[0064] The interval between the inlet 101 and the outlet 102 in the main body 10 is the same as the length of the five groups of shelves 12, so that when the mounting rack 31 is full, the shelves 12 between the position of the outlet 102 and the inlet 101 are empty, facilitating the discharge and re-entry of the quartz tube after processing;

[0070] It should be noted that the lower end of the inner cavity of the main body 10 is provided with a limiting ring, and the inner diameter of the limiting ring is smaller than the inner diameter of the lifting pipe 24, so as to limit the movement of the lifting pipe 24, and the lifting pipe 24 cannot be separated from the lower end of the main body 10;
