Circular cooler arc sealing type trolley

A circular cooler arc sealing type trolley belongs to the technical field of oxidized pellet production, and comprises a head arc, a tail arc, a body and a trolley frame fixing beam arc, wherein the head arc and the tail arc are respectively embedded with the trolley frame fixing beam arc, gas are reserved and form heat expanding spaces, arc shapes are directly made at the head and the tail of each trolley of a circular cooler, and when the arc parts of the head and the tail of the trolley are lifted in the operation process, the head arc and the tail arc are respectively combined with the trolley frame fixing beam arc in an embedding way, so that oxidized pellets can be prevented from falling into an ash box. The trolley has the advantages that the structure is simple, an installation mode similar to an earlier mode is adopted, and the running is stable, material leakage is avoided, requirements on installation accuracy of a circular cooler trolley pressing rail are reduced, the daily maintenance amount of t
