Description
Technical field
The present invention relates to technical field of fertilizer production, and in particular to a kind of organic using stalk as the rich iodine charcoal of raw material production
The method of fertilizer.
Background technology
Iodine is one of essential trace element of human body, and the total amount of the iodine in health adult's body is 30mg (20 ~ 50mg), wherein
70% ~ 80% has Thyreoidine.Iodine, which has, promotes biological oxidation, the synthesis of regulatory protein matter and decomposition, promotes sugar and fat metabolism,
Water-electrolyte metabolism is adjusted, promotes absorbing for vitamin, strengthens the vigor, enhancing development and other effects of enzyme, human body is mended at present
Iodine mode is more based on edible iodized salt and rich iodine food, and rich iodine food is mostly marine product such as shrimp, jellyfish, sea-tangle etc., species compared with
It is few.
The content of the invention
It is an object of the invention to provide a kind of method that rich iodine charcoal organic fertilizer is produced using stalk as raw material.
The technical solution adopted by the present invention is a kind of method that rich iodine charcoal organic fertilizer is produced using stalk as raw material,
（1）Guangxi white clay, clay are pressed into 3-4:1 weight is used as embryo material than mixing, and idiosome is made, then toasted, obtains terrine；
（2）Stalk is crushed to 40-50 mesh, loaded in terrine, is completely filled up being defined by compacting, terrine opening is sealed, is sent into
Calcined in calcining compartment, calcining heat is 550-580 DEG C, and calcination time is 18-22 minutes, after terrine is down to normal temperature, by stalk
Export；
（3）One layer of sea-tangle leaching liquor unreasonable like a shrew on to stalk, make stalk humidity close lid 2-3 days after 96-99%, accumulation；
When sea-tangle leaching liquor makes, it is 25-28% that Fresh Laminaria Japonica is handled to water content under 120-125 DEG C, 0.1-0.15MPa,
80-85 mesh is crushed to, 1 is pressed with water:4-5 volume ratio mixing, with 6000-6200r/min 10-12 points of speed stir process
Clock, standing go to precipitate, and retain supernatant liquid, and the 1/5-1/4 for being concentrated into original volume obtains sea-tangle leaching liquor；
（4）The obtained stalks of accumulation Mi Gai are sent into air flow dryer and are dried to water content in 16-18%, hot-air seasoning temperature
For 45-50 DEG C, obtain drying stalk；
（5）Drying stalk is again loaded into terrine, is completely filled up being defined by compacting, terrine opening is sealed, is sent into calcining compartment
Interior Cyclic Calcination, each calcining heat are 85-88 DEG C, and calcination time is 13-15 minutes, after calcining terminates every time, 3-4 points of interval
Clock, then next calcining is carried out, calcining number is 5-6 times, and last time calcining terminates, and after terrine is down to normal temperature, stalk is led
Go out, obtain rich iodine charcoal organic fertilizer.
Preferably, Guangxi white clay, clay are pressed 3.2:1 weight is used as embryo material than mixing, and idiosome is made, then toasted,
Obtain terrine.
Preferably, when sea-tangle leaching liquor makes, it is 25% that Fresh Laminaria Japonica is handled to water content under 122 DEG C, 0.15MPa,
85 mesh are crushed to, 1 is pressed with water:4 volume ratio mixing, with 6200r/min speed stir process 10 minutes, standing goes to precipitate,
Retain supernatant liquid, be concentrated into the 1/4 of original volume and obtain sea-tangle leaching liquor.
Preferably, Cyclic Calcination, each calcining heat are 88 DEG C, and calcination time is 13 minutes, after calcining terminates every time,
Every 3 minutes, then carry out next calcining.
Beneficial effect of the present invention is that the rich iodine charcoal organic fertilizer of the present invention has life using waste straw as former material is made
Production cost is low, and technique is simple, the advantages such as equipment requirement is low, contains abundant organic iodine in the charcoal organic fertilizer for handling to obtain,
Rich iodine crop can be quickly obtained directly by crop utilization, while have to subterranean pest-insect and necessarily kill left and right, applied in Tanaka, make
With 15-18 days, can fully be killed worm's ovum is remained in field, eradicative rate reaches 92%；
3-4 is pressed by Guangxi white clay, clay:1 weight is than the terrine that mixing makes to obtain as embryo material, and heat transfer performance is good, energy
It is enough to ensure that charing is abundant, uniformly, improve charcoal yield, while can be by straw charring when produced flue gas in sulfur dioxide it is big
Partial adsorbates, reduce contaminative of the charing to environment；
When charcoal organic fertilizer of the present invention specifically makes, rich iodine stalk is obtained using absorption method, stalk fills through being broken to 40-50 mesh
Enter in terrine, be sent into calcining in calcining compartment and calcined at being 550-580 DEG C in calcining heat, calcination process can improve the ratio of stalk
Surface area, the stalk specific surface area for handling to obtain have extremely strong adsorptivity, resulting sea-tangle are soaked up to 1300 ㎡/more than g
Extract is unreasonable like a shrew thereon, can obtain the stalk of organic iodine rich content within a short period of time；
During specific acquisition sea-tangle leaching liquor, it is 25- that Fresh Laminaria Japonica is handled to water content under 120-125 DEG C, 0.1-0.15MPa
28%, contribute to Kelp fiber to crack, sea-tangle gum dispersion, beneficial to the dissolution of I in sea-tangle cell, can finally be had
The abundant sea-tangle leaching liquor of machine content of iodine.
