Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer processing, and more specifically, particularly relates to a compound fertilizer particle cooling device. Background Art

[0002] Compound fertilizer refers to a fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops. In the production process of compound fertilizer, after the fertilizer particles are made, they need to be dried. After drying, the temperature of the compound fertilizer particles is relatively high and needs to be cooled. Therefore, a cooling device is needed to cool the compound fertilizer particles.

[0003] However, there are various types of cooling devices in the prior art. For example, utility model patent CN220472002U relates to a compound fertilizer particle cooling device, which can effectively control the feeding speed and feeding amount of compound fertilizer particles, thereby effectively ensuring the cooling efficiency and cooling effect of the compound fertilizer particles, effectively ensuring the use effect of the equipment, and avoiding the situation where the compound fertilizer particles are fed too quickly and affect the cooling effect.

[0004] Although the cooling device can control the feeding speed and feeding amount, and conduct air cooling through the guided conveying of the guide plate, the particles in the device fall directly, and the time they stay in the air cooling area generated by the fan is short, the cooling effect is poor, and the cooling operation is not thorough and comprehensive enough. In order to avoid this phenomenon, it is very necessary to design a compound fertilizer particle cooling device. Utility Model Content

Compared with direct falling, the longer spiral slide increases the residence time of the high-temperature particles in the water-cooling area, and the cooling effect is improved, making the cooling operation of the compound fertilizer particles more thorough and comprehensive.
