[0002] Aluminum is a silvery-white metal, the third most abundant metal in the Earth's crust after oxygen and silicon. In the preparation of aluminum ingots, suitable aluminum alloy raw materials are selected. These raw materials can be aluminum alloy ingots or recycled aluminum materials. The raw materials are added to a melting furnace, which usually uses electric heating or flame heating to heat the aluminum material above its melting point to melt it. The molten aluminum is then poured into a mold and cooled to form the aluminum ingot.

[0003] If impurities in molten aluminum are not effectively removed by filtration, they will form defects such as pores and inclusions in aluminum products. These defects will not only reduce the mechanical properties of aluminum products, such as tensile strength and yield strength, but may also affect their appearance quality and processing performance. These impurities are generally removed by skimming, but this method is carried out directly in the melting furnace and cannot ensure that the impurities can be completely cleaned. Therefore, this utility model provides an aluminum ingot processing and forming device. Utility Model Content

The inner wall of the filter tube is provided with a threaded groove, and a threaded pipe is threadedly connected to the inner wall of the threaded groove. The threaded pipes on both sides are respectively fixedly connected to an outlet pipe and a bottom pipe. One end of the outlet pipe is fixedly connected to the outlet of the melting furnace, and the bottom end of the bottom pipe is fixedly connected to a casting gun. A filter plate is slidably connected to the inner wall of the filter tube. The filter plate is used to filter impurities in the aluminum liquid before casting. The outer wall of the filter tube drives a rotating plate to rotate through a driving mechanism. The outer wall of the rotating plate is provided with a reciprocating mechanism for striking the filter plate to prevent the filter plate from being blocked by impurities and affecting the casting effect.

One end of the reciprocating rod is fixedly connected to a striking plate. A fixing ring is fixedly connected to the inner wall of the filter tube. The fixing ring is connected to the filter plate through an elastic component, and a support plate is fixedly connected to the outer wall of the fixing plate. The reciprocating rod passes through the support plate and can slide relative to the support plate. The elastic component includes a spring, and the two ends of the spring are fixedly connected to the opposite sides of the fixing ring and the filter plate, respectively.

[0007] Preferably, the drive mechanism includes a motor, the outer wall of which is fixedly connected to the outer wall of the filter tube. One end of the motor output shaft is fixedly connected to a transmission shaft via a coupling.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-7 An aluminum ingot processing and forming device includes a melting furnace 1 and a filter tube 2. The melting furnace 1 is the core part of the aluminum ingot processing and forming device, used to heat the aluminum material to above its melting point and melt it. This is existing technology. The inner wall of the filter tube 2 has a threaded groove 3, and a threaded tube 4 is threadedly connected to the inner wall of the threaded groove 3. The design of the threaded groove 3 and the threaded tube 4 enhances the connection stability and sealing of the device, and facilitates the disassembly and installation of the filter tube 2. The two threaded tubes 4 are respectively fixedly connected to an outlet pipe 5 and a bottom pipe 6. One end of the outlet pipe 5 is fixedly connected to the outlet of the melting furnace 1, and the bottom end of the bottom pipe 6 is fixedly connected to a casting gun. The outlet pipe 5 guides the molten aluminum in the melting furnace 1 into the filter tube 2, and the bottom pipe 6 transports the filtered molten aluminum to the casting gun. A filter plate 7 is slidably connected to the inner wall of the filter tube 2. The filter plate 7 is made of a metal plate with openings for the flow of molten aluminum, used to filter impurities in the molten aluminum before casting, thereby improving the quality of the aluminum ingot. The filter plate 7 is used for... Before casting, impurities in the molten aluminum are filtered out. The outer wall of the filter tube 2 is driven by a rotating plate 8 to rotate. The outer wall of the rotating plate 8 is equipped with a reciprocating mechanism to strike the filter plate 7, preventing the filter plate 7 from being blocked by impurities and affecting the casting effect. All structures in the filter tube 2 are made of high-temperature resistant materials and will not be affected by the high temperature of the molten aluminum. By setting up the filter tube 2, impurities in the molten aluminum are blocked by the filter plate 7. Every once in a while, the motor 15 is started to push the reciprocating rod 10 forward, and the striking plate 11 contacts the filter plate 7 to strike the filter plate 7, which can knock out the impurities blocked in the filter holes of the filter plate 7. If impurities accumulate in the filter tube 2 for a long time, the filter tube 2 can be removed from the liquid outlet pipe 6 and the liquid outlet pipe 5 for cleaning and maintenance. This not only effectively removes impurities in the molten aluminum, but also prevents the filter plate 7 from being blocked by impurities and affecting the casting effect, effectively avoiding defects such as pores and inclusions in aluminum products.

[0020] Please see Figure 4-6The reciprocating mechanism includes an inclined rotating ring 9, one side of which is fixedly connected to one side of the rotating plate 8. A reciprocating rod 10 is slidably connected to the outer wall of the inclined rotating ring 9. The inclined rotating ring 9 and the reciprocating rod 10 will not separate. During the process from the lowest point of the inclined rotating ring 9 contacting the reciprocating rod 10 to the highest point of the inclined rotating ring 9 contacting the reciprocating rod 10, the reciprocating rod 10 will be pushed forward. Subsequently, the inclined rotating ring 9 continues to rotate, which will drive the reciprocating rod 10 to move backward. A striking plate 11 is fixedly connected to one end of the reciprocating rod 10. The striking plate 11 is located inside the filter tube 2 near the liquid outlet pipe 5. Therefore, when the filter plate 7 is struck, due to inertia, impurities on the filter tube 2 will fall into the filter tube 8. Near the outlet pipe 5, a fixing ring 12 is fixedly connected to the inner wall of the filter pipe 2. The fixing ring 12 is connected to the filter plate 7 through an elastic component, and a support plate 13 is fixedly connected to the outer wall of the fixing plate. The reciprocating rod 10 passes through the support plate 13 and can slide relative to the support plate 13. The elastic component includes a spring 14, and the two ends of the spring 14 are fixedly connected to the opposite sides of the fixing ring 12 and the filter plate 7, respectively. The design of the reciprocating mechanism ensures the continuous unobstructed flow of the filter plate 7, avoids pouring interruption and aluminum ingot quality degradation caused by blockage, and extends the service life of the filter plate 7 while ensuring the effectiveness and stability of the striking mechanism.

[0021] Please see Figure 2-4 and Figure 7 The drive mechanism includes a motor 15, which is connected to an external power source and is a three-phase asynchronous motor. The outer wall of the motor 15 is fixedly connected to the outer wall of the filter tube 2. One end of the output shaft of the motor 15 is fixedly connected to a transmission shaft 16 via a coupling. The outer wall of the transmission shaft 16 drives the rotating shaft 17 to rotate via a transmission assembly. One end of the rotating shaft 17 is fixedly connected to one side of the rotating plate 8. A connecting plate 18 is fixedly connected to the top of the inner cavity of the filter tube 2, and one end of the rotating shaft 17 is rotatably connected to one side of the connecting plate 18. The outer wall of the filter tube 2 is connected to the transmission assembly via a sealing assembly. The transmission assembly includes a transmission wheel 19, which is fixedly connected to the outer walls of both the transmission shaft 16 and the rotating shaft 17. The two transmission wheels 19 are connected by a transmission belt 20, which is made of a high-temperature resistant material. The sealing assembly includes a sealing plate 21, which penetrates the filter tube 2 and is fixedly connected to it. The transmission belt 20 penetrates the sealing plate 21 and is slidably connected to it. The sealing assembly is used to ensure the sealing performance of the transmission assembly when it penetrates the filter tube 2, preventing aluminum liquid leakage.

[0022] In use, aluminum alloy raw materials are placed in melting furnace 1 and heated. Melting furnace 1 can be an electric arc furnace, induction furnace, or other types of melting furnace. The molten aluminum is filtered through filter pipe 2. The filtered molten aluminum is then injected into the mold through the liquid outlet pipe 6 and the casting gun. Impurities in the molten aluminum are blocked by filter plate 7 after passing through filter pipe 2. At regular intervals, motor 15 is started, driving drive shaft 16 to rotate. Drive shaft 16 drives drive wheel 19 connected to it to rotate. Drive wheel 19, via drive belt 20, drives drive wheel 19 connected to rotating shaft 17 to rotate. Rotating shaft 17 then drives rotating plate 8 to rotate, which in turn drives inclined rotating ring 9 to rotate. Inclined rotating ring 9 moves linearly along reciprocating rod 10. During the process from the lowest point of the rotating ring 9 contacting the reciprocating rod 10 to the highest point of the inclined rotating ring 9 contacting the reciprocating rod 10, the reciprocating rod 10 will be pushed forward. The reciprocating rod 10 will drive the striking plate 11 to move synchronously. The striking plate 11 will contact the filter plate 7 and strike the filter plate 7, which will knock out the impurities blocking the filter holes of the filter plate 7. At the same time, the filter plate 7 will drive the spring 14 to stretch. Then the inclined rotating ring 9 will continue to rotate and the striking plate 11 will move backward until it no longer contacts the filter plate 7. The filter plate 7 will return to its original position due to the reciprocating property of the spring 14, and then the next strike will be performed. If impurities accumulate in the filter tube 2 for a long time, the filter tube 2 can be removed from the lower liquid pipe 6 and the outlet liquid pipe 5 for cleaning and maintenance.
