A turntable unit 2 is arranged in the treatment cylinder 1, said turntable unit 2 comprising a curing tray 201 and a drive assembly 202. The solidification plate 201 is arranged below the material inlet 101, and the driving assembly 202 is connected with the solidification plate 201. The outer side of the upper surface of the curing tray 201 is arranged in an upward inclined manner, i.e. an annular inclined surface is formed on the outer side of the upper surface of the curing tray 201.

The drive assembly 202 drives the solidification plate 201 to rotate, and molten slag is thrown into the inside of the processing cylinder 1 through the material inlet 101. Since the rotating solidification plate 201 is positioned below the material inlet 101, the charged molten slag falls onto the solidification plate 201, and the rotating solidification plate 201 throws the slag outward by the centrifugal force. Since the solidification plate 201 is provided with the annular inclined surface, slag slides outwards from the center of the upper surface of the solidification plate 201 under the action of centrifugal force, and is further thrown outwards along the inclined surface of the solidification plate 201, and rises and falls at the same time of outwards moving.

Referring to fig. 3 to 6, the turntable unit 2 further includes a water tank 203. The water tank 203 is fixedly arranged in the treatment cylinder 1, and a water inlet pipe 2031 and a water outlet pipe 2032 are arranged on the water tank 203.
Referring to fig. 4, the solidifying disk 201 is of a hollow structure, and a cooling chamber 2011 is provided inside thereof. The driving assembly 202 has a rotation shaft 2021, and the rotation shaft 2021 is used to coaxially connect the curing tray 201, so that the curing tray 201 rotates about the rotation shaft 2021. The rotating shaft 2021 is provided with a water return hole 2027, and the water return hole 2027 is arranged along the length direction of the rotating shaft 2021 and penetrates through two ends of the rotating shaft 2021.

The opening through which the water inlet pipe 2031 passes is located in the middle or upper portion of the water tank 203, the liquid level in the water tank 203 is lower than the opening, and cooling water in the water tank 203 cannot leak out of the opening.
One end of the water inlet pipe 2031, which is located inside the water tank 203, passes upward through the water return hole 2027 and extends into the cooling cavity 2011, so that the cooling water in the water inlet pipe 2031 is filled with the water supply device and can be directly conveyed into the cooling cavity 2011 of the solidification disk 201. The water inlet pipe 2031 penetrates the rotation shaft 2021, so that the rotation shaft 2021 is sleeved on the water inlet pipe 2031 and can rotate around the water inlet pipe 2031, and when the cooling liquid is conveyed into the solidification plate 201, the solidification plate 201 is kept to rotate.
The inner diameter of the water return hole 2027 is larger than the outer diameter of the water inlet pipe 2031, so that a space exists between the inner wall of the water return hole 2027 and the outer wall of the water inlet pipe 2031, and after the cooling liquid enters the cooling cavity 2011, the cooling liquid can flow back into the water return hole 2027 and then falls into the water tank 203 downwards.
The water outlet pipe 2032 is provided at the bottom of the water tank 203 and communicates with the inner space of the water tank 203. The cooling liquid passing through the water return hole 2027 falls into the water tank 203, and is discharged out of the water tank 203 through the water outlet pipe 2032, so that the cooling liquid is returned to the water supply device after cooling treatment, and the recycling of the cooling liquid is realized.
