Abstract
The utility model relates to a detector that is used for checking the material level inside of the hearth of the iron-making high furnace. The utility model belongs to the iron making technical field of the iron & steel industry. The detector is composed of a detection unit and an installation seat. The detection unit is a radar detector and the installation seat is composed of a flange and a guide tube. The radar detector is arranged at the flange. The flange is connected and fixed with one end of the guide tube. The other end of the guide tube is fixed on the high furnace body. During working, the radar detector emits radar waves to the material surface inside the hearth of the iron-making high furnace, and then the radar waves are reflected back and received and displayed by the receiver of the radar detector and therefore the material level inside the hearth of the furnace is accurately and directly measured. Radar is non-contact measurement; therefore the detector is not easy to be damaged and basically does not require any maintenance. Besides, the instrument and the furnace body are connected by the flange, so that the instrument cannot move around, which ensures that no gas is leaked out of the high furnace, which is in accordance with the environment protection and is convenient to be popularized and applied.
Description
Technical field
The utility model relates to a kind of charge level detector, and particularly a kind of detector of iron-smelting blast furnace device burner hearth material level belongs to ironmaking technology field in the Iron And Steel Industry.
Background technology
Understand according to the applicant, detect the burner hearth material level on the present metallurgical iron-smelting blast furnace and generally adopt a kind of mechanical stock rod, its structure is numerous and diverse, often occurs slide calliper rule during operation, falls fault such as hammer, and blast furnace must stop production during maintenance, and the loss that causes therefrom is bigger.And the existing machinery stock rod generally can only measure 6 meters degree of depth, and blast furnace burner hearth material level uses needs up to 15 meters in order to satisfy, and usually has to the method for interim grafting stock rod, and is very inconvenient.In addition,, moving always, causing the leakage of blast furnace gas unavoidably, influencing environmental protection because the stock rod line passes furnace roof.
Summary of the invention
The purpose of this utility model is: proposes that a kind of useful range is big, easy to use, the iron-smelting blast furnace burner hearth 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, iron-smelting blast furnace burner hearth charge level detector of the present utility model comprises means of detection and mount pad, described means of detection 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 guide pipe is fixed on the blast furnace.
During work, behind the radar wave directive iron-smelting blast furnace burner hearth charge level that radar detector is launched, reflect, be the receptor reception and the output demonstration of radar detector, thereby accurately directly measure the material level in the iron-smelting blast furnace burner hearth.Because radar is a non-contact measurement, and is not fragile, need not safeguard that substantially its probe precision reaches 0.1%, range can reach 20m.And instrument is connected with flange with body of heater, does not have moving parts, therefore can guarantee not have blast furnace gas and leak, and 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 iron-smelting blast furnace burner hearth charge level detector of present embodiment mainly is made up of radar detector 1, ring flange 2 and guide pipe 3 as shown in Figure 1.This radar detector adopts the VEGAPULS56K of German VEGA company, comprises electronic unit 1-1, radar radiating pipe 1-2, and hydraucone 1-3 is installed on the ring flange 2.One end and the ring flange 2 of guide pipe 3 are connected, and are furnished with the blow device 3-1 that connects compressed air source near 3 times end peripheries of guide pipe.
During use, as shown in Figure 2, guide pipe 3 in the present embodiment iron-smelting blast furnace burner hearth charge level detector is fixed on iron-smelting blast furnace 4 sides upper end.Blast furnace adds iron ore and coke solids compound by furnace roof.Usually the furnace roof normal temps is about 300 ℃, and undesired reaching 400 ℃ spent more.Iron ore in the stove becomes molten iron under the coke incendiary effect, flow out from furnace bottom.
The compound height of burner hearth iron ore 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, make the certain ratio of oxygen maintenance in coke and the stove, temperature in the stove could be controlled in the scope of processing requirement.Therefore must be to the material level continuous detecting.
After adopting the utility model, radar emission radar wave in the iron-smelting blast furnace burner hearth charge level detector of furnace roof arrives the interior iron ore of blast furnace and the compound charge level of coke and reflects, and comes, for this radar receiver receives and the output demonstration, thereby reach purpose to the material level continuous detecting.This radar 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.
Experiment showed, the measurement of this enforcement iron-smelting blast furnace burner hearth material level charge level detector accurately, have the ideal high-temperature working performance, environmentally safe, 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.
