Abstract
The invention relates to a production method of a large particle humic acid-potassium chloride fertilizer, and belongs to the technical field of manufacturing of efficient fertilizers. The method comprises the following steps of: mixing a sodium hydroxide solution with humic acid raw ore for reaction to activate the humic acid raw ore; dispersing and spraying activated slurry to the mixture of potassium chloride and humic acid raw ore for granulating by a rotary drum; and then, drying, cooling, screening and packaging. The production method provided by the invention solves the problem of high corrosivity to equipment, low production capacity, weak strength, severe operating environment and difficulty in realizing large-scale and industrialized production caused by extrusion-granulating of the potassium chloride fertilizer. Meanwhile, the potassium chloride fertilizer and humic acid are organically fused, so that soil is improved and the fertilizer effect is extremely enhanced.
Description
Technical field
A kind of big granule humic acid of the present invention Repone K fertilizer production method belongs to concentrated fertilizer manufacturing technology field.
Background technology
Repone K is present a kind of potash fertilizer of usage quantity maximum in the world, is all accounting for more than 90% in the potash fertilizer consumptions.China consumed 1,080 ten thousand tons in potash fertilizer, 5,800,000 tons in wherein homemade potash fertilizer, 5,000,000 tons in import potash fertilizer in 2011.70% of potash fertilizer is to execute the farmland with pulverulence.Repone K is white or blush xln, and is soluble in water, and water absorbability is arranged, and long storage can be lumpd, and the content of impurity is high more, and its water absorbability is strong more, more easily caking.
Inconvenience is used, transported to powdery Repone K, and take place easily when directly using to burn seedling, and nutrient loss is serious, can not carry out mechanical fertilization, can not do the raw material of Bulk Blending Fertilizer, and macrobead Repone K just can change these deficiencies.Extrusion process is generally adopted in powdery Repone K granulation at present, and the granular potash fertilizer of gained is irregular, and low, the weak strength of throughput, equipment corrosion are serious simultaneously, and are difficult to realize extensive, industrialization production.
When using Repone K fertilizer, cause soil acidification easily, crop is easy to suck too much chlorion, influences the quality product of some cash crop.
Summary of the invention
The present invention is exactly at above deficiency, research and develop a kind of big granule humic acid Repone K fertilizer production method, solved that the equipment corrosion that Repone K fertilizer extruder grain brings is big, throughput is low, weak strength, severe operational environment, and be difficult to realize problem extensive, that industrialization is produced, simultaneously Repone K fertilizer and humic acids are organically blended, the structure of improving the soil greatly strengthens fertilizer efficiency.
For achieving the above object, the technical solution used in the present invention is: big granule humic acid Repone K fertilizer production method, it is characterized in that: sodium hydroxide solution and humic acids raw ore are pressed 1:(0.25-1.5) after the mixed 10-100 ℃ of reaction 5-15 minute down, carry out the activation of humic acids raw ore, it is 20-100 ℃ that slip after the activation is disperseed to be sprayed onto temperature, ratio is on the mixture of the Repone K of 2-10:0-1 and humic acids raw ore, carry out drum granulating, it is 200-300 ℃ in inlet temperature then, temperature out 50-100 ℃ of oven dry down cooled off again, screening, packing.
Described concentration of sodium hydroxide solution is 0.1-20%.
The invention has the beneficial effects as follows:
1, the present invention makes binding agent with Sodium salts humic acids, and the rotary drum granulating method is produced granulated fertilizer, has realized avoiding the wasting of resources with fertilizer bag fertilizer.Solved that the equipment corrosion that Repone K fertilizer extruder grain brings is big, throughput is low, weak strength, severe operational environment, and be difficult to realize problem extensive, that industrialization is produced.
2, the present invention has added the activatory humic acids in Repone K fertilizer, gives full play to the good effect of humic acids to aspects such as the output of soil, fertilizer nutrient, environment, crop, qualities, has reduced the undesirable action of chlorion in the fertilizer.
3, the present invention is applied to sodium hydroxide activation humic acids raw ore technology in the fertiliser production, like this can be than faster, more thorough with bicarbonate of ammonia, ammoniacal liquor activation humic acids raw ore, and easier industrialization.When having solved simultaneously, to the pollution of environment, to operator's injury, the disadvantage of the easy moisture absorption with bicarbonate of ammonia, ammoniacal liquor activation humic acids raw ore.
Description of drawings
Fig. 1 is the process flow sheet of big granule humic acid Repone K fertilizer production method of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
