Description
Technical field
The utility model relates to a kind of charge level detector, and particularly a kind of lime burner furnace charge level detector belongs in iron and steel, soda ash, the building materials industry lime and accompanies the burning technology field.
Background technology
Understand according to the applicant, lime burner furnace generally adopts the interior variation of temperature of temperature measuring equipment monitoring stove to measure the interior material level of stove indirectly at present.The serious hysteresis of this class material-level detecting device reaction can't in time reflect the normal material level in the stove, makes material level be difficult to control and adjusts to normal range, and the result causes influencing product quality.In addition, still have the minority lime burner furnace to use mechanical feeler lever to detect material level at present, its complex structure often occur faults such as screens during operation, and maintenance difficulty is very big, causes damage easily.Simultaneously,, cause kiln gas leakage unavoidably, influence environmental protection because mechanical feeler lever often moves.
Summary of the invention
The purpose of this utility model is: at the problem that above prior art exists, proposes that a kind of measurement range is big, easy to use, the lime burner furnace charge level detector of compliance with environmental protection requirements, thereby guarantees measuring accuracy, reduce maintenance, and easy to utilize.
In order to reach above purpose, lime burner furnace charge level detector of the present utility model comprises sniffer and mount pad, described sniffer is a radar detector, described mount pad is made up of ring flange and guide pipe, described radar detector is installed on the ring flange, one end of described ring flange and guide pipe is connected, and the other end of described ring flange or guide pipe is fixed on the lime burner furnace body of heater.
For fear of the operate as normal of Effect of Hyperthermic Environment radar detector, the utility model also adds stay-warm case.Described stay-warm case is provided with the cooling channel device, is fixed on the radar detector outside.
During work, radar detector is launched radar wave to the lime burner furnace material level, receives into the receiver of radar detector and after output shows, just can accurately directly measure the material level in the steel-making blast furnace stove hall when it reflects.Because radar detection is a non-contact measurement, therefore not fragile, need not safeguard that substantially its probe precision can reach 0.1%, range can reach 20m.And, lime burner furnace charge level detector and body of heater be connected with flange, do not have movable member, therefore can guarantee does not have leakage SO in the limekiln in
2Gas and dust, compliance with environmental protection requirements, easy to utilize.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the user mode synoptic diagram of Fig. 1 embodiment.
Embodiment
Embodiment one
The lime burner furnace charge level detector of present embodiment mainly is made up of radar detector 1, ring flange 2, guide pipe 3 and stay-warm case 4 as shown in Figure 1.This radar detector adopts the VEGAPULS56K of German VEGA company, comprises electronic unit 1-1, radar radiating tube 1-2, hydraucone 1-3.The upper end of hydraucone 1-3 is installed on the ring flange 2.
The upper end of guide pipe 3 and ring flange 2 are connected, and are furnished with the blow device 3-1 that connects source of the gas near 3 times end peripheries of guide pipe.Stay-warm case 4 covers on outside the radar detector 1, and the lower end also is fixed on the ring flange 2.One middle side part of this stay-warm case is provided with the instrument wind inlet 4-1 that inserts instrument wind, and the upper end is provided with instrument wind outlet 4-2.
During use, as shown in Figure 2, guide pipe 3 in the present embodiment lime burner furnace charge level detector is fixed on kiln 5 sides upper end.Kiln adds lime stone and coke solids compound by furnace roof.Usually the furnace roof normal temperature is about 300 ℃, and undesired reaching 400 ℃ spent more.Lime stone in the stove becomes pulverized limestone under the coke combustion, flow out from the kiln bottom.
The compound height of burner hearth lime stone and coke, be not only the important parameter that guarantees the not empty stove of furnace charge, discontented stove, and have only furnace charge is controlled at certain height, making that oxygen keeps certain ratio in coke and the stove, temperature in the stove could be controlled in the scope of technological requirement.Therefore must be to material level continuous detecting, control.
After adopting present embodiment, radar emission radar wave in the ironmaking lime burner furnace charge level detector on kiln top, arrive the interior iron ore of blast furnace and the compound charge level of coke and reflect, be that this radar receiver receives and output shows, thereby reach purpose the material level continuous detecting.This radar sensor can be high temperature resistant 400 ℃, and blow device then can in time be removed the dust that is deposited on the radar emission device, guarantees the stable emission of radar wave, also has the effect of auxiliary temperature-reducing simultaneously.The effect of stay-warm case is that the radar electric parts are incubated, and uses the instrument air cooling.Undesirable because of the insulation of many limekilns kiln top, radar is very high at the suffered radiation heat of furnace roof, and electronic unit might surpass 60 ℃, cisco unity malfunction because of being subjected to environment temperature.Then can guarantee the operate as normal of radar after the employing stay-warm case structure.
The lime burner furnace charge level detector that experiment showed, present embodiment is measured accurately, has desirable high-temperature working performance, and environmentally safe is easy to utilize.
In addition to the implementation, the utility model can also have other embodiments, for example adopts the radar of other models, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
