Processor and processing method for agricultural chemical fertilizer hardened with damp

Abstract

The invention relates to the technical field of agricultural chemical fertilizer hardened with damp, in particular to a processor for agricultural chemical fertilizer hardened with damp. The processorcomprises a box. A feeding hopper penetrates through the top of the box. A smashing assembly is arranged at the portion, below the feeding hopper, of the box. A screening assembly is arranged at theportion, below the smashing assembly, of the box. The screening assembly is connected with the screening assembly through a transmission assembly. A dehumidification assembly is arranged at the portion, below the screening assembly, of the box. The dehumidification assembly is in transmission connection with the smashing assembly through a drive assembly. Agricultural chemical fertilizer hardenedwith damp is smashed through the smashing assembly, then, the fertilizer enters the screening assembly for secondary screening processing, unsmashed or large-particle fertilizer is screened out, the transmission assembly is arranged for supplying transmission power to the screening assembly, the screening effect of the screening assembly is improved, the dehumidification assembly is used for performing dehydration and dehumidification on the screened agricultural chemical fertilizer, and the agricultural chemical fertilizer hardened with damp is recycled.

Description

technical field [0001] The invention relates to the technical field of damp-hardened agricultural chemical fertilizers, in particular to a processor and a treatment method for damp-hardened agricultural chemical fertilizers. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers, fertilizers made by chemical and (or) physical methods containing one or several nutrient elements needed for the growth of crops, also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc.; They have the following common characteristics: simple ingredients, high nutrient content; quick fertilizer effect, strong fertilizer; some fertilizers have acid-base reaction; generally do not contain organic matter, and have no effect of improving soil and fertilizing. The macronutrient nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop gr...

Problems solved by technology

[0003] When agricultural chemical fertilizers are stored and placed, the surrounding environment should be kept dry, well-ventilated, and the temperature is below 20 degrees; There will be a phenomenon of moisture compaction among the raw materials of chemical fertilizer granules. Since the raw materials of chemical fertilizers are generally unable to effectively isolate the air when they are piled up and stored, the fertilizers are easy to be damp and hardened into lumps, and those that are less damp are irregular lumps. The hardness of the fertilizer depends on the condition of moisture, the more severe the moisture, the higher the hardness of the agglomeration; in order to solve the phenomenon of moisture hardening when the fertilizer is stored, a moisture-proof board is usually installed at the bottom when the fertilizer is stored, but this method has little effect; If the moisture content in the fertilizer cannot be reduced, house agglomerated materials can also be added to reduce the direct contact between particles, which will greatly increase its storage cost

[0004] At present, the treatment methods for the chemical fertilizers that have been hardened by moisture are generally crushed, and the treatment methods include extrusion, impact, shearing, and grinding; Splitting, crushing, impact crushing and grinding; at present, when the chemical raw materials that are damp and hardened are crushed, they generally adopt impact crushing or grinding. During the crushing process, there is a problem that the crushing treatment of chemical fertilizers is not sufficient. Since the raw materials of the fertilizers themselves are damp, the moisture inside the fertilizers cannot be effectively removed when crushing them, and the wet and hardened fertilizer raw materials are broken after the crushing process. Some fertilizer raw materials are easy to remain on the device, and the equipment needs to be cleaned. There are many steps and troublesome operations when cleaning the equipment.
