Description

Technical Field

[0001] The utility model specifically relates to a humic acid silicon synergistic fertilizer particle drying device, belonging to the technical field of drying equipment. Background Art

[0002] Humic acid silicon fertilizer is a composite water-soluble fertilizer made from silicon fertilizer raw materials and humic acid raw materials. It has rapid and long-lasting slow-release effects, small dosage and good effect. It can stimulate plant growth while supplementing silicon elements, activate phosphorus in the soil, and regulate the balanced absorption of elements by crops.

[0003] Existing humic acid silicon fertilizers need to be dried after being made into granules to stabilize the structural strength of the fertilizer granules and facilitate subsequent transportation and storage and other disposal methods. For example, a Chinese invention patent document, publication number CN117588918A, records a fertilizer processing and drying device, which relates to the field of fertilizer processing technology. Granular fertilizer is spread on the upper surface of a drying plate, and when the drying plate is driven to vibrate, the granular fertilizer slowly slides from the top to the bottom along the upper surface of the drying plate, and a blower mechanism is arranged from the bottom of the drying plate along the sliding direction of the fertilizer. At the same time, through the arrangement of exhaust pipe one, exhaust pipe two, exhaust pipe three, exhaust pipe four and exhaust pipe five, gradient drying is achieved during drying, thereby improving the drying effect and energy utilization rate.

[0004] However, in the above-mentioned documents, undried fertilizer particles are transported by vibration. Although the fertilizer particles can be evenly fed and spread during transportation, which is conducive to drying, the fertilizer particles themselves have a certain humidity. When vibrated, the fertilizer particles will deform or even spread, which greatly affects the quality of the finished fertilizer product. Utility Model Content
