Description

technical field [0001] The invention relates to: an installation device for making an infrared temperature measuring optical probe installed on a small furnace cover of a coke oven flue channel accurately aim at and lock the nose bridge brick at the bottom of the flue path for temperature measurement, which belongs to the optical temperature measurement coke oven thermal control field. Background technique [0002] The coal coking industry generally uses portable infrared thermometers to manually monitor the temperature of the fire channel of the coke oven combustion chamber; because the temperature of the gas channel at the bottom of the fire channel is different from that of the nose brick in the triangular area, the industry has formulated a requirement to "target the nose brick "Temperature measurement" unified process regulations. [0003] For the online temperature measurement of the coke oven flue, the infrared thermometer installed on the small furnace cover must fo...

[0006] 1) Application number: 200620071265.1 "Coke oven flue temperature non-contact online temperature measurement system" Chinese utility model authorized patent, the patent describes a simple "concept", the patent drawings are stick figures; there is no "aiming nose brick" "Temperature Measurement" description and implementation method; more than 30 emails between the patentee and Shanghai Synergy Institute of Physics (mails from December 29, 2005 to August 3, 2010, available in the computer server), Anhui The bank remittance certificate for the purchase of instruments by Huaye Automation Engineering Company of Industrial University and Ma'anshan Lantian Chemical Automation Technology Co., Ltd., the value-added tax invoice issued by Shanghai Synergy Institute of Physics for the sale of instruments, and the focal point attached to the paper published by the patentee The temperature measurement photos of the furnace show that before and after the patent application, the coke oven flue temperature non-contact online temperature measurement device selected by the patentee was designed by the Shanghai Synergy Institute of Physics. "Temperature measurement" structure and function;

[0007] 2) "Shanghai High-tech Achievement Transformation Project" in 2009, project number: 200907449, project name: "XTIR-F Fiber Optic Infrared Thermometer", project unit: Shanghai Synergy Institute of Physics; among the series products of this project , there is a model: XTIR-F915 fiber optic infrared thermometer, which is specially used for temperature measurement of coke oven flue. At that time, there was no special installation device for "targeting nose brick temperature measurement". After 2010, it was not promoted in the coking industry. ;

[0008] 3) Application number: 201020600087.3 The utility model authorized patent of "Infrared Radiation Temperature Measurement Optical System", the patentee: Anhui University of Technology and Taiyuan Coal Gasification Co., Ltd., before the application date, is the above-mentioned XTIR-F915 fiber optic infrared thermometer Purchase and user; the inventor of this patent disassembled the optical probe of the purchased XTIR-F915 instrument, arranged it according to the assembly order of the parts, surveyed and mapped it, and used it as a patent drawing; in the patent, there is such a description: In the "mirror "Apply" a film layer that completely reflects the target radiation band", and then look at the "size and position of the target image" on the "reticle" placed behind, and then "Use a magnifying glass to observe the target image above the fiber flange Whether it is in the center of the inner hole of the flange"; this is a wrong description that lacks common sense and professional knowledge; in terms of "targeting the temperature measurement of the nose brick", the patent has no description and innovative improvement;

[0009] 4) In 2010, the model: AHIR-F915 fiber optic infrared thermometer appeared, which cloned the above-mentioned XTIR-F915 fiber optic infrared thermometer. The cloning unit is Ma'anshan Lantian Chemical Automation Technology Co., Ltd., the company's legal representative, Anhui Industry University professor, once issued a written "user report" for the Shanghai Synergy Institute of Physics: Highly commented on the performance of the XTIR-F915 fiber optic infrared thermometer in measuring the temperature of the fire path; related scientific research papers, patents, and technological progress in Anhui University of Technology With the support of national awards and the national preferential policy of "School-Enterprise Horizontal Scientific Research Cooperation Project", the AHIR-F915 fiber optic infrared thermometer has been promoted and sold in the domestic coal coking industry, which has a great influence; but without innovation and improvement, it cannot "target the temperature measurement of the bridge of the nose" ;

[0010] 5) Application No.: 201210091489.9 Invention patent of "An On-Line Temperature Measuring Device and Measurement Method for Coke Oven Fume Passage", applicants: Maanshan Iron and Steel (Group) Holding Co., Ltd. and Maanshan Iron and Steel Co., Ltd., applying for A few days ago, I was the purchaser and user of the above-mentioned XTIR-F915 and AHIR-F915 fiber optic infrared thermometers. This patent "still draws a gourd" and clones the previous patent application number: 201020600087.3. "Wrong description" is also copied correctly; there is no innovation and improvement, and there is no description of "targeting the temperature measurement of the bridge of the nose brick"; among the many patent inventors, one is a professor of Anhui University of Technology, and the previous application number is: 201020600087.3 In the patent, he is also one of the inventors;

[0011] 6) Many iron and steel and coal coking enterprises in China are now using the AHIR-F915 fiber optic infrared thermometer to measure the temperature of the flue; The "infrared emissivity correction value" makes the temperature displayed by the temperature measuring instrument seem to be acceptable; therefore, on the same coke oven, the "infrared emissivity correction value" on each fire path temperature measuring instrument is "variety" Yes, from the perspective of scientific temperature measurement, there is a little "self-deception";

[0012] 7) At the end of 2013, in a coking enterprise in Shanxi Province, a new discovery was made: Raytek MI3 infrared thermometer from Fluke Company of the United States, and a portable infrared thermometer of model HDIR-5 as online instruments, installed in The temperature was measured on the small furnace cover, but it failed to "target the nose brick to measure the temperature";

[0015] a. In this patented technology, there is "the base (100) that is installed and can precisely align and lock the measurement direction of the optical probe"; the disadvantage is: "the structure is divided into two layers (101 and 102)", and there will be Accumulation of coal dust; the "base (100) that replaces the small furnace cover" will be very hot; several bolts (103) need to be tightened to lock the ball (105) in the base (100); these are not conducive to human hand contact and operations;

[0016] b. In this patented technology, there is a "signal processing display box (505) with a portable optical fiber infrared thermometer" and a "long arm aiming lever (500)" with temperature measurement function; the disadvantage is: "long arm There will be a beamsplitter in the optical sight (501) of the aiming lever (500)"; if a commonly used sheet-type coating beamsplitter is used, then when aiming at the bridge of the nose brick (small target) at a long distance, the "long arm aiming lever ( 500)" itself will also produce an offset error of the aiming point; moreover, a "portable fiber optic infrared thermometer" is bound to the "long arm aiming lever (500)", although it can measure temperature However, it is even more of a burden, and the disadvantages far outweigh the advantages;

[0017] c. In this patented technology, the shaft of the "long arm aiming lever (500)" adopts a peeping tube (502) with a length of 1.6 meters; the advantage is that the installer can stand and use the "long arm aiming lever (500)" The disadvantage of searching and aiming at the bridge of the nose is that you have to squat down, tighten the "bolt (103)", and lock the "ball (105)" in the "base (100)"; the operation method of this body position change will affect The stability of holding the "long-arm aiming lever (500)" brings about the deviation of "aiming-locking" operation, including the above-mentioned: the coaxial rotation of the "long-arm aiming lever (500)" itself produces an offset error of the aiming point
