Blast furnace sedimentation tank water granulated slag treatment device

A fluidization tank is arranged beside the sedimentation tank of the blast furnace, the fluidization tank is a V-shaped tank or a U-shaped tank with two closed ends, jet water pipes with holes are arranged at the bottom and the side face of the fluidization tank, and the jet water pipes penetrate through the end face of the fluidization tank to be connected with a water supply pipeline. A slurry outlet of the fluidization tank is connected with an inlet of the filter press through a slurry pump and a pipeline, a slag outlet of the filter press is in butt joint with the belt conveyor, and a water outlet of the filter press is connected with the water suction well through a pipeline. The fluidization tank, the slurry pump, the pipeline, the filter press and the belt conveyor are arranged, sothat salvaged sediment water slag is fluidized, conveyed by the slurry pump and subjected to filter pressing by the filter press, a mud cake belt conveys the sediment water slag, backwater is recycled, the links of outward t
