Description

Technical Field

[0001] The invention relates to the field of metal material production, and more specifically to a temperature measuring device for a smelting furnace. Background Art

[0002] Melting furnaces are used to produce high-temperature alloys, precision alloys and other materials, and are widely used in science and technology and production. As material performance requirements become higher and higher, the temperature needs to be monitored and controlled during the smelting process.

[0003] At present, the temperature measurement devices used in smelting furnaces are mainly non-contact temperature measurement and contact temperature measurement. The contact temperature measurement couple is easily damaged in the high-temperature and highly corrosive smelting environment, and the maintenance cost is high. The response speed of contact measurement is relatively slow. At the same time, the measurement process may have a physical impact on the measured object. For example, the temperature distribution of a high-temperature object may change due to the contact of the sensor. Non-contact temperature measurement does not require contact with the target object. It is particularly suitable for measuring high-temperature, dangerous or moving objects, such as temperature measurement in a smelting furnace, and is therefore widely used.

[0004] However, when non-contact temperature measurement is used to measure the temperature of the object being measured inside the melting furnace through the glass window, the combustion and heating process in the melting furnace will produce a large amount of smoke, gas and tiny solid particles. These substances will move through the airflow in the furnace and deposit on the glass surface to form a covering. The smoke and gas deposition will form an opaque or translucent pollution layer, which changes the ability of infrared rays to penetrate the glass, resulting in the inability of the infrared thermometer to accurately measure the temperature in the furnace. The glass window needs to be cleaned manually regularly, which is troublesome. Summary of the invention

[0037] The clamping part 4 includes a hydraulic rod 41 fixedly connected to the upper end of the top plate 36 and a cover body 42 connected to the upper end of the protective glass 232, and the telescopic end of the hydraulic rod 41 passes through the top plate 36 and is fixedly connected to the upper end of the cover body 42.

[0039] By adopting the above technical solution, when the side of the protective glass 232 facing the smelting furnace 1 is contaminated, the hydraulic rod 1 41 is controlled to work and contract to drive the cover body 42 to move upward. When the cover body 42 moves upward inside the shell 31 and separates from the upper end of the protective glass 232, the motor 2 37 works to drive the screw rod 1 34 to rotate. The rotation of the screw rod 1 34 drives the hollow ring body 231 to move upward, so that the hollow ring body 231 is moved out of the groove 21. When the gear 2 38 outside the hollow ring body 231 contacts the gear 1 33, the motor 1 32 works to drive the gear 1 33 and the gear 2 38 to rotate. The gear 2 38 rotates to drive the protective glass 232 to rotate inside the hollow ring body 231. When the protective glass 232 rotates 180°, the flipping is completed. The protective glass 232 is moved to face the cover body 42 with the contaminated side thereof, and the motor 237 is operated to drive the hollow ring body 231 to reset, so that the hollow ring body 231 and the turned-over protective glass 232 enter the groove 21 again, and the sealing gasket 233 on one side of the protective glass 232 enters the sealing groove 22. The hydraulic rod 1 41 is operated to drive the cover body 42 to move downward, and the lower end of the cover body 42 is pressed on the upper end of the protective glass 232 to press the protective glass 232 tightly in the groove 21. After the contaminated side of the protective glass 232 is cleaned by the glass cleaning part 6, the hydraulic rod 2 51 is operated to drive the infrared thermometer 52 to descend, so that the temperature measuring end of the infrared thermometer 52 is attached to the upper end of the protective glass 232, and the temperature of the object to be measured in the smelting furnace 1 is measured.

[0040] like Figure 5 - Figure 7 As shown, the glass cleaning unit 6 includes a support plate 61 fixedly connected to the inner wall of the cover body 42, a rotary joint 62 fixedly connected to the upper end of the support plate 61, a pump body 64 fixedly connected to the upper end of the support plate 61, and a liquid storage tank 65, and the inner tube of the rotary joint 62 passes through the support plate 61 and is fixedly connected to a hollow rod body 66, a frame plate 67 is fixedly connected to the outer surface of the hollow rod body 66, and a cleaning unit 68 is connected to the frame plate 67, a nozzle 69 connected to the hollow rod body 66 is connected to one side of the frame plate 67, and a driving component 63 for driving the hollow rod body 66 to rotate is also connected to the frame plate 67, the output end of the pump body 64 is connected to the input end of the rotary joint 62, and the input end of the pump body 64 is connected to the output end of the liquid storage tank 65. A sponge 7 is also fixedly connected to the inside of the frame 67, and the lower end of the sponge 7 extends out from the frame 67 to absorb the liquid on one side of the protective glass 232. An electric heating element for drying the sponge 7 is connected to the inside of the frame 67, and a plurality of through holes 8 for discharging the gas generated during drying are opened at the upper end of the frame 67.

[0041] The driving assembly 63 includes a motor 3 631 fixedly connected to the upper end of the support plate 61 , a gear 3 632 rotatably connected to the lower end of the support plate 61 , and a gear 4 633 fixedly connected to the outer surface of the hollow rod body 66 and meshing with the gear 3 632 .

[0042] The cleaning part 68 includes an outer rod body 681 rotatably connected to the inner wall of the frame plate 67, a flange 423 integrally formed on the outer surface of the outer rod body 681, and a brush 683 movably sleeved on the outer rod body 681 and the outside of the flange 423, and one end of the outer rod body 681 extends outward through the frame plate 67 and is fixedly connected to a gear five 682, and an active cavity 421 is opened on the inner wall of the cover body 42, and a tooth key 422 meshing with the gear five 682 is integrally formed on the inner wall of the active cavity 421.

[0043] By adopting the above technical solution, the motor three 631 works to drive the gear three 632 to rotate, the gear three 632 rotates to drive the gear four 633 and the hollow rod body 66 to rotate, the hollow rod body 66 rotates to drive the frame plate 67 to rotate, the pump body 64 can pump the cleaning liquid in the liquid storage tank 65 from the rotary joint 62 into the hollow rod body 66, and enter the nozzle 69 from the hollow rod body 66, the nozzle 69 sprays the cleaning liquid on the contaminated side of the protective glass 232, when the frame plate 67 rotates, the gear five 682 connected to one side of the frame plate 67 can move in the movable cavity 421, when the gear five 682 contacts the tooth key 422, the tooth key 422 drives the gear five 682 and the outer rod body 681 to rotate, the outer rod body 681 rotates to drive the brush 683 to rotate in the frame plate 67, the brush 683 rotates to contact the protective glass 232 The contaminated side is cleaned, and the sponge 7 can clean the liquid and impurities on the protective glass 232 after cleaning to prevent impurities and liquid from remaining on one side of the protective glass 232. The liquid is absorbed into the sponge 7, and the sponge 7 is heated by the electric heating element inside the frame 67 to dry the moisture in the sponge 7. Part of the impurities after cleaning will adhere to the outer surface of the sponge 7, and the other part will remain on one side of the protective glass 232 and be scraped by the sponge 7 to form a line on the protective glass 232. When the sponge 7 is replaced regularly, the impurities remaining on the protective glass 232 can be cleaned. Since the residual impurities are gathered on one side of the sponge 7, when the infrared thermometer 52 is attached to one side of the protective glass 232, the residual impurities will not affect the normal temperature measurement of the infrared thermometer 52.

[0044] like Figure 7 and Figure 8As shown, a movable groove 684 and a slot 686 connected to the movable groove 684 are also provided inside the outer rod body 681, and an inner rod body 687 is movably connected inside the movable groove 684, a spring 685 is also provided inside the movable groove 684, and two ends of the spring 685 are respectively connected to one end of the inner rod body 687 and the inner wall of the movable groove 684, one end of the inner rod body 687 passes through the outer rod body 681 and the gear five 682 and extends outward, and the extended end of the inner rod body 687 is rotatably connected to a ball 688, a flange 423 for pushing the inner rod body 687 to move in the movable groove 684 is fixedly connected to the inner wall of the movable cavity 421, and an extension strip is integrally formed on the outer surface of the inner rod body 687, and the extension strip passes through the slot 686 and is fixedly connected to the inner wall of the brush 683.

[0045] By adopting the above technical solution, when the gear 5 682 rotates in the movable cavity 421, the flange 423 can push the ball 688 and the inner rod 687 to move in the direction of the spring 685 when it contacts the ball 688. The spring 685 is compressed. When the flange 423 separates from the ball 688, the spring 685 can push the inner rod 687 to move in the direction of the ball 688 in the outer rod 681, so that the inner rod 687 moves laterally inside the outer rod 681. In this way, the brush 683 can rotate with the outer rod 681 and can also move on the outer rod 681. The body 681 moves laterally on the outside (the movement of the inner rod body 687 drives the brush 683 to move). By combining rotation and lateral movement, it can effectively reduce cleaning dead angles and ensure that each part can be fully cleaned. Since the lateral movement can increase the cleaning range and reduce the need for multiple cleanings, it can clean a larger area of ​​the glass surface more quickly. Especially when the pollution is unevenly distributed, the lateral moving brush 683 can adjust the cleaning route so that pollutants in different positions can be removed, especially for stubborn deposits and stains, thereby improving the cleaning efficiency.

[0046] like Figure 6 and Fig. 9 As shown, a polishing and mark removal part 9 is also connected to one side of the frame plate 67, and the polishing and mark removal part 9 includes two fixed blocks 91 symmetrically fixed on one side of the frame plate 67, a screw rod 93 rotatably connected between the two fixed blocks 91, a moving seat 94 screwed to the outside of the screw rod 93 and slidably connected to one side of the frame plate 67, a motor 95 fixed to the upper end of the moving seat 94, a polishing wheel 96 rotatably connected to the lower end of the moving seat 94 and connected to the output shaft of the motor 95, and a motor 92 fixed to one side of one of the fixed blocks 91, and the output shaft of the motor 92 is fixed to one end of the screw rod 93.

[0047] By adopting the above technical solution, the motor 5 95 drives the polishing wheel 96 to rotate, and the polishing wheel 96 can polish the cleaned protective glass 232, further eliminate the fine scratches or cleaning marks that may still exist on the glass surface, restore the smoothness and transparency of the glass, thereby improving the transmittance of infrared rays, ensuring the accuracy of the thermometer, and preventing the long-term accumulation of pollutants on the glass surface from corroding the material, while removing the minor damage caused by the pollutant cleaning process, extending the service life of the protective glass 232, and the polished glass surface is smoother, which can reduce the adhesion of pollutants. Smooth surfaces are often less likely to absorb pollutants such as dust and smoke than rough surfaces, reducing the accumulation frequency of pollutants, thereby reducing the frequency of cleaning, and the motor 4 92 drives the screw 2 93 to rotate, and the rotation of the screw 2 93 can drive the moving seat 94 to move, thereby adjusting the position of the polishing wheel 96, and polishing different positions on the protective glass 232.

[0048] like Fig.10 As shown, two through slots 10 are symmetrically provided inside the cover body 2, and two L-shaped extensions 11 are symmetrically fixedly connected to the lower end of the cover body 2, the two L-shaped extensions 11 are respectively connected to the two through slots 10, and an air curtain machine 12 and an exhaust fan 13 are respectively fixedly connected to the two L-shaped extensions 11, a filter screen 16 is fixedly connected to the inner wall of one of the through slots 10, and the opening of the other through slot 10 is connected to the pipe 14, and a purifier 15 connected to the other end of the pipe 14 is fixedly connected to the upper end of the cover body 2.

[0049] By adopting the above technical solution, the air curtain machine 12 (mature existing technology, no further description here) generates a high-speed airflow, which blows toward the exhaust fan 13 to form a protective door, and by generating a layer of high-speed airflow in front of the protective glass 232, pollutants are blown away or blocked from the glass surface, forming an "air barrier". This air barrier can effectively isolate pollutants such as smoke, particulate matter, and volatile compounds generated in the furnace from the glass, reduce the possibility of their deposition on the glass surface, and effectively reduce the frequency of cleaning the protective glass 232. The exhaust fan 13 discharges the high-speed airflow into the pipeline 14, and the airflow and the gas in the smelting furnace 1 enter the purifier 15 from the pipeline 14 and are discharged after purification.

[0050] Instructions for use: When the side of the protective glass 232 facing the smelting furnace 1 is contaminated, the hydraulic rod 1 41 is controlled to work and contract to drive the cover body 42 to move upward. When the cover body 42 moves upward inside the shell 31 and separates from the upper end of the protective glass 232, the motor 2 37 works to drive the screw rod 1 34 to rotate. The rotation of the screw rod 1 34 drives the hollow ring body 231 to move upward, so that the hollow ring body 231 is moved out of the groove 21. When the gear 2 38 outside the hollow ring body 231 contacts the gear 1 33, the motor 1 32 works to drive the gear 1 33 and the gear 2 38 to rotate. The gear 238 rotates to drive the protective glass 232 to rotate inside the hollow ring body 231. After the protective glass 232 rotates 180°, the flipping action is completed.
