Abstract
The utility model provides a heat-preservation barrel hoisting device in a thermal field of a single crystal furnace, belonging to the field of a smelting electromechanical technology and particularly relating to a device for safely hoisting a heat-preservation barrel in the thermal field of the single crystal furnace. The heat-preservation barrel hoisting device consists of a middle furnace body, a middle heat-preservation quilt, a middle heat-preservation barrel, a supporting block and a supporting ring. The supporting ring is an annular plate and is mounted by means of being concentric with the middle heat-preservation barrel; a lower plane is mounted on the supporting block; an upper plane is provided with the middle heat-preservation barrel and the middle heat-preservation quilt; the middle heat-preservation quilt is coated at the outer side of the middle heat-preservation barrel; the supporting block is fixed on the middle furnace body in a concentric manner; and the middle heat-preservation quilt 2 is a graphite carbon quilt piece. The heat-preservation barrel hoisting device provided by the utility model has the beneficial effects as follows: no supporting points exist in the middle heat-preservation barrel and the middle heat-preservation quilt in a process of drawing the single crystal furnace; potential safety hazards, such as easiness of dropping and damage, can be solved; the cost is reduced; the working efficiency is improved; and the heat-preservation barrel hoisting device is convenient to dismantle and use and is convenient to replace.
Description
Technical field:
The insulated tank lifting gear belongs to the mechanical & electrical technology field that smelts in the thermal field of single crystal furnace; Be particularly related to the device of insulated tank in the thermal field of single crystal furnace security improvement.
Background technology:
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; 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.Single crystal growing furnace utilizes insulated tank lifting gear in the stove thermal field after silicon single-crystal draws completion, can reduce the take-down time of thermal field, reduces the damage of thermal field graphite piece when dismounting.But insulated tank lifting gear in the present thermal field of single crystal furnace, the structure imperfection, middle insulated tank and middle insulation quilt are installed and used and are had hidden danger, cause the thermal field graphite piece to damage, influence phenomenons such as equipment operation easily.
The content of invention:
Insulated tank lifting gear goal of the invention is in the utility model thermal field of single crystal furnace: solve the single crystal growing furnace crystal and draw security hidden trouble, manufacture and design insulated tank lifting gear in a kind of thermal field of single crystal furnace different with prior art.
The insulated tank lifting gear is achieved in that by middle body of heater, middle insulation quilt, middle insulated tank, back-up block and support ring and forms in the utility model thermal field of single crystal furnace; Support ring is that annular plate and middle insulated tank concentric are installed, and lower plane is installed on the back-up block, and last Plane Installation has middle insulated tank and middle insulation quilt, insulation quilt in the outside parcel of middle insulated tank; The back-up block concentric is fixed on the middle body of heater; Middle insulation quilt 2 is a graphite carbon felt spare.
During the silicon single-crystal operation process, along with middle body of heater rises, under the effect of back-up block, support ring and middle insulation quilt, middle insulated tank rise together.
The beneficial effect of insulated tank lifting gear is in the utility model thermal field of single crystal furnace: insulated tank and middle insulation quilt do not have point of suppon in having solved in the drawing of single crystal growing furnace crystal, are prone to the security hidden trouble that drops and damage; Reduce cost, improved operating efficiency; Dismantle easy to usely, be convenient to change.
Description of drawings:
Accompanying drawing is an insulated tank lifting gear structural representation in the thermal field of single crystal furnace.
Among the figure: middle body of heater 1, middle insulation quilt 2, middle insulated tank 3, back-up block 4, support ring 5.
Embodiment:
The insulated tank lifting gear is made up of middle body of heater 1, middle insulation quilt 2, middle insulated tank 3, back-up block 4 and support ring 5 in the utility model thermal field of single crystal furnace; Support ring 5 is annular plate and middle insulated tank 3 suits, and lower plane is installed on the back-up block 4, and last Plane Installation has middle insulated tank 3 and middle insulation quilt 2, insulation quilt 2 in the outside parcel of middle insulated tank 3; Back-up block 4 concentrics are fixed on the middle body of heater 1; Middle insulation quilt 2 is a graphite carbon felt spare.
