Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid refining equipment, and specifically to an aluminum liquid refining device. Background Technology

[0002] In the aluminum alloy processing industry, aluminum refining is a key process for improving the quality of aluminum materials. Currently, this refining and purification process is mostly done manually. Specifically, workers hold a refining pipe and insert it into the high-temperature molten aluminum, passing in inert gas and refining agents. They then manually stir the pipe to achieve the purification effect. However, this method has certain drawbacks. For example, the refining effect is affected by factors such as the worker's skill level and physical strength, which can easily lead to unstable product quality. Furthermore, workers need to work at the high-temperature furnace opening for extended periods, where the temperature of the molten aluminum can typically reach 700–900°C. The heat radiation generated by this high temperature can easily cause worker fatigue and even harm their health. In addition, simply stirring manually makes it difficult to ensure uniform mixing of the gas and molten aluminum, affecting the consistency of the refining process.

[0003] Therefore, it is necessary to improve upon existing technologies and provide an aluminum refining device that can automatically agitate to better mix the refining agent with the molten aluminum. Utility Model Content

[0023] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0024] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] refer to Figure 1-5 This utility model provides an aluminum liquid refining device, including a refining furnace 1, a movable refining cart 2, a stirring component 4, and a first driving component 5. In this embodiment, "movable" means that, assuming the factory floor plane is the reference plane, the refining cart 2 can move freely within the factory floor plane area to move back and forth between different refining furnaces 1, thus having a wider operating range. A frame 20 is fixedly installed on the refining cart 2, and a guide sliding part 3 is provided on the frame 20. The guide sliding part 3 can drive the stirring component 4 to move towards or away from the refining furnace 1, so that the stirring component 4 extends into or out of the refining furnace 1. The first driving component 5 is connected to the stirring component 4 and can drive the stirring component 4 to rotate relative to the frame 20. Specifically, the working principle of the aluminum liquid refining device provided by this utility model is as follows:

[0027] When aluminum molten refining is required, the worker operates the refining cart 2 (e.g., remotely) to stop it at a specific position in front of the refining furnace 1. Then, the guide sliding part 3 drives the agitator 4 to move towards the refining furnace 1 until the agitator 4 extends into the refining furnace 1. After the agitator 4 is fully extended, the first drive part 5 drives the agitator 4 to rotate. During the continuous rotation of the agitator 4, the aluminum molten inside the refining furnace 1 is in a flowing state, thereby continuously refining, degassing, and purifying the aluminum molten. When refining is completed, the first drive part 5 stops working, causing the agitator 4 to stop rotating. At this time, the guide sliding part 3 drives the agitator 4 to move away from the refining furnace 1 until the agitator 4 extends out of the furnace.

[0028] Compared with the existing technology, the aluminum liquid refining device provided by this utility model adopts automated operation throughout the entire process. The only thing the worker needs to do is operate the refining car 2, without the need for manual stirring. This improves the working environment for workers and reduces the risk of heat radiation. At the same time, automated operation also greatly improves processing efficiency and ensures processing quality.

[0029] refer to Figure 2-4 In a preferred embodiment, the guide sliding part 3 includes a guide slide rail 30 and a movable seat 31. The guide slide rail 30 is fixedly mounted on the frame 20 and extends along the axial direction of the frame 20. The movable seat 31 is slidably connected to the guide slide rail 30. In this embodiment, two guide slide rails 30 are provided, which are arranged relatively at intervals on the frame 20. The guide slide rail 30 is provided with a groove. The movable seat 31 is provided with a guide pulley that cooperates with the groove. The guide pulley can roll in the groove, thereby realizing the state of the movable seat 31 sliding along the guide slide rail 30. One end of the stirring element 4 is installed in the movable seat 31 through a bearing 32. The other end of the stirring element 4 extends outward relative to the movable seat 31 (specifically, it extends towards the refining furnace 1). When the movable seat 31 moves along the guide slide rail 30, it can drive the stirring element 4 to move closer to or away from the refining furnace 1. Specifically, bearings 32 are installed at both ends of the movable base 31, and the bearings 32 are sleeved on the outside of the stirring element 4, so that the stirring element 4 can rotate relative to the movable base 31. That is to say, when the first driving element 5 drives the stirring element 4 to rotate, the movable base 31 itself does not rotate. Furthermore, end caps 33 are sealed at both ends of the bearings 32 to prevent external debris from entering the bearings 32 and causing the bearings 32 to jam or be damaged. The end caps 33 mainly serve to protect the bearings 32.

[0030] refer to Figure 2-4 In a preferred embodiment, a second driving component 6 is further included. The second driving component 6 includes a second driving source 60 (also referred to as a second power source, such as a motor) and a transmission part. The transmission part is connected to the movable seat 31. The second driving source 60 is fixed to one end of the guide rail 30. The second driving source 60 can drive the movable seat 31 to slide along the guide rail 30 through the transmission part. The power of the second driving source 60 is transmitted to the movable seat 31 through the transmission part, thereby achieving the effect of automatic movement of the movable seat 31 and further improving the automation of processing and production.

[0031] refer to Figure 2-4In a further preferred embodiment, the transmission unit includes a main sprocket 610 and a driven sprocket 611, which are respectively fixed at both ends of the guide rail 30. The output end of the second drive source 60 is connected to the main sprocket 610, and the main sprocket 610 and the driven sprocket 611 are driven by a transmission chain. The transmission chain is also connected to the movable seat 31. The second drive source 60 can drive the movable seat 31 to move along the guide rail 30 through the transmission chain, so that the stirring element 4 extends into or out of the refining furnace 1. In this embodiment, one end of the transmission chain is fixed to the front end of the movable seat 31 and is sequentially wrapped (sleeved) around the two sprockets. Finally, the other end is fixed to the rear end of the movable seat 31. When the second power source works, it drives the main sprocket 610 to rotate, thereby driving the transmission chain to rotate. Finally, the power is transmitted to the driven sprocket 611 and the movable seat 31 through the transmission chain, so that the movable seat 31 can move linearly on the guide rail 30 (specifically, slide along the guide rail 30). In another embodiment, the main sprocket, driven sprocket, and transmission chain in the transmission unit can also be replaced by a driving wheel, driven wheel, and transmission belt for transmission, as long as the driving relationship with the moving seat can be achieved.

[0032] refer to Figure 2-4 In a preferred embodiment, the first driving component 5 includes a first driving source 50 (such as a motor), a driving wheel 51, and a driven wheel 52. The first driving source 50 is fixed on the movable base 31, and the output end of the first driving source 50 is connected to the driving wheel 51. The driven wheel 52 is sleeved on the outside of the stirring component 4 and fixed to the stirring component 4. The driving wheel 51 and the driven wheel 52 are driven by a transmission belt 53. The first driving source 50 can drive the stirring component 4 to rotate relative to the movable base 31, thereby completing the action of stirring the aluminum liquid in the furnace by the stirring component 4, replacing the traditional manual stirring method.

[0033] refer to Figure 1-5 In a preferred embodiment, the guide sliding part 3 includes a guide slide rail 30, and the stirring member 4 is slidably connected to the guide slide rail 30. The guide slide rail 30 extends along the length direction of the frame 20, and the end of the guide slide rail 30 near the refining furnace 1 is hinged to the frame 20. The aluminum liquid refining device also includes a third driving member 7, which is fixed to the bottom of the frame 20. The third driving member 7 can drive the guide slide rail 30 to rotate relative to the frame 20 (here, rotation refers to rotation in a vertical plane, such as...). Figure 5The rotation direction indicated by the middle arrow (shown in the diagram as the second state of the guide sliding part 3, i.e., the lifted state) causes the stirring angle of the agitator 4 to tilt, allowing it to extend into the furnace bottom for better stirring. In this embodiment, the third driving component 7 specifically includes a third driving source 71 (e.g., a cylinder / electric cylinder), a rotating seat 72, and an ear seat 73. The rotating seat 72 is fixed to the frame 20. One end of the third driving source 71 (cylinder / electric cylinder) is fixed to the rotating seat 72, and the other end (output end) is fixed to the guide rail 30 via the ear seat 73. When the cylinder piston rod extends, it generates an upward thrust on the guide rail 30, thereby lifting the guide rail 30 upward and changing the tilt angle of the guide rail 30 relative to the frame 20. This also changes the tilt angle of the agitator 4 extending into the furnace, allowing the agitator 4 to better stir the molten aluminum. After the stirring operation is completed, the cylinder piston rod retracts, generating a pulling force on the guide rail 30, causing the guide rail 30 to return to its original state. The entire process is automated and controlled. The tilt angle of the stirring component 4 can be adjusted by adjusting the stroke of the cylinder, which further ensures the refining quality of the aluminum liquid.

[0034] refer to Figure 3 In a preferred embodiment, the stirring component 4 includes a stirring shaft 40 and a stirring head 41. The stirring head 41 is fixed to the end of the stirring shaft 40 (the end refers to the end closer to the refining furnace 1 in the working state). A gas channel 401 is formed inside the stirring shaft 40 (this gas channel 401 can be used for both inert gas and refining agent transportation). The gas channel 401 extends through the stirring shaft 40 along its axial direction. The first driving component 5 is connected to the stirring shaft 40. A gas pipe connector 42 is connected to the beginning of the stirring shaft 40 (i.e., the end away from the refining furnace 1). The gas pipe connector 42 has an inlet channel communicating with the gas channel 401. The gas pipe connector 42 is used to connect an external gas source to the gas channel 401 of the stirring shaft 40, thereby transporting inert gas or refining agent into the refining furnace 1 during the refining process.

[0035] In a further preferred embodiment, the air pipe connector 42 is detachably connected to the stirring shaft 40. Specifically, the air pipe connector 42 and the stirring shaft 40 can be connected by threads, so that the air pipe connector 42 can be disassembled and replaced in a timely manner when it is damaged.

[0036] In a preferred embodiment, the gas pipe connector 42 includes a rotating end (not shown) and a fixed end (not shown). The rotating end can rotate relative to the fixed end and is connected between the stirring shaft 40 and the fixed end. The rotating end can rotate synchronously with the stirring shaft 40. Specifically, in this embodiment, the rotating end and the fixed end can be fixed together by a bearing 32 to enable the rotating end to rotate relative to the fixed end. The rotating end is installed to the stirring shaft 40 by a thread, and the fixed end can be used to connect an external hose. During operation, the rotating end can rotate together with the stirring shaft 40, while the fixed end remains stationary. This allows the mixture of inert gas and refining agent to be delivered to the gas channel 401 of the stirring shaft 40 through the gas pipe connector 42, and finally sprayed out from the end of the stirring shaft 40. Simultaneously, it is dispersed by the stirring head 41 during the rotation process, thereby achieving a more uniform refining effect for the molten aluminum.

[0037] refer to Figure 1-5 In a preferred embodiment, a heat insulation plate 21 is provided at one end of the refining cart 2 near the refining furnace 1. One end of the heat insulation plate 21 is connected to the refining cart 2, and the other end extends upward relative to the refining cart 2. An opening 210 is provided on the heat insulation plate 21, which extends through the thickness direction of the heat insulation plate 21. At least a portion of the stirring component 4 can extend out of the opening 210. Since the temperature of the refining furnace 1 is high during operation, the heat insulation plate 21 can isolate a portion of the heat, preventing the equipment from being damaged by heat and resulting in losses.
