Description

Technical Field

[0001] This application relates to the technical field of aluminum alloy degassing equipment, and in particular to a degassing device for aluminum alloy refining and its application process. Background Technology

[0002] Aluminum alloys are alloys based on aluminum, formed by adding other metallic elements to aluminum. The addition of these other metals gives aluminum alloys excellent properties, making them widely used in aerospace, aviation, transportation, construction, and other fields.

[0003] Before aluminum alloys are melted and refined, they need to be degassed. This process removes gases such as hydrogen that can react with aluminum and increases the density of the molten aluminum. The conventional degaussing method involves pouring the molten aluminum into a vacuum chamber and drawing a vacuum to allow the gases to escape. However, vacuum chambers have a slow pumping speed, and the pressure decreases during the pumping process, causing the molten aluminum to easily turn into a gaseous state. Maintaining the molten aluminum in a liquefied state during the pumping process results in low efficiency and high energy consumption. Summary of the Invention

[0013] By adopting the above technical solution, the elastic element connects the first locking block and the second locking block, and can drive the first locking block to move when the second locking block moves.

[0014] Optionally, it also includes a third rotating disk, which has a third vortex groove, and the second snap-fit ​​block snaps into the third vortex groove.

[0015] By adopting the above technical solution, the second snap-fit ​​block is snapped into the third vortex groove, so that the second snap-fit ​​block can rotate in the third vortex groove.

[0016] Optionally, a first through groove and a second through groove are formed on the first rotating disk, the first through groove and the second through groove are connected to the first vortex groove, and a third through groove and a fourth through groove are formed at the bottom of the second rotating disk, the third through groove and the fourth through groove are connected to the second vortex groove, the first through groove corresponds to the third through groove, and the second through groove corresponds to the fourth through groove.

[0017] By adopting the above technical solution, the first locking block can move vertically from the first through slot to the third through slot under elastic action, and the first locking block can move at different heights.

[0018] Optionally, it also includes a support frame that connects the first rotating disk, the second rotating disk, and the third rotating disk.

[0019] By adopting the above technical solution, the support frame is fixedly connected to the first rotating disk, the second rotating disk, and the third rotating disk, so that the height difference between the first rotating disk and the second rotating disk adapts to the height difference in the aluminum liquid tank.

[0020] Optionally, it also includes a rotating component and a telescopic rod. The rotating component is rotatably connected to the support frame. A fifth through slot is opened laterally in the third rotating disk. The telescopic rod is accommodated in the fifth through slot and connects the rotating component to the second locking block.

[0021] By adopting the above technical solution, the telescopic rod connects the rotating component and the second locking block, so that when the rotating component rotates, it can drive the telescopic rod to extend and retract, thereby moving the electric second locking block within the third rotating disk.

[0022] Optionally, it also includes a reset component, which is fixed on the support frame. The rotating component includes a rotating rod and a gear. The rotating rod is fixedly connected to the telescopic rod and rotatably connected to the support frame. The rotating rod is fixedly connected to the gear and the gear meshes with the reset component.

[0023] By adopting the above technical solution, the gear meshes with the reset component, which enables the rotating rod to rotate when it rotates, and the reset component to drive the rotating rod to rotate in the opposite direction and return it to its original position when it does not rotate.

[0024] Secondly, the application process of a degassing equipment for aluminum alloy refining provided in this application adopts the following technical solution: A degassing equipment application process for aluminum alloy refining includes the following steps: S1: Before using the degassing equipment, nitrogen gas is introduced to remove debris from the degassing pipe to ensure that there is no blockage in the degassing pipe; S2: After preheating the degassing pipe, slowly push the preheated degassing pipe into the molten aluminum. The powder outlet at the very front of the degassing pipe needs to be immersed in the molten aluminum to a certain depth but cannot completely contact the bottom of the furnace to avoid clogging of the degassing pipe. S3: Open the pressure valve to allow the refining agent and nitrogen to be introduced into the molten aluminum together; S4: During the degassing process, move the degassing vehicle back and forth to ensure that the powder outlet can cover the entire aluminum liquid area during operation. S5: After degassing is completed, move the degassing cart away from the molten aluminum. After the degassing pipe leaves the molten aluminum, gently shake the degassing cart and tap the degassing pipe to blow out the residue inside the degassing pipe.

[0025] By adopting the above technical solution, the problems of slow vacuum pumping speed, easy gasification of molten aluminum due to pressure reduction during pumping, low efficiency and high energy consumption caused by the need to maintain the liquefied state of molten aluminum during pumping are solved by introducing nitrogen and refining agent into the molten aluminum.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Slowly push the preheated degassing pipe into the molten aluminum, open the pressure valve, and let the refining agent and nitrogen gas be introduced into the molten aluminum together. The refining agent removes hydrogen and floating oxide impurities from the molten aluminum, while the nitrogen gas does not react with the molten aluminum and can squeeze out the air in the molten aluminum.

[0027] By introducing nitrogen and refining agents into the molten aluminum, the problems of slow vacuum pumping speed, the tendency of molten aluminum to turn into a gaseous state due to pressure reduction during pumping, and the need to maintain the liquefied state of the molten aluminum during pumping are solved, resulting in low efficiency and high energy consumption.

[0028] 2. Move the support frame to a suitable position. The second locking block in the third vortex groove is connected to the first locking block in the first vortex groove through the first spring. The first locking block is connected to the degassing pipe. Rotate the rotating rod clockwise, and the gear drives the rack to move, stretching the second spring. The second locking block in the third vortex groove is connected to the rotating rod through the telescopic rod. Rotating the rotating rod clockwise causes the telescopic rod to retract, and the second locking block moves inward toward the center. The first locking block, connected to the first locking block through the first spring, moves inward from the outer circumference of the first vortex groove. At this time, the powder outlet of the degassing pipe makes a vortex motion in the middle and lower part of the aluminum liquid tank. The first locking block moves to the first through groove at the center. Under the elastic action of the first spring, the first locking block moves to the third through groove of the second vortex groove. At this point, the rotating rod is released, and under the elastic action of the second spring, the rack moves towards the fixed seat, causing the rotating rod to rotate counterclockwise. The telescopic rod extends, and the second locking block moves towards the outer circumference, causing the first locking block to move towards the outer circumference within the second vortex groove. At this time, the powder outlet of the degassing pipe makes a vortex motion in the upper middle part of the aluminum liquid tank.

[0029] The degassing pipe can first make a vortex motion in the lower middle part of the aluminum liquid tank, and then move to the upper middle part of the aluminum liquid tank to make a vortex motion. The refining agent and nitrogen discharged from the degassing pipe can cover the entire aluminum liquid area, thus improving the degassing efficiency of the aluminum liquid.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0032] This application discloses a degassing device for aluminum alloy refining and its application process.

[0033] Example 1 Reference Figure 1A degassing device for aluminum alloy refining includes a degassing cart 10, a powder discharger 20, a degassing pipe 30, a support frame 40, a first rotating disk 50, a second rotating disk 60, a third rotating disk 70, a rotating component 80, a telescopic rod 90, a second locking block 100, a connecting pipe 110, an elastic component 120, a first locking block 130, and a reset component 140. The powder discharger 20 is mounted on the degassing cart 10. One end of the degassing pipe 30 is connected to the powder discharger 20, and the other end is connected to the molten aluminum. The powder discharger 20 provides nitrogen and a refining agent. The refining agent is a white powdery or granular solvent that removes hydrogen and suspended oxide impurities from the molten aluminum. The preheated degassing pipe 30 is slowly pushed into the molten aluminum, and the pressure valve is opened, allowing the refining agent and nitrogen to be introduced into the molten aluminum together. The refining agent removes hydrogen and suspended oxide impurities from the molten aluminum, while the nitrogen does not react with the molten aluminum and can expel air from the molten aluminum. By introducing nitrogen and refining agents into the molten aluminum, the problems of slow vacuum pumping speed, the tendency of molten aluminum to turn into a gaseous state due to pressure reduction during pumping, and the need to maintain the liquefied state of the molten aluminum during pumping are solved, resulting in low efficiency and high energy consumption.

[0034] Reference Figure 2 and Figure 3 The first rotating disk 50, the second rotating disk 60 and the third rotating disk 70 are fixedly connected to the support frame 40. The rotating component 80 is rotatably connected to the support frame 40. The telescopic rod 90 is fixedly connected to the rotating component 80. The third rotating disk 70 is provided with a third vortex groove 71. The second locking block 100 can move in the third vortex groove 71. The other end of the telescopic rod 90 is connected to the second locking block 100.

[0035] The rotating component 80 is rotatably connected to the support frame 40. When the rotating component 80 rotates, it drives the telescopic rod 90 to extend and retract. The telescopic rod 90 has multiple sections. The second locking block 100 at the other end of the telescopic rod 90 moves within the third vortex groove 71. When the rotating component 80 rotates clockwise, the telescopic rod 90 retracts inward, and the second locking block 100 rotates along the third vortex groove 71 toward the center of the third rotating disk 70. When the rotating component 80 rotates counterclockwise, the telescopic rod 90 extends outward, and the second locking block 100 rotates along the third vortex groove 71 toward the outer periphery of the third rotating disk 70.

[0036] Reference Figure 1 , Figure 2 and Figure 3The degassing pipe 30 is a relatively long flexible tube, and the connecting pipe 110 is a rotatable pipe that can change direction. The connecting pipe 110 is connected to the degassing pipe 30, and a valve 111 is provided at the connection point between the connecting pipe 110 and the degassing pipe 30. The first rotating disk 50 is located below the second rotating disk 60. The first rotating disk 50 is provided with a first vortex groove 51, and the first locking block 130 can move within the first vortex groove 51. The second rotating disk 60 is provided with a second vortex groove 61, and the first locking block 130 can move within the second vortex groove 61. The side of the first locking block 130 is provided with an annular groove 131, which is a T-shaped groove. The connecting pipe 110 is slidably connected within the annular groove 131.

[0037] The first clamping block 130 is cylindrical. Valve 111 is normally closed. The powder discharger 20 provides nitrogen and refining agent, which are introduced into the molten aluminum. The first clamping block 130 is connected to the degassing pipe 30. The movement of the first clamping block 130 can drive the powder outlet of the degassing pipe 30, which vents into the molten aluminum, to move within the molten aluminum. When the first clamping block 130 moves within the first vortex 51, the powder outlet rotates in the lower part of the molten aluminum tank 150; when the first clamping block 130 moves within the second vortex 61, the powder outlet rotates in the upper part of the molten aluminum tank 150.

[0038] The first vortex 51 and the second vortex 61 can be set to multiple. In this case, the powder outlet can rotate at different positions in the depth direction of the aluminum liquid. The powder outlet introduces nitrogen and refining agent into various directions of the aluminum liquid. The powder outlet covers the entire aluminum liquid area. Air in the aluminum liquid at all positions of the aluminum liquid tank 150 is discharged, improving the degassing efficiency.

[0039] Reference Figure 2 and Figure 3 The elastic element 120 connects the first snap-fit ​​block 130 and the second snap-fit ​​block 100.

[0040] The elastic element 120 can be the first spring 121. When the second locking block 100 rotates towards the center or the outer periphery in the third vortex groove 71, the first locking block 130, which is connected to the second locking block through the first spring 121, can move towards the center or the outer periphery in the first vortex groove 51 or the second vortex groove 61. Thus, the movement of the second locking block 100 in the third vortex groove 71 can drive the movement of the first locking block 130, thereby driving the movement of the powder outlet in the aluminum liquid tank 150.

[0041] Reference Figure 4 , Figure 5 and Figure 6 A first through groove 52 is opened on the first rotating disk 50, and the first through groove 52 is opened near the center. A third through groove 62 is opened at the bottom of the second rotating disk 60, and the third through groove 62 is opened near the center. The first through groove 52 and the third through groove 62 correspond to each other in the vertical direction.

[0042] The first locking block 130 rotates towards the center within the first vortex groove 51. At this time, the powder outlet of the degassing pipe 30 vortexes in the lower part of the aluminum liquid tank 150. When the first locking block 130 rotates to the position of the first through groove 52, under the elastic action of the first spring 121, the first locking block 130 moves upward from the first through groove 52 to the third through groove 62. Then, driven by the second locking block 100, the first locking block 130 moves towards the outer circumference within the second vortex groove 61. At this time, the powder outlet of the degassing pipe 30 vortexes in the upper part of the aluminum liquid tank 150.

[0043] At the same time, the first locking block 130 moves from the first rotating disk 50 to the second rotating disk 60, and the powder outlet of the degassing pipe 30 moves from the lower middle part to the upper middle part to prevent the aluminum liquid moving from top to bottom from entering the degassing pipe 30 from the powder outlet, causing blockage or contamination of the degassing pipe 30.

[0044] Reference Figure 4 , Figure 5 and Figure 6 A second through groove 53 is opened on the first rotating disk 50, and the second through groove 53 is opened near the outer circumference of the circle. A fourth through groove 63 is opened at the bottom of the second rotating disk 60, and the fourth through groove 63 is opened near the outer circumference of the circle. The second through groove 53 and the fourth through groove 63 correspond to each other in the vertical direction.

[0045] When the first locking block 130 rotates its outer circumference within the second vortex groove 61, manually pulling the first locking block 130 will move it from the fourth through groove 63 to the third through groove 62, and then into the first vortex groove 51 for easy reuse. A blocking block 54 is provided within the first vortex groove 51. After the first locking block 130 of the degassing device is pulled into the first vortex groove 51, the blocking block 54 will close, preventing the first locking block 130 from entering the third through groove 62.

[0046] Reference Figure 2 and Figure 5 The reset component 140 is fixed on the support frame 40. The rotating component 80 includes a rotating rod 81 and a gear 82. The rotating rod 81 is fixedly connected to the telescopic rod 90 and rotatably connected to the support frame 40. The rotating rod 81 is also fixedly connected to the gear 82, which meshes with the reset component 140. By rotating the rotating rod 81, the gear 82 can be driven to rotate, which in turn drives the reset component 140 fixed on the support frame 40 to move.

[0047] Reference Figure 5The specific structure of the reset component 140 and its specific connection relationship with the gear 82 and the support frame 40 are as follows: The reset component 140 includes a fixed seat 141, a second spring 142, a rack 143 and a protrusion 144. The fixed seat 141 is fixedly mounted on the bottom of the support frame 40. A groove 41 is opened on the support frame 40. The groove 41 is a T-shaped groove. The protrusion 144 is engaged in the groove 41 and slidably connected. The protrusion 144 is fixedly mounted on the rack 143. The second spring 142 connects the fixed seat 141 and the rack 143. The rack 143 meshes with the gear 82.

[0048] When the first locking block 130 is manually rotated clockwise around the outer circumference of the first vortex groove 51, the gear 82 rotates and drives the rack 143 to move away from the fixed seat 141, stretching the second spring 142. At the same time, the powder outlet of the degassing pipe 30 performs a vortex motion in the lower middle part of the aluminum liquid tank 150. When the rotating rod 81 rotates clockwise to the point where the first locking block 130 springs from the first through groove 52 to the third through groove 62 of the second vortex groove 61, the rotating rod 81 is released. Under the elastic action of the second spring 142, the rack 143 moves towards the fixed seat 141, and the gear 82 and rack 143 mesh. The gear 82 drives the rotating rod 81 to rotate counterclockwise. At this time, the first locking block 130 moves counterclockwise around the outer circumference of the second vortex groove 61, and the powder outlet of the degassing pipe 30 performs a vortex motion in the upper middle part of the aluminum liquid tank 150.

[0049] The implementation principle of the degassing equipment for aluminum alloy refining in this embodiment is as follows: the preheated degassing pipe 30 is slowly pushed into the molten aluminum, the pressure valve is opened, and the refining agent and nitrogen are introduced into the molten aluminum together. The refining agent removes hydrogen and floating oxide impurities from the molten aluminum, while the nitrogen does not react with the molten aluminum and can squeeze out the air in the molten aluminum.

[0050] Move the support frame 40 to a suitable position. The second locking block 100 in the third vortex groove 71 is connected to the first locking block 130 in the first vortex groove 51 via the first spring 121. The first locking block 130 is connected to the degassing pipe 30. Rotate the rotating rod 81 clockwise, and the gear 82 drives the rack 143 to move, stretching the second spring 142. The second locking block 100 in the third vortex groove 71 is connected to the rotating rod 81 via the telescopic rod 90. Rotating the rotating rod 81 clockwise drives the rack 143 to move. The telescopic rod 90 retracts, and the second locking block 100 moves inward towards the center. The first locking block 130, connected to the second locking block 100 via the first spring 121, moves inward from the outer circumference of the first vortex groove 51. At this time, the powder outlet of the degassing pipe 30 vortexes in the lower middle part of the aluminum liquid tank 150. The first locking block 130 moves to the first through groove 52 at the center, and then moves to the third through groove 62 of the second vortex groove 61 under the elastic action of the first spring 121. At this time, the rotating rod 81 is released. Under the elastic action of the second spring 142, the rack 143 moves towards the fixed seat 141, causing the rotating rod 81 to rotate counterclockwise. The telescopic rod 90 extends, and the second locking block 100 moves outward towards the outer circumference, causing the first locking block 130 to move outward within the second vortex groove 61. At this time, the powder outlet of the degassing pipe 30 vortexes in the upper middle part of the aluminum liquid tank 150.

[0051] The degassing pipe 30 can first make a vortex motion in the lower middle part of the aluminum liquid tank 150, and then move to the upper middle part of the aluminum liquid tank 150 to make a vortex motion. The refining agent and nitrogen discharged from the degassing pipe 30 can cover the entire aluminum liquid area, thus improving the degassing efficiency of the aluminum liquid.

[0052] Example 2 Reference Figure 1 An application process for degassing equipment in aluminum alloy refining, the difference between this embodiment and Embodiment 1 is that it includes the following steps: S1: Before using the degassing equipment, introduce nitrogen to remove debris from the degassing pipe 30 to ensure that there is no blockage in the degassing pipe 30. S2: After preheating the degassing pipe 30, slowly push the preheated degassing pipe 30 into the aluminum liquid. The powder outlet at the front end of the degassing pipe 30 needs to be immersed in the aluminum liquid to a certain depth but cannot completely contact the bottom of the furnace to avoid clogging of the degassing pipe 30. S3: Open the pressure valve to allow the refining agent and nitrogen to be introduced into the molten aluminum together; S4: During the degassing process, the degassing vehicle 10 moves back and forth to ensure that the powder outlet can cover the entire aluminum liquid area during operation. S5: After degassing is completed, move the degassing cart 10 away from the molten aluminum. After the degassing pipe 30 leaves the molten aluminum, gently shake the degassing cart 10 and tap the degassing pipe 30 to blow out the residue inside the degassing pipe 30.
