Description

Technical Field

[0001] The utility model belongs to the technical field related to photovoltaics and semiconductors, and particularly relates to a barrel lifting rod. Background Art

[0002] Currently, the barrel lifting rods in the industry are mostly made of metal, with a quartz glass isolation tube on the outer wall. During the feeding process, the quartz isolation tube has a short service life and relatively high application cost. Furthermore, during the feeding process, the metal rod often melts, resulting in metal contamination of the entire crucible of raw materials, making it impossible to reuse, resulting in significant losses. The present invention can be used in the feeding barrel lifting device of the photovoltaic and semiconductor crystal pulling industries. The lifting rods of this design are spliced from silicon carbide, which can avoid the metal contamination of the raw materials caused by the melting of the metal rod, making them impossible to reuse. At the same time, it can eliminate the existing metal isolation device outside the lifting rod, saving costs. Utility Model Content
