The present invention relates to a lacquer drying apparatus of a CRT panel, and more particularly, to a lacquer drying apparatus of a CRT panel capable of supplying dry air suitable for lacquer drying.

In the CRT manufacturing process, the lacquer should be applied after the phosphor is applied to the inner surface of the panel, and after the lacquer is applied, the inner surface of the panel coated with the lacquer should be dried and dried. 1 is a conceptual diagram of a lacquer drying related equipment according to the prior art. Reference numeral 1 designates a conduit through which air entering the screen process passes. The conduit 1 is connected to a heater 2 through which hot steam passes. In the heater 2, the air introduced in the screen process is heated. On the other hand, the heater 2 is in communication with the drying chamber 4 by a conduit 3. Therefore, the air warmed from the heat exchanger 2 flows into the drying chamber 4 to dry the panel (not shown) lying in the drying chamber 4.

In the above process, since the air introduced in the screen process is high in humidity, air must be heated to a high temperature in order to dry the panel. Therefore, in order to heat the air at such a high temperature, a large amount of heat must be applied, resulting in excessive energy loss.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide a lacquer drying apparatus of a CRT panel that can easily dry the lacquer applied to the panel using a small amount of energy Is in.

In order to achieve the object of the present invention described above, the present invention is a conduit through which the air flowing in the screen process passes is connected to the outlet of the conduit and the cooling water passes through, the conduit is communicated by the conduit to the outlet side of the retainer A dehumidifier in which silica gel is incorporated, a heater communicating with an outlet side of the dehumidifier, a heater communicating with a bypass conduit to the conduit, and through which hot steam passes, and a conduit connected to an outlet side of the heater. It provides a lacquer drying device of the CRT panel, characterized in that the drying chamber.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in detail.

2 is a conceptual diagram of one embodiment of a lacquer drying apparatus of a CRT panel according to the present invention. Reference numeral 5 designates a conduit through which air entering the screen process passes. The conduit 5 is connected to a retainer 6 through which cooling water passes. The retainer 6 is in communication with a dehumidifier 9 containing silica gel by a plate 8 having a control valve 7 in the middle thereof. The dehumidifier 9 is in communication with the heater 11 by a conduit 10.

On the other hand, in the conduit 8 the bypass conduit 13 with a control valve 12 is branched and directly connected to the heater 11. The heater 11 is in communication with the drying chamber 15 by a conduit 14.

The operation is as follows. The air introduced in the screening process is introduced into the retainer 6 along the conduit 5, and in the retainer 6, the moisture contained in the air is retained and discharged by the cooling water, thereby dehumidifying the primary air. Most of the dehumidified air enters the dehumidifier 8 through the conduit 8, and the residual moisture contained in the air in the dehumidifier 8 is removed. The dehumidified air is then introduced into the heater 11 along the conduit 10, and a part of the air discharged from the cooler 6 is also introduced into the heater 11. Each amount here is adjustable by means of control valves 7 and 12 so that proper humidity is maintained. Meanwhile, the air introduced into the heater 11 is heated in the heater 11 and flows into the drying chamber 15 through the conduit 14 to dry the lacquer applied to the panel.

According to the present invention, the retainer 6 and the dehumidifier 8 can sufficiently remove the moisture contained in the air flowing in the screening process, so that even if the heater 11 does not apply much heat, The applied lacquer can be dried. Therefore, there is a remarkable energy saving effect.
