A runner control system for an aluminum alloy container foil

Abstract

This invention discloses a flow channel control system for aluminum alloy container foil, including a flow channel body with a flow channel cavity inside. The flow channel body is equipped with a stroke control component and a fluid stroke guiding component. The fluid stroke guiding component is used to control the flow channel. When the flow rate of molten aluminum alloy is uneven and fluctuates, the guiding angle drive control can be used to adjust the guiding control plate to a horizontal position. This ensures that the guiding control plate and the flow baffle plate maintain a low downward impact potential energy during the flow of molten aluminum alloy. At the same time, in the case of a sudden increase in flow rate, some molten aluminum alloy that has not passed the horizontal guiding control plate can still be guided by the downward impact guiding surface to extend the mixing distance and prolong the melting time of the molten aluminum alloy. This maintains the mixing effect of the refining agent and the molten aluminum alloy after passing through, thereby improving the adaptability to uneven flow rate of molten aluminum alloy.

Description

Technical Field

[0001] This invention relates to the field of container foil processing technology, and in particular to a flow channel control system for aluminum alloy container foil. Background Technology

[0002] In conventional aluminum alloy container processing, when the flow rate of molten aluminum alloy in the flow channel is large, improper temperature control or excessively rapid addition of refining agents can lead to insufficient melting time during the flow of the mixture. This can cause some aluminum composite alloys to deposit at the inlet point, resulting in a decrease in product quality. Therefore, for this wide-width casting and rolling application scenario, conventional flow channels use flow-blocking blocks in the channel wall to increase the inlet slope and provide downward momentum to reduce aluminum composite alloy deposition. However, when the flow rate of molten aluminum alloy is uneven, with fluctuations in flow rate, smaller flows may be blocked by the flow-blocks, preventing them from passing over the blocks. This causes some aluminum composite alloys to deposit directly on the inlet side of the flow channel and remain between the flow-block and the inlet side, affecting normal flow. Therefore, this type of flow channel cannot adapt to adjustments caused by fluctuating flow rates and its adaptability is not ideal. Therefore, we propose a flow channel control system for aluminum alloy container foil. Summary of the Invention

[0003] The main objective of this invention is to provide a flow channel control system for aluminum alloy container foil.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A flow channel control system for aluminum alloy container foil includes a flow channel body with a flow channel cavity formed on its inner side. The flow channel body is equipped with a stroke control component and a fluid stroke guiding component. The fluid stroke guiding component is used for controlling the flow channel. The stroke control component includes a path control drive unit and a side fixing support plate. The path control drive unit is fixedly connected to the top side of the flow channel body. The side fixing support plate is installed between the fluid stroke guiding component and the sliding end of the path control drive unit for initial flow port guidance of the fluid stroke guiding component. With the change of position, the fluid flow guiding assembly includes a flow frame, a guiding control plate, and a fixed-position guide plate. The flow frame slides inside the main body of the flow channel. The guiding control plate and the fixed-position guide plate are symmetrically installed inside the flow frame. The guiding control plate is rotatably connected to the flow frame, and the fixed-position guide plate is fixedly connected to the flow frame. A flow-blocking plate is fixedly connected to the bottom end of the guiding control plate. By adjusting the orientation angle of the guiding control plate, part of the aluminum alloy solution is diverted and discharged through the guiding control plate and the fixed-position guide plate.

[0006] A further improvement of the present invention is that the guiding control plate is provided with a fluid flow obstruction section and a flow conduction section. After the angle of the guiding control plate is adjusted, part of the aluminum alloy solution is guided to the fixed position guide plate through the fluid flow obstruction section and the flow conduction section, thereby diverting and guiding the aluminum alloy solution.

[0007] A further improvement of the present invention is that the fixed-position guide plate has a downward-pointing guide section to extend the flow path of the aluminum alloy solution after passing through the guide control plate.

[0008] A further improvement of the present invention is that a flow guiding column is provided on the inner side of the main body of the flow channel. The flow guiding column penetrates the flow frame and is fixedly connected to the inner wall of the main body of the flow channel for the diversion of aluminum alloy solution.

[0009] A further improvement of the present invention is that a damping flow cavity is formed between the flow frame and the guiding control plate, the flow frame is equipped with a guiding angle drive control, and the transmission end of the guiding angle drive control is fixedly connected to the flow frame, so as to control the flow orifice diameter of the damping flow cavity after the angle of the guiding control plate is adjusted.

[0010] A further improvement of the present invention is that the use steps of a flow channel control system for aluminum alloy container foil include the following steps:

[0011] Step S1: When the aluminum alloy solution is mixed and guided through the main body of the flow channel, the mixed liquid is divided by the flow diversion column and flows in two flow paths towards the direction control plate. Finally, after passing through the position of the obstruction flow cavity, it forms a submerged flow along the flow channel cavity to complete the passage.

[0012] Step S2: When the large-flow aluminum alloy solution flows through the obstruction flow cavity, the guide angle drive control rotates the control plate, causing the flow-blocking plate to shift in the direction of the flow-directing column, thus reducing the flow orifice of the obstruction flow cavity. This allows the aluminum alloy solution to be guided by the fluid obstruction section to the flow conduction surface 323 during flow, providing downward potential energy. After the aluminum alloy solution reaches the control plate 32, the flow rate decreases, and the aluminum alloy solution and the refining agent are initially melted and mixed. The mixing time increases until the aluminum alloy solution has passed the control plate. Then, the downward guiding section maintains a normal flow rate to the outlet end.

[0013] Compared with existing technologies, this invention avoids deposition caused by excessive flow of molten aluminum alloy. It uses a guide angle control to adjust the flow aperture of the flow-blocking cavity via a control plate. This allows the molten aluminum alloy to enter through the inlet side of the flow channel, providing downward pressure. Upon reaching the control plate, the flow rate of the molten aluminum alloy decreases, increasing the mixing time after the initial melting of the molten aluminum alloy and the refining agent. Finally, the molten aluminum alloy is guided through the flow-blocking section to the flow-conducting surface, flowing downwards to the outlet. This reduces deposition in aluminum composite alloys, making it suitable for high-throughput anti-deposition conveying and ensuring molding quality.

[0014] Compared with the prior art, when the flow rate of molten aluminum alloy is uneven and fluctuates, the present invention can adjust the guiding control plate to a horizontal position via the guiding angle drive control. This ensures that the guiding control plate and the flow-blocking plate maintain a low downward impact potential energy during the flow of molten aluminum alloy. Thus, when the flow rate of molten aluminum alloy decreases, it is subjected to a low downward impact potential energy and flows directly through the obstruction flow cavity. This avoids the obstruction of the obstruction flow cavity by the flow-blocking plate and the guiding control plate, preventing the molten aluminum alloy with a reduced flow rate from not being able to pass through the obstruction block. At the same time, in the case of a sudden increase in flow rate, the molten aluminum alloy that has not passed the horizontal guiding control plate can still be guided by the downward impact guide surface to extend the mixing distance and extend the melting time of the molten aluminum alloy. This maintains the mixing effect of the refining agent and the molten aluminum alloy after passing through, thereby improving the adaptability to uneven flow rate of molten aluminum alloy.

[0020] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1. Please refer to Example 1. Figures 1-4 A flow channel control system for aluminum alloy container foil includes a flow channel body 1, with a flow channel cavity 11 formed inside the flow channel body 1. The flow channel body 1 is provided with a stroke control component 2 and a fluid stroke guiding component 3. The fluid stroke guiding component 3 is used for controlling the flow channel. The stroke control component 2 includes a path control drive unit 21 and a side fixing support plate 22. The path control drive unit 21 is fixedly connected to the top side of the flow channel body 1. The side fixing support plate 22 is installed between the fluid stroke guiding component 3 and the sliding end of the path control drive unit 21, and is used to adjust the initial position of the flow port of the fluid stroke guiding component 3. The fluid flow guiding component 3 includes a flow frame 31, a guiding control plate 32, and a fixed guide plate 33. The flow frame 31 slides inside the main body 1 of the flow channel. The guiding control plate 32 and the fixed guide plate 33 are symmetrically installed inside the flow frame 31. The guiding control plate 32 is rotatably connected to the flow frame 31, and the fixed guide plate 33 is fixedly connected to the flow frame 31. A flow-blocking plate 34 is fixedly connected to the bottom end of the guiding control plate 32. By adjusting the orientation angle of the guiding control plate 32, part of the aluminum alloy solution is diverted and discharged through the guiding control plate 32 and the fixed guide plate 33.

[0022] In this embodiment, the present invention is applicable when the flow rate of molten aluminum alloy is uneven, resulting in fluctuations in flow size. The flow method can be adjusted to adapt to this situation. Specifically, the adjustment method involves first controlling the guide angle drive control 35 to drive the guide control plate 32 to a horizontal position. When the molten aluminum alloy enters, the flow-blocking plate 34, positioned horizontally, blocks the flow through the flow-impeding cavity 321, providing a buffer. This ensures that the guide control plate 32 and the flow-blocking plate 34 maintain a low downward pressure potential energy during the flow of the molten aluminum alloy. When the molten aluminum alloy is in a low-flow stage due to uneven fluctuations, the low downward pressure potential energy generated by the flow-blocking plate 34 prolongs the flow at the inlet. During the melting and mixing time, after being blocked, the aluminum alloy solution flows directly to the outlet end of the main body 1 of the guide tank through the obstruction passage 321. This avoids the aluminum alloy solution with reduced throughput not being able to pass the obstruction block, causing direct accumulation at the inlet. When the throughput of aluminum alloy liquid suddenly increases, the portion of aluminum alloy liquid blocked by the flow-blocking plate 34 that has not passed the horizontal state and is directed to the control plate 32 can still be guided by the downward guide section 331 to extend the mixing distance, thereby achieving diversion when the throughput is large. This disperses the flow to extend the melting time of aluminum alloy liquid, maintains the mixing effect of the finer agent and aluminum alloy solution after passing through, improves the adaptability to uneven throughput of aluminum alloy liquid, and thus maintains the quality requirements of the next process in the manufacturing of aluminum alloy container foil.

[0023] The guiding control plate 32 is provided with a fluid flow obstruction section 322 and a flow conduction surface 323. After the angle of the guiding control plate 32 is adjusted, part of the aluminum alloy solution is guided to the fixed-position guide plate 33 through the fluid flow obstruction section 322 and the flow conduction surface 323 to divert and guide the aluminum alloy solution. The fixed-position guide plate 33 is provided with a downward guiding section 331 to extend the flow path of the aluminum alloy solution after passing through the guiding control plate 32. The guiding control plate 32 is in a horizontal state and is combined with When the flow rate of the liquid gold is large, the fluid flow obstruction section 322 can provide a flow guide for the liquid aluminum alloy that has not passed through the guide plate 32 after being blocked by the flow isolation plate 34. This allows some of the liquid aluminum alloy to be diverted through the flow conduction surface 323 and discharged through the downward guide section 331. This diversion of the large flow rate of the liquid aluminum alloy results in a small stream flowing in the flow channel cavity 11, thereby increasing the melting and mixing efficiency and preventing the liquid aluminum alloy from depositing at the feeding end due to insufficient melting caused by excessive flow rate.

[0024] The main body 1 of the flow channel is provided with a flow guiding column 4. The flow guiding column 4 passes through the flow frame 31 and is fixedly connected to the inner wall of the main body 1 of the flow channel to allow the aluminum alloy solution to flow through. The flow guiding column 4 can isolate the aluminum alloy solution initially added into the main body 1 of the flow channel into two streams that flow inside the main body 1 of the flow channel, avoiding the increase in flow rate caused by excessive flow at one time, so that the small stream of aluminum alloy solution can be fully melted and mixed when flowing.

[0025] In this embodiment, a flow-impeding flow cavity 321 is formed between the flow-through frame 31 and the guiding control plate 32. The flow-through frame 31 is equipped with a guiding angle drive control 35, and the transmission end of the guiding angle drive control 35 is fixedly connected to the flow-through frame 31. This drive control 35 is used to control the flow orifice diameter of the flow-impeding flow cavity 321 after the guiding control plate 32 is adjusted. In this embodiment, the guiding angle drive control 35 is a drive motor. After being embedded and assembled inside the flow-through frame 31, its output end is fixedly connected to the guiding control plate 32. This motor is used to rotate the guiding control plate 32 to adjust the tilt angle. This causes the guiding control plate 32 to flip in the direction of the flow-directing column 4 and change the flow orifice diameter of the flow-impeding flow cavity 321 by adapting with the flow-blocking plate 34. This allows for switching of the guiding mode according to the current amount of aluminum alloy liquid added, increasing the adaptability to different amounts of liquid added and ensuring sufficient melting when the flow rate changes.

[0026] Example 2. In this example, the similarities to Example 1 will not be repeated. The difference lies in that, when applying to aluminum alloy liquid requiring stability and high throughput, to prevent excessive flow and sedimentation, the guide angle drive control 35 drives the control plate 32 downwards, causing the flow-blocking plate 34 to engage with the outside of the guide column 4. This changes the flow aperture of the impeding flow cavity 321, allowing the aluminum alloy liquid, after being added through the inlet side of the flow channel, to be simultaneously controlled by the control plate 32, the flow-blocking plate 34, and the flow frame 31 for the current high flow rate. The molten aluminum alloy provides downward potential energy, causing the flow rate to decrease after reaching the guide plate 32. This allows the molten aluminum alloy and the refining agent to initially melt and enter the mixture. After the mixing time increases, the molten aluminum alloy is finally guided to the flow conduction surface 323 by the fluid obstruction section 322 set by the fixed guide plate 33, and then flows downward to the outlet. This allows the molten aluminum alloy to fully melt during flow, effectively reducing the deposition of aluminum composite alloys. This makes it suitable for high-throughput conveying, prevents deposition at the addition point, ensures molding quality, and is suitable for applications in various environments.
