Rapid drying device for formed chemical fertilizers

Abstract

The invention relates to the technical field of chemistry, and discloses a rapid drying device for formed chemical fertilizers. The rapid drying device for the formed chemical fertilizers comprises adrying barrel, wherein the outer surface of the drying barrel is fixedly connected with a heat preservation and insulation pad; the upper end of the drying barrel is provided with a heating hole; an electric heating pipe is movably clamped in the heating hole; the upper end of the drying barrel is provided with a sealing cover; supporting legs are fixedly connected to the lower end of the drying barrel; a motor is fixedly connected to the lower surface of the drying barrel; a discharging port is formed in the outer surface of the drying barrel; and a blocking plate is arranged in the discharging port. According to the rapid drying device for the formed fertilizers, the fertilizers in the drying barrel is turned up and down, so that the fertilizers can form a material curtain, the fertilizers at the bottom can be in uniform contact with heat, the caking phenomenon caused by non-uniform heating due to fertilizer accumulation is avoided, the heating efficiency of the fertilizer is improved, the drying speed is increased, the drying time is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a quick drying device for chemical fertilizers after molding. 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] In the production of fertilizers, it is necessary to dry the granulated fertilizers to form dry solid particles, which are convenient for storage and transportation. Most of the existing drying equipment is to stir the fertilizer during the drying process of the fertilizer. Most of the stirring methods are rotating and stir...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a quick drying device for chemical fertilizers, which has the advantages of being able to turn the fertilizer up and down to form a material curtain, thereby enabling the fertilizer to fully contact with heat, etc., to solve the problem of Due to the pressure generated by the accumulation of fertilizers on the upper layer during the stirring process, the fertilizers on the lower layer cannot fully contact with the heat after stirring, which will cause the fertilizer on the upper layer to dry first, while the lower layer The fertilizer is still in the dry state, and it needs to be dried continuously, and because the fertilizer on the upper layer has been dried, further drying will cause organic matter to volatilize the dried fertilizer on the upper layer, which will affect the effect of fertilizer use
