Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, in particular to a vacuum ladle structure. Background Art

[0002] In a step of electrolytic aluminum, molten aluminum is transported to one end of a smelting furnace through a vacuum ladle, and the molten aluminum needs to be pumped out of the vacuum ladle into the smelting furnace for smelting.

[0003] Generally, an ejector is used to pump molten aluminum. One end of the ejector is connected to a molten aluminum suction pipe inside the vacuum ladle, and the other end is connected to the smelting furnace. Compressed air is introduced into the air inlet of the ejector, and the flow of the compressed air causes negative pressure inside the vacuum ladle, pumping the molten aluminum out of the vacuum ladle and into the smelting furnace.

[0004] The prior art is to weld an ejector on the upper end of the vacuum ladle to pump out the molten aluminum inside the vacuum ladle. Since the volume of the vacuum ladle is large, every time molten aluminum is pumped, workers have to climb to the upper end of the vacuum ladle to connect the compressed air pipeline, and the connection process is relatively difficult. After the ejector is used for a long time, it needs to be replaced or repaired. Workers need to remove the ejector from the vacuum ladle. Since it is welded, the removal process is relatively difficult, and after replacement, it needs to be welded again, which is time-consuming and laborious. Summary of the Utility Model

[0005] Aiming at the technical problems existing in the background art, the purpose of the utility model is to provide a vacuum ladle structure, which is convenient for workers to connect pipelines and ejectors, and is also convenient for subsequent installation and replacement of the ejector.

[0030] Embodiment

[0031] As Figures 1-9As shown in the figure, a vacuum ladle structure includes a vacuum ladle 1, a connection assembly, and an ejector 2. The ejector 2 includes a main part 21 and a support part 25 arranged on the main part 21. The support part 25 is connected within the connection assembly. A compressed air pipe 24, an aluminum suction pipe 22, and an aluminum discharge pipe 23 are arranged on the main part 21. The compressed air pipe 24 and the aluminum discharge pipe 23 are respectively connected to two mutually perpendicular surfaces on the main part 21. The connection assembly is arranged in the middle of the vacuum ladle 1, and the ejector 2 is connected to the vacuum ladle 1 through the connection assembly. The connection assembly includes a support plate 3 and a limit plate structure. There are at least two support plates 3. An opening is provided on the circumferential surface of the vacuum ladle 1. The support plates 3 surround the opening and are arranged on the circumferential surface of the vacuum ladle 1. The support part 25 is arranged between adjacent support plates 3. A connection hole 101 is provided at the upper end of the vacuum ladle 1. The aluminum suction pipe 22 is arranged within the connection hole 101. One end of the aluminum suction pipe 22 is connected to the main part 21. Compressed air is introduced into the main part 21 at the compressed air pipe 24, and the compressed air is continuously introduced into the aluminum discharge pipe 23, causing a negative pressure to be generated in the aluminum suction pipe 22, resulting in a negative pressure being formed within the vacuum ladle 1 connected to the aluminum suction pipe 22, enabling the molten aluminum in the vacuum ladle 1 to be drawn out from the aluminum suction pipe 22. At the same time, the aluminum discharge pipe 23 extends into the melting furnace, and the molten aluminum is directly drawn into the melting furnace. The aluminum suction pipe 22 can be continuously connected to the vacuum ladle 1. The ejector 2 is arranged in the middle of the vacuum ladle 1. Workers can directly connect the compressed air pipeline to the ejector 2 without having to climb to the top of the vacuum ladle 1, which not only facilitates the connection of the pipeline and the ejector 2 but also reduces the risk of safety accidents.

[0032] As Figure 1 , 2 , 4, 5, 6, 7, 8, 9 shown, the limit plate structure includes a limit plate 6 and a connection plate 5. The limit plate 6 and the connection plate 5 are arranged in parallel, and an adjustment hole 62 is provided on the limit plate 6, and a threaded hole 51 is provided on the connection plate 5. The adjustment hole 62 and the threaded hole 51 are aligned, and a bolt 7 is arranged within the adjustment hole 62 and the threaded hole 51. The bolt 7 connects the limit plate 6 and the connection plate 5 together. A rotation hole 63 is provided within the adjustment hole 62. The diameter of the rotation hole 63 is larger than the diameter of the adjustment hole 62. One end of the bolt 7 is provided with a limit ring 71. The bolt 7 extends into the adjustment hole 62, and the bolt 7 rotates within the limit plate 6. The limit ring 71 is rotatably arranged within the rotation hole 63. When the bolt 7 is rotated, the position of the bolt 7 is adjusted within the connection plate 5. The lower end of the bolt 7 is rotatably connected to the limit plate 6, and the bolt 7 drives the limit plate 6 to continuously move away from or close to the connection plate 5.

[0033] As Figures 2-9As shown in the figure, a chute 4 is provided on the vacuum ladle 1. The chute 4 does not penetrate the inside of the vacuum ladle 1. The chute 4 is arranged between adjacent support plates 3. One end of the limiting plate 6 is provided with a sliding rod 61. The sliding rod 61 is slidably arranged in the chute 4. The limiting plate structure slides between adjacent support plates 3. The cross-section of the chute 4 is in the shape of a cross. The shape of the sliding rod 61 is the same as that of the chute 4. The limiting plate structure moves in the chute 4 through the sliding rod 61. The shape of the chute 4 is set to prevent the sliding rod 61 from detaching from the outside of the chute 4. This not only strengthens the connection strength between the limiting plate 6 assembly and the vacuum ladle 1, but also facilitates the sliding of the limiting plate 6 assembly in the chute 4. The support part 25 is connected between the support plate 3 and the limiting plate 6. The limiting plate 6 can adjustably clamp the support part 25 to prevent the ejector 2 from detaching from the vacuum ladle 1, and at the same time facilitate subsequent disassembly and replacement.

[0034] As Figures 2-9 shown in the figure, a slot Ⅰ 31 is provided on the support plate 3. The slot Ⅰ 31 is arranged along the movement direction of the limiting plate 6. A slot Ⅱ 52 is provided on the connecting plate 5. When the connecting plate 5 and the support plate 3 are in contact, the slot Ⅰ 31 and the slot Ⅱ 52 are aligned. A stud 8 is arranged in the slot Ⅰ 31 and the slot Ⅱ 52. First, the connecting plate 5 and the support plate 3 are abutted, and the stud 8 is screwed into the slot Ⅰ 31 and the slot Ⅱ 52 to fixedly connect the connecting plate 5 and the support plate 3. At this time, the limiting plate 6 is at the position below the connecting plate 5. Then, the support part 25 is inserted between the support plate 3 and the limiting plate 6. The bolt 7 is threadedly connected to the connecting plate 5. The bolt 7 is rotated. The bolt 7 continuously moves towards the ejector 2, driving the limiting plate 6 to move in the same direction. The limiting plate 6 and the support part 25 continuously fit and clamp the ejector 2.
