Technical Field
[0001] This application relates to the field of aluminum processing technology, and in particular to an automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace. Background Technology
[0002] In the process of recycling aluminum alloy smelting, the feeding of scrap aluminum is a critical step. Traditional manual feeding is labor-intensive and the working environment is relatively dangerous. Therefore, it is necessary to design an automatic scrap aluminum feeding device for aluminum alloy smelting furnace.
[0003] A related automatic scrap aluminum feeding device for an aluminum alloy smelting furnace includes a fixed base, a storage bin, and a conveying assembly. Workers place scrap aluminum in the storage bin, and the scrap aluminum is transported to the smelting furnace for smelting via a conveyor belt.
[0004] However, an existing automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace causes significant splashing when feeding scrap aluminum. This not only poses a safety hazard to workers, but the solidified aluminum blocks after splashing also adhere to other equipment, affecting their normal operation. Utility Model Content
[0005] In order to reduce the problem of a large amount of molten aluminum splashing when the automatic scrap aluminum feeding device is feeding, this application provides an automatic scrap aluminum preheating feeding device for an aluminum alloy smelting furnace.
[0006] This application provides an automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace, which adopts the following technical solution: An automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace includes: A fixed bracket is vertically and fixedly installed on the ground. The storage bin is fixedly mounted on a fixed support. The storage bin has a storage cavity inside, a feed hopper at the top, and a discharge hole on the periphery. The crushing component is rotatably mounted at one end of the storage chamber near the feed hopper, and is used to crush waste aluminum. The heater is fixedly installed on the storage box, and the heating end of the heater extends into the storage cavity. The heater is used to preheat the scrap aluminum. The feeding assembly has one end fixedly mounted on the storage bin and the other end fixedly mounted on the fixed support, extending towards the melting furnace.
[0007] By adopting the above technical solution, the fixed bracket provides installation space for the storage box and feeding component, the storage chamber provides storage space for scrap aluminum, the feeding hopper facilitates workers to put scrap aluminum into the storage box, the crushing component can crush the scrap aluminum fed into the storage chamber through the feeding hopper, so that large-volume scrap aluminum is crushed into smaller pieces, reducing the impact force when scrap aluminum enters the smelting furnace, thereby reducing the degree of splashing of molten aluminum; the feeding component can convey the scrap aluminum in the storage chamber into the smelting furnace, reducing the manual feeding steps of workers, allowing workers to remotely control the scrap aluminum to enter the smelting furnace, reducing the work risk of workers; the heater can heat the crushed scrap aluminum, which can reduce the moisture in the scrap aluminum pieces, reduce the occurrence of instantaneous vaporization and volume expansion of moisture after entering the molten aluminum, reduce the probability of splashing of molten aluminum due to the influence of bubbles, and the heater can also increase the temperature of scrap aluminum, reduce the temperature difference between scrap aluminum and molten aluminum, accelerate the melting speed of scrap aluminum after being added to molten aluminum, and improve the smelting efficiency of the smelting furnace.
[0008] Optionally, the pulverizing components include: A crushing shaft is rotatably mounted on the storage box, and multiple sets of crushing shafts are spaced apart along the inner wall of the storage chamber. The first motor is fixedly installed on the periphery of the storage box. The output end of the first motor passes through the storage box and is fixedly connected to the crushing shaft. Multiple sets of the first motor and the crushing shaft are provided accordingly. The pulverizing blades are fixedly mounted on the pulverizing shaft. Multiple sets of pulverizing blades are spaced apart along the length of the pulverizing shaft, and these multiple sets of pulverizing blades on the pulverizing shaft are arranged alternately.
[0009] By adopting the above technical solution, the rotation of the first motor can drive the crushing shaft to rotate synchronously, and the rotation of the crushing shaft can drive the crushing blades to rotate synchronously. When scrap aluminum is put into the storage chamber through the feed hopper, the smaller scrap aluminum will pass through the gap between the crushing blades and enter the bottom of the storage chamber, while the larger scrap aluminum will be stuck on the crushing blades. The staggered rotation of multiple sets of crushing blades will cut the larger scrap aluminum into smaller pieces, thereby achieving the preliminary treatment of scrap aluminum. This makes the scrap aluminum reach a smaller size before entering the smelting furnace, reducing the impact force of the scrap aluminum entering the smelting furnace on the molten aluminum, thereby reducing the probability of molten aluminum splashing.
[0010] Optional, the feeding components include: The hydraulic telescopic rod is horizontally fixed on the side of the fixed bracket away from the discharge hole, and the telescopic end of the hydraulic telescopic rod extends into the storage cavity. The pusher plate is vertically fixed on the telescopic end of the hydraulic telescopic rod; The feeding channel is fixedly mounted at an angle on a fixed support. The feeding channel is equipped with a feeding chamber, which is connected to the storage chamber through a discharge hole.
[0011] By adopting the above technical solution, the extension of the hydraulic telescopic rod can drive the pusher plate to move closer to the discharge hole. The movement of the pusher plate can push the scrap aluminum in the storage chamber toward the discharge hole. The scrap aluminum enters the feeding chamber through the discharge hole. The inclined setting of the feeding channel allows the scrap aluminum to move along the length of the feeding channel by gravity and slide into the smelting furnace, thus achieving the purpose of automatic scrap aluminum feeding.
[0012] Optionally, a weighing platform is fixedly installed at the bottom of the storage chamber.
[0013] By adopting the above technical solution, the weighing platform allows staff to measure the weight of scrap aluminum inside the storage chamber, thereby controlling the amount of scrap aluminum added into the smelting furnace at one time and reducing the probability of splashing caused by excessive scrap aluminum leading to a violent reaction of molten aluminum.
[0014] Optionally, an electric gate is fixedly installed on the side of the storage bin with the discharge hole.
[0015] By adopting the above technical solution, the electric gate allows staff to remotely control the opening and closing of the discharge port, reducing the speed at which heat in the storage chamber leaves the storage chamber through the discharge port, thereby reducing heat loss during the preheating of scrap aluminum and reducing the energy consumption of the automatic scrap aluminum preheating feeding device.
[0016] Optionally, a cover plate is rotatably installed inside the storage chamber, and a second motor is fixedly installed around the storage box. The output end of the second motor is fixedly connected to the rotation shaft of the cover plate, and two sets of cover plates are symmetrically arranged along the central axis of the width direction of the storage chamber.
[0017] By adopting the above technical solution, the rotation of the second motor can drive the cover plate to rotate synchronously, so that the cover plate can switch between horizontal and vertical states. When the cover plate is in the horizontal state, the cover plate makes the storage cavity form a relatively sealed space, thereby reducing the heat loss in the storage cavity and reducing the energy consumption of the waste aluminum preheating automatic feeding device.
[0018] Optionally, the upper end of the push plate is provided with rounded corners.
[0019] By adopting the above technical solution, the rounded corners can reduce the accumulation of scrap aluminum on the upper part of the pusher plate, thereby reducing the probability of scrap aluminum getting stuck in the gap between the pusher plate and the inner wall of the storage cavity, and reducing the obstruction caused by scrap aluminum to the movement of the pusher plate.
[0020] Optionally, a vibrating block is fixedly installed below the feeding channel, and multiple sets of vibrating blocks are spaced apart along the feeding chamber direction.
[0021] By adopting the above technical solution, the setting of the vibrating block can generate vibration below the feeding channel. Vibration can reduce the occurrence of scrap aluminum getting stuck or accumulating in the feeding chamber, improve the smoothness of scrap aluminum movement in the feeding channel, and improve the working efficiency of the scrap aluminum preheating automatic feeding device.
[0022] An automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace is provided, which includes at least one of the following beneficial technical effects: 1. The fixed bracket provides installation space for the storage box and feeding assembly. The storage chamber provides storage space for scrap aluminum. The feeding hopper facilitates workers to put scrap aluminum into the storage box. The crushing assembly can crush the scrap aluminum fed into the storage chamber through the feeding hopper, breaking large scrap aluminum into smaller pieces, reducing the impact force when the scrap aluminum enters the smelting furnace, thereby reducing the degree of splashing of molten aluminum. The feeding assembly can convey the scrap aluminum in the storage chamber into the smelting furnace, reducing the manual feeding steps for workers and allowing workers to remotely control the scrap aluminum to enter the smelting furnace, reducing the work risk for workers. The heater can heat the crushed scrap aluminum, which can reduce the moisture in the scrap aluminum pieces, reducing the occurrence of instantaneous vaporization and volume expansion of moisture after entering the molten aluminum, reducing the probability of splashing of molten aluminum due to air bubbles. The heater can also increase the temperature of the scrap aluminum, reduce the temperature difference between the scrap aluminum and the molten aluminum, accelerate the melting speed of the scrap aluminum after being added to the molten aluminum, and improve the smelting efficiency of the smelting furnace.
[0023] 2. The rotation of the second motor can drive the cover plate to rotate synchronously, so that the cover plate can switch between horizontal and vertical states. When the cover plate is in the horizontal state, the cover plate makes the storage cavity a relatively sealed space, thereby reducing the heat loss in the storage cavity and reducing the energy consumption of the waste aluminum preheating automatic feeding device.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0027] Combination Figure 1 , Figure 2 and Figure 3 This application discloses an automatic feeding device for preheating scrap aluminum in an aluminum alloy smelting furnace, comprising: a fixed support 44, a storage tank 11, a crushing component 2, a heater 12, and a feeding component 3; the fixed support 44 is vertically fixed on the ground, the storage tank 11 is fixedly mounted on the fixed support 44, the storage tank 11 has a storage cavity 41, the upper end of the storage tank 11 has a feed hopper 13, and the storage tank 11 has a discharge hole 42 on its periphery; the crushing component 2 is rotatably mounted on the storage cavity 41 near the feed hopper 13, and the crushing component 2 is used to crush scrap aluminum; the heater 12 is fixedly mounted on the storage tank 11, and the heating end of the heater 12 extends into the storage cavity 41, and the heater 12 is used to preheat the scrap aluminum; one end of the feeding component 3 is fixedly mounted on the storage tank 11, and the other end of the feeding component 3 is fixedly mounted on the fixed support 44 and extends toward the smelting furnace.
[0028] In this embodiment, the fixed bracket 44 is a cuboid frame, the storage box 11 is a cuboid, the storage cavity 41 is a cuboid, the discharge hole 42 is a cuboid, and the feed hopper 13 is an inverted frustum. Workers can feed scrap aluminum into the storage cavity 41 through the feed hopper 13. The crushing component 2 can crush the scrap aluminum fed into the storage cavity 41 through the feed hopper 13, cutting larger scrap aluminum into smaller scrap aluminum blocks. A weighing platform 14 is fixedly installed at the bottom of the storage cavity 41. The weighing platform 14 can measure the weight of the scrap aluminum that falls to the bottom of the storage cavity 41 after cutting, facilitating workers to control the weight of scrap aluminum fed into the smelting furnace and reducing the risk of excessive scrap aluminum being added. This reduces the probability of splashing due to violent reaction of molten aluminum. Two sets of heaters 12 are symmetrically arranged along the centerline of the storage tank 11. When the heaters 12 are activated, they heat the scrap aluminum placed in the storage chamber 41, reducing moisture on the scrap aluminum, increasing its temperature, and lowering the probability of splashing caused by the expansion of moisture upon entering the molten aluminum. The heaters 12 also increase the temperature of the scrap aluminum, reducing the temperature difference between the scrap aluminum and the molten aluminum, accelerating the melting speed of the scrap aluminum after being added to the molten aluminum, and improving the smelting efficiency of the furnace. An electric gate 15 is fixedly installed on the side of the storage tank 11 with the discharge hole 42. Operators can remotely control the electric gate 15 to control the opening or closing of the discharge hole 42, reducing the risk of splashing in the storage chamber 41. The rate at which internal heat is dissipated through the discharge hole 42 improves the insulation of the storage cavity 41 and reduces the energy loss of the automatic feeding device for preheating waste aluminum. The working principle of the electric gate 15 is existing technology in this field, so the working principle of the electric gate 15 will not be specifically described in this embodiment. A cover plate 16 is rotatably installed inside the storage cavity 41. The cover plate 16 is rectangular. A second motor 17 is fixedly installed around the periphery of the storage box 11. The output end of the second motor 17 is fixedly connected to the rotating shaft of the cover plate 16. The rotation of the second motor 17 can drive the cover plate 16 to rotate around the rotating shaft, thereby driving the second motor 17 to switch between horizontal and vertical states. The cover plate 16 is along the central axis of the width direction of the storage cavity 41. Two sets of covers are symmetrically arranged. When both sets of covers 16 are in a horizontal state, they will separate the end of the storage chamber 41 near the crushing component 2 from the bottom of the storage chamber 41 into two parts, making the storage chamber 41 a relatively sealed space. This reduces the heat loss in the storage chamber 41, reduces the energy consumption of the automatic waste aluminum preheating feeding device, and improves the preheating efficiency of waste aluminum. After the waste aluminum is cut and preheated, the operator starts the feeding component 3, which transports the waste aluminum into the smelting furnace. This reduces the step of manually feeding waste aluminum into the smelting furnace and improves the feeding efficiency of waste aluminum. The operator can remotely control the feeding component 3 to transport waste aluminum, reducing the safety hazards for the operator.
[0029] In practical use, the operator feeds scrap aluminum into the storage chamber 41 through the feed hopper 13. The crushing component 2 is activated and cuts the fed scrap aluminum into smaller scrap aluminum blocks. The cut scrap aluminum blocks fall onto the weighing platform 14. The operator controls the weight of scrap aluminum entering the smelting furnace at one time based on the weight on the weighing platform 14. The operator starts the second motor 17, which rotates the cover plate 16 to a horizontal position. The operator controls the electric gate 15 to close, so that a relatively sealed space is formed in the storage chamber 41. The operator starts the heater 12 to preheat the scrap aluminum. After the scrap aluminum is preheated, the operator controls the electric gate 15 to open and starts the pushing component. The pushing component conveys the preheated scrap aluminum into the smelting furnace, thus completing the automatic feeding process of scrap aluminum.
[0030] Combination Figure 1 , Figure 2 and Figure 3 In one specific embodiment, the crushing component 2 includes: a crushing shaft 22, a first motor 21, and crushing blades 23; the crushing shaft 22 is rotatably mounted on the storage box 11, and multiple sets of the crushing shaft 22 are spaced apart along the inner side wall of the storage cavity 41; the first motor 21 is fixedly mounted on the periphery of the storage box 11, and the output end of the first motor 21 passes through the storage box 11 and is fixedly connected to the crushing shaft 22; multiple sets of the first motor 21 and the crushing shaft 22 are correspondingly mounted; the crushing blades 23 are fixedly mounted on the crushing shaft 22, and multiple sets of the crushing blades 23 are spaced apart along the length direction of the crushing shaft 22; the multiple sets of crushing blades 23 on the multiple sets of crushing shafts 22 are staggered.
[0031] In this embodiment, the crushing shaft 22 is cylindrical. The rotation of the output end of the first motor 21 is not affected by the storage box 11. The rotation of the first motor 21 can drive the crushing shaft 22 to rotate synchronously. The rotation of the crushing shaft 22 can drive the crushing blades 23 to rotate synchronously around the central axis of the crushing shaft 22. The multiple sets of staggered crushing blades 23 rotating in opposite directions can quickly cut the scrap aluminum fed through the feed hopper 13 into small pieces. The volume of the scrap aluminum after cutting is smaller than that before cutting, which reduces the impact force on the molten aluminum when the scrap aluminum enters the smelting furnace, thereby reducing the probability of molten aluminum splashing.
[0032] In actual use, the staff starts the first motor 21. The rotation of the first motor 21 drives the crushing shaft 22 to rotate synchronously. The rotation of the crushing shaft 22 drives the crushing blades 23 to rotate synchronously. Multiple sets of crushing blades 23 work together to cut the input waste aluminum into smaller parts.
[0033] Combination Figure 1 and Figure 2In one specific embodiment, the feeding component 3 includes: a hydraulic telescopic rod 31, a pusher plate 32, and a feeding channel 33; the hydraulic telescopic rod 31 is horizontally fixed on the side of the fixed bracket 44 away from the discharge hole 42, and the telescopic end of the hydraulic telescopic rod 31 extends into the storage cavity 41; the pusher plate 32 is vertically fixed on the telescopic end of the hydraulic telescopic rod 31; the feeding channel 33 is inclinedly fixed on the fixed bracket 44, and a feeding cavity 43 is provided on the feeding channel 33, which is connected to the storage cavity 41 through the discharge hole 42.
[0034] In this embodiment, the fixed end of the hydraulic telescopic rod 31 is fixedly mounted on the fixed bracket 44 via a support block 19. The support block 19 is rectangular, and the pusher plate 32 is also rectangular. The upper end of the pusher plate 32 has rounded corners, which reduces the probability of scrap aluminum accumulating above the pusher plate 32. The extension and retraction of the hydraulic telescopic rod 31 can drive the pusher plate 32 to move synchronously, causing the pusher plate 32 to move along the length of the storage cavity 41. When the pusher plate 32 moves towards the discharge hole 42, it can push the scrap aluminum in the storage cavity 41 toward the discharge hole 42. The scrap aluminum enters the feeding cavity 43 through the discharge hole 42. The feeding channel 33 is inclined, so the scrap aluminum can move along the length of the feeding chamber 43 and slide into the smelting furnace under the action of gravity. A vibrating block 18 is fixedly installed below the feeding channel 33. Multiple sets of vibrating blocks 18 are arranged at intervals along the feeding chamber 43. The vibrating blocks 18 can generate vibration below the feeding channel 33. The vibration can reduce the occurrence of scrap aluminum getting stuck or accumulating in the feeding chamber 43 and improve the smoothness of the movement of scrap aluminum in the feeding channel 33. By using the pusher plate 32 and the feeding channel 33 together, the function of automatic scrap aluminum feeding is realized. Mechanized feeding improves the feeding efficiency of scrap aluminum.
[0035] In practical use, after the preheating of scrap aluminum is completed, the operator controls the hydraulic telescopic rod 31 to extend. The extension of the hydraulic telescopic rod 31 drives the pusher plate 32 to move synchronously. The pusher plate 32 pushes the scrap aluminum in the storage chamber 41 toward the discharge hole 42. The scrap aluminum enters the feeding chamber 43 through the discharge hole 42. The operator activates the vibrating block 18, which can vibrate the feeding channel 33. Under the action of the feeding channel 33 and the vibrating block 18, the scrap aluminum moves along the length of the feeding chamber 43 and slides into the smelting furnace, thus realizing the automatic feeding of scrap aluminum.
[0036] It should be noted that the heater 12, weighing platform 14, electric gate 15, first motor 21, second motor 17, hydraulic telescopic rod 31, and vibrating block 18 are electrically connected to an external power source. The automatic feeding device for preheating scrap aluminum in the aluminum alloy smelting furnace is equipped with a PLC control panel. The PLC control panel is electrically connected to the heater 12, weighing platform 14, electric gate 15, first motor 21, second motor 17, hydraulic telescopic rod 31, and vibrating block 18. The PLC control panel can control the extension and retraction of the hydraulic telescopic rod 31, the rotation of the first motor 21 and the second motor 17, the start of the heater 12, electric gate 15, and vibrating block 18, and the weighing data of the weighing platform 14 can be detected through the PLC control panel.
[0037] The implementation principle of this application is as follows: Workers feed scrap aluminum into the storage chamber 41 through the feed hopper 13. The worker starts the first motor 21, which drives the crushing shaft 22 to rotate synchronously. The crushing shaft 22 then drives the crushing blades 23 to rotate synchronously. The crushing blades 23 cut the fed scrap aluminum into smaller pieces, which fall onto the weighing platform 14. The worker then starts the second motor 17, which drives the cover plate 16 to a horizontal position. The worker then controls the electric gate 15 to close, and the operation... The operator starts the heater 12, which preheats the scrap aluminum. After the scrap aluminum is preheated, the operator controls the electric gate 15 to open and starts the hydraulic telescopic rod 31. The hydraulic telescopic rod 31 extends and drives the pusher plate 32 to move closer to the discharge hole 42. The pusher plate 32 moves and pushes the scrap aluminum in the storage chamber 41 through the discharge hole 42 into the feeding chamber 43. The operator starts the vibrating block 18, which vibrates the feeding channel 33. Under the action of gravity and vibration, the scrap aluminum moves along the length of the feeding chamber 43 and slides into the smelting furnace.
[0038] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
