Abstract
The invention discloses a special spraying device for slow-release fertilizer coating. The device is characterized in that an internal warm-air tube (14) is arranged in an external warm-air tube (15), an inner end of the internal warm-air tube (14) is arranged in the external warm-air tube (15), an external end thereof is arranged on a baking zone; a discharge box (23) is communicated with a charging box (16) by an induced draught fan (18); and a concurrent heating fan (4) is communicated with a feed box (7). The internal warm-air tube directly transmits a great amount of heat energy provided by a hot blast stove to the baking zone. The rest hot air discharged from the hot blast stove enters a preheating zone from a circular passage between the internal warm-air tube and the external warm-air tube, and the hot air from a concurrent heating air tube and an air return tube also enters the preheating zone, which provides the preheating zone with an appropriate temperature environment. Materials absorb heat in the preheating zone, the hot air enters an coating zone after temperature drop; as the temperature is lower, fertilizer granules can not be dried rapidly after liquid spraying, good viscosity is kept on granule surfaces, which is beneficial to sticking powder and can prevent mutual adhesion of the granules and avoid hardening of finished products.
Description
Technical field
The present invention relates to a kind of specific equipment that is used on the slow release fertilizer production line, specifically, is a kind of special equipment for slow release fertilizer coating powder spraying.
Background technology
During slow release fertilizer was produced, fertiliser granulates was moved to exit end gradually by inlet end in the passage of a rotation.The fertiliser granulates of ingress generally is a normal temperature, need be preheated to 50-60 ℃ at the passage leading portion, carries out the sustained release dosage coating then, at last at the antiseized powder of coated fertilizer surface sprinkling one deck preventing between the particle adhesion mutually, and under 70-80 ℃ of condition, dry discharging.
Current production devices is introduced the hot blast of hotblast stove from described passage feeding mouth, discharge from discharge port, hot blast temperature from feeding mouth to discharge port reduces gradually, its subject matter that causes is, too high from hydrojet (sustained release dosage) to the stage material envrionment temperature of living in of dusting, occur the rapid-curing cutback phenomenon after the hydrojet, the particle of band sustained release dosage is difficult for bonding antiseized powder, has adhesion between the slow release fertilizer particle of being produced.On the other hand, if hydrojet is controlled at suitable temp to the stage of dusting, the temperature of preheating zone and baking zone then can be on the low side, do not reach preheating and baking needed temperature.
On the other hand, the heat energy utilization rate of existing equipment is on the low side, not only wastes a large amount of thermals source, and causes than serious environmental and pollute.
Summary of the invention
The object of the present invention is to provide a kind of special equipment for slow release fertilizer coating powder spraying, in order to overcome the defective of existing installation.Technical problem to be solved is that the pipeline distribution by hot blast makes preheating zone, coating district and baking zone have the temperature of its arts demand, to improve the coating powder spraying quality; And make full use of the heat of hotblast stove, reduce energy consumption.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of special equipment for slow release fertilizer coating powder spraying comprises the material channel with cylindric inner chamber, and this material channel ingress is connected with material feeding box, and the exit is connected with feed box; The material feeding box upper end is connected with charging box; The material feeding box outer end is also by external hot air pipe coupling hotblast stove; In material channel, also be provided with the sparge pipe and the inner dischage tube that has dust nozzle of inner band jet head; Also comprise the sustained release dosage still that is positioned at the material channel top;
It is characterized in that: at the material channel inwall annular back-up ring plate is installed, the space between this back-up ring plate and the material channel feeding mouth is the preheating zone, and sparge pipe and dischage tube all pass this preheating zone; Material channel space between jet head and the dust nozzle is hydrojet coating district; Dust nozzle is a baking zone to the material channel space between the feed box;
Be provided with interior heating duct in described external hot air pipe, heating duct the inner is arranged in the external hot air pipe in this, and the outer end of interior heating duct is positioned at described baking zone;
Feed box is connected with induced draft fan by reclaiming airduct, and induced draft fan is communicated with charging box by backwind tube, and volume damper is installed on backwind tube;
Also be provided with the concurrent heating blower fan, the air intake port of this concurrent heating blower fan is communicated with hotblast stove, and the air-out port is communicated with material feeding box.
Described sustained release dosage still has sandwich structure, circulation is useful on the hot water that material in the still is carried out heating in water bath in this interlayer, described circulating hot water is by cross current hot water interlayer, and described hot water interlayer is the annular water chamber that is coated on outer layer of plate of external hot air pipe and the formation of external hot air pipe outer wall.
Positively effect of the present invention is:
1), by interior heating duct is set, a large amount of heat energy that hotblast stove is provided are delivered directly to baking zone, guarantee the comparatively high temps that baking zone is required.Another part hot blast of discharging from hotblast stove enters the preheating zone from the circular channel between interior heating duct and the external hot air pipe, and the hot blast of concurrent heating airduct and backwind tube also enters the preheating zone, makes the preheating zone have proper temperature environment.In the preheating zone, material absorbs heat, and the hot blast after the cooling enters the coating district, because temperature is lower, is unlikely to rapid-curing cutback after the fertiliser granulates hydrojet, and the particle surface sustained release dosage keeps excellent adhering, is beneficial to sticking powder.Can also prevent between the particle adhesion mutually, avoid the finished product problem that hardens.This design has also made full use of the waste heat of hot blast, has saved the energy.
2), the sustained release dosage reactor needs heating.The present invention utilizes the heat energy of hot air duct, adopts the method for circulator bath to give the heating of sustained release dosage reactor, makes the entire equipment more compact structure, and layout is more reasonable, and the heat energy utilization rate is higher.
3), the material channel inwall installs annular retaining ring, preheating zone and coating are distinguished.The barrier effect of annular retaining ring stops the sufficiently long time fertiliser granulates in the preheating zone, be convenient to abundant preheating.
