Description
Technical field
The utility model relates to a kind of granulation formation device of composite fertilizer, the wind-cooling crystallization granulation equipment of especially a kind of full-fusing composite fertilizer, the novel tower-type air-cooled prilling granulator of specifically a kind of full-fusing composite fertilizer.
Background technology
In recent years, the production technology that China produces full-fusing composite fertilizer (being NPK composite fertilizer) is greatly improved, it is ripe day by day that traditional handicrafts such as material, drum granulating are made in traditional disk granulation, extruding, but traditional handicraft exists efficient low, a series of problems such as finished product appearance poor, energy consumption height, and people have invented the tower granulation new technology for this reason, the produced product appearance of this technology is mellow and full, nutrient is accurately even, and the utilization rate of fertilizer height is promptly popular once releasing.But the subject matter that this technology exists is in order to increase cooling effect, its body of the tower is mostly more than 100 meters, tower diameter is also more than 12, investment is big, the cost height, floor space is big, to the safety requirements height, the conveying of material and lifting difficulty are very big, and energy consumption is also than higher, for this reason, people have done big quantity research on tower height and energy consumption, for this reason, Chinese patent 021349711 has proposed a kind of low tower production technology and equipment, Chinese patent 200510038702.X has proposed a kind of freezing process for granulating and device thereof of utilizing, and they are reducing all creative meaning on the body of the tower height.Still there are following problem in actual use in these two kinds of methods and device: the one, increased dust, and dust is easy and the adhesion of tower wall, needs regularly to stop production cleaning; The 2nd, the outward appearance degree of finished particle is relatively poor, can't compare favourably adhesion easily between the particle with high tower; The 3rd, bad adaptability, the prescription of the composite fertilizer that each granulation tower can be made changes can not be too greatly, otherwise can't operate as normal, and the product of different formulations is regulated difficulty; The 4th, invest still bigger.Just because of above-mentioned reason, cause them to be difficult to large tracts of land and promote the use of.At the problems referred to above, the applicant has applied for that to State Patent Office name is called " wind-cooling crystallization granulation method of full-fusing composite fertilizer and device thereof ", application number is that 200710004177.9 patent of invention has solved the problems referred to above to a certain extent, has promoted the manufacturing process and the level of China composite fertilizer greatly.But in actual use because the wind that air blast produces can cause certain turbulent flow in tower, influence the granulation effect, particle diameter is difficult to surpass more than 2 millimeters, and control accuracy had relatively high expectations, easily produce sticking wall dust, cause easy caking, the product proportioning is regulated problems such as difficulty, therefore must be improved.
Summary of the invention
The purpose of this utility model is the granulating weak effect that exists at existing tower granulation, easily produce sticking wall dust and product proportioning regulates the big problem of difficulty, design a kind of shaping well, small investment, energy consumption low, be suitable in the wind-cooling crystallization granulation device of the full-fusing composite fertilizer that uses of low tower.
The technical solution of the utility model is:
The wind-cooling crystallization granulation device of a kind of full-fusing composite fertilizer, comprise granulation tower 1 and rotating granulation head 2, the tower height of this granulation tower 1 is a 15-70 rice, tower diameter is a 6-18 rice, rotating granulation head 2 is installed in granulation tower 1 inside top center position, the bottom of making material tower 1 is connected with one taper (V-arrangement) or W shape structure (front view) gatherer 4, it is characterized in that being equipped with one at least at the top of described granulation tower 1 encloses air exhauster 3, the air inlet of this air exhauster 3 communicates with the inner chamber of granulation tower 1, and the distance L of Edge Distance granulation tower 1 inwall of outmost turns air exhauster 3 is 0.9-2.5m; In the bottom of granulation tower 1, to offer a circle height H be the air-inlet window 5 of 1.2-3m for the top of conical collector 4; Conveying device 6 is installed, the rotary drum cooler 7 that the discharge end of conveying device 6 is installed below the discharging opening of conical collector 4.
Louvered window leaf 8 is installed on described air-inlet window 5.
The charging aperture of described rotating granulation head 2 links to each other with the discharge end of slip breakdown of emulsion machine 9.
The beneficial effects of the utility model are:
1, thereby it is of the present utility model by changing the prilling process that traditional air blast delays the quick cooling formation of high temperature fluid column decrease speed particle, change the method for exhausting into, make cooling air stable the flowing that make progress at the bottom of the tower, not only can further prolong high temperature fluid column decrease speed, and because unstable airflow, the granulation effect is better than the air blast mode greatly, can obtain particle diameter in the composite fertilizer more than 2.5 millimeters, particle diameter can be steady in a long-term between the 2-4.5 millimeter, supporting rotary drum cooler makes the whole cooling of particle to the particle that falls dehumidifying wind cooling processing from cooling tower simultaneously, and is non-hygroscopic in the cooling procedure, prevented from caking is convenient to packing and transportation.
2, with existing in low tower compare with freezing tower and can reduce investment 50%-80%, production scale can be regulated as required simultaneously, and is changeable.
3, can produce the composite fertilizer of high, normal, basic variable concentrations, it is very convenient to change prescription, the formula rate scope is big, composite fertilizer for different proportionings can will adjust to suitable scope cool time by variable frequency adjustment device adjusting exhausting amount, prevented that cold-peace from cooling off the not generation of foot phenomenon, and realized simultaneously the convenient of particle diameter regulated.
4, can not produce the dust wall sticking phenomenon, need not periodic cleaning tower wall,, therefore can not produce the dust wall sticking phenomenon because the wind of air exhauster rises along wall.
5, the good evenness of product, yield rate can be up to more than 99%, and handling good.
6, can under all weather conditions, work, solved under high temperature that existing processes exists, the super-humid conditions can't ordinary production contradiction, can be under hot and humid condition round-the-clock ordinary production.
7, energy consumption is low, has reduced tower height on the one hand, has reduced the energy consumption of mass transport, by adopting energy-conservation air exhauster, can significantly reduce energy loss on the other hand.
8, the utility model is equipped with the breakdown of emulsion machine slip is carried out fragmentation, and the emulsification exquisiteness helps increasing the surface tension of temperature of high temperature slurry, improves the granulating effect, increases particle diameter and granulating ratio (more than 99%).
9, it is low to the utlity model has cost, makes that installation, debugging and operation maintenance are convenient, the advantage of good energy-conserving effect.
