Description
Technical field
The present invention relates to countercurrent drier, particularly a kind of higher, dry Rotatingandflashstreamingdrier of the pasty material of difficult powdering afterwards of solid content that is suitable for.
Background technology
At present, for the continuous drying of the high concentration material such as paste, pasty state, pie, adopt Rotatingandflashstreamingdrier to produce continuously more.The sudden strain of a muscle crushing chamber that revolves that existing Rotatingandflashstreamingdrier is equipped with rotating vane by inside forms, hot blast is blown into revolving sudden strain of a muscle crushing chamber bottom by wind assembling set, dodge the material that crushing chamber dog-house casts be dispersed as powdery by motor-driven rotating vane in by heated-air drying from revolving, the hot blast being risen by rotation is carried secretly to run to and is revolved the air outlet that dodges crushing chamber top, enter the gas-solid separating device that drying system rear portion arranges, isolate granular material product.This Rotatingandflashstreamingdrier can only be used for dry water content relatively low, can be with hot blast rapid draing, and can be rotated blade and all break into the material of powdery.And to some solid content higher and dry after be difficult to be rotated the pasty material (as Cementing agent, the dregs of a decoction etc.) that blade breaks into powdery, be just unsuitable for carrying out continuous drying production with this drying machine.Because this class pasty material, being rotated before blade breaks up, can fall into very soon drying machine bottom under Action of Gravity Field, cause solid accumulation and stop up wind path, make machine down, cannot work.Therefore to this type of pasty material, can only adopt at present baking oven or drying room to carry out discontinuous and be dried, need carry out again fragmentation to forming tabular or block material after dry.This drying mode, the production cycle is long, consumes energy high, after being dried, needs to clear up, and labor strength is high, and operating environment is poor, and production efficiency is low; And material repeatedly loaded and unloaded, easily produce secondary pollution.
Summary of the invention
The problem existing for above-mentioned prior art, the object of this invention is to provide a kind of Rotatingandflashstreamingdrier that dry solid content is higher, be dried the pasty material of rear difficult powdering that is applicable to, to be dried and pulverize on a machine and complete continuously, carry out the broken mode of production in order to replace after dry, dry with baking oven or drying room discontinuous.
For achieving the above object, Rotatingandflashstreamingdrier provided by the invention, comprises frame, wind assembling set, revolves and dodge crushing chamber, rotating vane, motor and belt gear; It is characterized in that: described in revolve and dodge crushing chamber bottom and be back taper; Described rotating vane has multilayer from bottom to top, and wherein the side of undermost rotating vane reclines mutually with base and the inwall that revolves sudden strain of a muscle crushing chamber bottom; Have blanking port revolving to dodge in crushing chamber bottom interior wall, blanking port skeleton is arranged at blanking port bottom, and on blanking port skeleton, cover has filter bag, and the length of filter bag is greater than the twice of blanking port skeleton length; The rotating vane that is positioned at undermost rotating vane top from bottom to top length successively reduces; Between levels rotating vane, have guide disk, the diameter of every layer of guide disk is less than the length of its top rotating vane, and guide disk perimeter has fixing material-blocking ring plate, and the internal diameter of material-blocking ring plate is identical with the length of guide disk top rotating vane; Except ground floor (the superiors) guide disk, on remaining guide disk, there is respectively air vent, the interlaced distribution of air vent of levels guide disk; Motor drives rotating vane and guide disk together to rotate by belt gear and turning cylinder.
When Rotatingandflashstreamingdrier of the present invention is countercurrent drier work, hot blast is entered and revolves sudden strain of a muscle crushing chamber bottom with the annulus high speed of revolving sudden strain of a muscle crushing chamber bottom by wind assembling set after tangentially entering wind assembling set, and rotation is risen; Dodge the material that crushing chamber dog-house casts and first fall on the guide disk of ground floor rotation above by revolving, under the effect of centrifugal force, get rid of to ground floor material-blocking ring plate inwall, material on material-blocking ring plate inwall, under gravity and rotating vane (now rotating vane is equivalent to material scraper plate) effect, is fallen on second layer guide disk by the space between material-blocking ring plate and guide disk; The material dropping on second layer guide disk repeats above-mentioned motion, falls on the 3rd layer of guide disk of bottom; Pass through successively multilayer guide disk so from top to bottom, dodge crushing chamber bottom until fall to revolve.Material constantly contacts with the thermal current rising material-blocking ring plate space with guide disk with the guide disk air vent starting from the second layer in this dropping process, carries out heat convection; Simultaneously, under the effect of multi-layer rotating blade, the material agglomerate being dried is loose gradually, diminishes, and finally falls drying machine bottom and carries out final matter heat exchange, and at this spatial dispersion, dial in shape as the blanking port of trap by the undermost rotating vane rotating, in the time that material runs up to some in blanking port skeleton, the soft filter bag machine internal negative pressure that is dried before this being sucked by gravity backs down, automatically outside discharge machine, become loose dry products.After discharge, filter bag automatic retracted under dryer inner negative pressure (this negative pressure is produced by the air-introduced machine after the gas-solid separating device joining with dryer outlet mouth) effect, in blanking port skeleton, makes blanking port closure, waits for discharge next time.
Compared with prior art, the beneficial effect of Rotatingandflashstreamingdrier of the present invention is:
1, drying machine of the present invention, material needs just to fall to revolve through multilayer guide disk successively to dodge crushing chamber bottom revolving to dodge in crushing chamber from top to bottom, has extended material in walking path and the drying time of revolving in sudden strain of a muscle crushing chamber, makes dry materials more abundant.
2, enter rotation thermal current in drying machine and disperse to rise by the space between air vent and guide disk and material-blocking ring plate interlaced on upper and lower guide disk, make it more abundant with the contacting of material, matter heat exchange, heat utilization rate is high.
3, drying machine of the present invention adopts lower marker method, utilizes the blanking port skeleton arranging on the blanking port of bottom and be socketed in filter bag on skeleton the interruption automatic discharge of having realized drying machine.
4, drying machine of the present invention completes dry and pulverizing higher solid content, pasty material that be dried rear difficult powdering on a machine simultaneously, and than being dried, carrying out with baking oven or the advanced row discontinuous of drying room, broken drying mode is with short production cycle, efficiency is high; Energy consumption is low; And can not make material be subject to secondary pollution.
