Description

Lamp train unit for UV irradiation

The present invention is directed to a lamp train unit for ultraviolet irradiation, wherein an insulating plate is disposed between a socket and a support ring of a lamp train unit having a lamp that irradiates and cures UV-curable resin impregnated with an ultraviolet curable resin impregnated in an inner wall of an existing pipe or the like. It is about.

The conventional UV ray irradiation lamp train is inserted into the existing tube and towed while curing the photocurable resin impregnated in the lining material to fix the lining material attached to the inside of the existing pipe.

By the way, the surface temperature of the UV lamp is very high, about 500 ~ 700 ℃, so that the film of lining material is damaged due to overheating, and if the continuous heat is continuously provided in the tube, the temperature rises more than necessary so that the lamp train itself There is a great risk of fire from short circuit.

Thus, in the past, some overheating is avoided by the traction speed or compressed air blowing into the existing pipe (which also serves to push the lining material into the pipe wall), but damage to the lining material and the risk of fire cannot be avoided.

In addition, since both sides of the lamp are fastened while the socket for supporting the lamp and the bridge tube support ring are in contact with each other, the heat of the lamp passes through the bridge tube support ring to the socket and is bad for wires in the socket. May affect
