Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy manufacturing technology, and in particular to a novel aluminum alloy melt purification device. Background Technology

[0002] Aluminum alloy melt purification equipment is a key device used to remove dissolved hydrogen (H2) and non-metallic inclusions (such as oxides of Al2O3 and MgO, flux, and furnace lining fragments) from molten aluminum. The purpose is to improve the metallurgical quality of the final casting or ingot (such as reducing porosity and looseness, and improving density, mechanical properties and surface quality). Gas purification method is usually used to purify aluminum alloy melt.

[0003] Traditional equipment typically employs gas purification or filter purification methods. However, traditional equipment only uses a single method to purify aluminum alloy melts. A single method is insufficient to purify multiple impurities, and the purification is incomplete. Equipment transfer is required to achieve purification using multiple methods, which is complex and cumbersome, hindering the needs of rapid production. Furthermore, it is difficult to ensure sufficient contact between the melt, the filter, and the inert gas used in the purification process, resulting in incomplete purification and a long purification time, which is also detrimental to rapid production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel aluminum alloy melt purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel aluminum alloy melt purification device includes a cylinder and a vertical plate fixedly connected to one side of the cylinder. A motor and a gas tank are fixedly mounted on the vertical plate. A first rotating shaft rotatably passes through the vertical plate. The first rotating shaft and the output end of the motor are connected via a pulley assembly. A gas supply pipe is fixedly connected to one side of the gas tank. One end of the gas supply pipe is rotatably connected to the first rotating shaft. A cam is fixedly connected to the lower side of the first rotating shaft. A second rotating shaft rotatably passes through the cam. A connecting pipe is fixedly connected to one side of the first rotating shaft. One end of the connecting pipe is rotatably connected to the second rotating shaft. Multiple gas inlets are fixedly connected to the second rotating shaft.

[0007] Preferably, a fixed circular plate is fixedly connected to the cylinder, and an annular rail and an annular groove are formed on the fixed circular plate. The annular rail and the cam are slidably connected. The second rotating shaft rotates through the annular groove. A first gear is fixedly connected to the second rotating shaft, and a second gear is rotatably connected to the cam. The first gear and the second gear mesh with each other. A ring tooth is fixedly connected to the cylinder, and the ring tooth meshes with the second gear.

[0008] Preferably, a fixed circular tooth is fixedly connected to the inner wall of the cylinder, a stirring rod is rotatably connected to the lower side of the second rotating shaft, and a third gear is fixedly connected to the lower side of the stirring rod, the third gear meshing with the fixed circular tooth.

[0009] Preferably, a plurality of connecting rods are fixedly connected to one side of the second rotating shaft, and a filter is rotatably connected to the connecting rods.

[0010] Preferably, a heat-insulating foam pad is fixedly installed at the bottom of the cylinder.

[0011] Preferably, a pressure pump is fixedly connected to the gas tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model adopts a combination of gas purification method and filter purification method. A single device uses both methods in combination to quickly and efficiently purify aluminum alloy melt. The motor drives the synchronous rotation of the filter and the air inlet, and the external gas tank injects inert gas for purification. The two purification processes are carried out simultaneously. The operation is simple and the process is convenient, which is conducive to meeting the needs of rapid production.

[0014] 2. Furthermore, the two purification methods work together. With the rotation of the first shaft, the cam rotates along the ring rail, which drives the second gear to rotate along the ring teeth. The second gear then drives the first gear to rotate, which in turn drives the second shaft to rotate. This allows the filter and the air inlet to rotate synchronously, ensuring that the filter and the inert gas can fully contact the molten aluminum alloy. This also allows the inert gas to fully contact the molten aluminum alloy, thus enabling both purification methods to function effectively and meet the requirements of rapid purification and efficient production.

[0019] Reference Figures 1-3 A novel aluminum alloy melt purification device includes a cylindrical cylinder 1 and a vertical plate 2 fixedly connected to one side of the cylinder 1. The vertical plate 2 is used to fix a motor 4 and a gas tank 5. A heat-insulating foam gasket is fixedly installed at the bottom of the cylinder 1 to prevent the melt inside the cylinder 1 from overheating and affecting other components, thus providing heat insulation protection for other components. The motor 4 and the gas tank 5 are fixedly installed on the vertical plate 2. The gas tank 5 stores high-purity inert gases, such as nitrogen and argon. The inert gases will not react with the aluminum alloy melt, but can fully contact with other gases inside and carry them out, thereby achieving an effective purification effect on the aluminum alloy melt. A pressure pump 6 is fixedly connected to the gas tank 5. The pressure pump 6 increases the pressure inside the gas tank 5 by pressurizing, facilitating the discharge of inert gases through a gas delivery pipe 7, a connecting pipe 15, and a gas inlet 19. Within the aluminum alloy melt, a first rotating shaft 9 is rotatably connected to the vertical plate 2. The first rotating shaft 9 and the output end of the motor 4 are connected via a pulley assembly 8. The pulley assembly 8 consists of a belt, a hub, a rim, and spokes. The hub is directly mounted on the rotating shaft to ensure synchronous rotation and transmit torque. The rim guides the belt, and the spokes are the supporting parts connecting the hub and the rim. The whole assembly is used to transmit the movement between the rotating shafts. A gas supply pipe 7 is fixedly connected to one side of the gas tank 5. One end of the gas supply pipe 7 is rotatably connected to the first rotating shaft 9. A cam 14 is fixedly connected to the lower side of the first rotating shaft 9. A second rotating shaft 18 is rotatably connected to the cam 14. A connecting pipe 15 is fixedly connected to one side of the first rotating shaft 9. One end of the connecting pipe 15 is rotatably connected to the second rotating shaft 18. Multiple air inlets 19 are fixedly connected to the second rotating shaft 18.

[0020] A fixed circular plate 10 is fixedly connected to the cylinder 1. The fixed circular plate 10 has an annular rail 12 and an annular groove 11. The annular rail 12 and the cam 14 are slidably connected. The second rotating shaft 18 rotates through the annular groove 11. A first gear 16 is fixedly connected to the second rotating shaft 18. A second gear 17 is rotatably connected to the cam 14. The first gear 16 and the second gear 17 mesh with each other. A ring tooth 13 is fixedly connected to the cylinder 1. The ring tooth 13 meshes with the second gear 17. Under the rotation of the first rotating shaft 9, the cam 14 rotates along the annular rail 12, which drives the second gear 17 to rotate along the ring tooth 13. The second gear 17 then drives the first gear 16 to rotate, which in turn drives the second rotating shaft 18 to rotate. This causes the filter 21 and the air inlet 19 to rotate synchronously, allowing the filter 21 to fully contact the molten aluminum alloy and the inert gas to fully contact the molten aluminum alloy. This allows both purification methods to work effectively, achieving the requirements of rapid purification and efficient production.

[0021] A fixed circular tooth 3 is fixedly connected to the inner wall of the cylinder 1. A stirring rod 22 is rotatably connected to the lower side of the second rotating shaft 18. A third gear 23 is fixedly connected to the lower side of the stirring rod 22. The third gear 23 meshes with the fixed circular tooth 3. Multiple connecting rods 20 are fixedly connected to one side of the second rotating shaft 18. A filter 21 is rotatably connected to the connecting rod 20. The melt is stirred to make it fully contact the filter 21 and the inert gas. The melt flows through the ceramic filter 21, which is made of materials such as alumina or silicon carbide and has a three-dimensional network porous structure. The filter 21 captures inclusions of different sizes through three mechanisms: direct interception, deep adsorption, and cake effect. This is existing technology and will not be described in detail.

[0022] In this invention, when the aluminum alloy melt needs to be purified, the motor 4 and the air pump 6 are started. The output of the motor 4 drives the first rotating shaft 9 to rotate via the pulley assembly 8. The first rotating shaft 9 drives the cam 14 to rotate along the ring rail 12. The cam 14 drives the second rotating shaft 18 to rotate around the first rotating shaft 9. The cam 14 drives the second gear 17 to rotate along the ring gear 13. The second gear 17 drives the first gear 16 to rotate. The first gear 16 drives the second rotating shaft 18 to rotate around the first rotating shaft 9 while simultaneously rotating on its own axis. The second rotating shaft 18 drives the air inlet 19 and the connecting rod 20 to rotate. The connecting rod 20 drives the filter 21 to rotate around the second rotating shaft 18. The filter 21 also rotates on the connecting rod 20, thus allowing the filter 21 to rotate with the air inlet 19 and the connecting rod 20. The aluminum alloy molten material is in full contact to achieve a thorough purification effect. While the second rotating shaft 18 rotates around the first rotating shaft 9, it drives the third gear 23 to rotate along the fixed circular teeth 3. The third gear 23 drives the stirring rod 22 to rotate, stirring the aluminum alloy molten material and ensuring it is in full contact with the filter 21 and the inert gas. At the same time, the air pressure pump 6 pressurizes the inert gas in the gas tank 5 and delivers it through the gas supply pipe 7 to the pipe inside the first rotating shaft 9. Then, through the connecting pipe 15, the inert gas in the pipe inside the first rotating shaft 9 is delivered to the pipe inside the second rotating shaft 18. Finally, through the air inlet 19, the inert gas in the pipe inside the second rotating shaft 18 is discharged into the aluminum alloy molten material inside the cylinder 1, adsorbing and discharging other gases in the molten material to achieve a purification effect.
