Description
Technical field
The present invention relates to a kind of manufacture method of control release compound fertilizer, belong to technical field of fertilizers.
Background technology
Compound (mixing) fertilizer of domestic production at present mainly is common compound (mixing) fertilizer or coating slowly/controlled releasing fertilizer, the common fertilizer plant recovery of nutrient is low, loss is big, slowly/controlled releasing fertilizer focuses on the control nutrient release rate again, and nutrient shifts out in using at fertilizer what control release compound fertilizer is, controls its loss.Can satisfy farm crop on the one hand and produce nutrient demand, unnecessary nutrient can be fixed in the soil again; Can control the ammonia nitrogen volatilization on the other hand, alleviate Greenhouse effect.Can solve nitrogen, phosphorus runoff and cause body eutrophication, reduce the blue algae bloom probability, reduce widespread pollution from the overuse of fertilizers and pesticides in rural area significantly, reach the raising utilization rate of fertilizer, alleviate the purpose of fertilizer soil, river pollution.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of manufacture method of high tower control release compound fertilizer, the gained control release compound fertilizer is fertilizer nutrient, control nutrient loss fixedly.
Technical scheme of the present invention is as follows:
A kind of high tower control release compound fertilizer manufacture method, be in the urea liquation, to add through the monoammonium phosphate of heating or secondary calcium phosphate, Repone K or vitriolate of tartar, powdery stopping composition, add chemical fertilizer nutrient controlled release agent KS-3 simultaneously, make all addition materials and urea liquation thorough mixing, wherein, the chemical fertilizer nutrient controlled release agent KS-3 of urea liquation 40～65 weight parts, monoammonium phosphate or secondary calcium phosphate 1～40 weight part, Repone K or vitriolate of tartar 10～40 weight parts, stopping composition 1～38 weight part, 5～8 weight parts.Various raw materials are combined into the low temperature eutectic with certain flowing property rapidly under urea melting temperature and mechanical agitation, adopt prilling tower sprinkling pelleting technology to carry out granulation then, when the spray tear drop falls to passing through the airflow of rising in prilling tower, produce cooling and curing, form a kind of compound manure with control fertilizer nutrient loss function.
Described chemical fertilizer nutrient controlled release agent KS-3 is produced by Anhui Province Diyuan Biotechnology CO.,Ltd and sells, chemical fertilizer nutrient controlled release agent KS-3 is that a kind of making an addition to can be controlled the additive that fertilizer nutrient runs off in the common fertilizer, by natural materials is carried out physics and bio-modification, act synergistically with complex material, form huge interpenetrating(polymer)networks, " net is caught " lives chemical fertilizer nutrient, thereby reaches the raising chemical fertilizer utilization ratio, reduce nutrient loss, reduce the purpose of environmental pollution.
Described stopping composition is selected from a kind of in calcium powder, terra alba, ammonium chloride, ammonium sulfate, the clay, but market is buied.
High tower control release compound fertilizer manufacture method, concrete technological operation step is as follows:
1) pours granular urea into receiving opening,, rise to the buffering feed bin through chapelet, enter the urea melting device through the feed spiral, flow into the urine dashpot behind the urea melting, to cat head one-level tempering tank, the urea liquation that enters the one-level tempering tank is 40～65 weight parts through the urea melting pump delivery.
2) monoammonium phosphate or secondary calcium phosphate, Repone K or vitriolate of tartar, the powdery stopping composition is promoted to feed bin via bucket respectively, feed bin bottom design amount scale, measure monoammonium phosphate or secondary calcium phosphate 1～40 weight part respectively, Repone K or vitriolate of tartar 10～40 weight parts, stopping composition 1～38 weight part goes the powder heater heats, material after the heating flow into the powder conveyor, simultaneously, the chemical fertilizer nutrient controlled release agent KS-3 of 5～8 weight parts is joined on the powder conveyor, with monoammonium phosphate or secondary calcium phosphate, Repone K or vitriolate of tartar, the powdery stopping composition is sent into the cat head one-level tempering tank of granulating working procedure together through bucket elevator.
3) urea liquation and monoammonium phosphate or secondary calcium phosphate, Repone K or vitriolate of tartar, powdery stopping composition and chemical fertilizer nutrient controlled release agent KS-3 behind thorough mixing, adopt tablets press to spray in the prilling tower in tempering tank, and naturally cooling solidify to form particle.
The high tower control release compound fertilizer that the inventive method is produced with the main excellent results that common fertilizer, slowly/controlled releasing fertilizer that prior art is produced are compared is:
1. production technique of the present invention is simple, only needs original high tower prilling production equipment and technology simply transformed to get final product.
2 starting material obtain easily, and production cost is low, and the cost performance of equivalence is far above slowly/controlled releasing fertilizer.
3. the production technique of the inventive method can improve the zero pour of melting liquid, makes product particle smooth, mellow and full, and it is light yellow that outward appearance is, and reduces the particle shrinkage cavity, reduces the ammonia loss.And the nitrogenous proportioning height of this product, nutrient is even, moisture content is low, and prevented from caking is convenient to mechanized application.
4. the fixing nutrient of products obtained therefrom, control is run off.This product can provide nutrient continually and steadily in soil, can be more by plant absorbing, the fertilizer nutrient of loss significantly reduces, fertilizer nutrient more than needed remains fixed in the soil, can for following season plant continue to absorb.And slowly/controlled releasing fertilizer focuses on nutrient release rate, and non-control is run off.
5. the environmental protection of the inventive method products obtained therefrom, natural degradation, long-term application can be improved soil physico-chemical characteristic, improves soil fertilizer and water retention capacity.
6. the products obtained therefrom sustained-release fertilizer is as the disposable use of base manure, and the centre does not need to topdress, and the peasant saves time, laborsaving, saves the fertilizer input simultaneously.
