Description

Technical Field

[0001] This application relates to the technical field of melting furnaces, and in particular to an aluminum alloy melting furnace. Background Technology

[0002] In the aluminum alloy processing industry, aluminum alloy melting furnaces are devices used to heat aluminum alloy raw materials to a molten state, and are widely used in aerospace, automobile manufacturing and other fields. Currently, the feeding process of traditional aluminum alloy melting furnaces mostly relies on manual labor or simple mechanical assistance: when feeding manually, operators need to move the aluminum alloy raw materials to the feeding port at the top of the furnace, which is not only labor-intensive, but also causes the raw materials to scatter and waste; simple mechanical feeding (such as forklifts) is limited by the space around the furnace, making it difficult to accurately feed the raw materials into the feeding port. Especially for large pieces of aluminum alloy raw materials, additional manual cutting is required before feeding, making the process cumbersome and the operation inefficient. Utility Model Content

[0003] In order to improve the problem that the feeding process of aluminum alloy smelting furnaces relies heavily on manual labor or simple mechanical assistance, which is labor-intensive and raw materials are easy to scatter; and that simple mechanical feeding requires additional manual cutting before feeding, resulting in low operating efficiency, this application provides an aluminum alloy smelting furnace.

[0004] This application provides an aluminum alloy melting furnace, which adopts the following technical solution: An aluminum alloy melting furnace includes a fixed base and a furnace body. The furnace body is rotatably mounted on the fixed base. A material inlet is provided at the top of the furnace body. A processing box is installed above the furnace body. A cutting assembly is provided above the processing box. A material discharge channel is provided at the bottom of the processing box. The outlet of the material discharge channel is connected to the material inlet. A lifting assembly is provided on one side of the fixed base. The lifting assembly includes a support frame and a lifting frame for placing a loading trolley. The loading trolley contains aluminum alloy to be processed. A first slide rail and a second slide rail connected to the first slide rail are provided on the support frame. The second slide rail is perpendicular to the first slide rail and is located on the side closer to the furnace body. The lifting frame slides within the first and second slide rails, driving the loading trolley to transport the aluminum alloy to be processed to the processing box.

[0005] By adopting the above technical solution, the fixed base provides a supporting foundation for the furnace body, and the rotatable furnace body facilitates the subsequent pouring and discharge of molten aluminum alloy, thus enhancing flexibility. The material inlet precisely aligns with the material discharge channel at the bottom of the processing box, ensuring that raw materials are transported without spillage. The cutting component above the processing box can pre-process and cut large pieces of aluminum alloy to be processed, eliminating the need for additional manual segmentation and simplifying the process. The lifting component, through the first and second mutually perpendicular slides on the support frame, enables the lifting frame to drive the loading trolley in a continuous vertical lifting and lateral translation motion, smoothly transporting the loading trolley from the ground to the processing box, completing the automatic loading of raw materials. Compared with traditional manual or forklift loading, this structure realizes the entire process of raw material placement, automatic lifting, cutting, and precise furnace entry, significantly improving loading efficiency and raw material utilization while reducing the safety risks associated with manual intervention.

[0006] Optionally, a tapered drain port is provided on the side of the material inlet away from the lifting frame.

[0007] By adopting the above technical solution, the tapered inlet can form a transition structure with a wide inlet and narrow outlet. When the material is poured into the pre-set receiving container in the furnace body, it can be discharged smoothly, reducing waste.

[0008] Optionally, a chain conveying assembly is provided inside the support frame, a movable block is slidably disposed on the first slide rail, the chain conveying assembly drives the movable block to slide, and the other side of the movable block is connected to the lifting frame.

[0009] By adopting the above technical solution, the chain conveyor assembly provides a stable power source for the lifting frame. The chain drive has the characteristics of high transmission accuracy and strong load capacity, which can accurately drive the moving block on the first slide to slide at a uniform speed, thereby driving the lifting frame and the feeding trolley to rise or fall smoothly or move horizontally. At the same time, it is easy to control the feeding speed by adjusting the chain speed, adapt to the conveying needs of aluminum alloy raw materials of different specifications, and improve the stability of equipment operation.

[0010] Optionally, the lifting frame includes a cooperating frame and a guide rod that are configured to cooperate with the feeding trolley. The guide rod is installed on the cooperating frame on the side near the furnace body and is located on the side near the moving block. A guide groove is provided at the bottom of the second slide rail so that the guide rod slides into the second slide rail. The guide rod is slidably configured with the second slide rail so that the feeding trolley transports the aluminum alloy to be processed to the processing box.

[0011] By adopting the above technical solutions, the lifting frame can be precisely matched with the feeding trolley, ensuring that the feeding trolley does not shake or deviate during the lifting process; the guide rod and guide groove cooperate to provide pre-positioning and precise sliding guidance for the lifting frame to enter the second slide: when the lifting frame enters the second slide laterally from the first slide, the guide rod first slides into the guide groove, limiting the lateral displacement deviation of the lifting frame, so that the feeding trolley can be accurately aligned with the feed inlet of the processing box, avoiding the inability of the raw materials to be smoothly fed into the processing box due to the deviation of the lifting frame, and further improving the feeding positioning accuracy.

[0012] Optionally, the bottom of the loading trolley is provided with multiple rollers, and both sides of the loading trolley are provided with snap-fit ​​components. Both sides of the lifting frame are provided with snap-fit ​​grooves for snap-fit ​​connection of the snap-fit ​​components, and the snap-fit ​​grooves are provided one-to-one with the snap-fit ​​components.

[0013] By adopting the above technical solution, multiple rollers allow operators to easily push the trolley on the ground and move the aluminum alloy to be processed to the lifting frame, reducing the intensity of manual handling. The snap-fit ​​parts on both sides of the trolley correspond one-to-one with the snap-fit ​​slots on both sides of the lifting frame, which can fix the trolley on the lifting frame when the lifting frame moves, preventing the trolley from slipping or deviating due to vibration or inertia during vertical lifting or horizontal translation, ensuring the safety and stability of the material transportation process. At the same time, the snap-fit ​​structure is easy to disassemble and assemble, facilitating the quick replacement and maintenance of the loading trolley.

[0014] Optionally, a rotating shaft is provided on both sides of the fixed base, and both rotating shafts are rotatably connected to the furnace body. A power source is provided on one side of the fixed base, and the power source drives one of the rotating shafts to rotate. A rotation space is provided between the furnace body and the bottom of the fixed base.

[0015] By adopting the above technical solution, the rotating shaft provides a fulcrum for the furnace body, ensuring that the furnace body can rotate smoothly around the rotating shaft; the power source can drive the rotating shaft to control the rotation angle and speed of the furnace body. After melting is completed, the molten aluminum alloy can be quickly poured into a designated container by rotating the furnace body. The rotation space between the furnace body and the bottom of the fixed seat provides sufficient range of motion for the furnace body to rotate, avoiding collision between the bottom of the furnace body and the fixed seat, protecting the furnace body structure, and extending the service life of the equipment.

[0016] Optionally, the cutting assembly includes a drive shaft and a driven shaft, which are arranged in parallel and rotatably mounted on the upper part of the processing box. A cutting blade is sleeved on both the drive shaft and the driven shaft. One end of the drive shaft extends out of the processing box and is sleeved and connected to a drive gear. One end of the driven shaft extends out of the processing box and is sleeved and connected to a driven gear. The drive gear and the driven gear are meshed and connected. The other end of the drive gear is connected to a first driving member to drive the drive shaft and the driven shaft to rotate. The first driving member is mounted on the processing box.

[0017] By adopting the above technical solution, the drive shaft and driven shaft of the cutting component are arranged in parallel, and the drive gear and driven gear mesh to achieve synchronous rotation of the drive shaft and driven shaft: when the first driving component drives the drive shaft to rotate, the drive gear drives the driven gear to rotate synchronously in the opposite direction, so that the cutting blade on the drive shaft and the driven shaft form a counter-shearing motion. Compared with single-axis cutting, counter-shearing can cut large pieces of aluminum alloy raw materials more efficiently, reduce the extrusion deformation of raw materials during cutting, and reduce the wear speed of the cutting blade. In addition, the cutting component is integrated into the upper part of the processing box, and the raw materials can fall directly into the processing box after cutting without intermediate transfer, further shortening the raw material processing cycle.

[0018] Optionally, the furnace body is provided with a stirring assembly, which includes a second driving component and a stirring shaft. The second driving component is installed at the bottom of the furnace body and drives the stirring shaft. The stirring shaft is located inside the furnace body and is provided with multiple stirring blades.

[0019] By adopting the above technical solution, the stirring assembly can uniformly stir the molten aluminum alloy. The second driving component drives the stirring shaft to rotate, which in turn drives multiple stirring blades on the stirring shaft to rotate. This can break up the temperature stratification of the molten aluminum alloy in the furnace, making the temperature uniform in all areas of the furnace and avoiding insufficient melting of raw materials due to local low temperatures. The stirring blades can break up and float impurities and bubbles in the molten aluminum alloy, which is convenient for subsequent impurity cleaning, improves the purity of the molten aluminum alloy, and thus ensures the quality stability of downstream processed products.

[0020] Optionally, a heating layer is provided inside the furnace body, and a heat insulation layer is provided between the outer wall of the furnace body and the heating layer.

[0021] By adopting the above technical solutions, the heating layer can directly heat the aluminum alloy raw materials inside the furnace, ensuring that the raw materials can quickly reach the melting temperature; the insulation layer can effectively reduce the loss of heat from the furnace to the external environment, reduce energy consumption during the heating process, save energy costs, avoid excessively high temperatures on the outer wall of the furnace, reduce the risk of operators being accidentally burned, and at the same time protect the external structure of the furnace from high temperatures, extending the overall service life of the furnace.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This smelting furnace achieves integrated operation of raw material handling, automatic lifting, cutting, and precise furnace feeding by improving the slide transmission of the lifting components and the pre-processing function of the cutting components. This reduces the strength limitations of traditional manual feeding and the space limitations of forklift feeding, improves work efficiency, and avoids spillage and waste during raw material cutting and conveying, thus improving raw material utilization. 2. The lifting frame, guide rod, second slide rail, and guide trough work together to form a conveying direction of bearing positioning, guiding sliding in, and channel conveying: the supporting frame supports and fixes the loading trolley, and the guide rod and guide trough work together to guide the lifting frame to accurately enter the second slide rail, driving the loading trolley to move in a direction to the processing box, thus completing the raw material conveying.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0029] This application discloses an aluminum alloy melting furnace, referring to... Figure 1 and Figure 2 The aluminum alloy melting furnace includes a fixed base 1 and a furnace body 2. The furnace body 2 is rotatably mounted on the fixed base 1. A material inlet 21 is provided on the top of the furnace body 2. A processing box 3 is installed above the furnace body 2. A cutting assembly 31 is provided above the processing box 3. A material discharge channel is provided at the bottom of the processing box 3. The outlet of the material discharge channel is connected to the material inlet 21. A lifting assembly 4 is provided on one side of the fixed base 1. The lifting assembly 4 includes a support frame 41 and a lifting frame 43 for placing a loading trolley 5. The loading trolley 5 contains aluminum alloy to be processed. A first slide rail 411 and a second slide rail 412 connected to the first slide rail 411 are provided on the support frame 41. The second slide rail 412 is perpendicular to the first slide rail 411 and is located on the side close to the furnace body 2. The lifting frame 43 slides within the first slide rail 411 and the second slide rail 412, driving the loading trolley 5 to transport the aluminum alloy to be processed to the processing box 3.

[0030] In this aluminum alloy melting furnace, the fixed base 1 provides an installation platform for the furnace body 2 and limits the rotation range of the furnace body 2 to prevent it from shifting during melting or unloading. Its structure must be adapted to the weight and rotation requirements of the furnace body 2 to ensure the overall stability of the equipment during operation. The furnace body 2 bears the raw material heating and melting process; by rotating and mounting on the fixed base 1, its angle can be adjusted after melting to pour the molten aluminum alloy into a designated container for convenient unloading. The top material inlet 21 serves as the channel for the aluminum alloy to be processed into the furnace body 2, precisely connecting with the unloading channel of the processing box 3. The processing box 3 receives the aluminum alloy raw material processed by the cutting component 31 at the top, and guides the raw material to the material inlet 21 of the furnace body 2 through the unloading channel below. Its internal space can organize the cut raw material, preventing it from accumulating and clogging the channel.

[0031] The cutting component 31 pre-processes and cuts large pieces of aluminum alloy, dividing them into smaller pieces that fit the feeding channel and can be accommodated in the furnace body 2, eliminating the need for additional manual processing using the cutting equipment. Its cutting action can be coordinated with the material conveying speed of the lifting component 4, eliminating the traditional process of manually handling large pieces of material, cutting them separately, and then handling and feeding them again, thus improving work efficiency. At the same time, it avoids operational errors and material loss during manual cutting, improves material utilization, and reduces the safety risks to operators due to close contact with the cutting equipment.

[0032] In the lifting assembly 4, the first slide rail 411 on the support frame 41 is set vertically and the second slide rail 412, which is set horizontally and close to the furnace body 2, forms an L-shaped conveying path, providing a sliding track for the lifting frame 43. The lifting frame 43 is used to place the feeding trolley 5, which can slide in the slide rail, driving the feeding trolley 5 to complete the conveying of ground material picking, vertical lifting, and horizontal translation to the processing box 3. No manual or forklift intervention is required, realizing the automated and precise conveying of raw materials, which is suitable for dense layout scenarios with multiple furnaces in parallel.

[0033] The loading trolley 5 serves as a container for aluminum alloys to be processed. It can hold aluminum alloy raw materials of different specifications (including large pieces) inside, making it easy to move and pick up materials on the ground. Its structure is adapted to the lifting frame 43, and it can be stably placed on the lifting frame 43. It moves synchronously with the lifting frame 43 to accurately transport the raw materials to the processing box 3.

[0034] This aluminum alloy smelting furnace integrates the traditional, scattered processes of raw material handling, cutting, feeding, smelting, and unloading into automated operations through the coordinated work of the lifting component 4 for conveying raw materials, the cutting component 31 for pretreatment, the processing box 3 for feeding through the connection between the material feeding channel and the processing box 3, the fixed base 1 for support, and the furnace body 2 for melting and rotation. It realizes the fully automated operation of the aluminum alloy to be processed from ground material collection to melting into the furnace, without the need for a large amount of manual intervention, thereby improving the overall smelting efficiency and adapting to the needs of large-scale production.

[0035] refer to Figure 2 and Figure 3 A chain conveyor assembly is installed inside the support frame 41. A movable block 42 is slidably mounted on the first slide rail 411. The chain conveyor assembly drives the movable block 42 to slide. The other side of the movable block 42 is connected to the lifting frame 43. The chain conveyor assembly is existing technology and provides a continuous and stable driving force for the sliding of the movable block 42. Through its own chain meshing transmission, the power is accurately transmitted to the movable block 42. At the same time, the sliding speed of the movable block 42 can be controlled by adjusting the transmission speed to adapt to the conveying needs in different scenarios.

[0036] The first slide rail 411 defines the movement path of the moving block 42, ensuring that the moving block 42 slides only along a preset direction, preventing lateral deviation or swaying during movement. Its inner wall structure must be compatible with the moving block 42 to reduce frictional resistance during sliding, ensuring smooth movement and improving power transmission efficiency. The moving block 42 receives power from the chain conveyor assembly and converts it into a driving force for the lifting frame 43 to slide. Its structure must be compatible with both the chain conveyor assembly and the lifting frame 43 to ensure lossless power transmission. The lifting frame 43 slides along the first slide rail 411 with the moving block 42, driving the loading trolley 5 to complete the preset conveying path. Its structure must be compatible with the loading trolley 5 to ensure that the loading trolley 5 does not slip or sway during movement.

[0037] refer to Figures 1-5 The lifting frame 43 includes a mating frame 431 and a guide rod 432 that cooperate with the loading trolley 5. The guide rod 432 is installed on the mating frame 431 on the side near the furnace body 2 and is located on the side near the moving block 42. A guide groove 4121 is provided at the bottom of the second slide rail 412 so that the guide rod 432 can slide into the second slide rail 412. The guide rod 432 and the second slide rail 412 are slidably set so that the loading trolley 5 can transport the aluminum alloy to be processed to the processing box 3. The mating frame 431 provides a placement platform for the loading trolley 5, limiting the lateral deviation and vertical sway of the loading trolley 5 during movement; at the same time, it serves as the mounting base for the guide rod 432, fixing the guide rod 432 in a preset position to ensure the precise docking of the guide rod 432 and the second slide rail 412. The guide rod 432 guides the lifting frame 43 into the second slide rail 412. Its shape is adapted to the guide groove 4121 at the bottom of the second slide rail 412. It can slide into the second slide rail 412 along the guide groove 4121, providing directional guidance for the sliding of the lifting frame 43. At the same time, through its own rigid structure, it helps to maintain the movement stability of the lifting frame 43 in the second slide rail 412.

[0038] The second slide rail 412 limits the lateral movement range of the lifting frame 43; its internal structure is adapted to the guide rod 432 and the lifting frame 43 to ensure that the lifting frame 43 slides smoothly in the slide rail without any jamming or sticking, and finally guides the lifting frame 43 to drive the loading trolley 5 to dock with the processing box 3. The guide groove 4121 is a pre-positioning groove for the guide rod 432 to slide into the second slide rail 412, guiding the guide rod 432 to accurately enter the second slide rail 412, while limiting the lateral displacement of the guide rod 432 during the sliding process, ensuring that the guide rod 432 always moves along the direction of the guide groove 4121, thereby driving the lifting frame 43 to slide in a directional manner.

[0039] refer to Figure 3 and Figure 4 The loading trolley 5 is equipped with multiple rollers 51 at its bottom, and locking components 52 are provided on both sides of the loading trolley 5. The lifting frame 43 has locking grooves 433 on both sides for locking the locking components 52. The locking grooves 433 are corresponding to the locking components 52. The rollers 51 convert the sliding friction between the loading trolley 5 and the ground into rolling friction, reducing the resistance when the trolley is pushed on the ground. This significantly reduces the force required by the operator to push the loading trolley 5, making the process of picking up materials from the ground and transferring them to the lifting frame 43 more convenient and reducing the burden of manual handling. At the same time, the even distribution of multiple rollers 51 maintains the balance of the trolley when it moves on the ground and prevents the trolley from tilting.

[0040] The snap-fit ​​component 52 can be embedded in the snap-fit ​​groove 433 to form a fixed connection, restricting the lateral and vertical displacement of the loading trolley 5 on the lifting frame 43, and ensuring the stability of the loading trolley 5 during vertical lifting and lateral translation. At the same time, the snap-fit ​​component 52 must have a certain degree of elasticity or rigidity to ensure that it is not easy to fall off after being embedded. The snap-fit ​​groove 433 serves as a receiving and limiting groove for the snap-fit ​​component 52. The groove structure limits the position of the snap-fit ​​component 52, thereby fixing the loading trolley 5. The inside of the groove must be precisely adapted to the shape of the snap-fit ​​component 52 to ensure that there is no loose gap after the snap-fit ​​component 52 is embedded, and to ensure that the loading trolley 5 can quickly and accurately dock with the lifting frame 43, reducing the time spent manually adjusting the position of the trolley.

[0041] refer to Figure 1 and Figure 7 The cutting assembly 31 includes a drive shaft 311 and a driven shaft 312. The drive shaft 311 and the driven shaft 312 are arranged in parallel and are both rotatably mounted on the upper part of the processing box 3. A cutting blade 313 is sleeved on both the drive shaft 311 and the driven shaft 312. One end of the drive shaft 311 extends out of the processing box 3 and is sleeved and connected to a drive gear 314. One end of the driven shaft 312 extends out of the processing box 3 and is sleeved and connected to a driven gear 315. The drive gear 314 and the driven gear 315 are meshed and connected for transmission. The other end of the drive gear 314 is connected to a first driving member 316 to drive the drive shaft 311 and the driven shaft 312 to rotate. The first driving member 316 is mounted on the processing box 3.

[0042] The first driving component 316 is the power source 12 of the cutting assembly 31. It is connected to the drive gear 314 and can output stable rotational power to drive the drive gear 314 to rotate the drive shaft 311. At the same time, the rotational speed of the cutting blade 313 can be controlled by adjusting the output speed to adapt to the cutting needs of aluminum alloy raw materials with different hardness and thickness. The drive shaft 311 is the power transmission shaft of the cutting assembly 31. One end is connected to the first driving component 316 to receive power, and the other end is linked with the driven shaft 312 through gear engagement. The cutting blade 313 is sleeved on the shaft, which can drive the cutting blade 313 to rotate synchronously and provide active cutting force for cutting raw materials. At the same time, the shaft is rotated and set on the upper part of the processing box 3 to ensure the stability of the shaft during rotation.

[0043] The driving gear 314 and driven gear 315 mesh to form a transmission connection, transmitting the rotational power of the driving shaft 311 to the driven shaft 312, while ensuring that their rotational directions are opposite and their speeds are matched. The tooth profile and meshing accuracy of the gears must meet the power transmission requirements to avoid slippage or jamming during transmission. The driven shaft 312 receives the power transmitted from the driving shaft 311 through the meshing of the driven gear 315 and the driving gear 314, driving itself and the cutting blade 313 to rotate. Its rotation direction is opposite to that of the driving shaft 311, forming a counter-shearing engagement with the cutting blade 313 on the driving shaft 311, which can more easily cut the raw material and avoid deformation of the raw material due to unidirectional force. The parallel arrangement of the structure ensures that the spacing between the two sets of cutting blades 313 is uniform, improving the cutting quality.

[0044] The cutting blade 313 achieves the cutting action through the contact between the blade and the raw material. The blade structure needs to be adapted to the characteristics of aluminum alloy raw material to ensure that it is not easy to chip or wear during the cutting process. At the same time, the spacing between the two sets of cutting blades 313 needs to match the subsequent feeding requirements to control the size of the raw material after cutting.

[0045] refer to Figure 1 and Figure 8The furnace body 2 is equipped with a stirring assembly 22, which includes a second drive component 221 and a stirring shaft 222. The second drive component 221 is installed at the bottom of the furnace body 2 and drives the stirring shaft 222, which is located inside the furnace body 2. Multiple stirring blades 223 are mounted on the stirring shaft 222. The second drive component 221 is the power source 12 of the stirring assembly 22, providing stable rotational power to directly drive the stirring shaft 222. The output speed can be adjusted according to smelting requirements to adapt to the stirring intensity requirements of different melting stages. The stirring shaft 222 receives power and transmits it to the stirring blades 223 inside the furnace body 2, ensuring that the stirring blades 223 rotate synchronously with the drive component, avoiding interruption or lag in power transmission. The rigid structure of the stirring shaft 222 prevents deformation under high temperature and high load conditions, ensuring that the stirring blades 223 always stir along a preset trajectory, preventing incomplete stirring due to shaft misalignment and improving stirring uniformity.

[0046] The stirring blades 223 are in direct contact with the molten aluminum alloy inside the furnace body 2. The rotation of the blades propels the molten aluminum alloy to flow, breaking the static state of the molten raw material. The distribution of multiple stirring blades 223 needs to cover different areas inside the furnace body 2 to ensure no dead zones in the stirring. At the same time, the stirring blades 223 can break up impurities and air bubbles in the molten raw material, causing impurities to float to the surface for easy subsequent cleaning, thereby improving the purity of the molten aluminum alloy.

[0047] The furnace body 2 has a heating layer inside, and an insulation layer between the outer wall of the furnace body 2 and the heating layer. The heating layer converts electrical energy, fuel energy, etc. into heat energy and directly transfers heat to the aluminum alloy raw material inside the furnace body 2, providing a continuous heat input for the raw material to be heated from a solid state to a molten state. Its heating area must cover the main space inside the furnace body 2 to ensure that the raw material is heated evenly. The insulation layer can reduce the heat generated by the heating layer from the furnace body 2 to the external environment, and at the same time prevent the outer wall of the furnace body 2 from becoming too hot due to heat absorption. Its material must have good heat insulation performance to ensure that the heat is confined to the inside of the furnace body 2 as much as possible.

[0048] Rotating shafts 11 are installed on both sides of the fixed base 1, and both rotating shafts 11 are rotatably connected to the furnace body 2. A power source 12 is installed on the outer side of the fixed base 1, which drives the rotating shafts 11 to rotate. A rotation space is provided between the furnace body 2 and the bottom of the fixed base 1. The rotating shafts 11 provide a stable rotation fulcrum for the furnace body 2. The shaft structure must have sufficient rigidity to support the weight of the furnace body 2 and the molten aluminum alloy inside, while ensuring that the furnace body 2 rotates without deviation or jamming. The power source 12 can output stable rotational power to drive the rotating shafts 11 to rotate the furnace body 2 synchronously. At the same time, by adjusting the output speed and direction, the rotation speed and angle of the furnace body 2 can be precisely controlled, which can prevent the furnace body 2 from rotating too fast and causing the molten aluminum alloy to splash, or the rotation angle from being too small and causing incomplete discharge, thus ensuring a safe and efficient discharge process.

[0049] The rotation space provides ample range of motion for the furnace body 2 to rotate, preventing the bottom of the furnace body 2 from colliding or rubbing against the fixed base 1 during rotation; the size of the space must be adapted to the maximum rotation angle of the furnace body 2 to ensure that the furnace body 2 can rotate to a position that meets the material discharge requirements, protect the structural integrity of the furnace body 2 and the fixed base 1, and extend the service life of the components.

[0050] A tapered inlet 211 is provided on the side of the feed inlet 21 away from the lifting frame 43. The feed inlet 21 provides an entrance for the raw material into the furnace body 2. The size of its opening must be adapted to the outlet of the feeding channel and the internal space of the furnace body 2 to ensure that the raw material can pass through smoothly without blockage. The tapered inlet 211 has a wide inlet and a narrow end, which guides and gathers the poured molten aluminum alloy. Its inner wall must be kept smooth to reduce frictional resistance when the raw material falls, guide it to pour into the designated container, and reduce raw material waste and subsequent cleaning work.

[0051] The implementation process of an aluminum alloy melting furnace according to an embodiment of this application is as follows: The operator places the aluminum alloy raw material (including large pieces) to be processed into the loading trolley 5, and pushes the loading trolley 5 to the lifting frame 43, so that the snap-fit ​​pieces 52 on both sides of the loading trolley 5 and the snap-fit ​​grooves 433 on both sides of the lifting frame 43 are snapped into place, thus fixing the loading trolley 5 to the lifting frame 43. Then, the power system of the lifting assembly 4 is started, and the chain conveyor drives the moving block 42 on the first slide rail 411 to slide. The moving block 42 drives the lifting frame 43 to rise vertically along the first slide rail 411. When the lifting frame 43 moves to the connection point with the second slide rail 412, the guide rod 432 on the lifting frame 43 slides into the guide groove 4121 at the bottom of the second slide rail 412. Under the guidance of the guide groove 4121, the lifting frame 43 slides laterally along the second slide rail 412 until the loading trolley 5 is precisely aligned with the feed inlet 21 of the processing box 3, sending the aluminum alloy raw material to be processed into the processing box 3.

[0052] The cutting assembly 31 above the processing box 3 is activated, and the first drive component 316 outputs power, driving the drive shaft 311 to rotate. The drive gear 314 on the drive shaft 311 drives the driven gear 315 on the driven shaft 312 to rotate through meshing transmission, causing the drive shaft 311 and the driven shaft 312 to rotate synchronously in opposite directions. The cutting blades 313 on the drive shaft 311 and the driven shaft 312 rotate with the shaft body, performing counter-shearing on the aluminum alloy raw material to be processed, cutting large pieces of raw material into specifications suitable for subsequent conveying and melting. The cut raw material falls into the processing box 3 under the action of gravity, and is then conveyed to the material inlet 21 at the top of the furnace body 2 through the material discharge channel at the bottom of the processing box 3.

[0053] After being cut, the raw material falls from the outlet of the feeding channel and enters the furnace body 2 through the material inlet 21. Then, the heating layer inside the furnace body 2 is activated, which converts energy into heat energy and transfers heat into the furnace body 2, so that the raw material is gradually heated from a solid state to a molten state. At the same time, the insulation layer between the outer wall of the furnace body 2 and the heating layer prevents heat loss and maintains a stable high-temperature environment inside the furnace body 2, ensuring that the raw material is heated evenly.

[0054] During the raw material melting process, the stirring assembly 22 at the bottom of the furnace body 2 is activated. The second drive component 221 drives the stirring shaft 222 to rotate, and multiple stirring blades 223 on the stirring shaft 222 rotate synchronously with the shaft, stirring the molten aluminum alloy inside the furnace body 2. The stirring blades 223 break up the temperature stratification of the molten raw material, making the temperature of each area inside the furnace body 2 consistent. At the same time, they disperse impurities and air bubbles in the molten raw material, causing the impurities to float to the surface of the molten liquid, facilitating subsequent cleaning and improving the purity of the molten aluminum alloy.

[0055] Once the aluminum alloy raw material is completely melted and meets the preset smelting requirements, the operation of the heating layer and stirring assembly 22 is stopped. The power source 12 on the outer side of the fixed base 1 is started, driving the rotating shafts 11 on both sides inside the fixed base 1 to rotate. The furnace body 2 rotates slowly around the rotating shafts 11. The rotation space between the furnace body 2 and the bottom of the fixed base 1 provides sufficient range of motion for the rotation of the furnace body 2, preventing the bottom of the furnace body 2 from colliding with the fixed base 1. As the rotation angle of the furnace body 2 gradually increases, the molten aluminum alloy inside the furnace body 2 is poured from the constricted outlet 211 of the furnace body 2 into the preset receiving container under the action of gravity, completing the discharge. After the discharge is completed, the power source 12 is started in reverse to return the furnace body 2 to the initial position, waiting for the next round of operation.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
