Problems solved by technology

[0002] Coated potassium sulfate granules are a kind of slow-release potassium fertilizer. The existing production method is to process potassium sulfate powder through granulation, sieving, drying, cooling and coating. At present, in the production process of potassium sulfate granules, The drying drum is generally used for drying the particles. Due to the large space of the drying drum, the accumulation of material particles has poor air permeability, which makes the drying insufficient and uneven, which affects the quality of the product.

Abstract

The invention discloses a chemical raw material drying device. The chemical raw material drying device comprises a box body; the bottom of the box body is fixedly connected with a set of air conveyingpipes; the upper side of the box body is hinged with a sealing cover; a separation box is rotationally connected into the box body; the separation box comprises an upper frame; the upper frame is a square frame; rotating shafts are fixedly connected to two opposite sides of the upper frame; the rotating shafts are rotationally connected with the corresponding inner side walls of the box body; semicircular plates are fixedly connected to the two ends of the bottom of the upper frame; a set of arc plates hinged to the upper frame is alternately arranged between the two semicircular plates; oneends of the arc plates are hinged to one side of the bottom of the upper frame; and the other ends of the arc plates are fixedly connected with the other side of the bottom of the upper frame throughhanging hook springs. A gap is formed between the two connected arc plates, and is intermittently generated in continuous swinging process; and materials in the separation box fall from the generatedgap to fully contact with drying hot air on the lower side to achieve the drying uniformity.
