Description

Technical Field

[0001] This utility model relates to the technical field of furnace flue gas dust collection hoods, specifically a flue gas dust collection hood for aluminum furnaces that facilitates material feeding. Background Technology

[0002] In the aluminum processing industry, aluminum furnaces are the core equipment for smelting aluminum and aluminum alloys. During operation, the high-temperature reaction between aluminum and auxiliary materials generates flue gas containing various pollutants such as dust, fluorides, sulfides, and metal oxides. Direct emission of this flue gas will not only seriously harm the respiratory system of workshop operators but also pollute the surrounding atmosphere.

[0003] Currently, the industry generally uses flue gas dust collection hoods as the core device for collecting flue gas from aluminum furnaces. The conventional design involves fixing the dust collection hood directly above or to the side of the furnace opening and connecting it to downstream processing equipment via pipelines to capture and treat polluted flue gas. While this method can solve the problem of flue gas diffusion to some extent, it has significant limitations in actual production, especially in terms of the convenience of material feeding operations.

[0004] Because dust hoods need to cover the furnace opening area to ensure high flue gas collection efficiency, their installation position often directly obstructs the space above the furnace opening. When aluminum ingots, alloy materials, or auxiliary materials need to be added to the furnace, the fixed dust hood will create a physical obstacle, making it difficult to directly perform the feeding operation. To solve this problem, some companies adopt the method of disassembling the dust hood before feeding materials, but each disassembly and reassembly requires additional manpower and time, which not only interrupts the smelting process and reduces production efficiency, but may also cause the sealing performance of the dust hood to deteriorate due to frequent operation, affecting the subsequent flue gas collection effect.

[0005] Other options involve feeding material from the side furnace opening that is not covered by the dust collection hood. However, due to the shape of the molten pool and the temperature distribution inside the furnace, feeding material from one side can easily cause the material to accumulate in a local area inside the furnace, making it impossible to disperse quickly and evenly. This can lead to problems such as uneven melting temperature and insufficient mixing of alloy components, which can affect the final quality of the molten aluminum. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-4This utility model provides a technical solution: A dust collection hood for aluminum smelting furnaces that facilitates material loading, comprising: Flue gas dust collection hood 1 is installed directly above the furnace opening of the aluminum melting furnace; A vertical rod 2 is fixedly installed on one side of the aluminum melting furnace opening. A rotatable horizontal cantilever 3 is installed on the vertical rod 2. A support arm 4 is installed below the horizontal cantilever 3. One end of the support arm 4 is fixedly connected to the horizontal cantilever 3, and the other end of the support arm 4 is rotatably connected to the horizontal cantilever 3. Both the horizontal cantilever 3 and the support arm 4 are rotatably connected to the vertical rod 2 through bearing components. The horizontal cantilever 3 can rotate around the vertical rod 2.

[0020] Lifting component 5 is mounted on horizontal cantilever 3 and is used to drive the flue gas dust collection hood 1 to lift and lower. The rotating adjustment component 6 is located at the rotating connection 7. The rotating adjustment component 6 is used to drive the horizontal cantilever 3, the support arm 4 and the flue gas dust collection hood 1 to rotate. The horizontal cantilever 3 and the rotating connection 7 are both rotatably connected to the vertical rod 2 through bearing components. The horizontal cantilever 3 can rotate around the vertical rod 2.

[0021] The flue gas guiding component 8 includes a flue gas dust collection hood interface 9 and a flue gas treatment pipe 10. The flue gas dust collection hood interface 9 is located between the aluminum furnace opening and the vertical rod 2. The flue gas dust collection hood interface 9 is connected to the flue gas dust collection hood 1 and is connected to the flue gas treatment pipe 10. The flue gas treatment pipe 10 is connected to the flue gas treatment equipment. The flue gas treatment equipment is not limited, and any method commonly used by those skilled in the art is applicable. When feeding is required, the lifting component 5 drives the flue gas dust collection hood 1 to rise, thereby disconnecting the flue gas dust collection hood 1 from the flue gas guiding component 8. Then, the rotation adjustment component 6 drives the horizontal cantilever 3 and the flue gas dust collection hood 1 to rotate, so that the flue gas dust collection hood 1 is offset from the aluminum furnace opening, facilitating feeding operations.

[0022] Furthermore, the flue gas dust collection hood 1 includes a circular shell 11, a square connector 12, and a vertical pipe 13. The circular shell 11 is a cylindrical hollow structure with an open bottom. The vertical pipe 13 is located on one side of the circular shell 11 and is vertically downward. The vertical pipe 13 is connected to the circular shell 11 through the square connector 12.

[0023] Furthermore, the lifting assembly 5 includes a first servo motor 14, a stranded reel 15, a fixed pulley 16, and a steel wire rope 17. The first servo motor 14 is fixedly mounted on the horizontal cantilever 3. The stranded reel 15 is coaxially and fixedly connected to the output end of the first servo motor 14. The fixed pulley 16 is disposed inside the horizontal cantilever 3. One end of the steel wire rope 17 is wound around the stranded reel 15, and the other end of the steel wire rope 17 passes through the fixed pulley 16 and is fixedly connected to the top of the flue gas dust collection hood 1. The first servo motor 14 can drive the stranded reel 15 to rotate, thereby realizing the winding and unwinding of the steel wire rope 17, and thus realizing the raising and lowering of the flue gas dust collection hood 1.

[0024] Furthermore, two sets of the stranding reel 15, fixed pulleys 16, and wire ropes 17 are provided. The distances of the two sets of fixed pulleys 16 from the stranding reel 15 are unequal, and the fixing points of the two sets of wire ropes 17 to the top of the flue gas dust collection hood 1 are different. The two-set configuration makes the lifting more stable, and the flue gas dust collection hood 1 is less likely to tip over or shake. Moreover, this design only uses one power source (the first servo motor 14), making it convenient and simple to use.

[0025] Furthermore, the rotation adjustment assembly 6 includes a large gear 18, a small gear 19, and a second servo motor 20. The large gear 18 is fixedly mounted on the vertical rod 2, the small gear 19 is located on one side of the large gear 18, and the small gear 19 is meshed with the large gear 18. The second servo motor 20 is fixedly mounted on the rotation connector 7, and the output shaft of the second servo motor 20 is coaxially fixedly connected with the small gear 19.

[0026] Furthermore, the flue gas dust collection hood interface 9 has an opening that faces vertically upwards, and the flue gas dust collection hood interface 9 is connected to the lower opening of the vertical pipe 13. A recessed bend 21 and an anti-backflow vertical pipe 22 are provided on one side of the flue gas dust collection hood interface 9, and the flue gas dust collection hood interface 9 is connected to the recessed bend 21 and the anti-backflow vertical pipe 22. The anti-backflow vertical pipe 22 is connected to the flue gas treatment pipeline 10.

[0027] Furthermore, the top of the anti-backflow riser 22 is at a higher level than the top of the flue gas dust collection hood interface 9. The anti-backflow riser 22 is used to prevent flue gas from flowing back. Since the flue gas temperature is high, it will flow upward without driving force. Because the anti-backflow riser 22 is higher, if the flue gas flows back, it needs to overcome the lift force corresponding to the height difference.

[0028] Furthermore, the vertical rod 2 is positioned between the two sets of aluminum furnace openings, and each set of aluminum furnace openings is equipped with a flue gas guiding component 8 between it and the flue gas dust collection hood 1. The flue gas dust collection hood 1 can be rotated to be above either set of aluminum furnace openings. When the entire flue gas dust collection hood 1 can be selectively adjusted to be above either set of aluminum furnace openings, the other aluminum furnace opening must be closed to prevent untreated polluted gas from escaping.

Anti-backflow riser 22: A component of the flue gas guiding assembly 8, a vertical pipe structure connecting the sunken bend 21 and the flue gas treatment pipe 10, with its top horizontal height higher than the flue gas dust collection hood interface 9, used to prevent flue gas backflow.

[0030] Working Principle: During normal smelting operations in the aluminum furnace, when it is necessary to collect polluted flue gas, the flue gas dust collection hood 1 is adjusted to be directly above the furnace opening via the lifting component 5, and the vertical pipe 13 at the bottom of the flue gas dust collection hood 1 is tightly connected to the flue gas dust collection hood interface 9 located between the furnace opening and the vertical rod 2. At this time, the polluted flue gas generated by the furnace will first enter the circular shell 11 of the flue gas dust collection hood 1, be introduced into the vertical pipe 13 through the square connector 12, and then enter the subsequent channel through the flue gas dust collection hood interface 9. Since the flue gas dust collection hood interface 9 connects the sunken bend pipe 21 and the anti-backflow vertical pipe 22, and the top of the anti-backflow vertical pipe 22 is higher than the top of the flue gas dust collection hood interface 9, the high-temperature flue gas will naturally flow upward without external force. The height difference of the anti-backflow vertical pipe 22 can effectively prevent the flue gas from flowing back. Finally, the flue gas enters the flue gas treatment pipeline 10 through the anti-backflow vertical pipe 22 and is transported to the external flue gas treatment equipment for purification, achieving efficient collection of pollutants. During this process, the horizontal cantilever 3 and the support arm 4 are stably connected to the vertical rod 2 through bearing components. One end of the support arm 4 is fixed to the horizontal cantilever 3, and the other end is rotatably connected to the flue gas dust collection hood 1 through the rotating connector 7. Together, they provide stable support for the flue gas dust collection hood 1, preventing it from shifting due to flue gas impact or its own weight.

[0031] When it is necessary to feed material into the aluminum furnace, the device moves to clear the obstruction of the flue gas dust collection hood 1 from the furnace opening: First, the lifting assembly 5 starts working, and the first servo motor 14 drives the twisted wire reel 15 to rotate. Since the twisted wire reel 15 is connected to the fixed pulley 16 by a steel wire rope 17, and the two sets of twisted wire reels 15, fixed pulleys 16, and steel wire ropes 17 are fixed at different points on the top of the flue gas dust collection hood 1, the steel wire rope 17 will smoothly drive the flue gas dust collection hood 1 to rise when it is wound up, until the vertical pipe 13 is completely disengaged from the flue gas dust collection hood interface 9, thus disconnecting the flue gas flow. Conveying channel; Subsequently, the rotation adjustment component 6 is activated, and the second servo motor 20 fixed on the rotating connector 7 drives the pinion 19 to rotate. Since the pinion 19 meshes with the large gear 18 fixed on the vertical rod 2, when the pinion 19 rotates around the large gear 18, it will drive the rotating connector 7, the support arm 4 and the horizontal cantilever 3 to rotate synchronously around the vertical rod 2, thereby causing the flue gas dust collection hood 1 to rotate with the horizontal cantilever 3 to a position away from the furnace opening, completely freeing up the space above the furnace opening, making it convenient for operators to directly and evenly feed materials into the furnace without disassembling any parts.

[0032] After feeding is completed, the device is reset in the reverse process: the rotating adjustment component 6 drives the horizontal cantilever 3 back to the top of the furnace opening, and the lifting component 5 controls the flue gas dust collection hood 1 to descend, so that the vertical pipe 13 reconnects with the flue gas dust collection hood interface 9, restoring the flue gas collection function.

[0033] The vertical rod 2 is set between the two sets of furnace openings. By adjusting the rotating adjustment component 6, the flue gas dust collection hood 1 can be rotated to the top of either set of furnace openings. By simply closing the unused furnace openings, one device can collect flue gas from both sets of furnaces, thereby improving equipment utilization.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
