Description

Technical Field

[0001] The utility model belongs to the technical field of granular potassium sulfate production, and in particular relates to a drying device for producing high-strength granular potassium sulfate. Background Art

[0002] At present, 40% of the world's potash fertilizers are processed into granules. Compared with powdered fertilizers, granular fertilizers have better physical properties, do not generate dust during loading and unloading, do not agglomerate during long-term storage, have good fluidity, are easy to spread, and can be applied mechanically. At the same time, they can also play a moderate slow-release role and improve the utilization rate of fertilizers. In the production process of potassium sulfate granular fertilizers, it is often necessary to use a drying device to dry them to assist their production and processing.

[0003] The existing patent with publication number CN220339025U proposes a drying device for the production of potassium sulfate granular fertilizer. The device cooperates with an atomizing plate to atomize the gas heated at high temperature, reduces its flow velocity, and injects it into the interior of the high-temperature guide tube. The heat source inside the high-temperature guide tube is uniformly guided into the interior of the downward inclined temperature conduction plate by the gas outlet. However, when the device dumps the granular potassium sulfate on the downward inclined temperature conduction plate into the interior of the collecting tube in the later stage, due to the large downward inclined temperature conduction plate, the remaining granular potassium sulfate will be dumped onto the ground if dumped directly, causing pollution. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a drying device for producing high-strength granular potassium sulfate.

[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:
