Abstract
The utility model relates to a camera device in a refining furnace. A protective sleeve and an interlayer form a circulating water cooling space, and turbulence plates are distributed in the space along the axial line of the protective sleeve. An end cover combined with the protective sleeve in a sealing way and provided with a line outgoing port is arranged at the rear end of the protective sleeve, the line outgoing port is connected with a pipeline sheathed in a video signal output wire cable and a power wire cable in a sealing way, the pipeline is provided with a three-way connector, wherein, one end of the three-way connector is connected with a cooling air source. A two-level wavelength nominal optical filter for filtering bright light is arranged at the rear part of a composite lens. The device adopts the technical measures that the positive pressure cooling gas is introduced into the external water-cooling interlayer and the interior, so that the camera device can constantly and normally work in the furnace under the environment of high temperature and serious dust, and provides necessary equipment conditions for observing the smelting conditions of the refining furnace at any moment, as well as implementing real-time controlling or processing. The camera device has the advantages that the camera device in the refining furnace can constantly and normally work, the resolution of the high brightness image is obviously enhanced, and the operation is convenient.
Description
Technical field
The utility model belongs to camera head, particularly relates to a kind of refining furnace photographic device inside.
Background technology
In the prior art; the formula camera head of probeing into is the capital equipment that is used to observe smelting situation in the refining furnace, and camera and visual signal of telecommunication output cable that its primary structure feature is converted to the visual signal of telecommunication by the common imaging lens of single ply protective cover, protective sleeve leading section, with optical image are formed.The described formula camera head using method that probes into is the short time to probe into refining furnace, withdraws from immediately.
Obviously there is following defective in the above-mentioned formula camera head that probes into: the time that probes into refining furnace observation smelting situation is essential of short duration, otherwise furnace high-temperature will damage this camera head, therefore this camera head can not be realized continuous monitoring in the stove, is unfavorable for the refining furnace situation of smelting is in time implemented control or processing; Common imaging lens can not adapt to the environment for use of brightness wide variation in the stove, and the complete white image of image resolution-ratio extreme difference even appearance was crossed bright image and made operating personnel can't observe smelting situation in the stove when particularly brightness was higher.
Summary of the invention
The utility model is existing probe into the above-mentioned open defect that the formula camera head exists and propose a kind of refining furnace photographic device inside in order to solve.
The utility model is taked following technical scheme for realizing its purpose: this stove photographic device inside is by protective sleeve; the imaging lens of protective sleeve front end; optical image is converted to camera and the vision signal output cable and the power cable composition of the visual signal of telecommunication; it is characterized in that: described protective sleeve is provided with interlayer; the interlayer front end is provided with the via hole with protective sleeve front aperture coaxial line; constitute the recirculated cooling water space between protective sleeve and the interlayer; the protective sleeve rearward end is arranged with cooling water and goes into delivery port; the protective sleeve rear end is provided with its sealed engagement; the end cap that has line outlet; outlet port sealing is connected with the pipeline that is set in vision signal output cable and power cable; the three-way connection that is connected in this a pipeline wherein end joins with the cooling source of the gas, and the other end is drawn vision signal output cable and power cable.
The utility model can also be taked following technical measures:
The recirculated cooling water space that described protective sleeve and interlayer constitute is provided with the turbulence plate that distributes along the protective sleeve axis.
Described imaging lens is made of the filter set at the compound lens in the shell with front aperture, the shell, compound lens rear portion, and described filter set is by the two-stage Wavelength calibration filter of packing ring interval, filtering high light.
The beneficial effects of the utility model and advantage are: this stove photographic device inside adopts the technical measures of outside water-cooled interlayer, inner logical people's malleation refrigerating gas, enable under furnace high-temperature, strong dust atmosphere, to continue operate as normal, provide necessary appointed condition for observing refining furnace smelting situation, enforcement control in time at any time or handling.The turbulence plate of water-cooled interlayer setting not only helps recirculated cooling water and arrives the protective jacket top fast, also helps the raising heat exchange efficiency.The imaging lens of this camera head is set up the two-stage filter of filtering high light, the disadvantage of display terminal image resolution-ratio variation in the time of can avoiding high light effectively, thus improved the definition that image shows.The utlity model has shooting and lasting operate as normal, the obvious raising of high-brghtness picture images resolution and outstanding advantage easy to use in the stove.
