Description

A kind of New type direct-heating dryer

Technical field

The utility model relates to a kind of drying plant, particularly relates to a kind of New type direct-heating dryer.

Background technology

Dryer: i.e. drying equipment or drying machine, thermal source has coal, electricity, gas etc.; Drying mode divides: hot airflow type and radiant type etc., and thermal current is dried: be provided with charging aperture, drying is stopped up ［ inside establishing fragmentation ］, once gathers dust with secondary cyclone ［ discharging opening ］, hot-blast stove, air blast, induced-draught fan, Transfer pipe, goes out wet mouth.

Thermal vapor stream dryer, its operation principle: by independent hot-blast stove heat production, connect through connector, wind-force is produced by air blast high-speed rotation, the thermal current that combustion chamber of hot-blast stove produces is blowed to another tail end from one end through Transfer pipe by blowing, heat is directly passed to material, material is blowed to cylinder drying indoor broken by charging aperture, the wet steam evaporation after heating of pulverized particulate dust departs from, volume lightens, blown afloat to suspend by steam flow and rise, when mass dryness fraction is inadequate, fallen from top to bottom under gravity by the dust blown afloat, inside establish device High Rotation Speed, stir loose dust to be blown afloat comparatively dry dust by steam flow and again to rise top, wet steam together rises towards tail end with comparatively dry dust and flows, dust is constantly heated at the volley, moisture content is constantly in evaporation, when first time cyclone dust collection room, material declines, induced-draught fan High Rotation Speed produces suction, partial material and steam flow are continued to inhale rearwardly, when through second time cyclone dust collection room, material is harvested substantially, material gathers dust through more than twice and obtains product, in moisture entrainment of fine dust by induced-draught belt to tail end, wet steam is discharged to sky, so far whole oven dry flow process is completed, containing more harmful components in wet steam, because product is become powdery by breaker, crystal no longer, quality declines, material is too thin, gather dust to the greatest extent difficult, also because wind speed makes band moisture content thing easily occur attached wall, make volume reducing, therefore multiple industry does not use similar furnace drying method.

China Patent No. is separately had to be: 201320715941.4, the day for announcing is the utility model of the energy-efficient sticky material dryer of 2014.4.16 mono-kind, it comprises oven dry frame, frame is connected with Drying, crushing power device is rotatably connected in Drying, drive dryer main shaft, the lower front of Drying is provided with charging aperture, lower rear is provided with discharging opening, the leading portion of oven dry main shaft is equipped with on breaker, back segment spiral stirring device is housed, the upper front end of described Drying is equipped with hot blast access tube, upper rear end is equipped with hot wind discharge duct.Clay-bonded sand group can carry out effectively broken and loose by the utility model, thus effectively avoids occurring clay-bonded sand clustering phenomena and effectively can control the water content in clay-bonded sand.Its hot blast directly passes in Drying, causes follow-up a large amount of dust, toxic emission, and because product is become powdery by breaker, no longer, quality declines crystal, and more special drying materials is in use, and therefore multiple industry does not use similar furnace drying method.

Fluidizing type thermal vapor stream dryer or fluid bed: be provided with independent hot air furnace heat exchange system, (Some Enterprises use vapor heat exchanger) comprises high power air blowers, induced-draught fan, spiral material loading motor, high-power vibration motor, thermal current transfer canal system, moisture absorption cover cap, 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 acquisition heat energy, heat is passed through hot-fluid transfer canal system by air blast, by each transmission arm, thermal current is blown out from lower to upper from separated material orifice plate, heat is directly passed to material, material suspended on to blow on separated material orifice plate material bed of gas, and the material of continuous heated material layer, constantly shaken by vibrating motor, formed to expect that pusher method squeezes away material during shake.

The damp and hot steam flow be constantly evaporated in dry run needs to drain fast, induced-draught fan runs up generation suction, damp and hot steam flow siphons away by air draught by force fast, more fine crystals or dust is carried secretly in steam flow, when siphoning away in process through first time cyclone dust collection room, fine crystals or dust fall, wet steam stream continues motion, substantially receive to the greatest extent when second time cyclone dust collection room, moisture is taken away in air draught, sucking-off wet steam by chimney discharged to sky, dry product and both can pack warehouse-in after placing cooling, so far whole oven dry flow process is completed, it is the drying plant that most of manufacturing enterprise uses.

Fluidizing type thermal vapor stream dryer or fluid bed, it exists following not enough: one, need be independent heat-exchanger rig, the huge floor space of system is many, heat energy thermal losses in transmitting procedure is larger, two, output is less, super only 2 millimeters of material thickness during flowing water motion, and three, limit production capacity, material moisture content can be caused during to expect that pusher adds slightly many residual many, do not reach drying effect, four, material is selected, because be percolation gas, when material is too thin, can be siphoned away in a large number by air draught, gather dust and more carefully more receive endless, dare not use at all, five, dried material needs cooling 2-4 hour, otherwise product hardens, consumer is difficult to use, and discharging opening can not directly pack, six, a small amount of dust is had during cold scattering and gas distributes in the air, seven Dian wet steam stream air draft system very complicateds are too huge, eight, more dust is had to be taken out of discharged to sky during the blowout of exhaust outlet a large amount of gas, chlorine is had by the composition taken out of in moisture, phosphorus, ammonium, arsenic, harmful gas such as nitrogen causes secondary pollution, nine, dry place and comprise fuselage, roof, there is dust everywhere, ten, main defect, own wt is all pressed on vibrations spring, long-time use easily occurs that material is tired afterwards, only vibrations, do not walk material, 11, after long-time use, organism run-off the straight, disequilibrium, tear fuselage phenomenon, 12, installed capacity is large, power consumption cost is high, 13, thermal source uses single.
