Recycled aluminum primarily appears in the form of aluminum alloys, and aluminum cracking furnaces are used in the scrap aluminum smelting process.

[0003] At present, the feed port of a large aluminum alloy melting furnace is set on the side of the furnace body, so that the recycled aluminum raw materials can be manually put into the furnace cavity of the aluminum alloy melting furnace when adding materials. Manually pouring the raw materials into the feed port is not only complicated, time-consuming and labor-intensive, but also has low work efficiency. Long-term feeding will also cause the heat in the furnace body to be lost quickly, affecting the melting effect of the aluminum material in the furnace. At the same time, the frequent opening and closing of the existing gate structure will cause problems such as thermal expansion and contraction deformation of the gate, which will not only deteriorate the insulation effect, but also limit the size of the gate to reduce the deformation problem, making it more inconvenient to put in aluminum materials, which is not conducive to enterprise production.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1-4 As shown, a feeding gate structure includes:

[0030] Applied to the furnace body 6, the furnace body 6 is provided with a feed inlet 61;

[0031] A feed frame 1 is provided on the furnace body 6 , and a feed port 11 matching the feed inlet 61 is provided on the feed frame 1 ;

[0032] The gate mechanism is provided on the feed frame 1, and the gate mechanism includes two movable frames 4, the movable frames 4 are slidably provided on the feed frame 1, and sealing gate plates 5 are mounted on the movable frames 4. The sealing gate plates 5 on the two movable frames 4 are used to match the feed port 11 on the feed frame 1;

[0033] A driving mechanism 2 is connected to the two movable frames 4, and is used to drive the two movable frames 4 to move relative to each other in the horizontal direction along the feed frame 1 to open and close the feed port 11;

[0034] Among them, a hanging component 7 is provided on the sealing gate plate 5, and the sealing gate plate 5 is connected to the movable frame 4 through the hanging component 7. The hanging component 7 drives the sealing gate plate 5 to move up and down along the vertical direction of the movable frame 4 to perform a sealing operation on the feed port 11.

[0035] The feed port 11 on the feed frame 1 of the present invention is arranged on the feed inlet 61 on the furnace body 6, and the sealing gate plates 5 on the two movable frames 4 are matched with the feed port 11. The driving mechanism 2 drives the two movable frames 4 to move relative to each other in the horizontal direction along the feed frame 1. At the same time, the hanging component 7 drives the sealing gate plates 5 to move up and down along the vertical direction of the movable frame 4. The feed port 11 is sealed under the action of the deadweight of the sealing gate plates 5. The operation is simple, effectively preventing the heat of the aluminum material cracking from diffusing outward, improving the sealing and heat insulation effect of the feeding gate, and effectively maintaining the temperature in the aluminum material cracking furnace from dissipating from the feed port 11, thereby ensuring the temperature in the furnace; at the same time, the hanging component 7 is used to separate the movable frame 4 from the sealing gate plates 5. Compared with the method of directly driving the gate, the weight of the sealing gate plates 5 is effectively reduced. By reducing the weight of the movable frame 4, there is no need to limit the weight of the sealing gate plates 5, and the size of the sealing gate plates 5 can be effectively increased.

[0036] In one embodiment of the present invention, mounting seats 41 are provided on both sides of the movable frame 4, roller frames are provided on the mounting seats 41, and movable rollers 42 are provided on the roller frames. A guide frame 58 is provided on the feed frame 1, and a guide rail 43 is provided on the guide frame 58. A track groove 44 matching the movable roller 42 is provided on the guide rail 43, and the movable roller 42 slides in the track groove 44.

[0037] Specifically, a track groove 44 matching the moving roller 42 is provided on the guide rail 43, and the moving roller 42 slides in the track groove 44. The track groove 44 can guide the movement of the moving frame 4, improve the movement accuracy of the sealing gate plate 5, and ensure the sealing effect of the sealing gate plate 5.

[0038] In one embodiment of the present invention, guide frames 58 are provided on both sides of the sealing gate 5, support rollers 59 are provided on the guide frames 58, slide rails 57 matching the support rollers 59 are provided on the feed frame 1, guide grooves are provided on the support rollers 59, and the guide grooves on the support rollers 59 are clamped on the slide rails 57.

[0039] Specifically, the guide groove on the supporting roller 59 is clamped on the slide rail 57, which can quickly and stably drive the upwind gate to open and close, with high working efficiency and stable operation. At the same time, the movable frame 4 and the sealing gate 5 are relatively separated and guided by two sets of tracks, which reduces the structural wear of the traditional single-track movable metal frame embedded in the insulation layer and improves the service life.

[0040] In one embodiment of the present invention, the hanging component 7 includes a hanging frame 71, a guide groove 72 is provided on the hanging frame 71, the center line of the guide groove 72 is perpendicular to the horizontal direction, and a guide rod 73 is provided on the guide frame 74 on the sealing gate plate 5. The guide rod 73 is passed through the guide groove 72, and the sealing gate plate 5 is driven by the guide rod 73 to reciprocate along the guide groove 72.

[0041] In one embodiment of the present invention, a sealing groove 591 matching the support roller 59 is provided on the slide rail 57, and the support roller 59 enters the sealing groove 591 along the slide rail 57 to drive the sealing gate plate 5 to move toward the feed port 11 to cover the feed port 11.

[0042] Specifically, driven by the movable frame 4, the supporting roller 59 slides along the sealing groove 591 onto the slide rail 57. Due to the hanging component 7 provided between the sealing gate plate 5 and the feed frame 1, the guide rod 73 moves upward along the guide groove 72, thereby driving the sealing gate plate 5 to move upward synchronously, so that a certain separation gap is formed between the sealing gate plate 5 and the feed port 11, thereby preventing the sealing gate plate 5 from interfering with other structures.

[0043] When the support roller 59 enters the sealing groove 591 along the slide rail 57, due to the hanging component 7 provided between the sealing gate 5 and the feed frame 1, the guide rod 73 moves downward along the guide groove 72. Driven by the gravity of the sealing gate 5, the sealing gate 5 moves downward synchronously, so that the sealing gate 5 moves toward the feed inlet 11 and covers the feed inlet 11.

[0044] By using the sealing groove 591 in conjunction with the hanging component 7, the feed port 11 can be opened or closed under the force of gravity of the sealing gate plate 5. At the same time, the hanging component 7 is used to separate the movable frame 4 from the sealing gate plate 5. Compared with the method of directly driving the gate, the weight of the sealing gate plate 5 is effectively reduced. By reducing the weight of the movable frame 4, there is no need to limit the weight of the sealing gate plate 5 and the thermal insulation layer 52 thereon, and the size of the sealing gate plate 5 can be effectively increased.

[0045] The driving motor 24 on the driving assembly synchronously drives the chain 25 to rotate, thereby realizing fast and stable driving of the mobile frame 4, effectively ensuring the driving of the sealing gate plate 5, and ensuring the sealing and heat preservation effect of the sealing gate plate 5.

[0046] In one embodiment of the present invention, the sealing gate 5 includes a sealing frame 51, and a thermal insulation layer 52 is evenly arranged on the bottom of the sealing frame 51. The thermal insulation layer 52 is hung on the sealing frame 51 through a hanging part 53. An insulation gap 54 is set between adjacent thermal insulation layers 52. The hanging part 53 can be a fastener such as a bolt.

[0047] The heat-insulating layer 52 is mounted on the sealing frame 51 via the mounting member 53 . Only the heat-insulating layer 52 that needs to be maintained needs to be replaced, which reduces maintenance difficulty and saves costs.

[0048] Specifically, a heat-insulating layer 52 is evenly provided at the bottom of the sealing frame 51. The heat-insulating layer 52 can insulate the furnace body 6 to prevent heat from overflowing from the furnace and at the same time avoid affecting the temperature in the furnace. The heat-insulating layer 52 is hung on the sealing frame 51 through a hanging part 53. When the supporting force of the sealing frame 51 is sufficient, the size of the sealing gate 5 can be effectively increased. Compared with the existing method of embedding the heat-insulating layer 52 in the metal frame, a gap is formed between the heat-insulating layer 52 and the metal frame due to the thermal expansion and contraction when opening and closing the feed port 11, which may cause heat overflow at the least and damage and deformation of the metal frame, affecting the overall heat processing. An insulation pad is provided between the sealing frame 51 and the heat-insulating layer 52 to separate them. The two are relatively separated. At the same time, the hanging method can prevent the thermal expansion and contraction of the temperature in the furnace from affecting the sealing frame 51. At the same time, the size of the sealing gate 5 can be effectively increased while improving the strength of the metal frame, and the range of use is wide.

[0049] In one embodiment of the present invention, a sealing frame is provided on the sealing gate 5, and a heat-insulating sealing layer 55 is provided on the sealing frame. When the sealing gate 5 seals the feed port 11, the heat-insulating sealing layers 55 on the two sealing gates 5 are pressed tightly, and an assembly gap 56 is provided between the two sealing frames 51.

[0050] The thermal insulation sealing layer 55 is arranged on the thermal insulation layer 52. Since an insulation gap 54 is arranged between adjacent thermal insulation layers 52, when the thermal insulation sealing layer 55 is not elastic, this insulation gap 54 can also serve as a deformation space for the thermal insulation sealing layer 55 to ensure the sealing effect of the sealing gate 5.

[0051] Specifically, while the sealing gate 5 seals the feed port 11, the thermal insulation sealing layers 55 on the two sealing gates 5 are pressed tightly. The thermal insulation sealing layers 55 are made of elastic material. When the thermal insulation sealing layers 55 are pressed tightly, the two will undergo a certain deformation, making the two sides fit more tightly, ensuring the sealing performance of the entire equipment and meeting the requirements of temperature calibration in the furnace. There is an assembly gap 56 between the two sealing frames 51, so that the two thermal insulation sealing layers 55 can be fully pressed together to avoid mutual interference that causes the thermal insulation sealing layers 55 to be unable to fit tightly. The thickness of the thermal insulation sealing layer 55 is the same as the thickness of the thermal insulation layer 52, ensuring the thermal insulation consistency of the entire sealing gate 5.

[0052] In one embodiment of the present invention, a support frame 3 is provided on the feed frame 1, and a feed port 31 is provided on the support frame 3. The feed port 31 is located directly above the feed port 11, and the projection area of ​​the feed port 31 on the feed port 11 is less than or equal to the area of ​​the feed port 11. A sealing strip 32 is provided around the edge of the feed port 11.

[0053] Specifically, when it is necessary to add aluminum material to the aluminum cracking chamber, the silo loaded with aluminum material is aligned with the feed port 31 on the support frame 3, and the discharge position of the silo is pressed against the sealing strip 32 to achieve a sealed connection between the silo and the Galio gate structure, thereby preventing the material from being scattered and the flue gas from overflowing through the silo and the support frame 3, thereby ensuring the safety of aluminum material processing. At the same time, the sealed connection can also effectively prevent heat overflow and improve the melting efficiency of the aluminum material. The projection area of ​​the feed port 31 on the feed port 11 is less than or equal to the area of ​​the feed port 11, that is, the feed port 31 is slightly smaller than the feed port 11, which is the best solution. The aluminum material in the silo can be completely dropped into the furnace, thereby avoiding problems such as gate interference caused by aluminum material splashing, thereby ensuring the normal operation of the equipment.

[0054] In one embodiment of the present invention, a fixing groove is provided at the edge of the feed port 11, a sealing strip is provided in the fixing groove, a sealing protrusion is provided on the movable frame 4, the sealing protrusion is arranged opposite to the sealing strip, and the sealing gate 5 seals the feed port 11 while the sealing protrusion is pressed against the sealing strip.

[0055] Specifically, the sealing gate plate 5 moves toward the feed port 11 to cover the feed port 11, and at the same time the sealing protrusion is pressed against the sealing strip to seal and insulate the edges of the sealing gate plate 5 and the feed port 11, which can further ensure the sealing effect of the feed port 11 and avoid affecting the temperature fluctuation of the furnace body 6.

[0056] In one embodiment of the present invention, the driving mechanism 2 includes two driving components, which are respectively driven and connected to the two movable frames 4. The driving components include a driving seat 21, a driving shaft 23 is provided on the driving seat 21, and driving sprockets 22 are provided on both sides of the driving shaft 23. An auxiliary frame 27 is provided on the auxiliary frame 27, and an auxiliary sprocket 26 is provided on the auxiliary frame 27. The driving sprocket 22 and the auxiliary sprocket 26 are linked by a chain 25. The driving shaft 23 is driven and connected to the driving motor 24. The movable frame 4 is connected to the chain 25 through a connecting plate. The driving motor 24 drives the chain 25 on the driving sprocket 22 to rotate and drives the two sides of the movable frame 4 to move synchronously. The driving motors 24 on the two driving components synchronously drive the chain 25 to move so that the two sealing gates 5 move relative to or in opposite directions, so that the sealing gates 5 on them open and close the feed port 11.

[0057] Specifically, the two drive components are respectively connected to the two mobile frames 4, and the drive motors 24 on the two drive components synchronously drive the chain 25 to rotate, thereby driving the two mobile frames 4 to move in opposite directions or relative directions, driving the sealing gate 5 on the mobile frame 4 to open or close the feed port 11 to add materials, thereby realizing fast and stable driving of the mobile frame 4, high working efficiency and stable operation. At the same time, the mobile frame 4 is connected to the chain 25 through a connecting plate. The chain 25 drives the mobile frame 4 to move in a high-temperature environment and will not transfer heat to the drive motor 24 and other drivers, thereby improving the service life of the driver. Compared with driving methods such as cylinders or oil cylinders, it will cause heat to be conducted into the cylinder body along the piston rod, causing it to deform or be damaged.

[0058] Usage process

[0059] When it is necessary to add aluminum material to the aluminum cracking chamber, the silo loaded with aluminum material is aligned with the feed port 31 on the support frame 3, and the discharge position of the silo is pressed against the sealing strip 32 to achieve a sealed connection between the silo and the Galio gate structure, thereby preventing the material from being scattered and the smoke from overflowing through the silo and the support frame 3, ensuring the safety of aluminum material processing. At the same time, the sealed connection can also effectively prevent heat overflow and improve the melting efficiency of the aluminum material. After the silo is aligned with the feed port 31, the two drive assemblies are respectively connected to the two mobile frames 4, and the drive motors 24 on the two drive assemblies synchronously drive the chain 25 to rotate. Since the mobile frame 4 is connected to the chain 25 through the connecting plate, the two mobile frames 4 are driven to move, and the moving roller 42 on the mobile frame 4 is moved. Sliding in the track groove 44 allows the two moving frames 4 to move smoothly in opposite directions. At the same time, driven by the moving frame 4, the supporting roller 59 slides along the sealing groove 591 to the slide rail 57. Due to the hanging component 7 set between the sealing gate 5 and the feed frame 1, the guide rod 73 moves upward along the guide groove 72, thereby driving the sealing gate 5 to move upward synchronously, so that there is a certain separation gap between the sealing gate 5 and the feed port 11 to avoid interference between the sealing gate 5 and other structures. At the same time, the opening of the feed port 11 separates the sealing protrusion from the sealing strip, and the driving motor 24 on the driving assembly continues to drive the chain 25 to rotate until the sealing gate 5 on the moving frame 4 is driven to fully open the feed port 11 for feeding;

[0060] When the aluminum material is added to the aluminum material cracking chamber, the driving motors 24 on the two driving components synchronously drive the chains 25 to rotate. Since the mobile frame 4 is connected to the chain 25 through the connecting plate, the two mobile frames 4 are driven to move. The moving rollers 42 on the mobile frame 4 slide in the track groove 44, so that the two mobile frames 4 move smoothly in the relative directions. When the supporting roller 59 enters the sealing groove 591 along the slide rail 57, due to the hanging component 7 set between the sealing gate 5 and the feeding frame 1, the guide rod 73 moves downward along the guide groove 72. Movement, driven by the gravity of the sealing gate 5, the sealing gate 5 moves downward synchronously, so that the sealing gate 5 moves toward the feed port 11 to cover the feed port 11, until the heat insulating sealing layers 55 on the two sealing gates 5 are tightly pressed and the sealing protrusions are tightly pressed against the sealing strip, thereby achieving thermal insulation sealing of the aluminum material cracking furnace body 6. Multiple sealing structures can effectively prevent the heat of aluminum material cracking from diffusing outward, improve the sealing and heat insulation effect of the feeding gate, and effectively maintain the temperature in the aluminum material cracking furnace from dissipating from the feed port 11, thereby ensuring the temperature in the furnace.
