Blast furnace inner high temperature industrial TV device

Abstract

The invention relates to a TV system for special applications, in particular to a high-temperature industrial TV device in a blast furnace that requires a probe (built-in camera and pinhole lens) to be probed into the furnace for real-time monitoring. Including the probe, it is characterized in that: a cooling base for protecting the probe is installed in the front of the probe, a flange for fixing the probe and sealing is installed in the middle of the probe, and a rotating base is installed in the rear of the probe The pan-tilt of the probe is equipped with a transmission mechanism for moving the probe and fixedly connected with the cooling base and the pan-tilt under the pan-tilt. The present invention adopting the above-mentioned technical scheme solves two technical problems, that is, it effectively prevents gas leakage in the blast furnace, avoids unsafe factors in production, facilitates the maintenance and debugging of operators, and better utilizes the gas in the furnace. The role of high temperature industrial TV, and then achieve better monitoring effect.

It is directly welded to the outer wall of the furnace mouth. At this time, the observation hole at the front of the probe is sealed to prevent the leakage of gas and harmful gases.

Problems solved by technology

[0002] Usually, after the high-temperature protection probe enters the furnace, in order to prevent the leakage of harmful gas (coal gas) in the blast furnace during the commissioning or maintenance process of the blast furnace gas, the protection probe must be sealed with the furnace wall, but usually only the water-cooled gas is simply sealed to the protection probe. It is directly welded to the outer wall of the furnace mouth. At this time, the observation hole at the front of the probe is sealed to prevent the leakage of gas and harmful gases. It is not absolutely isolated from the outside world. If the air pressure drops during maintenance, it may cause gas leakage. Hazard to personal safety

At the same time, because the protective probe enters the furnace and is directly welded to the furnace wall, the probe is not only easily polluted by dust in the furnace, but also has complex and difficult problems in equipment maintenance, debugging and equipment maintenance.
