Feeding and discharging device for ingot furnace and ingot furnace

Abstract

The invention provides a feeding and discharging device for an ingot furnace and the ingot furnace adopting the feeding and discharging device. The feeding and discharging device has the advantages ofreasonable structure and convenient operation, a lot of time is saved for an operator to process the operation condition of equipment, therefore, the production efficiency is greatly improved, and the cost is saved. An inclined guide rail is arranged on a base; a moving trolley is arranged on the guide rail; the moving trolley is connected with a left-right moving linear driving device; an ingotfurnace supporting seat is arranged on the moving trolley; a guide rod is arranged at an upper end of the ingot furnace supporting seat; a guide sleeve is arranged on the guide rod; the guide sleeve is arranged on the ingot furnace; a first crank hinged with the moving trolley is arranged on the moving trolley; the other end of the first crank is hinged to a second crank, the other end of the second crank is hinged to the ingot furnace, the moving trolley is further provided with an up-down moving linear driving device hinged to the moving trolley, and an output end of the up-down moving linear driving device moves to drive the ingot furnace to ascend and descend along the guide rod.

Description

technical field [0001] The invention relates to the technical field of ingot furnaces, in particular to a loading and unloading device for an ingot furnace and an ingot furnace. Background technique [0002] Polysilicon ingot furnace is a kind of silicon remelting equipment, the quality of remelting will directly affect the conversion efficiency of silicon wafers and the yield of silicon wafer processing. Due to technical reasons, the domestic polysilicon ingot furnace market has been monopolized by foreign markets. Polysilicon ingot furnace products have always been the bottleneck in the solar polysilicon industry chain. Once the downstream photovoltaic market starts, equipment manufacturers will show explosive growth. [0003] The remelting and crystal growth of silicon raw materials in polycrystalline furnaces requires a stable temperature gradient environment, usually a thermal field. The thermal field in the ingot furnace provides a large amount of heat energy for pol...

AI Technical Summary

Problems solved by technology

However, due to the lack of structural design of the existing polysilicon ingot furnace, the operation process is cumbersome and inconvenient, the invalid operation time is long, and the time utilization rate and production efficiency are low.
