[0002] Aluminum ingots are mainly used in the smelting, processing, casting and melting of aluminum. They are the basic raw materials for manufacturing aluminum materials, aluminum alloys and other aluminum products. In the production process, bauxite is pre-treated by crushing, grinding, screening, ore washing, roasting, etc. to obtain alumina, which is then produced by electrolysis to obtain molten aluminum, and finally passed through a casting mold and cooled to form aluminum ingots.

[0003] In the existing aluminum liquid stirring device for aluminum ingot production, such as the Chinese utility model patent with publication number CN206676332U, entitled A lifting type aerated stirring device for aluminum liquid stirring, the blower directly connects the air through a hose to the movable structure composed of a sleeve and a snap block. The connection structure is not stable enough and is easily damaged in a high temperature environment. At the same time, the layout of the stirring, lifting and blowing mechanisms is unreasonable, and many structures of the three overlap or pass through each other. Not only is the installation and maintenance cost high, but the probability of mutual influence during use causing failure is also high. Therefore, it is necessary to design an aluminum liquid stirring device for aluminum ingot production to address the above problems. Utility Model Content

[0011] Preferably, the stabilizing sleeve is slidably connected to the vertical portion of the mounting bracket, and the vertical portion of the mounting bracket and the stabilizing sleeve are both rectangular in top view.

[0012] Preferably, a positioning plate is fixedly installed on the inner side of the vertical portion of the support plate, and the positioning plate is connected and fixed to the bottom of the outer wall of the movable sleeve.

[0030] See also Figure 1-4 , an embodiment provided by the utility model:

[0031] An aluminum liquid stirring device for aluminum ingot production, comprising:

[0032] An aluminum liquid tank 1, a guide channel 2 is opened on one side of the aluminum liquid tank 1, a mounting bracket 3 is fixed on the outer side of the back of the aluminum liquid tank 1, a first servo motor 4 is fixedly mounted on the top of the mounting bracket 3, and a vertical threaded rod 5 is installed on the output end of the bottom of the first servo motor 4;

[0033] A vertical threaded rod 5 is provided with a movable sleeve 6 on the top of the vertical threaded rod 5. The vertical threaded rod 5 is threadedly connected to the movable sleeve 6. The horizontal plane where the bottom end of the movable sleeve 6 is located is higher than the horizontal plane where the bottom end of the stirring rod 14 is located. The above structural design enables the vertical threaded rod 5 to use the threaded connection relationship to drive the movable sleeve 6 to move vertically with the support plate 8 and the stirring rod 14, and ensure that the stirring rod 14 can extend into the aluminum liquid to a sufficient depth. The bottom of the outer wall of one side of the movable sleeve 6 is connected and fixed to one side of the stabilizing sleeve 7. The stabilizing sleeve 7 is installed on the vertical part of the mounting bracket 3. The stabilizing sleeve 7 and the vertical part of the mounting bracket 3 are slidably connected. Next, the top-view cross-sectional shapes of the vertical part of the mounting bracket 3 and the stabilizing sleeve 7 are both rectangular. The above-mentioned structural design can prevent the movable sleeve 6 from rotating with the vertical threaded rod 5, ensuring that the movable sleeve 6 can only move vertically along the mounting bracket 3 with the stabilizing sleeve 7. The top of the outer wall on one side of the movable sleeve 6 is connected and fixed to the top end of the support plate 8. A positioning plate 9 is fixedly installed on the inner side of the vertical part of the support plate 8. The positioning plate 9 is connected and fixed to the bottom of the outer wall of the movable sleeve 6. The above-mentioned structural design improves the stability of the support plate 8 and ensures the stability of the stirring rod 14 during work. A second servo motor 10 is fixed to one end of the support plate 8;

[0034] A second servo motor 10, a driving pulley 11 is fixed to the end of the top output shaft of the second servo motor 10, the driving pulley 11 is connected to one end of a transmission belt 12, the other end of the transmission belt 12 is installed on a driven pulley 13, the driven pulley 13 is fixed to the top of a stirring rod 14, the stirring rod 14 is rotatably installed on the back of the other end of the support plate 8 through an outer wall bearing seat, and a blowing pipe 15 is rotatably installed at the center of the stirring rod 14 through a bearing seat.

[0035] In one embodiment, the front view shape of the support plate 8 is "L"-shaped, and the width of the support plate 8 is greater than the width of the positioning plate 9. The above-mentioned structural design provides a stable installation foundation for the second servo motor 10, the driving pulley 11, the transmission belt 12, the driven pulley 13 and the stirring rod 14.

[0036] In one of the preferred embodiments, the diameter of the driving pulley 11 is smaller than the diameter of the driven pulley 13, and the center of the driving pulley 11 and the center of the driven pulley 13 are on the same vertical plane. The above-mentioned structural design enables the driving pulley 11 to drive the driven pulley 13 and the stirring rod 14 to rotate slowly and stably through the transmission belt 12.

[0037] In one embodiment, the bottom diameter of the stirring rod 14 is larger than the top diameter, and the stirring rod 14 forms a rotating mechanism through the outer wall bearing seat and the support plate 8. The above structural design ensures that the stirring rod 14 can rotate stably to rotate and stir the aluminum liquid.

[0038] In one of the preferred embodiments, the blowing pipe 15 and the stirring rod 14 form a rotating mechanism through a bearing seat installed between the outer wall and the inner wall of the stirring rod 14. The top of the blowing pipe 15 is connected and fixed to the back of the movable sleeve 6. The above-mentioned structural design makes the blowing pipe 15 synchronized with the movable sleeve 6 and opposite to the stirring rod 14. It can only perform synchronous vertical displacement under the drive of the movable sleeve 6. The rotation of the stirring rod 14 will not affect the blowing pipe 15 and the external inert gas supply mechanism connected to it.

[0039] The working principle of the utility model is: when using the device, Figure 1 and Figure 2 The left end of the aluminum liquid tank 1 is connected to the discharge port of the melting furnace, and the aluminum liquid in the melting furnace enters the aluminum liquid tank 1 through the guide channel 2, and then the first servo motor 4 is started, and the first servo motor 4 is controlled to drive the vertical threaded rod 5 to rotate forward. The vertical threaded rod 5 uses the threaded connection relationship to drive the movable sleeve 6 to move down steadily along the vertical part of the mounting bracket 3 with the stabilizing sleeve 7, and the movable sleeve 6 moves down synchronously with the support plate 8, the stirring rod 14 and the blowing pipe 15 until the bottom end of the stirring rod 14 extends into the aluminum liquid in the aluminum liquid tank 1 to a sufficient depth, and the first servo motor 4 is controlled to stop working to lock the vertical threaded rod 5, and the vertical threaded rod 5 uses the thread self-locking to fix the position of the movable sleeve 6;

[0040] Then, the second servo motor 10 is started. The second servo motor 10 drives the driving pulley 11 to rotate stably through the output shaft. The driving pulley 11 drives the driven pulley 13 and the stirring rod 14 to rotate slowly and stably through the transmission belt 12 to stir the aluminum liquid. At the same time, the inert gas is introduced into the aluminum liquid through the inert gas supply mechanism connected to the blowing pipe 15. The top of the blowing pipe 15 is connected to the outer wall of the movable sleeve 6, and the blowing pipe 15 is connected to the inner wall of the stirring rod 14 through the outer wall bearing seat, and will not be affected by the stirring rod 14.

[0041] After the stirring is completed, the air supply to the blowing pipe 15 is stopped, the second servo motor 10 is controlled to stop working, and the first servo motor 4 is controlled to drive the vertical threaded rod 5 to rotate in the opposite direction. The vertical threaded rod 5 uses the threaded connection relationship to drive the movable sleeve 6 to move up with the stirring rod 14 and separate from the aluminum liquid.

[0042] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
