Description

technical field [0001] The invention relates to a protection device for a blast furnace infrared thermal imager. Background technique [0002] At present, infrared thermal imaging technology is quite mature, and its application fields are also very wide. Due to the particularity of the blast furnace smelting environment, such as high pressure, high temperature, high dust, and total airtightness, high requirements are placed on the protection technology of blast furnace infrared thermal imaging cameras. The blast furnace infrared thermal imager equipment currently in use is used to monitor the top material surface and internal equipment of the blast furnace. [0003] The structure of the blast furnace infrared thermal imager protection device currently used in China is as follows: figure 1 As shown, it mainly includes a thermal imager protective cover 101 ′, a first flange 102 ′, a closed straight plate valve 103 ′, a second flange plate 108 ′, and a blocking straight plate...

AI Technical Summary

Problems solved by technology

[0005] The blast furnace infrared thermal imaging camera protection device mainly has the following disadvantages, which makes the effective running time of the infrared thermal imaging camera monitoring system in the normal production of the blast furnace very short:

[0006] 1. Although there are two airflows in front of the observation window for dust prevention, the airflow is output from the air outlet on the flange, and the airflow distribution is uneven. At the same time, due to the strong airflow and high dust in the blast furnace, the observation window is still easy to stick to dust

In the actual use process, it was found that the dustproof ability of the blast furnace infrared thermal imaging camera protection device is weak, and the observation window is easy to accumulate dust, which makes the observation window unable to pass through the infrared light, resulting in the loss of the monitoring function of the thermal imaging camera equipment and affecting normal production.

[0007] 2. The protective cover 101' of the thermal imager is fixedly installed. When the observation window is covered with dust, the observation window can only be cleaned by manually removing the protective cover 101' of the thermal imager, which is neither convenient nor safe. Frequent disassembly and assembly may easily cause equipment damage
