Abstract
The granular composite fertilizer consists of urea 45-50 weight portions, potassium chloride or potassium sulfate 20-25 weight portions, ammonium phosphate 20-30 weight portions and stuffing 1-5 weight portions. It is prepared by using high temperature molten urea as carrier to fuse the materials homogeneously and through tower top showering to cool and pelletize. The tower has height of 60-120 m and diameter of 8-20 m. During preparation, water is introduced continuously for adhering to pelletize without caking. The melt composite fertilizer preparing process has the advantages of no material returning, greatly raised production capacity, low power consumption, high apparatus utilization, less environmental pollution, etc.
Description
Technical field
The present invention relates to a kind of melt slime granulating composite fertilizer and manufacture method thereof.Belong to the agricultural fertilizer field.
Background technology
At present, be used for all kinds of composite fertilizers (mixing fertile) of farm crop, several problems of existence are that fertilizer is deposited easy caking, and particle is not slick and sly, and is inhomogeneous, and nutrient proportioning instability, is unfavorable for the balanced fertilising in farmland.
Simultaneously since the composite fertilizer that traditional prilling process is produced (mixing fertile) since granulation process belong to simple physics sticking and, structure is more open, the fertilizer dissolving discharges very fast, fertilizer efficiency is decomposed and is run off soon, utilization rate of fertilizer is lower.Dry screening process after traditional granulation, energy consumption consumption is big.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of melt slime granulating composite fertilizer and manufacture method thereof.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of manufacture method of melt slime granulating composite fertilizer, melt slime granulating composite fertilizer is made up of the component of following weight proportion;
Urea: 45～50 parts; Repone K or vitriolate of tartar: 20～25 parts; Ammonium phosphate: 20～30 parts; Weighting agent: 1～5 part;
Manufacturing processed adopts high-temperature fusion urea to do carrier, and raw material is merged evenly, through cat head spray cooling granulating, following steps is arranged again;
Step 1: a kind of raw material urea through 130 ℃～145 ℃ of high-temperature fusion, is entered in the dashpot, through the transferpump pressurization, deliver to after metering in the cat head tempering tank again;
Step 2: after other raw material Repone K (vitriolate of tartar), ammonium phosphate and weighting agent (talcum powder) measured respectively, send into thorough mixing in the agitator according to above-mentioned proportioning;
Step 3: the mixing raw material in the step 2 behind crushing and screening, is risen to the cat head feed bin by chapelet;
Step 4: with the batch mixing in the feed bin in the step 3, behind screw feeder, send in the batch mixing well heater, be heated to 60～95 ℃;
Step 5: the batch mixing after the heating in the above-mentioned steps 4 is sent into described in the above-mentioned steps 1 in the mixing tank, make material of sticky shape through mixing fast, temperature is controlled at 115 ℃～120 ℃, automatic overflow is to prilling spry, under the effect of shower nozzle rotary centrifugal force, mixture is evenly sprayed into globular small droplets;
Step 6: adopt cat head spray natural cooling technology, the small droplets that falls from the shower nozzle spray in the above-mentioned steps 5 freely falls in the tower of 8～20 meters of diameters, through with tower in natural upstream heat exchange postcooling to 40～60 ℃, the once shaped granulating promptly becomes composite fertilizer's small-particle.
Tower height is at 60～120 meters, and tower diameter is at 8～20 meters.In system, do not introduce the bonding granulation of moisture in the preparation process, can prevent to lump because of Moisture high UCL.
Advantage of the present invention is: the compound manure of the present invention's preparation is on the microcosmic molecular level, with raw materials such as urea, Repone K, phosphorus ammonium, vitriolate of tartar, be fused into an organic nutrient integral body,, form isostatic and stablize the nutrient unit by the interaction between the various nutrients.Like this, can continuously discharge nutrient, be made for thing and absorb, thereby reduce the decomposition loss of fertilizer in the farmland, improve chemical fertilizer utilization ratio according to absorbing state in each vegetative period of farm crop to Different Nutrients.
The melting method composite fertilizer of the present invention's preparation, the characteristics of a maximum adopt high-temperature melting method exactly in preparation process, raw material is merged together, its process has been avoided introducing moisture and has been dissolved in system, thereby prevented, thereby the trouble of having avoided storage and having used because of Moisture high UCL makes fertilizer agglomeration.Dry screening process after having saved traditional granulation simultaneously, thereby save energy consumption.
The melting method composite fertilizer of the present invention's preparation, what adopt in preparation process is high tower spray naturally cooling, a granulating forming technique, there is not returning charge in this technology, and throughput is greatly improved, and has avoided defect low because of the traditional method granulating rate, that returning charge is many, save the energy, improve plant factor.Because of almost there not being the returning charge dust pollution, Working environment is more cleaned simultaneously, avoided three waste discharge.
