Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an MBR membrane frame. Background Art

[0002] MBR is the abbreviation of Membrane Bio-Reactor. MBR refers to a new sewage treatment device that combines ultrafiltration and microfiltration membrane separation technology with bioreactors in sewage treatment.

[0003] The current MBR membrane frame is mainly composed of membrane filaments and a membrane shell connected and fixed at the upper and lower ends. The current installation method is mainly to install the membrane filaments on the membrane shell through epoxy resin glue. For example, the patent number is CN101746880B, and the patent name is a Chinese patent for a membrane filament bundle filling and a rotatable hollow fiber membrane assembly with a horizontal water collection pipe. However, the above installation method has the following problems when used: Since the MBR membrane frame is mostly used in an immersed manner, the membrane filaments will shake and tremble in the MBR membrane frame under the action of the aeration equipment. Long-term use is likely to cause the membrane filaments and the membrane shell to break at the glue joint. And affect the treatment of sewage. In addition, the patent number is CN203794692U, and the patent name is Chinese patent for MBR membrane assembly to prevent membrane wire breakage. In order to prevent the problem of membrane wire breakage, the upper and lower membrane boxes are respectively provided with upper and lower protective grids to prevent excessive shaking. The upper and lower protective grids can effectively slow down the shaking and jittering of the membrane wire in the direction perpendicular to the upper and lower protective grids. However, shaking and jittering will still occur in the direction parallel to the upper and lower protective grids, and the shaking and jittering direction of the membrane wire is not fixed. Therefore, it is difficult to effectively solve the problem of membrane wire breakage caused by long-term use. Utility Model Content

At the same time, the end of the membrane wire harness 2 passes through the first through hole 12, and Extend into the hollow cavity 7 of the lower membrane shell 4, then install the two support rods 5 in the first installation groove 10 of the lower membrane shell 4 respectively, and at the same time, insert the connecting pipe 8 into the hollow cavity 7 of the lower membrane shell 4, then pour the epoxy resin glue into the first installation groove 10, the second installation groove 11 of the lower membrane shell 4 and the third installation groove 13 of the outer shell 6 for gluing and sealing. During the gluing process, the epoxy resin glue in the third installation groove 13 enters into the membrane wire harness 2 through the glue injection through hole 102 provided on the membrane wire protective cover 1, and the membrane wire harness 2 is sealed and fixed;

[0056] After the epoxy resin glue at the lower membrane shell 4 solidifies, rotate 180°, insert the other end of the support rod 5 into the first mounting groove 10 of the upper membrane shell 3, insert the connecting pipe 8 into the hollow cavity 7 of the upper membrane shell 3, and install the other end of the membrane wire bundle 2, the membrane wire protection cover 1 and the outer shell 6 in the second mounting groove 11 of the upper membrane shell 3.
