Abstract
The present invention relates to a novel process for preparing granular compound organic fertilizer and a complete apparatus. The present invention is characterized in that the feces of livestock and poultry or other high humidity organic fertilizer raw materials, chemical fertilizer, fertilizer additive components, etc. are evenly mixed in proportion and conveyed into a high humidity material dryer having a granulation function; granulation is finished in the drying process of materials. The present invention has the advantages of simple process and low energy consumption, the proportion of organic components is free from restriction, the flowability of grains of a product is good, and thus, the complete apparatus is suitable for mechanical fertilizer application.
Description
Technical field:
The invention belongs to organic fertilizer industrialization production technology and equipment thereof.
Background technology:
Existing industrialization organic composite fertilizer production technology has two types.A kind of elder generation mixes the organic fertilizer drying by a certain percentage with chemical fertilizer and makes the mix type organic composite fertilizer.Because organic and inorganic component has than big-difference at aspects such as proportion, granularities, finished product easily produce segregation phenomenon, influence result of use.Another kind of elder generation cooperates the organic fertilizer drying again with chemical fertilizer, through special granulating working procedure (pulverizing, metering, mixing, granulation, drying), make the particle organic composite fertilizer, and energy consumption is big, the cost height.Granulating working procedure mainly adopts granulating method and extrusion process.Because xylogen in the organic waste materials, content of cellulose are higher, be difficult to ball up, therefore the adding proportion of organic constituent is lower in the circular granular fertilizer of producing with granulating method, and the advantage of organic fertilizer is difficult to manifest; And used tablets press main parts size life-span of extrusion process is short, and failure rate height, and product is cylindric is mobile poor, easy generation plugging fault during with mechanical fertilization.
Summary of the invention:
The object of the present invention is to provide that a kind of technology is simple, energy consumption is low, each fertilizer components proportioning arbitrarily, the novel organic fertilizer material industrialization production technology and the suite of equipment thereof of product particle good fluidity.
Characteristics of the present invention are fertilizer raw material drying and organic composite fertilizer granulation and drying integrated.This technology does not have specially independently granulating working procedure and relevant device; Fertilizer raw material drying and organic composite fertilizer granulation and drying are carried out simultaneously, and only use same thermal source.
Concrete technology is organic fertilizer such as feces of livestock and poultry, chemical fertilizer, components such as fertilizer additive mix in proportion, send into the broken dryer of cylinder that band is strengthened the granulation structure by transfer roller, under the effect of induced draft fan, the high-temperature medium that hotblast stove produces is negative pressure and enters dryer, make the dry and granulation of mixture, the classified screen sizing of dried particles product, remove big assorted, fine powder returns mixing machine, the particle that particle diameter is fit to is the granular compound organic fertilizer product, dispatches from the factory behind the metering packing, and dryer tail gas is through the fly-ash separator preliminary treatment, discharging after exhaust gas purification system is handled again, the isolated dust of fly-ash separator also returns mixing machine and reenters drying, granulation process.
Suite of equipment of the present invention is made up of drying-granulating machine 1 and mixing machine 2, transfer roller 3, sizing screen 4, metering packaging machine 5, hotblast stove 6, fly-ash separator 7, air sealer 8, induced draft fan 9, exhaust gas purification system 10 etc.Drying-granulating machine 1 is had shredder assembly by inside cylinder 1-1 forms with the cylinder 1-2 serial connection that has reinforcement granulation structure.The transmission system of two cylinders is independent separately.Two inner wall of rotary drum all have the flight 1-1-1 and the 1-2-1 that material can be promoted and scatters.Cylinder 1-1 is connected by transition hopper 1-3 with cylinder 1-2.The version of slide 1-4 is arranged in the transition case 1-3.Shredder assembly 1-1-2 in the cylinder 1-1 is the turning axle that has 8～10 groups of shaft-like breaking units, and it is identical that cylinder 1-1 and shredder assembly 1-1-2 turn to, but asynchronous.Reinforcement granulation structure 1-2-2 in the cylinder 1-2 is at the anterior herringbone flight material stop ring that is provided with of cylinder.
Advantage of the present invention and positively effect:
1, technology is simple, only with a thermal source, with fertilizer raw material drying and organic reaching
Granulation of compound fertilizer and drying integrated finishing do not have special granulating working procedure and equipment,
Less energy consumption, cost is low;
2, can be according to the needs of crop and soil, the various fertilizer components of regulated at will
Ratio;
3, product particle is a shape, and its flowability is suitable for than good with cylindrical pellet
Mechanized application;
4, the segregation classification problems that does not have different components, constant product quality;
5, positively effect is to promote the industrialization process of organic fertilizer utilization.
6, simple in structure, the high efficiency of production unit.

Embodiment
With a cover water evaporation quantity is 550kg water/h, has the broken dryer of the cylinder of strengthening the granulation function, per hour can produce nitrogen phosphorus potassium total nutrient 15%～20%, organic greater than 20%, water content is less than 0.8 ton of 10% organic composite fertilizer.
