Description
Technical field
The utility model relates to fertilizer coating technical field, particularly relates to a kind of fertilizer coating fluidized-bed.
Background technology
Among the fluid a large amount of solid particulate being suspended in motion, thus make particle have some appearance features of fluid, the solid contact condition of this stream is called fluidization of solid, i.e. fluidized-bed.
Fertilizer coating technology is that to reach the technology of slowly-releasing object, coated fertilizer is also known as coated fertilizer, film fertilizer at fertilizer surface parcel thin film.The fertilizer of quick-acting chemical fertilizer granule is wrapped up with semipermeability or opacity film substrate.Filmogen has plastics, resin, paraffin, polyethylene and elementary sulfur etc.The object of coating is that the available nutrient of coated fertilizer the inside after being manured into soil is discharged, lentamente to extend fertilizer efficiency.
In existing fertilizer coating technology, lacking one can continuous seepage, the production unit that fertilizer coating is effective.
Utility model content
The purpose of this utility model is the defect existed for prior art, proposes a kind of fertilizer coating fluidized-bed, and this fluidized-bed is used for fertile grain coating, can feeding in continuous material and discharging, and production efficiency is high, and fertile grain completes coating in fluid mapper process, and coating is effective.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of fertilizer coating fluidized-bed, it is characterized in that: comprise fluidisation cylindrical shell, described fluidisation cylindrical shell connects, feed system, discharge system, hot air circulating system and coating agent feeder system, in described fluidisation cylindrical shell, intersegmental part is fluidisation coating chamber, the bottom in fluidisation coating chamber arranges two pieces of steel meshes to folding, several coating guide shells are set above steel mesh, coating guide shell is vertically arranged, leaving between coating guide shell lower end and steel mesh can the gap passed through of fertilizer grain, the upper and lower two ends of coating guide shell are not set up separately and are set up shower nozzle and lower nozzle, upper nozzle sprays downwards from coating guide shell upper end, lower nozzle upwards sprays from coating guide shell lower end, the mid-way in described fluidisation coating chamber is also provided with pod, described steel mesh is that the through hole processing annular spread on steel plate forms, and the through-hole diameter arranged in border circular areas corresponding with coating guide shell on described steel mesh is greater than the through-hole diameter in other region.
Described feed system is connected to the left side of fluidisation cylindrical shell, and discharge system is connected to the right side of fluidisation cylindrical shell, and hot air circulating system and coating feeder system are connected to the rear end of fluidisation cylindrical shell, and the front end of described fluidisation cylindrical shell is provided with viewing window.
Described lower nozzle is arranged on steel mesh.
Described coating guide shell arranges six altogether, and six coating guide shells are around the circular distribution in center in fluidisation coating chamber.
The blast pipe of hot air circulating system passes into hot blast from fluidisation cylindrical shell lower end, and the air outlet tube of hot air circulating system discharges cold wind from fluidisation cylindrical shell upper end, and hot blast is from the bottom to top through fluidisation coating chamber, and fertile grain blows afloat by the hot gas flow of formation, reaches the effect of fluidisation; Fertile grain is with while hot gas flow flowing, and the coating agent of upper nozzle and lower nozzle ejection atomization, coating agent is at granule surface stroke dressing.In order to improve coating effect further, the present invention arranges coating guide shell, pod in fluidisation coating chamber, and through hole is provided with on steel mesh, object allows the regular flowing in fluidisation coating chamber of fertile grain exactly, making the fertile grain flow trace forming multiple partial circulating in fluidisation coating chamber, is coating district in coating guide shell.
The through-hole diameter arranged in the steel mesh region that coating guide shell lower end is corresponding is larger than the through-hole diameter in other region on steel mesh, hot gas flow is less through wide aperture through hole resistance, when having fertile grain above steel mesh, hot gas flow can through wide-aperture through hole drive fertile grain from coating guide shell to upper flowing, the through-hole aperture arranged due to the steel mesh below coating guide shell is larger, under airflow function, negative pressure can be formed in coating guide shell, the fertile grain of periphery, coating guide shell lower end can be drawn through, thus the fertile grain circulation track that formation one is little inside and outside coating guide shell, when fertile grain from bottom to top flows in coating guide shell, upper nozzle, lower nozzle sprays coating agent simultaneously in coating guide shell, it is fixing coating region in coating guide shell, fertile grain velocity of flow in coating guide shell is very fast, and speed is comparatively stable, fertile grain amount by coating guide shell in unit time is also comparatively stable, the quality of fertile grain coating can be improved, the uniformity coefficient of fertile grain coating, the gauge control of coating, all more accurate.The central position that the fertile grain fallen can be avoided to drop on fluidisation coating chamber that arranges of pod forms circulation dead point, and fertile grain can be made to drop on from the position close to coating guide shell lower end, is convenient to be inhaled in coating guide shell form circulation.
Steel mesh is involuted by two pieces of semicircular splits, and two pieces of semicircular splits can overturn downwards opens, and is unloaded by the fertile grain after coating.
The beneficial effects of the utility model are:
A kind of fertilizer coating fluidized-bed that the utility model provides, in the fluidisation coating chamber of this fluidized-bed, several coating guide shells are set, fertile grain forms little fertile grain circulation track with hot gas flow inside and outside coating guide shell, fertile grain is completing coating by time in coating guide shell, each coating guide shell forms a little fertile grain circulation track, fertile grain coating is effective, can not form circulation dead point, the good evenness of fertile grain coating.
