A After concentrated slurry by cyclone filtration machine to settling of suspended material in reservoir, although dehydrated cake of the sludge, increases the footprint of the reservoir and dewatering system, unable continuous operation processing efficiency is low.
A linking the dewatering device via the valve V5 the cyclone filtration machine 1. Dehydrating apparatus body 2, the filtering tube 21 which is connected to the tapered pipe 23 is a straight pipe 22 filtering wall (multiple holes 23a Toro fabric 24), a housing 31 covering the outer peripheral space of the filtration tube 21, filter cloth 54 after and lower lid 51 for sealing / opening the lower side of the filter tube 21 provided with a water passing layer 53, made of connecting pipe 41. directly connected to a straight pipe 22, it takes in the slurry in the filtration tube 21, connecting tube 41 and by controlling the opening and closing of the housing 31 connected to air supply tube and the lower lid 51 72,77,78 and wastewater and exhaust pipe 73,74,76 performs caking by insufflation dewatering of the slurry to open the lower cover 51 to discharge the cake Te.
