[0022] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0023] The existing slag removal method is to manually hold a spoon-shaped collecting device to scoop out the slag floating on the surface of the molten aluminum. Only a portion can be scooped out at a time, which is inefficient. Since the workers wear protective clothing and are in close contact with the molten aluminum in the crucible for a long time, safety risks are prone to occur and the labor intensity is high.

[0024] In order to solve the above problems, Figure 1 to Figure 2 As shown, the present invention provides a slag removal device, including a rotating motor 1, a slag removal frame 2 and a trough body 4, wherein both sides of the trough body 4 are respectively connected to the slag removal frame 2, the rotating motor 1 is installed on the symmetry axis of the slag removal frame 2, the rotating motor 1 drives the slag removal frame 2 to rotate, a lower bottom surface 42 is formed on the trough body 4, the lower bottom surface 42 can be immersed in the lower side of the aluminum liquid level in the furnace body, a notch is provided on the upper side of the lower bottom surface 42, the notch can store slag, the control terminal can control the rotating motor 1 to rotate the slag removal frame 2, and the rotating motor 1 is installed on the lower side of the crane.

[0025] The crane drives the slag removal device to move, and the slag on the surface of the aluminum liquid is collected into the tank body 4 along the notch by rotating the rotating motor 1 for one rotation. The efficiency of one rotation is higher than that of manual scooping, which can improve the scooping efficiency and keep workers away from the surface of the aluminum liquid, reducing safety risks and work intensity. By rotating at the symmetric axis position, the area covered by the tank body 4 overlaps with the surface of the aluminum liquid in the crucible, and all the slag can be collected.

[0026] The trough body 4 of the present invention is connected to the slag removal frame 2 through a swing blade motor 5. The swing blade motor 5 can drive the trough body 4 to rotate axially around the length direction. The control terminal is electrically connected to the swing blade motor 5.

[0027] The direction of the notch can be controlled by the swing blade motor 5. When the rotating motor 1 controls the slag removal frame 2 to rotate, the notch is directed toward the aluminum liquid surface, so that the slag can be accumulated in the trough body 4, thereby improving the scooping efficiency. When the scooping is completed, the trough body 4 is rotated to make the notch face upward. When the crane lifts the slag removal device away, the slag in the trough body 4 can be prevented from falling downward, thereby making the surface of the aluminum liquid in the furnace cleaner.

[0028] The trough body 4 also includes an upper surface 41, and an inclination sensor 6 is arranged on the upper side of the upper surface 41. The inclination sensor 6 can measure the inclination angle of the upper surface 41. The control terminal can receive the signal transmitted by the inclination sensor 6, and can analyze the angle information to further adjust the trough body 4 to an angle suitable for its current working state, thereby facilitating automatic control and saving workers' work intensity.

[0029] The material of the tank body 4 of the present invention is graphite, and the outer surface of the tank body 4 is coated with alumina. Graphite can withstand high temperatures, and the alumina coated on the surface can avoid contaminating the aluminum liquid in the crucible, so that the aluminum liquid can maintain a pure state.

[0030] The slag scraping frame 2 of the present invention includes a cross beam 21, a first telescopic rod 22, a second telescopic rod 23 and a vertical rod assembly. The first telescopic rod 22 and the second telescopic rod 23 are installed on both sides of the cross beam 21. The first telescopic rod 22 and the second telescopic rod 23 are respectively connected to the vertical rod assemblies, and the vertical rod assemblies are respectively connected to both sides of the trough body 4. The rotating motor 1 is connected to the cross beam 21, and the first telescopic rod 22 and the second telescopic rod 23 move along the length direction of the cross beam 21.

[0031] In this way, the lateral spacing of the slag removal frame 2 can be changed, and it can be applicable to crucibles of different sizes, can fit with crucibles of different sizes, improve versatility, and cover the entire area of ​​the liquid surface in the crucible after one rotation, so that the slag removal effect is better. At the same time, the trough body 4 of the present invention has multiple groups and different lengths, which is convenient for connecting with the slag removal frame 2 after the length is changed.

[0032] Transverse motors 7 are arranged on both sides of the crossbeam 21. The front end of the transverse motor 7 is rotatably connected to a first gear, which is respectively engaged with the first telescopic rod 22 and the second telescopic rod 23. The transverse motor 7 is connected to a control terminal.

[0033] By electrically connecting the control terminal to the transverse motor 7, the rotation angle of the first gear is controlled, and then the moving distance of the first telescopic rod 22 and the second telescopic rod 23 is controlled, so that the degree of automatic adjustment of the slag scraping device is higher and the work intensity of the workers is reduced.

[0034] The vertical rod assembly includes an extension rod 24 and a vertical rod 25, the vertical rod 25 is fixed to the first telescopic rod 22 and the second telescopic rod 23 respectively, one end of the extension rod 24 is slidably connected to the vertical rod 25, and the other end is connected to the tank body 4. The vertical height of the slag removal frame 2 can be changed by the extension rod 24, so that the tank body 4 can be accurately immersed in the aluminum liquid and the slag can be collected through the notch.

[0035] A vertical motor 8 is installed on the vertical rod 25. The front end of the vertical motor 8 is rotatably connected to a second gear, which meshes with the vertical rod 25. The number of rotations of the vertical motor 8 is controlled by the control terminal to facilitate the control of the moving distance of the extension rod 24. A rangefinder 9 is installed on the upper end of the vertical rod 25. The rangefinder 9 can measure the distance between the tank body 4 and the liquid surface. The rangefinder 9 is connected to the control terminal to make the falling position of the tank body 4 more accurate, improve work efficiency, save manpower, and automatically calibrate, so that work efficiency is higher.

[0036] The slag removal frame 2 of the present invention is provided with a visual inspection device 3, which detects and determines whether the tank body 4 can enter the furnace body. The visual inspection device 3 is connected to the control terminal.

[0037] The present invention also includes the following working method:

[0038] First, the lateral distance of the slag scraping frame 2 is adjusted by the lateral motor 7 so that the lateral distance of the slag scraping frame 2 is the same as the diameter of the aluminum liquid surface in the crucible, and then the trough body 4 of the corresponding length is installed, and the crane is controlled to move the slag scraping device to the top of the crucible. At the same time, the control terminal rotates the trough body 4 through the swing blade motor 5 so that the notch of the trough body 4 faces the liquid surface, and the visual inspection device 3 determines whether the trough body 4 is aligned with the edge of the liquid surface by obtaining the position of the crucible and the trough body 4, so as to avoid the limitation of the trough body 4 and the crucible; when the alignment is determined, the control terminal determines the height between the trough body 4 and the liquid surface through the rangefinder 9, and adjusts the height of the trough body 4 by controlling the vertical motor 8 so that the lower bottom surface 42 is immersed in the aluminum liquid, and then the slag scraping frame 2 is rotated to collect the slag, and finally the notch is turned upward by the swing blade motor 5 to prevent the slag from falling back into the liquid surface, and it is lifted back by the crane.
