Description
Technical field
The present invention relates to metallurgy sintered mine transportation system and cooling systems, and in particular to a kind of board-like delivery chute of high temperature, defeated
Machine and a kind of sintered ore cooling system are sent, metallurgy sintered mine device field is belonged to.
Background technique
Apron conveyor be using closure, circular flow chain as driving component, with docking or that overlapped is parallel
The conveying equipment of plate, waveform plate and the components such as groove profile or box as bearing carrier.Apron conveyor is not only suitable for defeated
Bulk granular material is sent, and is suitable for conveying work piece.In its of metallurgy, coal, chemical industry, electric power, machine-building and national economy
It is widely used in his industrial department.
There are sintering mine sensible heat (ring cold machine exhaust gas) and sintering device flue gas sensible heat two parts residual heat resources in conventional sintering technique.
Sintering device flue gas is because temperature is low and seldom, most of current country's iron and steel corporation containing impurity UTILIZATION OF VESIDUAL HEAT INs such as various S, P
It is generated electricity using waste heat boiler recycling sintering mine sensible heat steam (ring cold machine exhaust gas).Domestic ring cold machine UTILIZATION OF VESIDUAL HEAT IN is only capable of recycling
High temperature, two sections of middle-temperature section of waste heat, low-temperature zone exhaust gas is not utilized, and air leak rate of air curtain is higher, and it is cold to be only capable of recycling 40% or so
But area's higher temperature hot waste gas waste heat, residual heat resources recovery utilization rate are lower.
To overcome, the generally existing air leak rate of air curtain of sinter cooler run at present is high, hot waste gas grade is low and residual heat resources are returned
Receive the problems such as utilization rate is low, my company is quasi- to use for reference Dry Quenching Technology and develop a kind of new-type vertical cooling machine to substitute current ring type cold
But machine.The vertical cooling machine uses reverse heat-exchange, and sinter enters from cooler top, lower part discharge；Cold air is from cooler
Lower part blast pipe is extracted out into figure, top.Can make in this way heatrejection from the part of traditional ring type using become all of,
And improve the outlet temperature of hot waste gas.The utilization rate of waste heat of heat sinter can be improved to 70% or so.
Because the discharging point of place limitation sintering machine cannot fall directly into vertical cooling machine, and vertical cooling machine height is higher,
There can be certain height difference with sintering machine discharging point.According to technology arrangement, it is high that a transport is needed to configure at sintering machine discharging point
Material is delivered to vertical cooling machine feeding inlet by the conveyer of warm sinter.And sinter heat is as far as possible during transportation
Loss is reduced in favor of later use.Apron conveyor is all open type, transport high temperature material, in transportational process in the prior art
Middle material and air carry out heat exchange and mainly pass through top, bottom and two sides loss.In addition, clinker mineral material granularity size is not
One, bulk can reach 300mm, and minimum only has several millimeters, and with certain powder.The board-like conveyor construction of traditional bulk cargo is adopted
With the board-like delivery chute of waveform.Traditional bulk cargo apron conveyor carrier chain does not have self-locking limiting device, can between two pitch chain items
Biggish subtended angle can occur.Such as two neighboring delivery chute discontinuity (transported material weight is different), then it is likely to occur defeated
The case where sending slot mutual extrusion causes to deform.As long-term extruding be deformed it is excessive will lead to conveyer material leakage, shorten conveyer
Time between overhauls(TBO) reduces the service life of delivery chute.
