Description
Technical Field
The invention relates to the technical field of material sorting, in particular to wet soft viscous particle material sorting equipment.
Background
The existing granular materials such as granular compound fertilizer, granular organic fertilizer, metallurgical pellets, ceramic ceramsite and the like are distributed in various industries, and the preparation of the granular materials still adopts the traditional granulating process flow, namely, batching, stirring, granulating, drying, cooling, grading, returning to granulating/coating and packaging.
Taking a granular compound fertilizer as an example, the specific production process is as follows:
1. raw material proportioning: preparing raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, common calcium), potassium chloride (potassium sulfate) and the like according to a certain proportion (according to market requirements and soil detection results in various places);
2. stirring raw materials: uniformly stirring the prepared raw materials, and improving the uniform fertilizer efficiency content of the whole fertilizer particles;
3. granulating raw materials: feeding the uniformly stirred raw materials into a granulator, and granulating by utilizing steam and an adhesive (a rotary drum granulator or a disc granulator can be used as an option);
4. and (3) drying particles: the granules manufactured by the granulator are sent into a dryer, and moisture contained in the granules is dried, so that the strength of the granules is increased, and the granules are convenient to store;
5. and (3) cooling particles: the temperature of the dried fertilizer particles is too high, the fertilizer particles are easy to agglomerate, and the fertilizer particles are convenient to bag, store and transport after being cooled;
6. and (3) grading particles: classifying the cooled particles, crushing and re-granulating the particles with unqualified particle sizes and granules, and screening out qualified fertilizer particles;
7. and (3) coating a finished product: coating and enveloping the qualified fertilizer particles, and increasing the brightness and roundness of the particles;
8. and (3) packaging a finished product: and (5) bagging the particles (namely the finished product) coated with the film, and storing the particles in a ventilation place.
In the process, the granulated spherical granular materials are wet, soft and high in viscosity, all the spherical granular materials are put into a dryer for drying, and then enter a cooler for cooling and hardening after being dried, and then grading screening of qualified particle sizes is carried out, but the finished product qualification rate of the granular materials sorted out by the existing process is low (only accounts for about 20% of the total material quantity, for example, the finished product with the qualified particle size of 10t/h is produced, the system load of 50t/h is needed), and the super-particle size particles (crushed) and the small-particle size seed crystal particles and powder screened by the grading process are returned to the granulator and are wetted again for granulation. The whole production system repeatedly dries and wets again, wets and dries again, causes a large amount of loss of raw materials and power consumption of system equipment, and makes the manufacturing cost of product high.
Therefore, the granulated granular materials are directly sorted, so that the material yield of the granular materials entering the drying equipment is improved, and the energy saving and consumption reduction can be realized under the condition that the maximum drying and production capacity of a drying and subsequent system in a granular production line are kept unchanged.
However, the state of the granular materials from the granulator is complex, the granular materials have large moisture, high viscosity, low hardness, even different fineness of the particle size, impurities and the like, the granular materials are high-temperature of 60-70 ℃, even the neutralization reaction of strong acid and alkali and phenomena of rapid hardening, hardening and hardening are also included, the sorting operation surface of the equipment is adhered and blocked in a large area during sorting operation, even the surface of the equipment is rapidly hardened, mechanical locking of the equipment is caused, and meanwhile, the roundness and compactness of the sorted formed granular materials are insufficient.
In view of the above, the invention provides wet soft viscous granular material sorting equipment, which can sort wet soft viscous materials after granulation, break the cohesive force among the granular materials, solve the problems of rapid hardening and hardening of the granules, avoid equipment adhesion in the sorting process, screen the granules with the proper grain size, send the granules to a dryer for drying, send unqualified materials to a granulator for secondary granulation, improve the qualification rate of finished products, save energy and reduce consumption.
