Description

Technical Field

[0001] This utility model relates to the field of metallurgy, specifically to a monitoring device for the phenomenon of sparking during industrial silicon smelting. Background Technology

[0002] The phenomenon of flame bursting in industrial silicon smelting refers to the sudden burst of flames inside the furnace during the smelting process, usually accompanied by high temperature and intense light. This phenomenon not only threatens the safety of smelting equipment but may also cause injury to operators. The main causes include excessively high impurity content or uneven particle size of the raw materials, excessively fast feeding speed, unstable furnace temperature control, inappropriate electrode insertion depth, electrode breakage, and furnace lining damage. In order to facilitate the monitoring of raw materials inside the furnace, a corresponding smelting furnace flame bursting camera is usually installed at the point closest to the furnace wall along the center line of the flame in the furnace.

[0003] Currently, the monitoring device used for sparking phenomena in industrial silicon smelting typically consists of a high-temperature resistant camera located at the center line of the furnace flame closest to the furnace wall and a tripod supporting the camera. This high-temperature resistant camera usually has its own cooling circulation structure to ensure normal operation even at high temperatures. To prevent dust or sparks from hitting the lens, multiple air-cooling pipes are usually installed in front of the lens to cool it down while ensuring that furnace ash does not obstruct the lens.

[0004] During the observation process, although the air-cooled pipes can effectively blow away the furnace ash from the blast furnace lens, some furnace water inevitably splashes onto the lens when blast furnace liquid splashes. To ensure the safety of the lens, a detachable protective lens is installed in front of it. However, once the lens is splashed by furnace water, it will block the lens and affect the lens's shooting. In this case, the only way to continue shooting is to remove the high-temperature resistant camera from the furnace and replace the detachable protective lens. However, the act of removing and placing the high-temperature resistant camera from the furnace during the furnace opening is extremely dangerous, and the lens can usually only be repaired after the smelting is finished. Utility Model Content

[0005] The technical problem this invention aims to solve is that current monitoring devices for sparking phenomena in industrial silicon smelting cannot automatically replace the detachable protective lens of the high-temperature resistant camera inside the furnace.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a monitoring device for the phenomenon of sparking in industrial silicon smelting, including a furnace-mounted high-temperature resistant camera located at the center line of the furnace flame closest to the furnace wall and a tripod for fixing the furnace-mounted high-temperature resistant camera. Several air-cooling pipes are provided in front of the lens of the furnace-mounted high-temperature resistant camera, and a detachable protective lens that passes through the side wall of the furnace-mounted high-temperature resistant camera is provided in front of the lens.

[0007] The detachable protective lens is made of crystal silicon, and the left and right sides of the high-temperature resistant camera in the furnace are respectively provided with original lens storage components and waste lens storage components for storing new detachable protective lenses. The original lens storage components and waste lens storage components are each composed of a single open shell fixed to the side of the high-temperature resistant camera in the furnace by screws, a hollow column welded inside the single open shell, a T-shaped pressure rod passing through the opening end of the hollow column, and a pressure spring located inside the T-shaped pressure rod and the hollow column. The opening end of the hollow column is provided with a threaded cover to seal the hollow column, and the thin column end of the hollow column passes through the threaded cover.

[0008] The original lens storage assembly has several pneumatic telescopic rods passing through one side of the bottom surface of the single-opening shell, and the output end of the pneumatic telescopic rod is against the side of the uppermost detachable protective lens. The cavity sidewall of the single-opening shell and the side through groove of the high-temperature resistant camera in the furnace are located on the same plane.

[0009] As an improvement, the top surface of the thin column end of the T-shaped pressure bar is provided with a graphite packing gasket to prevent damage to the removable protective lens.

[0010] As an improvement, the left and right sides of the detachable protective lens are both curved.

[0011] As an improvement, a fixing plate for fixing a pneumatic telescopic rod is welded to the bottom surface of the single-opening shell, and the pneumatic telescopic rod is connected to the fixing plate by a bolt structure.

[0012] As an improvement, the output rod of the pneumatic telescopic rod is made of ceramic.

[0013] As an improvement, both the air-cooled pipe and the pneumatic telescopic rod are connected to the air pump via metal pipes.

[0014] The advantages of this invention compared to existing technologies are as follows: This device designs the detachable protective lens to be made of crystalline silicon, which ensures that even if the detachable protective lens breaks and falls into the furnace water, it will not affect the composition of the silicon furnace water. Original lens storage components and waste lens storage components are installed on both sides of the high-temperature resistant camera inside the furnace. By pushing the pneumatic telescopic rod, the new detachable protective lens will push the detachable protective lens in front of the high-temperature resistant camera inside the furnace into the single-opening shell of the waste lens storage component. After that, the pneumatic telescopic rod resets, and the next new detachable protective lens will be automatically pushed to the front under the action of the pressure spring, completing the lens loading and replacement.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] As per the instruction manual Figure 1 , 2 As shown, the system includes a furnace-mounted high-temperature resistant camera 1 located at the center line of the furnace flame closest to the furnace wall, and a tripod 2 for fixing the furnace-mounted high-temperature resistant camera 1. The tripod 2 can maximize the stability of the furnace-mounted high-temperature resistant camera 1. For easy disassembly, the tripod 2 is fixed inside the smelting furnace with screws. To reduce the impact of furnace dust on the lens, several air-cooling pipes 11 are provided in front of the lens of the furnace-mounted high-temperature resistant camera 1. To prevent splashing liquid from damaging the lens due to flame splattering, a detachable protective lens 3 is provided in front of the lens of the furnace-mounted high-temperature resistant camera 1, passing through the side wall of the furnace-mounted high-temperature resistant camera 1. To prevent the detachable protective lens 3 from cracking and affecting the purity of the furnace water, the detachable protective lens 3 is made of crystalline silicon.

[0023] As per the instruction manual Figure 2 , 3As shown in Figures 4 and 5, in order to ensure that the detachable protective lens 3 can be automatically replaced, the left and right sides of the high-temperature resistant camera 1 in the furnace are respectively provided with a new lens storage assembly 4 and a waste lens storage assembly 5 for storing new detachable protective lenses 3. The original lens storage assembly 4 and the waste lens storage assembly 5 have the same general structure. The original lens storage assembly 4 and the waste lens storage assembly 5 are both composed of a single open shell 41 fixed to the side of the high-temperature resistant camera 1 in the furnace by screws, a hollow column 42 welded inside the single open shell 41, a T-shaped pressure rod 43 passing through the opening end of the hollow column 42, and a pressure spring 44 located inside the T-shaped pressure rod 43 and the hollow column 42. The automatic loading and replenishment of the detachable protective lens 3 is completed by the pushing of the pressure spring 44, and it can be ensured that when the detachable protective lens 3 is replenished, the top detachable protective lens 3 is always aligned with the side slot of the high-temperature resistant camera 1 in the furnace, thereby ensuring the normal replacement of the detachable protective lens 3.

[0024] To prevent the T-shaped pressure rod 43 from detaching from the hollow column 42, the open end of the hollow column 42 is provided with a threaded cap 45 to seal the hollow column 42, and the thin end of the hollow column 42 passes through the threaded cap 45. The threaded cap 45 restricts the displacement length of the thick end of the T-shaped pressure rod 43, preventing the T-shaped pressure rod 43 from popping out of the hollow column 42. The cavity structure of the hollow column 42 is T-shaped, which matches the diameter of the pressure spring 44 and the thick end of the T-shaped pressure rod 43.

[0025] To prevent the T-shaped pressure bar 43 from damaging the removable protective lens 3, a graphite packing gasket 47 is provided on the top surface of the thin column end of the T-shaped pressure bar 43 to prevent damage to the removable protective lens 3. The graphite packing gasket 47 not only has high temperature resistance, but also good corrosion resistance and self-lubrication, making it perform well in high temperature, high pressure and harsh media environments.

[0026] In order to complete the automatic replacement of the detachable protective lens 3, the bottom side of the single-opening housing 41 of the original lens storage assembly 4 is provided with several pneumatic telescopic rods 46 that pass through the single-opening housing 41, and the output end of the pneumatic telescopic rods 46 is against the side of the uppermost detachable protective lens 3.

[0027] To facilitate the fixing of the pneumatic telescopic rod 46, a fixing plate 411 for fixing the pneumatic telescopic rod 46 is welded to the bottom surface of the single-opening shell 41, and the pneumatic telescopic rod 46 is connected to the fixing plate 411 by a bolt structure.

[0028] To prevent the output rod of the pneumatic telescopic rod 46 from scratching the detachable protective lens 3, the output rod of the pneumatic telescopic rod 46 is made of ceramic material, which ensures that the pneumatic telescopic rod 46 is resistant to high temperature and also ensures the smoothness of the output rod of the pneumatic telescopic rod 46.

[0029] To ensure that the detachable protective lens 3 will not be misaligned during translation, the cavity sidewall of the single-opening housing 41 is on the same plane as the side through groove of the high-temperature resistant camera 1 inside the furnace. In order to prevent the damaged detachable protective lens 3 from being pushed down more smoothly when it enters the single-opening housing 41 of the waste lens storage assembly 5, the left and right sides of the detachable protective lens 3 are both arc-shaped structures.

[0030] To ensure that the high-pressure cooling gas from the pneumatic pump can be smoothly transmitted to the air-cooled pipe 11 and the pneumatic telescopic rod 46, both the air-cooled pipe 11 and the pneumatic telescopic rod 46 are connected to the pneumatic pump through metal pipes.

[0031] In a specific implementation of this invention, when the detachable protective lens 3 in front of the lens is damaged by splashing molten metal, the high-temperature resistant camera 1 inside the furnace will send a corresponding damage signal. This signal will then drive the pneumatic telescopic rod 46 to push the damaged detachable protective lens 3 into the single-opening housing 41 on the other side. As the damaged detachable protective lens 3 enters the other single-opening housing 41, it will compress the graphite packing pad 47. During this compression, the graphite packing pad 47 will deform and slide down, causing the damaged detachable protective lens 3 to slide above the T-shaped pressure rod 43. After the pneumatic telescopic rod 46 finishes pushing, its output rod automatically resets, and the new detachable protective lens 3 in the original lens storage assembly 4 will automatically fill the gap under the action of the pressure spring 44 for the next replacement.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
