A centrifugal roller barrel heat preservation cover

Abstract

A centrifugal roller body heat preservation cover belongs to the technical field of casting equipment, including cover cylinder and mechanical iris set on the upper and lower ends of the cover cylinder to play a sealing role, the mechanical iris includes ring shell set on the upper end or lower end of the cover cylinder, rotating frame assembled in the ring shell by means of vane group and matched end cover; The rotating frame is uniformly distributed with 8-16 slide grooves of the same shape and size in the circumferential direction; The ring shell is uniformly distributed with 8-16 rotating grooves of the same shape and size in the circumferential direction, and the rotating grooves are located at the central position of the inside diameter of the ring shell; The number of vanes is 8-16, and the shape is arc-shaped; The center of the end of each vane is respectively provided with a rotating column and a sliding column, the rotating column is assembled in the corresponding rotating groove of the ring shell, and the sliding column is assembled in the corresponding sliding groove of the rotating frame. The upper end and the lower end of the heat preservation cover adopt the same mechanical iris structure to seal the whole heat preservation cover, so as to achieve the effect of roller body heat preservation sealing.
