The Chinese utility model patent with application No.202420663545X discloses an automatic turnover's aluminum liquid slag salvaging device aluminum liquid automatic slag salvaging device, which sets a filter disc corresponding to the pouring ladle diameter to clean the slag in the pouring ladle, increases the coverage area of the filter disc, improves the impurity cleaning effect, avoids the trouble of manually salvaging slag several times with a ladle, and the filter disc is driven by a lifting mechanism to complete automatic lifting and salvaging action, reducing the labor intensity of manual salvaging of workers. The workers can operate remotely from the salvaging site, improving the problem of long-term exposure of workers to dust environment and harming occupational health.

[0003] However, in actual application, since the filter disc and the lifting mechanism of the slag salvaging device are fixedly connected, i.e. the filter disc itself does not have a turnover function, when the filter disc enters the pouring ladle, the horizontally positioned filter disc will push the aluminum slag in the aluminum liquid downward to the bottom of the pouring ladle, which is not conducive to salvaging the impurities in the aluminum liquid, and there is a problem of incomplete salvaging of slag.

[0004] Therefore, it is necessary to develop a new type of slag salvaging device with a filter disc turnover function, so that when the filter disc enters the pouring ladle, the filter disc is turned to a vertical position and inserted into the aluminum liquid to avoid driving the impurities in the aluminum liquid downward and affecting the salvaging effect. When the filter disc approaches the bottom of the pouring ladle, the filter disc is turned to a horizontal position and upward to complete the salvaging operation. SUMMARY

[0011] Preferably, a counterweight is arranged on the filter disc, so that the filter disc can keep a horizontal state without external force.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-4 As shown, an automatic slag removal device for molten aluminum includes a filter disc 1 for slag removal. The filter disc 1 has filter holes 11. The filter disc 1 is connected to a frame 3 via a lifting mechanism 2, and the filter disc 1 has the freedom to rotate vertically on the lifting mechanism 2. During slag removal, the lifting mechanism 2 descends, causing the filter disc 1 to descend synchronously. When it reaches near the surface of the molten aluminum, the filter disc 1 rotates to an angle perpendicular to the surface of the molten aluminum and remains vertically inserted below the surface of the molten aluminum in the ladle. During slag removal, the filter disc 1 returns to a horizontal state, and the lifting mechanism 2 moves the filter disc 1 upward to remove the slag and impurities from the molten aluminum. In this embodiment, the vertical insertion of the filter disc 1 into the molten aluminum reduces the contact area between the filter disc 1 and impurities on the surface of the molten aluminum, effectively reducing the situation where impurities on the surface of the molten aluminum are pushed below the surface, thus improving the slag removal effect.

[0021] Preferably, the filter disc 1 is connected to a rotating shaft 12 in the diametrical direction, and the lifting rod 21 of the lifting mechanism 2 is provided with a shaft hole 22 corresponding to the rotating shaft 12. The rotating shaft 12 is rotatably connected to the shaft hole 22 to realize the rotatable connection between the filter disc 1 and the lifting mechanism 2.

[0022] Furthermore, such as Figures 3-4 As shown, a fan-shaped groove 23 is provided on the outer edge of the shaft hole 22. A limit stop 13 is provided on the rotating shaft 12 corresponding to the fan-shaped groove 23. The limit stop 13 is slidably connected to the fan-shaped groove and is used to limit the rotation angle of the rotating shaft 12, thereby limiting the flip angle of the filter plate 1. When the filter plate 1 moves downward, the limit stop 13 of the rotating shaft 12 slides to the upper limit position in the fan-shaped groove 23, so that the filter plate is vertically inserted into the aluminum liquid; when the filter plate 1 moves upward, the limit stop 13 of the rotating shaft 12 slides to the lower limit position in the fan-shaped groove 23, so that the filter plate moves upward in a horizontal state to remove slag.

[0023] Furthermore, such as Figures 1-2As shown, a toggle mechanism 4 is provided corresponding to the filter disc 1, used to automatically complete the flipping action of the filter disc 1. The toggle mechanism 4 includes a lever 41 with a hinged frame 3. The front end of the lever 41 extends to the position of the filter disc 1, and the tail end of the lever 41 is hinged to the frame 3. A limit frame 42 is provided corresponding to the lever 41 to limit the rotation angle of the lever 41. When the filter disc 1 moves downward, the bottom surface of the filter disc 1 will contact the lever 41. Under the limiting action of the limit frame 42, the lever 41 cannot flip downward, thus forming a toggle action on the downward filter disc 1, lifting the filter disc 1 to flip it and insert it into the molten aluminum as a vertical turntable; when moving upward, the upper end of the filter disc 1 will contact the lever 41 and push the lever 41 to flip upward, so that the filter disc 1 carrying aluminum dross can be smoothly separated from the molten aluminum. The setting of the toggle mechanism 4 realizes the automatic control of the flipping state of the filter disc 1, and no additional power device is required, making the structure simple and practical.

[0024] Furthermore, such as Figure 2 As shown, a counterweight 14 is provided on the filter disc 1 to keep the filter disc 1 in a horizontal state when no external force is applied. When the filter disc 1 moves downward and disengages from the lever 41, the filter disc 1 will automatically flip to a horizontal state under the bias of the counterweight 14, which facilitates upward slag removal and eliminates the need for a power source.

[0025] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
