[0026] In the embodiment, the silicon mud to be dried is transported into the first rotary cylinder 4 through the feeding hopper 5, and the silicon mud is moved from one end of the feeding hopper 5 to the discharging mechanism under the cooperation of the helical blade 6 during the rotation of the first rotary cylinder 4.

The flue gas generated by the combustion is discharged from the exhaust passage 3 to the outside of the combustion chamber 1. The silicon mud drying system of the embodiment can realize continuous drying operation of the silicon mud, and due to the cooperation of the rotation of the first rotary cylinder 4 and the helical blade 6, the silicon mud can be uniformly heated during the drying process, which improves the drying efficiency and avoids the problem of uneven drying.

[0027] In the embodiment, the fuel of the combustion machine is combustible gas, and the combustion chamber 1 is further provided with a heat recovery pipeline 7, one end of the heat recovery pipeline 7 is in communication with the inner cavity of the combustion chamber 1, and the other end of the heat recovery pipeline 7 is arranged at the position close to the fuel delivery pipeline of the combustion machine for preheating the combustion air in the fuel delivery pipeline. Through the arrangement of the heat recovery pipeline 7, the heat energy in the high-temperature flue gas generated in the combustion chamber 1 can be fully utilized to preheat the combustion air about to enter the combustion machine, thereby increasing the temperature of the fuel gas and enabling the fuel gas to burn more fully during the combustion process, which improves the combustion efficiency and reduces the waste of energy.
[0028] In the embodiment, the feeding hopper 5 and the first rotary cylinder 4 are further provided with a crushing mechanism 8 for crushing the materials in the feeding hopper 5 and then inputting the materials into the first rotary cylinder 4.
