The invention belongs to the technical field of a paper sludge incineration device, and particularly relates to a paper sludge transfer and storage silo, which comprises a sealed silo body, a screw feeder, a bottom axial-flow fan, a group of fire fighting nozzles, a material level meter, a double-end output drive device, a discharging chute, a belt feeding hopper, a belt conveyor and an accident ash-discharging pipe. The sealed silo body consists of a steel structural framework, a combined disc type bottom plate, a cylindrical silo wall and an umbrella-shaped silo roof, wherein the combined disc type bottom plate consists of a fixed disc, a rotary disc, a vertical rotating shaft and a base bracket, the fixed disc consists of a ring-shaped fixed plate, a central fixed plate and a ring-shaped power supply sliding contact line, and the rotary disc is provided with a sludge outlet, a ventilating manhole and a mounting hole. The sealed silo body is suitable for rotation and mixing of materials in the silo and the service life of the silo body is long. The screw feeder has the functions of revolution and rotation. Materials can be delivered into an appropriate position due to rotation while being mixed under effects of revolution, the problem of bypass of sludge materials can be avoided, and the efficiency of transfer and falling is high.
