Description
Technical field
The present invention relates to countercurrent drier, particularly a kind of Rotatingandflashstreamingdrier that is suitable for the pasty material of the difficult powdering in higher, the dry back of solid content.
Background technology
At present, the continuous drying for high concentration material such as paste, pasty state, pies adopts 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 constitutes; Hot blast is blown into to revolving sudden strain of a muscle crushing chamber bottom by wind assembling set; Dodge the material that the crushing chamber dog-house casts and in by heated-air drying, be dispersed as powdery from revolving by motor-driven rotating vane; The hot blast that is risen by rotation is carried secretly to run to and is revolved the air outlet that dodges crushing chamber top, gets into the gas-solid separating device that the drying system rear portion is provided with, and isolates the 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 the material that blade all breaks into powdery.And some solid content is difficult to be rotated the pasty material (like oil well cementation agent, the dregs of a decoction etc.) that blade breaks into powdery after the higher and drying, just be inappropriate for this drying machine and carry out continuous drying production.Because this slurry material can fall into the drying machine bottom very soon being rotated before blade breaks up under the gravity effect, cause solid accumulation and stop up wind path, make machine down, can't work.So to this type of pasty material, can only adopt baking oven or drying room to carry out the discontinuous drying at present, need carry out fragmentation again to forming tabular or block material after the drying.This drying mode, the production cycle is long, and power consumption is high, need clear up after the drying, and labor strength is high, and operating environment is poor, and production efficiency is low; And material is by repeatedly loading and unloading, easy generation of secondary pollution.
Summary of the invention
Problem to above-mentioned prior art existence; The purpose of this invention is to provide a kind of Rotatingandflashstreamingdrier that is applicable to the pasty material of the difficult powdering in higher, the dry back of dry solid content; Drying is accomplished with pulverizing on a machine continuously, carried out the broken mode of production after, the drying dry with baking oven or drying room discontinuous in order to replace.
Be to realize above-mentioned purpose, 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: the said sudden strain of a muscle crushing chamber bottom of revolving is back taper; Said rotating vane has multilayer from bottom to top, and wherein the side of end rotating vane reclines with the inwall that revolves sudden strain of a muscle crushing chamber bottom with the base mutually; Blanking port is arranged revolving to dodge on the crushing chamber bottom interior wall, the blanking port skeleton is arranged at the blanking port bottom, is with filter bag on the blanking port skeleton, and the length of filter bag is greater than the twice of blanking port skeleton length; The rotating vane that is positioned at rotating vane top, end length from bottom to top successively reduces; The guide disk is arranged between the levels rotating vane, and the diameter of every layer of guide disk is less than the length of its top rotating vane, and the 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 that ground floor (the superiors) guide disk, on remaining guide disk air vent is arranged respectively, the interlaced distribution of air vent of levels guide disk; Motor together rotates through belt gear and turning cylinder driven in rotation blade and guide disk.
When Rotatingandflashstreamingdrier of the present invention was countercurrent drier work, hot blast revolved sudden strain of a muscle crushing chamber bottom, rotation rising by wind assembling set with the annulus high speed entering of revolving sudden strain of a muscle crushing chamber bottom after tangentially getting into wind assembling set; Dodge the material that the crushing chamber dog-house casts and fall earlier on the guide disk of top ground floor rotation by revolving; Under action of centrifugal force, get rid of to ground floor material-blocking ring plate inwall; Material on the material-blocking ring plate inwall is fallen on the second layer guide disk by the space between material-blocking ring plate and the guide disk under gravity and rotating vane (this moment, rotating vane was equivalent to the material scraper plate) effect; The material that drops on the second layer guide disk repeats above-mentioned motion, falls on the 3rd layer of guide disk of bottom; Pass through multilayer guide disk so from top to bottom successively, dodge the crushing chamber bottom until falling to revolve.Material in this dropping process constantly with the guide disk air vent that begins from the second layer and guide disk and material-blocking ring plate space the thermal current that rises contact, carry out heat convection; Simultaneously, under the effect of multilayer rotating vane, the material agglomerate that is dried is loose gradually; Diminish, fall the drying machine bottom at last and carry out final matter heat exchange, and in this space disperse; Dial in the blanking port of shape such as trap by the end rotating vane that rotates, when material ran up to some in the blanking port skeleton, soft filter bag that the machine internal negative pressure sucks backed down to lean on gravity to be dried before this; Automatically outside the discharge machine, become loose dry products.Behind the discharge, filter bag retracts in the blanking port skeleton down in dryer inner negative pressure (this negative pressure is produced by the air-introduced machine of the gas-solid separating device back that joins with the dryer outlet mouth) effect automatically, makes the 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 need in the crushing chamber just fall to revolve through multilayer guide disk successively to dodge the crushing chamber bottom revolving to dodge from top to bottom, have prolonged material revolving the walking path and the drying time of dodging in the crushing chamber, make dry materials more abundant.
2, the rotation thermal current that gets in the drying machine disperses to rise through interlaced air vent and the space between guide disk and material-blocking ring plate on the guide disk up and down, makes it more abundant with the contacting of material, matter heat exchange, heat energy utilization rate height.
3, drying machine of the present invention adopts marker method down, utilizes the blanking port skeleton that is provided with on the blanking port of bottom and is socketed in filter bag on the skeleton and has realized the automatic discharge that is interrupted of drying machine.
4, the pasty material of the difficult powdering in solid content is higher, the dry back of drying machine of the present invention dry and pulverize on a machine and accomplish simultaneously, than dry with baking oven or the advanced row of drying room discontinuous, carry out that broken drying mode is with short production cycle, efficient is high again; Energy consumption is low; And can not make material receive secondary pollution.
