Description

Technical Field

[0001] This utility model relates to temperature measuring devices, and more particularly to a thermal imaging temperature measuring device for pellet rotary kilns. Background Technology

[0002] Industrial thermal imaging analysis systems are an important component of industrial kiln automation. With the rapid development of industrial manufacturing technology in my country, the efficient, energy-saving, and safe operation of industrial kilns has become particularly important. The widespread use of thermal imaging analysis technology has significantly improved the production efficiency of industrial enterprises and the safety and service life of equipment.

[0003] Traditional temperature measuring devices use a lead screw and nut structure to fix the lens. However, the repeated mechanical movement between the lead screw and nut can cause the lead screw to bend or the internal thread of the nut to be damaged. Furthermore, under the extreme temperature conditions of the kiln, the lead screw is more likely to deform and jam, affecting the fixation of the lens and the accuracy of temperature measurement. Utility Model Content

[0004] In order to overcome the shortcomings of traditional temperature measuring devices, such as the repeated mechanical movement of the lead screw and nut structure and its tendency to deform and jam under extreme kiln temperatures, which leads to unstable lens fixation and inaccurate temperature measurement, this utility model can provide an industrial thermal imaging temperature measuring device for pellet rotary kilns.

[0005] Technical solution: A thermal imaging temperature measurement device for pellet rotary kilns, comprising a thermal imager housing, 安 The system includes a mounting plate, air duct, protective cover, cylinder, lens, display screen, and control cabinet. The thermal imager housing has a mounting plate on the left end, housing the thermal imager itself. The thermal imager is externally connected to the control cabinet, which has a display screen on top. A protective cover is fitted inside the mounting plate, housing a pressure sensor. An air duct is located on the right end of the protective cover, housing a cylinder. A lens is located on the left end of the cylinder's extension rod, and the lens is electrically connected to the thermal imager. The thermal imager, display screen, cylinder, and pressure sensor are all electrically connected to the control cabinet.

[0006] Furthermore, the lens is designed as a pinhole lens.

[0007] Furthermore, it also includes a spiral plate, with a spiral plate installed inside the protective cover, and a purge air inlet at the right end of the air duct, which is connected to a first air source.

[0008] Furthermore, it also includes an alarm device, which is installed on the control cabinet and is electrically connected to the control cabinet.

[0009] Furthermore, it also includes a vortex refrigeration pipe, with a cooling air outlet and a cooling air inlet on the left and right sides of the bottom of the duct, respectively. A vortex refrigeration pipe is connected between the cooling air outlet and the cooling air inlet, and a second air source is connected to the cooling air inlet.

[0010] Furthermore, the outer shell, air duct, and protective cover of the thermal imager are all made of special high-temperature resistant stainless steel.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a cylinder to drive the lens to move, which simplifies the mechanical structure. The cylinder moves more smoothly and is less susceptible to deformation or jamming due to high temperature. When the pressure sensor detects insufficient cooling compressed air pressure or the thermal imager detects excessive lens temperature, the cylinder can be controlled by the control cabinet to retract the lens and push it out of the kiln to prevent lens damage.

[0012] 2. The spiral plate structure design inside the protective cover of this utility model accelerates the rotation of gas inside the protective cover to form a spiral air curtain in front of the lens. This not only improves the cooling effect and effectively protects the lens and thermal imager at high temperatures, but also increases the strength and blowing area of ​​the air curtain, effectively preventing dust in the kiln from contacting the lens, thus achieving a better dust-proof effect.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] A thermal imaging temperature measurement device for pellet rotary kilns, such as Figures 1-4 As shown, it includes a thermal imager housing 1, 安装板2. The thermal imager housing 1 has a mounting plate 2 on its left side, housing 1 housing the thermal imager housing housing 1 housing the thermal imager housing housing housing 1 housing the thermal imager housing housing 1 housing the thermal imager housing housing housing 1 housing the thermal imager housing housing housing 1 housing the thermal imager housing housing housing housing 1 housing the thermal imager housing housing housing housing 12 housing the thermal imager housing ...

[0020] like Figure 3 As shown, it also includes a spiral plate 14. The protective cover 7 is equipped with a spiral plate 14. The right end of the air duct 4 has a purge air inlet 3. The purge air inlet 3 is connected to a first air source. The first air source blows air into the purge air inlet 3, sending the airflow to the front end of the lens 10. The spiral plate 14 makes the airflow form a spiral air curtain in front of the lens 10, increasing the strength of the air curtain and the purge area, effectively preventing the dust in the kiln from contacting the lens objective, and achieving a better dust-proof effect.

[0021] like Figure 4 As shown, it also includes an alarm 13. The control cabinet 12 is equipped with an alarm 13, which is electrically connected to the control cabinet 12. The temperature threshold is set through the control cabinet 12. When the thermal imager detects that the temperature has reached the preset value, the control cabinet 12 retracts the cylinder 9 and activates the alarm 13. The alarm 13 issues an alarm to notify the operator that there is an abnormal high temperature, which improves the safety and reliability of the system.

[0022] like Figure 3 As shown, it also includes a vortex cooling pipe 8. Cooling air outlets 6 and cooling air inlets 5 are respectively opened on the left and right sides of the bottom of the air duct 4. The vortex cooling pipe 8 is connected between the cooling air outlets 6 and cooling air inlets 5. The cooling air inlet 5 is connected to a second air source. The second air source blows air into the vortex cooling pipe 8 from the cooling air inlet 5. The structure inside the vortex cooling pipe 8 causes the gas to move in a spiral motion. During this process, the gas is expanded, and the gas absorbs heat from the surrounding environment during the expansion process, which leads to a decrease in temperature, thereby reducing the temperature inside the air duct 4.

[0023] The thermal imager housing 1 is externally connected to the moving part of the electric guide rail. When the electric guide rail is activated, the device is extended into the kiln. The lens 10 will capture the infrared radiation of the kiln's internal surface and convert it into electrical signals. These signals will be processed by the thermal imager into a visualized thermal image, showing the temperature distribution of different parts, the melting of materials, and the shape of flames, etc., and will be displayed on the display screen 11 through the control cabinet 12. When the pressure sensor detects insufficient cooling compressed gas pressure or the thermal imager detects that the lens 10 temperature is too high, the cylinder 9 can be controlled through the control cabinet 12 to retract the lens 10 and push it out of the kiln, ensuring the safety of the lens 10.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
