At the same time, the heating area of ​​the sintering chamber by the igniter is relatively fixed, and the hot gas generated during sintering is directly discharged, and the heat of the hot gas cannot be reused. Utility Model Content

The hollow stirring rod with a serpentine structure can not only stir the expanded clay, but also increase the contact area between itself and the expanded clay, thereby heating the expanded clay from the inside in conjunction with the transportation of hot air.

[0010] Preferably, a fixed rod is fixedly connected to the inside of the sintering inner chamber, and the fixed rod is used in conjunction with a hollow stirring rod. When the hollow stirring rod rotates, the ceramsite can be stirred.

Since the sintering inner chamber 2 itself is also rotating, the heating area of ​​the sintering inner chamber 2 by the igniter 12 is more uniform and comprehensive. Combined with the stirring of the ceramsite in two directions by the hollow stirring rod 3 and the fixed rod 15, the ceramsite is heated more evenly. At the same time, the hot air generated during sintering will be transported to the inside of the hollow stirring rod 3 through the fourth conveying pipe 13 and the pneumatic rotary joint 14, so that the hollow stirring rod 3 can stir the ceramsite and further heat the ceramsite from the inside, thereby achieving the purpose of recycling and reusing the heat of the hot air.
