Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device for magnesium sulfate production. Background Art

[0002] The drying process in the magnesium sulfate production process is mainly to remove moisture from the material through specific drying equipment and processes to achieve specific product quality requirements. The drying process is crucial in the production of magnesium sulfate because it can ensure the stability, purity and quality of the product.

[0003] According to the publication number "CN213901779U", the stirring blades can cooperate with the rotation of the wheel to turn the magnesium sulfate powder entering the drying box, so that the magnesium sulfate powder in each layer can be better heated. In addition, the nozzles can cooperate with the rotation of the stirring blades to blow the turned magnesium sulfate powder, so that the magnesium sulfate powder can better contact with the hot air, thereby improving the drying efficiency of the magnesium sulfate powder.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: the rotating nozzle can only rotate and blow at a certain height. Due to the large internal space of the box, it is difficult for the material to be evenly exposed to the hot air, resulting in poor drying effect and prolonged drying time. Secondly, the entire box cannot be disassembled, and the residual material inside cannot be lifted up and cleaned, resulting in accumulation into blocks, which affects the subsequent drying process.
