This utility model relates to the field of filter-type sand separators and discloses a filter screen disassembly tool for filter-type sand separators. The tool includes a top plate, connecting parts, and at least two jacks. The connecting parts include connecting rods and several connectors. The connecting rods and connectors are detachably connected, and the connecting rods are fixedly connected to the top plate. The connectors are adapted to the filter screen. The jacks are centrally symmetrically arranged on the circumference of the top plate. This utility model provides a modular filter screen disassembly tool, addressing the problems of easily damaged filter screens and numerous disassembly tools in filter-type sand separators. It designs a disassembly device composed of a top plate, connecting parts, and multiple jacks. The connecting parts use replaceable connectors to adapt to different filter screen specifications. By applying force from one or more sides with the centrally symmetrically installed jacks, the filter screen is deformed evenly under force, achieving eccentric pull-out and avoiding damage caused by violent disassembly. This reduces the types of tools, lowers the filter screen damage rate, improves work efficiency and safety, and effectively saves costs.
