Abstract
The utility model relates to a feeder for a single crystal furnace. A fixing bracket is mounted on a barrel body; a telescopic rod is movably arranged on the fixing bracket; a conical body is positioned at the lower part of the barrel body and connected with one end of the telescopic rod; a sleeve pipe is fixedly mounted on the fixing bracket; a clamping hole is formed in the sleeve pipe; a spring buckle is arranged on the telescopic rod; the telescopic rod is movably arranged in the sleeve pipe. By adopting the feeder, the spring buckle can be clamped through the clamping hole in the sleeve pipe during a feeding process, a feeding device can be safely taken out once being jammed by silicon materials, and the phenomenon of a dilemma cannot be caused.
Description
Technical field
The utility model relates to a kind of single crystal growing furnace feeder.
Background technology
The single crystal growing furnace feeder using at present, by being located at the expansion link on the fixed support on cylindrical shell top, open after the cone of bottom, just start to add silicon material, the hidden danger that this device exists is sometimes to exist the phenomenon of advance and retreat two difficulties, if silicon material is excessive or fall too fast, silicon material can stop up between cone and cylindrical shell, cause expansion link bias to block, and now upwards take out feeding device, once there is again reinforced phenomenon, silicon material can drop on single crystal growing furnace from eminence, cause the silicon material of fusing in single crystal growing furnace splash or smash single crystal growing furnace, to bring immeasurable loss to production.
Summary of the invention
The purpose of this utility model is to provide can be at a kind of single crystal growing furnace feeder that occurs can take out safely when silicon material stops up.
The technical scheme that the utility model is taked is: a kind of single crystal growing furnace feeder, fixed support is arranged on cylindrical shell, expansion link is actively installed on fixed support, cone is positioned at cylindrical shell bottom and is connected with one end of expansion link, it is characterized in that being installed with sleeve pipe on fixed support, on sleeve pipe, have bayonet socket, expansion link is provided with spring fastener, and expansion link is movably arranged in sleeve pipe.
Adopt the utility model, can when reinforced, by the bayonet socket on sleeve pipe, block spring fastener, once silicon material, stop up and can take out safely feeding device, and the phenomenon generation of two difficulties that can not cause advancing and retreat.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure, sequence number represents: sleeve pipe 1, spring fastener 2, expansion link 3, bayonet socket 4, cylindrical shell 5, cone 6 and fixed support 7.
Embodiment
Below the utility model is described in further detail.
With reference to Fig. 1, this single crystal growing furnace is arranged on the upper of cylindrical shell 5 with the fixed support 7 of feeder, expansion link 3 is actively installed on fixed support 7, cone 6 is positioned at cylindrical shell 5 bottoms and is connected with one end of expansion link 3, on fixed support 7, be installed with sleeve pipe 1, on sleeve pipe 1, have bayonet socket 4, expansion link 3 is provided with spring fastener 2, and expansion link 3 is movably arranged in sleeve pipe 1.During use, when opening cone 6 by the downward activity of expansion link 3 when reinforced, spring fastener 2 enters bayonet socket 4 and blocks that to make expansion link 3 remain on fixed position motionless, if when silicon material occurring stopping up, silicon material can not drop out from feeding device, just can take out safely feeding device.
