Description

Technical Field

[0001] This invention relates to the field of aluminum alloy production technology, and in particular to a pulse-type circulating heating device for solid-liquid treatment of aluminum alloys. Background Technology

[0002] Aluminum alloy production involves adding alloying elements such as copper and magnesium to aluminum as a base. After melting, preparation, degassing, impurity removal, and refining, the alloy is cast into ingots. These ingots are then subjected to hot working processes such as heating, extrusion, or rolling, as well as subsequent cold working, heat treatment, and surface treatment to produce aluminum alloy products with the required shapes and properties.

[0003] Aluminum alloy solid-liquid treatment equipment mainly involves the solution treatment and supporting quenching process in the heat treatment of aluminum alloys. Its core equipment includes a solution furnace, a quenching device and related automatic control system. As the core equipment of heat treatment, the solution furnace is used to mix metal raw materials in a certain proportion, and then heat treat them to finally form aluminum alloy products.

[0004] During the aluminum alloy melting stage, workers need to place aluminum plates into the furnace one by one. This process is relatively slow to prevent the molten aluminum from splashing out. During the melting stage, an oxide layer and other impurities will form on the surface of the molten metal. Therefore, it is necessary to frequently remove the oxide layer and impurities from the surface of the molten metal to improve the quality of the finished product. However, in the traditional way, workers use rakes to remove the slag from the furnace. This method is risky and the cleaning is not thorough. Therefore, in order to solve the above problems, a pulse-type circulating heating aluminum alloy solid-liquid treatment device is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulse-type cyclic heating aluminum alloy solid-liquid treatment device.

[0007] The above technical solution further includes: Multiple casters are fixedly installed around the bottom circumference of the furnace bottom plate.

A small gear is fixedly installed at the output end of the rotary motor. A mounting base is rotatably connected to the top of the furnace bottom plate. A large gear ring is fixedly installed on the outer side of the mounting base. The small gear meshes with the mounting base.

[0008] The heating furnace is mounted on a mounting base via multiple mounting blocks. A spiral heating rod is fixedly installed inside the heating furnace, and the spiral heating rods are spirally distributed on the inner side of the heating furnace.

[0009] The dual-station assembly also includes a support plate fixedly installed on a fixed base. A directional motor is fixedly installed on the inner side of the fixed base. A directional driving sprocket is fixedly connected to the output end of the directional motor. A directional driven sprocket is symmetrically rotatably connected to the support plate.

A threaded screw is rotatably connected to the inner side of the slide rail. The threaded screw is threadedly connected to the threaded slider. Sliding rods are symmetrically fixedly connected to both sides of the slide rail. The threaded slider slides relative to the sliding rods. Guide sprockets are fixedly installed on both the top and bottom sides of the inner side of the slide rail. An auxiliary fixing chain is sleeved between the two guide sprockets. The beginning and end of the auxiliary fixing chain are fixedly connected to the threaded slider.

[0011] A drive sprocket is fixedly connected to the bottom outer side of the threaded screw. A lifting motor is fixedly installed on the side of the slide rail away from the threaded slider. A drive master sprocket is fixedly connected to the output end of the lifting motor. A drive chain is sleeved between the drive master sprocket and the drive slave sprocket.

[0012] The first fixed arm is fixedly connected to one of the threaded sliders. The impurity removal and degassing assembly also includes a stirring motor fixedly installed on the top of the first fixed arm. A hollow stirring rod is fixedly installed at the output end of the stirring motor. A first cover plate is installed at the bottom of the first fixed arm. An air inlet plate is fixedly installed at the bottom of the first cover plate and is rotatably connected to the hollow stirring rod. The air inlet pipe is connected to the air inlet plate. The hollow stirring rod is fixedly connected to the stirring impeller, and the hollow stirring rod and the stirring impeller are interconnected.

[0013] A collection tray is provided on one side of the heating furnace. Collection legs are symmetrically and fixedly connected to the bottom of the collection tray.

[0016] The present invention has the following beneficial effects: In this invention, a cleaning and degassing component and a feeding component are respectively set on the slide rail, and the two workstations can be operated independently and cooperate with each other. This layout allows the two key processes of feeding and cleaning and degassing to be carried out in parallel, which significantly improves the overall production efficiency.

[0017] In this invention, traditional aluminum alloy melting processes require workers to operate at close range for feeding and degassing, facing safety risks such as splashing of high-temperature molten aluminum and inhalation of harmful gases. This equipment, however, automates the feeding and degassing processes through its automated degassing and feeding components, significantly reducing manual intervention. Attached Figure Description

[0020] The technical solutions of 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] like Figure 1 — Figure 12 As shown, the present invention proposes a pulse-type circulating heating aluminum alloy solid-liquid treatment device, including a furnace bottom plate 10 and a fixed base 2. A heating furnace 1 is rotatably mounted on the furnace bottom plate 10. A dual-station assembly is provided on the fixed base 2. The dual-station assembly includes symmetrically arranged slide rails 24. The angle of the slide rails 24 is adjustable. Threaded sliders 23 are slidably arranged on the slide rails 24. One threaded slider 23 is provided with a degassing and impurity removal component, and the other threaded slider 23 is provided with a feeding component. The impurity removal and degassing assembly includes a first fixed arm 5, on which an air inlet pipe 51 and a feed pipe 52 are provided. A stirring disc 54 is rotatably provided at the bottom of the first fixed arm 5. The air inlet pipe 51 and the stirring disc 54 are used to introduce inert gas into the molten aluminum alloy liquid, and the feed pipe 52 is used to add impurity removal agent. The feeding assembly includes a second fixed arm 6, on which a material rack 62 is rotatably mounted for placing aluminum plates; Furthermore, in the solid-liquid treatment process of aluminum alloy, the aluminum material first needs to be melted. Then, the remaining metals are added into the heating furnace 1 in proportion to form an alloy melt. The material is first fed using a feeding component to avoid splashing during manual feeding. After the solid metal becomes molten, it is degassed and de-gassed until the aluminum alloy melt meets the predetermined standards.

[0022] like Figure 3 — Figure 4 As shown, multiple moving wheels 12 are fixedly installed on the bottom circumference of the furnace bottom plate 10, a hydraulic support 11 is installed at the center of the furnace bottom plate 10, a rotary motor 13 is fixedly installed on the side of the furnace bottom plate 10, a small gear 14 is fixedly installed at the output end of the rotary motor 13, and a mounting base 17 is rotatably connected to the top of the furnace bottom plate 10. A large gear ring 15 is fixedly installed on the outer side of the mounting base 17, and the small gear 14 meshes with the mounting base 17. The heating furnace 1 is mounted on the mounting base 17 via multiple mounting blocks 18. A spiral heating rod 16 is fixedly installed inside the heating furnace 1, and the spiral heating rod 16 is spirally distributed on the inner side of the heating furnace 1. Furthermore, during the aluminum alloy melting process, the heating furnace 1 needs to rotate to cooperate with the feeding assembly and the impurity removal and gas storage assembly. First, the heating furnace 1 is hoisted onto the mounting base 17. Then, using multiple mounting blocks 18, the heating furnace 1 is installed on the mounting base 17. During the rotation of the heating furnace 1, the small gear 14 is driven to rotate by the drive motor 13. The small gear 14 meshes with the large gear ring 15, and the large gear ring 15 is fixedly connected to the mounting base 17. Therefore, the rotation of the heating furnace 1 can be completed by driving the drive motor 13. Furthermore, the heating furnace 1 is equipped with a spiral heating rod 16, and vertical heating rods are also vertically fixed on the spiral heating rod 16. During the heating process, a high-energy electric pulse is applied to the spiral heating rod 16. In each heating stage, the pulse current rapidly raises the aluminum alloy to the target temperature, and then the temperature naturally decreases during the cooling stage. This periodic temperature change can promote the uniform distribution of solute atoms, prevent coarsening of precipitated phases, and further enhance the material properties through dislocation multiplication induced by thermal stress.

[0023] like Figure 5 — Figure 6 As shown, the dual-station assembly also includes a support plate 20 fixedly installed on a fixed base 2. A directional motor 28 is fixedly installed on the inner side of the fixed base 2. A directional drive sprocket 210 is fixedly connected to the output end of the directional motor 28. A directional driven sprocket 213 is symmetrically rotatably connected to the support plate 20. A directional chain 211 is sleeved and connected between the directional drive sprocket 210 and the two directional driven sprockets 213. A rotating disk 21 is fixedly connected to the top of the driven sprocket 213. A slide rail 24 is fixedly connected to the rotating disk 21. A threaded screw 25 is rotatably connected to the inner side of the slide rail 24. The threaded screw 25 is threadedly connected to the threaded slider 23. Sliding rods 22 are symmetrically fixedly connected to both sides of the slide rail 24. The threaded slider 23 slides relative to the sliding rods 22. Guide sprockets 214 are fixedly installed on both the top and bottom sides of the inner side of the slide rail 24. An auxiliary fixing chain 215 is sleeved between the two guide sprockets 214. The beginning and end of the auxiliary fixing chain 215 are fixedly connected to the threaded slider 23. A drive sprocket 27 is fixedly connected to the bottom outer side of the threaded screw 25. A lifting motor 29 is fixedly installed on the side of the slide rail 24 away from the threaded slider 23. A drive sprocket 212 is fixedly connected to the output end of the lifting motor 29. A drive chain 26 is sleeved between the drive sprocket 212 and the drive sprocket 27. Furthermore, in actual use, the heating furnace 1 needs to be continuously fed and degassed alternately. The dual-station assembly can switch freely between the degassed assembly and the feeding assembly. During the operation of the dual-station assembly, the directional motor 28 is started first. The output end of the directional motor 28 drives the directional drive sprocket 210 to rotate. Since the directional drive sprocket 210 and the two directional driven sprockets 213 are connected by a directional chain 211, the directional chain 211 drives the two directional driven sprockets 213 to rotate on the support plate 20 under the drive of the directional drive sprocket 210. The top of the directional chain 211 is fixedly connected to the rotating plate 21, so the movement of the directional chain 211 will drive the rotating plate 21 to rotate. Since the slide rail 24 is fixedly connected to the rotating plate 21, the slide rail 24 rotates with the rotating plate 21, realizing the angle adjustment of the entire dual-station assembly to adapt to the processing needs of different positions of the aluminum liquid in the furnace under different working conditions. Furthermore, since the phase difference between the two threaded sliders 23 is constant, the switching between the impurity removal and degassing components and the feeding component can be completed at will by the reciprocating forward and reverse rotation of the directional motor 28.

[0024] When it is necessary to control the movement of the threaded slider 23 on the slide rail 24, the lifting motor 29 is started. The output end of the lifting motor 29 drives the main drive sprocket 212 to rotate. The drive chain 26 transmits the power of the main drive sprocket 212 to the driven slave sprocket 27. The driven slave sprocket 27 drives the threaded screw 25 to rotate inside the slide rail 24. The threaded screw 25 is threadedly connected to the threaded slider 23. When the threaded screw 25 rotates, the threaded slider 23 will move linearly along the threaded screw 25. At the same time, the threaded slider 23 slides relative to the slide rod 22. The slide rod 22 plays the role of guiding and stabilizing the movement of the threaded slider 23, ensuring the straightness and stability of the movement of the threaded slider 23.

[0025] Furthermore, during the movement of the threaded slider 23, the auxiliary fixing chain 215 slides on the guide sprocket 214 along with the movement of the threaded slider 23. The auxiliary fixing chain 215 further enhances the stability of the movement of the threaded slider 23 and prevents the threaded slider 23 from shaking or deviating during the movement.

[0026] like Figure 9 As shown, a feeding plate 40 is provided on the side of the heating furnace 1 away from the collecting plate 30. A feeding support leg 4 is fixedly connected to the bottom of the feeding plate 40, and a groove is provided at the center of the top of the feeding plate 40. The second fixed arm 6 is fixedly connected to another threaded slider 23. The feeding assembly also includes a second cover plate 61 fixedly connected to the bottom of the second fixed arm 6. A feeding motor 60 is fixedly installed on the top of the second fixed arm 6. The output end of the feeding motor 60 is fixedly connected to the material rack 62. The material rack 62 is slidably arranged inside the feeding tray 40. Slots are opened on both sides of the material rack 62. Furthermore, aluminum material is first added into the heating furnace 1. When there is no molten aluminum in the heating furnace 1, the aluminum material can be manually added into the heating furnace 1. When there is a large amount of molten aluminum in the heating furnace 1, the feeding assembly is used to drive the second fixed arm 6 to turn through the directional motor 28 until the feeding motor 60 is located at the center of the heating furnace 1. At this time, the second fixed arm 6 is driven to move down until the material rack 62 is immersed in the molten aluminum. At this time, the second cover plate 61 blocks the top opening of the heating furnace 1. At this time, the heating furnace 1 is driven to rotate, and the feeding motor 60 is started to drive until the material rack 62 reverses. The rotation direction between the heating furnace 1 and the material rack 62 is opposite. Furthermore, aluminum material is fed onto the feed rack 62 through the openings on both sides of the feed tray 40. The feed rack 62 has many filter holes, which can filter the molten aluminum. When the feed rack 62 carries the aluminum material and rotates in the opposite direction to the heating furnace 1, under the action of centrifugal force and the impact force of the molten aluminum, the aluminum material on the feed rack 62 is thrown out and falls into the heating furnace 1. At this time, the second cover plate 61 tightly covers the heating furnace 1, and no splashing occurs.

[0027] like Figures 7-8 As shown, the first fixed arm 5 is fixedly connected to one of the threaded sliders 23. The impurity removal and degassing assembly also includes a stirring motor 50 fixedly installed on the top of the first fixed arm 5. A hollow stirring rod 53 is fixedly installed at the output end of the stirring motor 50. A first cover plate 56 is installed at the bottom of the first fixed arm 5. An air inlet plate 55 rotatably connected to the hollow stirring rod 53 is fixedly installed at the bottom of the first cover plate 56. The air inlet pipe 51 is connected to the air inlet plate 55. The hollow stirring rod 53 is fixedly connected to the stirring blade 54, and the hollow stirring rod 53 and the stirring blade 54 are interconnected. A collection tray 30 is provided on one side of the heating furnace 1. Collection legs 3 are symmetrically fixedly connected to the bottom of the collection tray 30. A cleaning plate 57 is fixedly installed on the side of the first cover plate 56 near the collection legs 3. A cleaning baffle 58 is rotatably connected to the bottom of the cleaning plate 57. A limiting plate 510 is fixedly connected to one end of the cleaning baffle 58 extending to the outside of the cleaning plate 57. A limiting rod 59 is movably connected between the limiting plate 510 and the cleaning plate 57. Furthermore, aluminum alloys absorb gases such as hydrogen during the smelting process. If these gases cannot be discharged in time during solidification, they will form pores in the casting. In order to improve the refining quality, it is often necessary to add a de-purifying agent. At this time, the heating furnace 1 is driven to rotate. The de-purifying and degassing components are located above the heating furnace 1. The first fixed arm 5 is driven to move downward and drive the first cover plate 56 to cover the top of the heating furnace 1. At the same time, the stirring motor 50 installed on the top of the first fixed arm 5 is started. A hollow stirring rod 53 is fixedly installed at the output end of the stirring motor 50. The rotational power is transmitted to the hollow stirring rod 53 through the output end, causing the hollow stirring rod 53 to start rotating. Furthermore, since the hollow stirring rod 53 and the stirring blade 54 are fixedly connected and interconnected, the rotation of the hollow stirring rod 53 will drive the stirring blade 54 to rotate together. The stirring blade 54 rotates at high speed in the molten aluminum alloy liquid, stirring the aluminum liquid and causing strong convection motion in the aluminum liquid. The stirring direction of the stirring blade 54 is opposite to the rotation direction of the driving heating furnace 1. Furthermore, inert gas is introduced into the air inlet plate 55 through the air inlet pipe 51. The air inlet pipe 51 and the air inlet plate 55 are connected. The air inlet plate 55 is fixedly installed at the bottom of the first cover plate 56 and is rotatably connected to the hollow stirring rod 53. Therefore, the inert gas can enter the hollow stirring rod 53 through the air inlet pipe 51 and the air inlet plate 55 in sequence, and a purification agent is added into the feed pipe 52. Furthermore, the inert gas that enters the hollow stirring rod 53 flows into the stirring impeller 54 from the hollow stirring rod 53. As the stirring impeller 54 rotates at high speed in the aluminum liquid, the inert gas is evenly released into the aluminum liquid from the gas outlet on the stirring impeller 54. The inert gas forms a large number of tiny bubbles in the aluminum liquid. As these bubbles rise, they adsorb harmful gases such as hydrogen and impurity particles in the aluminum liquid and carry them to the surface of the aluminum liquid, thereby achieving the purpose of removing impurities and gas. Furthermore, during the switching process between the impurity removal and degassing components and the feeding component, some molten aluminum inevitably falls onto the heating furnace 1. At this time, the outer wall of the heating furnace 1 can be cleaned during the impurity removal and degassing process of the molten aluminum. The heating furnace 1 continues to rotate, and the aluminum slag on the heating furnace 1 is cleaned by the cleaning baffle 58. The impurities after cleaning fall onto the collection tray 30. At the same time, the tilt angle of the cleaning baffle 58 is set according to the different rotation directions of the heating furnace 1, so that the impurities can be completely discharged onto the collection tray 30 along the tilt angle of the cleaning baffle 58. Furthermore, when adjusting the tilt angle of the cleaning baffle 58, the cleaning plate 57 has many light holes, and the limiting plate 510 has a threaded hole. The limiting rod 59 is threadedly connected to the limiting plate 510, and the limiting rod 59 slides relative to the light hole. At this time, by taking out the limiting rod 59, aligning the threaded hole with any light hole, and then inserting the limiting rod 59, the adjustment of the tilt angle of the cleaning baffle 58 is completed.

[0028] In this embodiment, during the alternating operation of the feeding assembly and the impurity removal and degassing assembly, the feed rack 62 of the feeding assembly has many filter holes. These filter holes can filter the aluminum liquid, so the feed rack 62 can collect the slag on the inner surface of the heating furnace 1. Then the feed rack 62 is moved to the feed inlets on both sides of the feed plate 40, and the workers use rakes to clean out the slag. Since the heating furnace 1 has a notch, the notch needs to be aligned with the feed plate 40 by a position sensor to ensure that the feed rack 62 can smoothly enter the inner side of the heating furnace 1.

[0029] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
