[0043] Specifically, relevant personnel start the hydraulic cylinder 231 to drive the movable rod 232 to perform reciprocating lifting motion, and then drive the piston plate 22 to perform reciprocating lifting motion through the movable rod 232, and then achieve the purpose of reciprocatingly feeding the aluminum block onto the fixed grinding ring 24 through the mutual cooperation of the piston plate 22 and the fixed tube 21.

[0044] In one embodiment of the present application, Figure 1-Figure 4As shown, the linkage mechanism 26 may include a sealing cylinder 261 and a driven gear 262 .

[0045] The sealing cylinder 261 is sleeved on the smelting furnace 1 and communicated with the interior of the smelting furnace 1 . The driven gear 262 is sleeved on the dynamic grinding ring 25 and circumferentially slidably connected to the bottom of the inner wall of the sealing cylinder 261 through a sliding key.

[0046] Specifically, the driven gear 262 is connected to the sealing cylinder 261 in a circumferential sliding manner through a sliding key, so as to achieve the purpose of rotating the dynamic grinding ring 25 in the smelting furnace 1.

[0047] In one embodiment of the present application, Figure 1-Figure 4 As shown, the linkage mechanism 26 described in the above embodiment may also include a spur rack 263 , a linkage gear 264 , a rotating rod 265 , a rotating shaft 266 , a vertical bevel gear 267 , a horizontal bevel gear 268 and a driving gear 269 .

[0048] Among them, the rotating rod 265 is rotatably arranged in the smelting furnace 1, the linkage gear 264 is sleeved on the rotating rod 265, the spur rack 263 is fixedly arranged on the movable rod 232, and the spur rack 263 is meshed and connected with the linkage gear 264, the rotating shaft 266 is rotatably arranged in the sealing cylinder 261, the top of the rotating shaft 266 passes through the top of the sealing cylinder 261 and is coaxially connected with the transverse bevel gear 268, one end of the rotating rod 265 passes through one side of the smelting furnace 1 and is coaxially connected with the vertical bevel gear 267, and the vertical bevel gear 267 is meshed and connected with the transverse bevel gear 268, the driving gear 269 is sleeved on the rotating shaft 266, and the driving gear 269 is meshed and connected with the driven gear 262.

[0049] Specifically, while the hydraulic cylinder 231 drives the movable rod 232 to perform reciprocating lifting and lowering motions, the movable rod 232 also drives the spur rack 263 to perform reciprocating lifting and lowering motions, so that the spur rack 263 drives the rotating rod 265 and the vertical bevel gear 267 to rotate through the linkage gear 264 meshing with it, so as to drive the rotating shaft 266 and the driving gear 269 to rotate through the transverse bevel gear 268 meshing with the vertical bevel gear 267, and then drive the driven gear 262 meshing with it to rotate through the driving gear 269, so as to drive the dynamic grinding ring 25 to rotate through the driven gear 262, thereby realizing the grinding operation of the aluminum block through the mutual cooperation of the dynamic grinding ring 25 and the fixed grinding ring 24.

[0050] In one embodiment of the present application, Figure 1-Figure 4 As shown, the stirring mechanism 3 may include a plurality of connecting rods 301 , a plurality of stirring blades 302 and a blocking ring 303 .

[0051] Among them, the retaining ring 303 is sleeved on the outer peripheral surface of the fixed grinding ring 24, and an annular groove is arranged between the retaining ring 303 and the inner wall of the smelting furnace 1, a plurality of connecting rods 301 are respectively located in the annular groove, and one end of the plurality of connecting rods 301 are respectively fixedly connected to the dynamic grinding ring 25, a plurality of stirring blades 302 are respectively located below the fixed grinding ring 24, and a plurality of stirring blades 302 are respectively fixedly connected to the other end of the connecting rod 301.

[0052] It should be noted that the retaining ring 303 described in this embodiment is to prevent the aluminum block falling on the top of the fixed grinding ring 24 from sliding directly through the annular groove, so as to ensure that the aluminum block can be effectively ground by the passive grinding ring 25 and the fixed grinding ring 24.

[0053] Specifically, while the dynamic grinding ring 25 rotates, multiple connecting rods 301 drive multiple stirring blades 302 to circulate around the fixed tube 21 in the smelting furnace 1, so that the aluminum liquid and aluminum blocks are stirred by the multiple stirring blades 302, so that the temperature distribution in the aluminum liquid is more uniform, and the precipitation of the aluminum blocks can be effectively reduced.

[0056] Specifically, the multiple first one-way valves 401 and the second one-way valves 405 are always in an open state, and during the smelting process of the aluminum material, the two discharge valves 403 are respectively in a closed state, so that the aluminum liquid and the aluminum block can enter the fixed tube 21 through the multiple first one-way valves 401, so that the piston plate 22 can feed the aluminum block.

[0057] When the aluminum material is completely melted into aluminum liquid, the relevant personnel open the two discharge valves 403 to discharge the aluminum liquid. At this time, a part of the aluminum liquid is discharged naturally through the branch pipe 404 and the discharge pipe 402. At the same time, the relevant personnel also drive the piston plate 22 to perform reciprocating lifting motion through the reciprocating lifting mechanism 23. In the process of the piston plate 22 moving upward, the piston plate 22 extracts part of the aluminum liquid into the fixed pipe 21 through multiple first one-way valves 401, and applies pressure to the aluminum liquid in the fixed pipe 21 when the piston plate 22 descends, so that it passes through the second one-way valve 405 and the discharge valve 403 into the discharge pipe 402 and is discharged, so as to achieve the purpose of effectively improving the aluminum liquid discharge efficiency.
