Iron phosphate calcined material cooling device

The utility model relates to an iron phosphate calcined material cooling device, and belongs to the technical field of cooling equipment. Comprising a rotating cylinder (3), a feeding pipe (1) and a discharging port (7) are arranged at the two ends of the rotating cylinder (3), material pipes (4) are arranged in the rotating cylinder (3) at intervals, the two ends of each material pipe (4) are communicated with the feeding pipe (1) and the discharging port (7) respectively, and a water inlet rotating connecting pipe (5) and a water outlet rotating connecting pipe (6) are arranged in the middle of a sealing plate (9) at the discharging port (7). Calcined materials of the device enter the internal material pipe (4) through the feeding pipe (1) and are cooled to the discharging port (7) to the subsequent process, and cooling water is placed in the rotary barrel (3), so that the heat exchange area is increased; meanwhile, the cooling water is heated through heat exchange and is discharged through a water outlet r
