Description

Technical Field

[0001] This invention relates to the field of recycled aluminum technology, and more particularly to a raw material melting and impurity removal device used in aluminum rod production. Background Technology

[0002] In the aluminum processing industry, aluminum rods, as core semi-finished products in downstream processes such as extrusion and forging, directly determine the mechanical properties and processing qualification rate of the final products through their internal purity and structural uniformity. With the advancement of resource recycling policies and the rising cost of primary aluminum production, the production scale of recycled aluminum rods using waste aluminum as raw material continues to expand. As the core link in the production of recycled aluminum rods, the stability and efficiency of the "raw material melting and impurity removal" process have become key bottlenecks restricting product quality. Recycled aluminum raw materials (such as waste building profiles, waste aluminum cans, aluminum shavings, etc.) have a complex composition. In addition to aluminum matrix, they also contain metallic impurities such as iron, copper, and zinc, non-metallic impurities such as plastics and paint, and gaseous impurities such as hydrogen. To meet the purity requirements of aluminum rod production (e.g., 6-series aluminum rods need to control iron content ≤0.7% and hydrogen content ≤0.15ml / 100gAl), a multi-step process of "preliminary slag removal to remove mechanical impurities - refining and degassing - chemical impurity removal" must be completed during the melting process. Among these, the precise addition and uniform dispersion of impurity removal agents (such as slag removers, refining agents, and chemical impurity removal agents) are the core prerequisites for ensuring the impurity removal effect.

[0003] In current aluminum rod production, the mainstream raw material melting and impurity removal devices mainly rely on "manual feeding + mechanical stirring" or "simple single-point feeder + static diffusion" to add reagents. Such devices and processes have significant defects, mainly manifested in uneven reagent distribution.

[0004] Existing equipment mostly adopts a single-point feeding structure at the furnace opening. After the reagent is added from a single position at the top of the smelting furnace, it is difficult for the reagent to diffuse to the entire area of ​​the aluminum liquid in the furnace on its own due to the viscosity of the aluminum liquid itself (the viscosity of aluminum liquid at 700-720℃ is about 0.0012 Pa・s). It is easy to form a "reagent enrichment zone" near the feeding point, while a "reagent blank zone" appears in the area outside the feeding point. This will lead to a serious imbalance in the impurity removal effect of aluminum liquid, incomplete removal of impurities, large fluctuations in the performance of aluminum rod products, and limitations on high-end applications. Summary of the Invention

[0005] Given the problem of uneven dosing in existing technologies, a raw material melting and impurity removal device for aluminum rod production is proposed.

[0006] This application provides a raw material melting and impurity removal device for aluminum rod production, the purpose of which is to uniformly add reagents.

[0007] The technical solution of the present invention is as follows: a raw material melting and impurity removal device for aluminum rod production, used for aluminum liquid treatment, including a furnace, an installation plate set above the furnace, a suspension beam set at the top of the installation plate, a stirring rod set at the bottom of the installation plate, and a feeding component set inside the installation plate. The feeding component specifically includes a rotating groove opened at the top of the installation plate, a rotating plate set inside the rotating groove, a cover plate set at the top opening of the rotating groove, a feeding hole and an air blowing hole opened in the bottom wall of the rotating groove, a material storage trough and an air inlet trough opened at the top of the rotating plate, a feeding connector and an air inlet connector set at the top of the cover plate, a connecting air hole opened in the bottom wall of the inner side of the air inlet trough, and a driving component set above the cover plate. The bottom wall of the rotating trough is set in two stages. The feeding holes are arranged in a circular array on the lower stage of the rotating trough and extend into the air blowing holes. The air blowing holes are arranged in a circular array on the upper stage of the rotating trough. The storage trough extends through to the bottom of the rotating disk and connects with the feeding holes. The upper end of the storage trough connects with the feed connector. The connecting air hole connects with the air blowing hole. The air inlet connector connects with the air inlet trough.

[0008] Furthermore, the storage tank is arc-shaped and simultaneously covers at least two feeding holes.

[0009] Furthermore, the storage tank is located on the side of the connecting air hole.

[0010] Furthermore, the dispensing component also includes an upper groove at the top of the rotating disk, a lower groove at the bottom of the rotating disk, a through hole between the upper and lower grooves, and a ventilation hole at the top of the cover plate. Both the upper and lower grooves are arc-shaped, with the included angle between the two ends of the upper groove being no less than 180 degrees, and the included angle between the two ends of the lower groove being greater than the included angle between the two ends of the upper groove. The through hole is connected to the feeding hole.

[0011] Furthermore, the drive assembly specifically includes an outer sleeve disposed on the top of the rotating disk, a rotating gear disposed on the outer side of the outer sleeve, a rotating ring disposed on the outer side of the stirring rod, a mounting bracket disposed on the top of the cover plate, a rotating shaft disposed on the side of the mounting bracket, a transmission gear disposed on the rotating shaft near the end of the stirring rod, and a pawing tooth disposed on the outer side of the rotating ring to drive the transmission gear to rotate. The outer sleeve is fitted on the outside of the stirring rod, and the outer sleeve extends upward to form a cover plate. The rotating gear meshes with the transmission gear, and the actuating teeth extend into the tooth groove of the transmission gear. The rotating ring is located above the rotating gear.

[0012] Furthermore, the outer diameter circumference of the transmission gear is smaller than that of the rotating gear.

[0013] Furthermore, a torsion spring is installed between the rotating ring and the stirring rod.

[0014] Furthermore, a slag removal assembly is provided at the bottom of the mounting plate. The slag removal assembly specifically includes a telescopic rod disposed on the bottom wall of the mounting plate and a sluice tube disposed at the bottom end of the telescopic rod. The telescopic rod extends into the furnace, and the sluice tube is C-shaped with the opening of the C-shape flush with the surface of the molten aluminum.

[0015] Furthermore, the slag removal assembly also includes an extension rod disposed at the top of the sluice tube, and the sluice tube is rotatably connected to the telescopic rod via the extension rod.

[0016] Furthermore, the slag removal assembly also includes an adjusting gear disposed at the connection between the telescopic rod and the extension rod, and a rack disposed at the bottom of the mounting plate.

[0017] The beneficial effects of this invention are: 1. By setting up a dispensing component, when the agent needs to be dispensed, the drive component drives the rotating disc to rotate. When the storage tank rotates to below the feed connector, the agent in the tank falls into the storage tank. When the storage tank rotates to above the feeding hole, the agent falls into the feeding hole. Then, the air pump blows air into the blowing hole through the air inlet and connecting air hole. The flowing air generates negative pressure, which entrains the agent in the feeding hole into the airflow and sprays it out of the blowing hole with the airflow, evenly spraying it on the aluminum liquid. Then, other blowing holes spray the agent in sequence. This can achieve uniform, stable and precise dispensing of the agent and improve the impurity removal effect.

[0018] Meanwhile, the above-mentioned delivery process does not require close-range manual operation, making the work process safer.

[0019] 2. By setting up upper and lower grooves, when the agent in the feeding hole is sucked up by the air blowing hole, the upper part of the feeding hole is connected to the outside through the lower groove, through hole, upper groove and air exchange hole. This allows the end of the feeding hole away from the air blowing hole to replenish air into the feeding hole, making it easier for the agent in the feeding hole to be drawn into the air blowing hole, avoiding agent residue in the feeding hole and affecting the accuracy of agent dispensing.

[0020] 3. By setting up a drive assembly, the transmission gear is pulled apart from the rotating gear and the actuating gear by the rotating shaft, so that the rotating disk stops rotating and no longer dispenses the agent. Instead, the transmission gear is pushed by the rotating shaft to mesh with the rotating gear and the actuating gear. The stirring rod drives the rotating ring to rotate one revolution. The actuating gear can then be used to rotate the transmission gear by a certain angle. Then, the rotating gear drives the outer sleeve and the rotating disk to rotate synchronously. This makes it easier to control the start and stop of the rotating disk.

[0021] 4. By setting up a slag removal component, when the stirring rod stirs the molten aluminum, the impurities in it float to the surface. As the molten aluminum flows in the furnace, the impurities enter the sluice tube when it passes through the tube and are collected. Then, the telescopic rod lifts the sluice tube upwards, and the impurities in the sluice tube can be removed from a distance using tools such as a rake. This is more efficient and safer.

[0022] 5. By setting an adjusting gear and rack, when the telescopic rod stretches the molten aluminum cylinder, the adjusting gear meshes with the rack, and the rack pushes the adjusting gear to rotate. The molten aluminum and impurities in the molten aluminum cylinder shake together, which can further promote the separation of molten aluminum and impurities and reduce molten aluminum loss.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figures 1-12 This is the first embodiment of the present invention, which provides a raw material melting and impurity removal device for aluminum rod production, used for aluminum liquid treatment. It includes a furnace 1, an installation plate 2 disposed above the furnace 1, a suspension beam 3 disposed at the top of the installation plate 2, a stirring rod 4 disposed at the bottom of the installation plate 2, and a feeding component 5 disposed inside the installation plate 2. The feeding component 5 specifically includes a rotating groove 51 opened at the top of the installation plate 2, a rotating plate 52 disposed inside the rotating groove 51, a cover plate 53 disposed at the top opening of the rotating groove 51, a feeding hole 54 and an air blowing hole 57 opened in the inner bottom wall of the rotating groove 51, a material storage groove 55 and an air inlet groove 58 opened at the top of the rotating plate 52, a feeding connector 56 and an air inlet connector 510 disposed at the top of the cover plate 53, a connecting air hole 59 opened in the inner bottom wall of the air inlet groove 58, and a driving component disposed above the cover plate 53.

[0027] Specifically, furnace 1 is cylindrical with an opening at the top. A platform is connected above the suspension beam 3, and the platform is connected via an extension arm and lifting equipment. An outlet is located at the outer contour of the top of furnace 1. The bottom wall of the rotating trough 51 is two-tiered. A stirring rod 4 passes through the mounting plate 2, rotating plate 52, and cover plate 53, extending above the mounting plate 2. A drive motor is connected to the top of the stirring rod 4. The rotating plate 52 is rotatably mounted within the rotating trough 51. The cover plate 53 is fixed to the mounting plate 2 with bolts, covering the top of the rotating plate 52. Feeding holes 54 are arranged in a circular array on the lower tier of the rotating trough 51. The feeding holes 54 are divided into three sections: vertical, folded, and horizontal. The flat section extends into the air blowing hole 57, which is arranged in a circular array on the upper step of the rotating groove 51. The air blowing hole 57 penetrates to the bottom wall of the mounting plate 2. The material storage tank 55 penetrates to the bottom of the rotating plate 52 and connects with the feeding hole 54. The upper end of the material storage tank 55 connects with the feeding connector 56. The material storage tank 55 is a cone shape with a larger upper part and a smaller lower part. A material tank is installed above the feeding connector 56 for replenishing the agent into the dispensing component 5. The agent is specifically in powder or granular form. The air inlet groove 58 is annular and distributed along the outer contour of the mounting plate 2. The connecting air hole 59 connects to the air blowing hole 57. The air inlet connector 510 connects to the air inlet groove 58. The upper end of the air inlet connector 510 is connected to the air pump.

[0028] By setting up the dispensing component 5, when the agent needs to be dispensed, the drive component drives the rotating disk 52 to rotate. When the storage tank 55 rotates to below the feed connector 56, the agent in the tank falls into the storage tank 55. When the storage tank 55 rotates to above the feeding hole 54, the agent falls into the feeding hole 54. Then, the air pump blows air into the blowing hole 57 through the air inlet 58 and the connecting air hole 59. The flowing air generates negative pressure, which entrains the agent in the feeding hole 54 into the airflow and sprays it out of the blowing hole 57 with the airflow, evenly spraying it above the aluminum liquid. Then, the other blowing holes 57 spray the agent in sequence. In this way, the agent can be evenly, stably and accurately spread, improving the impurity removal effect.

[0029] Meanwhile, the above-mentioned delivery process does not require close-range manual operation, making the work process safer.

[0030] Specifically, the storage tank 55 is arc-shaped and covers at least two feeding holes 54 at the same time. This can prolong the air flow time in the air blowing hole 57 and prevent residual medicine in the feeding hole 54.

[0031] Specifically, the storage tank 55 is located in the same direction as the connecting air hole 59. That is, when the cover plate 53 rotates, the connecting air hole 59 follows behind the storage tank 55. In this way, when the agent is added into the feeding hole 54, it is not affected by other conditions, so that each feeding hole 54 contains an equal amount of agent, making the agent addition more uniform.

[0032] The dispensing component 5 also includes an upper groove 511 on the top of the rotating disk 52, a lower groove 512 on the bottom of the rotating disk 52, a through hole 513 between the upper groove 511 and the lower groove 512, and a ventilation hole 514 on the top of the cover plate 53.

[0033] Specifically, both the upper groove 511 and the lower groove 512 are arc-shaped. The included angle between the two ends of the upper groove 511 is not less than 180 degrees, and the included angle between the two ends of the lower groove 512 is greater than the included angle between the two ends of the upper groove 511. The through hole 513 is located inside the outline of the connecting air hole 59, and the through hole 513 is connected to the feeding hole 54.

[0034] By setting the upper groove 511 and the lower groove 512, when the agent in the feeding hole 54 is sucked up by the air blowing hole 57, the upper part of the feeding hole 54 is connected to the outside through the lower groove 512, the through hole 513, the upper groove 511 and the air exchange hole 514. This allows the end of the feeding hole 54 away from the air blowing hole 57 to be supplied with air, making it easier for the agent in the feeding hole 54 to be drawn into the air blowing hole 57, avoiding agent residue in the feeding hole 54 and affecting the accuracy of agent dispensing.

[0035] The drive assembly specifically includes an outer sleeve 515 disposed on the top of the rotating disk 52, a rotating gear 516 disposed on the outside of the outer sleeve 515, a rotating ring 517 disposed on the outside of the stirring rod 4, a mounting bracket 518 disposed on the top of the cover plate 53, a rotating shaft 519 disposed on the side of the mounting bracket 518, a transmission gear 520 disposed on the end of the rotating shaft 519 near the stirring rod 4, and a pawing tooth 521 disposed on the outside of the rotating ring 517 to drive the transmission gear 520 to rotate.

[0036] Specifically, the outer sleeve 515 is fitted onto the outside of the stirring rod 4, and the outer sleeve 515 extends upward to form a cover plate 53. The outer sleeve 515 is fixedly connected to the rotating disk 52. The rotating gear 516 is engaged with the outside of the outer sleeve 515 and meshes with the transmission gear 520. The mounting bracket 518 is fixedly connected to the cover plate 53. The rotating ring 517 is engaged with the stirring rod 4. The rotating shaft 519 is rotatably connected to the mounting bracket 518. The rotating shaft 519 can also be slidably connected to the mounting bracket 518 and limited by bolts. The actuating tooth 521 extends into the tooth groove of the transmission gear 520. The rotating ring 517 is located above the rotating gear 516. The outer diameter circumference of the transmission gear 520 is smaller than that of the rotating gear 516.

[0037] By setting up a drive assembly, the transmission gear 520 is pulled apart from the rotating gear 516 and the actuating tooth 521 by the rotating shaft 519, so that the rotating disk 52 stops rotating and no longer dispenses the medicine. Instead, the transmission gear 520 is pushed by the rotating shaft 519 to mesh with the rotating gear 516 and the actuating tooth 521. The stirring rod 4 drives the rotating ring 517 to rotate one revolution. The actuating tooth 521 can then be used to actuate the transmission gear 520 to rotate a certain angle. Then, the rotating gear 516 drives the outer sleeve 515 and the rotating disk 52 to rotate synchronously. This makes it easier to control the start and stop of the rotating disk 52.

[0038] Specifically, a torsion spring is installed between the rotating ring 517 and the stirring rod 4 to facilitate the engagement of the actuating gear 521 with the transmission gear 520.

[0039] Example 2, refer to Figure 1 , Figures 8-14 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a slag removal component 6 is provided at the bottom of the mounting plate 2. The slag removal component 6 specifically includes a telescopic rod 61 provided on the bottom wall of the mounting plate 2 and a sluice tube 62 provided at the bottom end of the telescopic rod 61.

[0040] Specifically, the top of the telescopic rod 61 is fixedly connected to the mounting plate 2, and the telescopic rod 61 extends into the furnace 1. The telescopic rod 61 is located in the distribution gap of the air blowing holes 57. The sluice tube 62 is C-shaped, and the opening of the C is flush with the surface of the molten aluminum. The direction of the opening of the C is opposite to the direction of stirring of the molten aluminum. When adding the reagent, the telescopic rod 61 is lowered to immerse the sluice tube 62 into the molten aluminum to avoid affecting the addition of the reagent.

[0041] By setting up the slag removal component 6, when the stirring rod 4 stirs the molten aluminum, the impurities in it float to the surface. The molten aluminum flows in the furnace 1 and when it passes through the sluice tube 62, the impurities enter the sluice tube 62 and are collected. Then the telescopic rod 61 lifts the sluice tube 62 upward, and the impurities in the sluice tube 62 can be removed from a distance using tools such as a "rake". This is more efficient and safer.

[0042] Specifically, the slag removal assembly 6 also includes an extension rod 63 disposed at the top of the slag removal cylinder 62. The slag removal cylinder 62 is rotatably connected to the telescopic rod 61 through the extension rod 63. The extension rod 63 is welded to the slag removal cylinder 62, thereby raising the rotation point of the telescopic rod 61 and the slag removal cylinder 62 to prevent the aluminum liquid from affecting the flexibility of the rotation point.

[0043] Specifically, the slag removal assembly 6 also includes an adjusting gear 64 located at the connection between the telescopic rod 61 and the extension rod 63, the adjusting gear 64 being fixedly connected to the extension rod 63, and a rack 65 located at the bottom of the mounting plate 2, the rack 65 being fixedly connected to the mounting plate 2.

[0044] By setting up adjusting gear 64 and rack 65, when telescopic rod 61 stretches the sluice cylinder 62, when the sluice cylinder 62 leaves the molten aluminum, adjusting gear 64 meshes with rack 65, rack 65 pushes adjusting gear 64 to rotate, and molten aluminum and impurities in sluice cylinder 62 shake together, which can further promote the separation of molten aluminum and impurities and reduce molten aluminum loss.

[0045] The remaining structure is the same as that in Example 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
