Description
Technical field
The present invention relates to a kind of drying plant, more particularly to a kind of direct heating stoving machine.
Background technology
Dryer: i.e. drying equipment or drying machine, thermal source have coal, electricity, gas etc.；Drying mode point：Hot airflow type and radiation
Formula etc., thermal current drying: is provided with charging aperture, drying is stopped up ［ inside setting broken ］, once gathered dust with secondary cyclone ［ discharging opening ］, hot blast
Stove, air blast, induced-draught fan, Transfer pipe, go out wet mouth.
Thermal vapor stream dryer, its operation principle：By independent hot-blast stove heat production, the connection of Jing connectors, turned by air blast at a high speed
Movable property gives birth to wind-force, and the thermal current for producing combustion chamber of hot-blast stove of drying blows to another tail end from the communicated passage in one end, and heat is directly
Material is passed to, material is blowed to cylinder drying room by charging aperture broken, the heated rear wet steam of pulverized particulate dust
Evaporation departs from, and volume lightens, and is blown afloat suspension by steam flow and rises, and when mass dryness fraction is inadequate, the dust for being blown afloat is under gravity by upper
Down fall, inside set device and rotate at a high speed, stir scattered dust and blown afloat by steam flow and rise top again compared with dry dust, wet steam is with more dry
Dust together rises towards tail end flowing, and dust is constantly heated at the volley, and moisture content is constantly in evaporation, Jing first time cyclone dust collections
During room, material declines, and rotation produces suction to induced-draught fan at a high speed, and partial material and steam flow continue to be drawn to afterbody, are revolved in Jing for the second time
During wind dust chamber, material is harvested substantially, and material Jing gathers dust more than twice and obtains product, and in moisture, entrainment of fine dust is by air draught
To tail end, wet steam is discharged to sky to band, so far completes entirely to dry flow process, contains more harmful components in wet steam, due to broken dress
Put and product become into powdering, crystal no longer, quality decline, material is too thin, gather dust it is difficult to the greatest extent, also because wind speed makes band moisture content thing easily occur
Attached wall, makes volume reducing, therefore various industries does not use similar furnace drying method.
Separately there is the China Patent No. to be：201320715941.4, the day for announcing is a kind of energy-efficient sticky materials of 2014.4.16
The utility model of dryer, which includes drying frame, is connected with Drying, crushing power is rotatably connected in Drying in frame
Device, drives dryer main shaft, the lower front of Drying to be provided with charging aperture, lower rear and be provided with discharging opening, dries main shaft
On leading portion equipped with breaker, spiral stirring device is housed on back segment, the upper front end of the Drying equipped with hot blast access tube,
Upper rear end is equipped with hot wind discharge duct.Clay-bonded sand group can be carried out effectively crushing and loose by the utility model, so as to be prevented effectively from
There is clay-bonded sand clustering phenomena and the water content in energy effective control clay-bonded sand.Its hot blast is passed directly in Drying, after causing
Continuous substantial amounts of dust, waste gas discharge, as product is become powdering by breaker, crystal no longer, quality decline, more special thing
Material drying is in use, therefore various industries do not use similar furnace drying method.
Fluidizing type thermal vapor stream dryer or fluid bed：Independent hot air furnace heat exchange system is provided with, (Some Enterprises use steam
Heat exchanger) including high power air blowers, induced-draught fan, spiral feeding motor, high-power vibration motor, thermal current transfer canal system
System, moisture absorption cover lid, damp and hot gas pipeline, hydrofuge chimney, charging aperture, thermal vapor stream envelope, inner support reinforced liner, separated material orifice plate,
Go out material screen, discharging opening, cyclone dust collection room, secondary cyclone dust chamber, its operation principle：After heat energy is obtained, air blast is logical by heat
Superheat flow transfer canal system, by each transmission arm, blows out thermal current from lower to upper from separated material orifice plate, and heat is directly passed to thing
Material, gas blow on separated material orifice plate it is material bed on material suspended, and the constantly material of heated material layer, by vibrating motor not
Disconnected shake, forms to expect that pusher method squeezes away material during shake.
The damp and hot steam flow being constantly evaporated in dry run needs quickly to drain, and induced-draught fan runs up generation suction
Damp and hot steam flow is quickly siphoned away by power, air draught by force, carries more fine crystals or dust in steam flow secretly, Jing first during siphoning away
During secondary cyclone dust collection room, fine crystals or dust fall, and wet steam stream continues motion, is received during second cyclone dust collection room of Jing substantially
To the greatest extent, moisture is taken away in air draught, suctions out wet steam and arranges heavenwards by chimney, can both pack warehouse-in after the placed cooling of drying product,
So far complete entirely to dry flow process, be the drying plant used by most of manufacturing enterprise.
Fluidizing type thermal vapor stream dryer or fluid bed, which exists following not enough：First, need to be independent heat-exchanger rig, system is huge
Big floor space is more, and heat energy thermal losses in transmitting procedure is larger, two, yield it is less, material thickness super only 2 when flowing water is moved
Millimeter, three, limit production capacity, to expect that pusher can cause material moisture content residual many when adding slightly many, do not reach drying effect；
4th, material is selected, because being percolation gas, when material is too thin, can be siphoned away by air draught in a large number, gather dust more thin more receive endless, not
Dare to use, five, dried material need to cool down 2-4 hours, otherwise product is hardened, and consumer is difficult with, and discharging opening can not
Directly pack；6th, a small amount of dust is had during cold scattering and gas is distributed in the air；Seven Dian wet steam stream air draft system very complicateds are too huge,
Eight, exhaust outlet a large amount of gases have more dust to be carried over arranging heavenwards when blowing out, the composition being carried in moisture have chlorine, phosphorus, ammonium,
Harmful gas such as arsenic, nitrogen causes secondary pollution, nine, drying place include fuselage, roof, have dust everywhere, ten, main defect,
Own wt is all pressed on vibrations spring, material fatigue is easily occurred using rear for a long time, is only shaken, and does not walk material, and 11, long
After time use, organism run-off the straight, disequilibrium, tear fuselage phenomenon, 12, installed capacity is big, power consumption cost is high, ten
3rd, thermal source is using single.
