[0029] The loading, unloading and maintenance of quartz tubes mainly rely on manual operation. Due to the dense longitudinal arrangement of tubes inside the tubular equipment, workers need to carry and lift the quartz tubes to pull them out or load them into the furnace tubes. As the height of the quartz tubes increases, the difficulty of operation and the risk of dropping or damaging the tubes also increase. In addition, if the quartz tubes cause slight cracks during the movement and are not easy to detect, it may affect product quality or cause maintenance rework. In the process of replacing quartz tubes, multiple personnel are required to enter the equipment to perform operations, which not only affects the normal production of other furnace tubes and leads to a decrease in output, but also increases personal safety hazards and labor waste.

The mounting seat 7 is slidably connected to the third guide assembly 6, and the third guide assembly 6 can drive the mounting seat 7 to reciprocate toward the furnace opening 2 of the furnace body, thereby transporting the quartz tube 1 into the furnace body or transporting the quartz tube 1 out of the furnace body. The third guide assembly 6 can be a linear drive motor, a lead screw slide, a cylinder or a hydraulic cylinder, etc., and this application does not limit the third guide assembly 6.

[0034] The mounting seat 7 carries the quartz tube 1.

If it is necessary to transport the quartz tube 1 in the furnace body, and vice versa.

[0036] The present application uses the setting of a feeding device to accurately transport the quartz tube 1 into the furnace body or transport the quartz tube 1 out of the furnace body. Compared with manual operation, this reduces the workload of workers, while improving the transportation accuracy and stability of the quartz tube 1, and also reduces the probability of the quartz tube 1 being damaged during transportation, thereby increasing production.
