The partition plate 12 guides the high-temperature gas to enter the upside air chamber from the surroundings of the drying cylinder 11 or the inside of the drying cylinder 11. Before the two air chambers are separated, the airflow will encounter great resistance when passing through the drying cylinder 11, resulting in most of the airflow flowing from the upstream of both sides of the drying cylinder 11 and failing to effectively exchange heat with the broken manganese and washed manganese. Therefore, the partition plate 12 is added, and the number of partition plates 12 can be multiple. The purpose is to limit the airflow from flowing from the upstream of both sides of the drying cylinder 11. After improvement, most of the high-temperature airflow will enter the inside of the drying cylinder 11 through the mesh holes of the drying cylinder 11 to exchange heat with the broken manganese and washed manganese. A small part of the airflow will flow upwards along the periphery of the drying cylinder 11 from the gap between the partition plate 12 and the drying cylinder 11 under the limitation of the partition plate 12, which can also exchange heat with the broken manganese and washed manganese. The material rotates with the drying cylinder 11 and runs to the lower end under the action of gravity. During the forward movement of the wet material in the drying cylinder 11, the wet material directly or indirectly receives heating from the heat carrier, so that the wet material can be dried and then sent out at the discharge end

[0023] In a preferred embodiment, the bottom of the outer cylinder 1 is provided with a residue hopper 2, the bottom of the residue hopper 2 is provided with a discharge valve, the residue hopper 2 is arranged at the bottom of the lower gas chamber, therefore, when the high-temperature gas enters the lower gas chamber, the lower gas chamber is under positive pressure, the manganese residue separated from the drying cylinder 11 will enter the residue hopper 2 for collection, and the discharge valve is added to prevent the high-temperature gas in the lower gas chamber from leaking out of the residue hopper 2.

[0024] It should be noted that the above embodiments all belong to the same utility model concept, the description of each embodiment has its own emphasis, and the description of individual embodiments is not exhaustive, which can be referred to the description of other embodiments.
