Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of coke oven temperature measurement, specifically to a coke oven wall temperature measurement device. Background Technology

[0002] In the coking process, the temperature of the coke oven wall is a key parameter for measuring the operating status of the coke oven, ensuring coke quality, and extending the service life of the coke oven. Accurately controlling the wall temperature helps to rationally regulate the coking process, ensure uniform coke maturation, and avoid problems such as decreased coke quality and increased energy consumption due to localized overheating or undercooling. However, traditional methods of measuring coke oven wall temperature have significant drawbacks.

[0003] Currently, most coke oven temperature measurement equipment is limited by the unique enclosed structure and high-temperature, highly corrosive environment of coke ovens, making it impossible to directly penetrate the oven walls for accurate temperature measurement. Operators often have to measure the surface temperature of the oven body or indirectly through openings such as oven doors and riser pipes, then extrapolate the internal temperature of the oven walls using empirical formulas. This indirect measurement method not only has large measurement errors but also fails to reflect the true temperature distribution inside the oven walls, easily leading to misjudgments of the coke oven's internal temperature. When localized temperature anomalies occur in the oven walls, they cannot be detected and adjusted in time, potentially causing damage to the oven wall bricks, unreasonable coking times, and other problems, severely impacting coke production and quality, and even threatening the safe operation of the coke oven. With the increasing demands for precision and intelligence in the coking industry, developing a device that can directly penetrate the coke oven to accurately measure the temperature of the oven walls has become an urgent need to solve the current temperature measurement challenges and improve coking production efficiency and quality. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a coke oven wall temperature measuring device, which solves the technical problem that most existing coke oven temperature measuring devices are limited by the special closed structure of the coke oven and the high temperature and strong corrosive environment, and cannot directly penetrate into the oven to accurately measure the temperature of the oven wall.

[0005] According to one aspect, at least one embodiment of this disclosure provides a coke oven wall temperature measuring device, comprising:

[0006] The system includes a pre-set base plate, an upright plate, and a main frame, with the upright plate mounted on the pre-set base plate and the main frame mounted on the upright plate.

[0007] A temperature measurement drive assembly is disposed between the main frame and the upright plate;

[0008] A supporting movable component is disposed between the preset base plate and the upright plate;

[0009] A closed protective assembly is disposed on the upright plate;

[0010] The driving temperature measurement component includes a long port, which is vertically opened on the side surface of the upright plate. The main frame is laterally slidably connected inside the long port. The main frame has an overall gate-shaped structure. Several temperature sensors are provided at the upper and lower ends of both sides of the main frame.

[0011] As a further technical solution, a through cavity is provided in the main frame, and a pair of guide rods are vertically arranged at one end of the through cavity. A lifting block is slidably connected to the guide rod. A spool driven by electricity is provided at both ends of one side of the main frame. A reel is provided at both ends of the upper end of the through cavity. A pair of high-temperature resistant cables are connected between the spool and the lifting block. The high-temperature resistant cables are laid on the reels.

[0012] As a further technical solution, an opening is provided on the side surface of the main frame located on one side of the guide rod, and a long frame is provided on the side end face of the lifting block. The long frame is movably connected to the long opening and the opening. A rotating shaft driven by electricity is provided inside the long frame, and several infrared thermometers are provided on the rotating shaft. The main frame is connected to the upright plate by a linear drive.

[0013] As a further technical solution, the enclosed protection assembly includes a pair of cylinders, which are fixed at both ends of the side surface of the upright plate. A pair of crossbars are provided on the other side surface of the upright plate, and an enclosed plate is movably fitted onto the crossbars. The output end of the cylinders is connected to the enclosed plate.

[0014] As a further technical solution, the supporting moving component includes several slide rails, all of which are disposed on the surface of the preset base plate, and a sliding bracket is disposed at the bottom of the upright plate, the sliding bracket being slidably connected to the slide rails.

[0015] As a further technical solution, the lower end of the sliding bracket has a three-pronged structure.

[0016] As a further technical solution, both the rotating shaft and the spool drive are located on the outside of the upright plate.

[0017] As a further technical solution, both opposite end faces of the pair of sealing plates are concave structures, and the concave portion of the side end face of the sealing plate matches the vertical length of the main frame.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the temperature measurement component is driven by sliding the main frame within the long opening, allowing the temperature sensor to be directly brought into the coke oven and in contact with the furnace wall for accurate temperature data collection. Simultaneously, the spool and lifting block work together to raise and lower the infrared thermometer, and the rotating shaft enables the infrared thermometer to scan at multiple angles. This achieves a combination of contact temperature measurement and infrared temperature measurement, covering different positions on the furnace wall. This solves the problem that traditional equipment cannot penetrate deep into the furnace for accurate temperature measurement, ensuring comprehensive and accurate furnace wall temperature information and providing a reliable basis for judging the coke oven's operating status and controlling the process.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-3 As shown, it illustrates a coke oven wall temperature measuring device according to an embodiment of the present disclosure, comprising:

[0032] The system includes a base plate 1, an upright plate 2, and a main frame 3. The upright plate 2 is mounted on the base plate 1, and the main frame 3 is mounted on the upright plate 2.

[0033] A driving temperature measuring component 4 is disposed between the main frame 3 and the upright plate 2;

[0034] A supporting movable component 6 is disposed between the preset base plate 1 and the upright plate 2;

[0035] Enclosed protective component 5, which is disposed on the upright plate 2;

[0036] The driving temperature measuring component 4 includes a long opening 4-1, which is vertically opened on the side surface of the upright plate 2. The main frame 3 is laterally slidably connected inside the long opening 4-1. The main frame 3 has an overall gate-shaped structure. Several temperature sensors 4-2 are provided at the upper and lower ends of both sides of the main frame 3. A through cavity 4-3 is opened inside the main frame 3. A pair of guide rods 4-4 are vertically arranged at one end of the through cavity 4-3. Lifting blocks 4-5 are slidably connected to the guide rods 4-4. A spool 4-6 driven by electricity is provided at both ends of one side of the main frame 3. A reel 4-7 is provided at both ends of the upper end of the through cavity 4-3. A pair of high-temperature resistant cables 4-8 are connected between the spool 4-6 and the lifting block 4-5. The high-temperature resistant cables 4-8 are laid on the reel 4-7. An opening 4-9 is opened on the side surface of the main frame 3 located on one side of the guide rod 4-4. A long frame 4-10 is provided on the side end face of the lifting block 4-5. The long frame 4-10 is movably connected to the long opening 4-1 and the opening 4-9. A rotating shaft 4-11 driven by electricity is provided inside the long frame 4-10. Several infrared thermometers 4-12 are provided on the rotating shaft 4-11. The main frame 3 is connected to the upright plate 2 by linear drive.

[0037] In some examples, the driven temperature measuring component 4 achieves precise temperature measurement of the coke oven wall through structural design. The main frame 3 is linearly driven and controlled to slide within the long opening 4-1 of the vertical plate 2, allowing it to be pushed as a whole to the coke oven opening for easy access into the oven. Temperature sensors 4-2 on both sides of the main frame 3 can directly contact the oven wall surface to collect temperature data in real time. Simultaneously, the spool 4-6 inside the cavity 4-3 rotates under electric drive, passing through the high-temperature resistant cable 4-8 and the reel 4-7, pulling the lifting block 4-5 up and down along the guide rod 4-4, thereby raising and lowering the long frame 4-10 connected to its outer side and the infrared thermometer 4-12 mounted on the rotating shaft 4-11. After the long frame 4-10 passes through the long opening 4-1 and the through opening 4-9 into the coke oven, the rotating shaft 4-11 rotates under electric drive, enabling the infrared thermometer 4-12 to scan the temperature of different locations on the oven wall from multiple angles and in all directions.

[0038] The combination of multiple temperature measurement methods not only ensures the accuracy of contact temperature measurement, but also expands the detection range through infrared temperature measurement, thereby comprehensively obtaining furnace wall temperature information.

[0039] like Figures 1-3 As shown in the figure, the enclosure protection component 5 proposed in this embodiment includes a pair of cylinders 5-1. The cylinders 5-1 are fixed at both ends of the side surface of the upright plate 2. A pair of crossbars 5-2 are provided on the other side surface of the upright plate 2. A sealing plate 5-3 is movably connected to the crossbars 5-2. The output end of the cylinders 5-1 is connected to the sealing plate 5-3.

[0040] In some examples, a sealing and protective assembly 5 is designed to effectively reduce the leakage of internal temperature from the coke oven. The sealing and protective assembly 5 includes cylinders 5-1 fixed to both ends of the side surface of the vertical plate 2, which can flexibly control the opening and closing of the sealing plate 5-3 according to temperature measurement requirements. When the temperature measuring assembly 4 is driven deep into the coke oven for temperature measurement, the output end of the cylinder 5-1 pushes the sealing plate 5-3 to slide along the crossbar 5-2, making it tightly fit against the oven opening and sealing most of the opening area. This significantly reduces the leakage of high-temperature gas from inside the coke oven, not only lowering the working environment temperature and ensuring operator safety, but also reducing heat loss, maintaining stable internal temperature of the coke oven, avoiding the impact of temperature fluctuations on measurement accuracy, and also contributing to energy conservation and improved coke oven operating efficiency.

[0041] like Figures 1-3 As shown in the figure, the supporting moving component 6 in this embodiment includes a plurality of slide rails 6-1, all of which are disposed on the surface of the preset base plate 1. A sliding bracket 6-2 is disposed at the bottom of the upright plate 2, and the sliding bracket 6-2 is slidably connected to the slide rails 6-1.

[0042] In some examples, to achieve flexible movement of the device and meet the needs of continuous temperature measurement in multiple areas, a supporting moving component 6 is designed. A slide rail 6-1 on the surface of the base plate 1 guides the sliding bracket 6-2 at the bottom of the upright plate 2. Operators can push the upright plate 2 or use an external drive device to smoothly slide the sliding bracket 6-2 along the slide rail 6-1. When temperature measurement of different coke oven walls is required, the device can quickly move to the corresponding position without disassembly and reassembly, significantly improving temperature measurement efficiency. Simultaneously, the stable sliding structure ensures the stability of the driving temperature measuring component 4 during movement, preventing measurement errors caused by shaking, and enabling the device to continuously and accurately detect the temperature of multiple coke oven walls.

[0043] For example, such as Figure 1 As shown, the lower end of the sliding bracket 6-2 has a three-pronged structure.

[0044] In some examples, the lower end of the sliding support 6-2 adopts a three-pronged structure, which significantly enhances the stability and flexibility of supporting the moving component 6. The three-pronged structure increases the contact area between the support and the slide rail 6-1, distributing the overall weight and force during device movement and preventing the device from tipping over or swaying due to a shift in the center of gravity. Even on uneven tracks, the three-pronged structure can ensure the smooth movement of the vertical plate 2 and the upper components through adaptive adjustment of the three support points. At the same time, this structural design makes the sliding support 6-2 slide more smoothly on the slide rail 6-1, reducing jamming and facilitating operators to quickly move the device between different furnace walls, efficiently completing continuous temperature measurement work.

[0045] For example, such as Figure 1 As shown, the rotating shaft 4-11 and the driving part of the spool 4-6 are both located on the outside of the vertical plate 2.

[0046] In some examples, the drive components for the rotating shaft 4-11 and the bobbin 4-6 are located on the outside of the vertical plate 2, optimizing the ease of operation and maintenance safety of the device. External placement of the drive components allows operators to visually observe the equipment's operating status and quickly perform equipment debugging and troubleshooting. Due to the high temperature and corrosive environment inside the coke oven, placing the drive components on the outside of the vertical plate 2 effectively prevents them from being affected by the harsh environment, extends the equipment's service life, and ensures the stable operation of the drive temperature sensing component 4.

[0047] For example, such as Figure 2 As shown, the two opposite end faces of the pair of sealing plates 5-3 are both concave structures, and the concave part of the side end face of the sealing plate 5-3 matches the vertical length of the main frame 3.

[0048] In some examples, the opposite end faces of a pair of sealing plates 5-3 have a concave structure, and the concave portion matches the vertical length of the main frame 3. When the main frame 3 is inserted into the coke oven for temperature measurement, the concave portion of the sealing plate 5-3 can tightly wrap around the side of the main frame 3, forming a complete sealed space around the main frame 3, minimizing the leakage of high-temperature gas from the coke oven through the gap between the main frame 3 and the sealing plate 5-3. At the same time, the concave structure does not obstruct the sliding and lifting of the main frame 3, ensuring the normal operation of the driving temperature measuring component 4. When the temperature measurement is completed and the main frame 3 is retracted, the sealing plate 5-3 closes to the maximum extent, further improving the sealing effect of the furnace opening, effectively maintaining the stability of the internal temperature of the coke oven, and reducing heat loss and environmental thermal pollution.

[0049] In practical use: The preset base plate 1 is fixed in a suitable position next to the coke oven. The upright plate 2 is installed on the slide rail 6-1 of the preset base plate 1 via the sliding bracket 6-2 at the bottom. The main frame 3 is laterally slidably connected to the long opening 4-1 on the side surface of the upright plate 2. During temperature measurement, the main frame 3 is pushed along the long opening 4-1 to the coke oven mouth by a linear drive device, so that the temperature sensors 4-2 on both sides of the main frame 3 come into contact with the furnace wall surface and collect temperature data in real time. At the same time, the spool 4-6 on one side of the main frame 3 is started. The spool 4-6 is electrically driven to rotate, and the high-temperature resistant cable 4-8 passes around the pulley 4-7 to pull the lifting block 4-5 to slide up and down along the guide rod 4-4. This causes the long frame 4-10 on the side of the lifting block 4-5 to rise and fall within the long opening 4-1 and the through opening 4-9. The rotating shaft 4-11 inside the long frame 4-10 is electrically driven to rotate, so that the infrared thermometer 4-12 scans different positions of the furnace wall from multiple angles. During temperature measurement, cylinders 5-1 at both ends of the side surface of the vertical plate 2 are activated. The output end of cylinder 5-1 pushes the sealing plate 5-3 to slide along the crossbar 5-2, so that the concave part of the sealing plate 5-3 tightly wraps the main frame 3 and seals the furnace opening. When it is necessary to measure the temperature of different coke oven walls, the vertical plate 2 is pushed, and the sliding bracket 6-2 moves smoothly to the corresponding position on the slide rail 6-1.
