Solid chemical fertilizer drying device

Abstract

The invention belongs to the technical field of chemical fertilizer preparing, and particularly discloses a solid chemical fertilizer drying device. The solid chemical fertilizer drying device comprises a drying box internally provided with a hot air structure and a conveying mechanism. The conveying mechanism comprises two conveying rollers and a power source, and a conveying belt is connected between the two conveying rollers and provided with a plurality of V-shaped grooves. The sides, close to the conveying rollers, of the V-shaped grooves are provided with openings. An overturning mechanism is arranged between the two conveying rollers and comprises two rotation shafts. Bent axles are arranged at the middle portions of the rotation shafts, connecting rods are hinged to the bent axles,oscillating bars are hinged to the inner wall of the drying box, the ends, away from the bent axles, of the connecting rods are hinged to the lower ends of the oscillating bars, and support rods arefixedly connected to the middle portions of the connecting rods. Supports are hinged to the upper ends of the support rods. A horizontal movable plate is fixed between the upper ends of the two supports and provided with a plurality of rows of overturning rods. The overturning rods are located under the openings. The lower ends of the oscillating bars are rotationally connected with vibration rollers. A material collecting box is arranged in the drying box. According to the scheme, chemical fertilizer overturning is achieved in the chemical fertilizer conveying process, and the drying effect is good.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, in particular to a solid-state fertilizer drying device. Background technique [0002] Chemical fertilizers refer to chemical fertilizers manufactured or mined by chemical methods, and processed into chemical fertilizers, also known as inorganic fertilizers. In the process of chemical fertilizer production, after granulation, the chemical fertilizers still contain a large amount of water and steam. If they are directly packaged , it will cause the fertilizer to condense into blocks, change color and affect its use value, so the granular fertilizer must be dried through a dryer to increase the strength of the fertilizer particles. At present, steam is generally used in the drum furnace in fertilizer production enterprises. Drying, the drying of chemical fertilizers is achieved through the continuous rotation of the drum furnace, but in actual operation, due to the relatively large p...

[0002] Chemical fertilizers refer to chemical fertilizers manufactured or mined by chemical methods, and processed into chemical fertilizers, also known as inorganic fertilizers. In the process of chemical fertilizer production, after granulation, the chemical fertilizers still contain a large amount of water and steam. If they are directly packaged , it will cause the fertilizer to condense into blocks, change color and affect its use value, so the granular fertilizer must be dried through a dryer to increase the strength of the fertilizer particles. At present, steam is generally used in the drum furnace in fertilizer production enterprises. Drying, the drying of chemical fertilizers is achieved through the continuous rotation of the drum furnace, but in actual operation, due to the relatively large production volume of chemical fertilizers, the drying in the drying furnace is very uneven, which affects the overall effect of chemical fertilizers, and a large amount of chemical fertilizers will The drum furnace itself causes damage which adds to the cost of fertilizer production
