Description

TECHNICAL FIELD

[0001] The utility model relates to the production field of drainage sand, concretely to a drying device for drainage sand production. BACKGROUND

[0002] The drying device for drainage sand production is mainly used for removing water in the drainage sand. If the drainage sand contains too much water, the water will rapidly vaporize when the high-temperature molten steel contacts it, which will produce a large amount of water vapor, and these water vapor may change the flowability of the molten steel, resulting in poor drainage of the molten steel.

[0003] The granular drainage sand processing drum kiln disclosed in the utility model is characterized by the following: the drum shell is provided with a stirring assembly, the drum shell is internally provided with a stirring space, the stirring space comprises an upper stirring space and a lower stirring space, and the upper stirring space and the lower stirring space are connected through a partition plate. The existing drying device for drainage sand production often encounters the problem of drainage sand condensing into blocks during operation, thereby significantly reducing the drying efficiency and affecting the overall production efficiency. The drainage sand has complex and diverse components, including various minerals and possible impurity components. Under the condition of moisture absorption, some soluble substances dissolve in the water. At the initial stage of drying, the concentration of these substances gradually increases with the evaporation of water, which plays the role of a bonding agent and promotes the mutual adhesion of drainage sand particles to form blocks. After the drainage sand is blocked, its internal structure becomes dense, and the water is wrapped inside the block and is difficult to escape. After the heat is transferred to the surface of the block, it is difficult to further penetrate the inside, greatly hindering the evaporation process of the water. Even if the blocked drainage sand is treated by crushing, there are still many problems. The crushed drainage sand is surrounded by other unblocked or large blocks of drainage sand and is in a relatively inner position. This positional relationship makes it difficult for heat to quickly penetrate the outer layer of drainage sand to reach the crushed block part, increasing the difficulty and length of drying, resulting in a significant extension of the drying time and reducing the production efficiency of the drying device.
