Embodiment
Below in conjunction with drawings and Examples, crucible of the present utility model is helped to be elaborated.
See figures.1.and.2, crucible side 10 for Czochralski method mono-crystal furnace, comprises crucible bowl 11, crucible cylinder 12 and syndeton 13.Crucible cylinder 12 cooperatively interacts with crucible bowl 11.Crucible bowl 11 can be identical or different with the material of crucible cylinder 12, all can be made up of carbon-carbon composite or graphite.
Crucible bowl 11 is roughly dish shape, and it has annular loading end 110.
Crucible cylinder 12 is roughly tubular.Crucible cylinder 12 is carried on the loading end 110 of crucible bowl 11, and with the common receiving space 120 that forms an end opening of crucible bowl 11.Crucible cylinder 12 has 121, one close crucible bowls 11 of two connective slots, and another is away from crucible bowl 11.
Crucible cylinder 12 is enclosed and is formed by cylinder sidewall 122.Cylinder sidewall 122 has relative head end 1220 and tail end 1221.Head end 1220 is connected by syndeton 13 with tail end 1221.Head end 1220 has the first end face 1222, and tail end 1221 has the second end face 1223.Between the first end face 1222 and the second end face 1223, there is gap 124.The width in gap 124 is 0.1 millimeter to 3 millimeters.Cylinder sidewall 122 also has relative end face 1224 and bottom surface 1225, and end face 1224 and bottom surface 1225 are all connected between head end 1220 and tail end 1221.Bottom surface 1225 contacts with the loading end 110 of crucible bowl 11, and end face 1224 is away from crucible bowl 11.Head end 1220 has 1226, one of two the first storage tanks away from crucible bowl 11 and is opened in the first end face 1222 and end face 1224 junctions, and one near crucible bowl 11 and be opened in the first end face 1222 and 1225 junctions, bottom surface.Tail end 1221 has two the second storage tanks 1227.One away from crucible bowl 11 and be opened in the second end face 1223 and end face 1224 junctions, and one near crucible bowl 11 and be opened in the second end face 1223 and 1225 junctions, bottom surface.Each the first storage tank 1226 is all roughly " L " type, comprises the first holding part 1228 and the second holding part 1229 that are connected.Wherein, the first holding part 1228 is near the first end face 1222, and the first holding part 1228 is less than the degree of depth of the second holding part 1229 along the degree of depth of crucible cylinder 12 short transverses.Each the second storage tank 1227 is all roughly " L " type, comprises the 3rd holding part 1230 and the 4th holding part 1231 that are connected.Wherein, the 3rd holding part 1230 is near the second end face 1223, and the 3rd holding part 1230 is less than the degree of depth of the 4th holding part 1231 along the degree of depth of crucible cylinder 12 short transverses.The degree of depth of the 3rd holding part 1230 is identical with the degree of depth of the first holding part 1228.In the present embodiment, the second holding part 1229 is also identical with the degree of depth of the 4th holding part 1231.Thus, all corresponding with one the second storage tank 1227 is common forms a connective slot 121 that is roughly " U " type for each the first storage tank 1226.
Head end 1220 also have with two the first storage tanks 1226 one by one 1232, one of two first pickup grooves of corresponding connection away from 11, one, crucible bowl near crucible bowls 11.Each the first pickup groove 1232 all from the second holding part 1229 of the first storage tank 1226 to offering away from the direction of the first end face 1222.Each the first pickup groove 1232 also inwardly offers the first fixed orifices 1233 along the short transverse of crucible cylinder 12.Tail end 1221 also have with two the second storage tanks 1227 one by one 1234, one of two second pickup grooves of corresponding connection away from 11, one, crucible bowl near crucible bowls 11.Each the second pickup groove 1234 all from the 4th holding part 1231 of the second storage tank 1227 to offering away from the direction of the second end face 1223.Each the second pickup groove 1234 also inwardly offers the second fixed orifices 1235 along the short transverse of crucible cylinder 12.
Referring to Fig. 3, the head end 1220 of syndeton 13 connecting cylinder sidewalls 122 and tail end 1221.Syndeton 13 comprises two linkers 130 and multiple mounting block 131.Linker 130 and mounting block 131 can be carbon-carbon composite or metal molybdenum material, or other can be used for the material of thermal field.Two linkers 130 are corresponding one by one with two connective slots 121, and each linker 130 is all fixed in a corresponding connective slot 121 by least one mounting block 131, thereby connect head end 1220 and tail end 1221.The shape of the shape of linker 130 and connective slot 121 matches.Be placed in connective slot 121 when interior away from the linker 130 of crucible bowl 11, the upper surface of linker 130 is lower than the end face 1224 of crucible cylinder 12, or concordant with end face 1224.In the present embodiment, the upper surface of linker 130 is basic concordant with end face 1224.Be placed in connective slot 121 near the linker 130 of crucible bowl 11, the upper surface of linker 130 is lower than the bottom surface 1225 of crucible cylinder 12, or concordant with bottom surface 1225.In the present embodiment, the upper surface of linker 130 is basic concordant with end face 1224, and is carried on the loading end 110 of crucible bowl 11.Linker 130 is also " U " type structure, and it comprises the first arm 132, the second arm 133 and connecting arm 134, and connecting arm 134 is connected between the first arm 132 and the second arm 133.Particularly, the second holding part 1229, the second arms 133 that the first arm 132 is placed in connective slot 121 are placed in the 4th holding part 1231 of connective slot 121, and connecting arm 134 is placed in the first holding part 1228 and the 3rd holding part 1230.The first arm 132 offers the 3rd pickup groove 1320, the three pickup grooves 1320 and first fixed part 1321 of the first pickup groove 1232 common formations with connecting arm 134 junctions.The 3rd pickup groove 1320 also inwardly offers the 3rd fixed orifices 1322 along the short transverse of crucible cylinder 12.The second arm 133 offers the 4th pickup groove 1330, the four pickup grooves 1330 and second fixed part 1331 of the second pickup groove 1234 common formations with connecting arm 134 junctions.The 4th pickup groove 1330 also inwardly offers the 4th fixed orifices 1332 along the short transverse of crucible cylinder 12.Mounting block 131 is also " U " type structure.Away from crucible bowl 11 places, adopt two mounting blocks 131 that linker 130 is fixed on to 121: one mounting blocks 131 of connective slot and be placed in the first fixed part 1321, one end of mounting block 131 is inserted in the first fixed orifices 1233 of head end 1220, the other end inserts in the 3rd fixed orifices 1322 of linker 130, thereby the first arm 132 of linker 130 is fixed on to head end 1220; Another mounting block 131 is placed in the second fixed part 1331, one end of mounting block 131 is inserted in the second fixed orifices 1235 of tail end 1221, the other end inserts in the 4th fixed orifices 1332 of linker 130, thereby the second arm 133 of linker 130 is fixed on to tail end 1221.Near crucible bowl 11 places, also use that two mounting blocks 131 are fixed on head end 1220 by the first arm 132 of linker 130 respectively, the second arm 133 is fixed on tail end 1221.Certainly, mounting block 131 also can be other structure, only needs the first arm 132 of linker 130 and the second arm 133 to be individually fixed in head end 1220 and tail end 1221.
Crucible of the present utility model side 10 has gap 124, and crystal pulling completes takes off syndeton 13 and take crucible apart and help at 10 o'clock, and gap 124 becomes large, can from crucible side 10, take out quartz crucible easily, extends the work-ing life of crucible side 10.In addition, when syndeton 13 connects head end 1220 and tail end 1221, the first arm 132 of linker 130 is fixed on head end 1220, the second arm 133 is fixed on tail end 1221, both can in the situation that not increase crucible and helping 10 thickness, realize and connecting, and can avoid again linker 130 to fall in crucible side 10 or outside crucible side 10.
The utility model provides a kind of crucible side of being convenient to take out quartz crucible and long service life, has solved existing crucible and has helped short problem of inconvenient dismounting, work-ing life.
