AI Technical Summary
In existing potassium chloride drying equipment, the moisture from the potassium chloride can easily clog the pores of the air permeable plate during the drying process, resulting in insufficient drying. Furthermore, the lack of an effective heat recovery device leads to low heat utilization.
A potassium chloride drying device was designed, which includes a crushing device, a drying device, and a recovery device. The potassium chloride is crushed by stirring and crushing the component, dried by hot air delivered through a heated filter box, and the waste heat is recovered by the recovery component to avoid heat waste.
This method improves the drying efficiency and heat utilization of potassium chloride, avoids clogging of the pores and heat waste, and achieves a more efficient drying effect.
