Abstract
A single crystal furnace thermal field with a support ring belongs to the field of a smelting dynamo-electric technology, and specially relates to an elevating system of the single crystal furnace thermal field with a support ring. Thermal field parts are arranged in the cavity between the inner and outer cylinders of a middle boiler body and in the cavity between the inner and outer cylinders of a lower boiler body; the support ring is a graphite member, the lower end surface of the support ring is supported by a support block, and the support block is fixedly arranged on the lower flange of the middle boiler body through a screw; and the middle boiler body and the lower boiler body are water-cooled welding members, comprising upper and lower flanges, inner and outer cylinders and middle water channels, and the middle boiler body and the lower boiler body are concentrically arranged. The beneficial effects are provided as following: loss is reduced, the work efficiency is raised, dismounting usage is convenient, and the phenomenon of high working strength and difficult maintenance of the prior mechanism is thoroughly solved.
Description
Technical field
Thermal field of single crystal furnace with support ring belongs to smelting mechanical ﹠ electrical technology field, the particularly hoisting appliance of single crystal silicon thermal field band support ring.
Background technology
Single crystal growing furnace is that polysilicon is converted into the necessary 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 present one of most important monocrystal material in the world, and it is not only the major function material of development computer and unicircuit, also is the major function material that photovoltaic generation utilizes sun power; General thermal field of single crystal furnace does not adopt support ring, very easily causes the phenomenons such as dismounting thermal field part fatigue, thermal field damage parts.
Summary of the invention
The thermal field of single crystal furnace goal of the invention of the utility model band support ring is: manufacture and design that a kind of safety coefficient unlike the prior art is high, operation is easily with the thermal field of single crystal furnace of support ring.
The thermal field of single crystal furnace of the utility model band support ring is achieved in that by thermal field part, middle body of heater, support ring, back-up block and lower furnace body and forms; The thermal field part is installed in the cavity between the inside and outside cylindrical shell of middle body of heater and lower furnace body; Support ring is graphite piece, and its lower surface is supported by back-up block, and back-up block is fixed by screws on the lower flange of middle body of heater; Middle body of heater and lower furnace body are the Water-cooling Welding fitting, are made of upper lower flange, inside and outside cylindrical shell and internal water main, and concentric is installed; The thermal field part is comprised of graphite piece and insulation quilt; Back-up block is made by the SUS316 material.
After silicon single-crystal finished crystal pulling, under the effect of middle hoisting appliance, middle body of heater rose, and drove back-up block and support ring and rose together, and the thermal field part rises under the supporting role of support ring together, thereby reduced the workload of dismounting thermal field.
The beneficial effect of the thermal field of single crystal furnace of the utility model band support ring is: reduce the wastage, improve operating efficiency; Dismantle easy to usely, thoroughly solved the phenomenons such as working strength that former mechanism exists is large, difficult in maintenance.
