Description
Technical field
The utility model relates to typing charcoal fiber heat preservation material production technical field, refers in particular to a kind of device that adopts the indirect heating mode that the single crystal growing furnace heat-preservation cylinder is heated and is rotated simultaneously.
Background technology
The typing charcoal fiber heat preservation material is as charcoal fiber-like lagging material, and one of Main Function is to provide insulation support for crystalline silicon production unit high temperature thermal field system at present.
The thermal field of monocrystalline silicon draw machines all is the garden tubular at present, thereby the heat-insulation system that requires to match also is tubular.For adopting slim charcoal felt or the bonding moulding process that rolls into the cartridge type workpiece of graphite felt lamination, when adopting the thermosetting resin caking agent to carry out bonding solidifying and setting, just need to heat and to solidify workpiece.The thermosetting resin caking agent that generally adopts at present, solidifying Heating temperature often needs to reach about 100-200 ℃, and that have even higher, set time is also long.And the caking agent when not yet solidifying also has certain flowability, under static state since the action of gravitation caking agent can assemble to the below that workpiece is placed.Therefore need rotating mold ceaselessly and on workpiece, otherwise cause workpiece density irregularity everywhere because of the skewness of caking agent after solidifying, easily cause local deformaton even cracking, directly quality product is exerted an influence.Therefore, need the mode of the heating while rotating to satisfy such processing requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the typing of processing easily and effectively charcoal fiber heat preservation material cartridge type workpiece to use, and from the outside workpiece is heated and the device of rotation simultaneously.
For achieving the above object, technical scheme provided by the utility model is: a kind of rotatable heater for the single crystal growing furnace heat-preservation cylinder, it comprises frame and rack-mounted casing, described casing is made of lower insulation can and the upper insulation can that is hinged on the lower insulation can, an axis hole is respectively established in the junction at upper and lower insulation can two ends, the reel mould is positioned at casing, and the driving sleeve of reel both mold ends is contained on the axis hole, and wherein the transmission shaft of an end stretches out that casing is outer to be connected with power wheel; Be provided with electric heater in the lower insulation can of reel mould below; Upper insulation can top one side is provided with upwardly extending vapor pipe, and upper insulation can top opposite side is provided with thermopair.
Described electric heater is two or more, all is positioned at lower insulation can.
Described power wheel is connected with the reduction box that is installed in frame one side, and the output terminal of reduction box is connected with power wheel on the mould by belt or chain wheel, and the input terminus of reduction box is connected with motor.
Described frame adopts angle steel to be welded.
The inner side-wall of described upper and lower insulation can is covered with insulation quilt.
The utility model is after having adopted such scheme, be positioned in the lump on the axis hole with having applied the single crystal growing furnace heat-preservation cylinder that caking agent and reel finish together with the reel mould, power wheel is connected with reduction box, start motor and make the mould rotation, open again electric heater, set the temperature and time that needs control, the sealed thermal insulating case can heat workpiece; This device is simple and practical, and cost is not high, can satisfy the needs of above-mentioned production technique.
