Movable discharge polysilicon ingot furnace

The utility model relates to a movable discharge polysilicon ingot furnace, which comprises a furnace standing support and an upper furnace cavity suspended on the platform of the furnace standing support. A liftable lower furnace cavity controlled by a lifting mechanism is arranged under the upper furnace cavity. The two furnace cavities are tightly closed and fixed by a fixing device when the lifting mechanism is lifted in position. A guiding track protruding out of the furnace standing support is arranged under the ingot furnace. The guiding track is provided with a sliding block which is used for supporting the lower furnace cavity and capable of reciprocating along the guiding track under traction of a transmission mechanism. When ingots are finished and discharged, the lower furnace cavity is lowered on the sliding block on the guiding track by the lifting mechanism, slides out along the guiding track from a place under the furnace through traction of the sliding block, and the polisilicon ingots and th
