Drying device for chemical fertilizer

Abstract

The invention belongs to the technical field of chemical fertilizer production, particularly relates to a drying device for chemical fertilizer, and provides the following scheme for solving the problems in the prior art. The drying device comprises a barrel, a feeding mechanism is arranged at the top of the barrel, an exhaust shell communicated with the barrel is fixedly connected to the outer wall of the top of the barrel, and an exhaust pipe is fixedly connected to the outer wall of the top of the exhaust shell; and a discharging opening is formed in the outer wall of the bottom of the barrel, and a fixing rod is arranged over the discharging opening. Falling chemical fertilizer is scattered through bent rods, so that the chemical fertilizer is more dispersed, the drying effect of the chemical fertilizer is improved, the chemical fertilizer passing through the upper surface of a middle block can be dispersed, the drying effect of the chemical fertilizer is further improved, poor influence caused by damp air passing through the upper surface of an upper material guide area is prevented, and the drying efficiency is further improved; and the situation that the chemical fertilizercannot fall to the center of a material distributing plate, and consequently the material distributing plate disperses the chemical fertilizer unevenly is prevented, and the chemical fertilizer dispersion uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizer production, in particular to a drying device for chemical fertilizer. Background technique [0002] Chemical fertilizers are fertilizers made by chemical methods that contain one or several nutrient elements needed for the growth of crops. The abbreviation of chemical fertilizers is called unit fertilizers that contain only one nutrient element that can indicate the content, such as nitrogen fertilizer, phosphorus fertilizer, Potassium fertilizers and minor macroelement fertilizers and trace element fertilizers, chemical fertilizers containing two or three of the three nutrients nitrogen, phosphorus, and potassium, and their contents can be indicated, are called compound fertilizers or mixed fertilizers. [0003] In the production process of chemical fertilizers, in order to facilitate later storage and sales, it is usually necessary to use a drying device to dry chemical fertilizers. ...

AI Technical Summary

Problems solved by technology

[0003] In the production process of chemical fertilizers, in order to facilitate later storage and sales, it is usually necessary to use a drying device to dry chemical fertilizers. Because chemical fertilizers are usually easy to form small lumps due to moisture, it is easy to cause small lumps during drying. The inside of the fertilizer is difficult to dry, the drying effect is poor, and the efficiency is low
