Hereinafter, non-limiting embodiments of the present disclosure will be further described with reference to specific embodiments and drawings.

However, the embodiments are only given for illustrating the present disclosure and those skilled in the related art will obviously understand that various alterations and modifications are possible within the scope and spirit of the present disclosure. Such alterations and modifications are duly included in the appended claims.
A drying apparatus according to a non-limiting embodiment of the present disclosure includes an upper drying part 10 having a first drying nozzle 11 which is formed above an object to be dried E and which extends along a width direction w of the object to be dried E and having a second drying nozzle 12 formed on the same surface as the first drying nozzle 11, and includes a lower drying part 20 having a lower drying nozzle 21 which is formed below the object to be dried E and which extends along the width direction w of the object to be dried E. Furthermore, the first drying nozzle 11 and the second drying nozzle 12 may dry the object to be dried with different heat sources.
In the present disclosure, the term ‘object to be dried E’ collectively refers to an object that will be dried, and refers to various objects to be dried in a sheet form. Although drying of an electrode plate in the secondary battery field has been illustrated as an example, the object to be dried E of the present disclosure is not limited to the electrode plate, and the object to be dried E of the present disclosure may be various objects to be dried E for resolving a deviation in the position during drying and for resolving an imbalance of various drying amounts during drying.
As illustrated in
The first drying nozzle 11 and the second drying nozzle 12 may dry the object to be dried E by using different heat sources. The first drying nozzle 11 may include a hot air heater and may dry the object to be dried E by a hot air method, and the second drying nozzle 12 may include an infrared heater and may dry the object to be dried E by a radiation method.
In addition to the mixed arrangement of the first drying nozzle 11 and the second drying nozzle 12, by drying the object to be dried E using the first drying nozzle 11 and the second drying nozzle 12 in different methods, a margin of heat source for the object to be dried E may be secured.
The first drying nozzle 11 and the second drying nozzle 12 may be formed such that the first drying nozzle 11 and the second drying nozzle 12 extend in the width direction w in a moving direction of the object to be dried E, and may be disposed to be spaced apart from each other by a predetermined distance. When the object to be dried E is dried, non-drying of both end parts in the width direction w of the object to be dried E or overdrying of a center portion of the object to be dried E may occur. Therefore, the drying heat and the drying position may be adjusted by the first drying nozzle 11 and the second drying nozzle 12.
The second drying nozzle 12 may include the infrared heater using radiant heat, and may be provided as a plurality of second division nozzles 12a formed by a predetermined distance in a longitudinal direction in which the second drying nozzle 12 is formed. As illustrated in the drawings, the plurality of second division nozzles 12a is divided into a first side and a second side along the longitudinal direction of the object to be dried E. That is, the plurality of second division nozzles 12a is divided into an upper portion and a lower portion in the plan view in
That is, since the plurality of second division nozzles 12a is disposed to be spaced apart from each other in the width direction w of the object to be dried E, the drying temperature, the position, and the drying amount of the object to be dried E in the width direction w by the second drying nozzle 12 together with the drying performed by the first drying nozzle 11 may be appropriately adjusted.
In this case, the second division nozzles 12a may be individually controlled, so that the drying temperature may be adjusted appropriately and the operation of the apparatus for the position may be turned on and turned off appropriately according to the overdried position or non-dried position of the object to be dried E. At this time, the plurality of second division nozzles 12a may be divided into the upper portion and the lower portion respectively in a progression direction of the object to be dried E. In this case, the second division nozzle 12a at the upper portion may be controlled to be operated with the same output by using one control range, and the second division nozzle 12a at the lower portion may be controlled to be operated with the same output by using another control range, so that entire of the plurality of second division nozzles 12a may be controlled to be operated with the same output. In this manner, the division nozzles at the upper portion and the lower portion of the second drying nozzle 12 of the upper drying part 10 may be individually controlled.
In the second drying nozzle 12, together with the plurality of second division nozzles 12a, a second single nozzle 12b, which is similar to the first drying nozzle 11, that is not divided may be arranged in a mixed manner.
Since the second single nozzle 12b and the second division nozzle 12a have different shapes, the drying temperature and so on may be individually controlled for each shape, and the plurality of the second single nozzles 12b may be controlled together to be operated with the same output independently of the second division nozzles 12a.
By appropriately arranging and mixing the drying of first drying nozzle 11 using the hot air method and the drying of the second drying nozzle 12 using the radiant heat method, the drying of the object to be dried E may be controlled more precisely.
On the basis of the length in the width direction w of the object to be dried E, a formation length A1 of the first drying nozzle 11 may be formed 1.5 times to 2 times a length B1 of the single second division nozzle 12a of the second drying nozzle 12. In addition to the first drying nozzle 11 using the basic hot air method, the second drying nozzle 12 capable of more precisely performing control for the position and for the drying temperature may be disposed in a form of the second division nozzles 12a and the second single nozzle 12b. Through a relative ratio of lengths a1, c1, and c2 of the first drying nozzle 11 and the second drying nozzle 12, the drying degree in which the object to be dried E is dried by the plurality of heat sources, the drying temperature, the drying position, and so on may be more precisely controlled. In addition, durability of the drying apparatus may be secured by physically arranging the first drying nozzle 11 and the second drying nozzle 12, and the mutual interference between heat sources occurring due to the using of the different heat sources during the drying process may be minimized, so that the drying deviation may be reduced more precisely.
Here, in order to more effectively prevent non-drying of ends in the width direction w of the object to be dried E and so on, the first drying nozzle 11 and the second drying nozzle 12 may be disposed such that the first drying nozzle 11 and the second drying nozzle 12 cover both ends in the width direction w of the object to be dried E. That is, the first drying nozzle 11 and the second drying nozzle 12 may be respectively disposed such that the second drying nozzle 12 is aligned with the both ends in the width direction w of the object to be dried E when the second drying nozzle 12 is divided into the plurality of second drying nozzles 12. In addition, the plurality of second division nozzles 12a may align each first end of the second division nozzles 12a to the same position by adjusting the distance between the plurality of second division nozzles 12a.
The first drying nozzle 11 and the second drying nozzle 12 may be formed such that the first drying nozzle 11 and the second drying nozzle 12 are spaced apart from each other, a width a2 in the longitudinal direction of the first drying nozzle 11 may be formed from 150 mm to 250 mm, and widths b2 and c2 in the longitudinal direction of the second drying nozzle 12 may be formed from 130 mm to 180 mm.
In order to adjust the drying degree due to the different heat sources, the widths are appropriately adjusted with in the ranges, so that the reliability of the drying effect on the object to be dried E may be increased.
As illustrated in
The lower drying nozzle 21 may be disposed such that the lower drying nozzle 21 faces the first drying nozzle 11 or the second drying nozzle 12 of the upper drying part 10, and the lower drying nozzles 21 have widths the same as the widths of the facing drying nozzles, so that the drying deviation on the upper surface and the lower surface of the object to be dried E may be effectively controlled.
The lower drying nozzle 21 may be formed such that the lower drying nozzle 21 has the same width and length as the first drying nozzle 11, and a width d2 in a longitudinal direction of the lower drying nozzle 21 may be formed from 150 mm to 250 mm. The lower drying nozzle 21 may be formed such that a length d1 of the lower drying nozzle 21 corresponds to that of the first drying nozzle 11 facing the lower drying nozzle 21.
As illustrated in
As illustrated in
Specifically, as illustrated in
The guide rail 31 may be disposed correspondingly on a separation space between the first drying nozzles 11 or the second drying nozzles 12 in order to minimize interference during the drying process performed by the first drying nozzle 11 or the second drying nozzle 12 while physically moving the shielding plate 32. In addition, of course, the shielding adjustment part 30 may be formed of a material having a low thermal conductivity so that the residual heat generated by the first drying nozzle 11 or the second drying nozzle 12 is not transferred to the object to be dried E.
The drying apparatus according to a non-limiting embodiment of the present disclosure includes the upper drying part 10 having the first drying nozzle 11 which is formed above the object to be dried E and which extends along the width direction w of the object to be dried E and having a second drying nozzle 13 which is formed on the same surface as the first drying nozzle 11 and which is formed of a heat source different from the first drying nozzle 11. Furthermore, the second drying nozzle 13 includes a single drying nozzle 13b on the first side in the width direction of the object to be dried E and a multi-drying nozzle 13a on the second side in the width direction of the object to be dried E, and the single drying nozzle 13b and the multi-drying nozzle 13a may be formed such that the single drying nozzle 13b and the multi-drying nozzle 13a are alternately arranged on the first side and the second side in the longitudinal direction of the object to be dried E.
The first drying nozzle 11 and the second drying nozzle 13 may be formed on the same plane of the upper drying part 10. Drying methods by heat sources different from each other may be applied to the first drying nozzle 11 and the second drying nozzle 13, respectively. In the present disclosure, the drying method performed by hot air may be applied to the first drying nozzle 11, and the drying method performed by the infrared heater may be applied to the second drying nozzle 13.
The second drying nozzle 13 may be arranged alternately with the first drying nozzle 11, or may be applied to all or part structures of the upper drying part 10. Furthermore, in consideration of the drying deviation of the object to be dried E, of course, the arrangement method of the first drying nozzle 11 and the second drying nozzle 13 may be changed appropriately.
As illustrated in
Of course, the single drying nozzle 13b and the multi-drying nozzle 13a may be formed in a separated shape by being divided from each other in the formation direction of the first drying nozzle 11, and the divided size or the divided shape thereof may be appropriately changed without being limited to the one illustrated.
As illustrated in
In the upper portion in
In addition, of course, the drying deviation for the entire object to be dried E is capable of being adjusted and controlled by respectively setting a control range such that a control range in which the single drying nozzles 13b are controlled and a control range in which the multi-drying nozzles 13a are controlled are set.
In addition, although the single drying nozzle 13b and the multi-drying nozzle 13a have different numbers of infrared heaters, the distance of the formation space has an equal distance in the movement direction of the object to be dried E, so that the drying degree within the same distance range may be effectively controlled.
The present disclosure has been described in detail through specific embodiments. An embodiment is intended to describe the present disclosure in detail, and the present disclosure is not limited to the embodiment. The present disclosure can be variously modified by those skilled in the art without departing from the scope of the technical idea of the present disclosure.
Furthermore, simple changes and modifications of the present disclosure are appreciated as included in the scope and spirit of the present disclosure, and the protection scope of the present disclosure will be defined by the claims.
