Description

Technical Field

[0001] The utility model relates to the technical field of construction and installation of vertical fire channel temperature measuring equipment in a coke oven combustion chamber, in particular to a coke oven temperature measuring lens installation and alignment device. Background Art

[0002] The vertical flue temperature of the coke oven's combustion chamber is an important factor that determines the quality and output of coke, as well as the service life of the coke oven. In recent years, in order to improve the accuracy and stability of temperature measurement and avoid errors in manual temperature measurement, the widely used temperature measurement method is to install the optical lens of the infrared temperature measuring device on a special furnace cover at the fire viewing hole on the top of the vertical flue furnace. During construction and installation, it is necessary to use an aiming device to fine-tune the position of the furnace cover so that after the lens is installed, the optical lens is aimed at the center of the three-dimensional triangle formed by the two nose bricks of the coke oven and the optical lens, and then the furnace cover is welded and fixed and the lens is installed on the furnace cover. In other words, the aiming of the lens is completed by the alignment of the furnace cover during installation;

[0003] The optical lens aiming device currently used for vertical fire channel temperature measurement uses a metal tube with a metal crosshair at one end for aiming. When in use, the end of the metal tube without the crosshair is inserted into the hole in the center of the furnace cover, and the alignment is completed by aiming with the crosshair. There are problems such as the structure of the aiming device is completely different from the optical lens of the lens, resulting in large errors after the lens is installed, the metal crosshair is opaque and blocks the aiming line of sight, and the high-temperature smoke in the furnace comes out along the metal tube and burns the operator's eyes during use, which affects the installation efficiency and installation accuracy. Therefore, we propose a coke oven temperature measurement lens installation and alignment device to solve the above problems. Utility Model Content
