Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum alloy flat ingot smelting, and in particular to a slag removal device for smelting recycled aluminum alloy flat ingots. Background Technology
[0002] Recycled aluminum alloy flat ingots are aluminum alloy ingots manufactured using waste aluminum resources as the main raw material through production processes such as pretreatment, smelting, refining, and casting.
[0003] During the smelting and processing of recycled aluminum alloy flat ingots, after all the furnace charge has melted, a layer of slag composed of metal oxides and other waste metal inclusions will form on the surface of the melt. If this slag is not removed in time, it will affect the purity and quality of the aluminum liquid, and thus the quality of the flat ingot. When removing slag, a slag remover is usually added during the melting process. Through the chemical and physical action of the slag remover, the slag on the surface of the melt can be gathered and solidified into a viscous slag layer with suitable plasticity. Then, a retrieval tool is used to remove this slag.
[0004] Currently, when adding slag remover to molten aluminum alloy, it is usually sprinkled directly into the melt by hand. Since the slag remover is in powder or granular form, this method results in uneven distribution of the slag remover during actual operation, affecting the thorough mixing of the slag remover with the melt and thus impacting the slag removal effect. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a slag removal device for smelting recycled aluminum alloy flat ingots that can make the slag removal agent spread more evenly, mix the slag removal agent with the melt more fully, and avoid affecting the slag removal effect.
[0006] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a slag removal device for smelting recycled aluminum alloy flat ingots, comprising a furnace frame and an electric heating smelting furnace. The electric heating smelting furnace has rotating shafts fixedly connected to both its left and right ends coaxially. The electric heating smelting furnace is rotatably mounted on the furnace frame via two sets of rotating shafts. A self-locking motor is fixedly mounted on the right side surface of the furnace frame. The output end of the self-locking motor drives the electric heating smelting furnace to rotate by being fixedly connected to the rotating shafts. A hopper-shaped material trough is rotatably arranged around the top of the electric heating smelting furnace. Discharge holes are evenly distributed at the bottom of the hopper-shaped material trough for adding slag removal agent. A driver is provided between the electric heating smelting furnace and the hopper-shaped material trough. The driver includes a fixed plate, which is fixedly connected to the electric heating smelting furnace. On the upper right side of the outer wall of the smelting furnace, a drive motor is fixedly installed at the top of a fixed plate. A gear is fixedly connected to the output end of the drive motor. A gear ring is rotatably fitted on the upper part of the outer wall of the electric smelting furnace, and the gear ring meshes with the gear. A column is fixedly connected to one side of the top of the gear ring, and a support plate is fixedly connected to the top of the column. The right end of the support plate is fixedly connected to the left end of the hopper-shaped material trough. An agitator is provided on the right side of the hopper-shaped material trough. The agitator includes an ear plate, which is fixedly connected to the right end of the hopper-shaped material trough. An agitating shaft is fixedly connected to the bottom end of the ear plate. The agitating shaft extends to the upper middle position inside the electric smelting furnace and is coaxial with the electric smelting furnace. Three sets of agitating blades are fixedly connected in a ring at equal intervals on the lower side of the outer wall of the agitating shaft.
[0007] Preferably, the electric heating melting furnace has an integrally connected discharge nozzle at the middle of the upper side edge.
[0008] Preferably, reinforcing plates are fixedly connected to both the left and right surfaces of the furnace frame.
[0009] Preferably, the bottom ends of the four legs of the furnace frame are all fixedly connected with anti-slip rubber pads.
[0010] Preferably, the gear, gear ring, column, support plate, bucket-shaped trough, ear plate, stirring shaft and stirring blade are all made of high-strength high-temperature resistant alloy.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, recycled aluminum alloy flat ingots are smelted in an electric melting furnace. After melting, the drive motor is started, which makes the gear ring rotate, thereby causing the gear ring to drive the column to rotate around the electric melting furnace. The column, through the support plate, drives the bucket-shaped material trough to rotate around the electric melting furnace. Then, the slag remover is put into the bucket-shaped material trough. During the process of the bucket-shaped material trough rotating around the electric melting furnace, the slag remover is evenly sprinkled onto the surface of the melt through the feeding hole. In addition, during the rotation of the bucket-shaped material trough, the stirring blades also agitate the melt, thereby promoting the mixing of the slag remover and the melt, and causing the slag to solidify into a viscous slag layer with suitable plasticity. The slag is then removed using a scooping tool. Compared with directly sprinkling the slag remover into the melt by hand, adding the slag remover into the melt by using the bucket-shaped material trough that can rotate around the electric melting furnace can make the slag remover more evenly sprinkled and mix more fully with the melt, avoiding affecting the slag removal effect.

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example
[0014] Please see Figures 1-4This utility model discloses a slag removal device for smelting recycled aluminum alloy flat ingots, comprising a furnace frame 1, an electric smelting furnace 2, a fixed plate 6, and ear plates 13. Rotating shafts 3 are coaxially fixedly connected to both ends of the electric smelting furnace 2. The electric smelting furnace 2 is rotatably mounted on the furnace frame 1 via two sets of rotating shafts 3. A self-locking motor 4 is fixedly mounted on the right side surface of the furnace frame 1. The output end of the self-locking motor 4 drives the electric smelting furnace 2 to rotate by being fixedly connected to the rotating shafts 3. A hopper-shaped material trough 12 is rotatably arranged around the top of the electric smelting furnace 2. The bottom of the hopper-shaped material trough 12 has evenly distributed feeding holes for adding slag removal agent. A fixed plate 6 is fixedly connected to the upper part of the right outer wall of the electric melting furnace 2. A drive motor 7 is fixedly installed at the top of the fixed plate 6, and a gear 8 is fixedly connected to the output end of the drive motor 7. A gear ring 9 is rotatably fitted at the upper part of the outer wall of the electric melting furnace 2, and the gear ring 9 meshes with the gear 8. A column 10 is fixedly connected to one side of the top of the gear ring 9, and a support plate 11 is fixedly connected to the top of the column 10. The right end of the support plate 11 is fixedly connected to the left end of the hopper-shaped material trough 12. An ear plate 13 is fixedly connected to the right end of the hopper-shaped material trough 12, and a stirring shaft 14 is fixedly connected to the bottom end of the ear plate 13. The stirring shaft 14 extends to... The stirring shaft 14 is coaxial with the electric heating furnace 2, and three sets of stirring blades 15 are fixedly connected in a ring at equal intervals on the lower side of the outer wall of the stirring shaft 14. In use, the electric heating furnace 2 is used to melt recycled aluminum alloy flat ingots. After melting, the drive motor 7 is started, which causes the gear ring 9 to rotate, thereby causing the gear ring 9 to drive the column 10 to rotate around the electric heating furnace 2. The column 10, through the support plate 11, drives the hopper-shaped material trough 12 to rotate around the electric heating furnace 2. Then, the slag remover is placed into the hopper-shaped material trough 12, which rotates around the electric heating furnace 2. During the rotation of the smelting furnace 2, the slag remover is evenly distributed onto the surface of the melt through the feeding hole. As the hopper-shaped feed trough 12 rotates, the stirring blades 15 also agitate the melt, thereby promoting the mixing of the slag remover and the melt. This causes the slag to solidify into a viscous slag layer with suitable plasticity, which is then removed using a scooping tool. Compared to directly sprinkling the slag remover into the melt by hand, adding the slag remover to the melt using the hopper-shaped feed trough 12, which can rotate around the electric smelting furnace 2, allows for more even distribution of the slag remover and more thorough mixing of the slag remover and the melt, thus avoiding any impact on the slag removal effect.
[0015] The electric heating furnace 2 has an integrated discharge nozzle 5 at the middle of the upper side edge. After the slag removal is completed, when the melt is poured out, the discharge nozzle 5 makes the melt flow out of the electric heating furnace 2 more smoothly, reducing the possibility of melt spillage.
[0016] The furnace frame 1 has reinforcing plates 16 fixedly connected to both sides of its surface; by setting the reinforcing plates 16, the structure on both sides of the furnace frame 1 can be made more robust, and the structural strength of the furnace frame 1 can be enhanced.
[0017] The bottom of each of the four feet of the furnace frame 1 is fixedly connected with anti-slip rubber pads 17; by setting anti-slip rubber pads 17, the furnace frame 1 is less likely to slip on the ground when placed.
[0018] The gear 8, gear ring 9, column 10, support plate 11, bucket-shaped trough 12, ear plate 13, stirring shaft 14 and stirring blade 15 are all made of high-strength high-temperature resistant alloy. By using high-strength high-temperature resistant alloy, they can withstand the harsh mechanical stress and oxidizing environment at high temperatures, and have high creep strength and endurance strength, as well as good resistance to thermal fatigue and mechanical fatigue.
[0019] This utility model discloses a slag removal device for smelting recycled aluminum alloy flat ingots. The working principle is as follows: The electric melting furnace 2 is existing technology and readily available on the market; its working principle will not be elaborated further here. The recycled aluminum alloy flat ingots are melted in the electric melting furnace 2. After melting, the drive motor 7 is started. The drive motor 7, through the meshing of the gear 8, drives the gear ring 9 to rotate, causing the gear ring 9 to drive the column 10 to rotate around the electric melting furnace 2. This, in turn, causes the column 10, through the support plate 11, to drive the hopper-shaped material trough 12 to rotate around the electric melting furnace 2. Then, an appropriate amount of slag removal agent is placed into the hopper-shaped material trough 12. During the rotation of the hopper-shaped material trough 12 around the electric melting furnace 2, the discharge hole covers the radius of the electric melting furnace 2. After the hopper-shaped material trough 12 completes one revolution, the slag removal agent passes through the discharge hole. The slag remover is evenly spread onto the surface of the melt. During the spreading process, workers can use long sticks to stir the slag remover in the bucket-shaped trough 12 to prevent it from clogging the discharge hole. As the bucket-shaped trough 12 rotates, it also drives the stirring shaft 14 to rotate through the ear plate 13. Since the stirring shaft 14 is coaxial with the electric melting furnace 2, it rotates on its own axis. During the rotation of the stirring shaft 14, it drives the stirring blades 15 to stir the melt, thereby promoting the mixing of the spread slag remover with the melt and causing the slag to solidify into a viscous slag layer with suitable plasticity. Then, the slag is removed using a scooping tool. After the slag removal is completed, the self-locking motor 4 is started. The self-locking motor 4 drives the electric melting furnace 2 to rotate through the rotating shaft 3, causing the electric melting furnace 2 to slowly tilt, thereby allowing the melt to flow smoothly out of the electric melting furnace 2 through the discharge nozzle 5.
[0020] The slag removal device for smelting recycled aluminum alloy flat ingots of this utility model has common mechanical installation, connection and setting methods. As long as it can achieve its beneficial effect, it can be implemented. The electric melting furnace 2, self-locking motor 4 and drive motor 7 of the slag removal device for smelting recycled aluminum alloy flat ingots of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
