Abstract
Production of compound fertilizer with silicon, potassium, calcium and magnesium is carried out by adding into potash feldspar, bitter spar, sea salt and conversion agent proportionally, crushing to 100 mesh, putting into blast furnace, calcining, keeping temperature at 780-900DEG C for 1-3hrs, and cooling to obtain the final product. It costs cheap and is simple. It can be used for industrial production.
Description
Technical Field
The invention relates to a preparation method of a silicon-potassium-calcium-magnesium compound fertilizer.
Background
Potash feldspar is a poorly soluble potassium-containing mineral, widely distributed in magma rock, metamorphic rock and sedimentary rock,and belongs to silicate. Potassium in the potash feldspar and other potassium-containing silicates can not be absorbed by plants basically, and the potassium can be used as a potassium fertilizer only after being made soluble or citrate-soluble by chemical processing. The process for preparing the potash fertilizer is difficult, the production cost is high, and large-scale industrial production is not carried out at present. The research of preparing potash fertilizer with potash feldspar began from the beginning of the 20 th century at home and abroad, dozens of process researches were carried out successively, the low-temperature decomposition method is a promising method for preparing potash fertilizer with potash feldspar, in order to improve the conversion rate, some transforming agents or cosolvent are often added into the raw materials, but the cost is higher, and in order to achieve the purpose of low cost, cheap cosolvent or transforming agent must be found.
Disclosure of Invention
The invention aims to solve the technical problem of providing a preparation method of a silicon-potassium-calcium-magnesium compound fertilizer by utilizing abundant insoluble potassium resources in China.
The specific technical scheme is as follows: the preparation method of the silicon-potassium-calcium-magnesium compound fertilizer comprises the following steps: the weight portion ratio is: 1 part of potassium feldspar, 0.5-1.4 parts of dolomite and 0.5-1.8 parts of sea salt;
the raw materials are also provided with 0.15 to 1.5 parts of transforming agent;
pulverizing the above materials and transforming agent into powder, and mixing;
after roasting.
The transforming agent is any one substance or two or three mixtures of sodium hydroxide, sodium bicarbonate and boromagnesite.
The above raw materials and transforming agent are pulverized into powder with fineness of 100-200 meshes.
The roasting is carried out in a blast furnace, the roasting is kept for 1 to 3 hours at the high temperature of 780 to 900 ℃, and the silicon-potassium-calcium-magnesium compound fertilizer can be obtained after the roasting is taken out and cooled.
The potash feldspar is matched with dolomite and sodium chloride, and the silicon-potassium-calcium-magnesium fertilizer is prepared by roasting, and is a method combining a thermochemical conversion method and a thermal sintering method. The main components of the finished product of the silicon-potassium-calcium-magnesium compound fertilizer obtained after roasting are albite, potassium metaaluminate, potassium chloride, sodium silicate, dicalcium silicate, magnesium oxide and the like, and the potassium salt exists in the forms of potassium metaaluminate and potassium chloride. The overall reaction in this formulation can be expressed as:
the silicon-potassium-calcium-magnesium compound fertilizer has good effects of promoting the growth of crops, improving the product and quality, enhancing the disease resistance and lodging resistance of plants, improving the effect of nitrogen and phosphate fertilizers, and simultaneously neutralizing the acidity of soil. The production of the silicon-potassium-calcium-magnesium compound fertilizer has the advantages of rich resources, simple process, easy operation, low cost and the like.
Detailed Description
Example 1:
mixing 1 ton of potassium feldspar, 0.8 ton of dolomite, 1.5 ton of sea salt and 0.4 ton of conversion agent containing sodium hydroxide, sodium bicarbonate and ascharite, pulverizing the above-mentioned potassium feldspar, dolomite, sea salt and conversion agent into 100 meshes by means of pulverizing machine and ball mill, uniformly mixing them to ensure the dissolution rate of water-soluble potassium, placing them into blast furnace, sintering at high temperature of 850 deg.C for 3 hr, taking out and cooling so as to obtain the invented product silicon-potassium-calcium-magnesium composite fertilizer.
Example 2:
the potassium feldspar, the dolomite, the sea salt and the transforming agent are crushed into 20 meshes by a crusher according to the proportion of 1 ton of potassium feldspar, 1 ton of dolomite, 1.3 ton of sea salt and 0.3 ton of transforming agent containing sodium hydroxide, sodium bicarbonate and boron magnesium, the potassium feldspar, the dolomite, the sea salt and the transforming agent are uniformly mixed and crushed into 200 meshes in a ball mill, the mixture is put into a blast furnace and sintered for 1.5 hours at the high temperature of 800 ℃, and the mixture is taken out and cooled to obtain the silicon-potassium-calcium-magnesium compound fertilizer.
Tests show that the silicon-potassium-calcium-magnesium compound fertilizer prepared by the method contains 4-5% of potassium oxide, 20-30% of soluble silicate, 8% of calcium oxide and 5-6% of magnesium oxide, and is an alkaline fertilizer.
