The invention relates to a filter bag frame which comprises a top supporting piece, steel wire ropes, multiple rope winders, a support rod, a base plate and multiple steel wire rope fixing pieces, wherein the top supporting piece comprises a pipe body which is longitudinally arranged; a support part formed by outward extension from the outer peripheral surface and a first fixing part formed by inward extension from the inner peripheral surface are arranged at the upper end of the pipe body; the pipe body is sleeved by the multiple rope winders for winding the steel wire ropes; one end of the support rod is in threaded connection with the first fixing part, and the other end of the support rod is detachably connected with the base plate; one end of each steel wire rope can be pulled out of the corresponding rope winder and fixed on the base plate; the multiple steel wire rope fixing pieces are arranged at intervals in the length direction of the support rod in a sleeving manner, and are provided with multiple fixing arms which are circumferentially distributed, radially extend and are used for fixing the steel wire ropes. The filter bag frame with such a structure can be conveniently assembled and used, so that the storage space is saved, and the transportation cost is reduced.
