The inner wall of the tub 510 is fixedly provided with a third helical blade 540, and the helical direction of the third helical blade 540 is opposite to the helical direction of the second helical blade 530.

The heated material in the front furnace body 210 enters the rear furnace body 220 through the first butterfly valve 240 at the tail end. The material entering the rear furnace body 220 is firstly dispersed into the rear furnace body 220 by the conical cover 520 at the front end, and the material in the front furnace body 210 is lifted to the upper section of the front furnace body 210 by the first spiral blade 280 through the second spiral blade 530 which is reversely arranged, and meanwhile, the material in the inner wall of the rear furnace body 220 is slowly dispersed to the tail end of the rear furnace body 220 through the second spiral blade 530, the inner wall of the rear furnace body 220 and the gap between the barrel body 510. Compared with the traditional material which directly slides to the tail end of the rear furnace body 220, the sliding residence time of the material on the inner wall of the rear furnace body 220 is increased, and the cooling quality of the material is improved.

When more material remains in the rear section of the rear furnace body 220, the rotating third helical blade 540 inside the rotating tub body 510 rotates the material in the rear section inside the rear furnace body 220 along the inner wall of the tub body 510 to the inside of the tub body 510, so that the rear furnace body 220 can efficiently cool and process more material at one time.

After the material cooling treatment is finished, the second butterfly valve 250 is opened, the rotary driving assembly 120 drives the rear furnace body 220 to drive the second helical blade 530 to rotate for a period of time for discharging, and then the rotary driving assembly 120 drives the rear furnace body 220 to reversely rotate, namely, the material in the barrel 510 is driven to rotate along the third helical blade 540 for discharging, and then the whole material in the rear furnace body 220 is discharged.

The rotating front furnace body 210 drives the internal material turning plate 550 to turn the material in the material cavity 560. That is, the front furnace body 210 rotates to drive the turning plate 551 to turn over the material at the bottom of the material taking cavity 560, the material is turned over along the turning plate 551 and gradually falls down, the material on part of the turning plate 551 can fall onto the next turning plate 551, the material can be burnt and heated by the burner 270 while the material is turned inside the material cavity 560, and the heating efficiency of the material is further improved.
