Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel sand production, in particular to a drying device used for steel sand production. Background Art
[0002] Steel grit is a spherical particle made of special materials through special heat treatment. Steel grit is widely used for descaling and rust removal of steel workpieces before painting. In this case, centrifugal shot blasting equipment is often used. The spherical shape and smaller hardness prevent steel grit from causing greater wear on the equipment. Steel grit is made of molten iron. Currently, the more common steel grit preparation processes on the market are mostly divided into two types. One is cast steel grit. The process is to melt the raw materials into molten iron in an electric furnace and then pour it into water. When the molten iron meets water, it explodes into steel balls of varying sizes, which are then sieved, ignited, rusted, and packaged. Alternatively, an emerging separation process is used to centrifuge the molten iron into a water pool for cooling, and the cooling process is completed in the pool water. Both processes require the use of a key medium, that is, water, and water cooling is also required in other processing steps of steel grit. This directly leads to a certain amount of moisture on the surface of the steel grit after cooling. If it is not dried in time, a certain degree of corrosion and oxidation will be caused to the surface.
[0003] Most existing drying devices use electric heating to directly heat the air for drying, or hot air drying. However, hot air is prone to uneven airflow during drying, which affects the drying efficiency. Secondly, steel sand is prone to accumulation during centralized drying, resulting in uneven heating of the internal steel sand, thereby reducing the drying effect. Utility Model Content
