The connecting pipe 16 on the shaft of the second inner tube 12 is fixedly connected to the air inlet 17 on the shaft of the outer tube 1.

[0032] A diversion pipe 4 is fixedly installed at the open end of the outer tube 1 chamber.

[0033] The diversion pipe 4 has two independent diversion chambers inside. The two independent diversion chambers of the diversion pipe 4 are independently connected to the first chamber 14 and the second chamber 15, respectively. The top of the diversion pipe 4 has a through hole 19 and a through hole 20, and the two sides of the diversion pipe 4 have a through hole 3 21 and a through hole 4 22, respectively.

[0034] Through hole 19 and through hole 3 21 are connected to the first chamber 15, and through hole 20 and through hole 4 22 are connected to the second chamber 15.

[0035] The shaft of the first inner tube 11, which is away from the first chamber 14, is fixedly connected to the through hole 19, and the shaft of the second inner tube 12, which is away from the second chamber 15, is fixedly connected to the through hole 20.

[0037] A second air outlet pipe 5 is fixedly installed inside the through hole 22, and an air outlet valve 10 is fixedly installed at the lower end of the second air outlet pipe 5.

[0038] The end of the first inner tube 11 furthest from the first chamber 14 is threadedly connected to the first air intake pipe 7, and the lower end of the first air intake pipe 7 is fixedly installed with an air intake valve 9.

[0042] Working principle:

[0043] Before the start of work, the air inlet valve 9 is opened, and hot steam enters the first inner tube 11 and the second inner tube 12 through the first air inlet pipe 7 and the second air inlet pipe 8 respectively. The hot steam enters the hollow layer 24 of the disc 2 through the connecting pipe 16 on the shaft of the first inner tube 11 and the second inner tube 12. The two air inlet pipes increase the flow rate of hot steam per unit time, reduce the waiting time of the disc 2 before entering the drying process, and improve production efficiency.

[0044] As hot steam fills the hollow layer 24, the disc 2 gradually heats up. When the temperature of the disc 2 reaches the temperature required for the drying process, the dryer enters the drying process. At this time, the first air inlet pipe 7 and the second air inlet pipe 8 continuously input hot steam. After the hot steam fills the hollow layer 24, the excess hot steam enters the first chamber 14 and the second chamber 15 through the air outlet 18 on the shaft of the outer pipe 1.

[0045] Hot steam enters the diversion chamber of the diversion pipe 4 along the first chamber 14 and the second chamber 15. The outlet valve 10 is opened, and the hot steam is discharged through the first outlet pipe 6 and the second outlet pipe 5. The two outlet pipes improve the discharge efficiency of the hot steam.
