Abstract
Silicophosphate fertilizer and manufacture method thereof.Yellow phosphorus furnace slag and fused(calcium magnesium)phosphate work in-process mixed by 1: 0.05-20, dry under 600-800 ℃ temperature, when the water content of batching less than 1% the time, it is levigate, promptly get product.The content of effective Vanadium Pentoxide in FLAKES is not less than 2% in the product, and soluble silica is not less than 14%.Provided by the invention method is simple, has good social benefit and economic benefit with the product of this manufactured.
Description
The present invention relates to a kind of is that raw material is allocated silicophosphate fertilizer and the corresponding method of manufacture that the fused(calcium magnesium)phosphate work in-process are made into the yellow phosphorus furnace slag.
Secular agricultural production practice shows, phosphorus is one of three kinds of main nutrient elements of crop growth, and people recognize progressively that also silicon is a kind of important element in the soil equally, and it can increase the disease resistance of farm crop, prevent that plant from draping over one's shoulders leaf, diseases such as cane weakness and grouting deficiency.To absorb the more paddy rice of silicate amount is example, 1 kilogram of paddy of every production, and the silicon-dioxide that paddy rice absorbs reaches 0.1 kilogram, is equivalent to the twice of nitrogen, phosphorus, potassium absorbed dose, and still along with the increase of amount of application of nitrogen fertilizer, people often only note devoting exclusive attention to output continuous cropping every year; Straw often is used to papermaking again and makes fuel, can not fully go back the field, and the silicon in the soil is lost in a large number.Therefore caused the silicon nitrogen serious disproportion in the soil (normally than be 3: 1).Because the deficiency of the silicone content in the soil, paddy rice drapes over one's shoulders leaf, and basistipe on the ground rots, and shows foxiness on the rice husk, stage of maturity blade premature dead, and paddy grouting is not enough, and output just descends significantly.
Yellow phosphorus furnace slag is the waste residue in producing, can be quite high but contain by the silica volume of plant absorbing, be used as the cement raw material except that a small amount of at present, and most abandoneds cause the waste of resource, again contaminate environment.The yellow phosphorus furnace slag amount in Yunnan Province, be ten thousand tons of 8-10 existing every year, and project under construction will reach ten thousand tons of 80-110 after going into operation, and it is fully used, and this is a problem that urgency is to be solved.
Purpose of the present invention, being to provide a kind of is that raw material is allocated the fused(calcium magnesium)phosphate work in-process into, the silicophosphate fertilizer that produces with the yellow phosphorus furnace slag; Provide a kind of simple and easy to do manufacture method, for the processing and utilizing of yellow phosphorus furnace slag and the source of silicophosphate fertilizer raw material opening up new way.
Content of the present invention is, is raw material with yellow phosphorus furnace slag and fused(calcium magnesium)phosphate work in-process, and yellow phosphorus furnace slag and fused(calcium magnesium)phosphate work in-process are by 1: the mixed of 0.05-20 can obtain silicophosphate fertilizer after drying is levigate.Drying temperature is 600-800 ℃ (or drying under the daylight), and it is levigate less than 1% the time when the water content of batching, product fineness is to be 80% by 80 eye mesh screens.Zhi Bei silicophosphate fertilizer product contains effective Vanadium Pentoxide in FLAKES and soluble silica in this way, and wherein effectively the content of Vanadium Pentoxide in FLAKES is not less than 2%, and soluble silica is not less than 14%, also contains various plants nutritive elements such as calcium magnesium.
Production Flow Chart synoptic diagram of the present invention sees accompanying drawing for details.
Major advantage of the present invention, the method that is is simple, processing ease; the silicophosphate fertilizer of making had in this way both solved the problem that soil lacks silicon, made again the yellow phosphorus furnace slag of enormous amount obtain effective utilization; turn waste into wealth, be conducive to environmental protection, two get real the genus at one stroke. The present invention has good Social benefit and economic benefit, and product has been made spread in the Ben Sheng farmland, makes grain, beans, fruit etc. obtain the volume increase of different amplitudes, also finds a good sale in now the provinces such as Henan, Anhui, Shandong, and supply falls short of demand.
Most preferred embodiment:
Yellow phosphorus furnace slag and fused(calcium magnesium)phosphate work in-process mixed, under 700 ℃ temperature, carry out drying with dryer, as (H by 1: 1.1
2O) content is less than 1% the time, send into feeding machine with bucket elevator, it is levigate to enter ball mill (overflow mill or air swept mill) again, when by 80 eye mesh screens be 80% the time, promptly obtain qualified product, contain phosphorus, silicon, calcium, the multiple element of magnesium in the product, wherein the content of soluble silica is 30%, and effectively the content of Vanadium Pentoxide in FLAKES is 12%.
Claims (3)
1, a kind of silicophosphate fertilizer is characterized in that containing effective Vanadium Pentoxide in FLAKES (P
2O
5) and soluble silica (SiO
2), wherein effectively the content of Vanadium Pentoxide in FLAKES is not less than 2%, and soluble silica is not less than 14%.
2, a kind of manufacture method of silicophosphate fertilizer is characterized in that with yellow phosphorus furnace slag and fused(calcium magnesium)phosphate work in-process be raw material, and yellow phosphorus furnace slag and fused(calcium magnesium)phosphate are by 1: the mixed of 0.05-20 promptly obtains silicophosphate fertilizer after drying is levigate.
3, according to the manufacture method of claim 2, it is characterized in that drying temperature is 600-800 ℃ (or drying under the daylight), when the water content of batching less than 1% the time, it is levigate, and product fineness is to be 80% by 80 eye mesh screens.
