[0028] As mentioned in the background section above, during the glass furnace production process, it is necessary to monitor the temperature inside the glass furnace in real time using temperature sensors. However, since the temperature sensors are inserted into the glass furnace, they are susceptible to corrosion from the high-temperature gases inside, potentially leading to damage. Therefore, the inventors of this application provide a large arch structure and a glass furnace in one or more embodiments. The large arch structure has blind holes and through holes. A first temperature sensor is placed in the blind hole to monitor the temperature inside the glass furnace, thus preventing direct contact between the high-temperature gases inside the furnace and the first temperature sensor, which could then corrode and damage it. A second temperature sensor placed in the through hole corrects the temperature readings from the first sensor, ensuring the accuracy of temperature monitoring in the glass furnace. This solves one or more problems in the prior art.
[0029] To address the aforementioned technical problems, this utility model provides a large arch structure for a glass furnace, such as... Figure 1 As shown, it includes: a body 1; a blind hole 2, which is opened on the body 1 and is used to place a first temperature sensor to monitor the temperature inside the glass furnace; and a through hole 3, which is also opened on the body 1 and is located at a distance from the blind hole 2, and is used to place a second temperature sensor to correct the monitoring result of the first temperature sensor, or to seal the through hole 3 with refractory material.
[0030] Specifically, a blind hole 2 is formed on the main body 1, and a first temperature sensor is inserted into the blind hole 2 to monitor the temperature inside the glass furnace. Since the blind hole 2 is not connected to the inside of the glass furnace, the high-temperature gas inside the glass furnace will not corrode the first temperature sensor, thus ensuring the service life of the first temperature sensor. However, this will also cause the temperature value measured by the first temperature sensor to deviate from the actual temperature inside the glass furnace (below average). Therefore, a second temperature sensor needs to be inserted into the through hole 3, and the temperature value measured by the second temperature sensor is used to correct the temperature value measured by the first temperature sensor. In some embodiments, the first temperature sensor can be placed in the blind hole for temperature detection for a long time, while the second temperature sensor can be placed through the through hole for a predetermined time (e.g., several hours). This ensures that the second temperature sensor is not corroded by the high-temperature gas inside the glass furnace for a long time, while correcting the temperature measured by the first temperature sensor, and also ensures the long-term durability of the first temperature sensor.
[0031] Example:
[0032] Step 1: Obtain the correction value △T
[0033] T represents the temperature value measured by the first temperature sensor, and t represents the temperature value measured by the second temperature sensor. Over a continuous period of 12 hours, the first temperature sensor measured the temperature at N time points, with the measured data being T1, T2, ..., Tn. Simultaneously, the second temperature sensor also measured the temperature at N time points, with the measured data being t1, t2, ..., tn. After 12 hours, the second temperature sensor was pulled out of the through hole 3, and the through hole 3 was sealed with refractory material. The correction value ΔT = [(t1-T1) + (t2-T2) + ... + ((tn-Tn))] / n.
[0034] Step 2: Temperature monitoring of the glass furnace
[0035] Ts is the temperature of the glass furnace.
[0036] Ts = T + △T.
[0037] Compared with the prior art, the large arch structure of the glass furnace in this application has blind holes 2 and through holes 3 on the main body 1. A first temperature sensor is placed in the blind hole 2 to monitor the temperature inside the glass furnace, while avoiding the problem of the high-temperature gas inside the glass furnace directly contacting the first temperature sensor and corroding and damaging it. The temperature value measured by the first sensor is corrected by a second temperature sensor placed in the through hole 3, thus ensuring the accuracy of temperature monitoring of the glass furnace.
[0038] In some embodiments, the bottom thickness of the blind hole 2 is no more than 3 cm. The bottom of the blind hole 2 serves to isolate the first temperature sensor from the internal space of the glass furnace, thereby preventing the high-temperature gases in the glass furnace from corroding the first temperature sensor. However, if the bottom thickness of the blind hole 2 is too large, it will also affect the accuracy of the temperature monitored by the first temperature sensor. Therefore, preferably, the bottom thickness of the blind hole 2 is set to 3 cm.
[0039] In some embodiments, the distance between the blind hole 2 and the through hole 3 is no greater than 10 cm. The closer the blind hole 2 and the through hole 3 are, the closer the temperature field conditions they are in, and the more accurate the correction of the temperature data measured by the second temperature sensor to the measurement data of the first temperature sensor will be. However, if the distance between them is too close, it will affect the structural strength of the body 1. Therefore, preferably, the distance between the blind hole 2 and the through hole 3 is set to 10 cm.
[0040] In some embodiments, such as Figure 2As shown, there are multiple blind holes 2. Specifically, multiple blind holes 2 are evenly arranged on the body 1, and a first temperature sensor is installed in each blind hole 2, so that the temperature field of the entire glass furnace can be monitored in real time. Specifically, without affecting the structure of the body 1, a through hole 3 is opened in conjunction with each blind hole 2 to correct the monitoring results.
[0041] In some embodiments, the refractory material includes refractory cotton. After obtaining the correction value ΔT, the second temperature sensor is pulled out of the through hole 3, and the through hole 3 is blocked with refractory cotton to avoid the influence of the through hole 3 on the temperature field inside the glass furnace. Refractory cotton has advantages such as high temperature resistance and good heat insulation performance, and is also easy to operate.
[0042] In some embodiments, such as Figure 2 As shown, the main body 1 includes a structural layer 4 and an insulation layer 5. The insulation layer 5 covers the structural layer 4, and the opening end of the blind hole 2 is located on the insulation layer 5, with its bottom located inside the structural layer 4. The structural layer 4 encloses the internal space of the glass furnace, ensuring the process requirements and safety of glass processing. The insulation layer 5 prevents heat loss from the glass furnace, thus avoiding any impact on the quality of glass processing.
[0043] In some embodiments, structural layer 4 includes corundum. Corundum has advantages such as high hardness, wear resistance, high melting point, and corrosion resistance, which ensure the processing quality of glass furnaces and product quality, while also extending the service life of glass furnaces.
[0044] In some embodiments, the insulation layer 5 comprises multiple layers. The multiple layers of insulation layer 5 ensure its insulation effect and prevent heat loss from the glass, thus avoiding production disruptions.
[0045] This utility model also provides a glass furnace, including a first temperature sensor and the aforementioned glass furnace arch structure.
[0046] In some embodiments, the first temperature sensor includes a thermocouple. Thermocouples offer advantages such as high measurement accuracy, wide temperature range, simple operation, fast response, small size, and good stability, ensuring accurate temperature monitoring of the glass furnace. The second temperature sensor can be a thermocouple of the same specifications and brand as the first temperature sensor.
[0047] In summary, compared with the prior art, this disclosure provides a large arch structure for a glass furnace and a glass furnace. The main body 1 of the large arch structure has blind holes 2 and through holes 3. A first temperature sensor is placed in the blind hole 2 to monitor the temperature inside the glass furnace, while avoiding the problem of high-temperature gas inside the glass furnace directly contacting the first temperature sensor and corroding and damaging it. The temperature value measured by the first sensor is corrected by a second temperature sensor placed in the through hole 3, ensuring the accuracy of temperature monitoring of the glass furnace.
