Horizontal rotary furnace equipped with a spiral movement mechanism and a spiral movement mechanism

摘要

Provided is a spiral-shaped movement mechanism which is easy to create, and which has a structure in which only particles circulate between two reaction chambers and gases are less likely to mix together or a structure through which a gas passes while coming into contact with solid particles at a high density. The mechanism is provided with a first surface plate formed in a disc-like shape, a second surface plate formed in a disc-like shape, a first inlet and a first outlet provided to the first surface plate, a second inlet and a second outlet provided to the second surface plate, a first pathway having a clockwise spiral shape connecting from the first inlet to the second outlet, and a second pathway having a counterclockwise spiral shape connecting from the second inlet to the first outlet.
