Partitioned electric kiln for producing sintered sand for real stone paint

The utility model relates to a partitioned electric kiln for producing sintered sand for real stone paint, which belongs to the field of partitioned electric kilns and comprises a preheating furnace, a heating furnace, a cooling furnace and a heat conversion device, the preheating furnace is mounted at the upper end of the heating furnace, the cooling furnace is mounted at the lower end of the heating furnace, and the heat conversion device sequentially penetrates through the preheating furnace, the heating furnace and the cooling furnace. The heat conversion device comprises a rotating motor, a rotating shaft, rotating blades, spiral blades, a cooling conversion system and a hand brake, the rotating motor drives the rotating blades to rotate, so that objects in the preheating furnace and the cooling furnace are fully stirred, and the objects in the preheating furnace make contact with the upper-layer heat conduction pipe to be fully heated; the lower-layer heat conduction pipe makes full contact with a high-
