Abstract
Observing device in hot furnace of the present invention, around with the water quench inboard, portion emits in the shell (2) of tempering air and is equipped with in the observing device in hot furnace of video camera (1) within it, to the light path of video camera (1), dispose quartz glass (6) hotline-reflective glass (7) at light in turn from the front incident of shell (2), heat absorption glass (8), hot line sees through mirror (9), at shell (2) but the illuminating lamp (13) of former configuration far distance controlled brightness, temperature in the camera housing (2) is remained on below 50 ℃, and prevent from video camera (1) to be caused damage from the radiant heat of glass, by the brightness of remote control illuminating lamp (13), can carry out observation in the hot stove in the scope of normal temperature to 1200 ℃.
Description
The invention relates to the observing device in hot furnace of damage status of the interior refractory material of stove of the kiln of observing coke-fired furnace, blast furnace, torpedo hot metal mixer car, pot, converter, vacuum degasser etc. etc.
Usually, refractory material lining in the stove of kilns such as coke-fired furnace, blast furnace, torpedo hot metal mixer car, pot, converter, vacuum deaeration device etc., loss gradually when operation.Therefore, be thinned to the degree that is difficult to carry out operation, must often observe the damage status of refractory material in the stove for lining is unlikely.
In the past,, camera housing be made two water-cooling structures, be adopted to the indoor mode that blasts tempering air of video camera in order to observe the damage status of refractory material in so hot stove.
But, only camera housing is made two water cooling structures, blast the such observing device in hot furnace of tempering air to the photography unit room, in the high temperature field more than 900 ℃, make the inside damaged of video camera from the radiant heat of photography machine side, and the automatic focusing of video camera on the market, its allowed temperature range is 900 ℃-1,200 ℃, so, be difficult to observe fully.
The present invention develops in order to address the above problem, its purpose is to provide can use the city dealer television camera that can adjust focal length at a distance, can prevent from video camera to be caused damage from the radiant heat of glass, and can be at normal temperature to 1, the observing device in hot furnace of observing in 200 ℃ of temperature ranges.
Observing device in hot furnace of the present invention, around the water quench inboard, simultaneously, in the housing of emitting tempering air to inside, keep in the observing device in hot furnace of video camera, it is characterized in that, from the light of housing front incident to the light path of video camera, quartz glass, hotline-reflective glass, heat absorption glass, hot line are installed are in turn seen through mirror, simultaneously, but the illuminating lamp of far distance controlled brightness is set in the housing front.
Device is with in around the water quench inboard in the hot stove of the present invention, in the housing of emitting tempering air to inside, keep in the observing device in hot furnace of video camera, from the light of housing front incident to the light path of video camera, dispose quartz glass in turn, hotline-reflective glass, heat absorption glass, hot line sees through mirror, simultaneously, but the illuminating lamp of far distance controlled brightness is set in the housing front, like this, make and remain on below 50 ℃ in the video camera housing, thereby can prevent from video camera to be caused damage from the radiant heat of glass, the brightness of illuminating lamp is carried out the damage of remote control, so that can be at normal temperature to 1,200 ℃ temperature range be to observing in the hot stove.
Accompanying drawing is the presentation graphs of expression according to an embodiment of observing device in hot furnace of the present invention.
With reference to the accompanying drawings one embodiment of the invention are described below.
Accompanying drawing is the presentation graphs of expression according to an embodiment of observing device in hot furnace of the present invention, and 1 is video cameras among the figure, the 2nd, the video cameras shell, the 3rd, the camera housing stay pipe, the 4th, tap, the 5th, the draining larynx, the 6th, quartz glass, the 7th, hotline-reflective glass, the 8th, heat absorption glass, the 9th, hot line sees through mirror, the 10th, cooling air passes through the slit, the 11st, the cooling water inlet, the 12nd, the compressed air inlet, the 13rd, illuminating lamp, the 14th, the brightness regulation transformer, the 15th, temperature sensor, the 16th, heat indicator, the 17th, the straighforward operation case, the 18th, surveillance television, the 19th, register.
Among the figure, the 11 water quench stay pipes 3 that flow into from the cooling water inlet flow into video cameras shell 2 these shells of cooling by tap 4, flow out from draining larynx 5 then.
In addition, the inside of 12 leaked-in airs cooling camera housing 2 is released to the outside by the slit 10 around the glass system of being made up of quartz glass, hotline-reflective glass, heat absorption glass then from the compressed air inlet.The combination of this glass system is quartz glass 6, heat-reflecting glass 7, heat absorption glass 8 from the outside in turn, maintains the gap that is about 2mm between them, and the cooling to glass is carried out in cooling air this gap of flowing through effectively.
Enter into light in the housing from glass, at first by quartz glass 6, and by the 800nm(nm=1/1000 μ m of heat-reflecting glass 7 reflections about 90%)-long wavelength's light of 900nm.Then, enter in the light of heat absorption glass 8, wavelength is that the above light of 90nm has about 97% to be reflected or to absorb, and the light by here sees through the light that mirror 9 sees through long wavelength wherein by hot line, has only visible light to be reflected to video cameras 1.Like this, the image that is observed is shown in surveillance television machine 18, simultaneously, as required, goes on record at register.Moreover video cameras 1 can freely be adjusted focal length at a distance by the operation of remote control box 17.
Temperature in the housing is detected by temperature sensor 15, and often monitored by heat indicator 16, cooled off by above-mentioned cooling water, cooling air, do one's utmost to prevent that hot line from being entered by window, temperature in the housing can be remained on below 50 ℃, simultaneously, can prevent that also radiant heat from causing damage to video camera.
Also have, built-in video camera has the function of automatic focusing, and its temperature range of allowing is 900 ℃-1,200 ℃.The there is provided with illuminating lamp 13, and by regulating with transformer 14, the remote control supply power voltage can expand to normal temperature with the low temperature side of allowed temperature range to regulate its brightness.
As mentioned above, according to the present invention, the temperature in the housing of collection video camera is remained on below 50 ℃, prevent simultaneously from the radiant heat of glass surface photography injury, the heat resisting temperature of video camera can be brought up to 1,200 ℃ from original 900 ℃. Also have, by the brightness of straighforward operation control illuminating lamp, can be at normal temperature to 1,200 ℃ temperature range is carried out the observation in the hot stove.
As mentioned above, the present invention be applicable to use can remote control focal length city dealer television camera, prevent the damage that the radiant heat of glass surface causes video camera, at normal temperature to 1,200 ℃ temperature range is carried out the observation in the hot stove.
