Description
TECHNICAL FIELD
[0001] The utility model relates to ammonium phosphate processing field especially relates to a drying device for ammonium dihydrogen phosphate processing and production. BACKGROUND
[0002] The drying device is the equipment that removes water or other solvents in materials by means of heating, ventilation, pressure reduction, etc. It is crucial to use the drying device in ammonium dihydrogen phosphate processing and production. The humid environment is easy to make ammonium dihydrogen phosphate caking, deliquesce, reduce product purity and stability. Drying can effectively avoid such conditions, improve product quality and make it meet the standards. The water content of dried ammonium dihydrogen phosphate is low, which is beneficial to long-term storage and long-distance transportation, can reduce the problems of microbial growth and packaging damage in storage. At the same time, the subsequent processing steps often have strict requirements on the water content of materials. Dry materials are easier to process and form, which ensures smooth processing and product consistency. In addition, drying treatment can also improve the fluidity and dispersibility of materials, making the conveying, metering and mixing operations more efficient, reducing production failures and delays, and thus improving overall production efficiency.
[0003] The working principles of existing drying devices for ammonium dihydrogen phosphate processing and production are different. The airflow drying device disperses materials by high-speed hot air flow, transfers heat by convection to evaporate water, and at the same time completes conveying. The drying speed is fast. The fluidized bed drying device lets hot air pass through the perforated plate, lifts the materials to form a fluidized bed, and the materials and hot air are fully mixed and contacted. The water is evaporated by conduction and convection. The drying is uniform and the residence time is controllable. The rake type drying device relies on rotating rake teeth to turn and stir the materials. The heating medium in the jacket transfers heat through the jacket wall. The water is discharged through the exhaust port. It is suitable for materials with high viscosity or water content. The spray drying device atomizes ammonium dihydrogen phosphate solution into mist droplets, fully exchanges heat with hot air, and makes water evaporate quickly. The product particle size is uniform and has good fluidity. It is suitable for situations with high requirements on product particle size and solubility.
[0004] In ammonium dihydrogen phosphate processing and production, stable operation of the drying device is crucial. Taking the rake type drying device as an example, the rake head, as the core component, is in frequent contact with materials during long-term use, bearing a large friction force and mechanical stress. It is prone to wear, deformation, and even breakage. Once the rake head is damaged, the materials cannot be fully turned and stirred, leading to uneven heating of the materials. Some materials cannot effectively contact the drying heat source, and water evaporation is hindered. As a result, the drying efficiency of the entire equipment is greatly reduced, seriously affecting the efficiency of the drying device for ammonium dihydrogen phosphate processing and production, and thus slowing down the entire production process and increasing production costs.
