본 고안은 열풍건조장치, 더욱 상세히는 흑연도포막을 건조시키기 위한 열풍건조장치에 관한 것이다.The present invention relates to a hot air drying apparatus, and more particularly to a hot air drying apparatus for drying the graphite coating film.

브라운관의 제조공정중, 판넬(Panel), 펀넬(Funnel)의 내,외면에 흑연(Graphi te)을 주성분으로 하는 다그(Dag)도포공정이 있다.In the manufacturing process of the CRT, there is a Dag coating process mainly composed of graphite on the inside and the outside of the panel and the funnel.

이 다그도포공정에서는 흑연을 소정의 두께로서 도포한 후, 히터, 열풍등으로 건조를 실시하게 된다.In this tag application step, graphite is applied at a predetermined thickness and then dried by a heater, hot air or the like.

종래부터 단일의 열풍노즐을 사용하여 판넬(Panel)의 내외면에 열풍을 분사하여 건조시키고 있으나 상술한 건조과정에서는 하기와 같은 문제점을 가진다.Conventionally, a single hot air nozzle is used to dry hot air by spraying the inside and outside surfaces of a panel, but the above drying process has the following problems.

열풍이 단일의 노즐을 통하여 분사되기 때문에 일부분만 집중적으로 건조되어 전체적인 건조과정에서 균열이 발생하기 쉽고 특히 판넬내면의 모서리부에는 열풍이 미치지 않거나 냉각된 열풍이 공급되어 건조상태가 국부적으로 불균일하게 됨에 따라 서로 다른 건조도로 인하여 균열이 발생하여 불량품의 발생을 야기시킨다.Since hot air is sprayed through a single nozzle, only a part of it is intensively dried, so cracks are likely to occur during the entire drying process. As a result, cracks occur due to different dryness levels, resulting in the generation of defective products.

본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로서 상술한 열풍건조장치의 구성을 새롭게하여 판넬 내외면의 건조에 있어서 균일한 건조가 이루어지도록 한다.The present invention has been made to solve such a conventional problem to renew the configuration of the above-described hot air drying apparatus to achieve a uniform drying in the drying of the panel inner and outer surfaces.

이러한 목적을 달성하기 위하여 본고안에 의한 열풍건조장치는 다수개의 노즐을 조합한 노즐어셈블리를 사용한다.In order to achieve this object, the hot air drying apparatus according to the present invention uses a nozzle assembly in which a plurality of nozzles are combined.

이하 첨부된 도면을 참조로 하여 본 고안의 바람직한 하나의 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 열풍건조장치를 설명하는 개략적인 설명도이며 제2도는 본 고안의 열풍건조장치에서 채택되는 노즐어셈블리(NA)를 도시하는 정면도이다.1 is a schematic explanatory diagram illustrating a hot air drying apparatus of the present invention, and FIG. 2 is a front view illustrating a nozzle assembly NA adopted in the hot air drying apparatus of the present invention.

공급되는 에어는 압력조절기(PG)를 통하여 적절한 압력으로서 필터(F)를 거쳐 열풍발생기(HG)로 공급되어 가열된다.The air to be supplied is supplied to the hot air generator (HG) through the filter (F) at an appropriate pressure through the pressure regulator (PG) and heated.

열풍발생기(HG)로부터의 열풍은 온도계(T)에서 일차적으로 배출압력이 측정되어 노즐어셈블리(NA)로 보내어진다.Hot air from the hot air generator (HG) is first measured in the discharge pressure in the thermometer (T) and sent to the nozzle assembly (NA).

노즐어셈블리(NA)는 다수개(바람직하게는 8개)의 노즐(N)을 조합한 형태이며 바람직하게는 열십자(+)형태로 배치하는 것이 좋다.The nozzle assembly NA combines a plurality of nozzles N (preferably eight) and is preferably arranged in a cross shape (+).

본 고안의 열풍건조장치에 사용되는 노즐(N)은 미세한 분사각도의 조정이 보장되는 형상(노즐구의 각을 변경할 수 있는)의 노즐을 사용한다.The nozzle N used in the hot air drying apparatus of the present invention uses a nozzle having a shape (which can change the angle of the nozzle port) in which fine adjustment of the spray angle is ensured.

제2도의 노즐어셈블리(NA)에 있어서 각각의 노즐(N)은 노즐프레임내(NF)의 가로 또는 세로로 다수개 배열 고정되는 고정대(B)에 너트등의 결착수단(M)등으로 탈, 착하거나 위치를 변경할 수 있게 된다.In the nozzle assembly NA of FIG. 2, each nozzle N is detached by a fastening means M, such as a nut, to a fixing table B fixed in a plurality of horizontally or vertically arranged in the nozzle frame NF. It can be nice or change its position.

제조하고자 하는 브라운관의 크기에 따라서 노즐(N)의 위치와 배치간격은 실험적으로 조정된다.According to the size of the CRT to be manufactured, the position and the placement interval of the nozzle N are adjusted experimentally.

상술한 구조의 열풍건조장치는 다수개의 노즐로부터 열풍이 분사되기 때문에 종래와 같이 다그의 균열이 발생하지 않고 건조시간 또한 대폭 단축시킬 수 있는 등의 장점을 가진다.Hot air drying apparatus having the above-described structure has the advantage that the hot air is injected from a plurality of nozzles can be drastically shortened drying time without the crack of the dag as in the prior art.
