Description

Technical Field

[0001] This application relates to the field of building material solid waste utilization technology, specifically to an aluminum alloy melt degassing device. Background Technology

[0002] Aluminum alloys are a widely used structural material in the construction industry, and their usage is undeniably vast. However, the material's susceptibility to corrosion and its fragility leads to the generation of a large amount of waste aluminum alloy building materials. If these waste materials are discarded indiscriminately, they will not only cause serious environmental pollution but also waste valuable aluminum alloy resources. Therefore, the crushing and recycling of these waste aluminum alloy building materials is particularly important. Currently, the common practice is to use a crusher to shred the waste aluminum alloy building materials into small pieces, and then melt these pieces to increase their recycling value.

[0003] However, the presence of bubbles in molten aluminum alloys is a problem that cannot be ignored. These bubbles form cavities during the solidification process of the aluminum alloy, thereby reducing the structural strength of the final product. Therefore, how to effectively reduce the bubble content in molten aluminum alloys has become a key technical challenge that urgently needs to be solved in this field. Utility Model Content

[0004] In view of this, this application provides a degassing device for molten aluminum alloy, which can effectively reduce the bubble content in molten aluminum alloy.

[0005] In a first aspect, this application provides a degassing device for molten aluminum alloy, comprising: a molten aluminum alloy receiving ring for receiving molten aluminum alloy output from an outlet, the molten aluminum alloy receiving ring including an annular liquid tank; an outlet pipe connected to the side of the molten aluminum alloy receiving ring, the length direction of the outlet pipe passing through the center of the molten aluminum alloy receiving ring, the lumen of the outlet pipe communicating with the liquid tank, the number of outlet pipes being multiple, the multiple outlet pipes being evenly arranged around the outer periphery of the molten aluminum alloy receiving ring; a receiving ring surrounding the spray direction of the multiple outlet pipes, the receiving ring having a receiving groove facing the outlet of the outlet pipe, the bottom of the receiving ring having a drain nozzle; a storage tank, the drain nozzle extending into the storage tank; and a rotation driver disposed within the molten aluminum alloy receiving ring, the rotation driver being connected to the molten aluminum alloy receiving ring to drive the molten aluminum alloy receiving ring to rotate.

[0006] In conjunction with the first aspect, in one possible implementation, the outlet is located above the rotation trajectory of the liquid tank.

[0007] In conjunction with the first aspect, in one possible implementation, the horizontal height of the lower edge of the cavity where it connects with the liquid tank is higher than the horizontal height of the bottom plate of the liquid tank.

[0008] In conjunction with the first aspect, in one possible implementation, the liquid receiving ring includes a liquid inlet located in the liquid outlet direction of the liquid outlet pipe.

[0009] In conjunction with the first aspect, in one possible implementation, the number of drain nozzles is multiple, and the multiple drain nozzles are evenly arranged along the circumferential direction of the liquid receiving ring.

[0010] In conjunction with the first aspect, in one possible implementation, the drain nozzle is an arc-shaped tube that extends toward the side wall of the storage tank.

[0011] In conjunction with the first aspect, in one possible implementation, the arc direction of the drain nozzle is upward convex.

[0012] In conjunction with the first aspect, in one possible implementation, the rotary actuator includes a rotary drive disk, which is interconnected with the molten metal receiving ring via connecting spokes.

[0013] In conjunction with the first aspect, in one possible implementation, the number of connecting spokes is multiple, and the multiple connecting spokes are evenly distributed between the rotating drive disk and the molten metal receiving ring.

[0014] In conjunction with the first aspect, in one possible implementation, the liquid storage tank is cylindrical, and the liquid receiving ring is located above the tank body of the liquid storage tank.

[0015] In application, the rotary driver rotates the molten aluminum receiving ring, while the outlet position remains fixed. Molten aluminum alloy exits from the outlet and falls into the liquid tank of the molten aluminum receiving ring. During continuous rotation, the molten aluminum receiving ring eliminates some air bubbles. Simultaneously, under centrifugal force, the molten aluminum alloy enters the cavity of the outlet pipe, which is rotated by the molten aluminum receiving ring. Under centrifugal force, the molten aluminum alloy is ejected from the cavity of the outlet pipe and falls into the liquid receiving tank of the receiving ring. Centrifugal force causes the molten aluminum alloy to collide with the liquid receiving tank, further eliminating air bubbles. The liquid receiving tank then discharges the collected molten aluminum alloy into the storage tank through the drain nozzle. This application can eliminate air bubbles in molten aluminum alloy by rotating the continuously moving molten aluminum receiving ring and using centrifugal force. Attached Figure Description

[0026] Aluminum alloys are a widely used structural material in the construction industry, and their usage is undeniably vast. However, the material's susceptibility to corrosion and its fragility leads to the generation of a large amount of waste aluminum alloy building materials. If these waste materials are discarded indiscriminately, they will not only cause serious environmental pollution but also waste valuable aluminum alloy resources. Therefore, the crushing and recycling of these waste aluminum alloy building materials is particularly important. Currently, the common practice is to use a crusher to shred the waste aluminum alloy building materials into small pieces, and then melt these pieces to increase their recycling value.

[0027] However, the presence of bubbles in molten aluminum alloys is a problem that cannot be ignored. These bubbles form cavities during the solidification process of the aluminum alloy, thereby reducing the structural strength of the final product. Therefore, how to effectively reduce the bubble content in molten aluminum alloys has become a key technical challenge that urgently needs to be solved in this field.

[0028] In view of this, this application provides a degassing device for molten aluminum alloy, which can effectively reduce the bubble content in molten aluminum alloy.

[0029] An exemplary aluminum alloy molten metal degassing device is as follows:

[0030] Figure 1 The diagram shown is a top view of an aluminum alloy melt degassing device according to an embodiment of this application. Figure 2The image shown is a partial side cross-sectional view of an aluminum alloy molten metal degassing device according to another embodiment of this application. This application provides an aluminum alloy molten metal degassing device; in one embodiment, as shown... Figure 1 As shown, the aluminum alloy molten metal degassing device includes: a molten metal receiving ring 2, an outlet pipe 3, a receiving ring 4, a storage tank 5, and a rotary driver 6. The molten metal receiving ring 2 receives the molten aluminum alloy output from the outlet 1 and includes an annular liquid tank 201. The outlet pipe 3 is connected to the side of the molten metal receiving ring 2, and its length passes through the center of the molten metal receiving ring 2. The cavity 301 of the outlet pipe 3 communicates with the liquid tank 201. Multiple outlet pipes 3 are evenly arranged around the outer periphery of the molten metal receiving ring 2. The receiving ring 4 surrounds the multiple outlet pipes 3 in the spray direction. The receiving ring 4 has a receiving groove 401 facing the outlet of the outlet pipe 3, and a drain nozzle 402 at the bottom of the receiving ring 4. The drain nozzle 402 extends into the storage tank 5. The rotary actuator 6 is disposed inside the molten metal receiving ring 2, and the rotary actuator 6 is connected to the molten metal receiving ring 2 to drive the molten metal receiving ring 2 to rotate.

[0031] In this embodiment, the rotating driver 6 drives the molten alloy receiving ring 2 to rotate, while the position of the outlet 1 remains fixed. Molten aluminum alloy is output from the outlet 1 and falls into the liquid tank 201 of the molten alloy receiving ring 2. During the continuous rotation of the molten alloy receiving ring 2, some air bubbles in the molten aluminum alloy are eliminated. Simultaneously, under centrifugal force, the molten aluminum alloy enters the cavity 301 of the outlet pipe 3. The outlet pipe 3 is rotated along with the molten alloy receiving ring 2. Under centrifugal force, the molten aluminum alloy is ejected from the cavity 301 of the outlet pipe 3 and falls into the receiving tank 401 of the receiving ring 4. Centrifugal force causes the molten aluminum alloy to collide with the receiving tank 401, further eliminating air bubbles in the molten aluminum alloy. The receiving tank 401 then discharges the received molten aluminum alloy into the storage tank 5 through the drain nozzle 402. This embodiment can eliminate air bubbles in the molten aluminum alloy by rotating the continuously moving molten alloy receiving ring 2 and using centrifugal force.

[0032] Specifically, such as Figure 2 As shown, the liquid outlet 1 is located above the rotation trajectory of the liquid tank 201.

[0033] In one embodiment, such as Figure 2 As shown, the lower edge of the cavity 301 where it connects with the liquid tank 201 is at a higher level than the bottom plate of the liquid tank 201, allowing the liquid tank 201 to store a certain amount of molten aluminum alloy. When the molten aluminum alloy receiving ring 2 rotates, the relative movement between the bottom of the liquid tank 201 and the molten aluminum alloy eliminates some air bubbles. Once the molten aluminum alloy stored in the liquid tank 201 reaches a certain volume, it flows into the outlet pipe 3 and is discharged through the cavity 301.

[0034] In one embodiment, such as Figure 2As shown, the receiving ring 4 includes an inlet 405, which is located in the outlet direction of the outlet pipe 3. When the molten metal receiving ring 2 drives the outlet pipe 3 to rotate, under the action of centrifugal force, the molten aluminum alloy is sprayed out of the outlet pipe 3 and enters the receiving ring 4 through the inlet 405.

[0035] In one embodiment, there are multiple drain nozzles 402, which are evenly arranged along the annular direction of the receiving ring 4, so that the molten aluminum alloy in the receiving ring 4 can be discharged into the storage tank 5 through the multiple drain nozzles 402.

[0036] In one embodiment, such as Figure 2 As shown, the drain nozzle 402 is an arc-shaped tube that extends toward the side wall of the liquid storage tank 5. The arc-shaped drain nozzle 402 allows the molten aluminum alloy to gradually slide down along the arc-shaped tube wall, avoiding excessive flow rate that could lead to the formation of new bubbles.

[0037] In one embodiment, such as Figure 2 As shown, the arc of the drain nozzle 402 is convex upward, which can better buffer the discharge process of molten aluminum alloy in the drain nozzle 402.

[0038] In one specific embodiment, the bottom end of the drain nozzle 402 is at a distance of 5cm to 10cm from the side wall of the storage tank 5, thereby reducing the mutual impact between the molten aluminum alloy and the side wall of the storage tank 5 and thus reducing the generation of bubbles, so that the molten aluminum alloy can flow down along the side wall.

[0039] In one embodiment, such as Figure 1 As shown, the rotary actuator 6 includes a rotary drive disk, which is connected to the molten metal receiving ring 2 via connecting spokes 601, thereby driving the molten metal receiving ring 2 to rotate via the connecting spokes 601.

[0040] In one embodiment, such as Figure 1 As shown, there are multiple connecting spokes 601, which are evenly distributed between the rotating drive disk and the molten metal receiving ring 2.

[0041] Specifically, the liquid storage tank 5 is cylindrical, and the liquid receiving ring 4 is located above the tank body of the liquid storage tank 5 to ensure that the molten aluminum alloy in the liquid receiving ring 4 can fall into the liquid storage tank 5.
