[0002] Drainage sand is an indispensable refractory material for steelmaking in eccentric furnaces. The requirements for it in industrial production are constantly increasing, and it is required to enable the ladle to open and pour automatically. If the ladle water inlet cannot open automatically, oxygen drainage treatment must be carried out. Auxiliary drainage will cause a considerable amount of molten steel to be poured open, causing secondary oxidation, affecting the quality of molten steel, increasing pouring costs, and threatening the safety of equipment and operators. Experiments have found that when the water content in the drainage sand is greater than 0.5%, the probability of failure to open automatically increases by at least 85%. Therefore, the drainage sand needs to be dried before use. However, the existing drainage sand drying device has low drying efficiency and cannot achieve continuous drying of the drainage sand. At the same time, most of them use sealed drying boxes, which prevents water vapor from dissipating in time and increases the drying time. Utility Model Content
