Description

Technical Field

[0001] This invention relates to the field of smelting furnace technology, specifically a waste aluminum melting furnace. Background Technology

[0002] A tilting rotary furnace is a smelting furnace whose body can rotate slowly and is hydraulically tilted as a whole. It is mainly used for the recycling and smelting of scrap aluminum. During operation, the furnace body rotates at a low speed, which allows the material to be heated evenly and melted completely, reducing metal loss and improving the recovery rate. During discharge, the tilting of the furnace body separates the molten aluminum from the slag.

[0003] Existing tilting rotary smelting furnaces typically require specialized operators to drive forklifts during the melting and discharging processes. These operators use long poles with scrapers at the front to reach into the furnace for work: during melting, the scrapers move to agitate the material; during slag discharge, the scrapers are used to manually limit flow and block slag, preventing molten slag from flowing out with the aluminum. However, because the furnace body is in a continuously tilted dynamic state during discharge, the scraper position needs to be adjusted in real time according to the furnace's posture, making operation cumbersome, difficult to synchronize, and highly dependent on manual labor. Therefore, we propose a waste aluminum melting furnace. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a waste aluminum melting furnace, comprising a base and a deflector frame rotatably mounted on the base. A furnace body is mounted on the deflector frame, which also includes a U-shaped frame. An arc-shaped plate is mounted on the U-shaped frame, with an arc-shaped notch for discharging liquid material. A docking assembly connected to the U-shaped frame is mounted on the deflector frame. The docking assembly drives the U-shaped frame to move, causing the arc-shaped plate to embed into the furnace body opening, thus blocking the liquid material surface and discharging the liquid material through the arc-shaped notch. The arc-shaped plate is a symmetrical split structure, comprising two plates. A deflector connected to the two plates is mounted on the U-shaped frame. The deflector drives each plate to deflect 90 degrees, arranging the two plates in a V-shape to form a support structure for guiding the sliding of an external long rod.

[0005] In some embodiments, an inclined plate is fixedly connected to the top of the U-shaped frame, the inclined plate is connected to the plate body, and a connecting plate is fixedly connected to the bottom of the U-shaped frame. An installation plate is fixedly connected to the deflection frame, and a parallel double-link assembly is provided between the connecting plate and the installation plate. An electric push rod connected to the parallel double-link assembly is provided on the installation plate. When the electric push rod is activated, the parallel double-link assembly drives the arc-shaped plate to be embedded into the furnace body opening.

[0006] In some embodiments, the parallel double linkage assembly includes a shaft 1 rotatably connected to a connecting plate and a mounting plate, a connecting rod 1 fixedly connected between the two shafts 1, a connecting rod 2 parallelly arranged on one side of the connecting rod 1, the two ends of the connecting rod 2 being rotatably connected to the connecting plate and the mounting plate respectively via rotating shafts, and a shaft 2 rotatably connected to the connecting rod 1, the shaft 2 being rotatably connected to the extended end of the electric push rod, and the bottom end of the electric push rod being rotatably connected to the mounting plate via a rotating shaft.

[0007] In some embodiments, the deflecting component includes a portal frame connected to the top of the plate, a shaft three fixedly connected to the portal frame, one end of the shaft three passing through the inclined plate and rotatably connected thereto, a reduction motor fixedly connected to the U-shaped frame, a swing plate one fixedly connected to the output shaft of the reduction motor, a swing plate two fixedly connected to one end of the shaft three, and a connecting rod three rotatably connected between the swing plate one and the swing plate two via a rotating shaft, and starting the reduction motor drives the plate to deflect.

[0008] In some embodiments, a shaft four is fixedly connected to the top of the plate, the shaft four is rotatably connected to the door frame, a rectangular plate is fixedly connected to the inclined plate, and a right-angled trapezoidal block is fixedly connected to one end of the rectangular plate, which is used to push the plate during the plate deflection process so that it deflects and tilts.

[0009] In some embodiments, an L-shaped limiting block is fixedly connected to one side of the plate, the L-shaped limiting block contacts and abuts against the door frame, and a torsion spring is sleeved on the shaft four, with both ends of the torsion spring fixedly connected to the shaft four and the door frame respectively.

[0010] This invention has at least the following beneficial effects:

[0011] This device uses docking components to drive a U-shaped frame and an arc-shaped plate to embed into the furnace opening, which can effectively block the material surface, ensuring that the molten aluminum is stably discharged only from the arc-shaped notch while the molten slag is blocked inside. This eliminates the need for real-time adjustment by a manual forklift, simplifying the material discharge operation. At the same time, the arc-shaped plate can be driven by deflection components to form a V-shaped support and guide structure, which can provide stable support and guidance for the external long rod, improving the stability and reliability of long rod operations and making it safer and more convenient to use.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8 This invention provides a technical solution: a waste aluminum melting furnace, including a base 1 and a deflector frame 11 rotatably mounted on the base 1. A furnace body 12 is mounted on the deflector frame 11. The furnace also includes a U-shaped frame 2 mounted on the deflector frame 11. An arc-shaped plate 3 is mounted on the U-shaped frame 2. An arc-shaped notch 7 for discharging liquid material is provided on the arc-shaped plate 3. A docking assembly 4 connected to the U-shaped frame 2 is provided on the deflector frame 11. The docking assembly 4 is used to drive the U-shaped frame 2 to move, so that the arc-shaped plate 3 is embedded in the opening of the furnace body 12 to block the liquid material surface and discharge the liquid material through the arc-shaped notch 7. The arc-shaped plate 3 is a symmetrical split structure, including two plates 5. A deflector 6 connected to the two plates 5 is provided on the U-shaped frame 2. The deflector 6 is used to drive the two plates 5 to deflect 90 degrees respectively, so that the two plates 5 are arranged in a V-shape to form a support structure for sliding guidance of an external long rod.

[0023] Specifically, in the initial state, the arc-shaped plate 3 is not embedded in the opening of the furnace body 12, and the opening of the furnace body 12 is completely open, facilitating the operator to add material into the furnace. After the material is added, the electric push rod 17 drives the connecting rod 19 and the connecting rod 21 to deflect, which drives the U-shaped frame 2 fixed to the connecting plate 14 to move, so that the arc-shaped plate 3 is embedded in the opening of the furnace body 12. Then, the reduction motor 25 is started to drive the swing plate 26 to deflect, which drives the swing plate 27 and the shaft 24 to rotate via the connecting rod 28. This, in turn, drives the gate frame 23 and the plate 5 to deflect. During the deflection process, the plate 5 is limited and pushed by the right-angled trapezoidal block 32, causing it to rotate relative to the gate frame 23. Finally, the two plates 5 are arranged in a V-shape, forming a support structure for the external long rod to slide and guide. At this time, the operator can place the long rod on the forklift between the two plates 5, and use the V-shaped support structure to guide and limit the long rod, reducing the swaying of the long rod and reducing the probability of the scraper scraping against the inner wall of the furnace body 12. After the material is completely melted, the operator manipulates the forklift to detach the scraper from the furnace body 12, and restarts the geared motor 25 to drive the two plates 5 to reset and combine to form a complete arc plate 3. When the furnace body 12 is tilted to discharge material, the arc plate 3 can block the material surface, and the aluminum liquid can be discharged stably only through the arc-shaped notch 7, avoiding the slag from flowing out with the aluminum liquid.

[0024] In summary, this device drives the U-shaped frame 2 and the arc plate 3 to embed into the furnace opening through the docking component 4, which can effectively block the material surface and ensure that the aluminum liquid is stably discharged only from the arc-shaped notch 7 while the molten slag is blocked inside. There is no need for real-time adjustment by manual forklift, simplifying the material discharge operation. At the same time, the arc plate 3 can be driven by the deflector 6 to form a V-shaped support and guide structure, which can provide stable support and guidance for the external long rod, improve the stability and reliability of long rod operation, and make it safer and more convenient to use.

[0025] A sloping plate 13 is fixedly connected to the top of the U-shaped frame 2. The sloping plate 13 is connected to the plate body 5. A connecting plate 14 is fixedly connected to the bottom of the U-shaped frame 2. An mounting plate 15 is fixedly connected to the deflection frame 11. A parallel double linkage assembly 16 is provided between the connecting plate 14 and the mounting plate 15. An electric push rod 17 connected to the parallel double linkage assembly 16 is provided on the mounting plate 15. The electric push rod 17 is used to drive the arc plate 3 to be embedded into the opening of the furnace body 12 through the parallel double linkage assembly 16.

[0026] The parallel double-link assembly 16 includes a first shaft 18 rotatably connected to a connecting plate 14 and a mounting plate 15, respectively. A first link 19 is fixedly connected between the two first shafts 18. A second link 21 is arranged parallel to one side of the first link 19, and both ends of the second link 21 are rotatably connected to the connecting plate 14 and the mounting plate 15 via rotating shafts. A second shaft 22 is rotatably connected to the first link 19, and the second shaft 22 is rotatably connected to the extended end of an electric push rod 17. The bottom end of the electric push rod 17 is rotatably connected to the mounting plate 15 via a rotating shaft.

[0027] Specifically, when the arc-shaped plate 3 is inside the opening of the furnace body 12, the upper ends of connecting rod 19 and connecting rod 21 are tilted towards one side of the furnace body 12, forming a gap between the edge of the arc-shaped plate 3 and the inner wall of the opening of the furnace body 12, thus avoiding motion interference. During the process of starting the electric push rod 17 to drive the arc-shaped plate 3 out of the opening of the furnace body 12, the ends of connecting rod 19 and connecting rod 21 first rise relative to the ground and then fall, thereby driving the arc-shaped plate 3 to first rise relative to the inner wall of the opening of the furnace body 12, and then move outward out of the opening of the furnace body 12 and continue to fall. This effectively avoids motion interference and allows the arc-shaped plate 3 to completely avoid the opening of the furnace body 12, ensuring that the furnace opening is fully open.

[0028] The deflecting component 6 includes a portal frame 23 connected to the top of the plate 5. A shaft 24 is fixedly connected to the portal frame 23. One end of the shaft 24 passes through the inclined plate 13 and is rotatably connected to it. A geared motor 25 is fixedly connected to the U-shaped frame 2. A swing plate 26 is fixedly connected to the output shaft of the geared motor 25. A swing plate 27 is fixedly connected to one end of the shaft 24. A connecting rod 28 is rotatably connected between the swing plate 26 and the swing plate 27 through a rotating shaft. When the geared motor 25 is started, the swing plate 26 is deflected, which in turn drives the connecting rod 28 to push the swing plate 27 to deflect, thereby causing the shaft 24 and the portal frame 23 to deflect, and thus causing the plate 5 to deflect.

[0029] A shaft 29 is fixedly connected to the top of the plate 5. The shaft 29 is rotatably connected to the door frame 23. A rectangular plate 31 is fixedly connected to the inclined plate 13. A right-angled trapezoidal block 32 is fixedly connected to one end of the rectangular plate 31. It is used to push the plate 5 during the deflection process so that it deflects and tilts.

[0030] An L-shaped limiting block 33 is fixedly connected to one side of the plate 5. When the plate 5 is perpendicular to the ground, the L-shaped limiting block 33 contacts and abuts against the door frame 23. A torsion spring 34 is sleeved on the shaft 4 29. The two ends of the torsion spring 34 are fixedly connected to the shaft 4 29 and the door frame 23 respectively. When the plate 5 deflects, the torsion spring 34 is subjected to force and torsion to provide self-recovering elastic force.
