which is convenient for the staff to operate.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
