Abstract

A composite frame type drying filter press comprises numbers of filter frames facing each other. A filter board is disposed between each two of the filter frames, so that the filter frames and filter boards are arranged in sequence. The sides of the filter frames define a filter room having two communicating sides. A slurry pipe communicating with the filter room is disposed along the frame side. Any of the filter board comprises a heating board, side filter nets, fixed frames and side filter webs. The heating board defines a sealed room and comprises a supporting frame to connect a heat introduction pipe and a heat exhaustion pipe for the heat sources to enter and leave the heating board. Water contained in the slurry may be vaporized, so that the wasted water may be exhausted through the side filter nets, side filter webs and waste exhaustion pipes of the fixed frames to increase the slurry drying efficiency. The filter board may be applied to various sizes of filter rooms with suitable filter frames, so that it is easier to make and assemble filter materials. The life cycle of the filter materials may be increased. In addition, the slurry may be removed more efficiently from the filter frames.
