Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a slag removal device for rare earth magnesium alloy production, comprising a top plate 4, a furnace 5 is arranged in the middle of the lower surface of the top plate 4, a slag removal mechanism 8 and a stirring mechanism 7 are arranged on the upper surface of the top plate 4, a slag discharge bucket 9 is rotatably connected to the other end of the upper surface of the top plate 4, and the feeding end of the slag discharge bucket 9 is arranged above the furnace 5;

[0023] The slag removal mechanism 8 includes a second cylinder 81, a connecting angle plate 82 and a protective frame 83. The second cylinder 81 is installed at one end of the lower surface of the top plate 4. The telescopic end of the second cylinder 81 passes through the top plate 4 and is fixedly connected to the lower surface of the connecting angle plate 82. The protective frame 83 is fixedly connected to the lower end of one side of the connecting angle plate 82. The protective frame 83 is arranged in a circular ring shape. The lower end of the protective frame 83 is fixedly connected to a filter carbon mesh 84. One end of the filter carbon mesh 84 is provided with a slag hole 85. The protective frame 83 is arranged at an angle. A slag discharge hole 86 is opened on the outer side of the protective frame 83 away from the connecting angle plate 82.

[0024] The horizontal height of the slag hole 85 is greater than the horizontal height of the slag discharge hole 86, and the outer diameter of the guard frame 83 is smaller than the inner diameter of the opening end of the furnace 5, which facilitates the guard frame 83 to fall down to collect and process the slag in the alloy liquid, thereby improving practicality.

[0025] The stirring mechanism 7 includes a first right-angle plate 71, a second right-angle plate 72 and a driving motor 73. The first right-angle plate 71 is fixedly connected to the upper surface of the top plate 4, the second right-angle plate 72 is fixedly connected to one end of the lower surface of the second right-angle plate 72, the driving motor 73 is installed on one side of the second right-angle plate 72, and the output shaft of the driving motor 73 is connected to the turntable 74. The first right-angle plate 71 and the second right-angle plate 72 improve the stability of the driving motor 73 driving the telescopic carbon rod 77 to rise and fall, thereby improving the efficiency of stirring the alloy liquid.

[0026] A rotating shaft for transmission connection to the output shaft of the driving motor 73 is fixedly connected to one side of the turntable 74, and a fixing pin 75 is fixedly connected to the other side of the turntable 74. The rotating shaft is driven by the driving motor 73 to drive the turntable 74 to rotate, thereby driving the fixing pin 75 to move in a circle, ensuring that the telescopic carbon rod 77 can move up and down, so that the flip plate 78 stirs the alloy liquid. The flip plate is made of the same material as the carbon rod.

[0027] A telescopic carbon rod 77 is slidably inserted into the upper surface of the second right-angle plate 72, and the lower end of the telescopic carbon rod 77 is fixedly connected to a flap 78, and the upper end of the telescopic carbon rod 77 is rotatably connected to a connecting rod 76, and the upper end of the connecting rod 76 is rotatably connected to a fixed pin 75. When the fixed pin 75 is driven to rotate by the turntable 74, the connecting end of the connecting rod 76 and the fixed pin 75 makes a circular motion, and then the lower end of the connecting rod 76 drives the telescopic carbon rod 77 to do a lifting motion, so that the telescopic carbon rod 77 moves along the circular hole on the second right-angle plate 72, thereby improving the lifting stability of the telescopic carbon rod 77.

[0028] A circular hole is provided in the middle of the upper surface of the filter carbon mesh 84 for the telescopic carbon rod 77 to pass through. A discharge hopper 6 is provided on one side of the top plate 4. The discharge hopper 6 and the first right-angle plate 71 are arranged in the same plane, and the connecting angle plate 82 and the slag discharge hopper 9 are arranged in the same plane. The discharge hopper 6 and the slag discharge hopper 9 are staggered and vertically arranged, which makes it convenient to pour the alloy liquid and discharge the slag, reduces the space occupied, and improves practicality.

[0029] One end of the lower surface of the top plate 4 is rotatably connected to the support plate 2, and the lower end of one side of the support plate 2 is fixedly connected to the fixed base frame 1. The first cylinder 3 is rotatably installed on both sides adjacent to the support plate 2 and the fixed base frame 1. The telescopic end of the first cylinder 3 is rotatably connected to the lower surface of the top plate 4. The telescopic end of the first cylinder 3 is convenient for changing the inclination angle of the top plate 4, thereby facilitating the pouring of the alloy liquid in the furnace 5, thereby improving practicality and reducing the labor intensity of the staff.

[0030] When in use, the second cylinder 81 drives the connecting angle plate 82 to descend, thereby driving the protective frame 83 to immerse in the alloy liquid in the melting furnace 5, so that the stirring component drives the slag in the alloy liquid to float, and then the slag floats to the surface of the alloy liquid through the slag hole 85. After being immersed in the alloy liquid for 10-30 seconds, the second cylinder 81 is reset, and then the protective frame 83 is against the slag discharge bucket 9 during the rising process, so that the slag discharge bucket 9 is flipped at a certain angle. When the protective frame 83 is raised to the highest position, the slag discharge bucket 9 falls, and then the slag on the filter carbon mesh 84 is collected and processed through the slag discharge hole 86 and the slag falling bucket, thereby improving the efficiency of slag cleaning.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
