Description

Technical Field

[0001] This utility model relates to the field of integrated furnace gas steelmaking temperature monitoring technology, and in particular to a dynamic steelmaking temperature monitoring device with integrated furnace gas analysis. Background Technology

[0002] Integrated furnace gas steelmaking temperature monitoring refers to the real-time monitoring of the furnace temperature during the steelmaking process using specific technologies. This ensures that smelting takes place within a suitable temperature range, thereby improving production efficiency and product quality. Traditional integrated furnace gas steelmaking temperature monitoring methods involve using spectrometers and infrared thermal imagers. Spectrometers infer temperature by measuring the spectrum emitted from the furnace surface and are suitable for high-temperature environments. Infrared thermal imagers infer temperature by measuring infrared radiation from the furnace surface and are suitable for non-contact, long-distance, and precise temperature measurement. Infrared thermal imagers have high high-temperature adaptability and long-term stability, making them suitable for measuring the surface and internal temperature of steelmaking furnaces.

[0003] Currently, most integrated furnace gas analysis dynamic steelmaking temperature monitoring devices on the market are prone to infrared thermal imager malfunctions after prolonged use, making it impossible to repair the infrared thermal imager and thus increasing the workload of operators. At the same time, existing infrared thermal imagers are not convenient for operators to move or fix, which causes inconvenience to operators. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that most integrated furnace gas analysis dynamic steelmaking temperature monitoring devices on the market, as mentioned above or in the existing technology, are prone to malfunction of infrared thermal scanners during long-term use, making it impossible to repair them and thus increasing the workload of operators. In addition, existing infrared thermal scanners are not convenient for operators to move or fix, which causes inconvenience to operators.

[0006] Therefore, the purpose of this invention is to provide a dynamic steelmaking temperature monitoring device that integrates furnace gas analysis.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dynamic steelmaking temperature monitoring device integrating furnace gas analysis, comprising a device frame, a support frame installed at the top of the device frame, a push rod installed at one end of the top of the device frame, a lifting mechanism provided on the side wall of one end of the support frame, a fixing plate provided on one side wall of the lifting mechanism, a support plate installed on one side wall of the fixing plate, a first hinge seat installed at the top of the support plate, a second hinge seat hinged inside the first hinge seat, and an infrared temperature scanning camera installed at the top of the second hinge seat, a support fixing mechanism installed at the bottom of the device frame, an alarm installed on one side wall of the support plate, and caster wheels installed at the bottom of the device frame.

[0008] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, the lifting mechanism includes an installation groove and an installation box. The installation groove is opened on the side wall of one end of the support frame. A first installation block is provided inside the installation groove, and one end of the first installation block is fixedly connected to the side wall of the fixing plate. A first sliding groove is opened on one side wall inside the installation groove, and a first slider is provided inside the first sliding groove. The side wall of the first slider is fixedly connected to the side wall of the first installation block.

[0009] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, the mounting box is fixedly installed on the top of the support frame, a drive motor is installed at the top of the interior of the mounting box, and a threaded rod body penetrating the first mounting block is installed at the output end of the drive motor, the threaded rod body being threadedly connected to the first mounting block.

[0010] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, wherein: the interior of the fixing plate is equipped with bolt bodies.

[0011] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, the supporting and fixing mechanism includes a positive and negative screw body, which is rotatably installed inside the device frame through bearings. A threaded sleeve is threadedly connected to the outer wall of the positive and negative screw body, and a rotating rod is hinged to the bottom end of the threaded sleeve. A second mounting block is hinged to the bottom end of the rotating rod, and a turntable body is installed at one end of the positive and negative screw body.

[0012] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, the outer wall of the second mounting block is provided with a base plate, and the interior of the base plate is provided with a rectangular groove. The second mounting block and the rectangular groove cooperate with each other. The side walls on both sides of the interior of the rectangular groove are provided with second sliding grooves, and the interior of the second sliding grooves is provided with second sliders. The side wall on one side of the second slider is fixedly connected to the side wall of the second mounting block.

[0013] As a preferred embodiment of the dynamic steelmaking temperature monitoring device for integrated furnace gas analysis of this utility model, a temperature data analysis device is installed on one side wall of the support frame, and a temperature data report display screen is installed on one side wall of the support frame.

[0014] The dynamic steelmaking temperature monitoring device integrating furnace gas analysis of this utility model has the following beneficial effects:

[0015] This invention first uses a drive motor to rotate the threaded rod body. The threaded rod body is threadedly connected to the first mounting block. Through the cooperation of the first sliding groove and the first slider, the rotation of the threaded rod body causes the first mounting block and the fixing plate to rise and fall on the outer wall of the threaded rod body. This allows the height of the infrared temperature scanning camera to be adjusted by the raising and lowering of the first mounting block and the fixing plate, thus facilitating the operator's maintenance of the infrared temperature scanning camera.

[0016] This invention firstly rotates the main body of the positive and negative lead screws, which are threadedly connected to the threaded sleeves. This rotation causes the two sets of threaded sleeves to slide in opposite directions, thereby rotating the rotating rod. Furthermore, the second slide groove and the second slider cooperate to rotate the rotating rod, causing the second mounting block to slide through the second slider inside the second slide groove and raising or lowering the base plate. This raising or lowering of the base plate positions and fixes the device frame, making it easier for operators to operate.

[0017] This invention first uses an infrared temperature scanning camera to infer temperature by measuring infrared radiation on the furnace surface. The infrared temperature scanning camera can also perform comprehensive real-time temperature measurement of key locations in the steelmaking furnace, using the temperature data to assess the health of the lining. Simultaneously, a temperature data analysis device analyzes the temperatures measured by the infrared temperature scanning camera, generating a database from the collected temperature data to analyze temperature change trends. Abnormalities are automatically detected by an alarm. The system can also be configured with multiple alarm thresholds; exceeding these thresholds triggers an alarm. Furthermore, the measured temperature rise and fall can be displayed on a temperature data report screen. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0029] Example 1: Refer to Figures 1-5 This is the first embodiment of the present invention, which provides a dynamic steelmaking temperature monitoring device with integrated furnace gas analysis. It can achieve the functionality of most current integrated furnace gas analysis dynamic steelmaking temperature monitoring devices on the market. However, with prolonged use, the infrared thermal scanner is prone to malfunction, making maintenance impossible and increasing the workload of operators. Furthermore, existing infrared thermal scanners are not easy for operators to move or fix, causing inconvenience. The device includes a frame 1, a support frame 2 mounted on the top of the frame 1, a push rod 3 mounted on one end of the top of the frame 1, and a lifting mechanism 4 on the side wall of one end of the support frame 2. A fixing plate 5 is provided on the side wall of the device frame 1. A support plate 501 is installed on the side wall of the fixing plate 5. A first hinge seat 502 is installed on the top of the support plate 501. A second hinge seat 503 is hinged inside the first hinge seat 502. An infrared temperature scanning camera 504 is installed on the top of the second hinge seat 503. A support fixing mechanism 6 is installed at the bottom of the device frame 1. An alarm 505 is installed on the side wall of one end of the support plate 501. A caster wheel body 101 is installed at the bottom of the device frame 1. A bolt body 506 is installed inside the fixing plate 5. A temperature data analysis device 201 is installed on the side wall of one side of the support frame 2. A temperature data report display screen 202 is installed on the side wall of one side of the support frame 2.

[0030] The specific working principle is as follows: First, the infrared temperature scanning camera 504 infers the temperature by measuring the infrared radiation on the furnace surface. The infrared temperature scanning camera 504 can also perform comprehensive real-time temperature measurement of key locations in the steelmaking furnace. The temperature data is used to determine the health status of the lining. At the same time, the temperature data analysis device 201 analyzes the temperature measured by the infrared temperature scanning camera 504 and generates a database by collecting temperature data from various areas. The temperature change trend is analyzed, and an alarm is automatically triggered by the alarm 505 if an anomaly occurs. The system can also set multiple alarm thresholds, and an alarm will be triggered if the temperature is exceeded. The measured temperature rise and fall can be displayed on the temperature data report display screen 202.

[0031] Example 2: Refer to Figures 1-5 In the first embodiment of this utility model, the lifting mechanism 4 includes a mounting groove 401 and a mounting box 406. The mounting groove 401 is formed on the side wall of one end of the support frame 2. A first mounting block 402 is provided inside the mounting groove 401, and one end of the first mounting block 402 is fixedly connected to the side wall of the fixing plate 5. A first sliding groove 404 is formed on one side wall inside the mounting groove 401, and a first slider 405 is provided inside the first sliding groove 404. The side wall of the first slider 405 is fixedly connected to the side wall of the first mounting block 402. The mounting box 406 is fixedly installed on the top of the support frame 2. A drive motor 4061 is installed on the top of the mounting box 406, and a threaded rod body 403 penetrating the first mounting block 402 is installed on the output end of the drive motor 4061. The threaded rod body 403 is threadedly connected to the first mounting block 402.

[0032] The specific working principle is as follows: when the height of the infrared temperature scanning camera 504 needs to be adjusted, the drive motor 4061 is first started to drive the threaded rod body 403 to rotate. The threaded rod body 403 is threadedly connected to the first mounting block 402, and through the cooperation of the first sliding groove 404 and the first slider 405, the rotation of the threaded rod body 403 drives the first mounting block 402 and the fixing plate 5 to rise and fall on the outer wall of the threaded rod body 403. Thus, the height of the infrared temperature scanning camera 504 is adjusted by the rise and fall of the first mounting block 402 and the fixing plate 5, which facilitates the operator to inspect and maintain the infrared temperature scanning camera 504.

[0033] Example 3: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a dynamic steelmaking temperature monitoring device with integrated furnace gas analysis. It can realize the functions of most dynamic steelmaking temperature monitoring devices with integrated furnace gas analysis on the market. However, after long-term use, the infrared thermal imager is prone to failure, making it impossible to repair the infrared thermal imager, thereby increasing the labor intensity of the operator. At the same time, the existing infrared thermal imager is not convenient for the operator to move and fix, which causes inconvenience to the operator. The support and fixing mechanism 6 includes a positive and negative screw body 601. The positive and negative screw body 601 is rotatably installed inside the device frame 1 through bearings. The outer wall of the positive and negative screw body 601 is threadedly connected to a threaded sleeve 603, and the bottom end of the threaded sleeve 603 is hinged to a rotating rod 604. The bottom end of the rotating rod 604 is hinged to a second mounting block 606. A turntable body 602 is installed at one end of the positive and negative screw body 601.

[0034] The outer wall of the second mounting block 606 is provided with a base plate 605, and the interior of the base plate 605 is provided with a rectangular groove 6051. The second mounting block 606 and the rectangular groove 6051 cooperate with each other. The side walls on both sides of the interior of the rectangular groove 6051 are provided with second sliding grooves 6061, and the interior of the second sliding grooves 6061 is provided with a second slider 6062. The side wall of one side of the second slider 6062 is fixedly connected to the side wall of the second mounting block 606.

[0035] The specific working principle is as follows: when it is necessary to support and fix the device frame 1, firstly, the positive and negative screw body 601 is rotated, and the positive and negative screw body 601 is threadedly connected to the threaded sleeve 603, so that the positive and negative screw body 601 rotates to drive the two sets of threaded sleeves 603 to slide in opposite directions and drive the rotating rod 604 to rotate. Furthermore, through the cooperation of the second slide groove 6061 and the second slider 6062, the rotating rod 604 rotates to drive the second mounting block 606 to slide inside the second slide groove 6061 through the second slider 6062 and drive the base plate 605 to rise and fall. Thus, the device frame 1 is positioned and fixed by the rise and fall of the base plate 605, which facilitates the operation of the operator.
