The invention discloses a battery
raw material circulation
drying device which comprises a
drying box, an
air heater is arranged outside the
drying box, a dehumidification box is arranged between the drying box and the
air heater, the drying box is connected with the
air heater through a hot air
pipe, the drying box is connected with the dehumidification box through a
backflow pipe, a partition plate is arranged in the drying box, and an upper air duct and a lower air duct are arranged in the drying box. The upper
air channel and the lower
air channel are located on the upper side and the lower side of the partition plate and provided with corresponding material passing openings, stirring propellers are arranged in the upper
air channel and the lower air channel, an air guide fan is arranged on the left side of the upper air channel, an air guide fan is arranged on the right side of the lower air channel, and a temperature sensor and a
humidity sensor are further arranged in the drying box. By arranging the upper air duct and the lower air duct and arranging the air guide fans in the upper air duct and the lower air duct, flowing of hot air in the drying box is promoted, and the drying speed is increased. A temperature sensor and a
humidity sensor are arranged in the drying box, the temperature and
humidity in the drying box can be monitored in real time, and data support is provided for accurately controlling the drying process. The PLC can automatically adjust the operation states of the air heater, the air guide fan, the
electromagnetic valve, the dehumidification fan and other devices according to feedback signals of the temperature sensor and the humidity sensor, and it is ensured that the drying process is conducted under the optimal temperature and humidity conditions.
