Description

Technical Field

[0001] The utility model belongs to the technical field of infrared temperature measurement, in particular to an infrared temperature measurement structure used for an industrial furnace. Background Art

[0002] In industrial processing furnaces such as deposition furnaces, infiltration furnaces, carbonization furnaces, ink furnaces, cracking furnaces, siliconizing furnaces, sintering furnaces, and melt infiltration furnaces, the operating temperature will be between 0° and 3000°. For example, in vacuum furnaces, during the use of vacuum furnaces, it is necessary to use temperature measuring instruments to monitor the temperature in the furnace in order to achieve the purpose of controlling the temperature in the furnace to meet the product process requirements. When the measured temperature is higher than 2000°C, the commonly used temperature measurement method is to use a thermocouple + high-temperature infrared thermometer. Thermocouples are used to detect the temperature in the low-temperature section, and high-temperature infrared thermometers are used to detect the temperature in the high-temperature section. When the measured temperature is higher than the high-temperature section, the thermocouple exits the furnace body through a moving mechanism, and a high-temperature infrared thermometer is used to continue to detect the temperature in the furnace.

[0003] When this measurement method is used to measure temperature, the thermocouple is easily collided with the furnace body during the process of the thermocouple withdrawing from the furnace body, resulting in damage to the thermocouple, and the thermocouple cannot be measured for a long time. Damage to the thermocouple makes it impossible to accurately measure the temperature in the furnace.

[0004] The existing temperature measuring device uses high-temperature infrared to measure the temperature of the inner wall of the furnace body. It cannot accurately measure the temperature of the low-temperature furnace body wall, and it is impossible to clean the observation hole of the temperature measuring device in real time, which causes the operator to make mistakes in the reading of the infrared measuring instrument. Therefore, we designed an infrared temperature measurement structure for industrial furnaces. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] like Figure 1-7 As shown: an infrared temperature measurement structure for an industrial furnace, comprising a furnace body 1 with an observation hole and a low-temperature measurement component 2 and a high-temperature measurement component 3 installed on the observation hole, wherein the low-temperature measurement component 2 and the high-temperature measurement component 3 both include an observation hole seat 6, a cleaning mechanism and a fine-tuning rotation mechanism, wherein the observation hole seat 6 is installed on the observation hole and one end of the observation hole seat 6 is inserted into the furnace body 1, and a lens 7 is arranged on the top of the observation hole seat 6; the cleaning mechanism is arranged at the upper end of the observation hole seat 6 and is located below the lens 7; the fine-tuning rotation mechanism is arranged above the lens 7 and is fixedly connected to the observation hole seat 6; an infrared thermometer 12, the bottom of the infrared thermometer 12 is fixedly connected to the fine-tuning rotation mechanism; the lens 7 in the low-temperature measurement component 2 is a silicon crystal glass lens, and the infrared thermometer 12 in the low-temperature measurement component 2 is a low-temperature infrared thermometer; the lens 7 in the high-temperature measurement component 3 is a quartz glass lens, and the infrared thermometer 12 in the high-temperature measurement component 3 is a high-temperature infrared thermometer.

[0029] In this embodiment, a low temperature measurement component 2 and a high temperature measurement component 3 are installed in the furnace body 1. The low temperature measurement component 2 is mainly used for measuring low temperature environments, so a silicon crystal glass lens is used, which has good optical performance and stability in low temperature environments. In addition, the infrared thermometer 12 in the low temperature measurement component 2 is a low temperature infrared thermometer, which can perform accurate temperature measurement under low temperature conditions.

[0030] In contrast, the high temperature measurement component 3 is used for measuring in a high temperature environment, so a quartz glass lens is used. The quartz glass lens has high thermal stability and optical performance in a high temperature environment, and can meet the high temperature measurement requirements. The infrared thermometer 12 in the high temperature measurement component 3 is a high temperature infrared thermometer, which can achieve accurate temperature measurement under high temperature conditions.

[0031] In practical applications, according to the different temperatures in the industrial furnace, real-time monitoring of different temperature ranges can be achieved by switching the low-temperature measurement component 2 and the high-temperature measurement component 3. This design enables the infrared temperature measurement structure to have high measurement accuracy and a wide range of applications, which helps to improve the degree of automation and safety performance of the industrial production process. This temperature measurement method does not require a mobile temperature measurement device, avoids damage to the equipment caused by the mobile temperature measurement device, and solves the problem of high-temperature damage to thermocouples in the range of 800°C to 900°C.

[0032] In addition, the infrared temperature measurement structure also includes an observation hole seat 6, a cleaning mechanism and a fine-tuning rotating mechanism. The observation hole seat 6 is installed on the observation hole to ensure the stability and accuracy of the temperature measurement component. The cleaning mechanism is arranged at the upper end of the observation hole seat 6 and below the lens 7. It can regularly clean the dust and impurities on the surface of the lens to ensure the clarity of the lens, thereby improving the temperature measurement accuracy. The fine-tuning rotating mechanism is arranged above the lens 7 and is fixedly connected to the observation hole seat 6, which is convenient for fine-tuning the thermometer to achieve more accurate temperature measurement.

[0033] Through the above design, the infrared temperature measurement structure of this embodiment has high practical value in the field of industrial furnaces. It can not only realize real-time monitoring of the temperature in the furnace, but also switch the measurement of different temperature ranges according to actual conditions to meet the needs of different working conditions. At the same time, the setting of the cleaning mechanism and the fine-tuning rotating mechanism further ensures the temperature measurement accuracy and improves the stability and reliability of the entire infrared temperature measurement structure.

[0034] like Figure 4-7As shown: a connecting pipe 61 is arranged on one side of the top of the observation hole seat 6, and a cleaning mechanism is installed on the connecting pipe 61. The cleaning mechanism includes a rotating shaft 13 and a cleaning cantilever 15 installed at the end of the rotating shaft 13 and located at the observation hole seat 6. The rotating shaft 13 is inserted into the connecting pipe 61, and a fastening screw sleeve 14 is arranged on the outer sleeve of the rotating shaft 13. The fastening screw sleeve 14 is located between the rotating shaft 13 and the inner wall of the connecting pipe 61. A plurality of sealing rings 17 are also sleeved on the rotating shaft 13, and spacers 16 are arranged between the sealing rings 17. The sealing ring 17 is located on the front side of the fastening screw sleeve 14.

[0035] In this embodiment, the design of the cleaning mechanism is highly practical and innovative. The setting of the rotating shaft 13 allows the cleaning cantilever 15 to rotate flexibly, and the function of the fastening screw sleeve 14 is to fix the rotating shaft 13 to prevent it from sliding or shifting during use. In addition, the setting of the sealing ring 17 and the spacer 16 helps to prevent dust and impurities from entering the observation hole seat 6 and protect the internal parts of the equipment. During use, the cleaning mechanism is first connected to the observation hole seat 6 through the connecting pipe 61, and then the rotating shaft 13 is started to drive the cleaning cantilever 15 to rotate.

[0036] like Figure 3-5 As shown: a graphite sleeve 5 is installed at the bottom of the observation hole seat 6, and a graphite plug 4 is provided at the bottom end of the graphite sleeve 5.

[0037] In this embodiment, the main function of the graphite sleeve 5 is to protect the bottom of the observation hole seat 6 and prevent it from being damaged during use. The graphite plug 4 plays a sealing role to ensure that the pressure and temperature inside the observation hole are stable. The graphite sleeve 5 and the graphite plug 4 are made of graphite material, which is a material with high thermal conductivity, high tensile strength and good wear resistance. The excellent performance of graphite material under high temperature and high pressure environment makes the design of the observation hole seat 6 more reliable and safe.

[0039] In this embodiment, the infrared thermometer 12 is fine-tuned and rotated through the spherical movable fisheye 10, thereby realizing accurate temperature measurement of the target object. The spherical locking ring A9 and the spherical locking ring B11 play the role of stabilizing and fixing the spherical movable fisheye 10, ensuring that the infrared thermometer 12 can be stably aligned with the target object during the fine-tuning process. The pressure cover 8 plays the role of protecting the lens 7, preventing external impurities from entering the surface of the lens 7 and affecting the accuracy of temperature measurement.
