Abstract
The invention specifically discloses a humic acid compound fertilizer production process, which solves the problem that the traditional humic acid fertilizer is low in granulation rate, high in cost and complicated process operation in the process of granulation. The humic acid compound fertilizer production process comprises the following steps of: adding ammonium chloride, urea, potassium chloride, monoammonium phosphate, a humic acid and a desulfurized gypsum into a mixer to uniformly mix in proportion; conveying the uniformly-mixed raw materials to a granulating disc, and feeding a right amount of steam, so that the mixture is granulated; and realizing granulating after carrying out drying, cooling and screening on the semi-finished products. Compared with granules produced by using other methods, granules of products produced by using the process disclosed by the invention are more uniform in size, higher in spherical degree and stronger in granule hardness, and the granulating rate can reach 65-85%, so that the production capacity of enterprises is improved, and the recycling of wastes is realized, and therefore the process is environmental-friendly.
Description
Technical field
The invention belongs to the agrochemical technical field, be specially a kind of production technique of Remixed humic acid fertilizer.
Background technology
Research both at home and abroad thinks that Remixed humic acid fertilizer has combined the quick-acting of inorganic fertilizer and the slow-releasing two big characteristics of fertilizer, and there is important effect raising crop yield, chemical fertilizer utilization ratio aspect.In addition; The humic-acid kind organic matter derives from soil; Being a kind of nutritive substance, is again the important composition composition of soil granular, can not only combine to form the water stability soil aggregate with divalent cation calcium, magnesium, manganese, bridging material such as ferrous; And have the function of adsorption of nitrogen and potassium, activation phosphorus, so Remixed humic acid fertilizer is significant at the structure of improving the soil, aspect such as increase soil fertility.
At present, Remixed humic acid fertilizer needs to add amount of water and satisfies the granulating needs in the process of disk granulation.Humic acids is the more raw material of a kind of moisture content; Very easily become mud in the granulation process or become oarse-grained phenomenon; Cause production technique wayward, product particle unstable properties (hardness little, be prone to harden) has directly influenced the application prospect of organic-inorganic compound mixed fertilizer.
Several kinds propose to produce humic acid type compound fertilizer with Attapulgite viscosity amendment among the Chinese patent CN101967072A.Attapulgite contains a large amount of aluminium elements, and harmful to plant growth, consumption is big, increases the granulation cost.Chinese patent CN101684051A discloses a kind of production technique of mixed organic manure.Raw material gets in the rotary drum granulator after fragmentation, adds entry, steam, the auxiliary granulation of urine, and the material that rotary drum granulator comes out gets into granulating disc again and continues granulation, again product is dried screening.The secondary granulation operational process of craft is complicated, and the granulation time is long, and throughput is low.
Summary of the invention
Traditional Remixed humic acid fertilizer granulating rate in granulation process is low, cost is high, the technological operation complicated problems in order to solve in the present invention, and a kind of production technique of Remixed humic acid fertilizer is provided.
The present invention adopts following technical scheme to realize: the production technique of Remixed humic acid fertilizer, comprise the steps,
(1) ammonium chloride, urea, Repone K, monoammonium phosphate, humic acids, desulfurated plaster are added in the whisking appliance in proportion stir, wherein the ratio of quality and the number of copies of ammonium chloride, urea, Repone K, monoammonium phosphate, humic acids, desulfurated plaster is 37 ~ 40:11 ~ 12:6 ~ 7:17:22:3 ~ 6;
(2) raw material that stirs is sent into granulating disc, feed an amount of steam, make the mixture granulating, the control prilling temperature is at 60 ~ 80 ℃, and wherein the diameter of granulating disc is that 2.4m, obliquity are that 40 ~ 45 °, rotating speed are 400rad/min;
(3) above-mentioned work in-process choose after through oven dry, cooling, screening particle diameter be the particle of 3 ~ 4.75mm as finished product, the inlet temperature of wherein drying used dryer is 140 ~ 170 ℃, temperature out is 50 ~ 60 ℃.
Beneficial effect of the present invention is following:
1, big, the high adsorption capacity, dispersed high of the viscosity of desulfurated plaster, in granulated process, frictional force and cohesive force between the particle are bigger; Symbiosis in succession each other; Staggered overlap joint has reduced moisture content of raw material, has improved granulating rate and pellet hardness; The water cut of product particle < 1%, pellet hardness>28N.
2, desulfurated plaster is power plant's waste, as solid additive, and the desulfurated plaster wide material sources, consumption is few, can reduce the use of non-renewable Mineral resources such as attapulgite, reduces the production cost of chemical fertilizer; And the second stage employ of the up to a million tons of discarded desulfurated plasters in power station, can solve the problem that a large amount of desulfurated plaster solid waste is banked up land occupation, realized the resource circulation utilization.
3, owing to adopted desulfurated plaster; The ratio of quality and the number of copies of each raw material is preferred through a large amount of experiments back among the present invention; Cooperate the reasonable control of prilling temperature; Cooperate the reasonable step of selecting suitable granulating disc, selector disc tablets press obliquity and rotating speed, selection oven dry, cooling and screening for use, realized the good production effect.
4, the product particle of the present invention's production is than the additive method particle size is more even, roundness is higher, pellet hardness is stronger, and granulating rate can reach 65% ~ 85%, has improved the throughput of enterprise.
