Drying technology for green organic compound fertilizer after granulation forming

Abstract

The invention belongs to the technical field of fertilizer production, and particularly relates to a drying technology for a green organic compound fertilizer after granulation forming. The technology is completed by adopting a drying device for the green organic compound fertilizer after granulation forming in a cooperative mode, and comprises the following steps that S1, conveying is carried out, and specifically, fertilizer granules on the upper surface of a material containing disc slide to the upper surface of a heating disc from a first falling groove; S2, heating is carried out, wherein a main shaft and the heating disc are driven to rotate through a driving motor, the fertilizer particles on the heating disc slide towards the edge of the heating disc under the action of centrifugal force and absorb heat of the heating disc, and water in the fertilizer particles overflows from an air outlet groove after being evaporated; S3, cooling is carried out, wherein the fertilizer particles enter a material guide pipe through a second material falling groove, and air cools the fertilizer particles and takes away residual moisture on the surfaces of the fertilizer particles at the same time; and S4, material taking is carried out, the fertilizer particles fall into an annular material receiving box, the annular material receiving box is taken down, and the fertilizer particles are poured out. According to the drying technology, when the fertilizer particles are dried, the situation that the fertilizer particles are broken is avoided, and the situation that the fertilizer particles are bonded in the annular material receiving box is avoided.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a green organic compound fertilizer drying process after granulation and molding. Background technique [0002] Green organic compound fertilizer refers to chemical fertilizers containing two or more nutrient elements. Green organic compound fertilizer is processed from biomass, animal and plant waste, and plant residues. Green organic compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. The green organic compound fertilizer needs to be dried after granulation. At present, there are the following problems when drying the green organic compound fertilizer granules: (1) The cohesive force inside the green organic compound fertilizer granules is wea...
