[0031] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] Figure 1 This is a schematic diagram of the structure of the aluminum liquid slag removal device provided in this embodiment. Figure 2 This is a schematic diagram of the rake head structure 110 of the slag rake 100 of the aluminum liquid slag removal device provided in this embodiment. Figure 1 and Figure 2 As shown, this embodiment provides an aluminum liquid slag removal device, including a slag removal rake 100 and a mold box 200, the slag removal rake 100 includes a rake head structure 110 and a rake rod structure 120 connected to the rake head structure 110, the rake head structure 110 includes a rake head 111 for separating waste slag, the rake head 111 is plate-shaped, and the rake head 111 includes a metal skeleton, a ceramic layer and an aluminum layer from the inside to the outside; the mold box 200 is provided with a cavity 210, the cavity 210 can accommodate the rake head 111, and a casting space is formed between the outer surface of the rake head 111 and the inner surface of the cavity 210, and the casting space is used to hold the remaining aluminum liquid from the casting, wherein the aluminum liquid in the casting space forms an aluminum layer after cooling.

[0033] By sequentially arranging a metal skeleton, a ceramic layer and an aluminum layer from the inside to the outside of the rake head 111 of the rake head structure 110, the metal skeleton can be used to ensure the structural strength and rigidity of the rake head 111, and the deformation of the rake head 111 can be reduced; the ceramic layer can be used to improve the heat resistance of the rake head 111, ensure the reliability of the rake head 111 during the slag removal process, and reduce thermal deformation; the aluminum layer can be used to protect the molten aluminum liquid to a certain extent, so that during the slag removal process using the slag removal rake 100, the aluminum layer of the rake head 111 can be melted into the aluminum liquid without melting other metal elements. Moreover, the arrangement of the aluminum layer can also protect the rake head 111 to a certain extent.

[0034] Among them, the above-mentioned aluminum layer is formed by placing the rake head 111 in the cavity 210 of the mold box 200 and cooling the remaining aluminum liquid during casting. This arrangement can prevent the remaining aluminum liquid from directly cooling to form a large block structure while ensuring the formation of an aluminum layer on the surface of the rake head 111, thereby avoiding the waste of natural gas when the aluminum block formed by cooling is too thick and then melting again. In other words, the aluminum liquid slag removal device utilizes the mold box 200 to cover the remaining aluminum liquid on the surface of the rake head 111 to form an aluminum layer. This link can prevent the remaining aluminum liquid from directly forming a large block structure, thereby achieving thinning of the aluminum block. Compared with directly placing large-sized aluminum blocks into a natural gas heating furnace for melting, this can effectively save natural gas.

[0035] In this embodiment, the material of the metal frame is tungsten steel.

[0036] By setting the material of the metal frame of the drag head 111 to tungsten steel, the rigidity of the metal frame can be ensured, thereby further improving the rigidity of the drag head 111.

[0037] Specifically, the metal skeleton is made of special tungsten steel, model YG20.

[0038] In this embodiment, the material of the ceramic layer is silicon carbide.

[0039] By setting the material of the ceramic layer of the drag head 111 to silicon carbide, the heat resistance of the drag head 111 can be further improved, and thermal deformation of the drag head 111 during use can be avoided.

[0040] It should be noted that the above “avoiding thermal deformation of the drag head 111 during use” means: avoiding thermal deformation of the drag head 111 substrate mainly composed of a metal skeleton and a ceramic layer, and the aluminum layer will melt into the aluminum liquid during use.

[0041] Please continue to refer to Figure 2In this embodiment, the rake head structure 110 may further include a first support column 112 and a second support column 113. Specifically, the first support column 112 and the second support column 113 are both fixedly disposed on the rake head 111, and the first support column 112 and the second support column 113 are arranged at intervals, and the first support column 112 and the second support column 113 are used to support the rake head 111 on the ground.

[0042] By providing a first support column 112 and a second support column 113 connected to the rake head 111, the rake head 111 can be supported on the ground to prevent the rake head structure 110 from bumping against the ceramic layer when it is placed, thereby protecting the rake head structure 110 to a certain extent and extending the service life of the rake head structure 110.

[0043] Specifically, in this embodiment, the first support column 112 and the second support column 113 are both rectangular parallelepiped structures. In other embodiments, the first support column 112 and the second support column 113 can also be cylindrical structures.

[0044] It should be noted that, in this embodiment, the material of both the first support column 112 and the second support column 113 is the same as the material of the rake head 111 .

[0068] Afterwards, the staff can operate the forklift, extend the fork of the forklift into the first rectangular hole 1235 and the second rectangular hole 1236 of the connecting head 123 of the rake rod structure 120, and adjust the position of the slag rake 100 to slowly put the rake head 111 into the cavity 210 of the mold box 200; then, pour the remaining aluminum liquid from the casting along the gate nest 240, and use the straight runner 251 and the inner runner 252 to guide the aluminum liquid to the cavity 210, so that the aluminum liquid fills the space between the outer surface of the rake head 111 and the inner surface of the cavity 210, and after cooling for a period of time, open the mold box 200, at this time, an aluminum layer is formed on the outside of the rake head 111. Afterwards, the staff continues to operate the forklift to raise the slag rake 100, and by adjusting the telescopic length of the extension arm, the rake head 111 can be used to remove slag from the deep aluminum liquid in the melting furnace, and by adjusting the height of the fork, the rake head 111 can be used to remove impurities on the surface of the aluminum liquid, so as to achieve the purpose of aluminum liquid slag removal.

[0069] When the rake head structure 110 is damaged and cannot be used normally, the first support column 112 and the second support column 113 can be used to place the slag rake 100 on the ground, and the limiting effect of the threaded connection 130 can be released, and the rake head structure 110 can be removed from the rake rod structure 120. After replacing the new rake head structure 110, repeating the above steps can put the aluminum liquid slag removal device back into normal production, and the damaged rake head structure 110 can be returned to the factory for repair alone, which will not affect the production progress.

[0070] In summary, the aluminum liquid scraping device provided in the present application uses special tungsten steel to form the metal skeleton of the rake head 111, which can improve the rigidity of the rake head 111; by coating the silicon carbide ceramic layer on the outside of the metal skeleton, the heat resistance of the rake head 111 can be improved; by coating the aluminum layer on the outside of the silicon carbide ceramic layer, not only can the silicon carbide ceramic layer be protected, but also the heat resistance and rigidity of the rake head 111 can be further improved, and the rake head 111 can be prevented from being deformed by heat or melted into the aluminum liquid during use, thereby affecting the quality of the aluminum liquid. At the same time, the outermost aluminum layer of the rake head 111 will also gradually melt during the scraping process, which is more efficient than directly putting large-sized aluminum blocks into the melting furnace for melting.
