Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compound fertilizers, in particular to a particle drying device used for compound fertilizer production. Background Art
[0002] Compound fertilizer refers to a chemical fertilizer containing two or more nutrients including nitrogen, phosphorus and potassium. 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. When processing fertilizers, a drying device is required. However, when drying fertilizers, some existing fertilizer drying devices usually pour the fertilizer onto a conveyor belt and then dry the fertilizer through a heating device to reduce the moisture content in the fertilizer. Since fertilizers have a certain viscosity when wet, when the moisture in the fertilizers is dried, the fertilizer particles tend to stick together, causing the fertilizer to clump.
[0003] Patent application number CN221122907U discloses a drying device for compound fertilizer production, comprising a drying box, a feed port provided at one end of the top of the drying box, a first heating plate provided at the top of the drying box, an array of through holes provided at the top of the drying box, the through holes penetrating the first heating plate, a spoiler provided in the through holes, an active roller and a driven roller provided at both ends of the drying box, the active roller and the driven roller being connected by a conveyor belt, the lower end of the spoiler abutting the conveyor belt, a second heating plate being installed between the active roller and the driven roller. A spoiler abutting the conveyor belt is provided at the top of the drying box, and in the process of the fertilizer being transported by the transmission belt, the fertilizer on the conveyor belt continuously collides with the spoiler, causing the fertilizer on the conveyor belt to be continuously disturbed and dispersed, thereby preventing the fertilizer particles from sticking to each other during the drying process, causing the fertilizer to agglomerate, thereby improving the fertilizer production efficiency and ensuring the fertilizer drying effect.
[0004] However, the efficiency of the compound fertilizer drying device disclosed above is average, the compound fertilizer cannot be fully stirred, and it is easy to clump and stick after long-term use. In addition, the degree of automation is average, and there is a lack of an automatic unloading structure. Utility Model Content
