Description

Technical Field

[0001] This utility model relates to the field of aluminum material processing technology, and specifically to a feeding gate structure. Background Technology

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. Recycled aluminum mainly appears in the form of aluminum alloys, and the aluminum pyrolysis furnace is the equipment used in the scrap aluminum smelting process of recycled aluminum.

[0003] Currently, the feed inlet of large aluminum alloy smelting furnaces is located on the side of the furnace body. This allows for the manual feeding of recycled aluminum raw materials into the furnace cavity. Manually pouring the raw materials into the feed inlet is not only complex, time-consuming, and labor-intensive, but also inefficient. Prolonged feeding also causes rapid heat loss from the furnace, affecting the melting effect of the aluminum. Furthermore, the frequent opening and closing of the existing gate structure leads to problems such as thermal expansion and contraction deformation, which not only reduces the heat preservation effect but also limits the gate size to prevent deformation, further hindering aluminum feeding and negatively impacting production.

[0018] In one embodiment of the present invention, a support frame is provided on the feeding frame, and a feeding port is provided on the support frame.

[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 and implement the present invention. However, the embodiments are not intended to limit the present invention.

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

[0030] It is applied to the furnace body 6, which is provided with a feeding inlet 61;

[0031] A feeding frame 1 is disposed on the furnace body 6, and the feeding frame 1 is provided with a feeding port 11 that matches the feeding inlet 61;

[0032] A gate mechanism is provided on the feeding frame 1. The gate mechanism includes two movable frames 4, which are slidably mounted on the feeding frame 1. A sealing gate plate 5 is hung on the movable frame 4. The sealing gate plates 5 on the two movable frames 4 are used to match the feed inlet 11 on the feeding frame 1.

[0033] The drive mechanism 2 is driven to drive the two movable frames 4. The drive mechanism 2 is used to drive the two movable frames 4 to move relative to each other in the horizontal direction along the feeding frame 1 to open and close the feeding port 11.

[0034] The sealing gate 5 is provided with a hanging component 7. The sealing gate 5 is connected to the movable frame 4 through the hanging component 7. The hanging component 7 drives the sealing gate 5 to move up and down along the vertical direction of the movable frame 4 to seal the feed inlet 11.

[0035] The feed inlet 11 on the feed frame 1 of this utility model is set on the feed inlet 61 on the furnace body 6. The sealing gate 5 on the two moving frames 4 is matched with the feed inlet 11. The drive mechanism 2 drives the two moving 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 5 to move up and down in the vertical direction along the moving frame 4. Under the action of the self-weight of the sealing gate 5, the feed inlet 11 is sealed. The operation is simple and effectively prevents the heat of aluminum pyrolysis from spreading outward, improves the sealing and heat insulation effect of the feeding gate, and effectively maintains that the temperature inside the aluminum pyrolysis furnace will not be lost from the feed inlet 11, thus ensuring the temperature inside the furnace. At the same time, the hanging component 7 is used to separate the moving frame 4 from the sealing gate 5. Compared with the method of directly driving the gate, the weight of the sealing gate 5 is effectively reduced. The weight of the moving frame 4 is reduced, so there is no need to limit the weight of the sealing gate 5, which can effectively increase the size of the sealing gate 5.

[0036] In one embodiment of this utility model, mounting seats 41 are provided on both sides of the movable frame 4, roller frames are provided on the mounting seats 41, movable rollers 42 are provided on the roller frames, guide frames 58 are provided on the feeding frame 1, guide rails 43 are provided on the guide frames 58, and track grooves 44 that match the movable rollers 42 are provided on the guide rails 43, and the movable rollers 42 slide in the track grooves 44.

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

[0038] In one embodiment of the present invention, guide frames 58 are provided on both sides of the sealing gate 5, and support rollers 59 are provided on the guide frames 58. The feeding frame 1 is provided with a slide rail 57 that matches the support rollers 59. The support rollers 59 are provided with guide grooves, and the guide grooves on the support rollers 59 are engaged with the slide rails 57.

[0039] Specifically, the guide groove on the support roller 59 is engaged on the slide rail 57, which can quickly and stably drive the reverse wind gate to open and close, resulting in high working efficiency and stable operation. At the same time, the relative separation between the moving frame 4 and the sealing gate 5 adopts two sets of track guides, which reduces the structural wear of the traditional single-track moving metal frame embedded in the insulation layer and improves the service life.

[0040] In one embodiment of this utility model, the mounting component 7 includes a mounting frame 71, on which a guide groove 72 is provided. The center line of the guide groove 72 is perpendicular to the horizontal direction. A guide rod 73 is provided on the guide frame 74 of the sealing gate 5. The guide rod 73 passes through the guide groove 72, and the sealing gate 5 reciprocates along the guide groove 72 under the drive of the guide rod 73.

[0041] In one embodiment of the present invention, the slide rail 57 is provided with a sealing groove 591 that matches the support roller 59. The support roller 59 enters the sealing groove 591 along the slide rail 57 to drive the sealing gate 5 to move toward the feed inlet 11 to cover the feed inlet 11.

[0042] Specifically, driven by the movable frame 4, the support roller 59 slides along the sealing groove 591 onto 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 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 feeding port 11, avoiding interference between the sealing gate 5 and other structures.

[0043] When the support 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. Under the gravity of the sealing gate 5, the sealing gate 5 moves downward synchronously, so that the sealing gate 5 moves towards the feeding port 11 to cover the feeding port 11.

[0044] The sealing groove 591 is used in conjunction with the hanging component 7 to open or close the feed inlet 11 under the gravity of the sealing gate 5. At the same time, the hanging component 7 separates the moving frame 4 from the sealing gate 5. Compared with the method of directly driving the gate, the weight of the sealing gate 5 is effectively reduced. The weight of the moving frame 4 is reduced, so there is no need to limit the weight of the sealing gate 5 and the heat insulation layer 52 on it, which can effectively increase the size of the sealing gate 5.

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

[0046] In one embodiment of the present invention, the sealing gate 5 includes a sealing frame 51, and a heat insulation layer 52 is uniformly provided at the bottom of the sealing frame 51. The heat insulation layer 52 is hung on the sealing frame 51 by a hanging member 53. A heat insulation gap 54 is provided between adjacent heat insulation layers 52. The hanging member 53 can be a fastener such as a bolt.

[0047] The thermal insulation layer 52 is mounted on the sealing frame 51 by the mounting bracket 53. Only the corresponding thermal insulation layer 52 needs to be replaced, which reduces the maintenance difficulty and saves costs.

[0048] Specifically, a heat insulation layer 52 is evenly provided at the bottom of the sealing frame 51. The heat insulation layer 52 can insulate the furnace body 6, preventing heat from escaping from the furnace and avoiding affecting the temperature inside the furnace. The heat insulation layer 52 is hung on the sealing frame 51 by the hanging component 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 insulation layer 52 into the metal frame, the thermal expansion and contraction of the opening and closing of the feed port 11 causes gaps between the heat insulation layer 52 and the metal frame. This can cause heat to escape or damage and deformation of the metal frame, affecting the overall heat processing. The sealing frame 51 and the heat insulation layer 52 are separated by a heat insulation pad. The two are relatively separated. At the same time, the hanging method can avoid the thermal expansion and contraction of the furnace temperature from affecting the sealing frame 51. It can also effectively increase the size of the sealing gate 5 while improving the strength of the metal frame, and has a wide range of applications.

[0049] In one embodiment of this utility model, a sealing frame is provided on the sealing gate 5, and a heat insulation sealing layer 55 is provided on the sealing frame. While the sealing gate 5 seals the feed inlet 11, the heat insulation sealing layers 55 on the two sealing gates 5 are pressed together, and there is an assembly gap 56 between the two sealing frames 51.

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

[0051] Specifically, while the sealing gate 5 seals the feed inlet 11, the heat insulation sealing layers 55 on the two sealing gates 5 are pressed together. The heat insulation sealing layers 55 are made of elastic material. When the heat insulation sealing layers 55 are pressed together, 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 furnace temperature calibration. There is an assembly gap 56 between the two sealing frames 51 so that the two heat insulation sealing layers 55 can be fully pressed together and avoid mutual interference that would cause the heat insulation sealing layers 55 to not fit tightly. The thickness of the heat insulation sealing layer 55 is the same as the thickness of the heat insulation layer 52, ensuring the heat insulation consistency of the entire sealing gate 5.

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

[0053] Specifically, when aluminum needs to be added to the aluminum pyrolysis chamber, the hopper containing the aluminum is aligned with the inlet 31 on the support frame 3, and the outlet of the hopper is pressed against the sealing strip 32 to achieve a sealed connection between the hopper and the Galio gate structure. This prevents material spillage and flue gas from overflowing between the hopper and the support frame 3, ensuring the safety of aluminum processing. The sealed connection also effectively prevents heat leakage and improves the melting efficiency of the aluminum. The optimal solution is for the inlet 31 to have a projected area less than or equal to that of the inlet 11, i.e., the inlet 31 to be slightly smaller than the inlet 11. This allows the aluminum in the hopper to fall completely into the furnace, avoiding problems such as aluminum splashing causing gate interference and ensuring normal operation of the equipment.

[0054] In one embodiment of this utility model, a fixing groove is provided on the edge of the feed inlet 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 inlet 11 while the sealing protrusion abuts against the sealing strip.

[0055] Specifically, the sealing gate 5 moves toward the feed inlet 11 to cover the feed inlet 11, while the sealing protrusion abuts against the sealing strip, thereby sealing and insulating the edges of the sealing gate 5 and the feed inlet 11, which can further ensure the sealing effect of the feed inlet 11 and avoid affecting the temperature fluctuation of the furnace body 6.

[0056] In one embodiment of this utility model, the driving mechanism 2 includes two driving components, which are respectively drivenly connected to two movable frames 4. Each driving component includes a driving base 21, a driving shaft 23 is provided on the driving base 21, and driving sprockets 22 are provided on both sides of the driving shaft 23. An auxiliary frame 27 is provided on the feeding frame 1, and an auxiliary sprocket 26 is provided on the auxiliary frame 27. The driving sprockets 22 and the auxiliary sprockets 26 are connected by a chain 25. The driving shaft 23 is drivenly connected to a 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, causing the two sides of the movable frame 4 to move synchronously. The driving motors 24 on the two driving components drive the chain 25 to move synchronously, causing the two sealing gates 5 to move relative to each other or in opposite directions, so that the sealing gates 5 on them can open and close the feed inlet 11.

[0057] Specifically, the two drive components are respectively connected to the two moving frames 4. The drive motors 24 on the two drive components synchronously drive the chain 25 to rotate, thereby causing the two moving frames 4 to move in opposite or relative directions. This causes the sealing gate 5 on the moving frame 4 to open or close the feed port 11 for feeding or closing, achieving fast and stable drive of the moving frame 4. The working efficiency is high and the operation is stable. At the same time, the moving frame 4 is connected to the chain 25 through the connecting plate. The chain 25 drives the moving frame 4 to move in a high-temperature environment without transferring heat to the drive motor 24 and other drives, thus improving the service life of the drives. Compared with the drive methods of cylinders or hydraulic cylinders, which cause heat to be conducted to the cylinder body along the piston rod, causing deformation or damage.

[0058] Usage process

[0059] When aluminum needs to be added to the aluminum pyrolysis chamber, the hopper containing the aluminum is aligned with the inlet 31 on the support frame 3, and the outlet of the hopper is pressed against the sealing strip 32 to achieve a sealed connection between the hopper and the Galio gate structure. This prevents material spillage and fumes from overflowing between the hopper and the support frame 3, ensuring the safety of aluminum processing. The sealed connection also effectively prevents heat leakage and improves the melting efficiency of the aluminum. After the hopper is aligned with the inlet 31, the two drive components are respectively connected to the two moving frames 4. The drive motors 24 on the two drive components synchronously drive the chain 25 to rotate. Since the moving frames 4 are connected to the chain 25 through connecting plates, this drives the two moving frames 4 to move. The moving rollers 42 on the moving frames 4... The sliding within the track groove 44 allows the two moving frames 4 to move smoothly in opposite directions. Simultaneously, driven by the moving frames 4, the support roller 59 slides along the sealing groove 591 onto the slide rail 57. Due to the hanging component 7 provided between the sealing gate 5 and the feeding 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 feeding port 11, avoiding interference between the sealing gate 5 and other structures. At the same time, the opening of the feeding port 11 causes the sealing protrusion to separate from the sealing strip. The drive motor 24 on the drive assembly continues to drive the chain 25 to rotate until the sealing gate 5 on the moving frame 4 fully opens the feeding port 11 for feeding.

[0060] When aluminum is added to the aluminum pyrolysis chamber, the drive motors 24 on the two drive components synchronously drive the chain 25 to rotate. Since the moving frame 4 is connected to the chain 25 through the connecting plate, it drives the two moving frames 4 to move. The moving rollers 42 on the moving frame 4 slide in the track groove 44, allowing the two moving frames 4 to move smoothly in opposite directions. When the support 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. Under the influence of gravity, the sealing gate 5 moves downward synchronously, causing it to move towards the feed inlet 11 to cover it until the heat insulation sealing layer 55 on both sealing gates 5 is pressed together and the sealing protrusion is pressed together with the sealing strip. This achieves heat preservation and sealing of the aluminum pyrolysis furnace body 6. The multiple sealing structures can effectively prevent the heat from aluminum pyrolysis from spreading outward, improve the sealing and heat insulation effect of the feeding gate, and effectively maintain the temperature inside the aluminum pyrolysis furnace from being lost from the feed inlet 11, thus ensuring the furnace temperature.
