A slow-sliding type low-loss fertilizer drying device

Abstract

The invention discloses a slow-speed, slow-sliding and low-loss rate fertilizer drying device, which belongs to the field of fertilizer drying devices. By setting a breathable grading soft board and a soft cloth, the fertilizer granules can be bagged repeatedly by the soft cloth, and can be bagged along the air-permeable grading line. On the one hand, the fertilizer particles are fully in contact with the hot air, which effectively improves the drying adequacy and speed; on the other hand, the breathable grading soft board provides flexible cushioning and support for the fertilizer particles, reducing Its rolling speed and its flexible contact with it provide effective double protection for the fertilizer particles, and the air-permeable grading soft board has a further flexible dispersion effect on the agglomerated fertilizer during the rolling process, which further improves the drying rate. While dispersing fertilizer particles and accelerating drying, it greatly reduces the damage rate of fertilizer particles during the drying process, effectively guarantees the quality of fertilizer particles, and realizes a high-quality, high-efficiency drying process for fertilizers.

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
