Description

Technical Field

[0001] The utility model relates to the technical field of polymerized macromolecular water-soluble fertilizer production, in particular to a polymerized macromolecular water-soluble fertilizer production heating and drying device. Background Art

[0002] Polymerized high molecular weight water-soluble fertilizer refers to a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc. that can be completely dissolved in water. It is divided into solid water-soluble fertilizer and liquid water-soluble fertilizer in terms of form, and divided into large-element water-soluble fertilizer, medium-element water-soluble fertilizer, trace element water-soluble fertilizer, amino acid-containing water-soluble fertilizer, humic acid-containing water-soluble fertilizer and organic water-soluble fertilizer in terms of nutrient content. After the fertilizer is produced and granulated, it is easy for the fertilizers to stick to each other, resulting in agglomeration and affecting the fertilization efficiency. Therefore, the compound fertilizer needs to be dried. For this purpose, we provide a heating and drying device for the production of polymerized high molecular weight water-soluble fertilizer.

[0003] However, the existing drying devices often use simple methods to dry fertilizers, which cannot effectively and quickly dry the fertilizers. In addition, the fertilizers cannot be evenly heated and dried during the drying process, which affects the overall drying quality of the fertilizers. Utility Model Content
