Background technology
Blast furnace furnace roof infreared imaging device enters body of heater inside by the furnace roof pre-opened hole, is used to observe coal gas distributions situation and chute working order in the blast furnace.Because no visible light in the blast furnace, add dust greatly, high humidity, pressure is big, temperature is high, and camera head has been proposed higher requirement.From the running condition of present this type of device, have following problem: image definition is relatively poor; The pick up camera spectrum characteristic is relatively poor, just can see image when coal gas stream temperature is higher; The difficult problem of image contamination by dust camera lens is not effectively solved, and non-failure operation time is shorter; Pick up camera damages frequent; Can not on-line maintenance, direct motion exerts a certain influence to conditions of blast furnace.
Summary of the invention
The utility model provides a kind of effectively prevent dust pollution, resistant to elevated temperatures accumulatingdust blast furnace furnace roof infreared imaging device in the stove for solving above technique known problem.
Be in the state of high temperature, high pressure, high dust, high humidity in the State of Blast Furnace, make picture pick-up device on-line operation steadily in the long term in blast furnace, must solve heat insulation cooling, withstand voltage, prevent a series of technical barriers such as the sticking ash of eyeglass dewfall.
At first, blast furnace does not have visible light in the stove under production status, even add light source, because visible light can not penetrate the atmosphere of high dust, high humidity in the blast furnace, can't observe charge level situation in the stove with general camera system, must adopt special infrared technique.
Secondly, the furnace roof space is narrow and small, observe the situation of whole charge level, observe the working condition of chute or great bell again, must adopt specific wide-angle.
Once more, process units such as upcast and material chi are arranged on the top gas sealing cover, utilizable spare bits is equipped with limit, and camera head must miniaturization.
In sum, the utility model accumulatingdust blast furnace furnace roof infreared imaging device, form by camera, cooling system, gas leakage preventing device and camera temperature sensor:
Camera adopts pinhole lens, is convenient to protection, and the angle of view reaches 100 degree, the depth of field is long, need not focus; The camera microminiaturization is also adopted totally-enclosed metal shell.Install in the protection metal pipe of camera, the camera location adjusting device is housed, make the distance of camera and window adjust to the best; The CCD chip has visible light and infrared double function, and working stability is reliable, and the life-span is long.
Cooling system is made up of two-way cooling draught refrigerative passage and cyclic water jacket two portions.Camera is installed in the camera gun inner core, feeds cold gas between inner core and inner core and the water jacket, goes out the interruption-forming gas curtain at preceding protective sleeve, and one can lower the temperature, but two lens exempt from dust pollution, the protection camera.Preceding protective sleeve adopts conical design.The water jacket water-in is equipped with into that water sinks to the bottom pipe, water coolant is entered return behind the bottom top again, flows out from water outlet, has guaranteed cooling performance.
Gas leakage preventing device adopts Stainless Steel Ball Valve and gasket to cooperate.Gasket compresses expansion by the sealing internal thread, and sealing effectiveness is better.
Camera built-in temperature detecting sensor can be presented at the working temperature of camera on the thermometric instrument of master control room, when surpassing default safe working temperature, sends guard signal, reminds the watchstander to check.
Concrete formation comprises two portions: a part is onlinely to shift out the inner core of camera gun, and another part is the cooling guard shield of fixedlying connected with the blast furnace furnace roof.
The inner core that can onlinely shift out camera gun comprises camera, camera positioning regulator and temperature probe, and its lead-in wire is connected with aviation plug through the aviation plug Connection Block.
The cooling guard shield of fixedlying connected with the blast furnace furnace roof comprises: the water inlet pipe that the water jacket of hollow, water jacket have recirculated water inlet, circulating water outlet, sink to the bottom, water jacket front end be spirally connected removable before protecting jacket; One end of ball valve is connected with water jacket, and inner core passes ball valve, places water jacket central authorities; Inner core and water jacket inwall constitute outer cooling air flue, and aviation plug is fixed on the inner core upper end, and the side perforate of inner core upper end communicates with interior air flue inlet, constitutes the internal cooling air flue; Inner core top is connected and fixed by the other end of inner core set collar, inner core sealed screw, inner core set screw nut, gasket and ball valve.
Stop cooling gas to leak by compressing gasket, after inner core is extracted, close ball valve, stop the interior coal gas of blast furnace to leak.
During use, open ball valve, connect data line and get final product in the cooling guard shield that inner core is packed into the blast furnace furnace roof is fixedlyed connected.Simultaneously from cooling off air flue, water channel feeding cooling working medium.
The utlity model has and prevent dust pollution, accumulatingdust, resistant to elevated temperatures advantage in the stove, can be used for the monitoring of blast furnace furnace roof.
