In the process of using melting furnaces for smelting and casting and rolling aluminum and aluminum alloys, in the aluminum alloy smelting link, with the dissolution and oxidation slag of alloy additives, intermediate alloys, and refining agents in the aluminum liquid and the residue contained in the electrolytic aluminum liquid itself, more impurities will be generated in the smelting furnace before and after refining, floating on the surface of the melt, and these impurities need to be removed in time; during the slag removal operation, a slag removal vehicle is usually used to probe the slag removal rake into the smelting furnace to remove the floating residue on the upper layer.

[0003] For example, the patent with announcement number CN209143611U announces a slag removal forklift, including a forklift, a slag rake and a counterweight mechanism.

The slag rake is driven by the forklift to move so that the rake head can remove slag from the cast aluminum alloy melting furnace, replacing the existing manual slag removal, reducing labor costs, reducing operating risks, avoiding safety accidents, high safety, high work efficiency, short slag removal time, and improving slag removal quality; in addition, a counterweight mechanism is provided on the forklift to effectively avoid the top-heavy problem caused by the slag rake being too long, reduce the shaking of the slag rake during the slag removal process, and increase the stability of the slag rake and the forklift.

[0004] However, the slag removal device in the above technology still has the following problems:

[0005] During the slag removal operation, the slag rake repeatedly scoops up the floating slag in the smelting furnace to complete the slag removal operation. However, the slag rake is only applicable to rectangular smelting furnaces. In a circular smelting furnace, the slag on the curved inner wall of the smelting furnace cannot be successfully cleaned, and the applicability is poor. Utility Model Content

[0008] Furthermore, when the rake plate abuts against the slag holding opening, a certain gap is left at the bottom of the slag holding opening.

[0009] Furthermore, the bottom surface of the slag box is designed to be sloped, and the slope is inclined downward toward the slag opening.

[0013] Furthermore, the lifting rod is a U-shaped rod, and an arc groove is provided on the side wall of the lifting rod close to one end of the slag box, and the sleeve and the slag removal motor are fixedly connected to the arc groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 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 of the embodiments.

[0022] See also Figure 1 - Figure 4 A slag removal device for an aluminum alloy smelting furnace comprises a rake plate 1, one end of the rake plate 1 is connected to a flip assembly, the other side of the flip assembly is connected to a slag box 2, a slag opening 201 is provided on the side of the slag box 2 close to the rake plate 1, the rake plate 1 is matched with the slag opening 201, and a lifting rod 3 is connected to the outer wall of one side of the slag box 2.

[0023] like Figure 1 - Figure 4 As shown, the slag removal device of an aluminum alloy smelting furnace in the utility model is similar in structure to the existing slag removal device of an aluminum alloy smelting furnace, such as a slag removal forklift disclosed in the patent with publication number CN209143611U. The main improvement of the utility model is that the slag in the circular smelting furnace can be cleaned, further improving the applicability of the slag removal device, such as Figures 1 to 4 As shown, when the slag removal device for an aluminum alloy smelting furnace of the utility model is in use, the end of the lifting rod 3 away from the rake plate 1 is fixed to the boom of a slag removal forklift or a crane, and the slag box 2 and the rake plate 1 at the other end of the lifting rod 3 are sent into the circular aluminum alloy smelting furnace by the forklift or the crane, and then the rake plate 1 is driven to open outward from the side of the slag opening 201 of the slag box 2 by the flip assembly, and then the rake plate 1 is driven to flip and move toward the slag opening 201 by the flip assembly, so that the smelting waste slag on the inner wall of the smelting furnace is scraped to the slag box 2, and the slag is removed by the slag removal forklift. The slag is scraped into the slag box 2 through the opening 201 for storage, and the end of the flipped rake plate 1 can also scrape the side wall of the circular smelting furnace, so as to scrape off the slag attached to the inner wall of the smelting furnace, thereby improving the slag scraping effect inside the smelting furnace. When the inner wall of the slag box 2 is full of smelting waste slag, the rake plate 1 is covered at the slag opening 201 by the flip assembly, so as to prevent the smelting waste slag in the slag box 2 from leaking out, and then the lifting rod 3 is lifted upward again by a forklift or a crane, so as to lift the slag box 2 full of waste slag out of the circular smelting furnace.

[0024] like Figure 1 - Figure 4 As shown, when the rake plate 1 contacts the slag opening 201, a certain gap is left at the bottom of the slag opening 201. When the rake plate 1 pushes the waste slag toward the slag box 2, a part of the melt in the furnace will inevitably enter the slag box 2. At this time, the melt can flow out of the slag box 2 through the gap between the bottom of the slag box 2 and the rake plate 1, so as to prevent the melt from being carried out of the smelting furnace by the slag box 2.

[0025] like Figure 1 - Figure 4 As shown, the bottom surface of the slag box 2 is designed as a slope, and the slope is inclined downward toward the slag opening 201. After the slag box 2 filled with smelting waste slag is taken out, the rake plate 1 covering the slag opening 201 is opened to leak out the slag opening 201. At this time, the smelting waste slag inside the slag box 2 can slide down from the slag box 2 more smoothly through the bottom inclined downward, thereby emptying the slag box 2, which is convenient for quickly carrying out another slag scavenging operation.

[0026] like Figure 1 - Figure 4 As shown, the flip assembly includes a sleeve 4 and a connecting rod 5, the outer wall of the sleeve 4 is fixedly connected to the outer wall of the slag box 2 near the slag opening 201, the outer wall of the connecting rod 5 is rotatably connected to the inner wall of the sleeve 4, the top of the connecting rod 5 is connected to the rake plate 1, the top of the rake plate 1 near the end of the connecting rod 5 is connected to a power assembly, and the power assembly is connected to the lifting rod 3. Start the power assembly to drive the rake plate 1 to rotate inside the sleeve 4 through the connecting rod 5, thereby completing the flipping and slagging operation of the rake plate 1 on the side of the slag box 2.

[0027] like Figure 1 - Figure 4 As shown, the power assembly includes a slag scraping motor 6 and a rotating rod 7, the slag scraping motor 6 is fixedly connected to the lifting rod 3, one end of the rotating rod 7 is fixedly connected to the rake plate 1, and the other end is fixedly connected to the output end of the slag scraping motor 6, and the rotating rod 7 and the connecting rotating rod 5 are the same rotating axis. The slag scraping motor 6 is fixed to the lifting rod 3 and remains stationary. When the slag scraping motor 6 is started, the rotating rod 7 is driven to rotate, thereby driving the rake plate 1 to rotate and scrape the slag.

[0028] like Figure 1 - Figure 4 As shown, the end of the rake plate 1 close to the connecting rod 5 is provided with a matching groove 101, the side wall of the matching groove 101 is slidably connected to the outer wall of the sleeve 4, and the top of the connecting rod 5 is fixedly connected to the top of the matching groove 101. Through the arrangement of the matching groove 101, the rake plate 1 is more closely fitted with the slag holding port 201 when the slag is flipped over for slag removal, so that the slag removal operation is smoother.

[0029] like Figure 1As shown, the lifting rod 3 is a U-shaped rod, and an arc groove 301 is provided on the side wall of the lifting rod 3 near one end of the slag box 2, and the sleeve 4 and the slag removal motor 6 are fixedly connected to the arc groove 301. By designing the lifting rod 3 to be U-shaped, when the lifting rod 3 is connected to a forklift, the forklift can smoothly lift the slag box 2 at the other end of the lifting rod 3 upward and send it into the circular smelting furnace.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
