Decomposability granular pattern sulfur fertilizer and its manufacture that the bentonite of the sulfur of～93 weight % and 7 weight %～12 weight % is constituted
Method.
Background technology
Sulfur (sulphur) is very big to the contribution to yield of crop as the one kind in main and necessary nutrient for plants.
It was reported that claiming, sulfur is not only the constituent of three kinds of aminoacid in breeding plant, i.e. cystine, cysteine, methionine,
And be necessary composition in the nodule formation of legume, can suppress breeding plant when the composition is lacked, and this into
Point for crops harvest and quality also have much relations.In addition, the great advantage of sulfur fertilizer is to adjust the acidity of soil
Save to be adapted to the acidity that crop breeds, so as to increase soil fertility.
But, the fusing point of sulfur is 118 DEG C, insoluble in the water of room temperature, therefore there is inconvenience when for agricultural.
In order to improve the problem of this sulfur, attempt mixing additional composition in sulfur and producing corpuscular sulfur fertilizer
Material, but conventional mixing is stirred long lasting for ground in the larger cylinder (Pit) of blender and impeller is provided with, from
And many batches of (one batch) manufactured.But as mentioned above by character two kinds of materials different from each other in batch fashion
During being mixed, in cylinder interior deposited phenomenon is caused, and also consume many times.And, although long-time is carried out
Mixing, can not realize uniform mixing, and the molding to subsequent handling brings harmful effect due to agglomerating phenomenon.
Therefore, require that a kind of the uniform mixed of additional composition for realizing that character is different of exploitation is incorporated in the sulfur decomposed in water always
Sulphur fertilizer and its manufacture method.
The content of the invention
In this regard, the result diligently studied in the present inventor, it was found that by sulfur and bentonite (Bentonite) with about 9：1
The granular pattern sulfur fertilizer that manufactured than being mixed under given conditions of weight there is decomposability in water (quick-acting eased up
Effect property), possess excellent characteristic as the fertilizer of crop, and it is also excellent as soil conditioner, this completes the present invention.
It is an object of the present invention to provide a kind of sulfur and 7 weight %～12 weights by 88 weight %～93 weight %
Decomposability granular pattern sulfur fertilizer (the Soluble flake typed sulphur that the bentonite of amount % is constituted
fertilizer)。
Another object of the present invention is to, there is provided by the sulfur and 7 weight %～12 weights of 88 weight %～93 weight %
The manufacture method of the decomposability granular pattern sulfur fertilizer that the bentonite of amount % is constituted.
In order to realize the purpose of the invention described above, the present invention provides the manufacture method of decomposability granular pattern sulfur fertilizer, should
Method comprises the steps：
I) after is filtered with 5 mesh～20 mesh the sulfur of liquid, with the quality stream of 4000Kg/hr～10000Kg/hr

(Inline mixer), while the bentonite for supplying powder with the feed speed of 300Kg/hr～1360Kg/hr.
In the present invention, the character of sulfur is liquid condition, and bentonitic character is solid (powder).
Before supply, the fusing point of the sulfur of liquid is 118 DEG C, therefore in order to maintain molten condition, makes the cylinder of storage
(Pit) seethe with excitement always.
The sulfur of liquid is gone into the removal of impurity so that about 5 mesh～20 mesh are filtered.
With regard to blender, specifically do not limited, but preferably use in series-operation possess water level signal show (LI),
Temperature signal shows that (TI) and flow signal show the blender of (FI), agitator and exhaustor.
Liquid-state sulfur is with mass flowrate (the Mass flow rate, it is considered to the ratio of sulfur of 4000Kg/hr～10000Kg/hr
Weigh 1.8) (flow rate about 2.2 tons/hr～about 5.6 ton/hr) and be supplied to blender, when mass flowrate is more than 10000Kg/hr, supply
Excessively produce in blender to amount and overflow blocking (Plugging) phenomenon of (Over flow) phenomenon and pipeline, and work as matter
When amount flow rate is less than 4000Kg/hr, quantity delivered is reduced, and uniform mixing can not be realized in blender.
With regard to the bentonite of powder, although be not limited to this, but it is preferably at jumbo bag (Ton Bag) in series-operation
Unloading (Unloading) system in measured and automatically engaged blender.
The bentonite of powder is supplied with the feed speed of 300Kg/hr～1360Kg/hr, when feed speed exceedes
