The utility model content
Undesirable for solving existing smelting equipment view port effect, influence the problem that infrared thermometer is measured temperature, the utility model provides following technical scheme:
A kind of polysilicon purification furnace viewing window comprises the observation eyeglass and the rotation eyeglass that are installed on the polysilicon purification furnace, and described observation eyeglass is installed on the polysilicon purification furnace by the porthole connecting pipeline, and described rotation eyeglass is connected in the little axle of rotation.
As a kind of preferred version of the present utility model, the both sides up and down of described rotation eyeglass are provided with the wiping groove.
As another kind of preferred version of the present utility model, described wiping groove is a double-side type, and in the described wiping groove high temperature alumina wiping cotton is housed.
As another preferred version of the present utility model, an end of the little axle of described rotation is equipped with handwheel, and described handwheel is positioned at the outside of purification furnace.
As another preferred version of the present utility model, described viewing window is installed in the top of water jacket.
As another preferred version of the present utility model, the part that the little axle of described rotation is connected with purification furnace is equipped with first sealing-ring and second sealing-ring.
The utility model advantage is:
1, the utility model has stoped the pollution of silicon steam to viewing window by the rotation eyeglass, and the rotation eyeglass is cleared up its surperficial pollutent voluntarily by the rotation of rotating little axle, has improved the result of use of viewing window, has reduced the pollution to viewing window;
2, the pollutent of rotation eyeglass can make things convenient for the maintenance of equipment by rotation cleaning voluntarily;
3,, guarantee that vaccum seal ring is not subjected to temperatures involved, thereby guaranteed the excellent sealing of system by the cooling effect of water jacket.
