The invention discloses a movable tank type cooler. The cooler comprises a circular-groove-shaped cooling bin (1), a driving device (2) for driving the circular-groove-shaped cooling bin to move, an annular hot blast cover (3) arranged on the circular-groove-shaped cooling bin, at least one hot blast collection pipe (4) connected with the top or side portions of the hot blast cover, a cooling airchannel (5) which is arranged outside the circular-groove-shaped cooling bin and comprises a cooling air channel movable base and a cooling air channel fixing cover, an annular rotation rack (6) whichis arranged at the bottom of the circular-groove-shaped cooling bin and the bottom of the cooling air channel and provided with an air passing beam in a hollowed mode, an ore discharging hopper (7) arranged on the lower portion of the circular-groove-shaped cooling bin, a plurality of cooling fans (8) of which air outlets communicate with the cooling air channel through corresponding cooling airpipes, and a cooling air communicating pipe (9) arranged between the cooling air channel movable base and the annular rotation rack. All air leakage links are removed, the good leakproofness of the movable tank type cooler is ensured, and the waste heat recovery amount is greatly increased.
