Drying device for fertilizer production process

Abstract

The invention discloses a drying device for a fertilizer production process. The drying device for the fertilizer production process comprises a machine body, wherein an upper drying chamber is installed at the upper end of the machine body, a lower drying chamber is installed at the lower end of the machine body, and support legs are installed at the bottom end of the machine body; the bottom end of the upper drying chamber is connected with the lower drying chamber through an electronic control valve; a first drying barrel is installed at the middle end in the upper drying chamber, and a first interlayer is installed at the outer side of the first drying barrel; and a second drying barrel is installed at the middle end in the lower drying chamber, and a second interlayer is installed at the outer side of the second drying barrel. According to the drying device for the fertilizer production process, which is disclosed by the invention, a design of the double drying chambers is adopted for multi-stage drying, and a good drying effect and high drying efficiency are achieved; and sterilization treatment can further be carried out on materials during drying, and the drying device is abundant in function, simple to operate, and convenient to use.

Description

technical field [0001] The invention relates to a drying device for fertilizer production, in particular to a drying device used in the fertilizer production process. Background technique [0002] In the process of producing chemical fertilizers, the drying of chemical fertilizers is an extremely important process. If the drying does not meet the requirements, the fertilizers will agglomerate, which seriously affects their fertility and is not conducive to storage. Existing fertilizer drying devices generally include tumble dryers, hot air drying ovens, microwave dryers, etc. The tumble dryer is designed as a slightly inclined and rotatable cylinder. The drying efficiency of this type of drying equipment is Low, and high energy consumption; hot air drying furnace, there are still some wind dead angles in the drying process, the drying is not comprehensive enough, and the material is directly discharged after drying, which cannot ensure that the fertilizer is completely dr...
