Embodiment
Please, the structural representation of blast furnace 100 according to an embodiment of the invention has been shown among the figure with reference to Fig. 1.Blast furnace 100 comprises body of heater 110, air-blast system 120 and camera system 130.Body of heater 110 is in order to receiving raw materials such as iron ore, coke, and in interior, carries out redox reaction the iron in the iron ore is restored.In body of heater 110, charcoal and ore form the alternatively layered structure.Ore charge progressively is reduced, is fused into iron and slag in the decline process, accumulate in the cupola well, regularly emits from iron notch and slag notch.In the present embodiment, body of heater 110 includes furnace roof portion 112 and stove bottom 114, and wherein iron ore is fed in the body of heater 110 by furnace roof portion 112, and molten iron is then discharged from the iron notch 116 of stove bottom 114.Air-blast system 120 is in order to provide redox reaction required oxygen.In the present embodiment, air-blast system 120 is sent into the air in the external world in the body of heater 110 with the high pressure mode, with the promotes oxidn reduction reaction.Camera system 130 is set at furnace roof portion 112, in order to observe the response situation in the body of heater 110.
Please the internal structure synoptic diagram of furnace roof portion 112 be shown among the figure simultaneously with reference to Fig. 2 a and Fig. 2 b.In the present embodiment, furnace roof portion 112 is provided with manhole 118, and camera system 130 then is arranged near the manhole 118, for example, is arranged at manhole 118 tops, and is as shown in Figure 2.Though, with regard to install and the accessibility of maintenance with regard to, being arranged near the manhole 118 is a good selection, 130 zones that can observe of camera system are very limited.Therefore, also can be chosen in preferable place, other visual field camera system 130 is set, shown in Fig. 2 b.
Please, the cross-sectional view of camera system 130 has been shown among the figure with reference to Fig. 3.Camera system 130 comprises image unit 131, housing 132, clean gas feeding mechanism 133, vortex generating means 134, housing 135, radiator element 136, cooling gas feeding mechanism 137 and heat insulation loop 138.Image unit 131 is in order to the intravital image of shooting stove, and sends this image to the blast furnace operating personnel, for the response situation of ore in operator's analytical furnace.Housing 132 has chamber 132a, in order to ccontaining image unit 131.Chamber 132a has opening 132b, and image unit 131 can see through this opening 132b and take the intravital image of stove.Clean gas feeding mechanism 133 is set on the housing 132, in the chamber in order to ejection clean gas to housing 132, so that clean gas flows through stream generation apparatus 134.This clean gas is with the direction ejection of high pressure mode toward opening 132b.Vortex generating means 134 is set on the inwall of chamber 132a, and the clean gas that is sprayed in order to guiding clean gas feeding mechanism forms eddy current, and makes this eddy current impact the dust of opening part.In the present embodiment, vortex generating means 134 is to be made up of a plurality of inducer, when clean gas flows through inducer, can produce air whirl toward opening 132b diffluence, and the dust of so being piled up on the opening 132b just can receive the brute force impact of eddy current and divest.In addition, vortex generating means 134 is set near the opening 132b, and the eddy current that is so produced by vortex generating means 134 can flow out from opening immediately, to reach powerful removing effect.
Because the stackeding speed of dust is also unhappy, clean gas feeding mechanism 133 can spray clean gas according to preset cleaning cycle, to save the consumption of clean gas and electric power.For example, clean gas feeding mechanism 133 is connected on the blast furnace programmable computer, so clean gas feeding mechanism 133 can come automatically to spray clean gas according to the cleaning cycle that the blast furnace programmable computer sets, to remove dust.
Can know by above-mentioned explanation; The camera system 130 of present embodiment can be divided into two parts; First part comprises housing 132, clean gas feeding mechanism 133 and vortex generating means 134; In order to the dust on the removing camera system 130, and second part comprises housing 135, radiator element 136 and cooling gas feeding mechanism 137, in order to reduce the temperature of camera system 130.See through these two portions, camera system 130 not only can automatically be removed the dust of being piled up on the camera system 130, and the mechanism of high temperature protection also can be provided the image unit 131 of inside, protects image unit 131 to avoid pyritous and disturbs.
It should be noted that in the above embodiment of the present invention housing 135, radiator element 136 only are in order to illustrating, any other temperature protection mechanism all can be applicable in the camera system 130, so the present invention is not limited to above description.
Though disclosed a plurality of embodiment of the present invention in the preceding text; But these embodiment are not in order to limit the present invention; Those skilled in the art in the invention; Do not breaking away from the spirit and scope of the present invention, can make various changes and modification to the present invention, so protection scope of the present invention should be as the criterion with the scope that accompanying claims were defined.
