Abstract

本实用新型涉及一种单晶直拉工艺中用保温筒,该保温筒的筒沿位于筒身的上部,筒沿向筒身内侧伸出,凸出筒身,采用本实用新型,增强了操作工抓手用力的便利性,提高了操作安全性。

Description

一种单晶直拉工艺中用保温筒
技术领域
本实用新型涉及一种单晶直拉工艺中用保温筒。
背景技术
在单晶直拉工艺中,当晶棒拉制完毕后,需取出单晶炉内的保温筒。通常情况下,由二位操作工戴着耐高温手套,一起直接用手抓持保温筒将其抬出单晶炉。但是,因筒沿与筒身一样厚薄,不方便抓手用力,易失手打破保温筒,给企业造成损失,出现生产事故。
发明内容
本实用新型的目的是提供能防止出现生产事故的一种单晶直拉工艺中用保温筒。
本实用新型采取的技术方案是:一种单晶直拉工艺中用保温筒,包括筒沿与筒身,筒沿位于筒身的上部,其特征在于筒沿向筒身内侧伸出,凸出筒身。
采用本实用新型,增强了操作工抓手用力的便利性,提高了操作安全性。
附图说明
图1是本实用新型的示意图。
图中序号表示:筒身1、筒沿2
具体实施方式
下面对本实用新型作进一步说明。
参照图1,该单晶直拉工艺中用保温筒包括筒沿2与筒身1,筒沿2位于筒身1的上部,筒沿2向筒身1的内侧伸出,凸出筒身1,即筒沿2的内径小于筒身1的内径。使用时,由操作工抓住筒沿2的凸出部,即可方便用力,防止失手打破保温筒,提高了生产安全性。
