DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0019] See also Figure 1-2, a vertical driving assembly is arranged on the main body 1 of the aluminum liquid refining, degassing and deslagging machine, which is composed of a slide rail and a vertical screw, and the refining, degassing and deslagging assembly 11 is driven to move by the vertical screw. A graphite rotor 12 is arranged on the refining, degassing and deslagging assembly 11 through the rotation of the main shaft, and the graphite rotor 12 is sent into the aluminum liquid pool 13. The rotating graphite rotor 12 can blow inert gas (such as argon or nitrogen) into the aluminum liquid and break it into a large number of dispersed bubbles. These bubbles absorb hydrogen in the aluminum liquid and adsorb oxidized slag by the gas partial pressure difference and the surface adsorption principle, and then float up with the bubbles and are brought out to the surface of the aluminum liquid, thereby realizing 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 liquid refining, degassing and deslagging machine main body 1, the refining, degassing and deslagging assembly 11 and the graphite rotor 12 are all prior art, so they are not elaborated in the present invention.

[0020] See also Figure 3-5 A lower fixed plate 2 is fixedly arranged on the outer side of the refining, degassing and deslagging assembly 11, and first guide columns 21 are fixedly arranged 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 arranged between the lower fixed plate 2 and the upper fixed plate 22, and the screw rod 24 is driven to rotate by the driving 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, so that the movable plate 25 can be moved vertically by the rotation of the screw rod 24, thereby driving the slag scooping piece 3 on the movable plate 25 to move synchronously.

[0021] A guide block 26 is fixedly arranged on the refining, degassing and deslagging assembly 11, and a guide cavity 251 is adapted to be opened on the movable plate 25 corresponding to the guide block 26, and a second guide column 252 is fixedly arranged in the guide cavity 251, and the second guide column 252 passes through the guide block 26. By setting the guide block 26, the movable plate 25 can be further guided to improve the stability of the movable plate 25 when moving.

[0022] A fixed pressure column 27 is fixed downwardly disposed at the bottom of the refining, degassing and deslagging assembly 11 , and the fixed pressure column 27 is aligned with the pressure piece 72 .

[0023] A plurality of mounting rods 253 are fixedly provided at the end of the movable plate 25, and screw holes are provided on the mounting rods 253, so that the slag scooping piece 3 can be fixedly assembled on the mounting rods 253 by screws. It is worth noting that the slag scooping piece 3 is provided with a variety of different sizes, and the sizes of the fixed bin 4, the fixed column 5, the bottom bin 6 and the cross bar 7 are all adapted and changed synchronously with the slag scooping piece 3. The user can install the corresponding adapted slag scooping piece 3 on the movable plate 25 according to the different sizes of the aluminum liquid pool 13.

[0024] See also Figure 6-9, an aluminum water filter 31 is fixedly arranged on the slag scooping part 3, and impurities in the aluminum water can be filtered through the aluminum water filter 31. A plurality of third guide pillars 33 are fixedly arranged on the slag scooping part 3, and the push plate 32 can be guided by the third guide pillars 33. And through the movable setting of the push plate 32, the impurities filtered and accumulated on the aluminum water filter 31 can be pushed away. It is worth noting that the aluminum water filter 31 is made of high temperature resistant materials such as glass fiber and ceramic foam, and it can be located in the high temperature aluminum water to filter impurities.

[0025] Fixed bins 4 are fixedly provided on both sides of the top of the slag scooping member 3 through support columns, and movable cavities 41 are provided inside the fixed bins 4. Fourth guide columns 44 are fixedly provided in the movable cavities 41, and movable members 42 are provided in the movable cavities 41 to be guided and moved by the fourth guide columns 44.

[0026] A first spring 43 is installed on one side of the movable cavity 41, and the other end of the first spring 43 is connected to the movable member 42, and the first spring 43 is located outside the fourth guide column 44. A traction rope 46 is fixedly connected to the other side of the movable member 42, and the other end of the traction rope 46 extends from the end of the fixed chamber 4. It is worth noting that the traction rope 46 is made of high temperature resistant materials such as glass fiber or ceramic fiber to ensure its normal use in a high temperature environment.

[0027] 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. Through the arrangement of the connecting member 421 on the movable member 42 on both sides, the push plate 32 can move synchronously with the connecting member 421.

[0028] See also Figure 6 , 10 -11, the top of the movable member 42 is provided with a card cavity 422 downwardly, and a wedge-shaped card 424 is movably provided in the card cavity 422. An upward extension spring 423 is installed at the bottom of the card cavity 422, 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 setting 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 off from the card cavity 422.

[0029] When the movable member 42 is located in the movable cavity 41 and moves, 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. In this way, the wedge-shaped clamping member 424 can be pushed out into the clamping cavity 40, so that the wedge-shaped clamping member 424 can be clamped in the clamping cavity 40, and the movable member 42 can be fixed below the clamping cavity 40.

[0030] The top of the fixed bins 4 on both sides is located on one side of the card cavity 40 and is fixedly and vertically provided with a fifth guide column 73, and the cross bar 7 is guided to move by the fifth guide column 73. The top of the fixed bin 4 is located on the outer side of the fifth guide column 73 and is provided with a second spring 74 upward, and the other end of the second spring 74 is connected to the cross bar 7.

[0031] Both ends of the cross bar 7 are fixed downwardly and vertically provided with pressing pieces 72, and the pressing pieces 72 are adapted and aligned with the wedge-shaped clamping piece 424. A top plate 71 is fixedly provided on the top of the cross bar 7, and the top plate 71 is adapted and aligned with the fixed pressure column 27. This allows the cross bar 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 cannot continue to move due to the setting of the fixed pressure column 27, while the movable plate 25 continues to move upward, so the top plate 71 can move downward relative to the movable plate 25 through the fixed pressure column 27. At this time, the cross bar 7, the top plate 71 and the pressing pieces 72 on both sides can all be synchronously moved into the clamping cavity 40, so that the wedge-shaped clamping piece 424 can be pressed into the clamping piece cavity 422, and the second spring 74 is compressed. In this way, the mutual clamping between the wedge-shaped clamping piece 424 and the clamping cavity 40 can be released, so that the fixed limit of the movable piece 42 can be released. 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 .

[0032] See also Figure 6 , 12 -16, the top of the fixed bin 4 is fixedly provided with a fixed column 5 vertically upward, and the top of the fixed column 5 is fixedly provided with a fixed seat 51. The inner wall of the fixed seat 51 is fixedly provided with a guide rope ring 52 and a connecting seat 53 on both sides, so that the traction rope 46 extending from the fixed bin 4 can pass through the guide rope ring 52 and then be connected to the connecting seat 53, so that the traction rope 46 between the guide rope ring 52 and the connecting seat 53 is flat.

[0033] The bottom chamber 6 is provided with a bottom cavity 61 inside, and a movable partition 62 is vertically and movably arranged in the bottom cavity 61. A fixing member 63 is fixedly arranged on the top of the movable partition 62, and a top column 621 is fixedly arranged vertically upward on the top of the fixing member 63. The top column 621 extends out from the bottom chamber 6, and a connecting rod 622 is fixedly arranged on the top of the top column 621, and a rope pressing member 623 is fixedly arranged 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 can press the traction rope 46 downward, so that the traction rope 46 can be pulled, and the movable member 42 can be pulled by the traction rope 46. When the rope pressing member 623 moves upward, the traction rope 46 can be automatically reset.

[0034] A plurality of vertical guide members 610 are fixedly arranged on the inner wall of the bottom cavity 61, and guide grooves 620 are adapted to be provided corresponding to the guide members 610 on the movable partition 62. The adaptation arrangement between the guide members 610 and the guide grooves 620 can improve the stability of the movable partition 62 during the activity.

[0035] Upper through cavities 64 are provided on both sides above the bottom cavity 61, lower through cavities 65 are provided on both sides below the bottom cavity 61, and a plurality of bottom through cavities 66 are provided at the bottom of the bottom cavity 61. This makes it impossible for the molten aluminum to enter the bottom cavity 61 from the lower through cavities 65 and the bottom through cavities 66 due to the air pressure below the movable partition 62 when the bottom bin 6 enters the molten aluminum. Therefore, there is still air in the bottom cavity 61 below the movable partition 62.

[0036] By setting the fixing member 63, the movable partition 62 can be separated from the top of the bottom cavity 61 by a certain distance, so that the movable partition 62 can be prevented from blocking the upper through cavity 64, so that the molten aluminum can enter the upper part of the movable partition 62 in the bottom cavity 61 through the upper through cavity 64. Therefore, the movable partition 62 can be pressed downward by the pressure of the molten aluminum above the movable partition 62, and the air below the movable partition 62 can be discharged through the lower through cavity 65 and the bottom through cavity 66, so that the top column 621, the connecting rod 622 and the rope pressing member 623 can be driven by the movable partition 62 to move downward synchronously.

[0037] When the bottom bin 6 moves upward out of the water, the water in the bottom chamber 61 can leak out through the lower through chamber 65 and the bottom through chamber 66. A sealing ring is provided on the movable partition 62 to ensure its sealing performance during movement.

[0038] In this embodiment, the graphite rotor 12 can be extended into the aluminum liquid pool 13 and rotated by driving the refining degassing and deslagging assembly 11 on the aluminum liquid refining degassing and deslagging machine body 1. Thus, the inert gas can be blown into the aluminum liquid through the graphite rotor 12 and broken into a large number of dispersed bubbles to achieve the refining, degassing and deslagging of the aluminum liquid. It is worth noting that the aluminum liquid refining degassing and deslagging machine body 1, the refining degassing and deslagging assembly 11 and the graphite rotor 12 are all existing technologies currently disclosed on the market, so they are not elaborated in the present invention.

[0039] Furthermore, during the rotation of the graphite rotor 12, the residue in the aluminum liquid pool 13 will float to the top of the aluminum liquid. And through the rotation of the graphite rotor 12, the aluminum liquid in the aluminum liquid pool 13 can be driven to generate eddy currents, thereby driving the residue on the surface of the aluminum liquid pool 13 to rotate. Therefore, it is only necessary to adjust the movable plate 25 so that it drives the slag scooping piece 3 to move to the surface of the aluminum liquid in the aluminum liquid pool 13 and to face the flow direction of the aluminum liquid, so that the residue can be automatically flushed onto the slag scooping piece 3 through the flow of the aluminum liquid. In addition, an aluminum liquid filter 31 is provided on the slag scooping piece 3, so that when the aluminum liquid flushes the residue toward the slag scooping piece 3, the aluminum liquid can pass through the aluminum liquid filter 31, and the residue will remain on the aluminum liquid filter 31.

[0040] Furthermore, when the user needs to remove slag from the aluminum liquid pool 13, the user only needs to control the screw rod 24 to rotate by the driving motor 23, thereby driving the movable plate 25 to move vertically, thereby driving the slag removal member 3 to move to the surface of the aluminum liquid. At this time, the residue on the surface of the aluminum liquid can be filtered by the slag removal member 3, and the bottom bin 6 is extended into the aluminum liquid.

[0041] When the bottom bin 6 is extended into the molten aluminum, due to the effect of air pressure, the molten aluminum will not enter the bottom chamber 61 from the lower through chamber 65 and the bottom through chamber 66 and will be located below the movable partition 62. However, the molten aluminum can enter the bottom chamber 61 from the upper through chamber 64 and will be located above the movable partition 62. Under the pressure of the molten aluminum, the molten aluminum can push the movable partition 62 downward, so that the air below the movable partition 62 can be continuously pushed out from the lower through chamber 65 and the bottom through chamber 66, so that the movable partition 62 can move downward more conveniently. When the movable partition 62 moves to the bottom of the bottom chamber 61, there is no air in the bottom chamber 61, and the lower through chamber 65 is located above the movable partition 62.

[0042] When the movable partition 62 moves downward, it can drive the top column 621, the connecting rod 622 and the rope pressing member 623 to move downward synchronously. Therefore, the traction rope 46 between the rope guide ring 52 and the connecting seat 53 can be pressed downward by the rope pressing member 623, so that the traction rope 46 in the movable cavity 41 can be pulled outward, thereby pulling the movable member 42.

[0043] 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 pulling the movable member 42 by the traction rope 46, and at this time, the first spring 43 is gradually stretched.

[0044] 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, and the traction rope 46 can pull the movable member 42 to the bottom of the clamping cavity 40, and the first spring 43 is stretched to the limit. When the movable member 42 moves to the bottom of the clamping cavity 40, the extension spring 423 can drive the wedge clamping member 424 to move upward through its own elastic force, so that the wedge clamping member 424 can be moved into the clamping cavity 40, so that the movable member 42 can be fixed by the mutual clamping between the wedge clamping member 424 and the clamping cavity 40, so that the first spring 43 can be continuously in a stretched state.

[0045] Furthermore, when enough residue is collected on the aluminum liquid filter 31, the user only needs to control the screw 24 to rotate in the opposite direction through the driving motor 23, thereby driving the movable plate 25 and the slag scooping member 3 to move upward. When the bottom bin 6 leaves the aluminum liquid pool 13, the aluminum liquid in the bottom bin 6 can automatically flow out through the lower through cavity 65 and the bottom through cavity 66 and fall into the aluminum liquid pool 13.

[0046] Then the user 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 upwards, so that the residue collection box is always located on one side of the slag scooping piece 3.

[0047] When the slag scooping member 3 moves to the top, the fixed pressure column 27 can be used to 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 makes the relative positions of the cross bar 7, the top plate 71 and the pressure piece 72 move downward, so that the pressure piece 72 can enter the clamping cavity 40, so that the wedge-shaped clamping piece 424 in the clamping cavity 40 can be pushed into the clamping cavity 422. It is worth noting that when the slag scooping member 3 is subsequently lowered, since 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 by the elastic force of the second spring 74.

[0048] By setting the pressing member 72, when the slag scooping member 3 moves to the top, the clamping between the wedge clamp 424 and the clamping cavity 40 can be automatically released, and the wedge clamp 424 no longer fixes the movable member 42. At this time, the first spring 43 can automatically shrink and reset by its own elastic force, thereby driving the movable member 42 to move quickly. When the movable member 42 moves, it can drive the push plate 32 to move through the connecting member 421, so that the residue on the aluminum liquid filter 31 can be pushed into the residue collection box by the movement of the push plate 32.

[0049] In addition, during the resetting process of the first spring 43, the traction rope 46 can be pulled into the fixed bin 4 by the movement of the movable member 42, thereby driving the pulled traction rope 46 to retract inward. During the retraction process of the traction rope 46, it can drive the rope pressing member 623 to move upward synchronously, thereby driving the connecting rod 622, the top column 621 and the movable partition 62 to move upward synchronously and reset through the rope pressing member 623. In this way, before the slag scooping member 3 enters the aluminum liquid again to scoop slag, it can automatically reset to the initial state.

[0050] 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, so that under normal conditions, the movable member 42 can move toward the first spring 43. When the bottom bin 6 enters the water, the aluminum liquid applies additional pressure to the movable partition 62, so that the rope pressing member 623 can apply a greater force to 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 card cavity 40, the wedge-shaped card member 424 can fix the movable member 42, and at this time the first spring 43 is fully stretched to load the first spring 43. Finally, it is only necessary to release the fixation of the movable member 42, and the elastic force of the first spring 43 can drive the movable member 42 to automatically move outward, so as to drive the push plate 32 to move and push out the residue.

[0051] In the present invention, the refining, degassing and slag removal of molten aluminum can be achieved through the molten aluminum refining, degassing and slag removal machine body 1, the molten aluminum filter screen 31 on the slag scooping part 3 can be used to filter the residue in the molten aluminum, and the first spring 43 and the traction rope 46 can traction the movable part 42 to drive the push plate 32 to move, so that the residue on the molten aluminum filter screen 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.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
