This framework 5 comprises a rigid brace consisting of a frame 10 made up of a curved tubular member provided with a support flange 16 for fitting the framework through a passage 9 provided in the base plate 4 of a filtration chamber. The frame is covered with a filter bag 18. According to the invention the walls of the bag 18 are held at a substantially uniform distance from each other by a set of metallic and parallel unclogging springs 23 fitted between the side 13 of the frame 10 opposite the base plate and a hooking member 22 situated in the vicinity of the supporting flange 16, the tension of these springs being sufficiently low in order that, during an injection of compressed air inside the bag through the flat conduit, these springs are caused to vibrate mechanically, beating these walls in order to improve the unclogging, in addition to the separation of the walls of the bag opposite the springs. Application to the filtration of any industrial plant by means of framework for supporting removable and replaceable filter elements. <IMAGE>
