Abstract
The invention discloses a preparation technology of zeolite nitrate fertilizer and belongs to the fertilizer industry. The preparation technology comprises the following steps of: carrying out neutralization reaction, evaporating and dehydrating, stirring and mixing, pelletizing and packaging separately. According to the preparation technology disclosed by the invention, the design is novel, the process is advanced, the method is special and the use is extensive. By adopting the preparation technology, not only the nitrate fertilizer loss problem with the water is solved, but also the release supply time of the nitrate fertilizer in the soil and the water is prolonged. Meanwhile, the operation is easy, the production cost is low, and the practicability and the generalization performance are great.
Description
Technical field
What the present invention relates to is the fertile technology of preparing of a kind of nitric acid zeolite, belongs to fertilizer industry.
Background technology
At present, nitric acid fertilizer applies and exists the drawback that outflows with water in soil.
Summary of the invention
The invention provides the fertile technology of preparing of a kind of nitric acid zeolite, can overcome above-mentioned drawback.
The present invention realizes by the following technical solutions: a kind of technology of preparing of nitric acid zeolite fertilizer, it comprises neutralization reaction, dehydration by evaporation, mix, granulation, packing is characterized in that: the fertile technology of preparing of nitric acid zeolite, it is that 5-85% four water-calcium nitrate solution is added in the stainless steel neutralization reaction groove of diameter 4000 * 3000mm, then adds the ammonium nitrate solution reaction of 3-8% to generate calcium ammonium nitrate solution; Calcium ammonium nitrate solution is squeezed in the 100m3 stainless steel evaporators with stainless steel ammonium calcium liquid pump, and then heating reaches 150-180 ℃ and carries out dehydration by evaporation, and in the stainless steel storagetank of input diameter 6000 * 6000mm; 100-400 order zeolite powder, 1-80% fine particle calcium carbonate powder, the calcium ammonium nitrate solution of 1-80% are squeezed in the stainless steel mixing tank with Stainless Steel Pump respectively and mixed; The mixture that stirs is squeezed in 3000 type stainless steel granulating discs with stainless steel centrifugal pump carried out granulation, cause the 0.1-10mm particle; The particle of moulding is flowed into the amount packing warehouse-in that the component machine is divided into the 1-50 kilogram.
Advantage of the present invention and positively effect:
Modern design, technique is advanced, and method is unique, and purposes is wide.Not only solve the problem that outflows with water of nitric acid fertilizer, and extended the release supply time of nitric acid fertilizer in soil, in water.The fertile technology of preparing of this nitric acid zeolite is easy to operate, and production cost is low, has practicality, generalization.
