Efficient and energy-saving ammonia-acid process compound fertilizer production device

Abstract

The invention relates to fertilizer production equipment, and in particular relates to an emulgator for producing a nitro-sulfenyl slow-release fertilizer. The emulgator comprises a shell and a stirring shaft arranged inside the shell, wherein the upper end of the stirring shaft stretches to the outer side of the shell and is in transmission connection with a motor; the inner cavity of the shell is internally provided with a fixed barrel; the fixed barrel and the stirring shaft are coaxially arranged; the upper end of the fixed barrel is provided with a connecting spoke, and the lower end of the barrel is provided with a circular bushing; the connecting spoke is fixedly connected between the fixed barrel and an upper shaft sleeve; the upper shaft sleeve sleeves the stirring shaft; the circular bushing sleeves the stirring shaft through a bearing; an annular bushing is fixedly connected between the outer wall of the fixed barrel and the inner wall of the shell; a plurality of through holes are formed in the circular bushing and the annular bushing; the stirring shaft between the connecting spoke and the circular bushing is provided with a main fin. The emulgator can push materials to move vertically while stirring, so that the materials with different specific gravities are mixed more uniformly, the emulsifying efficiency is improved, and thus the emulgator is beneficial for improving the product quality of a nitro-sulfenyl high tower slow-release fertilizer.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to a high-efficiency energy-saving amino acid method compound fertilizer production device. Background technique [0002] In the production process of compound fertilizer by acid method, whether the slurry is mixed uniformly is the key factor affecting the appearance and granulation of the product, but because the composition of the compound fertilizer is complex and there are many raw materials, it is necessary to mix and fully emulsify a variety of liquids with different specific gravity , to carry out the next production process, but in the emulsification process, the existing emulsifiers for fertilizer production have simple structure and high production efficiency, but most emulsifiers only use spiral stirring, and can only stir at the same plane height The material cannot drive the material to move vertically. When the specific gravity of different materials differ...

[0002] In the production process of compound fertilizer by acid method, whether the slurry is mixed uniformly is the key factor affecting the appearance and granulation of the product, but because the composition of the compound fertilizer is complex and there are many raw materials, it is necessary to mix and fully emulsify a variety of liquids with different specific gravity , to carry out the next production process, but in the emulsification process, the existing emulsifiers for fertilizer production have simple structure and high production efficiency, but most emulsifiers only use spiral stirring, and can only stir at the same plane height The material cannot drive the material to move vertically. When the specific gravity of different materials differs greatly, it will cause uneven emulsification, poor emulsification effect, low efficiency, and affect the overall quality of the fertilizer.
