Abstract
Provided is an electrode drying apparatus including a moisture supply unit capable of setting the internal temperature of a drying oven to a reference value, which is a level at which the drying of an electrode to be dried is stabilized, before an electrode drying process using hot air is started, thereby preventing the electrode from being fractured by over-drying at the early stage of drying the electrode in the drying oven, and an electrode drying method using the same.
Claims16
An electrode drying apparatus comprising:
- a body comprising:
- an internal accommodation space provided for a drying process;
- an inlet;
- and
- an outlet;
- a transporter configured to transport an electrode to be dried in a single direction so that the electrode to be dried passes through the accommodation space through the inlet and the outlet;
- a hot air supplier configured to blow hot air toward the electrode transported by the transporter so as to dry the electrode to be dried;
- a temperature measurer configured to measure an internal temperature of the accommodation space;
- and
- a moisture supply unit configured to supply moisture into the accommodation space before the electrode to be dried passes through the accommodation space, so that the internal temperature of the accommodation space is lowered to a predetermined reference value, by evaporation of the supplied moisture, and is stabilized,
- wherein the moisture supply unit comprises a moisture spray nozzle configured to supply the moisture in form of a mist so that the moisture is contained in and supplied together with the hot air supplied into the accommodation space by the hot air supplier,
- wherein the moisture supply unit is configured to stop supplying moisture into the accommodation space once the predetermined reference value is reached, and
- wherein, once the accommodation space reaches the predetermined reference value, the transporter is configured to start transporting the electrode to be dried into the accommodation space through the inlet.
