Abstract
A vertical roasting furnace and a battery material processing device. The vertical roasting furnace comprises a vertical furnace body (1), a feeding mechanism (2), sintering pipes (3), and a heating mechanism (4). The vertical roasting furnace uses a vertical structure, and under the action of gravity, materials sequentially flow through a plurality of reaction zones in a material sintering cavity (10) in a fluid state, so as to carry out real-time transmission and dynamic heating and cooling on the materials, thereby realizing dynamic sintering of the materials and improving the sintering effect. In addition, there is no need to provide a power device for driving the materials to move, thereby saving energy. The dried materials having a high temperature do not need to be loaded into a saggar for cooling, but are directly introduced into the top reaction zone in the material sintering cavity (10) by means of the feeding mechanism (2), thereby improving the sintering efficiency of the materials.
