Description

Technical Field

[0001] This utility model belongs to the field of slag removal technology, specifically relating to a slag removal device for aluminum liquid discharge. Background Technology

[0002] Aluminum molten metal filtration refers to the process of filtering molten aluminum to remove impurities and solid particles, thereby improving the quality and purity of the aluminum alloy. During smelting and casting, molten aluminum is contaminated by various impurities, such as oxides, inclusions, and metallic slag. These impurities adversely affect the properties and processing characteristics of the aluminum alloy, thus requiring filtration to remove them. Floating slag that is not completely removed when the molten aluminum is discharged from the furnace is also discharged along with it. However, this slag is difficult to remove manually, mainly because the furnace is tilted, forcing it to be carried along with the molten aluminum. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slag removal device for aluminum liquid discharge. It has a simple structure and is convenient and practical. The slag is scraped off from the surface of the aluminum liquid by the slag removal bucket, and the slag is easily removed by the hook handle so that the aluminum slag inside can be discharged.

[0004] A slag removal device for molten aluminum discharge includes an aluminum furnace and a slag removal device. The slag removal device is installed at the inlet and outlet of the aluminum furnace. The slag removal device includes a U-shaped guide port, a U-shaped guide nozzle, a first side plate, a connecting rod, and a slag removal hopper. The U-shaped guide port is connected to the inlet and outlet of the aluminum furnace and is connected to the U-shaped guide nozzle. Two first side plates are connected to the sides of the U-shaped guide port away from the aluminum furnace. The connecting rod is connected between the two first side plates. The slag removal hopper is hooked onto the connecting rod.

[0005] Preferably, the slag removal hopper includes a connecting rod, hooks, a second side plate, a bottom plate, a filter plate, and an overflow filter plate. At least one of the hooks is connected to the connecting rod, two second side plates are connected to both ends of the connecting rod, the bottom plate, the filter plate, and the overflow filter plate are connected between the two second side plates, the bottom plate, the filter plate, and the overflow filter plate are arranged in a U-shape, and the filter plate is connected between the bottom plate and the overflow filter plate.

[0009] (1) The present invention provides a slag removal device for aluminum liquid discharge. It has a simple structure and is convenient and practical. The slag is scraped off the surface of the aluminum liquid through the slag removal bucket, and the slag is removed by the hook handle so that the aluminum slag inside can be discharged.

[0010] (2) The aluminum slag removal device of this utility model filters out aluminum slag through a filter plate and an overflow filter plate, while allowing the aluminum liquid to pass smoothly through the slag removal hopper, thus avoiding the aluminum liquid being discharged from the slag removal hopper.

Detailed Implementation

[0012] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0013] like Figures 1 to 3As shown; a slag removal device for molten aluminum discharge includes an aluminum furnace 1 and a slag removal device 2. The slag removal device 2 is installed at the inlet and outlet of the aluminum furnace 1. The slag removal device 2 includes a U-shaped guide port 21, a U-shaped guide nozzle 22, a first side plate 23, a connecting rod 24, and a slag removal hopper 25. The U-shaped guide port 21 is connected to the inlet and outlet of the aluminum furnace 1 and is connected to the U-shaped guide nozzle 22. Two first side plates 23 are connected to the sides of the U-shaped guide port 21 away from the aluminum furnace 1. The connecting rod 24 is connected between the two first side plates 23. The slag removal hopper 25 is hooked on the connecting rod 24. The slag removal hopper 25 includes a connecting rod 26, a hook 27, and a second side plate. 28. A base plate 29, a filter plate 210, and an overflow filter plate 211; at least two hooks 27 are connected to a connecting rod 26; two second side plates 28 are connected to both ends of the connecting rod 26; the base plate 29, filter plate 210, and overflow filter plate 211 are connected between the two second side plates 28; the base plate 29, filter plate 210, and overflow filter plate 211 are arranged in a U-shape; the filter plate 210 is connected between the base plate 29 and the overflow filter plate 211; a hook handle is connected to the connecting rod 26; a number of screw holes 212 for installing positioning bolts are provided on the first side plate 23; the base plate 29 and the filter plate 210 are arranged in a V-shape.

[0014] When the aluminum furnace 1 tilts to discharge molten aluminum, the molten aluminum enters the U-shaped guide nozzle 22 through the U-shaped guide port 21 and is discharged through the U-shaped guide nozzle 22. While the aluminum furnace 1 is tilted, the slag hopper 25 remains vertical because its hook 27 is suspended from the connecting rod 24. As the molten aluminum flows through, the slag is blocked by the overflow filter plate 211, and the filtered molten aluminum passes through the overflow filter plate 211 and enters the space between the overflow filter plate 211 and the bottom plate 29. As the molten aluminum level gradually rises, it submerges the overflow filter plate 211 and the bottom plate 29. After step 9, the slag enters the space between the filter plate 211 and the bottom plate 29, while the molten aluminum is filtered out through the filter plate 210, achieving the purpose of filtering out the floating aluminum slag while the molten aluminum passes through normally. After the molten aluminum is discharged, the slag hopper 25 loses the driving force of the molten aluminum flow and remains vertical due to its weight. The aluminum slag is filtered and retained between the V-shaped plate 29 and the filter plate 210. When cleaning the aluminum slag, the hook on the rod is used to hook the handle to remove the slag hopper 25, and then the aluminum slag can be cleaned.

For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
