Abstract
A center shaft baffle cover structure used in a single crystal furnace thermal field belongs to the technical field of metallurgy and mechatronics, particularly relates to the center shaft baffle cover structure for baffling leakage liquid from leaking along the center shaft in the single crystal furnace thermal field. The center shaft baffle cover structure used in the single crystal furnace thermal field contains liquid silicon and consists of the center shaft, the center shaft baffle cover and a furnace bottom protection plate; the center shaft baffle cover is rotatably arranged on the center shaft; a lower end of the center shaft is connected with equipment; a furnace bottom protection plate, which is a graphite piece, is arranged on the equipment. The center shaft baffle cover structure used in the single crystal furnace thermal field has the advantages that the liquid silicon can be prevented from leaking along the center shaft to damage the equipment when in operation, damage to single crystal furnace can be reduced, production cost can be lowered, and working efficiency can be improved by the aid of the center shaft baffle cover structure of the thermal field.
Description
Technical field:
Thermal field of single crystal furnace axis material retaining hood structure belongs to the mechanical & electrical technology field that smelts; Be particularly related to the axis material retaining hood structure that thermal field of single crystal furnace stops that leakage is leaked along axis.
Background technology:
Single crystal growing furnace is that polysilicon is converted into the indispensable equipment in the silicon single crystal technological process, and silicon single crystal is the basic material in photovoltaic generation and the semicon industry.Silicon single crystal is as the critical support material of advanced information society, is one of most important monocrystal material in the world at present, and it is not only the major function material of development computingmachine and unicircuit, also is the major function material that photovoltaic generation utilizes sun power.Thermal field of single crystal furnace leaks the silicon liquid that comes out and flows on the equipment along axis in the silicon single-crystal pulling process, damage equipment, and existing thermal field of single crystal furnace does not adopt the axis material retaining hood, causes phenomenons such as SF is low, structure deteriorate easily.
The content of invention:
The utility model thermal field of single crystal furnace axis material retaining hood structure goal of the invention is: manufacture and design a kind of different with prior art, promptly stop leakage along axis leak dismantle again easy to use, the axis material retaining hood structure of being convenient to change.
The utility model thermal field of single crystal furnace axis material retaining hood structure is achieved in that siliceous liquid, is made up of axis, axis material retaining hood and furnace bottom protection plate; Axis material retaining hood spinning is on axis; The lower end of axis is connected with equipment, and the furnace bottom protection plate is a graphite piece, and it is installed on the equipment.
In the silicon single-crystal operation process, the silicon liquid that leakage is come out flows on the furnace bottom protection plate under the effect of axis material retaining hood, and silicon liquid can not flow on the equipment damage equipment along axis.
The beneficial effect of the utility model thermal field of single crystal furnace axis material retaining hood structure is: silicon liquid spills damage equipment along axis when utilizing thermal field axis material retaining hood structure to prevent operation, reduces single crystal growing furnace and damages, and reduces production costs, and improves operating efficiency.
Description of drawings:
Accompanying drawing is a thermal field of single crystal furnace axis material retaining hood structural representation.
Among the figure: silicon liquid 1, axis 2, axis material retaining hood 3, furnace bottom protection plate 4.
Embodiment:
The siliceous liquid 1 of the utility model thermal field of single crystal furnace axis material retaining hood structure is by axis 2, axis material retaining hood 3 and furnace bottom protection plate 4; Axis material retaining hood 3 spinnings are on axis 2; The lower end of axis 2 is connected with equipment, and furnace bottom protection plate 4 is graphite piece, and it is installed on the equipment.
Claims (2)
1. thermal field of single crystal furnace axis material retaining hood structure is characterized in that: siliceous liquid (1), form by axis (2), axis material retaining hood (3) and furnace bottom protection plate (4); Axis material retaining hood (3) is spun on the axis (2); The lower end of axis (2) is connected with equipment.
