Abstract

The invention relates to a drying device for porous fragile granular products, and belongs to the technical field of drying equipment. The drying device for the porous fragile granular products includes the public prior art, and is further characterized by comprising two air inlets. Hot air is divided into two branches after being discharged through a hot air outlet (5-3) of a steam radiator, the first branch of the hot air enters a dryer through the axial air inlet (6), and the second branch of the hot air enters the dryer through the tangential air inlet (7). The drying device for the porous fragile granular products has the advantages that due to the fact that drying is carried out through slow axial rotation of primary hot air and slow tangential rotation of secondary hot air, the products are low in moisture, the number of porous fragile grains is small, and the drying device for the porous fragile granular products is quite applicable to products needing to keep the complete crystal shape.

Description

The drying equipment of a kind of porous, friable particle shape product
Technical field
The present invention relates to a kind of drying equipment, especially a kind of drying equipment that is applicable to porous, friable particle shape product, belongs to drying equipment technical field.
Background technology
In food medicine and new material industry, often to use drying equipment, the most generally with commonly pneumatic drier, Rotatingandflashstreamingdrier and Vibratingfluidbeddrier.These drying machines are more convenient suitable in dry common material, but for some porous, friable particle shape product, dry in these drying machines is to be but very easy to fragmentation.Because hot blast axial flow velocity 20-40 meter per seconds in common pneumatic drier pipe, wind speed is too fast too quickly, so being dried for porous, friable particle shape product, be easy to make product broken, if but reduce axial flow velocity, can make again the productivity ratio of product decline, so be inapplicable; Common Rotatingandflashstreamingdrier is a kind of drier of applicable high humidity high viscosity wet feed, although its axial flow velocity is 2-6 meter per seconds, but there is lower stirring (speed is generally at 100 to 1000 revs/min), and the tangential gas flow speed that hot blast speed enters drying machine is up to 30-60 meter per seconds, easily cause the fragmentation of porous, friable particle shape product, can not keep the complete of crystal shape, therefore common Rotatingandflashstreamingdrier is also unsuitable for the dry of porous, friable particle shape product; And for Vibratingfluidbeddrier, because the time of staying is short, the moisture in porous, friable particle shape product fully can not be removed; Fixed bed-fluidized bed drying machine, because the classification of particle, a large amount of fine powders is entrained into as " byproduct ", can cause the yield of finished product to reduce, therefore common fluid bed dryer is not suitable for the dry of porous, friable particle shape product equally.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of drying equipment that is applicable to porous, friable particle shape product, can not cause the Particle Breakage of porous, friable particle shape product, can adapt to the product of " needs keep perfect crystal shape ".
To achieve these goals, the technical solution used in the present invention is: the drying equipment of a kind of porous, friable particle shape product, comprise airduct, filter, blower fan, gas heater, feeder, hopper, pneumatic conveying drying chamber, dry materials chamber, recuperator and discharge pipe, pneumatic conveying drying chamber, dry materials chamber, recuperator connect from down to up successively; Described airduct is sent hot blast into pneumatic conveying drying chamber by filter, blower fan, gas heater successively; Feeder is placed in the sidewall below of dry materials chamber, and hopper is connected on feeder; Discharge pipe is placed on the sidewall of recuperator; This drying equipment also has a steam radiator being connected with gas heater, which is provided with hot blast import, steam-condensation water outlet and hot-blast outlet; The cylinder side wall of described pneumatic conveying drying chamber is provided with a tangent air inlet, and bottom is also provided with an air inlet through hollow shaft mouth, and two air inlets on pneumatic conveying drying chamber are connected by airduct with the hot-blast outlet on steam radiator respectively.
Between described dry materials chamber and recuperator, also connect one and expand impulse drying chamber.
The outside of dry materials chamber and expansion impulse drying chamber is overlapped respectively and is had heating jacket, and the outside of described heating jacket is also provided with hot water inlet and hot water outlet, and hot water outlet is placed on hot water inlet; Described drying equipment also comprises a steam-condensation water collecting tank, and condensation water collection tank hot water inlet is connected with the steam-condensation water outlet on steam radiator, and condensation water collection tank hot water outlet is connected with the hot water inlet on heating jacket.
Described feeder is electric and magnetic oscillation feeder.
The present invention compares with in the past traditional drying equipment, progress is that the pneumatic conveying drying chamber of drier comprises two air inlets, after hot blast is discharged by the hot-blast outlet of steam radiator, be divided into two, first hot blast enters pneumatic conveying drying chamber by air inlet through hollow shaft mouth, and second hot blast enters pneumatic conveying drying chamber by tangent air inlet; The hot blast of tangential rotation makes material slow circumvolve in the tube wall of drying machine, hot blast axial flow velocity 5-10 meter per seconds, and hot-air flow speed 8-15 meter per seconds of tangential rotation, have extended residence time of material on the one hand, on the other hand also steam saving; Owing to having used being dried of hot blast two strands of thermal currents axial and the tangentially secondary hot-air of rotation slowly, so product moisture is low and porous particle is frangible few, be highly suitable for the product of " need to keep perfect crystal shape ".
Charger of the present invention, by traditional helical feed, changes electric and magnetic oscillation reinforced, can not cause the Particle Breakage of porous, friable particle shape product.
The present invention also has a steam-condensation water collecting tank, drier outer cover has heating jacket, the steam condensate (SC) of discharging in steam radiator can reach 70-90 degrees Celsius, by hot water inlet, pass in heating jacket, be a kind of heat transfer type of indirect, can guarantee the dry of material, the heat of steam condensate (SC) has recovery simultaneously, save steam expense, met low-carbon (LC) and environmental requirement.
