Abstract
The invention relates to a disc granulation process for livestock and poultry feces organic fertilizer. The process comprises the steps of feeding, balling, drying, primarily screening, cooling, screening the finished products, coating, packaging and warehousing. The granulation process completely overturns the traditional method of disc granulation process, wherein the to-be-balled materials are firstly watered and then balled directly to avoid the crushing process in the traditional disc granulation process to overcome the deficiency of the severe dust; in steps of primarily screening and screening the finished products, the oversized and undersized balled granules, which do not meet the specifications, return back to the disc granulator again to be subjected to a balling process to achieve the purpose that the finished products have basically consistent sizes; the drying process is immediately after the balling process, since the cooling time is very long, accidentally crushed balled granules can be checked out in steps of primarily screening and screening the finished products, furthermore, the physical properties of the balled granules are stable fundamentally in the step of packaging products, the phenomenon of crushing rarely occur, the qualified rate of products is high and the content of dust in a workshop is low.
Description
Technical field
The present invention relates to fertilizer granulation technique, especially a kind of fowl and animal excrement fertilizer disc granulation technique.
Background technology
In the process of growth of agriculture plant, all can use composite fertilizer and fertilizer, traditional compound fertilizer production technology mainly comprises that raw material stirring, raw material granulation, particle are dried, particle is cooling, gradation, finished product coating, finished product packing etc., now there is a kind of novel process about propylhomoserin producing composite fertilizer by liquor jetting pelletting in market, comprises batching, whitewashing, granulation, oven dry, cooling, screening, metering, finished product detection; When before granulation, preparation propylhomoserin solution is to raw material granulation, whitewash: in ammonia water tank, strong aqua washing water are diluted to 20% weak ammonia, send into tubular reactor through aqua ammonia pump pressurization; 98% vitriol oil after being pressurized to, sulfuric acid pump is sent into tubular reactor; Weak ammonia react in tubular reactor with sulfuric acid 50～60 second ammonification acid solution, in propylhomoserin solution, add urea, water to be mixed into viscosity slurry, viscosity slurry Direct Uniform is sprayed on the bed of material in tablets press; Control material pH value 5.8-6.3, granulation routinely, oven dry, cooling, screening, metering, detection, finished product are put in storage.
Produce exquisite fertilizer and complex fertilizer product and all require granulation, granulation process on producing at present has disc granulation and drum granulating, especially disc granulation technique need to dry raw material pulverize in advance, carry out again granulation, the dust producing in the time pulverizing is very serious, and the balling-up rough produced of present fertilizer disc granulation technique, not of uniform size, there is frangible defect, and all do not have for a long time industry personage to capture always.
Summary of the invention
The object of the invention is, in order to solve the existing defect of fertilizer disc granulation technique in prior art, provide a kind of balling ratio high, and the size of balling-up material to be substantially all consistent, be difficult for the fowl and animal excrement fertilizer disc granulation technique of pulverizing.
To achieve these goals, the technical solution used in the present invention is:
A kind of fowl and animal excrement fertilizer disc granulation technique, comprises the steps:
A, material loading: fowl and animal excrement after treatment is directly transported in raw material feed bin and also classifies fowl and animal excrement is added in the rotating-disk of granulating disc uniformly;
B, balling-up: by liquid ingredient or appropriate water via the liquid ingredient sparger sprinkle of granulating disc on the material in disk, to meet the required amount of liquid phase of balling-up; The disk of rotation and web produce frictional force and centrifugation to material, make material produce circumferential movement, make rubbing and extruding mutually between powder, and the balling-up of reuniting is gradually until increase to and be enough to overcome interparticle frictional force and dished out outside dish;
C, oven dry: the balling-up mass transport of being dished out outside dish, to fertilizer dryer, is carried out to heat exchange with the hot blast from hotblast stove.
D, preliminary screening: by the balling-up mass transport of oven dry, to the balling-up material that sub-elects fine particle in hot sieve apparatus, the balling-up material of fine particle is directly returned in granulating disc, continue to participate in the balling-up of sticking of particle as core.
E, cooling: balling-up mass transport qualified screening is to fertilizer cooler, cooling by natural cold wind or pressure cold wind;
F, finished product screening: cooled balling-up mass transport, to finished product screen extension set, is therefrom filtered out to balling-up material up to specification, remaining macrobead balling-up material is back to after pulverizer is pulverized to continuation in granulating disc and participates in balling-up.
G, film: the qualified balling-up product after screening is delivered to the processing of coating machine film.
H, packing warehouse-in: weigh, pack, put in storage being delivered to fully-automatic packaging scale through the qualified balling-up product of film processing.
Above-mentioned a kind of fowl and animal excrement fertilizer disc granulation technique, in described baking operation, the temperature of hot blast is 30 ℃-80 ℃.
Above-mentioned a kind of fowl and animal excrement fertilizer disc granulation technique, the dust in workshop is through tornado dust collector, labyrinth type dust settling chamber, wet scrubbing tertiary treatment.
Beneficial effect of the present invention is: this disc granulation technique is mainly to produce into the fertilizer of ball particle for fowl and animal excrement, this granulation process has been overturned traditional disc granulation processing method completely, first be the processing of sprinkling water of the material for the treatment of balling-up, then directly carry out balling-up operation, avoid the pulverizing process of traditional disk granulation process, overcome the serious defect of dust, carrying out in the operation of preliminary screening and finished product screening, excessive with too small become ball particle to return in granulating disc, again to carry out balling-up operation by what fall short of specifications, reach the basically identical object of finished product size, and baking operation is immediately after balling-up operation, cooling is chronic, occur that the unexpected one-tenth ball particle of pulverizing will be examined out in preliminary screening and finished product screening process, in the time carrying out the packing of product, become the physicals of ball particle substantially in stable, occur that the phenomenon of pulverizing is considerably less, the qualification rate of product is high, in workshop, dust content is low.
Accompanying drawing explanation
Fig. 1 is process flow chart of the present invention.
Embodiment
For making that constitutional features of the present invention and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of fowl and animal excrement fertilizer disc granulation technique, comprises the steps:
