Abstract
The present invention relates to a kind of attapulgite modified compound fertilizers, it is characterised in that is mixed with by weight percentage by following ingredients；Attapulgite powder 10-20%, urea 10-20%, ammonium sulfate 15-20%, potassium sulfate 20-30%, monoammonium phosphate 25-35%, ammonium hydrogen carbonate 3-5%, sulfuric acid urea solution 5-8%.The reaction heat of sulfuric acid and water, urea and sulfuric acid is rationally utilized, steam consumption is also greatly reduced because sulfuric acid urea solution has high viscosity in pelletizer, and energy-saving effect is obvious.Continuous production can be achieved, improve production efficiency.
Description
Technical field
The present invention relates to technical field of fertilizer production, especially a kind of attapulgite modified compound fertilizer.
Background technique
Compound fertilizer's appearance is generally graininess, and primary raw material has ammonium sulfate, ammonium nitrate, urea, potassium sulfate, potassium chloride etc..
Have many advantages, such as that high, the secondary composition of nutrient content is few and physical behavior is good, for balance fertilizing, improves utilization rate of fertilizer, promote to make
Object stable high yield has a very important role.Concave convex rod mine modified compound fertilizer has nanoporous road column structure, distinctive
The loss of the adsorbable nitrogen of absorption property；It is also beneficial to save the nutrients such as phosphorus potassium, improves the utilization rate of fertilizer, reduce effectively
The loss of nutrient.The prior art produces concave convex rod compound fertilizer, attapulgite powder is usually first acidified, by attapulgite powder and sulphur
Acid-mixed is stacked after closing.It is big that this mode stacks place, also needs ceaselessly to stir, and mixing is uneven, cannot achieve serialization
Production.
Summary of the invention
It is an object of the invention to avoid the deficiencies in the prior art, a kind of attapulgite modified compound fertilizer is provided.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of attapulgite modified compound fertilizer, feature exist
In being mixed with by weight percentage by following ingredients；
Attapulgite powder 10%-20%, urea 10-20%, ammonium sulfate 15-20%, potassium sulfate 20-30%, monoammonium phosphate 25-
35%, ammonium hydrogen carbonate 3-5%, sulfuric acid urea solution 5-8%；
Preparation method includes the following steps:
A. it prepares attapulgite fine powder: by attapulgite clay mineral through picking → drying → broken → ore grinding → classification, being made
- 150 targeted fine powder of 100 mesh, water content≤15%, color are canescence or red；
B. sulfuric acid urea solution is prepared: by being mixed evenly for 93% sulfuric acid, urea, water 1:2:0.1 in mass ratio, temperature control
40-60 DEG C processed；
C. be granulated: by attapulgite powder, urea, ammonium sulfate, potassium sulfate, monoammonium phosphate, ammonium hydrogen carbonate is proportionally added into granulation
Machine, then ureasulfuric acid solution atomization is sprayed onto pelletizer material bed surface, flow is controlled with flowmeter；
D. packaging will be carried out after the particle drying made, cooling, screening, coating, metering forms complex fertilizer product.
The beneficial effects of the present invention are:
1, the reaction heat of sulfuric acid and water, urea and sulfuric acid is rationally utilized, dissolved urea forms sulfuric acid urea solution and do not have to steam, complete
Reaction heat is relied on entirely, and steam consumption is also greatly reduced because sulfuric acid urea solution has high viscosity in pelletizer, and energy-saving effect is obvious.
2, due to the porous crystal structure of concave convex rod, good improvement soil effect is made it have；Simultaneously again using concave-convex
The colloidality and adsorptivity of stick add sulfuric acid urea solution caking property, and granulation is strong, and pelletizer outlet granulating rate reaches 95%,
Particle surface roundness degree increases, and compression strength improves, and grain color bleaches, and commodity is good；
3, due to ureasulfuric acid inhibition, make efficiency slow release, extend fertilizer efficiency.
4, attapulgite powder is acidified using dynamic, the method for serialization, is acidified, is uniformly mixed, feeds intake stabilization, can
It realizes continuous production, improves production efficiency.
Specific embodiment
The principles and features of the present invention are described below, and the given examples are served only to explain the present invention, is not intended to limit
Determine the scope of the present invention.
Embodiment 1, a kind of attapulgite modified compound fertilizer, it is characterised in that mixed by weight percentage by following ingredients
Preparation；
Attapulgite powder 20%, urea 10%, ammonium sulfate 15%, potassium sulfate 22%, monoammonium phosphate 25%, ammonium hydrogen carbonate 3%, sulphur
Sour urea solution 5%
Preparation method includes the following steps:
A. it prepares attapulgite fine powder: by attapulgite clay mineral through picking → drying → broken → ore grinding → classification, being made
- 150 targeted fine powder of 100 mesh, water content≤15%, color are canescence or red；
B. sulfuric acid urea solution is prepared: by being mixed evenly for 93% sulfuric acid, urea, water 1:2:0.1 in mass ratio, temperature control
40-60 DEG C processed；
C. be granulated: by attapulgite powder, urea, ammonium sulfate, potassium sulfate, monoammonium phosphate, ammonium hydrogen carbonate is proportionally added into granulation
Machine, then ureasulfuric acid solution atomization is sprayed onto pelletizer material bed surface, flow is controlled with flowmeter；
D. packaging will be carried out after the particle drying made, cooling, screening, coating, metering forms complex fertilizer product.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Any modification, equivalent replacement, improvement and so within principle, should all be included in the protection scope of the present invention.
