The lifting mechanism is reasonable in structure, the crucible platform can move up and down in the thermal insulator of the ingot furnace, and the technical requirement needed by the production of the pseudo-single crystal ingot furnace can be met.
Description
Technical field
The utility model belongs to accurate single-crystal ingot casting furnace technical field, particularly lower well heater hoisting appliance in ingot furnace.
Background technology
Accurate monocrystalline is the mode of casting crystalline that adopts on polycrystalline silicon ingot or purifying furnace, the quasi-monocrystalline silicon with high-conversion rate of producing through a series of advanced persons' technical process.Its main technique is to place seed crystal by the bottom at the polycrystalline silicon ingot or purifying furnace quartz crucible, and under vacuum state, adopts accurately sectional temperature-controlledly, and while guaranteeing the thawing of silicon material, the seed crystal partial melting, grow monocrystalline thus.Domestic polycrystalline silicon ingot or purifying furnace is mainly that crucible, platform are motionless at present, and upper heating element, side heating element and upper thermal insulator move up and down.This structure can meet processing requirement to polycrystalline silicon ingot or purifying furnace, but, because former polycrystalline silicon ingot or purifying furnace does not descend heating element, in the ingot furnace of producing quasi-monocrystalline silicon, just can not meet processing requirement.In order to meet the requirement of quasi-monocrystalline silicon ingot casting, ingot furnace must have strict thermograde and setting rate to control, and applicable interface shape, therefore need to arrange a lower well heater that can move up and down.
The utility model content
The purpose of this utility model is to provide a kind of lower heater mechanism moved up and down, and produce needed processing requirement to meet the quasi-monocrystalline silicon ingot casting: solid-liquid interface forms within the shortest time.
For achieving the above object, the utility model adopts following scheme:
A kind of lower well heater hoisting appliance of accurate single-crystal ingot casting furnace, comprise lower heating element, mounting block, electrode mast, retaining plate, cushion block, supporting plate, lifting device, driving snake and motor.
Described lower heating element is arranged on the crucible platform bottom surface of thermal insulator inside by mounting block, lower heating element is equipped with vertically disposed electrode mast, electrode mast is arranged on retaining plate after stretching out thermal insulator and body of heater downwards, and retaining plate is connected with supporting plate by insulating pad; Be fixed with lifting device under body of heater, lifting device is connected with supporting plate; Supporting plate is provided with driving snake and motor, and lifting device is connected and driven by driving snake, and driving snake is connected and driven by motor.
The utility model is rational in infrastructure, and lower heating element can be moved up and down in the ingot furnace thermal insulator, has met the quasi-monocrystalline silicon ingot casting and has produced needed processing requirement.
