Description

Technical Field

[0001] This utility model relates to the technical field of aluminum ingot production and conveying equipment, specifically to an aluminum liquid conveying device for aluminum ingot production. Background Technology

[0002] In the aluminum processing industry, aluminum ingots are a crucial raw material, and their production quality and efficiency directly affect the performance and application range of subsequent aluminum products. With technological advancements and increasingly stringent industrial production requirements, every step in the aluminum ingot production process has become particularly important, especially the transportation and handling of molten aluminum, which directly impacts the final quality of the aluminum ingots.

[0003] The shortcomings of existing technology:

[0004] Currently, in the production of aluminum ingots, the transport of molten aluminum is typically accomplished through simple conveying troughs or pumping systems. While this traditional method achieves the transfer of molten aluminum from the melting furnace to the mold, it has significant drawbacks. Specifically, a large number of air bubbles often become mixed into the molten aluminum during the melting process and subsequent transport. Larger bubbles can float to the surface and break up due to buoyancy, but smaller bubbles, due to the viscosity of the molten aluminum, struggle to float and are thus carried into the mold. These residual air bubbles form pores during the solidification process of the aluminum ingot, severely affecting the forming effect and quality of the ingot, leading to a decrease in its mechanical properties, and potentially even causing defects such as cracks.

[0028] Example

[0029] Please see Figure 1-3As shown, this utility model provides a technical solution for an aluminum liquid conveying device for aluminum ingot production: An aluminum liquid conveying device for aluminum ingot production includes a mounting box 1. A feed trough 2 and a discharge pipe 3 are respectively installed at the upper and lower ends of the mounting box 1. The output end of the discharge pipe 3 is connected to the feed inlet of the mold. A centrifugal assembly 4 is installed inside the mounting box 1, and a drive mechanism 5 for driving the centrifugal assembly 4 is installed at the upper end of the mounting box 1. The centrifugal assembly 4 includes a receiving box 401 and a centrifugal box 404. The receiving box 401 is installed through a partition inside the mounting box 1. The lower end of the receiving box 401 is connected to the end of the discharge pipe 3. A support frame 402 is located above the discharge pipe 3 at the lower end of the receiving box 401. A filter screen 403 for filtering air bubbles in the aluminum liquid is embedded below the support frame 402. Centrifuge box 404 is movably mounted on the upper end of support frame 402, located inside receiving box 401. The output port of feed trough 2 is located above centrifuge box 404. Centrifuge box 404 rotates above support frame 402 driven by drive mechanism 5. The cross-section of the upper opening of receiving box 401 is an inwardly spiraling arc, and the inner arc of the upper opening of receiving box 401 is tangent to the box wall of centrifuge box 404. The inwardly spiraling semi-circle cross-section of the upper opening of centrifuge box 404 is used to prevent aluminum liquid from splashing. A discharge trough 4041 for discharging aluminum liquid is provided at the opening of centrifuge box 404.

[0030] When the device is needed, the centrifuge box 404 is first rotated at a set speed by the drive mechanism 5. Before the molten aluminum enters the mold, the output end of the feed trough 2 first introduces the molten aluminum mixed with small air bubbles into the centrifuge box 404. As the centrifuge box 404 rotates at high speed, the surface of the molten aluminum spreads upward along the inner wall of the centrifuge box 404 until it is ejected along the inner wall of the centrifuge box 404 or ejected from the discharge trough 4041. As the molten aluminum rotates and rises along the inner wall of the centrifuge box 404, the molten aluminum becomes thinner overall, so the small air bubbles in the molten aluminum are able to float to the surface and break. After being ejected from the centrifuge box 404, the molten aluminum is received by the upper opening of the receiving box 401. Since the inner arc of the upper opening of the receiving box 401 is tangent to the box wall of the centrifuge box 404, the molten aluminum can be smoothly transferred into the receiving box 401 without generating new air bubbles due to splashing. Subsequently, the molten aluminum slides down the inner wall of the receiving box 401, and after being filtered through the secondary air bubbles of the filter screen 403, it is discharged into the discharge pipe 3, and finally introduced into the mold through the discharge pipe 3.

[0031] The centrifugal assembly 4 effectively removes small air bubbles during the aluminum liquid transportation process. The entire venting process is simple and efficient. The design of the docking angle between the receiving box 401 and the centrifugal box 404 also effectively avoids the secondary generation of air bubbles during the transfer of aluminum liquid. Ultimately, the amount of air bubbles in the aluminum liquid inside the mold is significantly reduced, and the forming effect and quality of aluminum ingots are significantly improved.

[0032] The drive mechanism 5 includes a cover 501 and a drive shaft 504. The cover 501 is mounted on the upper end of the mounting box 1, and a motor 502 is fixedly mounted on the upper end of the cover 501. The output end of the motor 502 is connected to a gearbox 503. The drive shaft 504 connects the gearbox 503 and the centrifuge box 404. A distance sensor 505 for detecting the height of the molten aluminum is mounted on the upper inner wall of the mounting box 1 above the centrifuge box 404. A controller 506 is also mounted on the upper surface of the mounting box 1. The controller 506 is electrically connected to the gearbox 503 and the distance sensor 505 via wires.

[0033] When the centrifuge chamber 404 needs to rotate, the motor 502 is started. The motor 502, after speed regulation via the gearbox 503, drives the centrifuge chamber 404 to rotate via the drive shaft 504. During the rotation of the centrifuge chamber 404, the distance sensor 505 continuously monitors the liquid level of the molten aluminum inside the centrifuge chamber 404. If the liquid level is too high or continues to rise, the controller 506, upon receiving a signal from the distance sensor 505, adjusts the gearbox 503 to increase the rotational speed of the drive shaft 504 and the centrifuge chamber 404, thereby increasing the discharge rate of the molten aluminum. If the liquid level is too low, the rotational speed of the centrifuge chamber 404 is reduced in the same manner, thereby slowing down the discharge rate of the molten aluminum.

[0034] By controlling the rotational speed of the centrifuge box 404 through the drive mechanism 5, the discharge speed of the molten aluminum is adjusted, so that the exhaust speed and efficiency of the device can match the discharge speed of the smelting furnace, thereby improving the adaptability and application flexibility of the device.

[0035] The upper end of the mounting box 1 is also provided with an exhaust port 6. Due to the continuous input of molten aluminum and the effect of high temperature, if the environment inside the mounting box 1 is sealed, the air pressure may be higher than the external air pressure, which will affect the input and discharge of molten aluminum. The exhaust port 6 can significantly improve the working environment inside the mounting box 1.

[0036] A heating layer 7 is attached to the outside of the receiving box 401. As the aluminum liquid loses heat during centrifugal transfer, its viscosity will also increase. The heating layer 7 helps to ensure the fluidity of the aluminum liquid by heating it.

[0037] Working Principle: When the device is needed, motor 502 is started first. Motor 502, after speed adjustment via gearbox 503, drives centrifuge box 404 to rotate via drive shaft 504. The output end of feed tank 2 first introduces molten aluminum mixed with small bubbles into centrifuge box 404. As centrifuge box 404 rotates at high speed, the molten aluminum surface spreads upwards along the inner wall of centrifuge box 404 and is ejected from discharge tank 4041. After being ejected from centrifuge box 404, the molten aluminum is received at the upper opening of receiving box 401. During the upward rotation of the molten aluminum along the inner wall of centrifuge box 404, small bubbles float to the surface and break. Subsequently, the molten aluminum slides down along the inner wall of receiving box 401, is filtered through secondary bubbles by filter screen 403, and is discharged into discharge pipe 3, finally being introduced into the mold through discharge pipe 3. During the rotation of centrifuge box 404, distance sensor 505 continuously monitors the molten aluminum level in centrifuge box 404. If the liquid level is too high or too low, after receiving the signal from the distance sensor 505, the controller 506 adjusts the speed of the transmission shaft 504 and the centrifuge box 404 by adjusting the gearbox 503 to increase or decrease the speed, thereby adjusting the discharge speed of the aluminum liquid.
