Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer granulation technology, and in particular to a granulation device for the production and processing of chelated fertilizers. Background Technology
[0002] In agricultural production, chelated fertilizers have become an important choice for modern agricultural fertilization due to their ability to effectively improve the absorption and utilization rate of micronutrients by crops and reduce nutrient loss. Granulation equipment used in the production and processing of chelated fertilizers, as key equipment for processing raw materials into granular finished products, directly affects the product quality, production efficiency, and application effects of chelated fertilizers. Through granulation, chelated fertilizers not only become easier to store, transport, and apply, but also allow for adjustments to particle size and slow-release properties according to the needs of different crops and soils, further enhancing the comprehensive utilization value of fertilizers and playing an indispensable role in large-scale agricultural production and precision fertilization systems.
[0003] Currently, most existing chelated fertilizer granulation equipment uses traditional extrusion or disc granulation methods. Extrusion granulation, which forms granules through die holes, suffers from uneven particle hardness and excessive powder, and is prone to die clogging due to high raw material viscosity, affecting continuous production. Disc granulation relies on rotational agglomeration, which is highly sensitive to raw material moisture content; improper moisture can lead to excessively large agglomerates or low forming rate, and uneven particle size requires extensive subsequent screening, increasing costs. Furthermore, existing equipment does not adequately protect chelated components; excessive mechanical shearing force or improper temperature control can damage the chelate structure and reduce the content of effective ingredients. Therefore, to address the problems of unstable particle quality, low production efficiency, and easy damage to effective ingredients in existing equipment, a new granulation device for chelated fertilizer production is proposed to solve these problems.

[0032] Working principle: When using this equipment, the material is first put into the feed hopper 3 at the top of the granulation barrel 1. Then, the motor 2 14 is started to drive the crushing shaft 15 to rotate, so that the crushing teeth 17 on the side wall of the crushing shaft 15 rotate in the feed pipe 2. At the same time, the clumps of material are broken up by the cooperation of the tooth edge 16 and the crushing teeth 17, so that the material enters the lower granulation barrel 1. At this time, the motor 3 18 is started to drive the rotating shaft 2 19 to rotate, and then drive the auger blade 20 to rotate to push the material to the back of the die plate 4. At the same time, the motor 1 10 is started to drive the rotating shaft 9 to rotate, so that the blade 8 on the side wall of the rotating shaft 9 rotates. At the same time, under the extrusion of the auger inside the granulation barrel 1, the material is squeezed out from the die plate 4 and granulated by the cooperation of the blade 8. The cut material then falls into the receiving barrel 23.
[0033] Meanwhile, to facilitate the replacement of templates of different sizes, the bottom plate 11 at the bottom of motor 10 and the fixing rod 12 on its side wall slide backward in the sliding groove 13 on the side wall of granulation barrel 1, so that the blade 8 and motor 10 move backward. At the same time, by rotating the die plate 4 and the positioning block 6 and sealing strip 7 on the side wall of granulation barrel 1, the sealing strip 7 on the die plate 4 slides out of the positioning block 6 in granulation barrel 1, and the sealing ring 5 on the side wall of the die plate 4 is pulled out from inside the granulation barrel 1, thus completing the function of disassembling the die plate 4.
