Description
Technical field：
The utility model is related to the automatic system with addition of red soil in a kind of sinter mixture, belongs to mixture of sintering machine moisture
Control technology field.
Background technology：
With the increase year by year of iron and steel output in recent years, steel-making produced pollution dust also rolls up.To reach ring
Guaranteed request, steel-making link realizes the recovery of pollution dust, and take on a red color slurry condition after the dust recovery of steel-making link, referred to as red
Mud.But, how to reuse the red soil of recovery but turns into another problem.Because iron content is higher in red soil, if will be red
Mud is added in the compound of sintering, can both improve the Fe and CaO content of compound, and reducing iron powder material proportioning can rise again
To the effect of regulation material moisture.But, prior art steelmaking red mud handling process is by manually operated simple with compound
Directly utilized after mixing for sintering, be that workman relies on according to the measured value of infrared moisture instrument and the situation on sintering feed surface mostly
Experience determine with addition of red soil number.When adding, red soil is excessive, the pH value reduction of sintering deposit（Alkalescence declines）, sintering deposit granularity pine
Dissipate, the porosity increases, intensity declines, and causes the fluctuation of sinter quality；When add red soil amount it is few when, the moisture of compound is again not
Foot, and then influence smelting weight of iron.Or added water using primary mixer or red soil method control sinter mixture moisture, and
Flow is controlled using on-site manual mode, the moisture fluctuation of compound greatly and also can not compensation adjustment, compound is most made at last
Granularity effect be deteriorated, gas permeability is deteriorated, and causes sintering velocity to slow down, and forces preparation coal dust amount increase, rate of return mine rise, sintering
Ore deposit quality, yield decline in pairs, are that the compound of overdrying and overly moist makes central control system can not accurately control sintering end point what is more,
Cause inestimable serious accident.The infrared moisture instrument measurement mixture moisture used in existing compound system, compound
Surface state, color, structure can all influence to disturb ultrared reflectivity matches somebody with somebody in the measurement of moisture, such as sinter mixture
Plus red soil, material color and structure be different from not plus during red soil, and this can influence the collection of infrared moisture instrument to measure the accurate of wavelength
Property, so as to influence measurement accuracy.

Moisture is adjusted, then sintering machine is sent to by two mixed rear belt feeders, rear material all in one piece device carries out material all in one piece, and rear microwave moisture instrument detects material
Moisture.
The utility model effectively solves burning by improving or increasing a series of means such as equipment and Site Detection mode
Tie compound reduces with addition of possible caused sintering deposit pH value during red soil, and sintering deposit granularity is loose, and the porosity increases, intensity
The problems such as decline, while the generation by flexibly controlling to be effectively shielded from siccative and material-mud.After production application
The situation of feedback shows：State on the implementation after equipment, primary mixer sizing no longer occurs and shuts down phenomenon, material head material tail water point
Can be up to standard, it is finally that mixture moisture value is continual and steady in acceptability limit, it is ensured that the high-quality of sintering deposit production.
The beneficial effects of the utility model：It can accurately control with addition of red soil flow, be adjusted at any time after being fed back by moisture
The final moisture of compound is saved, the purpose of continual and steady compound dry and wet degree is reached.Simultaneously as red soil is by effective profit
With not only reducing the proportioning of the smart iron material in part, reduce sintering deposit cost, be also greatly reduced steel-making enterprise to outside
Pollutant emission, has reached good environment protecting.
