Embodiment 1

[0026] Combine 2.25Kg of unactivated powdery weathered coal A and 0.24975Kg of solid activator B, wherein in solid activator B: the mass of sodium oxide and potassium oxide accounts for 70% of the total solid activator B mass ratio, and contains oxidized The mass of basic oxides such as barium and manganese oxide accounts for 30% of the mass ratio of the total solid activator B. Mix A and B thoroughly. Then, add 0.00025Kg synergist C (composed of one or two kinds of nano-copper, nano-iron metal particles) to the mixture of A and B; finally, put the above-mentioned mixture into the ball mill, and adjust the rotating speed of the ball mill to be 80r , the time is 60min to generate activated humic acid. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which can save half of the energy (the tem...

Embodiment 2

[0028] With the unactivated powdery weathered coal A of 2.76Kg and the activator B of 0.2391Kg, the sodium oxide and potassium oxide quality that wherein activator B contains account for 75% (mass ratio) of total solid activator B, the barium oxide contained Basic oxides such as manganese oxide and iron oxide account for 25% (mass ratio) of the total solid activator B. Mix A and B thoroughly. Then, add 0.0009Kg synergist (composed of one or two kinds of nano-copper and nano-iron metal particles) to the mixture of A and B. At last, the above-mentioned mixture is put into a ball mill, and the rotating speed of the ball mill is adjusted to be 80r, and the time Activated humic acid can be generated within 60 minutes. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which can save half of the en...

Embodiment 3

[0030] With the unactivated powdery weathered coal A of 3.8Kg and the activator B of 0.19992Kg, wherein the sodium oxide and potassium oxide weight that activator B contains account for 80% (mass ratio) of total solid activator B, the barium oxide contained And the quality of basic oxides such as manganese oxide and calcium oxide accounts for 20% (mass ratio) of total solid-state activator B. Mix A and B thoroughly. Then, add 0.0008Kg synergist (composed of one or two kinds of nano-copper and nano-iron metal particles) to the mixture of A and B. At last, the above-mentioned mixture is put into a ball mill, and the rotating speed of the ball mill is adjusted to be 60r, and the time Activated humic acid can be generated within 90 minutes. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which...

Abstract

The invention relates to a method for activating humic acid through physical and chemical combined solid-phase ball milling. The method comprises the following steps: firstly, smashing the weathered coal containing inactivated humic acid and filtering through a 60-mesh sieve, thereby acquiring powdered weathered coal A; adding a solid activating agent B and a synergist C into the weathered coal A and uniformly mixing; putting A, B and C into a ball mill; and setting a rotating speed at 60-80rpm and ball-milling for 60min-90min, thereby acquiring an activated product rich in humic acid. Compared with the traditional chemical activating method, the method has the advantages that more than 50% of energy consumption is saved and no dust or harmful gas is discharged; under the effect of the synergist, the humic acid with a micro-molecule structure is easily generated; the stimulation effect on crops and the improving effect on soil are further benefited; and the method is a low-cost, high-efficiency and environment-friendly activating method.

Description

[0001] (1) Technical field [0002] The invention relates to a method for activating humic acid by combining physical and chemical solid-phase ball milling, and belongs to the field of agricultural resource recycling. [0003] (2) Background technology [0004] Humic acid is a complex mixture colloid composed of natural polymeric hydroxycarboxylic acids, and its basic structural units are condensed aromatic rings and aliphatic groups. Humic acid mainly exists in soil and water as well as lignite. However, the percentage content of humic acid in soil and water is very low, and the main source of humic acid in industry is peat and lignite. Humic acid can promote the ability of crops to absorb water and nutrients, improve the utilization rate of fertilizer nutrients, enhance crop resistance, improve crop quality and improve the physical and chemical properties of soil, etc. [0005] my country's weathered coal resources are widely distributed and have large reserves. Many provin...
