[0001] This utility model relates to the field of aluminum alloy plate production technology, specifically to a raw material mixing device for aluminum alloy plate production. Background Technology
[0002] Aluminum alloys, as a lightweight and high-strength metallic material, are widely used in aerospace, automotive manufacturing, construction, and other fields. To ensure the performance and stability of aluminum alloy products, the mixing process is crucial. The general flow of the powder metallurgy process for producing aluminum alloy sheets includes: powder preparation, compaction, sintering (including hot isostatic pressing, cold isostatic pressing, etc.), forging, and finishing.
[0003] In the powder production process, various powders need to be uniformly mixed. Current mixing devices mostly employ vertical or horizontal mechanical agitators. However, due to the high bulk density and weight of metal powders, mechanical agitation makes it difficult to achieve uniform mixing, thus affecting the quality of the produced aluminum alloy sheets. Therefore, this paper proposes a raw material mixing device for aluminum alloy sheet production. Utility Model Content

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0026] Example 1
[0027] Existing powder mixing equipment mostly employs vertical or horizontal mechanical agitation. Due to the high bulk density and heavy weight of powders, it is difficult to achieve uniform mixing. Therefore, this embodiment provides a raw material mixing device for aluminum alloy plate production, such as... Figures 1-4 As shown.
[0028] The mixing equipment includes a frame 1, on which an airflow pipe 2 and a connecting pipe 6 are horizontally mounted. The airflow pipe 2 is positioned higher than the connecting pipe 6. A premixing chamber 5 is vertically connected between the airflow pipe 2 and the connecting pipe 6. The premixing chamber 5 contains a premixing component 9 for initially agitating various raw materials. Several sets of storage silos 3 are installed side by side on the top of the frame 1. The storage silos 3 can temporarily store powders, such as aluminum powder, copper powder, iron powder, molybdenum powder, cobalt powder, etc. The appropriate powder can be loaded into each storage silo 3 according to the performance requirements of the aluminum alloy plate. The feed pipe of the storage silo 3 extends downward into the airflow pipe 2, and the feed pipe is equipped with a solenoid valve 4 to control the feeding speed. The feeding speed of the feed pipe is controlled by controlling the solenoid valve 4. A mixing component 7 is provided at the end of the connecting pipe 6 away from the premixing chamber 5. The mixing component 7 includes a mixing chamber 71, in which a first distribution pipe 72 and a second distribution pipe 73 are installed opposite each other. The other ends of the first distribution pipe 72 and the second distribution pipe 73 extend out of the mixing chamber 71 and are connected to the connecting pipe 6. During production, a high-speed airflow is introduced into the airflow pipe 2. The powder flowing out of the storage silo 3 falls into the airflow pipe 2 and enters the premixing chamber 5 along with the airflow. After preliminary mixing by the premixing component 9, a premix is formed. The premix continues to flow through the connecting pipe 6 and is eventually divided into two streams. One stream enters the first distribution pipe 72, and the other enters the second distribution pipe 73. The two high-speed flowing powder streams collide relative to each other in the mixing chamber 71 and are mixed again to form a mixture. By using a premixing + mixing method, the mixing effect of each raw material is improved, and continuous mixing can be achieved, thereby improving production efficiency.
[0029] Furthermore, the junction of the first distribution pipe 72, the second distribution pipe 73, and the connecting pipe 6 is Y-shaped to evenly divide the premixed material sprayed from the connecting pipe 6 into two streams.
[0030] Specifically, the premixing component 9 includes a base plate 91 fixed inside the premixing chamber 5. A rotating shaft 92 is rotatably mounted on the base plate 91, and several sets of stirring rods 93 are fixed from top to bottom on the rotating shaft 92. A servo motor 94 that drives the rotating shaft 92 to rotate is also mounted on the base plate 91. Various powders flowing out from the airflow pipe 2 enter the premixing chamber 5 together. At this time, the servo motor 94 is started, driving the rotating shaft 92 and the stirring rods 93 on it to rotate, thus dispersing and mixing the various powders, achieving preliminary mixing of the various powders. It has the characteristics of simple structure, convenience and high efficiency.
[0031] To separate the mixture in the airflow, a separator 8 is installed at the bottom of the mixing chamber 71. This separator includes a temporary storage box 81 with several sets of exhaust ports 83. The temporary storage box 81 has a side door (not shown in the figure). A guide pipe 84 is installed through the top of the temporary storage box 81. The top end of the guide pipe 84 extends upwards and connects to the bottom of the mixing chamber 71, while the bottom end of the guide pipe 84 extends downwards and connects to a filter bag 82. The mixture and airflow enter the guide pipe 84 from the bottom of the mixing chamber 71, and then enter the filter bag 82 together. The mixture is trapped in the filter bag 82, while the airflow passes through the filter bag 82 into the temporary storage box 81, and finally exits from the exhaust ports 83, thus achieving the separation and collection of the mixture.
[0032] This equipment integrates and continuously processes the premixing, mixing, separation, and collection of various powders, thereby improving the mixing effect and production efficiency of the powders.
[0033] Example 2
[0034] This is basically the same as Example 1, except that premix 9 is replaced with premix 10, such as... Figures 5-6 As shown, the premixing component 10 includes several sets of funnels 101 fixed vertically. A conical block 102 is fixed to the bottom of each funnel 101 via a connecting rod 103. The tip of the conical block 102 extends into a leak hole at the bottom of the funnel 101, but does not completely block the leak hole, ensuring that powder can leak out. The sidewall of the funnel 101 is fixed to the inner wall of the premixing chamber 5, and the edge of the conical block 102 does not contact the inner wall of the premixing chamber 5. Various powders flowing out of the airflow pipe 2 enter the premixing chamber 5 together, and under the action of wind and gravity, they concentrate into the funnel 101, finally leaking out through the leak hole and being dispersed in all directions by the conical block 102, achieving a concentration + dispersion function. By repeating the concentration + dispersion process multiple times, premixing of the powder can be achieved. Compared to the premixing component 9 in Example 1, the structure is simpler.
[0035] 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.
