Description
Technical field
The invention belongs to a kind of compound fertilizer production technology.
Background technology
The fertilizer material used for agriculture that is absolutely necessary in agriculture production, present existing fertilizer is divided into mineral manure and organic fertilizer, mineral manure is mineral substance or inorganic chemistry reacts the fertilizer that processes, organic fertilizer is the fertilizer that the waste in natural humus matter, livestock and poultry manure, industrial production or the people's life processes, and the production technology of mineral manure, organic fertilizer is very ripe.
In China, for many years because long-term application chemical fertilizer, the fertilizer deficiency, all kinds of nutrients ratios imbalances cause farmland ecological environment, soil physical and chemical property and soil microflora to be subjected in various degree destruction, have influenced the safety of agricultural-food to a certain extent.The life-time service of chemical fertilizer or use the improper problem that may cause and have: farmland quality descends, and output descends, and quality descends, environmental pollution.Western countries' bio-feritlizers such as the U.S. are near 50% of the total consumption of fertilizer.China's organic fertilizer production is ascendant trend year after year, and market outlook are wide, becomes the new industry of a new round.State Council clearly proposes to promote " ecological agriculture " in ten big countermeasures of China's ecological environmental protection.In order to develop eco-agriculture, Development and Production is pollution-free " green food ", and the fertilizer practice in the agriculture production must be reformed, and promptly rational use of chemical fertilizer walk the development of organic-inorganic compounding application, and organic fertilizer should be advocated energetically and be developed more.
At present, China's organic fertilizer raw materials for production mainly comprise tens kinds of poultry manure, mud, stalk, the peat composed of rotten mosses, bone meal, grouts etc.These raw fibre cellulose content height, self viscosity are poor, it is big to contain moisture, cause the granulation difficulty, and the particle roundness is poor.Because product moisture content causes the storage time short greatly, the fertilizer of production will be used in very short time, otherwise can harden; The particle roundness is poor, from not accepted by the user in appearance, has limited the production and selling of fertilizer to a great extent; Production capacity is low, the cost height.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production technique of making ball rate height, outward appearance rounding, containing the low organic-inorganic complex fertilizer of moisture.
For solving the problems of the technologies described above, the present invention by the following technical solutions: production process of organic-inorganic compound fertilizer comprises the following steps:
A, the organic raw material fermentative processing is become ecological organic fertilier, add crusher with inorganic raw material;
B, organic and inorganic raw material enter after fragmentation in the rotary drum granulator, by mending entry, steam, the auxiliary granulation of urine;
The material that c, rotary drum granulator come out enters granulating disc again, continues granulation;
D, then the material after the granulation is carried out two-stage drying, material after the granulation enters into the 1# drying machine and carries out drying, dried material is sent into the scalping sieve and is gone fine powder, other material to enter 2# drying machine continuation drying, and the material behind two-stage drying is sent into the cooler cooling;
E, cooled material enter big grain sieve, and macrobead is screened out;
F, finished product and part fine powder enter the finished product sieve and continue screening, and the finished product that sifts out can be packed after anti-caking is handled and dispatch from the factory.
Inorganic raw material described in the step a is phosphorus ammonium, general calcium, urea, Repone K;
Two sections drying processes in the steps d, bake out temperature is controlled at 60～80 ℃.
Macrobead enters tablets press among the step e after fragmentation.
Fines returns tablets press among the step f.
Adopt above technical scheme to give full play to the advantage of two kinds of prilling process, the solution product appearance is of poor quality, granulation contains the high problem of moisture.Because rotary drum granulator is long cylindrical shell; the steam, the urine that add have competent sprinkling space, and powder granulous base fertilizer is by means of water, steam, the molten adhesive aggregation granulating of fertilizer, with the rotation of tablets press; material is at the granulating of progressively reuniting in the discharge end process of flowing, and the granulation amount of water is few.The disk granulation makes the disposable balling ratio height of particle, and the returning charge multiple is little, and operation is directly perceived, because its rotating speed is higher relatively, rounding particle is not had the effect of polishing, rounding, the ropy problem of solution organic-inorganic composite fertilizer product appearance.
Production technique production capacity of the present invention obviously increases, the production technique of taking drum granulating and disk granulation to be in series, utilization replenishes required moisture and the heat of granulation in rotary drum granulator, in rotary drum granulator, realize the balling ratio more than 50%, owing to realized the heat granulation, the moisture branch of granulation material obviously reduces; Need not add water in granulating disc, the burden that makes granulating disc bear granulation reduces greatly, and granulating disc mainly is responsible for the effect of polishing, rounding.Because this tandem process has solved two big defectives of disk granulation, the oven dry load is lower, so the production capacity of this technology is higher.
Production process of organic-inorganic compound fertilizer of the present invention; granulating working procedure adopts drum granulating to add the disk granulation; in rotary drum granulator, mend required moisture and the heat of granulation; in granulating disc, improve balling ratio, improve the particle roundness; take two-stage granulation tandem process to make the granulation balling ratio improve 20%, give full play to the advantage of two kinds of prilling process again, the product water content is low; solve the second-rate problem of organic and inorganic fertilizer product appearance, improve production capacity.
