Technical Field

[0001] The utility model relates to the technical field of polysilicon, in particular to a polysilicon rod transportation device. Background Art

[0002] The existing polysilicon rod production lines all unload the rods, break them into sections, heat them in a high-temperature heating furnace, cool them, break them, and then use a fully automatic packaging line for weighing and packaging. When the rods are broken, they are first heated in a high-temperature heating furnace, then enter an ultrapure water tank for cooling, and then enter the breaking process. During this process, the transportation of the rods is particularly important. The rods are prone to breakage during transportation, and when they are cooled in ultrapure water, pollutants are easily attached to the surface of the rods, causing the surface of the rods to be contaminated.
