Description

Sol particle type sulphur fertilizer and manufacture method thereof
Technical field
The present invention relates to sol particle type sulphur fertilizer and manufacture method thereof, more particularly, relate to the sol particle type sulphur fertilizer and the manufacture method thereof that are formed by the sulphur of 88 % by weight~93 % by weight and the wilkinite of 7 % by weight~12 % by weight.
Background technology
Sulphur (sulphur) is as the one in main and necessary nutrient for plants, very large to the output contribution of crop.It was reported title, sulphur is not only three seed amino acids in breeding plant, the i.e. constituent of Gelucystine, halfcystine, methionine(Met), and be necessary composition in the nodule formation of leguminous crop, in the time lacking this composition, can suppress breeding plant, and this composition also there are much relations for harvest and the quality of farm crop.In addition, the great advantage of sulphur fertilizer is to be to be applicable to the acidity that crop breeds by the acidity adjustment of soil, thereby increases soil fertility.
But the fusing point of sulphur is 118 DEG C, insoluble in the water of normal temperature, therefore when for agricultural, there is inconvenience.
In order to improve the problem of this sulphur, attempting mixing in sulphur appends composition and produces corpuscular sulphur fertilizer, but mixing is in the past to stir constantly for a long time in the larger cylinder (Pit) that stirrer and impeller are installed, thereby many batches ofly manufacture (one batch).But during two kinds of materials that as mentioned above proterties differed from one another mix with batch mode, cause deposited phenomenon at cylinder interior, and expended a lot of time.And, although mix for a long time, can not realize uniform mixing, and because agglomerating phenomenon is given the moulding of subsequent handling and brought detrimentally affect.
Therefore, require to develop a kind of evenly mixed sulphur fertilizer and manufacture method thereof of decomposing in water of being incorporated in of appending composition that proterties is different that realize always.
Summary of the invention
To this, in the result of inventor's lucubrate, the granule type sulphur fertilizer of having found sulphur and wilkinite (Bentonite) to mix under given conditions with the weight ratio of about 9:1 and manufacture has solubility (quick-acting and slow) in water, possesses excellent characteristic as the fertilizer of crop, and also excellent as soil improvement agent, complete thus the present invention.
The sol particle type sulphur fertilizer (Soluble flake typed sulphur fertilizer) that provides the wilkinite of a kind of sulphur by 88 % by weight~93 % by weight and 7 % by weight~12 % by weight to form is provided.
Another object of the present invention is to, the manufacture method of the sol particle type sulphur fertilizer being made up of the sulphur of 88 % by weight~93 % by weight and the wilkinite of 7 % by weight~12 % by weight is provided.
In order to realize the object of the invention described above, the invention provides the manufacture method of sol particle type sulphur fertilizer, the method comprises the steps:
I) after liquid sulphur is filtered with 5 order~20 orders, be supplied to stirrer (Inline mixer) with the mass flow rate of 4000Kg/hr~10000Kg/hr, supply with pulverous wilkinite with 300Kg/hr~1360Kg/hr simultaneously;
Ii) in stirrer, sulphur and wilkinite are mixed 0.6 second~6.0 seconds with 3000rpm~3600rpm;
Iii) be shaped to the particle form of suitable size; And
Iv) the particle of moulding is cooled to 1 DEG C~35 DEG C.
step I) supply with
After liquid sulphur is filtered with 5 order~20 orders, with mass flow rate (the Mass flow rate of 4000Kg/hr~10000Kg/hr, consider that the proportion of sulphur is 1.8) (flow rate approximately 2.2 tons/hr~approximately 5.6 ton/hr) be supplied to stirrer (Inline mixer), supplies with pulverous wilkinite with the feed speed of 300Kg/hr~1360Kg/hr simultaneously.
In the present invention, the proterties of sulphur is liquid state, and bentonitic proterties is solid (powder).
Before supplying with, the fusing point of liquid sulphur is 118 DEG C, therefore in order to maintain molten state, the cylinder (Pit) of storage is seethed with excitement always.
Liquid sulphur is filtered with approximately 5 order~20 orders and remove impurity.
About stirrer, specifically do not limit, possess but preferably use the stirrer that water level signal shows (LI), temperature signal demonstration (TI) and flow signal demonstration (FI), agitator and vapor pipe in series-operation.
Liquid-state sulfur is with mass flow rate (the Mass flow rate of 4000Kg/hr~10000Kg/hr, consider the proportion 1.8 of sulphur) (flow rate approximately 2.2 tons/hr~approximately 5.6 ton/hr) be supplied to stirrer, in the time that mass flow rate exceedes 10000Kg/hr, feed rate too much produces obstruction (Plugging) phenomenon of overflowing (Over flow) phenomenon and pipeline in stirrer, and in the time that mass flow rate is less than 4000Kg/hr, feed rate reduces, and in stirrer, can not realize uniform mixing.
About pulverous wilkinite, although be not limited to this, in series-operation, be preferably and in unloading (Unloading) system of jumbo bag (Ton Bag), measure and automatically put into stirrer.
Pulverous wilkinite is supplied with the feed speed of 300Kg/hr~1360Kg/hr, and in the time that feed speed exceedes 1360Kg/hr, feed rate too much causes the color of product dark, makes the moulding variation of next operation.In the time that feed speed is less than 300Kg/hr, feed rate reduces and causes the of light color of product, makes the moulding variation of next operation.
According to the flow rate of liquid-state sulfur as above and pulverous bentonitic feed speed, sulphur-bentonitic ratio of mixture maintains sulphur 88 % by weight~93 % by weight and wilkinite 7 % by weight~12 % by weight.
step I i) is mixed
In stirrer, sulphur and wilkinite are mixed 0.6 second~6.0 seconds with 3000rpm~3600rpm.
Bentoniticly more than 85% formed by montmorillonite (Montmorillonite forms a group of mineral of polynite/clay), therefore, compared with other materials, there is the extra high characteristic of viscosity.Only have the mixing of the material at short notice with this specific character, can improve the effect of mixing.Therefore,, in stirrer of the present invention, transfer within the short period of time (0.6 second~6.0 seconds), liquid sulphur and solid-state wilkinite to be mixed equably with 3000rpm~3600rpm high-speed rotary.
step I is moulding ii)
Use general forming machine and be the suitable particle form of size by the sulphur-wilkinite mixture forming mixing in i) in step I.
About suitable size, limit, but be preferably diameter 2.5mm~5mm, height 1.2mm~1.8mm, and particle form can be beans (pea) form of splitting.
step I is v) cooling
By step I ii) in the sulphur fertilizer of particle form of moulding under 1 DEG C~35 DEG C (room temperature), carry out cooling.
Although be not limited to this, for series-operation, also can by cooling bring carry out cooling.
After cooling step, as required, further implement the step that the sulphur fertilizer of the particle form of manufacture is transferred and measured and packs.
Decompose absorbing when moisture according to the granule type sulphur fertilizer of manufacture method manufacture as above, and in latter 6 months of fertilising sulphur 80% be converted to the SO that crop can absorb 4 -2.When the wilkinite that contains at sulphur fertilizer of the present invention absorbs moisture and when swelling, sulfur granules is decomposed into imperceptibly to the sulphur particle of 20 μ m~200 μ m scopes, and Quick Oxidation and be converted to the available vitriol of plant (sulphate).Granule type sulphur fertilizer of the present invention does not have dust in addition, health and health in the time of fertilising.
As another example of the present invention, provide the sol particle type sulphur being formed by the sulphur of 88 % by weight~93 % by weight and the wilkinite of 7 % by weight~12 % by weight fertilizer.
Wilkinite reduces the resistive of sulphur in bulk (Bulk sulfur), reduces the tendency that sulphur in bulk keeps static charge, thereby reduces the possibility of fire.In sulphur fertilizer of the present invention, if wilkinite is less than 7 % by weight, the speed that absorbs moisture is slow, quick-acting as sulphur-bentonitic characteristic declines, if and wilkinite exceedes 12 % by weight,, because the content of sulphur is relatively low, therefore the necessary nutrient substance of plant reduces, and causes crop to breed slowly.
Manufacturing method according to the invention, realizes homogeneity with accurate mixed effect, and product that can production high-quality, without defoamer, is produced at short notice continuously, therefore can produce in a large number.
Granule type sulphur fertilizer constructed in accordance has and is suitable for quick-acting that crop breeds and the feature of slow.In latter 6 months of fertilising, 80% is converted to the SO that crop can absorb 4 -2form, the pol of raising apple, pears, peach, grape, persimmon, chestnut, oranges and tangerines, plum etc., makes color good, in the crops such as garlic, onion, ginger, increase sulfur-containing amino acid, possess thus unique fragrance, and improve the storage in house, can cultivating high quality agricultural-food.
The sugar and the Vitamin C content that improve the leaf vegetabless such as radish, Chinese cabbage, improve intrinsic taste, productivity gain, and output, starch value, the reducing sugar content of raising potato, with the potato of production high-quality.In addition, improve the crop absorption ratio of phosphorus, potassium, calcium, boron, iron, magnesia, lead etc., and sulphur amount is about 90%, concentration is high, and therefore rate of fertilizer application is few, thereby can save labor force and expense.
