Hollow outer shaft 19 is placed in the outside of interior rotating shaft 23, and stretch out outside hollow outer shaft 19 end of interior rotating shaft 23;
Hollow outer shaft 19 and interior rotating shaft 23 are arranged on support 4 by bearing respectively.
Air intake cylinder 5 is provided with air inlet 17; The bottom of air intake cylinder 5 is provided with mud hole 18.
In the interior rotating shaft 23 of described blade 8 belows, be provided with and prevent that material from entering the material leak-proof end cap 14 in hollow outer shaft 19.
This flash dryer working mechanism is as follows:
Hot blast enters from air inlet 17, after air intake cylinder 5, enters sieve section cylinder 7 from bottom.The similar 90 ° of elbows of structure of air intake cylinder 5, can effectively reduce drag losses.When hot air flow is during through porous sieve plate 6, because flow area becomes suddenly aperture, hot blast speed increases rapidly, this kind of structure can ensure that the air-flow that flows into sieve section cylinder 7 produces larger speed, be enough to the bulk materials of fully not breaing up that falls to sieve section cylinder 7 bottoms to blow afloat, again enter and break up region, by bottom scraper blade more than 16 time to bulk materials fragmentation.
Compared with the reverse taper formula structure of traditional flash drying equipment, sieve section barrel structure can produce radially equally distributed straight air stream instead of traditional swirling eddy, takes full advantage of dry place, has shortened circulation path, effectively reduced drag losses, energy-saving effect is remarkable.Filter cake shape or plaster pasty materials drop to the blade 8 and breaing up in region that lower blade 15 forms of High Rotation Speed through feeding screw 13, because blade lean is installed, the material clashing into through blade 8 oliquely downward moves, between the material of high-speed motion and the lower blade of reverse rotation 15, produce very large relative velocity, lower blade acutely clashes into material, due to the identical but direction of rotation difference of upper and lower two-layer blade lean direction, the material being clashed into by lower blade 15 counter motion at once, bump with blade 8 again, material is thoroughly broken up in reciprocating process.
Under same rotating speed, this flash dryer transmission mechanism can make that upper and lower blade is positive and negative to be relatively rotated, there is the larger speed of relatively breaing up than traditional dispersing device, produce the larger active force of breaing up, wet stock particle becomes more tiny through breaing up, thereby shorten drying time, effectively saved the dry energy.
A small amount of lump material of fully not breaing up, fall under gravity into sieve section cylinder 7 bottoms, and then blown afloat rapidly by the high velocity air through porous sieve plate 6 again, the bottom scraper blade 16 of High Rotation Speed is repeatedly broken up fragmentation to material, fine particle after fragmentation moves upward with hot blast, complete rapidly dry run, also make passage (drying 9 or sieve section cylinder 7) obtain cleaning, reduced the possibility of solid accumulation simultaneously.Even if remaining a small amount of material residue also can be discharged by mud hole 18.
In arid region (drying 9), fully contact with the equally distributed hot blast of velocity field through fully breaing up the material particles that becomes more tiny, realize and conducting heat and mass transport process fast, compared with traditional flashing apparatus, obviously shorten drying time of the present invention.A large amount of materials are with hot blast fast rise, through the screening effect of screen pack 12, meet dry requirement and particle diameter and pass through screen pack 12 lower than the material of screening particle diameter, discharge through discharging opening 11, realize the collection of dried material through separators such as follow-up sack cleaners, large granular materials in dry cylindrical shell is kept off back dry cylindrical shell, proceeds broken and dry.
As mentioned above, just can realize preferably the utility model.
Embodiment of the present utility model is not restricted to the described embodiments; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
