Coke oven nose bridge brick temperature measuring device having aiming and aiming function and use method thereof

Abstract

The invention relates to a coke oven nose bridge brick temperature measuring device having an aiming and aiming function and a use method thereof. The device comprises a handheld displayer, an electronic imager, an infrared thermometer and an adjusting and locking mechanism. The signal output ends of the handheld displayer and the electronic imager are connected through a cable. The electronic imager and the infrared thermometer are coaxially arranged. The infrared thermometer is connected with the small oven cover on the top part of the coke oven vertical flue through the adjusting and locking mechanism. The infrared thermometer is internally provided with a cross sighting device. The adjusting and locking mechanism is composed of a shell, an elastic element, a centripetal universal ballbearing outer ring I, a centripetal universal ball bearing inner ring, a centripetal universal ball bearing outer ring II, protection glass and a sweeping connecting base. The device has the aiming and adjusting function, and the electronic imager and the handheld displayer are arranged to realize separated operation of observation and aiming so that operation is more convenient; and the adjustingand locking mechanism has the self-locking, locking force adjusting and dustproof and waterproof functions.

Description

technical field [0001] The invention relates to the technical field of temperature measurement of a fire path of a coke oven combustion chamber, in particular to a coke oven nose brick temperature measurement device with aiming and imaging functions and a method for using the same. Background technique [0002] At present, the coal coking industry generally uses portable infrared thermometers to manually inspect the temperature of the gas channel opening at the bottom of the fire channel of the coke oven combustion chamber and the nose bridge brick in the triangular area. Disadvantages such as time-consuming and laborious. In recent years, infrared on-line thermometers have been widely used. The instrument is installed on the small furnace cover of the vertical flue of the coke oven, but it cannot ensure that each instrument is aligned with the nose brick, which affects the precise control of the temperature in the flue of the coke oven combustion chamber. . [0003] The C...

AI Technical Summary

Problems solved by technology

[0004] 1) The method of aiming with the human eye and manually adjusting the lock is adopted. When locking, the human eye cannot leave the aiming hole, otherwise there will be "aiming-locking" operation deviation, and the deviation can be reduced through repeated adjustments, but the operation is cumbersome and time-consuming. strenuous;

[0005] 2) The centripetal ball joint in the locking mechanism works in a high temperature and vibration environment for a long time, so it is easy to loosen and cause aiming deviation;

[0006] 3) There is a gap on the top of the adjustment mechanism, and coal powder is easy to enter and accumulate, so that the centripetal ball joint cannot rotate and loses the adjustment function;

[0007] 4) Also because the top of the adjustment mechanism has a gap, when working in the open air, rainwater will enter the inside of the adjustment mechanism through the gap, pollute the protection window, and affect the accuracy of the temperature measurement by the thermometer
