Portable membrane shell dismounting tool for DTRO (Disk Tubular Reverse Osmosis) membrane column

The utility model relates to a portable DTRO membrane column membrane shell dismounting tool which comprises a base, a movable rod, a lifting assembly and a membrane shell lifting block, the movable rod is rotationally arranged on the base, and the membrane shell lifting block is fixedly connected with the lifting assembly; the lifting assembly is movably arranged on the movable rod and used for controlling the membrane shell lifting block to move towards the side, away from the base, of the movable rod. When the tool is used, the base of the membrane shell disassembling tool is fixed to a membrane column frame, then the membrane shell lifting block is adjusted to a proper angle by rotating the movable rod, and then the membrane shell lifting block is controlled by the lifting assembly to move towards the side, away from the base, of the movable rod; and after the lifting block moves towards one side, far away from the base, of the movable rod, the membrane shell of the DTRO membrane column is jacked up, so t
