Silicon leakage prevention guiding device and single crystal furnace

The utility model discloses a silicon leakage prevention guiding device and a single crystal furnace. The silicon leakage prevention guiding device comprises a bottom wall, a side wall surrounding the bottom wall and a flow guide column arranged on the bottom wall, in the first direction, the side wall is thicker than the bottom wall, and the bottom wall and the side wall define a cavity; the flow guide column is a hollow column body, protrudes out of the bottom wall and penetrates through the bottom wall in the extending direction of the side wall, the sum of the thickness of the flow guide column and the thickness of the bottom wall is smaller than the thickness of the side wall, and the first direction is perpendicular to the direction of the bottom wall. When the silicon liquid leaks, the cavity can contain the leaked silicon liquid, and when a large amount of the silicon liquid leaks, the sum of the thicknesses of the flow guide column and the bottom wall is smaller than the thickness of the side wall, t
