The utility model relates to an internal circulation level retort which can distill oil residues from oil-contained solid. The internal circulation level retort comprises an inner cylinder (4), a large gear (5) and a hot blast intake device (10), etc.; wherein, the inner cylinder (4) stretches out through a smoke and residue discharge cover (3), the end face of the stretched part of the inner cylinder (4) is provided with a feeder (6), build-in spiral passages (13) are arranged in the inner cylinder (4), a residue gatherer (15) is arranged at the middle part of the inner cylinder (4), an outer circle of spiral vanes (19) and a wearable supplementary plate (24) are welded on the inner surface of the inner cylinder (4); hanging chains (18) are welded at the feeding end of the inner cylinder (4), therefore, the heat of distilled and burnt high temperature residue of materials can be utilized effectively, the distill is speeded up and the cylinder structure at the distillation area between two build-in spiral passages in the inner cylinder is shortened; the wearable supplementary plate for preventing wear on the cylinder and the hanging chains for preventing material sticking are arranged, thus improving the wear resistance performance of the device and the heat efficiency of the system and the production capacity of the device.
