The combined type copple that described volume is adjustable is on the cavity in crucible, the inside face of additional tube A is respectively equipped with the barium coating.

The combined type copple that described volume is adjustable, the barium coat-thickness on the described crucible inner chamber body, on the additional tube A inside face is 1～2mm.

The combined type copple that described volume is adjustable, the described annular recess that is arranged on the crucible upper edge is " U " shape groove or " V " shape groove; The protruding ring that is arranged on additional tube A lower surface is " U " shape projection or " V " shape projection.

The combined type copple that described volume is adjustable is provided with additional tube B between crucible and additional tube A, be respectively equipped with annular recess, protruding ring on the tube upper edge of described additional tube B and the lower surface.

The combined type copple that described volume is adjustable, the described annular recess that is arranged on additional tube B tube upper edge is " U " shape groove or " V " shape groove; The protruding ring that is arranged on additional tube B lower surface is " U " shape projection or " V " shape projection.

The combined type copple that described volume is adjustable is provided with the barium coating in the inside face of adding tube B.

The combined type copple that described volume is adjustable, the barium coat-thickness that arranges on the additional tube B inside face is 1～2mm.

By above-mentioned disclosure, the beneficial effects of the utility model are:

The combined type copple that volume described in the utility model is adjustable, by crucible being divided into crucible and additional tube A, also can increase additional tube B, in use by adding the combination of tube A, additional tube B and crucible, realized that fragile part can independently change, permanent partial can repeatedly use, and the utility model people is through test, the time limit of service of additional tube A, additional tube B is more than 20 times of crucible, and guaranteed performance can not reduce; The utility model makes the crucible bottom of damaging easily in time change, and the intact part in top is repeatedly used, though slightly improve with respect to prior art the utility model tooling cost, use cost has obtained significantly reducing, and stability is higher when melting crystal; The material that the utility model crucible uses is quartz sand, in view of mixing of quartz sand composition and silicon single crystal or polysilicon at high temperature appears in quartz sand easily, make to occur unnecessary composition in silicon single crystal or the polysilicon that the barium coating that the utility model arranges at crucible, additional tube A and additional tube B can be guaranteed the quality of silicon single crystal.
