Abstract
The utility model discloses a device for preparing granular compound fertilizer, which comprises a prilling tower, a granulator and a urea dissolver, wherein the granulator is located on the top portion of the prilling tower, and the urea dissolver is connected with the granulator. The device is characterized in that the bottom portion of the prilling tower is connected with an air cooler, the other end of the air cooler is connected with a compulsory air supply unit which is connected with a refrigerating unit, the refrigerating unit is connected with an exhaust fan, the other end of the exhaust fan is connected with a dust collector, and the dust collector is connected with the upper portion of the prilling tower. The device for preparing granular compound fertilizer has the advantages of excellent granulation effect, low energy consumption, low maintenance, low producing cost, less waste discharge, energy conservation and environmental protection.
Description
Technical field
The utility model relates to composite fertilizer and makes field, a kind of specifically equipment for preparing granular complex fertilizer.
Background technology
Existing tower granulation composite fertilizer technology, adopt the natural ventilation process for cooling, molten slurry is from very high prilling tower top free-falling, the time that the high-temperature material small droplets that is sprayed is stopped in tower is limited by tower height, make fertiliser granulates cooling curing fully, thereby granulating rounding not, what have is oblate spheroid shape or sheet, that have or even Powdered.Simultaneously because cooling fully of high-temperature material, as easy as rolling off a log at tower bottom big hopper or material scraper on a large amount of condensation cure, have a strong impact on ordinary production.Particularly at summer high temperature or overcast and rainy moist weather, a large amount of moisture absorptions are hung the globule on the big hopper of inner wall of tower and tower bottom and the material scraper, make discharging suction deliquescence at the bottom of the tower, fertilizer dissolves seriously, gained moisture content of finished products severe overweight, packing back caking is serious, serious causes stopping production at this problem, some increases prilling tower, some tower height surpasses 120 meters, though make situation obtain certain alleviation, Installed capital cost improves greatly, the also corresponding raising of production run cost simultaneously, and fundamentally do not solve summer high temperature, overcast and rainy humid climate causes fertilizer to dissolve, the problem of caking.
Summary of the invention
A kind of granulation is effective, finished product is insoluble, the equipment of non-caking preparation granular complex fertilizer in order to provide for the purpose of this utility model.
The technical scheme that realizes the foregoing invention purpose is as follows:
The equipment of preparation granular complex fertilizer; comprise prilling tower; be positioned at the tablets press at prilling tower top and the urea dissolver that is connected with tablets press; described prilling tower bottom connects a cold blast engine; the cold blast engine the other end connects the forced air supply unit, and the forced air supply unit is connected with a freezing unit again, and freezing unit connects vacuum fan; the vacuum fan the other end is connected with fly-ash separator, and fly-ash separator is connected to the top of prilling tower.
Described tablets press comprises two motors, be connected with turning axle by transmitting gear with individual motor, another motor by transmitting gear be enclosed within the revolution outer shaft and be connected, the bottom of axle sleeve is provided with shower nozzle.
Described urea dissolver is that horizontal-type biaxial stirs, and heating tube wherein is the multilayer tubulation.
The utility model is forced cold wind by introducing, the convection current cooling, and there is not returning charge in a granulating moulding, and throughput is improved greatly, has avoided defect low because of traditional prilling tower granulating rate, that returning charge is many, saves the energy, improves plant factor.Because of no returning charge dust pollution, Working environment is more cleaned simultaneously, avoided three waste discharge.Tablets press of the present utility model has saved the machine envelope and the inside and outside dual-purpose bearing of the easiest damage of existing tablets press; increased the durability of equipment; and the rotating element after improving no longer contacts with high temperature heavy-gravity slip; make its care and maintenance convenient simple; increase the service life, reduce the parking maintenance frequency.The used urea dissolver of the utility model is stirred by existing vertical single shaft and changes the horizontal-type biaxial stirring into, and change the heating of original coil tube type into multilayer shell and tube heat transfer tube, adopt direct solid heating, urea liquid after dissolving is separated from the dissolver bottom fast, thereby reduced contacting of liquid area and high temperature coil pipe, reduced the generation of side reaction, improved the quality of composite fertilizer, reduce the raw material consumption loss that urea decomposition causes simultaneously, reduced the discharging of toxic and harmful.
