Description

Technical Field

[0001] This invention relates to the field of high-temperature smelting temperature measurement technology, specifically to an infrared high-temperature smelting temperature measurement device. Background Technology

[0002] High-temperature smelting is a core process in modern metallurgical industry for extracting and refining metals. During the smelting process, raw materials such as ores and fluxes undergo complex physical phase transformations and chemical reactions at extremely high temperatures inside the smelting furnace, thereby separating the target molten metal and slag. This process is accompanied by intense energy exchange and material transformation, and requires extremely high stability of the process environment. It is a key stage to ensure the purity, mechanical properties, and overall production efficiency of the final metal product.

[0003] In the high-temperature smelting process, precise control of the furnace temperature is of paramount importance. Therefore, a high-temperature smelting temperature measuring device is required. If the temperature inside the smelting furnace is too low, it will lead to insufficient metal melting and incomplete chemical reaction, which will seriously affect the metal extraction rate. If the temperature is too high, it will not only cause huge energy waste, but also accelerate the damage to the internal refractory lining of the smelting furnace, and even lead to excessive burning of metal elements, thus reducing product quality.

[0004] Existing high-temperature smelting temperature measurement devices mostly employ infrared thermometry technology, including infrared temperature probes and front-end light-transmitting lenses. The working principle is that the probe receives infrared light radiated by the high-temperature molten metal inside the smelting furnace through the light-transmitting lens, and calculates and displays the current furnace temperature through photoelectric conversion. However, the environment inside a smelting furnace is extremely harsh, constantly accompanied by large amounts of high-temperature molten slag splashing and dense dust. Slag and dust can impact or adhere to the light-transmitting lens, causing damage or blocking the infrared light. To solve these problems, existing technologies typically add static protection in front of the light-transmitting lens. Long tubes or baffles are used to try to reduce the direct impact of debris through physical isolation. However, while static protective covers can block some of the larger debris flying in a straight line, they cannot prevent the spread of fine dust and angled splashes from entering and gradually adhering to the lens surface. Over time, this will still lead to a decrease in light transmittance. To clean it thoroughly, temperature measurement must be interrupted or even the furnace must be stopped for manual disassembly and wiping. This not only increases the difficulty of maintenance, but also prevents the temperature measuring device from continuously monitoring the temperature inside the high-temperature furnace, resulting in a decrease in temperature measurement accuracy and failing to meet the monitoring needs of modern smelting. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an infrared high-temperature smelting temperature measuring device, which solves the problems of existing temperature measuring devices having their light-transmitting lenses damaged by splashing molten slag in the furnace, and the stubborn dust and slag adhering to their surfaces being difficult to remove, resulting in the blocking of infrared light, the inability to perform continuous temperature measurement, and a decrease in measurement accuracy.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an infrared high-temperature smelting temperature measuring device, comprising a support column, a horizontal plate fixedly connected to the top of the support column, a sliding plate slidably connected to the bottom of the horizontal plate, a protective mechanism provided on the lower side of the sliding plate, an installation mechanism provided on the bottom right side of the sliding plate, and a moving mechanism provided on the inner side of the support column. The protective mechanism includes a housing, which is located on the lower right side of the sliding plate. An infrared temperature probe is fixedly connected to the bottom left side of the inner wall of the housing. A light-transmitting sheet is provided on the bottom right side of the housing. A servo motor is fixedly connected to the upper middle part of the left side of the inner wall of the housing. A transmission rod is fixedly connected to the output end of the servo motor. The right end of the transmission rod passes through the housing and is fixedly connected to a slag-blocking paddle. A cleaning component is provided on the inner side of the housing.

[0007] Preferably, the moving mechanism includes a threaded rod rotatably connected to the inner bottom of the support column, a movable column threadedly connected to the outer side of the threaded rod, the outer side of the movable column being slidably connected to the inner wall of the support column, a support frame fixedly connected to the top left side of the movable column, a connecting rod rotatably connected to the right side of the support frame, and the top of the connecting rod being rotatably connected to the bottom left end of the sliding plate.

[0008] Preferably, the cleaning assembly includes an eccentric wheel, which is fixedly connected to the outside of the transmission rod. Fixed rods are fixedly connected to the front and rear sides of the inside of the housing. A movable plate is slidably connected to the middle of the outer side of the fixed rod. A bracket is fixedly connected to the bottom of the movable plate. A sponge brush is fixedly connected to the outer side of the bracket through the housing and is in contact with the light-transmitting sheet.

[0009] Preferably, the protective mechanism further includes a spring, which is disposed on the lower side of the outer wall of the fixed rod, and the top of the spring abuts against the movable plate.

[0010] Preferably, the mounting mechanism further includes a movable ring, which is slidably connected to the outside of the lever. A second spring is fixedly connected to the front side of the movable ring, and the front end of the second spring abuts against the button.

[0011] Preferably, the mounting mechanism further includes a locking block, which is fixedly connected to the outside of the lever, and a locking groove is provided on the front side of the inner cavity, and the locking block engages with the locking groove.

[0012] Preferably, the moving mechanism further includes a driven bevel gear, which is fixedly connected to the outer bottom of the threaded rod. A rotating handle is fixedly connected to the front bottom of the support column, and the rear end of the rotating handle passes through the support column and is fixedly connected to a driving bevel gear.

[0013] Preferably, the moving mechanism further includes a rubber frame, which is fixedly connected to the top of the movable column, and the outer side of the rubber frame is in contact with the inner wall of the column.

[0014] Preferably, a base is fixedly connected to the bottom of the support column, and reinforcing plates are provided on the left and right sides of the top of the support column. The outer walls of the reinforcing plates are fixedly connected to the support column and the base by bolts on both sides.

[0015] This invention provides an infrared high-temperature smelting temperature measuring device. It has the following beneficial effects: 1. This invention uses a servo motor to drive a transmission rod to rotate, which in turn rotates a slag-blocking deflector to deflect splashing furnace slag inside the furnace, reducing its impact on the light-transmitting plate. Simultaneously, the transmission rod rotates, driving an eccentric wheel to move up and down, and then resets with the help of a spring. When the movable plate moves downwards, a sponge brush driven by a bracket scrapes away dust adhering to the outside of the light-transmitting plate. This allows for dynamic physical shielding of splashing slag and real-time cleaning of the light-transmitting plate while simultaneously measuring temperature, preventing damage to the plate or obstruction of infrared light by dust. This ensures the infrared temperature probe can continuously monitor the interior of the high-temperature furnace, improving measurement accuracy.

[0016] 2. This invention allows the locking block to disengage from the slot and compress the second spring by pressing and pulling the button. Simultaneously, the second wedge block moves to release the restriction on the first wedge block. Then, the positioning block can be moved to release the lock on the outer shell, enabling quick disassembly for maintenance of the internal equipment. During installation, pressing the button pushes the second wedge block through the lever. The wedge surface design of the second wedge block and the first wedge block pushes the back plate and positioning block downwards. The wedge surface at the bottom of the positioning block firmly presses the outer shell between the fixing frame and the stop block, facilitating regular inspection and maintenance of the internal equipment. It also ensures the device is securely installed in harsh environments and prevents loosening during temperature measurement.

[0017] 3. This invention drives the active bevel gear to rotate by rotating the handle. The meshing of the active and driven bevel gears drives the threaded rod to rotate, which in turn pushes the movable column to move upward inside the support column. When the movable column moves, it pushes the sliding plate to move horizontally to the right through the support frame and connecting rod, thereby driving the outer shell to go deeper into the high-temperature furnace and adjust the detection position of the infrared temperature measuring probe. The temperature measuring position can be flexibly adjusted according to the actual smelting liquid level and process requirements, which improves the operational stability and practicality of the temperature measuring device.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figure 2 , Figure 3 and Figure 4 This invention provides an infrared high-temperature smelting temperature measuring device, including a support column 1, a horizontal plate 5 fixedly connected to the top of the support column 1, a sliding plate 6 slidably connected to the bottom of the horizontal plate 5, a protective mechanism 2 provided on the lower side of the sliding plate 6, an installation mechanism 3 provided on the bottom right side of the sliding plate 6, and a moving mechanism 4 provided on the inner side of the support column 1. The protective mechanism 2 includes a housing 21, which is located on the lower right side of the sliding plate 6. An infrared temperature probe 22 is fixedly connected to the bottom left side of the inner wall of the housing 21. A light-transmitting sheet 23 is provided on the bottom right side of the housing 21 to prevent dust and impurities from contacting the infrared temperature probe 22. A servo motor 24 is fixedly connected to the upper middle part of the left side of the inner wall of the housing 21. A transmission rod 25 is fixedly connected to the output end of the servo motor 24. The right end of the transmission rod 25 passes through the housing 21 and is fixedly connected to a slag-blocking plate 26. The servo motor 24 can drive the slag-blocking plate 26 to rotate through the transmission rod 25. A cleaning assembly 27 is provided inside the housing 21. The cleaning assembly 27 includes an eccentric wheel 271, which is fixedly connected to... Connected to the outside of the transmission rod 25, the transmission rod 25 drives the eccentric wheel 271 to rotate. The front and rear sides of the inner shell 21 are fixedly connected to the fixed rod 272. The middle of the outer side of the fixed rod 272 is slidably connected to the movable plate 273. The bottom of the movable plate 273 is fixedly connected to the bracket 274. The outer side of the bracket 274 passes through the shell 21 and is fixedly connected to the sponge brush 275. The sponge brush 275 is in contact with the light-transmitting sheet 23. The movable plate 273 can drive the sponge brush 275 to rotate through the bracket 274. The protective mechanism 2 also includes a spring 276. The spring 276 is set on the lower side of the outer wall of the fixed rod 272. The top of the spring 276 abuts against the movable plate 273. The spring 276 can push the movable plate 273 to reset. Specifically, when using this temperature measuring device, the infrared temperature probe 22 emits infrared light. The infrared light penetrates the light-transmitting plate 23 at the bottom of the outer casing 21 and directly illuminates the interior of the high-temperature smelting furnace. The high-temperature material inside the furnace reflects the infrared light, which returns along the original path and passes through the light-transmitting plate 23 again. It is then captured by the receiving end of the infrared temperature probe 22 to complete the temperature measurement step. By starting the servo motor 24, the output shaft of the servo motor 24 drives the transmission rod 25 to rotate synchronously, thereby driving the slag-blocking plate 26 fixed on the outer end of the transmission rod 25 to move in the outer area of ​​the light-transmitting plate 23. The rotating plate 26 rotates in a circular motion, controlled by a servo motor 24. This rotation speed is synchronized with the infrared light emission and reception, ensuring the light passes precisely through the physical gap between adjacent plates 26. This prevents the physical plates from blocking the infrared light path. Simultaneously, the continuous circular motion of the plates 26 creates a dynamic protective surface directly in front of the light-transmitting plate 23. Molten slag splashed from the high-temperature furnace collides with the rotating plates 26 before approaching the light-transmitting plate 23, altering its trajectory. The impact of the slag being deflected reduces the probability of furnace slag directly striking the light-transmitting plate 23. Furthermore, the transmission rod 25 drives the eccentric wheel 271 to rotate eccentrically. When the protruding end of the eccentric wheel 271 rotates to the lower position, the outer edge of the eccentric wheel 271 presses against the movable plate 273, forcing the movable plate 273 to slide downwards. The movable plate 273 compresses the spring 276. When the eccentric wheel 271 passes its lowest point, the spring 276 pushes the movable plate 273 upwards to reset. During the downward movement of the movable plate 273, the sponge brush 275 below is driven by the bracket 274 connected to the bottom. As the light-transmitting plate 23 moves downward, the sponge brush 275, which is attached to the outer surface of the light-transmitting plate 23, can rub and scrape the outer side of the light-transmitting plate 23 to remove the attached dust. As the transmission rod 25 rotates continuously, the eccentric wheel 271 repeatedly lifts and releases the movable plate 273. With the cooperation of the spring 276, the sponge brush 275 reciprocates to clean the surface of the light-transmitting plate 23. The dynamic blocking of the slag-blocking plate 26 and the attachment and scraping of the sponge brush 275 prevent the infrared light transmission from being blocked due to dust accumulation or debris, thus ensuring measurement accuracy.

[0022] Reference Figure 5 , Figure 6 and Figure 7The installation mechanism 3 includes multiple fixing brackets 31, all of which are fixedly connected to the bottom right side of the sliding plate 6. A stop block 32 is fixedly connected to the bottom right side of the sliding plate 6. An inner cavity 313 is opened on the inner right side of the sliding plate 6. A back plate 33 is slidably connected to the bottom of the inner side of the inner cavity 313. A positioning block 34 is fixedly connected to the bottom of the back plate 33. The outer side of the positioning block 34 penetrates the sliding plate 6. A wedge-shaped surface 35 is opened on the bottom left side of the positioning block 34. A first wedge block 36 is fixedly connected to the top of the back plate 33. A lever 314 is provided on the right side of the front wall of the sliding plate 6. The rear side of the lever 314 penetrates the sliding plate 6 and is fixedly connected to a second wedge block 37. The lever 314 can move... The second movable wedge block 37 moves and contacts the first wedge block 36. The front end of the lever 314 is fixedly connected to the button 38. The mounting mechanism 3 also includes a movable ring 311, which is slidably connected to the outside of the lever 314. The front side of the movable ring 311 is fixedly connected to the second spring 312, and the front end of the second spring 312 abuts against the button 38. The mounting mechanism 3 also includes a locking block 39, which is fixedly connected to the outside of the lever 314. The front side of the inner cavity 313 is provided with a locking groove 310, and the locking block 39 engages with the locking groove 310. Through the engagement of the locking block 39 with the locking groove 310, the second wedge block 37 can be prevented from disengaging from contact with the first wedge block 36. Specifically, when the temperature measuring device needs to separate the outer casing 21 for internal equipment maintenance, pressing the button 38 inward will cause the lever 314 to move under pressure. Simultaneously, the button 38 will compress the second spring 312, causing it to contract. The lever 314 will also move the locking block 39, causing it to disengage from the slot 310 and releasing the slot 310 from its rotational constraint on the lever 314. At this point, rotating the button 38 ninety degrees will cause the lever 314 to simultaneously deflect the locking block 39 ninety degrees. Then, applying a pulling force outward will actuate the button 38. Pulling lever 314 moves locking block 39, aligning it with and passing through the slot on sliding plate 6. During this pulling process, the movement of lever 314 causes wedge block 2 37 at the tail end to slide synchronously. The displacement of wedge block 2 37 disengages from its contact with wedge block 1 36, releasing the downward pressure limiting effect of wedge block 2 37 on wedge block 1 36. Then, the positioning block 34 is pushed upward, causing the positioning block 34 to push the back plate 33 upward. The back plate 33 causes the top wedge block 1 36 to move upward synchronously. The upward retraction of positioning block 34 releases the limiting effect on the outer shell 21. At this point, the object placed on the fixing frame 3 can be placed... 1. The inner outer shell 21 is removed for maintenance. During installation, the outer shell 21 is placed inside the fixing frame 31. Pressing button 38 causes the button 38 to push the second wedge block 37 to move via lever 314. As the second wedge block 37 moves, the wedge surface guides it downward by the contact friction between the bottom inclined surface and the top inclined surface of the first wedge block 36, forcing the first wedge block 36 to push the back plate 33 to slide vertically downward. The back plate 33 moves downward, pushing the positioning block 34 through the bottom surface of the sliding plate 6, initially restricting the outer shell 21 inside the fixing frame 31. During the insertion of the positioning block 34, due to the positioning... A wedge-shaped surface 35 is machined on the bottom left side of block 34. When the wedge-shaped surface 35 extends downward, it fits against the edge of the outer shell 21 and generates a lateral squeezing force, which tightly squeezes the outer shell 21 between the fixing frame 31 and the stop block 32, making the outer shell 21 firmly fixed. After the position is fixed, the button 38 is rotated 90 degrees in the opposite direction again, which drives the locking block 39 to return to the initial position and align with the slot 310. At this time, the spring 312, which is in a compressed state, releases its elastic force to push the button 38, forcing the locking block 39 to re-insert and engage inside the slot 310. This engaging state prevents the locking block 39 from disengaging from the slot 310, thus avoiding loosening when the outer shell 21 is fixed.

[0023] Reference Figure 1 , Figure 8 and Figure 9The moving mechanism 4 includes a threaded rod 41, which is rotatably connected to the bottom inner side of the support column 1. A movable column 42 is threadedly connected to the outer side of the threaded rod 41. When the threaded rod 41 rotates, it drives the movable column 42 to move. The outer side of the movable column 42 is slidably connected to the inner wall of the support column 1. A support frame 43 is fixedly connected to the top left side of the movable column 42. A connecting rod 44 is rotatably connected to the right side of the support frame 43. The top of the connecting rod 44 is rotatably connected to the bottom left end of the sliding plate 6. The moving mechanism 4 also includes a driven bevel gear 45, which is fixedly connected to the bottom outer side of the threaded rod 41. A handle 46 is fixedly connected to the bottom front side of the support column 1. The rear end of the handle 46 passes through the support column 1 and is fixedly connected to a driving bevel gear 47. The moving mechanism 4 also includes a rubber frame 48, which is fixedly connected to the top of the movable column 42. The outer side of the rubber frame 48 contacts the inner wall of the support column 1. The rubber frame 48 can prevent dust or impurities from entering the gap between the movable column 42 and the support column 1. Specifically, when it is necessary to adjust the detection position of the infrared temperature probe 22, the handle 46 is rotated. When the handle 46 rotates, it drives the driving bevel gear 47 to rotate. Through the meshing transmission between the driven bevel gear 45 and the driving bevel gear 47, the threaded rod 41 is driven to rotate inside the support column 1. When the threaded rod 41 rotates, it drives the movable column 42 to move upward inside the support column 1. When the movable column 42 slides upward, it drives the top support frame 43 to move synchronously. Since the support frame 43 is connected to the sliding plate 6 through the connecting rod 44, when the support frame 43 moves, it moves through the top of the connecting rod 44 to the sliding plate. The bottom of the slide plate 6 generates a diagonal thrust, which pushes the slide plate 6 to the right. The rightward movement of the slide plate 6 directly drives the outer shell 21 to penetrate deeper into the high-temperature furnace, thereby completing the adjustment of the temperature measuring position of the outer shell 21. During the movement of the movable column 42, the rubber frame 48 installed on the top of the movable column 42 is tightly attached to the inner wall of the support column 1 to form a blocking layer. When the movable column 42 moves up and down to adjust its position, the rubber frame 48 can intercept residue falling into the mechanical fit gap between the support column 1 and the movable column 42, preventing the transmission mechanism from jamming and improving the practicality of the temperature measuring device under complex working conditions.

[0024] Reference Figure 1 The bottom of the support column 1 is fixedly connected to the base 7, and the top left and right sides of the support column 1 are provided with reinforcing plates 8. The outer walls of the reinforcing plates 8 are fixedly connected to the support column 1 and the base 7 respectively by bolts 9. Specifically, the reinforcing plate 8 can be fixed to the support column 1 and the base 7 by bolt 9, making the support column 1 more secure.

[0025] Working principle: When using the temperature measuring device, the infrared temperature probe 22 emits infrared light, which passes through the light-transmitting plate 23 and shines into the high-temperature smelting furnace. The reflected light is then received by the infrared temperature probe 22, allowing it to measure the temperature within the furnace. During the measurement process, the servo motor 24 drives the transmission rod 25 to rotate, which in turn rotates the slag-blocking plates 26. The servo motor 24 controls the rotation speed of the slag-blocking plates 26, ensuring that the infrared light passes through the gaps between the multiple slag-blocking plates 26 during measurement, preventing the light from being blocked. Furthermore, the rotating slag-blocking plates 26 deflect splashed molten slag from the furnace, reducing the impact of molten slag on the light-transmitting plate 23. Simultaneously, when the transmission rod 25 rotates, it also drives the eccentric wheel 271 to rotate. When the eccentric wheel 271 rotates, it pushes the movable plate 273 to move downward, thereby compressing the spring 276. When the movable plate 273 moves downward, it drives the sponge brush 275 to move downward through the bracket 274. When the sponge brush 275 moves, it can scrape off the dust attached to the outside of the light-transmitting plate 23, preventing the light-transmitting plate 23 from being blocked by dust and preventing infrared light from being emitted. The spring 276 pushes the movable plate 273 to move, so that when the eccentric wheel 271 moves to the highest point, the movable plate 273 can be reset. The slag-blocking plate 26 spreads out the furnace slag and the sponge brush 275 cleans the light-transmitting plate 23, so that the infrared temperature measuring probe 22 can continuously detect the temperature inside the high-temperature furnace, improving the measurement accuracy. Furthermore, when it is necessary to disassemble the outer casing 21 for maintenance of the internal equipment, first press button 38. Button 38 will move lever 314, and button 38 will compress spring 312. Lever 314 will then move locking block 39, disengaging locking block 39 from locking slot 310, thus releasing the limiting effect on lever 314. At this time, rotate button 38 ninety degrees, and button 38 will rotate locking block 39 ninety degrees. Then pull button 3... 8. Button 38 will pull lever 314 to move, causing block 39 to pass through the slot on sliding plate 6. As lever 314 moves, it will also move wedge block 2 37, causing it to disengage from wedge block 1 36, thus releasing the limiting effect on wedge block 1 36. Then, positioning block 34 will be pushed upwards, causing wedge block 1 36 to move upwards via back plate 33, thereby releasing the limiting effect on outer casing 21. This allows the device placed on a fixed surface to be placed... The outer shell 21 inside the fixed frame 31 can be disassembled for easy maintenance of the internal components. During installation, pressing button 38 will move wedge block 37 via lever 314. The wedge-shaped design of the contact surface between wedge block 37 and wedge block 36 allows wedge block 36 to push the back plate 33 downwards, enabling the positioning block 34 to pass through the sliding plate 6. This locks the outer shell 21 inside the fixed frame 31. The positioning block 34 is inserted... When the positioning block 34 is inserted, due to the wedge-shaped surface 35 on the bottom left side, the positioning block 34 can press the outer shell 21 between the fixing frame 31 and the stop block 32 when it moves downward, so that the outer shell 21 can be firmly fixed. After the fixing is completed, the button 38 is rotated ninety degrees, which causes the locking block 39 to engage with the locking groove 310. The spring 312 will apply a pushing force to the button 38, so that the locking block 39 will not disengage from the locking groove 310, thus preventing the outer shell 21 from becoming loose when it is fixed. Finally, when it is necessary to adjust the detection position of the infrared temperature probe 22, rotate the handle 46. When the handle 46 rotates, it will drive the active bevel gear 47 to rotate. Since the driven bevel gear 45 meshes with the active bevel gear 47, when the active bevel gear 47 rotates, the driven bevel gear 45 will drive the threaded rod 41 to rotate, thereby pushing the movable column 42 to move upward inside the support column 1. The movable column 42 will then drive the support frame 43 to move. Since the support frame 43 is connected to the sliding plate 6 through the connecting rod 44, when the support frame 43 moves upward, it can push the sliding plate 6 to move to the right through the connecting rod 44, thereby driving the outer shell 21 to go deeper into the high-temperature furnace, thereby adjusting the temperature measurement position of the outer shell 21. Furthermore, the rubber frame 48 at the top of the movable column 42 can prevent residue from falling into the gap between the support column 1 and the movable column 42, improving the practicality of the temperature measuring device.
