Abstract
The invention relates to a silicon fertilizer and a production method thereof, belonging to the field of plant fertilizers and production methods thereof. The silicon fertilizer contains the following materials in parts by weight: 39.4 parts of bentonite, 30.3 parts of pulverized coal ash, 30 parts of sodium hydroxide liquid caustic soda containing 30 percent of alkali, 0.25 part of catalyst magnesium oxide and 0.05 part of aluminium oxide. The production method of the silicon fertilizer comprises the following steps: processing the pulverized coal ash by an all-powerful pulverizer; putting 50 parts of the processed pulverized coal ash, 49.5 parts of sodium hydroxide solutions containing 30 percent of the alkali, 0.416 part of the magnesium oxide and 0.084 part of the aluminium oxide into a double-helix conical mixer to form soluble silicon fertilizer materials; placing the silicon fertilizer materials into a cement material pool; then putting 60.6 parts of the silicon fertilizer materials and 39.4 parts of the bentonite into a double-shaft horizontal type mixer for mixing, and then putting the mixture into a granulating disc; putting the dried silicon fertilizer into a cooler to enter a sieving machine for being sieved; and circularly producing the silicon fertilizer. The silicon fertilizer enhances the air permeability of soil, regulates the pH value of the soil, plays a soil improvement role and is suitable for the fertilization of various crops.
Description
Technical field
The invention belongs to vegetable fertilizer and working method, particularly a kind of siliceous fertilizer and working method.
Background technology
At present, the siliceous fertilizer ubiquity of selling on the market effectively silicon (SiO
2) content is low has only 10～20%, and the raw material that most of siliceous fertilizer uses is blast furnace slag, afterwards plant absorbing is slow in fertilising, does not have the ideal role of siliceous fertilizer.Can not make plant fully absorb nutrient, improve crop yield, to soil improvement, disease-resistant, antibiotic, the poison resistance of plant prevent lodging effect shortcoming.In addition, though a kind of siliceous fertilizer effect in the process that plant absorbing is utilized that is transformed by silica sand and yellow soda ash is better, its production cost is high, and invert point needs about 1400 ℃, need transformation time long, wastes energy.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of production cost low, fast to the plant absorbing utilization, it is obvious to improve the output effect, helps a kind of siliceous fertilizer and the working method of soil.
The technical scheme that technical solution problem of the present invention adopts is: a kind of siliceous fertilizer and working method are characterized in: flyash is handled through Universalpulverizer, made its fineness>=100 orders, moisture content≤1%; By weight, in 0.084 part of input of 50 parts in flyash, 49.5 parts of the caustic lye of sodas of alkalinity 30%, 0.416 part in Natural manganese dioxide, the aluminium sesquioxide Conicaldoublewormmixer after handling, stirred 14～16 minutes; The material that mixes is sent in the hotblast stove, under 800～900 ℃ of temperature, transformed one hour, become solubility siliceous fertilizer material; Siliceous fertilizer material after the pyrolytic conversion is put into the cement material pond lowered the temperature naturally 3 hours, the siliceous fertilizer material after the cooling is sent in the Universalpulverizer after trickle is handled, and is crushed to fineness>=100 orders; 60.6 parts of siliceous fertilizer materials after will pulverizing are again sent into to mix in the biaxial type flat mixer with 39.4 parts of wilkinites and are delivered in the granulation dish after 14～16 minutes, are a granulated into the particle rate>=85% o'clock discharging of 1～4.75mm through water spray; Send in the dryer and dry; The temperature of dryer burner>=400 ℃, stove tail temperature is 50 ℃ ± 5 ℃, the siliceous fertilizer after the oven dry is sent in the cooler and is cooled off; Be cooled to the siliceous fertilizer temperature and after 30 ℃, get into the sifted branch; Particle diameter is packed for the finished product siliceous fertilizer 1～4.75mm's, pulverizes cyclic production again less than 1mm or greater than the siliceous fertilizer of 4.75mm.
The invention has the beneficial effects as follows: the main raw material of the staple siliceous fertilizer material of a kind of siliceous fertilizer and working method is a flyash, and it is with low cost, and is utilization of waste material, helps environmental protection, reduces the floor space of flyash.It is very big that farm crop are improved the output effect, and farm crop are played antibiotic, disease-resistant, antitoxin effect, prevents plant lodging.This siliceous fertilizer strengthens the ventilation property of soil, regulates the potential of hydrogen of soil, plays soil improvement action, is applicable to that using of various farm crop is fertile.
Embodiment
Below in conjunction with embodiment the present invention is described further.
Embodiment, a kind of siliceous fertilizer and working method, the main raw material in its siliceous fertilizer is a flyash, and flyash is sieved, fineness guarantees at>=100 orders; Do not reach 100 purposes through the Universalpulverizer pulverization process, make its moisture≤1%.Get the flyash 500Kg that pulverizes after qualified; The sodium hydroxide liquid caustic soda 49.5Kg of alkalinity 30%; Catalyst oxidation magnesium 0.416Kg, aluminium sesquioxide 0.084Kg send in the double helical form mixing machine, stir 14～16 minutes; Sending into the material that stirs in the indirect sleeve hotblast stove, is to transform under 800～900 ℃ of temperature to become available silicon content in one hour greater than 33% vitreum siliceous fertilizer sodium silicate raw material in furnace temperature.The siliceous fertilizer material of pyrolytic conversion is gone in the cement material pond, and cooling is 3 hours naturally, and the siliceous fertilizer material of cooling is sent into behind trickle in the Universalpulverizer, pulverizes back fineness >=100 orders.Get the siliceous fertilizer material 606Kg that pulverizes after qualified; Wilkinite 394Kg sends in the double-shaft horizontal mixing machine, mixes and sends in the granulation dish after 14～16 minutes, send in the granulation dish siliceous fertilizer through the water spray granulation; Make particle rate >=85% of its granulation to 1～4.75mm o'clock begin discharging; Send in the dryer and dry, the end flue temperature of dryer >=400 ℃, 50 ℃ ± 5 ℃ of stove tail temperature.Siliceous fertilizer after the oven dry is sent in the cooler, to be cooledly takes out screening to＜30 ℃ the time, reach 1～4.75mm particle diameter as finished product packing, send in the mixing machine less than 1mm, greater than the siliceous fertilizer of 4.75mm and to pulverize cyclic production again.Effective silicon (solvable SiO of finished product siliceous fertilizer
2) content>=20% is salable product.
Illustrate the method for use and the effect of siliceous fertilizer below:
