During work, after starter motor, motor via reducer drives the spill support roller (main support roller) be attached thereto to rotate, and drying machine is rotated at least four support rollers, graininess wet stock joins hothouse from hopper, falls in hothouse along the guiding flight tilted at hothouse charging aperture.Hot blast to be transported in air inlet main pipe by blower fan and to be discharged by jet nozzle, and directly winding-up is on material.After material is heated, moisture evaporates and progressively drying, and the gas produced after moisture evaporation and tail gas move axially, and discharge from the exhaust outlet of expansion chamber.By the air pressure in air blast and air-introduced machine balance hothouse.
Material moves from the gap of charging aperture by helical arc plate to expansion chamber direction under the effect of helical arc plate and air-flow, when granular material enters grading room by special-shaped flight, first fine powder and qualified particle fall on outer screen drum by interior screen drum, after the rotation of grading room makes qualified particle be separated with fine powder, qualified product is discharged from products export, and the sieve aperture that qualified product granularity is greater than outer screen drum is less than the sieve aperture of interior screen drum simultaneously.
Fine powder is discharged from fine powder outlet.After not entering crushing chamber by the bulky grain of interior screen drum from interior screen drum, broken
Be squeezed in the gap of broken room screen drum and crushing cutter and be broken, the material be broken falls into outer screen drum by crushing chamber screen drum and also discharges from products export and fine powder outlet respectively after classification.Drying, classification, a broken machine complete, and system is continuous operation.Dryer entrance temperature is 60-300 DEG C, and material water ratio (wet basis) is no more than 25%.The inclination angle of helical arc plate, central angle, hothouse rotating speed and wind speed are the major measure controlling residence time of material, and this is known technology, therefore not repeated description.
First, second reinforcement plays outside supporting, the effect of interior screen drum, also plays the effect pushing material to fine powder outlet and products export in grading room rotary course simultaneously.
Broken tool arm is Collapsible structure, and can regulate the gap of crushing cutter and crushing chamber screen drum, broken tool arm can freely swing in radial directions.Fall on outer screen drum through crushing chamber screen drum after large granular materials is broken, more classified rear discharge.
Grading room, crushing chamber and hothouse synchronous rotary.In the side of expansion chamber, manhole and visor are installed, the equipment of grading room and crushing chamber can be overhauled.
Each described screen drum, according to the shape of granule materials and the size of granularity, selects slot size and shape.Such as material can be cylindrical or spherical etc., and interior screen drum and outer screen drum are braiding steel mesh, and crushing chamber screen drum is the metal lath of punching.The needs of inclination angle depending on material of described many groups helical arc plate and the humidity of material, this is known technology.
Its advantage is:
The present invention can complete the continuous drying of graininess wet stock, classification and fragmentation procedure, and by changing wind speed and rotating speed, product moisture content can freely control, and improves production efficiency, also reduces energy consumption.Compact equipment, multi-functional machine, shortens production procedure.Floor space is little, saves manpower, reduces the labour intensity of workman.Decrease loss of material, reduce environmental pollution, also prevent the pollution of reporting to the leadship after accomplishing a task of material.Equipment operating is simple, and the indexs such as residence time of material, baking temperature, Cut size can meet the needs of different material by changing operating condition.The rolling of particle in hothouse and rubbing, have polishing action to particle, eliminates and be attached to fine powder on particle and corner angle, make product surface smooth, no longer produce fine powder.Equipment mechanical dead angle, easy to clean, is convenient to change kind.Be specially adapted to the drying after the material granulation such as agricultural chemicals, medicine, feed, Chinese medicine, electuary.
