The invention discloses a
cobalt hydroxide rotary
drying device which comprises a base, a support, a feeding device, a low-temperature
drying device, a high-temperature
roasting device and a cooling device. The feeding device, the low-temperature
drying device, the high-temperature
roasting device and the cooling device are sequentially fixed on the base, wherein the support is arranged at the lower end of the base and used for supporting, the low-temperature drying device comprises a first heat preservation layer and a first
electric heating furnace tube arranged in the first heat preservation layer, and the high-temperature
roasting device comprises a second heat preservation layer, a second
electric heating furnace tube, a rotary cylinder body and a lifting board. The second
electric heating furnace tube is arranged between the heat preservation layer and the rotary cylinder body, the lifting board is vertically arranged on the inner wall of the rotary cylinder body, the cooling device comprises a third heat preservation layer and a cooler arranged in the third heat preservation layer, and the cooling device is used for conducting cooling and discharging on dried
cobalt hydroxide. The
cobalt hydroxide rotary drying device has the advantages that the yield is large,
energy consumption is low, the temperature is uniform and few
metal foreign bodies are led in.
