Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and in particular to a feeding device for aluminum alloy smelting. Background Technology

[0002] With the advancement of the "dual carbon" goals and the increasing demand for resource recycling, aluminum alloy recycling and reuse has become an important direction for industry development. The smelting process is the core link in aluminum alloy recycling, which requires the precise feeding of recycled aluminum alloy granules into the furnace to ensure the initial composition of the molten aluminum is stable, providing qualified raw materials for subsequent forming and processing.

[0003] Existing aluminum alloy smelting feeding devices mostly adopt a fixed height structure design, which lacks height adaptability and cannot flexibly match the differences in inlet height of different furnace models. When the feeding position is misaligned, it is easy to cause material spillage, or it is necessary to disassemble and adjust the parts to achieve adaptation, which seriously affects the efficiency of continuous production. Furthermore, the coordination between weighing and feeding is poor. Most devices need to weigh the material on an independent platform first, and then send it to the feeding mechanism through a transfer process. The transfer process is prone to weight loss or proportion deviation, making it difficult to ensure the accuracy of the actual amount of material fed into the furnace. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a feeding device for aluminum alloy smelting, which aims to improve the existing aluminum alloy smelting feeding device method, which cannot flexibly match the differences in inlet height of different types of furnaces, and has poor coordination between weighing and feeding links, and is prone to weight loss or proportion deviation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for aluminum alloy smelting, comprising a frame, slide rails on both inner walls of the frame, a movable frame slidably connected to the inner wall of the frame, a hopper fixedly connected inside the movable frame, the hopper including a discharge port, an electric discharge valve installed on the discharge port, a chute fixedly connected to the bottom end of the movable frame, the hopper communicating with the chute, a weighing component slidably connected to the inner side of the frame at the bottom end of the chute, a lifting device at the bottom end of the weighing component, and the lifting device fixedly connected to the bottom of the frame.

[0006] Preferably, the weighing assembly includes a support plate and four weighing sensors. Slider 2 is provided on both sides of the support plate. The support plate is slidably connected to the frame through slider 2 and slide rail. The four weighing sensors are fixedly installed at the top four corners of the support plate.

[0007] Preferably, the lifting device is a hydraulic cylinder, and the piston rod of the lifting device is fixedly connected to the bottom end of the support plate.

[0008] Preferably, the electric discharge valve, lifting device, and weighing sensor are all electrically connected to an external controller via wires.

[0009] Preferably, the chute includes a feed inlet and a second discharge outlet. The feed inlet is connected to the first discharge outlet, and the second discharge outlet is connected to the feed end of the furnace. A chute support is fixedly installed at the bottom of the chute, and the bottom of the chute support overlaps with the weighing component.

[0010] Preferably, sliders are fixedly provided on both sides of the movable frame, and the movable frame is slidably connected to the frame through sliders and slide rails.

[0011] Preferably, the frame of the mobile frame is welded with several reinforcing ribs.

[0012] Preferably, a number of evenly distributed support legs are fixedly installed at the bottom of the frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model utilizes the sliding cooperation between the frame slide rail and the moving frame, combined with the lifting device to drive the weighing component to rise and fall. This allows for flexible adjustment of the hopper and chute heights, precisely adapting to different furnace inlets and preventing material spillage due to height misalignment. It eliminates the need for frequent disassembly and adjustment, significantly improving production efficiency. The hopper and chute are directly connected, with the chute overlapping the weighing component, integrating weighing and feeding processes. This eliminates material transfer steps, effectively removing transfer errors and ensuring accurate input. The weighing component independently bears the weight of the chute, hopper, and material, without bearing the frame's own weight, reducing range redundancy and minimizing environmental interference. This significantly improves weighing accuracy and stability, reducing calibration frequency.

[0015] 2. In this utility model, the movable frame is equipped with a slider and a slide rail, which makes the lifting process smooth and without jamming. The reinforcing rib design on the frame can enhance the overall structural rigidity and adapt to the impact load of recycled aluminum materials. The electric discharge valve works in conjunction with the weighing component to facilitate automatic opening after the target weight is reached, reducing the intensity of manual operation. The connection relationship between each component is simple. The overlapping or fixed structure of the chute, hopper and weighing component is easy to disassemble and maintain, and can adapt to the long-term use needs of complex environments such as high temperature and dust in the workshop.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 An embodiment of this utility model provides a feeding device for aluminum alloy smelting, including a frame 1. Slide rails 11 are provided on the inner walls of both sides of the frame 1. A movable frame 2 is slidably connected to the inner wall of the frame 1. A hopper 3 is fixedly connected inside the movable frame 2. The hopper 3 includes a discharge port 31. An electric discharge valve 32 is installed on the discharge port 31. A chute 4 is fixedly connected to the bottom end of the movable frame 2. The hopper 3 communicates with the chute 4. A weighing component is slidably connected to the inner side of the frame 1 at the bottom end of the chute 4. A lifting device 6 is provided at the bottom end of the weighing component. The lifting device 6 is fixedly connected to the bottom of the frame 1.

[0024] The weighing assembly includes a support plate 5 and four load cells 7. Sliding blocks 51 are installed on both sides of the support plate 5, and the support plate 5 is slidably connected to the frame 1 via the sliding blocks 51 and slide rails 11. The four load cells 7 are fixedly installed at the four corners of the top of the support plate 5. The lifting device 6 is a hydraulic cylinder, and its piston rod is fixedly connected to the bottom end of the support plate 5. The electric discharge valve 32, the lifting device 6, and the load cells 7 are all electrically connected to an external controller via wires.

[0025] The chute 4 includes a feed inlet 41 and a discharge outlet 42. The feed inlet 41 is connected to the discharge outlet 31, and the discharge outlet 42 is connected to the furnace feed end. A chute support 43 is fixedly installed at the bottom of the chute 4, and the bottom of the chute support 43 overlaps with the weighing component. Sliding blocks 22 are fixedly installed on both sides of the movable frame 2. The movable frame 2 is slidably connected to the frame through the sliding blocks 22 and the slide rail 11. Several reinforcing ribs 21 are welded on the frame of the movable frame 2. Several evenly distributed support legs 8 are fixedly installed at the bottom of the frame 1.

[0026] The specific implementation method is as follows: In the initial state, the movable frame 2 is slidably connected to the slide rail 11 on the inner wall of the frame 1 through the sliders 22 on both sides. The hopper 3 is fixed inside the movable frame 2. The chute 4 is fixed to the bottom of the movable frame 2 and its inlet 41 is connected to the outlet 31 of the hopper 3. The chute support 43 at the bottom of the chute 4 is directly attached to the support plate 5 of the weighing component. The support plate 5 of the weighing component is slidably connected to the slide rail 11 of the frame 1 through the sliders 51 on both sides. The bottom end is fixed to the piston rod of the lifting device 6. The whole structure forms a rigid linkage structure of frame 1, slide rail 11, movable frame 2, hopper 3, chute 4, weighing component and lifting device 6.

[0027] When it is necessary to adapt to different furnace inlet heights, the lifting device 6 is activated. Its piston rod extends and retracts, causing the support plate 5 to slide up and down along the slide rail 11. Since the moving frame 2 is connected to the support plate 5 through the chute support 43, the lifting and lowering of the support plate 5 will synchronously drive the moving frame 2, hopper 3 and chute 4 to lift and lower as a whole along the slide rail 11 until the discharge port 42 of the chute 4 is precisely aligned with the feed end of the target furnace. During this process, the cooperation between the slide rail 11 and the slider 22 and slider 51 ensures that the overall lifting and lowering is without deviation. The reinforcing rib 21 on the moving frame 2 enhances the rigidity of the frame and avoids structural deformation caused by the weight of the material or the impact of lifting and lowering.

[0028] During the material feeding stage, after the height adjustment is completed, recycled aluminum material is added to the hopper 3. The weight of the material is transferred to the chute 4 through the hopper 3, and then directly acts on the weighing sensors 7 at the four corners of the top of the support plate 5 through the chute support 43. The four weighing sensors 7 are evenly distributed and can collect the total weight of the hopper 3, chute 4 and material in real time. The weight of the empty hopper and chute 4 is preset to the initial value, and the net weight of the material is accurately measured through signal feedback. When the weighing data reaches the preset feeding amount, the electric discharge valve 32 is started, the discharge port 31 of the hopper 3 is opened, and the material flows into the chute 4 through the feed port 41 under the action of gravity, and then is sent into the furnace from the discharge port 42 along the inclined structure of the chute 4.

[0029] After feeding is completed, the electric discharge valve 32 is closed, and the lifting device 6 can drive the support plate 5 to rise and fall again according to the inlet height of the next furnace, so as to adjust the moving frame 2, hopper 3 and chute 4 to the corresponding positions and enter the next feeding cycle. Throughout the process, the weighing component only bears the weight of the hopper 3, chute 4 and the material, and is completely separated from the weight of the frame 1. The guide rail 11 avoids lateral force interference and ensures stable weighing accuracy. At the same time, the sliding connection and rigid connection design of each component not only ensures the flexibility of lifting, but also meets the long-term stable operation requirements in the high temperature and dust environment of the workshop.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
