Preferably, the interior flow-guiding screen and outer flow-guiding screen are mainly made of rectangular shaped rim and grid screen, the rectangular edges It is fixed with grid screen in frame, is provided with multiple-sealed between the rectangular shaped rim and the first rectangular channel of the interior flow-guiding screen, it is described It is additionally provided with multiple sealed grooves in the rectangular shaped rim of interior flow-guiding screen, sealing ring is provided in the sealed groove, it is described to lead outside The rectangular shaped rim of drift net is sealed for compressing sealing ring.
Preferably, the spacing between the grid screen and diaphragm is 1-2mm.
Preferably, the bolt hole being connected to catch basin is provided at the top of the rectangular box, the outlet pipe is mounted on In bolt hole.
Compared with prior art, the utility model has following technical effect that the utility model structure is simple, user Just, fixation is sealed to diaphragm using detachable structure, disassembling, assembling and replacing diaphragm is convenient;And the two sides of diaphragm pass through flow-guiding screen It is gripped, and there are the gaps of 1-2mm between diaphragm and flow-guiding screen makes film while guaranteeing diaphragm water flowing area Piece is protected, and support protection well can be carried out to diaphragm by either filtering and backwashing in this way, can be realized online Cleaning, avoids diaphragm from being split up, keeps membrane bioreactor more convenient to use with continuous operation.
