[0023] After the sewage is treated, the block 16 is driven to disengage from the inside of the slot 15 by adjusting the assembly, so that the lock between the grid body 1 and the frame plate 3 is released, and then the staff pulls the handle 8 to remove the frame plate 3 from the inside of the embedded groove 2 and clean and replace the filter membrane 9 inside the container 4 accordingly, thereby reducing the use of cleaning and maintenance of the filter membrane 9 and facilitating the dredging of the grid body 1, thereby improving the filtration efficiency of the multi-stage filter membrane grid, making the multi-stage filter membrane grid more conducive to sewage treatment.

[0024] like Figure 1-Figure 5 As shown, the adjustment component includes a cavity 17, which is opened inside the grid body 1, and a slide plate 18 is slidably connected between the inner walls of the cavity 17. One side of the slide plate 18 is fixedly connected to the block 16, and the other side of the slide plate 18 is fixedly connected to a connecting rod 19. A spring 11 is fixedly connected to the outside of the connecting rod 19 and between the slide plate 18 and the inner wall of the cavity 17. One end of the connecting rod 19 extends to the outside of the grid body 1 and is fixedly connected to a pull-out block 10.

[0025] By pulling the pull-out block 10, the block 16 moves toward the inside of the cavity 17 under the action of the slide plate 18, so that the inclined end of the block 16 disengages from the inside of the slot 15, thereby releasing the lock on the frame plate 3, thereby facilitating the staff to quickly clean and replace the filter membrane 9 inside the tank 4, thereby improving the filtration efficiency of the multi-stage filter membrane grid.
