Dehumidification equipment for inorganic fertilizer manufacturing and heat dissipation method thereof

Abstract

The invention belongs to the technical field of inorganic fertilizer manufacturing, particularly relates to dehumidification equipment for inorganic fertilizer manufacturing and a heat dissipation method of the dehumidification equipment, and aims to solve the problem that a dry output environment needs to be ensured during granulation in existing inorganic fertilizer production, and adopts the following scheme that the dehumidification equipment comprises a bottom plate, and a granulator body and a supporting column are arranged at the two ends of the outer wall of the top end of the bottom plate; a low-temperature cover is fixedly mounted between the granulating machine body and the supporting column, and a discharging channel is arranged at the outlet end of the granulating machine body. The temperature in a low-temperature cover is always 25 DEG C, and meanwhile, a negative pressure fan and a motor work, so that mixed air in the low-temperature cover sequentially passes through a molecular sieve drying frame, a montmorillonite drying frame, an anhydrous calcium chloride drying frame, a fiber drying frame and a silica gel drying frame from outside to inside; moisture, dust, harmful gas and the like in the mixed air are filtered and adsorbed in a heavy-to-heavy manner, so that the inorganic fertilizer discharged from the discharging channel is prevented from absorbing moisture and being decomposed, the production qualification rate of the inorganic fertilizer is improved, and the service life of the transportation mechanism is prolonged.

Description

technical field [0001] The invention relates to the technical field of inorganic fertilizer manufacturing, in particular to a dehumidification device for inorganic fertilizer manufacturing and a heat dissipation method thereof. Background technique [0002] Chemical fertilizers, also known as inorganic fertilizers, are fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements required for the growth of crops; chemical fertilizers can be divided into physiologically acidic fertilizers, physiologically alkaline fertilizers, and physiologically alkaline fertilizers according to their chemical properties. Fertilizers, physiological neutral fertilizers, common nitrogen fertilizers, phosphate fertilizers, potash fertilizers, micro-fertilizers, compound fertilizers, etc., can also be divided into quick-acting fertilizers, slow-acting fertilizers, long-acting fertilizers, soil fertilizers, and foliar fertilizers according to their performanc...

AI Technical Summary

Problems solved by technology

[0004] When producing and granulating inorganic fertilizers, it is necessary to ensure a dry output environment, because inorganic fertilizers can easily absorb moisture in the air, causing inorganic fertilizers to deliquesce and agglomerate. Nitrogen fertilizers are volatile and reduce fertilizer efficiency, which not only reduces the production pass rate of inorganic fertilizers, but also easily corrodes the conveying mechanism in the long run, so a dehumidification equipment for inorganic fertilizer manufacturing is needed to solve the above problems
