Description
Technical field
The utility model relates to a kind of columnar structured continuous schedule sintering machines, belong to metallurgy industry sinter production technology neck
Domain.
Background technique
Sinter production needs continuous mainly by step-by-step movement and continuous pallettype sintering machine in art production process in metallurgy industry
Cloth mixture after cloth grate-layer material is carried out to the empty station vehicle of sintering machine head cycle operation, be each covered with mixture trolley be both needed to through
Cross ignition furnace to mixing charge level light after, using trolley downdraft be sintered cycle operation process.With widely applied
For continuous pallettype sintering machine, sintering machine mainly by rack, transmission device, tail portion regulating device, trolley, head and tail portion sealing plate,
Ground way, bellows and air intake device of flue composition etc.；In the top on sintering machine head, shop fixtures feed bin and grate-layer material cloth dress
It sets, blending bunker and mixture distributor device, ignition furnace are arranged successively；It is sintering platform between head seal plate and tail portion sealing plate
Face, being sintered is bellows on the downside of table top, and bellows two sides are ground way, forms mobile sealing with mobile trolley；On the downside of bellows
It is connect with flue, the operation of blower exhausting, is in negative pressure state on bellows and sintering table top, the trolley on sintering machine is in drive system
Circular flow in orbit under driving；The empty station vehicle on sintering machine head passes through grate-layer material distribution device, In when passing through shop fixtures feed bin
It is 10~25mm that trolley upper wall portion, which spreads one layer of granularity, with a thickness of 20~40mm fritter finished product sinter as grate-layer material；Through
By mixture, along trolley, direction is uniformly distributed mixture distributor device in length and breadth when crossing blending bunker, forms epigranular, surface is put down
The mixing bed of material that is whole and having certain laxity；Cloth, which finishes, to be loaded with the trolley of mixture and enters ignition furnace through head sealing plate,
It is in negative pressure state that charge level is mixed under the action of exhaust fan, and 1200 degree or so burnt in ignition furnace of flame is pumped into mixture
Mixture top is lighted in face, and trolley successively moves ahead under the action of driving device, and the mixture being ignited carries out from top to bottom
Successively there is sintering ore bed, burning zone, preliminary heating zone, drying layer and excessive moistening layer in sintering process, in the process of trolley Forward sintering
In, excessive moistening layer, drying layer, preliminary heating zone, burning zone die off, finally only remaining sintering ore bed, are referred to as sinter cake, sinter cake
The red ore bed of high temperature account for about the 1/3-1/4 of sinter cake height；Sintering process finishes, and sinter cake leaves tail with trolley and seals, and arrives
Up to sintering machine tail portion through U-rail downlink, sinter cake leaves trolley and falls into crusher, the empty station after discharging under the effect of gravity
Vehicle returns to the head cyclic process again of sintering machine；Sinter cake enters cooler after crushing and is cooled down, and has cooled down
Complete sinter is delivered to screening plant and is sieved, and granularity is less than the return burden process of 5mm, and granularity is the work of 5mm or more
It is used for finished product sinter for blast furnace process, the finished product sinter that part of granularity is 10-25mm is delivered to shop fixtures feed bin work
For grate-layer material cycle sintering technical process.
In art production process, first is that being both needed to one layer of granularity of paving before the empty station Che Bu mixture of each cycle operation
10-25mm, thickness 20-40mm finished product sinter as grate-layer material, part finished product mine as grate-layer material cycle sintering, in conveying and
The part energy is consumed during shop fixtures cycle sintering；Second is that sintering cyclic process in each empty station vehicle after being covered with mixture,
It is both needed to light by surface 10-20mm depth of the ignition furnace to mixture, ignition media, ton mine blast furnace is done with blast furnace gas
Gas consumption is at 30-50 meters cubes or so, and every cubic metre of blast furnace gas is with the calculating of 0.11-0.13 member, and economic value is in 3.3-6.5
Between member, i.e., sintering ignition process need to consume a large amount of energy；Third is that during the circular flow of equipment, trolley ontology and bullet
Property sealing surface, ground way sealing surface, head and tail seal face abrasion cause system air leakage, with ageing equipment deformation, abrasion
The intensification of degree, air leak rate of air curtain are gradually increased, the synthesis air leak rate of air curtain of sintering machine in 20%-50% or so, main exhauster effective wind rate
Utilization rate reduces, and the invalid air quantity leak into increases the flow and flow velocity of exhaust gas, influences dedusting, desulfurization and out of stock load；Four
It is the proportionate relationship of thickness of feed layer and air leak rate of air curtain, the thickness for increasing sinter bed will cause system air leakage more serious, limit
The cloth height of mixture, bed of material accumulation of heat effect cannot get sustainable utilization；Fifth is that sintering machine head end is to sintering machine tail in production process
The sintering operating condition in portion is inconsistent, ignition furnace lower bellows valve opening bottom, keeps lower negative pressure igniting, exhaust gas flow is small, temperature is low；It is high
SO2、NOXExhaust gas concentrates on middle part bellows, and smoke moisture is larger；Back segment bellows exhaust gas temperature is higher, and exhaust gas flow is big, oxygen content
It is gradually increasing, contains a large amount of dust；Sixth is that trolley, during circulation, grid section bears violent temperature change, Yi Fasheng
Deformation and scaling loss, service life six months to 1 year, need to periodically be replaced, consumption is larger；Seventh is that the burning of sintering machine tail portion
Molding contains the red mine of a large amount of high temperature, need to be equipped with cooling equipment and be cooled down again, low temperature exhaust heat can not effective recycling.
In conclusion existing sintering machine and its technique carry out shop fixtures, mixing charge level there are finished product mine is used continuously before cloth
It need to be carried out continuously that igniting, equipment attrition system air leakage point is more, discharge amount of exhaust gas is larger, cloth thickness of feed layer is low, UTILIZATION OF VESIDUAL HEAT IN
The disadvantages such as coefficient is low, and cooling equipment need to be configured, production run and maintenance cost are high.
