一种破碎多晶硅棒的装置及方法
摘要：
本发明涉及一种多晶硅棒破碎装置及方法，其中多晶硅棒破碎装置包括密封容器和向所述密封容器通入压缩气体的供气装置，所述密封容器设有压缩气体入口和出气门，所述供气装置通过所述压缩气体入口向所述密封容器通入压缩气体。本发明提供的多晶硅棒破碎装置及方法将压缩气体压入多晶硅棒的空隙内，然后瞬间减压，使多晶硅棒空隙内的气体迅速向外流动，使多晶硅棒“爆炸”成为碎块。本发明所述的破碎多晶硅棒的方法和装置结构简单、成本低，克服了现有的多晶硅棒破碎装置及方法效率低、成本高的缺点，提供一种成本低、效率高，且不会对硅原料产生污染的多晶硅棒破碎装置及方法。
摘要（英）：

The present invention relates to a device and a method for breaking a polycrystalline silicon rod. The device for breaking a polycrystalline silicon rod comprises a sealing container and a gas supply device used for leading compressed gas into the sealing container, wherein the sealing container is provided with a compressed gas inlet and a gas outlet valve, and the gas supply device is used for leading compressed gas into the sealing container through the compressed gas inlet. In the device and the method for breaking a polycrystalline silicon rod, the compressed gas is compressed into a gap of a polycrystalline silicon rod, and then the pressure is instantaneously reduced to ensure that gas in the gap of the polycrystalline silicon rod quickly outwards flows, and the polycrystalline silicon rodis exploded into fragments. The method and the device for breaking the polycrystalline silicon rod have the advantages of simple structure and low cost, overcomes the defects of low efficiency and high cost of the traditional device and method for breaking the polycrystalline silicon rod and has low cost, high efficiency and no pollution to silicon raw materials.
