A brush 26 is fixedly connected to one end of the column 25 away from the rotating rod 24. The rotating motor 21 will drive the rotating rod 22 at its output end to rotate, so that the rotating fan blade 23 rotates synchronously inside the melting kiln 17. Also, since a rotating rod 24 is fixedly connected to the surface of the rotating rod 22, and a column 25 is fixedly connected to the top of the rotating rod 24, due to the rotation of the rotating rod 22, the inside of the melting kiln 17 can be cleaned.

[0024] The lower end of the feeding port 13 is fixedly connected to a conveying pipe 16. The inner wall bottom end of the melting furnace 1 is fixedly connected to a steam heating box 15. The upper end of the steam heating box 15 is fixedly connected to a melting kiln 17. The melting kiln 17 is located directly above the steam heating box 15. The rotating rod 22 also rotates through the melting kiln 17.

[0025] A control mechanism 3 is arranged on the inner wall of the melting kiln 17. The control mechanism 3 includes a rotating shaft 33 that rotates through the inner wall of the melting kiln 17. A connecting piece 32 is fixedly connected to one end of the rotating shaft 33 away from the melting kiln 17.

Before adding, first open the steam heating box 15 at the bottom of the melting furnace 1, and then start the rotating motor 21. The rotating motor 21 will drive the rotating rod 22 at its output end to rotate, so that the rotating fan blades 23 rotate synchronously inside the melting kiln 17. Also, since a rotating rod 24 is fixedly connected to the surface of the rotating rod 22, and a column 25 is fixedly connected to the top of the rotating rod 24, due to the rotation of the rotating rod 22, the inside of the melting kiln 17 can be cleaned.

Also, since the device is fixedly connected with a temperature sensor 44 at the upper end of the inner wall of the melting furnace 1, when the melting operation is completed, it will activate the storage pipe 42 on the liquid nitrogen tank 41, and then eject liquid nitrogen from the injection port 43. This can reduce the temperature of the melted product and maintain a stable physical state, facilitating subsequent marking construction. The device is also provided with a safety valve 31, which can be rotated when necessary to ensure the safety of operators and equipment to the greatest extent.
