Description

Technical Field

[0001] The invention relates to the technical field of aluminum melting furnace slag removal, in particular to an aluminum melting furnace processing slag removal device and a slag removal method. Background Art

[0002] Aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed according to aluminum smelting process. It can well meet the requirements of strict alloy composition, discontinuous production, large single furnace capacity and other requirements in aluminum smelting process, and achieves the effects of reducing consumption, reducing burning loss, improving product quality, reducing labor intensity, improving working conditions and improving production efficiency. It is suitable for intermittent operation.

[0003] During the smelting process, there will be aluminum ash of aluminum oxide on the surface of the aluminum liquid. If these aluminum ash are not removed, the strength and toughness of the parts will decrease during the later process of making aluminum alloy from the aluminum liquid. At the same time, the scrap aluminum material may contain impurities such as mud, sand, and plastic during smelting. Therefore, during the smelting process of the aluminum melting furnace, it is necessary to use a slag removal tool to screen out the aluminum ash and residue in the aluminum liquid;

[0004] In the prior art, a slag scraper made of high temperature resistant material is generally used for slag scraping. The slag scraper can be controlled by a mechanical arm to extend and scrape the slag. However, this slag scraper needs to be extremely careful during the slag scraping process. Aluminum ash is in the path from the furnace door to the recovery container. If the slag scraping range is too large, it is easy to cause splashing of aluminum liquid and dust, which not only pollutes the air, but also the sputtered aluminum liquid will be wasted, thereby reducing the efficiency of aluminum ash recovery.

A second electric telescopic rod 62 is fixed inside the second built-in groove 6, and the second electric telescopic rod 62 is controlled by the control room 11. A second extension frame 63 is fixed outside the output shaft of the second electric telescopic rod 62, and the second extension frame 63 is slidably connected to the second receiving groove 61. An extrusion plate 64 is fixed outside the end of the second extension frame 63 away from the load frame 22, and edge sealing 65 is fixed at both ends of the extrusion plate 64 close to the slag scraping plate 36.

[0037] During the specific operation, the recovery container is first placed in front of the furnace door of the aluminum melting furnace, and then the operator enters the control room 11, and controls the vehicle body 1 to move to the front of the furnace door through the control room 11, and then opens the furnace door, and then starts the first cylinder 2 and the second cylinder 21 through the control room 11, and the first cylinder 2 and the second cylinder 21 drive the load frame 22 to be ejected, and the load frame 22 drives the load tube 3 to be ejected, and the load tube 3 drives the first electric telescopic rod 33 and the second electric telescopic rod 62 to be ejected, and the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the slag plate 36 to be ejected, and the second electric telescopic rod 62 drives the second extension frame 63, the extrusion plate 64 and the edge sealing 65 to be ejected, and then ensure that the extrusion plate 64 and the slag plate 36 correspond to the height of the furnace door;

[0038] Then, the control room 11 controls the first electric telescopic rod 33 to start, and the first electric telescopic rod 33 is pushed out toward the furnace pool after being started. During the pushing out process, the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to move toward the furnace pool, and the support plate 35 drives the slag scraping plate 36 to move toward the furnace pool;

[0039] Then, the first cylinder 2 is controlled to return, so that the load frame 22 drives the load tube 3 to tilt toward the furnace pool under the limit of the second cylinder 21 and the pulling force of the first cylinder 2, so that the load tube 3 drives the first electric telescopic rod 33, the first extension frame 34 and the support plate 35 to tilt toward the furnace pool, so that the support plate 35 drives the slag plate 36 to enter the aluminum liquid in the furnace pool, and then, the first electric telescopic rod 33 is controlled to return through the control room 11, and the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to return, and the support plate 35 drives the slag plate 36 to return, and the slag plate 36 performs a slag removal operation on the aluminum ash in the aluminum liquid during the return process, so that the aluminum ash gradually approaches the furnace door under the drive of the slag removal plate 36;

[0040] Specifically, during the process of the slag scraping plate 36 returning to scrape the slag, the second electric telescopic rod 62 is started through the control room 11, so that the second electric telescopic rod 62 drives the second extension frame 63 to move toward the slag scraping plate 36, so that the second extension frame 63 drives the extrusion plate 64 and the edge sealing 65 to move toward the slag scraping plate 36, until the extrusion plate 64 drives the edge sealing 65 to be clamped into the interior of the slag scraping plate 36, so that the slag scraping plate 36, with the cooperation of the extrusion plate 64 and the edge sealing 65, wraps the aluminum ash scraped off by the slag scraping plate 36;

[0041] After the scraping plate 36, the extrusion plate 64 and the edge sealing 65 wrap the aluminum ash, the first cylinder 2 is controlled to be pushed out and restored to a state flush with the second cylinder 21, and then the load frame 22 is controlled to be restored to a horizontal state, so that the load frame 22 drives the load cylinder 3 to be restored to a horizontal state, so that the load cylinder 3 drives the first electric telescopic rod 33 and the second electric telescopic rod 62 to be restored to a horizontal state, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to be restored to a horizontal state, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the scraping plate 36 to be restored to a horizontal state, thereby separating the scraping plate 36, the extrusion plate 64 and the aluminum ash from the aluminum liquid;

[0042] Furthermore, after the scraping plate 36, the extrusion plate 64 and the aluminum ash are separated from the aluminum liquid, the first electric telescopic rod 33 and the second electric telescopic rod 62 are controlled to return synchronously, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the scraping plate 36 to return synchronously, and the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return synchronously, so that the scraping plate 36 and the extrusion plate 64 drive the aluminum ash to move toward the recovery container, until the scraping plate 36 and the extrusion plate 64 move to the top of the recovery container, and then the second electric telescopic rod 62 is controlled to return separately, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return, and the extrusion plate 64 releases the closed state with the scraping plate 36 during the return process, that is, the aluminum ash wrapped by the scraping plate 36 and the extrusion plate 64 can directly fall into the recovery container.

[0043] It should be noted that the slag removal plate 36 and the extrusion plate 64 are rectangular parallelepipeds, and the initial states of the first extension frame 34 and the slag removal plate 36 are both horizontal, so as to cooperate with the furnace door of the rectangular aluminum melting furnace to maximize the amount of slag removal by the slag removal plate 36.

[0044] Embodiment 2:

[0045] A motor 23 is fixed inside one side of the load frame 22, and the motor 23 is controlled by the control room 11. The output shaft of the motor 23 is fixed to the load cylinder 3. A guide frame 4 is fixed to the end of the slag plate 36 away from the control room 11, and a filtrate plate 5 is fixed to the end of the slag plate 36 close to the control room 11. The surface of the filtrate plate 5 is provided with filter holes. A guide plate 7 is fixed to the surface of the extrusion plate 64 close to the guide frame 4. The bottom length of the guide frame 4 is longer than the bottom length of the guide plate 7, and the top of the guide frame 4 is higher than the top of the guide plate 7.

[0046] During the specific operation, on the basis of the first embodiment, when the extrusion plate 64 and the edge seal 65 are inserted into the interior of the slag plate 36 and drive the aluminum ash to separate from the surface of the aluminum liquid, the motor 23 can be started through the control room 11, and the motor 23 drives the load cylinder 3 to rotate, and then the load cylinder 3 drives the first electric telescopic rod 33 and the second electric telescopic rod 62 to rotate synchronously to a vertical state, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the slag plate 36 to rotate synchronously to a vertical state, so that the second electric telescopic rod 62 drives the second extension frame 63, the extrusion plate 64 and the edge seal 65 to rotate synchronously to a vertical state, so that the flow guide frame 4 rotates to the top of the filtrate plate 5;

[0047] Specifically, when the slag plate 36 and the extrusion plate 64 are rotated to a vertical state, the aluminum ash is located above the filtrate plate 5, and then the aluminum liquid mixed in the aluminum ash is filtered out by the filtrate plate 5 and falls back into the aluminum liquid in the furnace pool, thereby reducing the time for the aluminum ash to enter the ash roasting machine and refine the aluminum liquid.

[0048] Furthermore, when filtering the aluminum liquid, the motor 23 can be controlled to continuously rotate forward and reverse, or rotate unidirectionally, so that the aluminum ash slides repeatedly under the wrapping of the slag plate 36, the extrusion plate 64 and the edge sealing 65. During the sliding process, the effect of filtering the aluminum liquid is improved, and the time and energy consumption of refining the aluminum liquid from the aluminum ash in the later stage are further reduced. Moreover, this process is carried out in the aluminum melting furnace, and there is no need to worry about dust and splashing of aluminum liquid.

[0049] After the aluminum liquid is filtered, the control room 11 can be used to control the first electric telescopic rod 33 and the second electric telescopic rod 62 to return, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the slag plate 36 to return, and the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return, so that the slag plate 36 and the extrusion plate 64 drive the aluminum ash to move synchronously toward the direction of the recovery container until the slag plate 36 and the extrusion plate 64 stay above the recovery container. At this time, the control motor 23 drives the load cylinder 3 to flip, so that the load cylinder 3 is linked to the slag plate 36 and the extrusion plate 64 to flip, and the filtrate plate 5 is located above the guide frame 4, and then the first cylinder 2 and the second cylinder 21 are controlled to return, so that the load frame 22 moves toward the recovery container, so that the load frame 22 drives the load cylinder 3 to move toward the recovery container, and then under the linkage of the load cylinder 3, the extrusion plate 64 and the slag plate 36 enter the interior of the recovery container;

[0050] At this time, the steps of Example 1 can be followed to control the return of the second electric telescopic rod 62, so that the second electric telescopic rod 62 drives the second extension frame 63 to return, so that the second extension frame 63 drives the extrusion plate 64 and the edge sealing 65 to separate from the slag plate 36, so that the extrusion plate 64 and the slag plate 36 are released from the closed state, so that the filtered aluminum ash can directly enter the recovery container. Under the obstruction of the recovery container, the slag plate 36 and the extrusion plate 64, the splashing and dust caused by the aluminum ash entering the recovery container are reduced, and the waste of aluminum liquid is reduced.

[0051] It should be noted that, when facing a cylindrical aluminum melting furnace, when the furnace door of the cylindrical aluminum melting furnace is larger than the area of ​​the filtrate plate 5, according to the operating steps of the first embodiment, the first cylinder 2 and the second cylinder 21 are started at the same time to drive the load frame 22 to be ejected, and it is ensured that the load frame 22 drives the load cylinder 3 to adjust the height, so that the load cylinder 3 drives the first electric telescopic rod 33, the first extension frame 34, the support plate 35 and the slag plate 36 to be higher than the cylindrical aluminum melting furnace, and then the first electric telescopic rod 33 is controlled to start alone, so that the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to move toward the cylindrical aluminum melting furnace, so that the support plate 35 drives the slag plate 36 to move to the top of the cylindrical aluminum melting furnace;

[0052] Next, the motor 23 is controlled to start, so that the motor 23 drives the load cylinder 3 to rotate, and then the load cylinder 3 is linked with the slag plate 36 to rotate to a vertical state. At this time, the rotation angle of the motor 23 is controlled so that the guide frame 4 is located above the filtrate plate 5. Then, the first cylinder 2 and the second cylinder 21 are controlled to return at the same time, so that the first cylinder 2 and the second cylinder 21 drive the load frame 22 to return and descend, so that the load frame 22 drives the load cylinder 3 to descend, and then the load cylinder 3 is linked with the slag plate 36 to descend, and the slag plate 36 drives the filtrate plate 5 to descend and enter the interior of the cylindrical aluminum melting furnace;

[0053] After the filtrate plate 5 enters the interior of the cylindrical aluminum melting furnace, the aluminum ash inside it can be salvaged, and during the salvaging process, the aluminum liquid in the aluminum ash is filtered out. Subsequently, by controlling the return stroke of the first electric telescopic rod 33, the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to return, and the support plate 35 drives the slag plate 36 and the filtrate plate 5 to return. During the return stroke, after the slag plate 36 and the filtrate plate 5 are moved to the top of the recovery container, the second cylinder 21 is controlled to return, so that the load frame 22 is tilted toward the direction of the second cylinder 21, and then the end of the load frame 22 close to the slag plate 36 is lifted up, and then the slag plate 36 drives the filtrate plate 5 to tilt toward the direction of the second cylinder 21, thereby allowing the aluminum ash salvaged from the surface of the filtrate plate 5 to enter the recovery container, thereby improving the versatility of the present invention, and at the same time, there is no need to flip the cylindrical aluminum melting furnace to cooperate with the salvage, thereby improving the efficiency of salvaging the slag aluminum ash.

[0054] Embodiment three:

[0055] A positioning rod 66 is fixed inside the side of the edge seal 65 close to the guide frame 4, and multiple groups of limit blocks 67 are fixed outside the positioning rod 66. Multiple loosening rods 68 are rotatably connected outside the positioning rod 66, and each loosening rod 68 is located on the inner side of a group of limit blocks 67. A limited height rod 69 is fixed to the inner wall of the edge seal 65 below the loosening rod 68.

[0056] During the specific operation, based on the first embodiment, when the extrusion plate 64 and the edge seal 65 are inserted into the first extension frame 34, the loosening rod 68 is guided by the guide frame 4 to tilt, and then the loosening rod 68 enters the interior of the scraping plate 36 and the extrusion plate 64 in an inclined state. When the scraping plate 36 and the extrusion plate 64 are completely closed, the guide frame 4 abuts against the guide plate 7;

[0057] Subsequently, the control room 11 controls the motor 23 to start, and the control motor 23 drives the load tube 3 to flip, so that the load tube 3 is linked with the slag plate 36 and the extrusion plate 64 to flip, so that the guide frame 4 is located below the filtrate plate 5. When the aluminum ash needs to be put into the recovery container, the control room 11 controls the second electric telescopic rod 62 to return, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return, and the extrusion plate 64 drives the edge sealing 65 to return;

[0058] During the return process of the extrusion plate 64 and the edge sealing 65, the guide frame 4 and the guide plate 7 gradually move away from each other, so that the guide frame 4 and the guide plate 7 are no longer in a state of abutting each other, that is, the slag plate 36 and the extrusion plate 64 are no longer in a closed state, and then the gap between the guide frame 4 and the guide plate 7 is used as a discharge port, so that the aluminum ash can fall into the inside of the recovery container through the gap between the guide frame 4 and the guide plate 7;

[0059] During the aluminum ash unloading process, the second electric telescopic rod 62 is controlled to perform repeated ejection and return strokes, so that the extrusion plate 64 drives the guide plate 7 to repeatedly reciprocate inside the slag removal plate 36. During the reciprocating movement, the spacing between the guide frame 4 and the guide plate 7 changes repeatedly, thereby preventing the aluminum ash from being blocked in the gap between the guide frame 4 and the guide plate 7, thereby ensuring the smoothness of the aluminum ash unloading;

[0060] At the same time, as the extrusion plate 64 repeatedly moves inside the slag removal plate 36, the extrusion plate 64 drives the positioning rod 66 and the loosening rod 68 to repeatedly move inside the slag removal plate 36, and the loosening rod 68 repeatedly deflects along the inclined surface of the guide frame 4 under the pressure of the aluminum ash and its own gravity, further ensuring the smoothness of the aluminum ash discharge;

[0061] Furthermore, when the distance between the guide frame 4 and the guide plate 7 changes repeatedly, the loosening rod 68 is located above the distance between the guide frame 4 and the guide plate 7, which hinders the discharge of aluminum ash, reduces the discharge speed of aluminum ash, and then reduces the potential energy of the falling aluminum ash, thereby reducing the impact force of the aluminum ash entering the recovery container, reducing the probability of aluminum liquid splashing and dust generation.

[0062] It should be noted that the height limiting rod 69 serves as a limiting structure, which has the effect of limiting the loosening rod 68, ensuring that the loosening rod 68 will not be stuck on the outside of the scraping plate 36 when the scraping plate 36 and the extrusion plate 64 are engaged.

[0063] A method for slagging an aluminum melting furnace, using the above-mentioned slagging equipment for aluminum melting furnace, comprises the following steps:
