Abstract
The utility model relates to the field of crystalline silicon growth, in particular to a polycrystalline silicon ingot casting furnace. A lower furnace body lifting device of the polycrystalline silicon ingot casting furnace comprises three driving boxes, three worm wheel worm lifting machines and a driving motor. The driving motor is connected with any one driving box through a transmission mechanism, the three driving boxes are integrated with a flexible shaft through a coupling, the input ends of the worm wheel worm lifting machines are installed on the driving boxes in one-to-one corresponding mode, and the output ends of the worm wheel worm lifting machines are connected with the lower furnace body. Due to a fact that the three worm wheel worm lifting machines are connected through the flexible shaft and driven by the driving motor, synchronized linkage is realized, thereby guaranteeing levelness of the lower furnace body in lifting, enabling the lower furnace body to be more stable in lifting and not easy to damage, and improving stability of inner hot field of a furnace body.
Description
Technical field
The utility model relates to crystalline silicon growth field, relates in particular to a kind of polycrystalline silicon ingot or purifying furnace.
Background technology
Polycrystalline silicon ingot or purifying furnace is the important production unit of used silicon single crystal in the production solar energy power generating field.This equipment with the polysilicon shivering material, materials such as the useless sheet of material, pot bottom material, various monocrystalline are packed in the quartz crucible of stove internalization material end to end, through melting, redirecting technologies such as crystallization and annealing, cast preceding road raw material----the polysilicon silicon ingot of producing solar cell.
During polycrystalline silicon ingot or purifying furnace work, before ingot casting, utilize hoisting appliance that lower furnace body is descended earlier, open furnace chamber, the crucible that installs the silicon material is sent in the stove, then, hoisting appliance drives lower furnace body again and rises, and closes furnace chamber, carries out the ingot casting operation; After the ingot casting operation finished, lower furnace body descended, and opens furnace chamber, took out the good silicon ingot of casting.Lower furnace body hoisting appliance in the existing polycrystalline silicon ingot or purifying furnace overlaps independently by three that lifting motor constitutes, and three lifting motors connect three points of lower furnace body respectively, drive the lower furnace body lifting, are difficult to guarantee synchronous working, lifting process instability.
Summary of the invention
