Slow-speed slow-sliding type low-damage-rate fertilizer drying device

Abstract

The invention discloses a slow-speed slow-sliding type low-damage-rate fertilizer drying device, and belongs to the field of fertilizer drying devices. By arranging a breathable grain-dividing soft plate and soft cloth, the process that fertilizer particles are bagged by the soft cloth and slowly roll downwards and are dispersed along the surface of the breathable grain-dividing soft plate can be repeatedly achieved; on one hand, the fertilizer particles are in full contact with hot air, and the drying sufficiency and speed are effectively improved; on the other hand, the breathable grain-dividing soft plate provides flexible buffering and supporting for the fertilizer particles, the rolling speed of the fertilizer particles is reduced, flexible contact between the fertilizer particles and the breathable grain-dividing soft plate is achieved, and effective dual protection is provided for the fertilizer particles; and in addition, the breathable grain-dividing soft plate has a further flexible dispersing effect on agglomerated fertilizer in the rolling process, and the drying speed is further increased. According to the slow-speed slow-sliding type low-damage-rate fertilizer drying device, the damage rate of the fertilizer particles in the drying process is greatly reduced while the fertilizer particles are dispersed and drying is accelerated, the quality of the fertilizer particles is effectively guaranteed, and the high-quality and high-efficiency drying process is achieved for the fertilizer.

Description

technical field [0001] The invention relates to the field of fertilizer drying devices, in particular to a slow-speed, slow-sliding low-loss rate fertilizer drying device. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, macroelement water-soluble fertilizers, medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. [0003] After the fertilizer preparation is completed, granulation and drying operations are required, that is, to dry the granulated wet fertilizer. One is to place it in a static dryer for drying, but the drying efficiency is low. The other is to stir and stir the fertilizer during the drying process to ensure the unif...

Problems solved by technology

[0003] After the fertilizer preparation is completed, granulation and drying operations are required, that is, to dry the granulated wet fertilizer. One is to place it in a static dryer for drying, but the drying efficiency is low. The other is to stir and stir the fertilizer during the drying process to ensure the uniformity of drying, but it is easy to damage the formed fertilizer during the stirring process, causing it to crack or even break, thus affecting the quality of the product
