Abstract

An electrode drying device includes a chamber through which an electrode plate is passable, and an upper adjustment unit in the chamber and configured to adjust hot air above the electrode plate to prevent non-uniform drying of the electrode plate due to a difference in flow rate.

First claim

What is claimed is:

1 . An electrode drying device comprising:
a chamber through which an electrode plate is passable; and an upper adjustment unit in the chamber, and configured to adjust hot air above the electrode plate to prevent non-uniform drying of the electrode plate due to a difference in flow rate.

2 . The electrode drying device as claimed in claim 1 , wherein the upper adjustment unit comprises:
a plurality of upper exhaust portions configured to discharge a drying gas from the chamber; and an upper air supply portion between the upper exhaust portions and configured to supply the drying gas.

3 . The electrode drying device as claimed in claim 2 , wherein the upper exhaust portion comprises:
an upper exhaust discharge pipe passing through the chamber to discharge the drying gas to an outside of the chamber; an upper exhaust duct connected to the upper exhaust discharge pipe and configured to face the electrode plate; and an upper exhaust nozzle connected to the upper exhaust duct and into which the drying gas is introduced.

4 . The electrode drying device as claimed in claim 3 , wherein the upper exhaust nozzle comprises a plurality of upper exhaust nozzles spaced apart from each other in a longitudinal direction of the upper exhaust duct.

5 . The electrode drying device as claimed in claim 3 , wherein the upper exhaust nozzle comprises:
an exhaust nozzle pipe connected to the upper exhaust duct and arranged above the electrode plate; and an exhaust distribution portion in the exhaust nozzle pipe and configured to induce uniform exhaust.

6 . The electrode drying device as claimed in claim 5 , wherein the exhaust distribution portion comprises:
an exhaust distribution plate in the exhaust nozzle pipe; and an exhaust distribution hole extending through the exhaust distribution plate and through which the drying gas passes.

7 . The electrode drying device as claimed in claim 3 , wherein the upper exhaust portion further comprises:
an upper exhaust connection pipe configured to connect a plurality of upper exhaust discharge pipes; an upper exhaust extending pipe extending from the upper exhaust connection pipe and configured to discharge the drying gas; and an upper exhaust fan in the upper exhaust extending pipe and configured to discharge the drying gas.

8 . The electrode drying device as claimed in claim 2 , wherein the upper air supply portion comprises:
an upper air supply pipe passing through the chamber to supply the drying gas into the chamber; an upper air supply duct connected to the upper air supply pipe and configured to face the electrode plate; and an upper air supply nozzle connected to the upper air supply duct and through which the drying gas is supplied into the chamber.

9 . The electrode drying device as claimed in claim 8 , wherein the upper air supply nozzle comprises a plurality of upper air supply nozzles spaced apart from each other in a longitudinal direction of the upper air supply duct.

10 . The electrode drying device as claimed in claim 8 , wherein the upper air supply nozzle comprises:
an air supply nozzle pipe connected to the upper air supply duct and arranged above the electrode plate; and an air supply distribution portion in the air supply nozzle pipe and configured to induce uniform air supply.

11 . The electrode drying device as claimed in claim 10 , wherein the air supply distribution portion comprises:
an air supply distribution plate in the air supply nozzle pipe; and an air supply distribution hole extending through the air supply distribution plate and through which the drying gas passes.

12 . The electrode drying device as claimed in claim 2 , wherein the upper adjustment unit further comprises upper insulating portions between the upper exhaust portions and the upper air supply portion and configured to maintain a temperature of the upper air supply portion.

13 . The electrode drying device as claimed in claim 1 , further comprising a lower adjustment unit in the chamber and configured to adjust hot air under the electrode plate.

14 . The electrode drying device as claimed in claim 13 , wherein the lower adjustment unit comprises:
a lower air supply pipe passing through the chamber to supply the drying gas into the chamber; a lower air supply duct connected to the lower air supply pipe and configured to face the electrode plate; a lower air supply nozzle connected to the lower air supply duct and through which the drying gas is supplied into the chamber; and a lower exhaust pipe connected to the chamber to discharge the drying gas to an outside.

15 . An electrode drying device comprising:
a chamber through which an electrode plate is passable; a pair of upper exhaust portions configured to discharge a drying gas from the chamber; and an upper air supply portion between the upper exhaust portions and configured to supply the drying gas, wherein the drying gas from the upper air supply portion is exhausted by the upper exhaust portions to prevent a flow rate deviation from occurring in the chamber.

16 . The electrode drying device as claimed in claim 15 , wherein the upper exhaust portions comprise:
a pair of upper exhaust discharge pipes passing through the chamber to discharge the drying gas to an outside of the chamber; a pair of upper exhaust ducts respectively connected to the pair of upper exhaust discharge pipes and configured to face the electrode plate; and upper exhaust nozzles connected to the pair of upper exhaust ducts and into which the drying gas is introduced.

17 . The electrode drying device as claimed in claim 16 , wherein the upper exhaust nozzles comprise:
first exhaust nozzles arranged across the pair of upper exhaust ducts and connected to each of the pair of upper exhaust ducts; and a second exhaust nozzle between the first exhaust nozzles and comprising opposite end portions connected to the first exhaust nozzles.

18 . The electrode drying device as claimed in claim 16 , wherein the upper air supply portion comprises:
an upper air supply pipe between the upper exhaust discharge pipes, and passing through the chamber to supply the drying gas into the chamber; an upper air supply duct between the upper exhaust ducts, connected to the upper air supply pipe, and configured to face the electrode plate; and upper air supply nozzles between the upper exhaust nozzles, connected to the upper air supply duct, and through which the drying gas is supplied into the chamber.

19 . The electrode drying device as claimed in claim 18 , wherein the upper air supply nozzles comprise:
a first air supply nozzle arranged across the upper air supply duct and connected to the upper air supply duct; and second air supply nozzles extending from opposite end portions of the first air supply nozzle and located between the upper exhaust nozzles.

20 . The electrode drying device as claimed in claim 18 , wherein angles of the upper exhaust nozzles and the upper air supply nozzles are adjustable.
