Abstract
The invention provides a method for producing a diammonium phosphate product added with trace elements, which relates to a phosphate fertilizer, and also relates to a trace element fertilizer. One type or more types of soluble salts containing iodine, cobalt, selenium, zinc, copper, ferrum, manganese and boron are added into the diammonium phosphate product, mixed with a diammonium phosphate slurry, and then granulated and dried by a conventional technology. The soluble salts containing iodine, cobalt, selenium, zinc, copper, ferrum, manganese and boron can be respectively sodium iodide or potassium iodide, cobalt oxide, selenium oxide, zinc oxide, copper sulfate, ferric sulfate or ferrous sulfate, manganese sulfate and borax. The proportion of trace elements in the product is 1%-3%, and the proportion of total nutrient content is not less than 64%. The invention can produce different diammonium phosphate products containing different nutrient contents of trace elements, has good economical benefit, satisfies the demand of fertilizer markets, and promotes the development of agricultural production.
Description
Technical field
The present invention relates to phosphate fertilizer, also relate to trace element fertilizer, specifically, relate to the working method of the ammophos that is added with trace element.
Background technology
As everyone knows, ammophos is a nitro phosphor complex, can two kinds of important nutritive ingredients be provided to farm crop.But the nutritive ingredient that crop needs is far above two kinds in nitrogen phosphorus, and many nutritive ingredients are relevant with trace element.Agricultural development be unable to do without the fertilizer with multiple nutritional components.Just because of this; People have researched and developed many trace element fertilizers, for example Chinese patent No. 92110214.3 " compound trace element liquid fertilizer ", No. 98111578.0 " various trace elements formula fertilizers ", 02113524.X number " compound trace element fertilizer enriched in selenium ", No. 200410029779.6 " organic chelated Medium Trace Element Fertilizer technology ", No. 200680052549.9 " mineral manure that comprise the biological processing of trace element " etc.The world market is very big to the demand of trace element fertilizer, especially adds the product that contains iodine, cobalt, selenium, zinc, copper, iron, manganese element.Therefore, for meeting the market requirement,, need the trace element fertilizer product innovation of being badly in need of in the continuation developing target market also in order to realize the variation of product.
Summary of the invention
The object of the invention just is to provide the method for producing the diammonium phosphate product that is added with trace element, with this method production can meeting the market requirement the trace element fertilizer new variety.
The contriver is according to the psychological need of different soils, different plants, the difference of nutrition nutriment in a fertilizer; Investigation according to domestic and international market; Develop the granular monoammonium phosphate product innovation that is added with trace element; Its working method is in diammonium phosphate product, to add in proportion by in the soluble salt that contains iodine, cobalt, selenium, zinc, copper, iron, manganese, boron one or more, and mixes with diammonium phosphate slurry, processes through conventional technology granulation, drying; Concrete working method is:
The first step, one or more micro-soluble salts that need are added add feed bin respectively;
Second step, control its amount from the trace element that each feed bin gets off through push-pull valve separately, send into trench respectively after metering by rotary conveyor separately, be flushed to sloptank with tail vapour washing tower washing lotion again, process mixed solution;
The 3rd step, with the sloptank pump mixed solution is squeezed into pre-neutralization reactive tank and pipe reaction feeding trough, with the reaction mass uniform mixing, obtain being mixed with the diammonium phosphate slurry of trace element;
The 4th step, slip is squeezed into tablets press spray granulating together with transferpump, obtain being added with the diammonium phosphate pellet of trace element;
The 5th step, at last according to common process, pellet is used warm air drying, obtain being added with the diammonium phosphate product of trace element.
The above-mentioned soluble salt that contains iodine, cobalt, selenium, zinc, copper, iron, manganese, boron is respectively Soiodin or potassiumiodide, powder blue, selenium oxide, zinc oxide, copper sulfate, ferric sulfate or ferrous sulfate, manganous sulfate, borax.
The metering of above-mentioned trace element is that each micro-mass percent of adding is 0.05%～1% in the per 1 ton of product of control; Method of calculation are according to the amount that contains trace element in the predetermined prod, calculate the amount (pure) of the soluble salt of per 1 ton of needed consumption of product, calculate the required total mass that adds the raw material of trace element by product production per hour again.
Each salt added a feed bin when soluble salt of above-mentioned trace element got into feed bin.
The washing lotion of above-mentioned washing tower is the washing lotion of tail vapour washing tower washing lotion sealing groove riser.
The amount that the diammonium phosphate product that is added with trace element of aforesaid method production contains trace element is 1%～3%, and the total nutrient of product is not less than 64%.
Production provided by the invention is added with the method for the diammonium phosphate product of trace element, can produce the diammonium phosphate series product that contain different micro-element nutrition compositions, satisfies the needs in chemical fertilizer market, promotes the development of agriculture prodn.
Description of drawings
Accompanying drawing is the process flow diagram of the inventive method.Among the figure, 1 is sloptank, and 2 is rotary conveyor, and 3 are the washing liquid pump, and 4 for trace element adds feed bin, and 5 be transferpump, and 6 be trench, and 7 be to wash the receiving tank pump, and 8 is the close trough washery liquid of liquid, and 9 claim for belt.
Embodiment
Embodiment: produce boracic 0.2% and the diammonium phosphate product that contains zinc 0.5%
Calculate the amount of required borax: borax molecular formula: Na
2B
4O
7.10H
2O, molecular weight: 381.37, nucleidic mass 10.8, borax purity 99.5%, boracic 1000 * 10.8 * 4/381.37=113.275 * 99.5%=117.709g among every 1kg.The predetermined prod boron-containing quantity is 0.2%, and boron-containing quantity is 1000 * 0.2%=2g in then every 1kg product, is converted into 2/10.8*4/381.37=17.65g, and the borax that needs in every 1t product to add is 17.6 5/99.5%=17.74g.
If every 1h produces 60 tons of products, then total add-on is: 60 * 17.74=1064.44kg, the add-on of every 1h is: 1064.44kg/h.
Calculate required zinc oxide amount: being scheduled to add the zinc oxide amount is 0.2%, then adds the zinc oxide amount and is: 1 * 0.2% * (65/81)=2.4869kg/t product; By every 60t/h product, then adding the zinc oxide amount is 2.4869 * 60=149.214kg/h.
Borax and zinc oxide are added two feed bin the insides respectively, open conveyor, open the part push-pull valve, regulate aperture, see that system was in normally when two belt read numbers were respectively 1064.44kg/h and 149.214kg/h; Two kinds of salt are added trench; Washing lotion through the sealing groove riser that overflow by the tail vapour washing tower of production equipment is rushed in sloptank; Start the sloptank pump then and squeeze into pre-neutralization groove and tubular reactor feeding trough; Spray into the tablets press spray granulating again, use warm air drying at last, obtain boracic 0.2% and the diammonium phosphate product that contains zinc 0.5%.Sampling analysis in the process, in product content qualified till.Produce through this mode, both the diammonium phosphate product that contains the zinc boracic was provided, can create higher economic benefit again to market.
