Cathode material drying device and cathode material drying production line

Abstract

This application discloses a cathode material drying device and a cathode material drying production line. The cathode material drying device includes: a rotary kiln, where a kiln head and a kiln tail of the rotary kiln each are provided with a sealing structure and the rotary kiln can rotate relative to the sealing structure; and an exhaust system comprising an air inlet pipe, an air outlet pipe, and a first fan, where the air inlet pipe communicates with the kiln tail of the rotary kiln through the sealing structure; the air outlet pipe communicates with the kiln head of the rotary kiln through the sealing structure; and the first fan is arranged on the air inlet pipe and/or the air outlet pipe, so as to make an air flow direction in the rotary kiln opposite to a delivery direction of a cathode material.
