Automatic drying machine for water-soluble fertilizer

Abstract

The invention discloses an automatic drying machine for water-soluble fertilizer. The automatic drying machine is characterized in that a top drying chamber is fixed to the top of a drying chamber, acenter pipe is fixedly hung in the middle of the top drying chamber, the lower portion of the center pipe is inserted into the lower portion of the drying chamber, and multiple sets of material distribution rods are fixed to the inner side of the center pipe; the upper portion of the drying chamber is of a conical barrel structure, an air chamber is fixed to the lower portion of the drying chamber, and a fixing plate is fixed to the connecting position of the drying chamber and the air chamber; a conical material distribution cone is fixed to the center of the fixing plate, the upper portion of the material distribution cone is inserted into the center pipe, and a gap is formed between the side portion of the material distribution cone and the lower end of the material distribution cone; and multiple sets of core pipes in the vertical direction are fixed to the edge of the fixing plate, the upper portions of the core pipes are inserted into an outer sleeve, multiple sets of small holesare formed in the side wall of the lower portion of the outer sleeve, and the inlet ends of the core pipes communicate with the air chamber. The automatic drying machine has the advantages of being high in drying efficiency and good in drying uniformity.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizer production, and in particular relates to an automatic dryer for water-soluble fertilizer. Background technique [0002] Water-soluble fertilizer is a fertilizer that can be quickly and completely dissolved in water. It can be used with agricultural irrigation facilities to realize the integration of water and fertilizer in agricultural production. Water-soluble fertilizers are mainly made by mixing high-purity urea, ammonium phosphate, ammonium nitrate and other chemical raw materials. In this way, because the wet fertilizers are easy to agglomerate, the uniformity of mixing is poor. At the same time, the agglomerated fertilizers have poor drying uniformity and a long drying time, which affects the production of enterprises. Therefore, the present invention proposes an automatic dryer for water-soluble fertilizers to solve the above problems. Contents of the invention [0003]...

AI Technical Summary

Problems solved by technology

Water-soluble fertilizers are mainly made by mixing high-purity urea, ammonium phosphate, ammonium nitrate and other chemical raw materials. Because the wet fertilizer is easy to agglomerate, the uniformity of mixing is poor, and the uniformity of drying of the agglomerated fertilizer is poor, and the drying time is long, which affects the production of the enterprise.
