Description

[0002] Liquid aluminum filtration and degassing equipment is a crucial tool in the aluminum casting process, significantly improving the quality and performance of aluminum castings. Liquid aluminum refining degassing and deslagging machines are a type of liquid aluminum filtration and degassing equipment. This equipment plays a key role in the liquid aluminum processing process, primarily removing gases, inclusions, and solid slag from the liquid aluminum.

[0003] During the operation of a degassing and deslagging machine for molten aluminum refining, impurities in the molten aluminum float up. However, conventional degassing and deslagging machines often lack a slag removal mechanism, requiring workers to manually remove the slag using a shovel.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] See Figure 1-2 The aluminum refining, degassing, and deslagging machine body 1 is equipped with a vertical drive assembly, which consists of a slide rail and a vertical screw. The refining, degassing, and deslagging assembly 11 is driven and moved by the vertical screw. A graphite rotor 12 is mounted on the refining, degassing, and deslagging assembly 11, which is rotated by a main shaft. The graphite rotor 12 is fed into the aluminum liquid pool 13. The rotating graphite rotor 12 blows an inert gas (such as argon or nitrogen) into the aluminum liquid and breaks it into a large number of dispersed bubbles. These bubbles absorb hydrogen from the aluminum liquid and adsorb oxidized slag inclusions through the gas partial pressure difference and surface adsorption principles. They are then carried to the surface of the aluminum liquid as they float, thereby achieving the refining, degassing, and deslagging of the aluminum liquid. It is worth noting that the specific structures for processing the aluminum liquid in the aluminum refining, degassing, and deslagging machine body 1, the refining, degassing, and deslagging assembly 11, and the graphite rotor 12 are all prior art and are therefore not described in detail in this disclosure.

[0044] See Figure 3-5 A lower fixed plate 2 is fixedly provided on the outside of the refining, degassing and slag removal assembly 11. First guide columns 21 are fixedly provided vertically upward on both sides of the top of the lower fixed plate 2, and the other ends of the first guide columns 21 are connected to the upper fixed plate 22. A screw rod 24 is rotatably provided between the lower fixed plate 2 and the upper fixed plate 22, and the screw rod 24 is driven to rotate by the drive motor 23 on the top of the upper fixed plate 22. The movable plate 25 is guided and moved by the first guide column 21, and a threaded cavity is adapted to be opened on the movable plate 25 corresponding to the screw rod 24, which allows the movable plate 25 to move vertically through the rotation of the screw rod 24, thereby driving the slag scooping piece 3 on the movable plate 25 to move synchronously.

[0045] A guide block 26 is fixedly mounted on the refining, degassing and slag removal assembly 11. A guide cavity 251 is adapted to fit the guide block 26 on the movable plate 25. A second guide post 252 is fixedly mounted within the guide cavity 251, and the second guide post 252 passes through the guide block 26. The guide block 26 further guides the movable plate 25, thereby improving its stability during movement.

[0046] A fixed pressure column 27 is fixed downwardly provided at the bottom of the refining, degassing and deslagging assembly 11 , and the fixed pressure column 27 is aligned with the pressure piece 72 .

[0047] A plurality of mounting rods 253 are fixed to the ends of the movable plate 25. Each of these rods has screw holes, allowing the slag scoop 3 to be fixed to the rods 253 with screws. It is also worth noting that the slag scoop 3 is available in a variety of sizes, and the sizes of the fixed bin 4, fixed column 5, bottom bin 6, and crossbar 7 all vary to match the slag scoop 3. Users can install the appropriate slag scoop 3 on the movable plate 25 according to the size of the molten aluminum tank 13.

[0048] See Figure 6-9 The slag removal unit 3 is fixedly mounted with a molten aluminum filter 31, which filters impurities from the molten aluminum. Multiple third guide posts 33 are also fixedly mounted on the slag removal unit 3, guiding the push plate 32. The push plate 32 is movable to remove impurities accumulated on the molten aluminum filter 31. It is worth noting that the molten aluminum filter 31 is made of a high-temperature resistant material such as fiberglass or ceramic foam, allowing it to filter impurities even in high-temperature molten aluminum.

[0049] Fixed bins 4 are fixed on both sides of the top of the slag scooping piece 3 through support columns, and movable cavities 41 are opened inside the fixed bins 4. Fourth guide columns 44 are fixed in the movable cavities 41, and movable parts 42 are arranged in the movable cavities 41 to be guided by the fourth guide columns 44.

[0050] A first spring 43 is mounted on one side of the movable chamber 41. The other end of each first spring 43 is connected to the movable member 42, and each first spring 43 is located outside the fourth guide post 44. A traction rope 46 is fixedly connected to the other side of the movable member 42, and the other end of each traction rope 46 extends from the end of the fixed chamber 4. It is worth noting that the traction rope 46 is made of a high-temperature resistant material such as glass fiber or ceramic fiber to ensure normal operation in high-temperature environments.

[0051] The bottom of the movable member 42 is fixedly provided with a connecting member 421, and the connecting member 421 passes through the connecting cavity 45 and is fixedly connected to the push plate 32. By setting the connecting member 421 on the movable member 42 on both sides, the push plate 32 can move synchronously with the connecting member 421.

[0052] See Figure 6 、 10-11, the top of the movable part 42 is provided with a card cavity 422 downwardly, and a wedge-shaped card 424 is movably provided in the card cavity 422. The bottom of the card cavity 422 is installed with an upward extension spring 423, and the other end of the extension spring 423 is connected to the bottom of the wedge-shaped card 424. Through the provision of the extension spring 423, the wedge-shaped card 424 can be automatically pushed upward and reset by the extension spring 423 after being pressed into the card cavity 422. It is also worth noting that a guide plate is fixedly provided on the wedge-shaped card 424, and a guide groove is adapted to be provided on the corresponding guide plate in the card cavity 422. Through the adaptation between the guide plate and the guide groove, not only can the guided movement of the wedge-shaped card 424 be achieved, but also the wedge-shaped card 424 can be prevented from falling out of the card cavity 422.

[0053] When the movable member 42 moves within the movable cavity 41, it can drive the wedge-shaped clamping member 424 to move synchronously. When the movable member 42 moves to the clamping cavity 40, the wedge-shaped clamping member 424 can be automatically pushed upward by the elastic force of the extension spring 423. This can push the wedge-shaped clamping member 424 into the clamping cavity 40, thereby making the wedge-shaped clamping member 424 locked in the clamping cavity 40, thereby fixing the movable member 42 below the clamping cavity 40.

[0054] A fifth guide post 73 is fixedly mounted vertically upward on the top of each fixed compartment 4 on one side of the card cavity 40, and the crossbar 7 is guided by the fifth guide post 73. A second spring 74 is mounted upward on the top of each fixed compartment 4 on the outer side of the fifth guide post 73, and the other end of the second spring 74 is connected to the crossbar 7.

[0055] Both ends of the crossbar 7 are fixed downwardly with pressure pieces 72, which are aligned with the wedge-shaped clamping piece 424. A top plate 71 is fixedly provided on the top of the crossbar 7, and the top plate 71 is aligned with the fixed pressure column 27. This allows the crossbar 7 and the top plate 71 to move upward synchronously when the movable plate 25 moves upward. When the top plate 71 contacts the fixed pressure column 27, the top plate 71 is unable to move further due to the fixed pressure column 27, while the movable plate 25 continues to move upward. Therefore, the fixed pressure column 27 allows the top plate 71 to move downward relative to the movable plate 25. At this time, the crossbar 7, the top plate 71, and the pressure pieces 72 on both sides can all move synchronously into the clamping cavity 40, thereby pressing the wedge-shaped clamping piece 424 into the clamping cavity 422, and the second spring 74 is compressed. This can release the mutual blocking between the wedge-shaped clamping piece 424 and the clamping cavity 40, thereby releasing the fixed limit on the movable member 42. Furthermore, when the movable plate 25 moves downward, the cross bar 7 , the top plate 71 and the pressing pieces 72 on both sides can be automatically reset by the elastic force of the second spring 74 .

[0056] See Figure 6 、12 -16, a fixing column 5 is fixed vertically upward on the top of each fixing chamber 4, and a fixing seat 51 is fixed on the top of each fixing column 5. A guide rope ring 52 and a connecting seat 53 are fixed on both sides of the inner wall of the fixing seat 51. This allows the traction rope 46 extending from the fixing chamber 4 to pass through the guide rope ring 52 and then connect to the connecting seat 53, so that the traction rope 46 is flat between the guide rope ring 52 and the connecting seat 53.

[0057] The bottom bin 6 has a bottom cavity 61 formed inside, within which a movable partition 62 is vertically and movably disposed. A fixing member 63 is fixedly disposed on the top of the movable partition 62, and a top column 621 is fixedly disposed vertically upward from the top of the fixing member 63. The top column 621 extends from the bottom bin 6. A connecting rod 622 is fixedly disposed on the top of the top column 621, and a rope-pressing member 623 is fixedly disposed on the connecting rod 622. The rope-pressing member 623 is located above the traction rope 46. When the rope-pressing member 623 moves downward, it presses the traction rope 46 downward, thereby pulling the traction rope 46, thereby pulling the movable member 42 via the traction rope 46. When the rope-pressing member 623 moves upward, the traction rope 46 automatically resets.

[0058] A plurality of vertical guide members 610 are fixedly provided on the inner wall of the bottom cavity 61, and guide grooves 620 are adapted to be opened on the movable partition 62 corresponding to the guide members 610. The adaptation setting between the guide members 610 and the guide grooves 620 can improve the stability of the movable partition 62 during the activity.

[0059] Upper through cavities 64 are formed on both sides above the bottom cavity 61, lower through cavities 65 are formed on both sides below the bottom cavity 61, and multiple bottom through cavities 66 are formed at the bottom of the bottom cavity 61. This ensures that when the bottom bin 6 is filled with molten aluminum, the air pressure below the movable partition 62 prevents the molten aluminum from entering the bottom cavity 61 from the lower through cavities 65 and the bottom through cavities 66. Therefore, air still remains in the bottom cavity 61 below the movable partition 62.

[0060] The arrangement of the fixing member 63 allows the movable partition 62 to be spaced a certain distance from the top of the bottom chamber 61, thus preventing the movable partition 62 from blocking the upper through chamber 64. This allows molten aluminum to enter the bottom chamber 61 through the upper through chamber 64 and above the movable partition 62. Consequently, the pressure of the molten aluminum above the movable partition 62 pushes the movable partition 62 downward, while the air below the movable partition 62 is discharged through the lower through chamber 65 and the bottom through chamber 66. As a result, the movable partition 62 drives the top column 621, the connecting rod 622, and the rope-pressing member 623 to move downward synchronously.

[0061] When the bottom bin 6 moves upward out of the water, the water in the bottom cavity 61 can leak out through the lower through cavity 65 and the bottom through cavity 66. A sealing ring is provided on the movable partition 62 to ensure its sealing performance during movement.

[0062] In this embodiment, the refining, degassing, and deslagging machine body 1 is driven by the refining, degassing, and deslagging assembly 11, which extends a graphite rotor 12 into the molten aluminum pool 13 and rotates. This allows the graphite rotor 12 to blow inert gas into the molten aluminum, breaking it into a large number of dispersed bubbles, thereby achieving refining, degassing, and deslagging of the molten aluminum. It is worth noting that the molten aluminum refining, degassing, and deslagging machine body 1, the refining, degassing, and deslagging assembly 11, and the graphite rotor 12 are all currently available technologies and are therefore not described in detail in this disclosure.

[0063] Furthermore, as the graphite rotor 12 rotates, the slag in the molten aluminum pool 13 rises to the top of the molten aluminum. The rotation of the graphite rotor 12 also generates eddy currents within the molten aluminum pool 13, which in turn causes the slag on the surface of the molten aluminum pool 13 to rotate. Therefore, simply adjust the movable plate 25 so that it drives the slag scoop 3 to the surface of the molten aluminum in the molten aluminum pool 13 and aligns it with the flow of the molten aluminum. This automatically flushes the slag toward the slag scoop 3 through the molten aluminum flow. Furthermore, the slag scoop 3 is equipped with a molten aluminum filter 31. This allows the molten aluminum to pass through the filter 31 when the molten aluminum pushes the slag toward the slag scoop 3, while the slag remains on the filter 31.

[0064] Furthermore, when the user needs to remove slag from the molten aluminum pool 13, they simply drive the motor 23 to rotate the screw 24, thereby driving the movable plate 25 to move vertically, thereby driving the slag removal member 3 to the surface of the molten aluminum. The slag removal member 3 can now filter the residue on the surface of the molten aluminum, and the bottom bin 6 is now extended into the molten aluminum.

[0065] When the bottom bin 6 is extended into the molten aluminum, the air pressure prevents the molten aluminum from entering the bottom chamber 61 from the lower through-cavity 65 and the bottom through-cavity 66 and positioning it below the movable baffle 62. However, the molten aluminum can enter the bottom chamber 61 from the upper through-cavity 64 and position itself above the movable baffle 62. Under the pressure of the molten aluminum, it pushes the movable baffle 62 downward, thereby continuously pushing the air below the movable baffle 62 out of the lower through-cavity 65 and the bottom through-cavity 66, allowing the movable baffle 62 to move downward more easily. When the movable baffle 62 reaches the bottom of the bottom chamber 61, there is no air left in the bottom chamber 61, and the lower through-cavity 65 is positioned above the movable baffle 62.

[0066] As the movable partition 62 moves downward, it drives the top column 621, the connecting rod 622, and the rope-pressing member 623 to move downward synchronously. The rope-pressing member 623 can then press the traction rope 46 between the rope guide ring 52 and the connecting seat 53 downward, thereby pulling the traction rope 46 in the movable cavity 41 outward, thereby pulling the movable member 42.

[0067] When the movable member 42 is pulled by the traction rope 46, it can drive the push plate 32 to move synchronously through the connecting member 421. Thus, the push plate 32 can be pulled to one side of the slag scooping member 3 by the traction rope 46 pulling the movable member 42, and at this time, the first spring 43 is gradually stretched.

[0068] When the movable partition 62 moves to the bottom of the bottom cavity 61, the rope pressing member 623 presses the traction rope 46 to the lowest point. At this time, the traction rope 46 can pull the movable member 42 to the bottom of the locking cavity 40, and the first spring 43 is stretched to its limit. When the movable member 42 moves to the bottom of the locking cavity 40, the extension spring 423 can use its own elastic force to drive the wedge-shaped clamping member 424 upward, thereby moving the wedge-shaped clamping member 424 into the locking cavity 40. The movable member 42 is fixed by the mutual engagement between the wedge-shaped clamping member 424 and the locking cavity 40, thereby keeping the first spring 43 in a continuously stretched state.

[0069] Furthermore, when sufficient residue has collected on the molten aluminum filter 31, the user simply drives the motor 23 to control the screw 24 to rotate in the opposite direction, thereby driving the movable plate 25 and the slag scoop 3 upward. When the bottom bin 6 leaves the molten aluminum pool 13, the molten aluminum in the bottom bin 6 automatically flows out through the lower through cavity 65 and the bottom through cavity 66 and falls into the molten aluminum pool 13.

[0070] The user then only needs to move the residue collection box to the side of the slag scooping piece 3 through an external machine, and then continue to move the slag scooping piece 3 upward, so that the residue collection box is always located on one side of the slag scooping piece 3.

[0071] When the slag scoop 3 moves to the top, the fixed pressure column 27 can press the cross bar 7 and the top plate 71, so that the cross bar 7, the top plate 71, and the pressure piece 72 cannot move to the top, and the second spring 74 is compressed. This causes the relative positions of the cross bar 7, the top plate 71, and the pressure piece 72 to move downward, so that the pressure piece 72 can enter the clamping cavity 40, thereby pushing the wedge-shaped clamping piece 424 in the clamping cavity 40 into the clamping piece cavity 422. It is worth noting that when the slag scoop 3 is subsequently lowered, because the fixed pressure column 27 no longer presses the top plate 71, the cross bar 7, the top plate 71, and the pressure piece 72 can automatically move upward and reset due to the elastic force of the second spring 74.

[0072] By configuring the pressure member 72, when the slag scooping member 3 reaches its topmost position, the wedge-shaped clamping member 424 is automatically released from the clamping cavity 40, and the wedge-shaped clamping member 424 no longer secures the movable member 42. At this point, the first spring 43 automatically contracts and resets due to its own elastic force, thereby rapidly moving the movable member 42. As the movable member 42 moves, it drives the push plate 32 via the connecting member 421, thereby pushing the residue on the molten aluminum filter 31 into the residue collection box.

[0073] During the return of the first spring 43, the movable member 42 moves, pulling the traction rope 46 into the fixed chamber 4, thereby causing the pulled traction rope 46 to retract inward. As the traction rope 46 retracts, it simultaneously drives the rope-pressing member 623 upward, thereby simultaneously driving the connecting rod 622, the top column 621, and the movable partition 62 upward and resetting. This ensures that the slag removal member 3 automatically returns to its initial state before re-entering the molten aluminum to remove slag.

[0074] It is worth noting that the elastic force of the first spring 43 is greater than the force applied by the rope-pressing member 623 to the traction rope 46. This allows the movable member 42 to move toward the first spring 43 under normal conditions. When the bottom chamber 6 enters water, the molten aluminum exerts additional pressure on the movable partition 62, allowing the rope-pressing member 623 to exert greater force on the traction rope 46, thereby driving the movable member 42 to overcome the elastic force of the first spring 43 and move in the opposite direction. When the movable member 42 moves to the bottom of the cavity 40, the wedge-shaped clamping member 424 can secure the movable member 42, and at this time, the first spring 43 is fully stretched to load the first spring 43. Finally, the movable member 42 only needs to be released, and the elastic force of the first spring 43 can automatically drive the movable member 42 to move outward, thereby driving the push plate 32 to move and push out the residue.

[0075] In the present invention, the refining, degassing and slag removal of the molten aluminum can be achieved through the molten aluminum refining, degassing and slag removal machine body 1, and the molten aluminum filter 31 on the slag scooping part 3 can be used to filter the residue in the molten aluminum. The first spring 43 and the traction rope 46 pull the movable part 42 to drive the push plate 32 to move, so that the residue on the molten aluminum filter 31 can be pushed away by the push plate 32, and through the setting of the bottom bin 6, the push plate 32 can be automatically reset after entering the molten aluminum. This slag removal structure for the molten aluminum pool 13 is simple and convenient, and reduces the workload of the staff.

[0076] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
