Abstract
The invention relates to a nanoparticle compound fertilizer. The nanoparticle compound fertilizer comprises the following components in parts by weight: 50-80 parts of coal ash, 10-20 parts of chemical fertilizer, 5-8 parts of sodium carbonate and 1-2 parts of a cement. The nanoparticle compound fertilizer is prepared by the following steps: weighing coal ash and sodium carbonate, and then putting the coal ash and sodium carbonate into a grinding container to be ground for 30 minutes; adding the ground coal ash and sodium carbonate into a stirring container to be stirred uniformly; adding water and stirring the coal ash and sodium carbonate, and then adding stirred coal ash and sodium carbonate into a reaction kettle to be aged and crystallized; filtering the aged and crystallized coal ash and sodium carbonate, and washing to obtain a coal ash crystal; drying the coal ash crystal to obtain coal ash powder; pelletizing the coal ash powder, the chemical fertilizer and the cement, or adding water and uniformly mixing the coal ash powder and the cement and then pelletizing; using a spray gun to continuously spray mist on pelletized coal ash particles in a stirred movement for being packed, and then drying to obtain the nanoparticle compound fertilizer. The process of the nanoparticle compound fertilizer is simple, the producing cycle is short, and waste liquor can be heated and concentrated for recycling and circulating reuse, so that the manufacturing cost is further reduced.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of nanoparticle compound manure and preparation method thereof.
Background technology
According to ASSOCIATE STATISTICS, chemical fertilizer drops into and to account for peasant and carry out plant husbandry and produce total 50% left and right of dropping into, 50% effect that comes from chemical fertilizer in developing country's increases in grain production.But China's this season utilization rate of nitrogen fertilizer is only 20%～35% at present, and the utilization ratio of phosphate fertilizer is 10%～20%, and the utilization ratio of potash fertilizer is 30%～60%, far below World Developed Countries, utilizes level.The low huge waste that not only causes resource of utilization rate of fertilizer, returns the environment that the mankind depend on for existence and has caused severe contamination.Therefore sustained-controll-release fertiliser has become focus new in fertilizer circle research field.Slow-release or control-release fertilizer comprises slow-release fertilizer and Controlled Release Fertilizer, and slow-release fertilizer is the important way that improves fertilizer utilization efficiency.
CN102249797A as open in Chinese patent, relate to a kind of slow-release material and preparation method and purposes that modified zeolite is carrier of take, by mass percentage, by modified zeolite 94%-98%, chitosan 1%-3%, acrylamide 1%-3%, formed, modified zeolite preparation method is through 200 ℃ of-400 ℃ of pyroprocessing 1.5h-3h by natural zeolite, after crushing and screening, with the salt acid soak 0.5-2h of 0.5-2mol/l, carry out framework dealumination simultaneously; By being ground to the trickle powder of 200 order-300 object with powder equipment after the Zeolite dehydration after acid treatment, make modified zeolite; 94%-98% modified zeolite interpolation 1%-3% chitosan, 1%-3% acrylamide are mixed and make slow-release material.Slow-release material, according to accounting for fertilizer quality than making an addition in fertilizer for the ratio of 5%-20%, is produced to environment-friendly type slow release fertilizer.
But above-mentioned employing zeolite is high as its raw materials cost of slow-release fertilizer carrier, and pyroprocessing is high to equipment requirements, carrier cannot be degraded harmful to soil simultaneously.
Summary of the invention
High in order to solve existing its raw materials cost of slow-release fertilizer carrier, pyroprocessing is high to equipment requirements, and simultaneously the carrier shortcoming harmful to soil of cannot degrading, the invention provides a kind of nanoparticle compound manure and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of nanoparticle compound manure, its component, in weight fraction, comprises 50-80 part flyash, 10-20 part chemical fertilizer, 5-8 part sodium carbonate, 1-2 part cakingagent.
A preparation method for nanoparticle compound manure, preparation process is as follows:
(1) flyash and sodium carbonate add in grinding container and grind 30 minutes after weighing;
(2) flyash after grinding and sodium carbonate being put into stirred vessel stirs;
(3) flyash and the sodium carbonate that add after water stirs are added to ageing crystallization in reactor;
(4) flyash after aging crystallization and sodium carbonate are filtered and washed obtain flyash crystal;
(5) after flyash crystal is dried flyash powder;
(6) by flyash powder and chemical fertilizer and cakingagent granulation or flyash powder and cakingagent are added to water mix rear granulation, and then with spray gun to having made in advance the fly ash grain in stirring movement of grain constantly spray parcel then oven dry.
The invention has the beneficial effects as follows: technique is simple, with short production cycle, and waste liquid can heat concentration and recovery/circulation and re-use, and further reduces production costs.
Embodiment
To describe the present invention in detail with specific embodiment below, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
Embodiment 1, will after 50-80 part flyash and the weighing of 5-8 part sodium carbonate, add in grinding container and grind 30 minutes; Flyash after grinding and sodium carbonate are put into stirred vessel to stir; The flyash and the sodium carbonate that add after water stirs are added to ageing crystallization in reactor; Flyash after aging crystallization and sodium carbonate are filtered and washed and obtain flyash crystal; After being dried, flyash crystal obtains flyash powder; By flyash powder and 10-20 part chemical fertilizer and the cakingagent granulation of 1-2 part or flyash powder and 1-2 part cakingagent are added to water mix rear granulation; and then with spray gun to having made in advance the parcel of constantly spraying of fly ash grain in stirring movement of grain, then oven dry.
The present invention not only technique is simple, with short production cycle, and waste liquid can heat concentration and recovery/circulation and re-use, and further reduces production costs.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
