Granulation processing device for compound fertilizer and granulation processing method of device

Abstract

The invention relates to the field of compound fertilizers, and in particular relates to a granulation processing device for a compound fertilizer and a granulation processing method of the device. The device comprises a urea dissolution tank, a mixing dissolution tank and a drum granulator; a first stirring machine is arranged at the top of the urea dissolution tank, one side of the upper part ofthe urea dissolution tank is provided with a urea inlet, and the other side of the urea dissolution tank is provided with a first overflow opening; the first overflow opening is connected to the interior of the mixing dissolution tank through a pipeline, the top of the mixing dissolution tank is provided with a second stirring machine, the side of the mixing dissolution tank is provided with a powder inlet, and the side of the mixing dissolution tank is provided with a second overflow opening; and the drum granulator is provided with slurry spray heads, the second overflow opening is connected to the slurry spray heads through a pipeline, and the material outlet end of the drum granulator is connected with a rotary dryer, a drum cooler, a screening machine and a film wrapping machine in sequence. The processing device provided by the invention is simple, high-efficiency and low-cost, and the compound fertilizer produced by the device has a uniform particle size and smooth particles.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a compound fertilizer granulation processing device and a granulation processing method. Background technique [0002] With the development of people's life, agriculture is gradually growing. In order to improve the growth environment and harvest benefits of crops, it is necessary to sprinkle compound fertilizers on the farmland according to different seasons, climates, and soil environments. Compound fertilizers refer to nutrients containing two or more Elemental chemical fertilizers and compound fertilizers have the advantages of high nutrient content, less auxiliary components and good physical properties. They play a very important role in balancing fertilization, improving fertilizer utilization, and promoting high and stable crop yields. Usually the appearance of compound fertilizer is a small particle, but the traditional production process is too simple, just simple cr...

AI Technical Summary

Problems solved by technology

Usually the appearance of compound fertilizer is a small particle, but the traditional production process is too simple, just simple crushing, mixing, granulation, coating, packaging, resulting in the production of particles of different sizes, and the shape of the particles is not full , there are defects or the appearance is relatively rough, and the particle size and quality are not balanced, which leads to uneven fertilization during the fertilization process of workers. At the same time, fertilizers with larger particles are not well absorbed by crops. However, some factories change the appearance of particles by spraying particles Smoothness, because the slurry is a special viscous slurry, if the ordinary pump is used for spraying, it is easy to cause pipeline blockage, thereby reducing the life of the production equipment
