Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon manufacturing equipment, in particular to a re-investment stabilization device and a feeding component. Background Art

[0002] In the existing single crystal pulling process, in order to reduce production costs and maximize the utilization rate of quartz crucibles, multiple single crystals are pulled in a single furnace by re-feeding silicon materials. In the re-feeding process, the process from hanging the re-feeding bucket filled with silicon materials into the single crystal furnace to taking out the re-feeding bucket from the single crystal furnace is mainly manually operated by the re-feeding device. In this process, the operator needs to connect the re-feeding device with the re-feeding hook and manually stabilize the re-feeding device to avoid abnormal accidents caused by the upper edge of the re-feeding device and the lower edge of the auxiliary chamber. It is not until the upper edge of the re-feeding device enters the lower edge of the auxiliary chamber that it can be automatically connected with the next process step; it is time-consuming and labor-intensive. At the same time, due to the different skills of the operators, the re-feeding time is not uniform. The single crystal furnace needs to be repeatedly unhooked and hung before and after charging. Due to problems such as the re-throwing vehicle and the base cover, the re-throwing hook is usually in a tilted state when the re-throwing device is unhooked and hung. It is easy to cause the hard heavy hammer pull rope (such as tungsten wire rope) to bend when unhooking, resulting in the seed crystal shaking during the crystal pulling process, abnormal crystal rods being pulled out, or even the inability to pull out the crystal rod; the silicon powder remaining in the re-throwing device will be scattered on the inner wall of the sub-chamber, and the cylinder wall needs to be wiped manually.
