[0026] As Figures 1 to 6 As shown, the side wall of heat exchange box 1 is hingedly connected with cover plate 2, the middle part of cover plate 2 is rotatably connected with rotating handle 21, the side wall of rotating handle 21 is fixedly connected with first gear 22, the middle part of cover plate 2 is rotatably connected with first tooth ring 23, first gear 22 and first tooth ring 23 are meshed, the middle part of first tooth ring 23 is fixedly connected with matching rod 24, when working, after the steel slag is placed into the inside of material cylinder 15, cover plate 2 is rotated to make cover plate 2 adhere to the side wall of material cylinder 15, when the steel slag in the inside of material cylinder 15 needs to be stirred, rotating handle 21 can be rotated to drive first gear 22 to rotate, first gear 22 and first tooth ring 23 are meshed to drive first tooth ring 23 and matching rod 24 to rotate, when matching rod 24 rotates, matching rod 24 can contact matching block 110 and drive matching block 110 and transmission shaft 18 to rotate, finally stirring rod 19 is rotated to stir the steel slag in the inside of material cylinder 15, after stirring is completed, matching rod 24 is rotated again to make matching rod 24 separate from matching block 110, so that heat is not easily conducted to rotating handle 21, the situation that personnel is scalded when operating is reduced, through the above structure, heat loss during heat recovery can be reduced, and when the steel slag in the inside of material cylinder 15 needs to be stirred, the situation that the operator is scalded in the hand is reduced, and the use safety of the device is improved.
