[0001] This utility model relates to the technical field of aluminum alloy processing equipment, and in particular to an aluminum alloy liquid degassing and stirring device. Background Technology

[0002] Molten aluminum alloy is a liquid alloy formed by melting and mixing aluminum with other metals (such as silicon, magnesium, copper, etc.). It is lightweight, high-strength, corrosion-resistant, and has excellent casting properties. Its melting point is usually between 580℃ and 750℃. It has good fluidity, is easy to fill complex molds, and is widely used in the automotive, aerospace, electronics, and construction industries.

[0003] Existing equipment tends to generate large bubbles during stirring, leading to uneven gas output. Furthermore, it may create eddy dead zones when stirring molten aluminum alloy, resulting in incomplete stirring and reduced stirring efficiency. Prolonged stirring may also cause the temperature of the molten aluminum alloy to drop, affecting product quality and thus reducing its practicality. Utility Model Content

[0021] 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.

[0022] Example 1

[0023] Reference Figure 1-4 An aluminum alloy liquid degassing and stirring device includes a circular cover 1. A motor mounting bracket 2 is fixedly connected to the middle position of the upper surface of the circular cover 1. A drive motor 3 is installed inside the motor mounting bracket 2. A drive rod 4 is installed at the power output end of the drive motor 3. A connecting column 5 is fixedly connected to the lower surface of the drive rod 4. A circular rod 6 is fixedly connected to the lower surface of the connecting column 5. Three stirring plates 7 are fixedly connected to the outer surface of the circular rod 6. Stirring plates 9 are fixedly connected to the lower surface of the three stirring plates 7 away from the circular rod 6 through a connecting stirring column 8.

[0024] A circular sleeve 10 is provided on the lower surface of the circular rod 6. A circular rod 11 is provided on the lower surface of the circular sleeve 10. Five stirring plates 12 are fixedly connected to the middle and bottom positions of the outer surface of the circular rod 11. Four extended stirring columns 13 are fixedly connected to the upper surface of the five stirring plates 12. A reverse rotation assembly 14 is provided inside the circular sleeve 10. The three stirring plates 7 fixed to the outer surface of the circular rod 6 stir the aluminum alloy liquid under the action of the circular rod 6. The stirring plates 7 are connected to the stirring plates 9 through the stirring columns 8, so that the stirring plates 9 also participate in the stirring process. The combination of stirring plates 7 and 9 expands the stirring range and increases the stirring force, so that the upper part of the aluminum alloy liquid in the stirring tank 29 is fully stirred. The five stirring plates 12 fixed to the middle and bottom positions of the outer surface of the circular rod 11, and the four extended stirring columns 13 fixed to the upper surface of the stirring plates 12, stir the lower part of the aluminum alloy liquid. The addition of stirring plate 3 12 and extended stirring column 13 further expands the stirring area, allowing the aluminum alloy liquid to be stirred in all parts of the stirring tank 29, thus improving the uniformity of stirring.

[0025] The reverse rotation assembly 14 includes a connecting rod 15, a bevel gear 16 fixedly connected to the lower surface of the connecting rod 15, a bevel gear 17 meshing with the outer surface of the bevel gear 16, and a bevel gear 18 meshing with the lower surface of the outer surface of the bevel gear 17. The reverse rotation assembly 14 inside the circular sleeve 10 enables the circular rod 11 to rotate in opposite directions to the circular rod 16. When the drive rod 4 rotates, it drives the connecting rod 15 to rotate, and the bevel gear 16 fixed to the lower surface of the connecting rod 15 also rotates accordingly. The bevel gear 16 meshes with the bevel gear 17, transmitting power to the bevel gear 17, causing it to rotate around the shaft 20 located on the inner wall of the circular sleeve 10. The bevel gear 17 then meshes with the bevel gear 18, thereby driving the bevel gear 18 to rotate. Since the bevel gear 318 is fixedly connected to the circular rod 21 through the connecting rod 321, the rotation of the circular rod 21 is finally realized, and the direction of rotation is opposite to that of the circular rod 16.

[0026] A connecting rod 19 is fixedly connected to the middle position behind the second bevel gear 17. A rotating shaft 20 is located behind the connecting rod 19 and is situated on the inner wall of the circular sleeve 10. A connecting rod 21 is fixedly connected below the third bevel gear 18, and the lower surface of the connecting rod 21 is fixedly connected to the upper surface of the second circular rod 11. The connecting rod 19 is fixed at the middle position behind the second bevel gear 17, while the rotating shaft 20 behind the connecting rod 19 is located on the inner wall of the circular sleeve 10. The rotating shaft 20 provides a rotational support point for the connecting rod 19 and the connected second bevel gear 17. When the first bevel gear 16 rotates and drives the second bevel gear 17, the connecting rod 19 can rotate around the rotating shaft 20, thereby transmitting the power of the first bevel gear 16 to the second bevel gear 17, ensuring the stability and continuity of the power transmission process.

[0027] A mixing tank 29 is located below the circular cover 1. A heating sleeve 22 is installed on the outer surface of the mixing tank 29. A heating tube 23 is installed inside the heating sleeve 22, and an insulation plate 24 is installed on the outside of the heating tube 23. The insulation plate 24 on the outside of the heating tube 23 has good heat preservation performance. The insulation plate 24 is usually made of a material with low thermal conductivity, such as rock wool or polyurethane foam. These materials can effectively prevent heat from being lost from the heating tube 23 and the mixing tank 29 to the outside. When the heat generated by the heating tube 23 is transferred to the insulation plate 24, the heat conduction speed in the insulation plate 24 is very slow due to its low thermal conductivity, thereby reducing heat loss. The presence of the insulation plate 24 allows the temperature inside the mixing tank 29 to remain relatively stable. During the mixing and degassing process, a stable temperature environment is crucial to ensuring the quality of the aluminum alloy liquid. Without the insulation plate 24, heat would be lost rapidly, causing the temperature inside the mixing tank 29 to drop, the fluidity of the aluminum alloy liquid to deteriorate, and affecting the mixing and degassing effect. The insulation board 24 can effectively maintain temperature stability, improve energy efficiency, and reduce operating costs;

[0028] A discharge pipe 25 is fixedly connected to the lower part of the outer surface of the mixing tank 29. A load-bearing plate 26 is fixedly connected to the lower surface of the mixing tank 29, and a support frame 27 is fixedly connected to the lower part of the load-bearing plate 26. The discharge pipe 25 is fixed to the lower part of the outer surface of the mixing tank 29. After the aluminum alloy liquid completes the mixing and degassing processes in the mixing tank 29, it will naturally gather at the bottom of the mixing tank 29 due to gravity. At this time, the aluminum alloy liquid will flow out of the mixing tank 29 through the discharge pipe 25 under its own gravity, realizing the discharge process.

[0029] A feed pipe 30 is fixedly connected to the outer surface of the circular cover 1, and a venting pipe 31 is fixedly connected to the upper surface of the circular cover 1. The feed pipe 30, fixed to the outer surface of the circular cover 1, primarily provides a convenient feeding channel for the mixing tank 29. During the degassing and mixing of the aluminum alloy liquid, aluminum alloy raw materials need to be added to the mixing tank 29. Through the feed pipe 30, the operator can directly transport the aluminum alloy raw materials from the outside to the inside of the mixing tank 29 without opening the circular cover 1.

[0030] The existing equipment tends to generate large bubbles during stirring, resulting in uneven gas output. Furthermore, when stirring molten aluminum alloy, it may create eddy dead zones, leading to incomplete stirring and reduced stirring efficiency. In addition, prolonged stirring may cause the temperature of the molten aluminum alloy to drop, affecting product quality and thus reducing its practicality.

[0031] The aluminum alloy liquid to be treated is added into the mixing tank 29 through the feed pipe 30. The heating tube 23 in the heating sleeve 22 is activated to heat the aluminum alloy liquid in the mixing tank 29 to a suitable processing temperature. At the same time, the insulation plate 24 begins to function, reducing heat loss and maintaining temperature stability. The drive motor 3 is turned on, and the power output end of the drive motor 3 drives the drive rod 4 to rotate, which in turn drives the connecting rod 15 and the bevel gear 16. The rotation of the drive rod 4 directly drives the connected connecting rod 15 to rotate, and the connecting rod 15 in turn drives the bevel gear 16 fixedly connected to its lower surface to rotate synchronously. The bevel gear 16 drives the bevel gear 17. The rotating bevel gear 16 and the bevel gear 17 mesh with each other. According to the bevel gear transmission principle, the rotation of the bevel gear 16 causes the bevel gear 17 to start rotating. Since the connecting rod 219 is fixed at the middle position behind the bevel gear 217, and the connecting rod 219 is connected to the inner wall of the circular sleeve 10 through the rotating shaft 20, the bevel gear 217 rotates around the rotating shaft 20. The lower surface of the rotating bevel gear 217 meshes with the bevel gear 318, thereby driving the bevel gear 318 to rotate. The connecting rod 321, which is fixedly connected to the lower part of the bevel gear 318, rotates together with the bevel gear 318. Since the lower surface of the connecting rod 321 is fixedly connected to the upper surface of the circular rod 21, the circular rod 21 begins to rotate. Furthermore, due to the transmission of the conical gears twice, the rotation direction of the second circular rod 11 is opposite to that of the first circular rod 6. When the drive rod 4 rotates, it drives the first circular rod 6 to rotate through the connecting column 5. The three stirring plates 7 on the outer surface of the first circular rod 6 and the stirring plate 9 connected to them stir the aluminum alloy liquid. The rotating circular rod 11 drives the five stirring plates 12 at the middle and bottom positions of its outer surface and the four extended stirring columns 13 on the upper surface of the stirring plates 12 to stir the aluminum alloy liquid in the opposite direction. The opposite rotation of the first circular rod 6 and the second circular rod 11 causes convection and turbulence in the aluminum alloy liquid, breaking the dead flow that may be formed by stirring in one direction, and making the aluminum alloy liquid fully mixed in the mixing tank 29. During the stirring process, the gas in the aluminum alloy liquid is more likely to gather to form bubbles and rise to the surface. The gas diffuser 31 promptly discharges the escaped gas out of the mixing tank 29.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
