[0002] The crucible furnace exhaust system is a key auxiliary system integrated into the crucible furnace system, designed to safely and efficiently capture, transport, and treat harmful fumes, high-temperature gases, and odors generated during the smelting process. Its core function is not to participate in the combustion process inside the furnace, but rather to serve as an important industrial environmental protection and occupational health and safety barrier, ensuring that the production environment meets environmental standards and protecting the health of operators.

[0003] In the existing technology, the crucible furnace usually uses an exhaust structure when it is in operation. According to the content of Chinese utility model patent with patent publication number CN218723214U, the wind hood in the exhaust structure generally requires the staff to clean the dust and other impurities on its inner wall, which is time-consuming and laborious, and the cleaning efficiency and effect are low, so it is in urgent need of improvement.

[0004] To address the aforementioned technical shortcomings, a solution is proposed that enables rapid cleaning of the crucible furnace exhaust structure, with lower difficulty in cleaning the inner wall, significantly improving the cleaning efficiency and effectiveness of the exhaust structure. Utility Model Content

[0005] The purpose of this invention is to provide an exhaust structure for a crucible furnace to solve the aforementioned problems.

[0006] The purpose of this utility model can be achieved through the following technical solution: an exhaust structure for a crucible furnace, including an exhaust hood body, a vertical exhaust pipe fixedly connected to the upper end of the exhaust hood body, a horizontal exhaust pipe fixedly connected to the top of the vertical exhaust pipe, an installation baffle plate provided at the top of the vertical exhaust pipe, a drive motor fixedly installed on the upper side of the installation baffle plate, an output shaft of the drive motor connected to an active shaft rod passing through the installation baffle plate, four sets of first connecting rods fixedly connected to the active shaft rod, a vertical scraper rod fixedly connected to the other end of the first connecting rod, and an inclined scraper rod fixedly connected to the bottom end of the vertical scraper rod; A main bevel gear is securely fitted to the outside of the drive shaft near the top. A driven shaft is located in the middle of the interior of the horizontal exhaust duct. Four sets of second connecting rods are fixedly connected to the driven shaft. A horizontal scraper is fixedly connected to the other end of the second connecting rod. A driven bevel gear is securely fitted to the end of the driven shaft.

[0007] Preferably, two sets of first fastening bolts are provided through the top of the vertical air duct, and two sets of first threaded grooves are provided on the outer side of the mounting baffle. The first fastening bolts pass through the vertical air duct and are threadedly connected to the mounting baffle through the first threaded grooves.

[0008] Preferably, one end of the horizontal air duct is provided with a perforated plate, and the driven shaft is rotatably connected to the perforated plate.

[0009] Preferably, the end of the horizontal air duct is provided with two sets of second fastening bolts, and the outer side of the perforated plate is provided with two sets of second threaded grooves, and the second fastening bolts pass through the horizontal air duct and are threadedly connected to the perforated plate in conjunction with the second threaded grooves.

[0012] Preferably, the main bevel gear meshes with the driven bevel gear, and all four sets of inclined scrapers are in contact with the inner wall of the wind shroud body.

[0013] The beneficial effects of this utility model are: (1) By starting the drive motor on the upper side of the mounting plate, the active shaft is rotated, which in turn drives the first connecting rod, the vertical scraper and the inclined scraper to rotate around the active shaft until the dust on the inner wall of the vertical air duct and the inner wall of the air hood is scraped off. At the same time, the rotation of the active shaft will drive the main bevel gear to rotate, and the main bevel gear meshes with the driven bevel gear, which will drive the driven shaft to rotate, and then drive the second connecting rod and the horizontal scraper to rotate around the driven shaft until the dust on the inner wall of the horizontal air duct is scraped off. This achieves the function of quickly cleaning the exhaust structure of the crucible furnace. The inner wall is easier to clean, which significantly improves the cleaning efficiency and effect of the exhaust structure. (2) First, under the cooperation of the second thread groove, reverse the screw of the second fastening bolt until the two sets of second fastening bolts are removed. At this time, the perforated plate and the driven shaft can be taken out from the end of the horizontal air duct. Then, under the cooperation of the first thread groove, rotate the first fastening bolt in the opposite direction until the two sets of first fastening bolts are removed. At this time, the mounting plate can slide down along the vertical air duct until the drive shaft is taken out from the inside of the vertical air duct.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: The application background of this utility model is based on the process of conveying harmful fumes in a crucible furnace. This process usually requires the use of an exhaust structure. The technical solution of this utility model is to solve the problem that the hood component in the existing exhaust structure generally requires workers to clean the dust and other impurities on its inner wall, which is time-consuming, labor-intensive, and has low cleaning efficiency and effect. Please see Figures 1-4 As shown, this embodiment is an exhaust structure for a crucible furnace, including a wind hood body 1. A vertical air duct 2 is fixedly connected to the upper end of the wind hood body 1. A horizontal air duct 3 is fixedly connected to the top of the vertical air duct 2. A mounting baffle 4 is provided at the top of the vertical air duct 2. A drive motor 5 is fixedly installed on the upper side of the mounting baffle 4. The output shaft of the drive motor 5 is connected to an active shaft rod 6 that passes through the mounting baffle 4. Four sets of first connecting rods 7 are fixedly connected to the active shaft rod 6. A vertical scraper rod 8 is fixedly connected to the other end of the first connecting rod 7. An inclined scraper rod 9 is fixedly connected to the bottom end of the vertical scraper rod 8. A main bevel gear 10 is fixedly sleeved on the outer side of the active shaft rod 6 near the top. A driven shaft rod 11 is provided in the middle of the interior of the horizontal air duct 3. Four sets of second connecting rods 12 are fixedly connected to the driven shaft rod 11. A horizontal scraper rod 13 is fixedly connected to the other end of the second connecting rod 12. A driven bevel gear 14 is fixedly connected to the end of the driven shaft rod 11. Four sets of first connecting rods 7 are evenly distributed on the outside of the drive shaft rod 6, and four sets of vertical scraper rods 8 are all in contact with the inner wall of the vertical air duct 2. The vertical scraper rods 8 on the first connecting rods 7 are used to scrape off the dust on the inner wall of the vertical air duct 2. Four sets of second connecting rods 12 are evenly distributed on the outside of the driven shaft rod 11, and four sets of horizontal scraper rods 13 are all in contact with the inner wall of the horizontal exhaust duct 3. The horizontal scraper rods 13 on the second connecting rods 12 are used to scrape off the dust on the inner wall of the horizontal exhaust duct 3. The main bevel gear 10 meshes with the driven bevel gear 14, and the four sets of inclined scraper rods 9 are all in contact with the inner wall of the wind shroud body 1. The meshing main bevel gear 10 and driven bevel gear 14 enable the rotation of the drive shaft 6 to drive the driven shaft 11 to rotate. Specifically, by activating the drive motor 5 on the upper side of the mounting plate 4, the drive shaft 6 is rotated, which in turn causes the first connecting rod 7, the vertical scraper 8, and the inclined scraper 9 to rotate around the drive shaft 6 until the dust on the inner wall of the vertical exhaust duct 2 and the inner wall of the hood body 1 is scraped off. At the same time, the rotation of the drive shaft 6 will drive the main bevel gear 10 to rotate, and the main bevel gear 10 meshes with the driven bevel gear 14, which in turn drives the driven shaft 11 to rotate, which in turn drives the second connecting rod 12 and the horizontal scraper 13 to rotate around the driven shaft 11 until the dust on the inner wall of the horizontal exhaust duct 3 is scraped off. This achieves a rapid cleaning function for the crucible furnace exhaust structure, with a lower difficulty in cleaning the inner wall, significantly improving the cleaning efficiency and effect of the exhaust structure.

[0018] Example 2: Please refer to Figures 1-4 As shown, this embodiment is an exhaust structure for a crucible furnace. Two sets of first fastening bolts 15 are provided through the top of the vertical exhaust duct 2. Two sets of first threaded grooves 16 are provided on the outer side of the mounting baffle 4. The first fastening bolts 15 pass through the vertical exhaust duct 2 and are threadedly connected to the mounting baffle 4 with the first threaded grooves 16. The mounting baffle 4 is fastened to the end of the vertical exhaust duct 2 by the cooperation of the first fastening bolts 15 and the first threaded grooves 16. One end of the horizontal air duct 3 is provided with a perforated plate 19. The driven shaft 11 is rotatably connected to the perforated plate 19. Two sets of second fastening bolts 17 are provided through the end of the horizontal air duct 3. Two sets of second threaded grooves 18 are opened on the outer side of the perforated plate 19. The second fastening bolts 17 pass through the horizontal air duct 3 and are threadedly connected to the perforated plate 19 with the second threaded grooves 18. The perforated plate 19 is fastened to the end of the horizontal air duct 3 by the cooperation of the second fastening bolts 17 and the second threaded grooves 18. Specifically, the second fastening bolt 17 is first screwed in the opposite direction with the cooperation of the second threaded groove 18 until both sets of the second fastening bolts 17 are removed. At this time, the perforated plate 19 and the driven shaft 11 can be taken out from the end of the horizontal air duct 3. Then, the first fastening bolt 15 is rotated in the opposite direction with the cooperation of the first threaded groove 16 until both sets of the first fastening bolts 15 are removed. At this time, the mounting plate 4 can slide down along the vertical air duct 2 until the drive shaft 6 is taken out from the inside of the vertical air duct 2. This realizes the step-by-step disassembly function of the cleaning structure of the air hood assembly, so as to replace and repair its parts.

[0019] As can be seen from Embodiments 1 and 2, by activating the drive motor 5 on the upper side of the mounting plate 4, the drive shaft 6 is rotated, thereby causing the first connecting rod 7, the vertical scraper 8, and the inclined scraper 9 to rotate around the drive shaft 6 until the dust on the inner wall of the vertical exhaust duct 2 and the inner wall of the hood body 1 is scraped off. At the same time, the rotation of the drive shaft 6 will drive the main bevel gear 10 to rotate, and the main bevel gear 10 meshes with the driven bevel gear 14, thereby driving the driven shaft 11 to rotate, which in turn drives the second connecting rod 12 and the horizontal scraper 13 to rotate around the driven shaft 11 until the dust on the inner wall of the horizontal exhaust duct 3 is scraped off. This achieves a rapid cleaning function for the crucible furnace exhaust structure, with lower difficulty in cleaning the inner wall, and significantly improves the cleaning efficiency and effect of the exhaust structure.

[0020] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
