Description

Technical Field

[0001] This utility model relates to an aluminum overflow device for a refined aluminum tank, belonging to the field of refined aluminum production technology. Background Technology

[0002] With the increase in aluminum purity, its corrosion resistance, plasticity, conductivity, and reflectivity are all greatly improved. Furthermore, the excellent properties of high-purity refined aluminum have led to its increasingly wide range of applications. In recent years, with the steady growth of China's economy, the demand for refined aluminum with higher purity than primary aluminum has grown rapidly in many fields of modern industry, such as electronics, electrolytic capacitors, integrated circuit wiring materials, computer memory disks, superconductors, magnetic levitation suspension materials, spraying materials, low-temperature electromagnetic components, solar energy utilization, aerospace, automotive, and military industries. Therefore, developing refined aluminum baths and related technologies suitable for China's national conditions is of great significance.

[0003] Currently, the three-layer liquid aluminum electrolytic refining technology is a widely used industrial production technology for purifying aluminum (AL≥99.998%) both domestically and internationally. The traditional methods for removing aluminum from the aluminum tank are mainly: vacuum mechanical aluminum removal and manual aluminum removal by scooping with a spoon.

[0004] Traditional aluminum tapping method

[0005] Figure 2 This refers to the vacuum mechanical aluminum extraction method. This method requires a large investment and consumes a lot of compressed air energy. In particular, the siphon pressure of vacuum aluminum extraction is relatively high, which can easily cause turbulence and interface fluctuations in the refined aluminum liquid in the refined aluminum tank during the aluminum extraction process. This leads to increased production instability, resulting in losses from the secondary oxidation reaction of refined aluminum and reduced current efficiency.

[0006] Figure 3 The method of manually scooping out aluminum with a spoon has drawbacks such as high labor intensity, harsh working environment, and low work efficiency.

[0007] The two traditional aluminum tapping methods mentioned above are not conducive to the flexible layout of aluminum tapping tank production and have shortcomings such as unreasonable investment, low work efficiency and harsh working environment. They are no longer suitable for the needs of my country's new industrialization process. Summary of the Invention

[0008] The purpose of this invention is to provide a device for overflowing aluminum from a refined aluminum tank. This device has the advantages of relatively simple structure, high efficiency, low investment, and low energy consumption.

[0009] The technical solution of this utility model is as follows: A device for overflowing aluminum from a refined aluminum tank includes a refined aluminum tank, an overflow chute is provided at the top of the refined aluminum tank, a refined aluminum lifting bag is provided below the outlet of the overflow chute, the refined aluminum lifting bag is placed on a lifting bag transport vehicle, and the lifting bag transport vehicle is set on a track.

[0010] In the aforementioned aluminum overflow device for a fine aluminum trough, a throttling valve is provided on the overflow chute.

[0011] In the aforementioned aluminum overflow device for a fine aluminum trough, the track passes through multiple fine aluminum troughs.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has the following advantages:

[0013] 1) The device of this utility model makes full use of the height difference between the operating surface and the ground in the aluminum refinery workshop and the principle of self-overflow of the aluminum liquid as it rises to realize the online overflow of aluminum from the aluminum refinery tank. Its structure is simple and easy to operate (simply move the lifting and transporting vehicle to align with the overflow chute).

[0014] 2) The device of this utility model can enable multiple aluminum tanks in the aluminum refinement workshop to share a set of lifting and transport vehicles and aluminum lifting bags, and perform aluminum discharge operations in real time as needed, which not only saves investment, but also greatly simplifies the operation process of aluminum discharge from the aluminum refinement tank.

[0015] 3) The device of this utility model can basically realize unmanned operation of the aluminum discharge process in the aluminum tank, which can significantly reduce the labor cost of production.

[0016] 4) The device of this utility model avoids operators from directly contacting high-temperature production equipment, which can greatly improve the operating environment of aluminum production, thus laying a solid foundation for building an environmentally friendly enterprise.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] An embodiment of this utility model: A device for overflowing aluminum from a refined aluminum tank includes a refined aluminum tank 1, an overflow chute 3 is provided at the top of the refined aluminum tank 1, a refined aluminum lifting bag 5 is provided below the outlet of the overflow chute 3, the refined aluminum lifting bag 5 is placed on a lifting bag transport vehicle 6, and the lifting bag transport vehicle 6 is set on a track 7.

[0023] The aluminum slurry 1 of this invention is a continuously producing metallurgical furnace, producing refined aluminum liquid (product) 24 hours a day. The refined aluminum liquid 2 produced by the aluminum slurry 1 is located at the top layer of the slurry. As production continues, the height of the refined aluminum liquid 2 also increases. When the height of the refined aluminum liquid 2 exceeds the overflow port, it flows through the overflow chute 3 to the refined aluminum ladle 5, thus completing the online overflow of aluminum from the aluminum slurry 1. The refined aluminum ladle 5 is transported along the track 7 by the ladle transport vehicle 6. The track 7 ensures that when the ladle transport vehicle 6 stops, the refined aluminum ladle 5 is at a suitable distance from the overflow chute 3, preventing the refined aluminum liquid 2 from falling outside the refined aluminum ladle 5 during overflow.

[0024] The overflow chute 3 is equipped with a throttle valve 4. During the outflow of refined aluminum liquid 2, its size can be adjusted by the throttle valve 4 on the overflow chute 3. When the refined aluminum lifting ladle 5 leaves the overflow chute 3 at its location, the throttle valve 4 on the overflow chute 3 is closed to prevent the refined aluminum liquid 2 from flowing out.

[0025] The track 7 passes through multiple aluminum troughs 1, enabling multiple aluminum troughs 1 in the aluminum workshop to share a set of lifting and transporting vehicles 6 and aluminum lifting bags 5, thus achieving full and rational utilization of resources.
