Description
Technical field
The invention belongs to agrochemical technical field, be specifically related to a kind of couple of zinc enzyme zinc ammonium compound fertilizer preparation technology.
Background technology
The demand characteristics to nutrition according to soil fertility and crop growth period, the various compound manure efficient, environment-friendly type of Development and Production are the general trends of world today's Growth of Chemical Fertilizer Industry, being the major objective of fertilizer variety structural adjustment, is also the general orientation of modern agricultural development.For fertilizer enterprise, seize the opportunity, according to the nutrient uptake feature of different crops, develop targetedly, study, produce various Different Nutrients, dissimilar compound manure, with meet China's modern agriculture to different soils, Different Crop, different growing stages plant to fertilizer demand, become trend of the times.
At present, Chinese compound manure Market Situation more complicated.On the one hand, along with the development of agriculture production, peasant more notices that reducing labor force boosts productivity, and uses compound manure once to apply by multiple nutrient, and saving of work and time, has facilitated peasant, thereby more welcome.Because Chinese Government continues to increase the supporting dynamics to agriculture production, every policy of supporting agriculture is constantly put into effect, domestic agricultural byproducts price is continuous rise in recent years, peasant's per capita income steady growth, the enthusiasm that peasant increases input in agricultural is unprecedentedly surging, and it is also constantly increased the purchasing power of basic chemical fertilizer and compound manure.Add the gap between China composite fertilizer industry and international most advanced level, and the impact of import fertilizer product to domestic market, make the fertilizer enterprise of China be faced with stern challenge.Particularly face the new situations after China joined WTO, for high content of technology, good product quality, the fertilizer enterprise that marketing competition ability is strong, it is large that its produce market becomes, the possibility that existing goes abroad enters world market.And concerning the fertilizer enterprise of those shortage competitive capacity, not only product does not enter world market, domestic market also may be tied up by similar products at home and abroad.Along with country payes attention to environment protection, develop environment friendly and pollution-free fertilizer imperative simultaneously.Company gives full play to the intrinsic advantage of the fat device of existing compound under these circumstances, 100,000 tons/year of two enzyme zinc ammonium compound fertilizer projects of reconstruction are proposed, further promote, optimize the product structure of enterprise, start enterprise's new growth engines, the economic scale of enterprise's superior product is further rationalized, expanding the occupation rate of composite fertilizer on market, is very necessary, very timely.Its manufacturing technology steps is, the materials such as sulphur ammonium stopping composition zinc fertilizer of powdery enter pulverizer and pulverize, enter tablets press in slip mixing balling-up afterwards again, and yeast powder enters the two complexing balling-up of mixing of materials of tablets press and powdery after reacting through watery fusion with selenium fertilizer and urea.Through drying, cooling, screening, cooling, sieve, be packaged into stockyard and wait for delivery.The shortcoming of this handicraft product is to melt soon, bad production, and also unsuitable prolonged preservation, brings very large difficulty to the manufacturing.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of couple of zinc enzyme zinc ammonium compound fertilizer preparation technology, for the production of different content multienzyme, zinc, selenium composite fertilizer material, enzyme in polypeptide can promote Crop, improve the utilization ratio of fertilizer, make the utilization of nitrogen element more reasonable, melting in use fast plant absorbs just fast, so plant-growth is all right, its micro-controlled release fertilizer efficiency evenly discharges, have melt fast, the feature that fertilizer efficiency evenly discharges, improves the yield and quality, fertilizer efficiency is long-term.
To achieve these goals, the technical solution used in the present invention is: a kind of couple of zinc enzyme zinc ammonium compound fertilizer preparation technology, includes following steps:
One, by electronics feeding machine raw materials weighing, the urea 30%～35% of N >=46%, yeast powder 2.5%～3.75%, selenium fertilizer 0.1%～0.15%, zinc fertilizer 0.1%～0.15 after pulverizer is pulverized, mixes in tempering tank, the temperature of tempering tank is 100～125 degree, and stirring velocity is 15～20 revs/min;
Two, yeast powder, zinc fertilizer, selenium fertilizer and urea are pressed 2.5: 0.1; 0.1: 300 ratio, adds in reactor and reacts through watery fusion, and melt temperature is 110～130 ℃;
Three, the material mixing of step 1 is sprayed in tablets press with together with watery fusion material in reactor, with the ammonium sulfate 40%～45% of pulverizing by N >=20% of Belt Conveying, ground dolomite, the granulation together of wilkinite 20%～25% mixture, mix two complexing balling-up;
Four, the material of process granulation enters in single dryer and dries, and the condition of oven dry is 95～125 ℃;
Five, the material after drying enters and in two coolers, carries out coolingly, and cooling rear temperature of charge is not higher than 10～15 ℃;
Six, cooled material once sieves with 3.0～5.0 object sieves, and the particle below 3.0 orders returns to granulation again in tablets press, and particles more than 5.0 orders returns in pulverizer and again pulverizes;
Seven, the material that entered once screening obtains sieve with 2.5～4.5 orders again and carries out regrading, and the particle below 2.5 orders returns to granulation again in tablets press, and the material sieving through regrading can be packed.
The invention has the beneficial effects as follows:
Utilization of the present invention and thiamines, zinc fertilizer can form the feature of eutectic point compound and stopping composition combination; by urea and yeast powder, the fertile NPK molten slurry that generates good fluidity that reacts of selenium; this slip becomes particle by the nozzle specially used compound mixed fertilizer granulating machine after fixing that sprays into, thereby obtain, Nutrient distribution is even, the good composite fertilizer of particle proterties.Key point of the present invention is to prepare the melting charge slurry of good fluidity, the temperature of tempering tank, stirring velocity, the residence time, raw and auxiliary material are used, slip liquid-solid ratio is the main control parameters of this technological process, parameter control well to contribute to reduce slip viscosity, reduce biuret, guarantee its mobility, reduce side reaction, reduce ammonia and damage.
