Specific implementation mode

[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation mode of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0026] Example 1, referring to Figures 1 to 7 , this technical solution provides a recycled aluminum ingot melting furnace for waste and miscellaneous aluminum, which includes a melting mechanism, a protection mechanism, a feeding mechanism and a slag fishing mechanism. When the staff uses a transport vehicle to add waste and miscellaneous aluminum into the furnace body 10, it can prevent the waste and miscellaneous aluminum with moisture from being damaged to the staff due to high-temperature expansion after contacting with high temperature, and reduce the heat loss when the furnace body 10 is opened. At the same time, it is convenient for the staff to fish out the waste slag in the aluminum liquid.

[0027] Furthermore, the melting mechanism can melt the waste and miscellaneous aluminum. It includes the furnace body 10, the combustion pool 11 and the feed inlet 12 are arranged at the top of the furnace body 10, the intake pipe 13 at the top of the furnace body 10, and the igniter 14 for igniting gas is arranged inside the furnace body 10.

[0028] During use, the staff pour waste aluminum into the combustion pool 11, start the igniter 14, ignite the gas entering the inside of the furnace body 10 through the inlet pipe, and melt the waste materials. After the waste aluminum is melted, it can be uniformly collected through the liquid delivery block at the bottom of the furnace body 10.

[0029] Furthermore, the protection mechanism can prevent the staff from being injured by an explosion caused by the contact between the moisture in the waste aluminum and high temperature when adding waste aluminum into the combustion pool 11. It includes a placement groove 20 on the furnace body 10. Inside the placement groove 20, there is a hydraulic rod 21. On the hydraulic rod 21, there is a lifting part 22 for sealing the feed inlet 12. On the lifting part 22, there is a driving part 23 and a follower part 24. On the follower part 24, there is a switch part 25 for the staff to stir the waste aluminum.

[0030] Even further, the lifting part 22 includes a lifting plate 221 on the hydraulic rod 21. Inside the furnace body 10, there is a first fixed plate 222. The lifting plate 221 is slidably connected to the first fixed plate 222. On the lifting plate 221, there is a first steel chain 223, which is adjacent to the bottom of the lifting plate 221. On the inner wall of the furnace body 10, there is a first base 224.

[0031] During use, the staff can control the lifting of the lifting plate 221 by starting the hydraulic rod 21. The lifting plate 221 moves up and down on the side wall of the first fixed plate 222. When the lifting plate 221 moves up and down, it drives the first steel chain 223 to move together.

[0032] Even further, the driving part 23 includes a plug rod 231 on the lifting plate 221, which is adjacent to the bottom of the lifting plate 221, and one end of the plug rod 231 penetrates through the lifting plate 221. On the plug rod 231, there is a cross bar 232. The number of plug rods 231 is two, and the two plug rods 231 are respectively connected to the two ends of the cross bar 232. At the middle position of the cross bar 232, there is a threaded rod 233. One end of the threaded rod 233 penetrates through the cross bar 232, and the threaded rod 233 is rotatably connected to the lifting plate 221. On the threaded rod 233, there is a turntable 234.

[0033] During use, when the staff drive the turntable 234 to rotate, the turntable 234 can drive the cross bar 31 to move on the side wall of the threaded rod 233. When the cross bar 31 moves, it can drive the plug rod 231 to move together.

[0034] Even further, the follower part 24 includes a second fixed plate 241 on the inner wall of the furnace body 10. The second fixed plate 241 is located between the first fixed plate 222 and the combustion pool 11. On the second fixed plate 241, there is a follower plate 242. The follower plate 242 is slidably connected to the second fixed plate 241. One end of the first steel chain 223 bypasses the first base 224 and is connected to the follower plate 242.

[0035] During use, when the hydraulic rod 21 drives the lifting plate 221 to descend, the lifting plate 221 can drive the follower plate 242 to rise through the first steel chain 223.

[0036] It should be noted that when the lifting plate 221 is at the uppermost position, the follower plate 242 cooperates with the second fixed plate 241 to seal the furnace body 10. At this time, when the staff drives the turntable 234, the insertion rod 231 can be located below the follower plate 242. At this time, when the staff drives the hydraulic rod 21 to drive the lifting plate 221 to rise, the lifting plate 221 drives the insertion rod 231 to rise, and the insertion rod 231 can drive the follower plate 242 to rise together, so that the lifting plate 221 and the follower plate 242 rise simultaneously, which is convenient for the staff to clean up the waste residue subsequently.

[0037] Furthermore, the switch part 25 includes a through port 251 on the follower plate 242, and a turning plate 252 is arranged at the through port 251.

[0038] During use, the staff can directly push open the turning plate 252 with the stirring rod to stir the waste scrap aluminum in the combustion pool 11, making the melting of the waste scrap aluminum more sufficient.

[0039] Further, the feeding mechanism facilitates the staff to feed materials and avoids the staff directly pushing the waste scrap aluminum, keeping the staff away from danger. It includes an inclined chute 30 opened on the furnace body 10, the inclined chute 30 communicates with the combustion pool 11, a horizontal plate 31 is arranged inside the furnace body 10, the horizontal plate 31 is located between the inclined chute 30 and the combustion pool 11, a turning part 32 for temporarily placing waste scrap aluminum is arranged inside the inclined chute 30, a vibrating part 33 is arranged inside the furnace body 10, and a blocking part 34 for preventing the waste residue from falling is arranged on the horizontal plate 31.

[0040] Furthermore, the turning part 32 includes a placing plate 321 inside the inclined chute 30, a second steel chain 322 is connected to the placing plate 321, one end of the second steel chain 322 away from the placing plate 321 is connected to the follower plate 242, the placing plate 321 is rotatably connected to the inner wall of the inclined chute 30 through a hinge, an arc-shaped rod 323 is connected to the bottom of the placing plate 321, one end of the arc-shaped rod 323 away from the placing plate 321 is connected to a vertical rod 324, the vertical rod 324 is located outside the furnace body 10, one end of the vertical rod 324 away from the arc-shaped rod 323 is connected to a second base 325, the second base 325 is installed on the outer side wall of the furnace body 10, and the vertical rod 324 can be turned around the second base 325.

[0041] During use, when the lifting plate 221 is at the uppermost position, the lifting plate 221 drives the second steel chain 322, and the second steel chain 322 drives the placing plate 321 to be horizontal, which is convenient for the staff to place the waste scrap aluminum on the placing plate 321 and facilitates the subsequent entry of the waste scrap aluminum into the combustion pool 11.

[0042] Further, the jitter part 33 includes a groove 331 inside the furnace body 10. The groove 331 communicates with the inclined groove 30. A shrapnel 332 is arranged inside the groove 331. An annular groove 333 is arranged on the side wall of the arc-shaped rod 323. One end of the shrapnel 332 is located inside the annular groove 333. The number of the annular grooves 333 is multiple, and the multiple annular grooves 333 are evenly distributed on the side wall of the arc-shaped rod 323.

[0043] During use, when the arc-shaped rod 323 rotates around the second base 325, the shrapnel 332 can sequentially strike the inner walls of the multiple annular grooves 333, causing the placement plate 321 to vibrate, so that the waste aluminum on the placement plate 321 can better slide into the combustion pool 11.

[0044] Further, the blocking part 34 includes a baffle 341 on the cross plate 31. The baffle 341 is connected to the cross plate 31 through a hinge. The baffle 341 is made of a light heat-resistant material. A hook plate 342 and a third steel chain 343 are arranged on the baffle 341. A third base 344 is arranged on the inner wall of the furnace body 10. One end of the third steel chain 343 bypasses the third base 344 and is connected to the follower plate 242.

[0045] During use, when the follower plate 242 rises a certain distance, the follower plate 242 drives the third steel chain 343. The third steel chain 343 drives the baffle 341 to flip around the cross plate 31, and the baffle 341 drives the hook plate 342 to flip.

[0046] Further, the slag fishing mechanism can fish out the waste slag in the molten aluminum, including a docking plate 40 on the follower part 24. The docking plate 40 is installed on the follower plate 242 and is located at the bottom of the follower plate 242. At the same time, the docking plate 40 is located above the combustion pool 11. A through hole 41 is opened on the docking plate 40, and a slag fishing part 42 is arranged on the inner wall of the through hole 41.

[0047] During use, when the follower plate 242 rises, it can drive the docking plate 40 to rise.

[0048] Further, the slag fishing part 42 includes an inclined plate 421 on the inner wall of the through hole 41. A water drainage hole 422 and a rectangular hole 423 are opened on the inclined plate 421. The water drainage hole 422 is adjacent to the bottom of the inclined plate 421.

[0049] During use, the waste slag after melting the waste aluminum will float on the liquid surface of the molten aluminum. When the docking plate 40 rises, it can drive the inclined plate 421 to rise. When the inclined plate 421 rises, it can drive the waste slag in the molten aluminum to separate from the molten aluminum, and the molten aluminum flows into the combustion pool 11 through the water drainage hole 422 on the inclined plate 421.

[0050] Further, when the follower plate 242 drives the docking plate 40 to contact the hook plate 342, the follower plate 242 pulls the baffle plate 341 through the steel chain.

[0051] Specifically, when the docking plate 40 drives the inclined plate 421 to rise, the inclined plate 421 can drive the hook plate 342 to flip upward when contacting the hook plate 342, and the hook plate 342 drives the baffle plate 341 to flip. When the hook plate 342 drives the baffle plate 341 to contact the bottom of the inclined plate 421, the baffle plate 341 covers the water drain port 422, preventing the waste residue from falling back into the molten aluminum through the water drain port 422 when the staff collects the waste residue.

[0052] It should be noted that when the inclined plate 421 rises to the highest point, the bottom of the inclined plate 421 is level with the top of the hook plate 342, facilitating the movement of the waste residue on the inclined plate 421 to the placing plate 321. At this time, the setting of the third steel chain 343 can prevent the baffle plate 341 from driving the hook plate 342 to descend under the action of gravity.

[0053] Working principle: When the staff first starts smelting scrap aluminum, the staff can use a forklift or a trolley to put the scrap aluminum into the interior of the combustion pool 11 through the turning plate 252, and drive the igniter 14. The igniter 14 ignites the gas to smelt the scrap aluminum. When adding scrap aluminum subsequently, to avoid accidents caused by the high-temperature expansion of moisture and harm to the staff, the staff places the scrap aluminum on the placing plate 321. At this time, the staff drives the forklift away and starts the hydraulic rod 21. The hydraulic rod 21 drives the lifting plate 221 to descend. While the lifting plate 221 descends, it drives the first steel chain 223. The first steel chain 223 drives the follower plate 242 to rise. While the lifting plate 221 descends, the second steel chain 322 loses the pulling force on the placing plate 321, causing the placing plate 321 to turn downward under the action of the heavy object and gravity. When the placing plate 321 inclines downward, the scrap aluminum on the placing plate 321 slides off the placing plate 321, pushes open the baffle 341, and then falls into the interior of the combustion pool 11. During the turning process of the placing plate 321, the placing plate 321 drives the arc rod 323 to turn together. During the turning process of the arc rod 323, it continuously contacts the elastic piece 332. The elastic piece 332 strikes the annular groove 333 in sequence, making the scrap aluminum on the placing plate 321 easier to slide into the interior of the combustion pool 11 from the placing plate 321. During the descending process of the lifting plate 221, the lifting plate 221 can drive the first steel chain 223. The first steel chain 223 drives the follower plate 242 to rise on the side wall of the second fixing plate 241. The follower plate 242 drives the docking plate 40 to rise. When the docking plate 40 rises, it drives the inclined plate 421 to rise. When the inclined plate 421 rises, it can scoop up the waste residue floating on the liquid surface of the aluminum liquid. When the inclined plate 421 rises to contact the hook plate 342, the follower plate 242 drives the third steel chain 343. The third steel chain 343 is used to keep the position of the baffle 341 unchanged. The bottom of the inclined plate 421 drives the hook plate 342 to turn. The hook plate 342 drives the baffle 341 to turn. When the baffle 341 contacts the bottom of the inclined plate 421, the bottom of the lifting plate 221 contacts the bottom surface inside the furnace body 10, preventing the waste residue on the inclined plate 421 from falling from the water drainage port 422. At the same time, the bottom of the inclined plate 421, the top of the hook plate 342, and the top of the cross plate 31 are horizontal. At this time, the staff can drive the turntable 234 to make the cross bar 232 drive the insertion rod 231 to move to the bottom of the follower plate 242. At this time, by controlling the hydraulic rod 21, the lifting plate 221 can be driven to rise. At this time, since the first steel chain 223 loses the pulling force, the follower plate 242 will descend under the action of gravity. When the lifting plate 221 rises, it can drive the insertion rod 231 to rise. The insertion rod 231 can drive the follower plate 242 to rise again, causing the lifting plate 221 and the follower plate 242 to rise to the highest position together. At this time, the lifting plate 221 drives the second steel chain 322. The second steel chain 322 drives the placing plate 321 to rise until it returns to the horizontal state. The staff can use a hook rod to hook out the waste residue on the inclined plate 421. At this time, the staff places the scrap aluminum on the placing plate 321 again,Control the hydraulic rod 21 to drive the lifting plate 221 to descend, so that the waste aluminum on the placing plate 321 continues to enter the interior of the combustion pool 11 through the inclined chute 30. At this time, the follower plate 242 still drives the docking plate 40 to be at the highest position. The staff reversely drives the turntable 234, so that the insertion rod 231 moves away from the bottom of the follower plate 242. Start the hydraulic rod 21 to drive the lifting plate 221 to rise, so that the follower plate 242 can drive the docking plate 40 to descend. The docking plate 40 drives the inclined plate 421 to descend into the molten aluminum. The new waste residue rises to the liquid surface of the molten aluminum. When the subsequent inclined plate 421 rises, it can drive part of the waste residue to separate from the molten aluminum. Repeat this operation to complete the smelting of the molten aluminum.

[0054] Embodiment 2. The difference between this embodiment and the first embodiment is that: this technical solution provides a processing technology for waste aluminum, including first sorting, drying and cutting the waste aluminum, and cutting the large waste aluminum into appropriate sizes; then putting the processed waste aluminum into the furnace body 10, heating it to above 660 °C to melt the waste aluminum, and stirring during this period to promote melting and uniform composition; adding a refining agent to the molten aluminum after smelting, performing degassing and impurity removal treatment, making the refining agent fully act through stirring, and then standing still to precipitate impurities; using a slag remover to react with oxides and salts in the molten aluminum to generate dross, and removing the dross through slag removal equipment to improve the purity of the molten aluminum; collecting the molten aluminum and pouring it into a preheated mold, controlling the pouring temperature and speed to ensure that the molten aluminum uniformly fills the mold to form qualified aluminum ingots.
