Abstract

The invention discloses a production method of a water-soluble compound fertilizer. The steps include: 1. material compounding: pouring urea, monoammonium phosphate, potassium nitrate and potassium dihydrogen phosphate into respective bucket elevator and then to a metering scale to conduct feeding respectively; 2. raw material treatment: subjecting the urea to steam heating melting; 3. mixing: letting melt liquid overflow into a mixing reaction groove, mixing the melt liquid with the monoammonium phosphate, potassium nitrate and potassium dihydrogen phosphate fed into the mixing reaction groove fully to carry out reaction; 4. spray granulation: letting the mixed slurry overflow into a granulator to conduct spray granulation; 5. cooling: sending the granulated material into a cooling roller to conduct cooling rapidly; and 6. wrapping of the finished product: wrapping finished product particles with a wrapping agent, then conducting quantitative packaging, and putting the product into a finished product warehouse. The finished product produced by the method provided by the invention not only has the advantages and features of ordinary compound fertilizers, but also has the advantages and features of water soluble fertilizers. The prepared finished product is round particles with shrinkage pores and completely water soluble, is in line with the water soluble fertilizer standards, can be applied to common fertilization, and also can be dissolved in water to be sprayed as a water-soluble fertilizer.

Description

A kind of production method of water-soluble composite fertilizer
Technical field
The present invention relates to a kind of production method of composite fertilizer, particularly relate to a kind of production method of water-soluble composite fertilizer.
Background technology
The general name of the fertilizer that composite fertilizer is mixed with compound fertilizer mutually by several straight fertilizer or straight fertilizer.
Water soluble fertilizer is a kind of polyelement composite fertilizer that can be completely water-soluble, it can promptly be dissolved in the water, more easily absorbed by crops, and its absorption rate is relatively high, more crucially it can be applied to the industrialized agricultures such as spray drop filling, realize water-fertilizer integral, reach the usefulness that water-saving economizes fertile saving of labor.
The advantage how gathering water soluble fertilizer, in composite fertilizer, makes it in use compared with ordinary compound fertilizer, time and labour saving, can be dissolved in the water rapidly, noresidue, more easily absorbed by crops, absorption rate is relatively high, not only possesses the advantage of ordinary compound fertilizer, can also be applied to spray drip irrigationdeng facility, realize water-fertilizer integral, reach the usefulness that water-saving economizes fertile saving of labor.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of production method of water-soluble composite fertilizer.
For achieving the above object, the technical solution adopted in the present invention is: a kind of production method of water-soluble composite fertilizer, and step is as follows:
One, prepare burden: pour urea, monoammonium phosphate, saltpetre, potassium primary phosphate into respective bucket elevator to weigher, feed intake respectively by the mass ratio of urea 40 ~ 45, potassium primary phosphate 30 ~ 35, monoammonium phosphate 5 ~ 10, saltpetre 17 ~ 22;
Two, Feedstock treating: the urea fed intake is entered melting device, steam heating melting, melting device temperature arranges 130 DEG C, melting device vapor pressure 0.9 ~ 1.2MPa;
Three, mix: fused solution overflow enters hybrid reaction groove, and be dosed to the monoammonium phosphate of hybrid reaction groove, saltpetre, potassium primary phosphate mixing fully reaction, tempering tank temperature arranges 130 ~ 135 DEG C, insulation steam 0.2 ~ 0.6MPa;
Four, sprinkling pelleting: the slip overflow after mixing in step 3, enters tablets press sprinkling pelleting, vapor pressure 0.9 ~ 1.2MPa;
Five, cool: by after step 4 granulation particle send into cooling drum cool rapidly, roto-sifter sifts out returning charge particle, and finished particle removes pack roller, cooling temperature 30 ~ 35 DEG C, cooling time 20 ~ 30min;
Six, coating finished product: finished particle after coating agent parcel, is sent into finished product sizing screen, enter stockyard after quantitative package in pack roller.
Further, the water of condensation that described steam produces enters back pool.
Advantageous Effects of the present invention is: the finished product that this production method is produced, not only possesses ordinary compound fertilizer advantageous properties, also possesses water soluble fertilizer advantageous properties, prepared finished product is circular strip shrinkage hole particle, entirely water-soluble, meet water-soluble fertilizer standard, can commonly apply fertilizer, also spray as Water soluble fertilizer in water soluble and use.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
embodiment 1
A production method for water-soluble composite fertilizer, step is as follows:
One, prepare burden: pour urea, monoammonium phosphate, saltpetre, potassium primary phosphate into respective bucket elevator to weigher, feed intake respectively by the mass ratio of urea 40 ~ 45, potassium primary phosphate 30 ~ 35, monoammonium phosphate 5 ~ 10, saltpetre 17 ~ 22;
Two, Feedstock treating: the urea fed intake is entered melting device, steam heating melting, melting device temperature arranges 130 DEG C, melting device vapor pressure 0.9 ~ 1.2MPa;
Three, mix: fused solution overflow enters hybrid reaction groove, and be dosed to the monoammonium phosphate of hybrid reaction groove, saltpetre, potassium primary phosphate mixing fully reaction, tempering tank temperature arranges 130 ~ 135 DEG C, insulation steam 0.2 ~ 0.6MPa;
Four, sprinkling pelleting: the slip overflow after mixing in step 3, enters tablets press sprinkling pelleting, vapor pressure 0.9 ~ 1.2MPa;
Five, cool: by after step 4 granulation particle send into cooling drum cool rapidly, roto-sifter sifts out returning charge particle, and finished particle removes pack roller, cooling temperature 30 ~ 35 DEG C, cooling time 20 ~ 30min;
Six, coating finished product: finished particle after coating agent parcel, is sent into finished product sizing screen, enter stockyard after quantitative package in pack roller.
The water of condensation that described steam produces enters back pool.
embodiment 2
A kind of production method of water-soluble composite fertilizer, difference from Example 1 is: step one, batching: pour urea, monoammonium phosphate, saltpetre, potassium primary phosphate into respective bucket elevator to weigher, feed intake respectively by the mass ratio of urea 42, potassium primary phosphate 32, monoammonium phosphate 7, saltpetre 19.
The mass ratio used in embodiment 2 is optimum proportioning.
The powder come from material process enters powder material warehouse through bucket elevator; then enter one-level hybrid reaction groove through weigher, bucket elevator to carry out rapid reaction in proportion with the solution that melting operation is come and mix; slip overflow after mixing enters tablets press and carries out granulation; material freely falls into belt, through Belt Conveying to finished product process.According to on-the-spot feedback information, use automatic control program regulate process to control, the work coordinated between concerned process steps coordinates, and ensures the stable of material proportion and operations index, ensures to produce continous-stable.At the bottom of prilling tower Belt Conveying come material through going out tower belt, finished product bucket elevator reaches cooling drum, returning charge particle is sifted out to roto-sifter, finished particle removes pack roller, after coating agent parcel, sending into finished product bucket and mention that feed belt is to sizing screen to packaging process, is enter stockyard after product through quantitative package.
