Description

Technical Field

[0001] The utility model relates to the technical field of high-tower granulation compound fertilizer production, in particular to a screening device for high-tower granulation compound fertilizer production. Background Art

[0002] Solid urea or ammonium nitrate is heated and melted to form a molten liquid, or the molten liquid after evaporation and concentration can be used directly. The corresponding phosphate fertilizer, potash fertilizer, filler and additives are added to the molten liquid to make a mixed slurry. The mixed slurry is sent to the high tower granulator for spraying and granulation. The granulated material sprayed into the granulation tower by the granulator interacts with the gas resistance rising from the bottom of the tower during the process of descending from the high tower, and after heat exchange with the gas resistance, it falls to the bottom of the tower. The granular material falling to the bottom of the tower is screened and surface treated to obtain granular compound fertilizer.

[0003] In the prior art, the screening device for high-tower granulated compound fertilizer production usually performs continuous screening through an inclined screen plate during screening. Since the movement speed of the high-tower granulated compound fertilizer on the inclined screen plate is uncontrolled, it is easy for larger particles of the high-tower granulated compound fertilizer to roll down too quickly, making it difficult to fully screen and discharge the larger high-tower granulated compound fertilizer on the surface, thereby reducing the accuracy of the screening device for high-tower granulated compound fertilizer production and reducing the practicality of the screening device for high-tower granulated compound fertilizer production. Therefore, a screening device for high-tower granulated compound fertilizer production is needed. Utility Model Content
