Abstract
Description
Technical Field
[0001] This utility model relates to the field of furnace wall temperature measurement technology, specifically to a non-contact furnace wall temperature measurement device. Background Technology
[0002] A non-contact furnace wall temperature measuring device is an instrument specifically designed to measure the surface temperature of the walls or linings of rotary kilns. Its core function is to acquire real-time temperature data of the furnace wall using non-contact temperature measurement technology and infrared radiation, without direct contact with the high-temperature furnace wall. This provides crucial information for equipment safety, process optimization, and energy efficiency management in industrial production.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] Conventional contact-based temperature measurement methods such as thermocouples and resistance temperature detectors cannot detect the temperature of the rotary kiln cylinder body; they can only detect the flue gas temperature and estimate the furnace wall temperature, which is detrimental to the safe operation of the equipment. Utility Model Content
[0005] The purpose of this invention is to provide a non-contact furnace wall temperature measuring device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-contact furnace wall temperature measuring device, comprising an outdoor combustion chamber, a flange installed on one side of the outdoor combustion chamber, a fixing bolt installed on one side of the flange, an infrared temperature sensor provided on one side of the fixing bolt, a conduit connected to one side of the infrared temperature sensor, a purge branch pipe installed at the upper end of the conduit, and an air inlet provided at the upper end of the infrared temperature sensor.
[0007] One side of the conduit is provided with an insulation layer, one side of the insulation layer is provided with a heating chamber, and one side of the heating chamber is provided with the main body of the rotary kiln.
[0008] The beneficial effects of this utility model are as follows: by adding an infrared temperature sensor and a purge branch pipe, when side temperature needs to be measured, the infrared temperature sensor uses infrared light to achieve temperature detection without the need for contact detection. At the same time, the purge branch pipe takes in air through the air inlet to purge the surface of the duct by spraying air. This also prevents the infrared temperature sensor from directly contacting the high-temperature flue gas, which would affect the stability of the detection.
[0009] To achieve the purging of the infrared temperature sensor:
[0010] Further configuration: The air inlet is connected to the purge branch pipe via an air pipe.
[0011] By adopting the above technical solution, when the equipment is being tested, the purging branch pipe is purged by air intake through the air inlet, which sprays air onto the surface of the duct. At the same time, it prevents the infrared temperature sensor from coming into direct contact with the high-temperature flue gas.
[0012] To maintain the internal temperature:
[0013] Further configuration: the central axis of the insulation layer coincides with the transverse central axis of the rotary kiln cylinder body.
[0014] By adopting the above technical solution, when high-temperature flue gas passes through the heating chamber, the insulation layer can isolate the internal and external temperatures, thereby reducing the temperature conduction rate and keeping the internal temperature warm.
[0015] To achieve heating of the main body of the rotary kiln:
[0016] Further configuration: the central axis of the heating chamber coincides with the transverse central axis of the insulation layer, and the interior of the heating chamber is hollow.
[0017] By adopting the above technical solution, when the equipment is working, high-temperature flue gas flows through the heating chamber and exchanges heat with the main body of the rotary kiln to heat the material inside the kiln.
[0018] To achieve temperature measurement of the rotary kiln casing:
[0019] Further configuration: the central axis of the infrared temperature sensor coincides with the transverse central axis of the conduit.
[0020] By adopting the above technical solution, when it is necessary to measure the temperature of the main body of the rotary kiln, the infrared temperature sensor can obtain the corresponding temperature by utilizing the principle that different temperatures and different materials emit infrared rays of different wavelengths.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0027] Please see Figures 1 to 3 A non-contact furnace wall temperature measuring device includes an outdoor combustion chamber 1, a flange 2 installed on one side of the outdoor combustion chamber 1, a fixing bolt 3 installed on one side of the flange 2, an infrared temperature sensor 4 provided on one side of the fixing bolt 3, a conduit 5 connected to one side of the infrared temperature sensor 4, a purge branch pipe 6 installed at the upper end of the conduit 5, and an air inlet 7 provided at the upper end of the infrared temperature sensor 4.
[0028] A heat insulation layer 8 is provided on one side of the conduit 5, a heating chamber 9 is provided on one side of the heat insulation layer 8, and a rotary kiln cylinder body 10 is provided on one side of the heating chamber 9.
[0029] In this embodiment, as Figure 1 As shown, the air inlet 7 is connected to the purge branch pipe 6 via an air pipe.
[0030] In this embodiment, as Figure 2 As shown, the central axis of the insulation layer 8 coincides with the transverse central axis of the rotary kiln cylinder body 10.
[0031] In this embodiment, as Figure 2 As shown, the central axis of the heating chamber 9 coincides with the transverse central axis of the insulation layer 8, and the interior of the heating chamber 9 is hollow.
[0032] In this embodiment, as Figure 2 and Figure 3 As shown, the central axis of the infrared temperature sensor 4 coincides with the transverse central axis of the conduit 5.
[0033] The computer software involved in the hardware carriers such as the infrared temperature sensor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.
[0034] Therefore, the "infrared temperature sensor" and the like involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the non-contact furnace wall temperature measuring device of this application, so as to solve the corresponding technical problems to be solved by this application.
[0035] The non-contact furnace wall temperature measuring device operates as follows:
[0036] First, high-temperature flue gas flows through the heating chamber 9 and exchanges heat with the rotary kiln body 10 to heat the material inside the kiln. When it is necessary to measure the temperature of the rotary kiln body 10, the infrared temperature sensor 4 (model: IT-545) can obtain the corresponding temperature by utilizing the principle that different temperatures and materials emit infrared rays of different wavelengths. At the same time, when the infrared temperature sensor 4 is measuring the temperature, the purging branch pipe 6 introduces air through the air inlet 7 to purge the surface of the duct 5. This also prevents the infrared temperature sensor 4 from directly contacting the high-temperature flue gas and avoids water vapor in the flue gas from condensing on the probe of the infrared temperature sensor 4, which would affect the accuracy of the detection.
