Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy preparation technology, specifically to a slag removal device for aluminum liquid refining. Background Technology

[0002] Utility model application CN202411498900.3 discloses an aluminum molten residue treatment device for aluminum alloy preparation. The device uses a stirring and slag removal mechanism to simultaneously scoop and scrape away the residue after the reaction. However, during scooping, the molten aluminum rises with the residue, resulting in slow scooping speed and low work efficiency. Furthermore, the molten aluminum remains on the stirring and slag removal mechanism after cooling, easily leading to aluminum waste. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a slag removal device for aluminum liquid refining.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A slag removal device for aluminum molten refining, comprising:

[0006] Smelting furnace;

[0007] A base, on which a tilting component is provided, the tilting component being able to tilt the smelting furnace;

[0008] A guide bracket, on which a linear slide is mounted, and a lifting top plate is mounted on the slider of the linear slide;

[0009] A slag removal assembly is mounted on a lifting top plate so that the slag removal assembly moves up and down with the lifting top plate. The slag removal assembly is used to clean the floating slag on the surface of the molten aluminum.

[0010] The linear slide table drives the lifting top plate to descend the slag removal component. The slag removal component cleans the floating slag on the surface of the molten aluminum. The slag is collected and cleaned by rotation, which facilitates the removal of slag and avoids the slag affecting the refining of molten aluminum, thus improving the quality of the finished product. The tilting component tilts the smelting furnace, making it easier to pour out the molten aluminum.

[0011] Furthermore, the slag removal assembly includes a motor bracket, which is installed on one side of the top of the lifting top plate. A rotary motor is installed on the motor bracket in a vertical position. The output end of the rotary motor is connected to a drive shaft, which passes through the lifting top plate. A fixing member is connected to the bottom end of the drive shaft. An inclined scraper is connected to one side of the fixing member, and a filter screen plate is installed inside the fixing member.

[0012] The fixing component and the inclined scraper rotate, and the scum on the surface of the molten aluminum flows along the inclined scraper to the filter screen plate. The filter screen plate is lower than the top surface of the fixing component, so the scum will not flow out of the filter screen plate. The molten aluminum on the filter screen plate can flow out through the filter holes, leaving the scum on the filter screen plate. This makes it easy to collect and clean the scum, avoids the scum from affecting the refining of the molten aluminum, and improves the quality of the finished product.

[0013] Furthermore, the tilting component includes a mounting frame connected to a base, a rotating shaft rotatably connected to the mounting frame, one end of the rotating shaft being fixedly connected to a smelting furnace, a drive motor mounted on the mounting frame, and the output end of the drive motor being connected to one end of the rotating shaft.

[0014] Furthermore, the inclined scraper has a cavity inside, the fixing member is hollow inside, and heating tubes are installed in the cavity and the fixing member. An electric slip ring is connected to the drive shaft. The electric slip ring is located above the lifting top plate. Two guide plates are connected to the surface of the inclined scraper, and one of the guide plates is in contact with the inner wall of the melting furnace.

[0015] The heating element heats the inclined scraper and the fixing component, and the heat can be transferred to the filter screen plate. When collecting slag, the aluminum liquid can be heated to prevent the aluminum liquid from remaining on the inclined scraper, fixing component and filter screen plate after cooling, thus avoiding waste of aluminum liquid.

[0016] Furthermore, a guide slide bar is installed on the guide bracket, and the lifting top plate slides up and down along the guide slide bar.

[0017] Furthermore, the drive shaft is a hollow rotating shaft, and the connecting wire of the electric slip ring passes through the inside of the drive shaft and connects to the heating tube. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] This utility model provides, for example Figure 1-5 The following are included:

[0027] Smelting furnace 1;

[0028] Base 2, with tilting component 3 on base 2, which can tilt smelting furnace 1;

[0029] Guide bracket 4, a linear slide 5 is installed on the guide bracket 4, and a lifting top plate 6 is installed on the slider of the linear slide 5;

[0030] The slag removal component 7 is mounted on the lifting top plate 6 so that the slag removal component 7 moves up and down with the lifting top plate 6. The slag removal component 7 is used to clean the floating slag on the surface of the molten aluminum.

[0031] Aluminum ingots or scrap aluminum are placed into smelting furnace 1 and melted into molten aluminum. Smelting furnace 1 is existing technology and will not be described in detail. During the smelting process, slag will float on the surface of the molten aluminum. The linear slide 5 starts to work. The slider of the linear slide 5 drives the lifting top plate 6 to descend. The lifting top plate 6 drives the slag cleaning component 7 to descend. The slag cleaning component 7 cleans the slag floating on the surface of the molten aluminum in the molten aluminum. The slag is collected and cleaned by rotation, which facilitates the removal of slag and avoids the slag affecting the refining of molten aluminum, thus improving the quality of the finished product. The tilting component 3 tilts smelting furnace 1 to facilitate the pouring out of molten aluminum in smelting furnace 1.

[0032] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 4 The slag removal assembly 7 includes a motor bracket 8, which is installed on one side of the top of the lifting top plate 6. A rotary motor 9 is installed on the motor bracket 8. The rotary motor 9 is installed in a vertical position. The output end of the rotary motor 9 is connected to a drive shaft 10. The drive shaft 10 passes through the lifting top plate 6. A fixing member 11 is connected to the bottom end of the drive shaft 10. An inclined scraper 12 is connected to one side of the fixing member 11. A filter screen plate 13 is installed inside the fixing member 11.

[0033] The linear slide 5 drives the lifting top plate 6 to descend, causing the inclined scraper 12 to descend into the molten aluminum. The rotary motor 9 starts working, and the output end of the rotary motor 9 drives the drive shaft 10 to rotate. The drive shaft 10 drives the fixed part 11 and the inclined scraper 12 to rotate. The scum on the surface of the molten aluminum flows along the inclined scraper 12 onto the filter screen plate 13. The filter screen plate 13 is lower than the top surface of the fixed part 11, so the scum will not flow out of the filter screen plate 13. The molten aluminum on the filter screen plate 13 can flow out through the filter holes, leaving the scum on the filter screen plate 13. This makes it easy to collect and clean the scum, avoids the scum from affecting the refining of the molten aluminum, and improves the quality of the finished product.

[0034] Refer to the instruction manual appendix Figure 3 The tilting component 3 includes a mounting frame 14, which is connected to the base 2. A rotating shaft 15 is rotatably connected to the mounting frame 14. One end of the rotating shaft 15 is fixedly connected to the smelting furnace 1. A drive motor 16 is mounted on the mounting frame 14, and the output end of the drive motor 16 is connected to one end of the rotating shaft 15.

[0035] When it is necessary to pour out the molten aluminum, the drive motor 16 starts to work. The output end of the drive motor 16 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the smelting furnace 1 to rotate and tilt it, so as to facilitate the pouring out of the molten aluminum in the smelting furnace 1.

[0036] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 5The inclined scraper 12 has a cavity 17 inside, and the fixing member 11 is hollow inside. Heating tubes 18 are installed in the cavity 17 and the fixing member 11. An electric slip ring 19 is connected to the drive shaft 10. The electric slip ring 19 is located above the lifting top plate 6. Two guide plates 20 are connected to the surface of the inclined scraper 12. One guide plate 20 is in contact with the inner wall of the melting furnace 1.

[0037] The heating tube 18 starts working, heating the inclined scraper 12 and the fixing member 11. The heat can be transferred to the filter screen plate 13. When collecting slag, the aluminum liquid can be heated to prevent the aluminum liquid from remaining on the inclined scraper 12, fixing member 11 and filter screen plate 13 after cooling. When rotating, the two guide plates 20 can guide the aluminum liquid, so that the aluminum liquid on the surface flows to the inclined scraper 12, which improves the slag removal effect. After the slag removal component 7 rises, the heating tube 18 will continue to heat for a period of time, so that the aluminum liquid on the inclined scraper 12 and filter screen plate 13 flows back into the smelting furnace 1, preventing the aluminum liquid from remaining on the inclined scraper 12 and filter screen plate 13 after cooling and avoiding waste of aluminum liquid.

[0038] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The guide bracket 4 is equipped with a guide slide rod 21, and the lifting top plate 6 slides up and down along the guide slide rod 21.

[0039] The lifting top plate 6 slides along the guide slide rod 21 during lifting and lowering. The guide slide rod 21 guides the lifting top plate 6 and prevents the threaded parts on the lifting top plate 6 and the linear slide table 5 from being completely deformed.

[0040] Refer to the instruction manual appendix Figure 2 The drive shaft 10 is a hollow rotating shaft, and the connecting wire of the electric slip ring 19 passes through the inside of the drive shaft 10 and connects to the heating tube 18.

[0041] The heating element 18 is powered by an electric slip ring 19, and the connecting wire of the electric slip ring 19 passes through the inside of the drive shaft 10 to avoid damage to the connecting wire.
