The invention discloses a framework-type thrust plate of a filter press. A frame body is formed by welding strength rib plates on main cross beam plates; the main cross beam plates are through opening connecting main beams; base plates and inner rib plates are welded inside openings of the main cross beam plates at the two ends of the frame body and are provided with bolt holes; side rib plates and reinforced rib plates are welded on the frame body and are connected with cross rib plates so as to form the framework-type frame body; the two sides of the frame body formed by the main cross beam plates and the strength rib plates are subjected to balanced stress; a sealing panel of the framework-type thrust plate is connected with a filtering plate with large strength and flatness, so that material leakage is prevented; the sealing panel is welded on the side surface of the thrust plate; a feeding flange pipeline is welded in the center of the sealing panel; liquid outlet flange pipelines are welded at the four corners of the sealing panel; a hoisting hook is installed at the upper end of the thrust plate; box-type support legs are installed at the lower end of the thrust plate; and ground plates are connected with a basic plane.
