Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane frames, in particular to a suspended MBR membrane frame. Background Art

[0002] MBR membrane rack reactor is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. It can be divided into flat membrane, tubular membrane and hollow fiber membrane according to the structure of the membrane, and can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane according to the pore size of the membrane. MBR is a highly efficient combination of membrane separation technology and biological treatment method, and is used to replace the secondary sedimentation tank in the activated sludge method.

[0003] The existing Chinese patent with publication number CN 217614038 U discloses a novel suspended MBR membrane frame reaction device, including a frame, a membrane assembly, a pipeline assembly, a reinforcement block and a suspension installation mechanism. The membrane assembly is arranged on the inner side of the frame, and the pipeline assembly is connected to the membrane assembly. The utility model optimizes the suspension installation mechanism, and the barrel cover can be rotated on the bottom side of the round block. The internal thread block on the inner side of the barrel cover cooperates with the threaded rod to move it outward or inward, so that the support can be rotated on the outer side of the arc frame through the support rod frame to change the position of the support. At the same time, the worm and the worm wheel can be cooperated by rotating the rotating block to adjust the position angle of the arc frame on the right side of the rectangular sheet, and then the installation position angle can be quickly adjusted through the support and the positioning frame, and the suspension support on the side wall of the membrane pool plays a role in rapid installation and disassembly.
