【考案の詳細な説明】
本考案は高温下において吹付作業を行う吹付装置、特に

キーとキー溝を設けなくてはならなかった。The water cooling structure of the conventional spray equipment has a double pipe structure for the spray pipe, the inside of the inner tube is a small spray pipe feeding path or a spraying material feeding path, and the gap between the pipe walls is divided into one by a partition wall, and multiple pipes are used. The mechanism for rotating, advancing and retracting the spray pipe required a guide or key and key groove to be provided separately from the water cooling structure.
そのため、管壁間隙部を仕切壁を1分又は複数分割する
ことは製作上難しく、又工数を要するものであり、更に
吹付パイプの回転、進退させる機構のガイド又はキーと
キー溝を別途製作せねばならないので製作工数がこの点
でも増大するといった欠点があった。Therefore, dividing the pipe wall gap into one or more partition walls is difficult to manufacture and requires a lot of man-hours, and it is also necessary to separately manufacture a guide or key and key groove for the mechanism for rotating, advancing and retracting the spray pipe. This also has the drawback of increasing the number of manufacturing steps.
本考案はこれらの欠点を除去し、製作が容易でしかも工

装置に係るものである。In this invention, part or all of the large spray pipe 1 has a double pipe structure, the inside of the inner pipe of the double pipe structure is used as the small spray pipe supply path, and the gap between the pipe walls is used as the cooling water channel 3. The present invention relates to a spraying device in which a spraying pipe is water-cooled and is characterized in that a water pipe 4 is arranged in parallel to a spraying pipe 1 so as to communicate with the cooling channel 3.

。The structure of the combination of the small spray pipe 7 and the small pipe guide roller 9 may be any structure as long as it can freely move forward and backward and rotate as a unit; for example, the combination of the small spray pipe 7 and the large spray pipe 1 may
It may be of a structure in which a key and a keyway are formed between the key and the keyway.

かも有効なものとなっている。In this design, the sprayer's pipe 1 has a double pipe structure, with the inner side serving as the small spray pipe feed passage 2, and the gap between the pipe walls serving as the cooling water passage 3.
By doing so, the heat to the small spray pipe 7 is blocked by the cooling water channel 3, and the large spray pipe 1 itself is cooled by the cooling water channel 3 to prevent thermal deformation and strength reduction, and the small spray pipe is cooled. This prevents the temperature rise of the small spray pipe 7 that directly feeds the spray material, and since the return channel is discharged through the water pipe 4 installed in parallel outside, it is possible to form a reciprocating channel in the cooling channel of the spray pipe as in the past. There is no need to provide a partition wall, making the production extremely easy. Furthermore, the water pipes installed in parallel on the vertical part provide ample force for rotation and movement (in the figure, the large spray pipe 1 connects to the rotating cylinder 11). (The water pipe 4 is used as a guide and is inserted loosely.) It is structurally simple and effective.
従って、本考案によれば水冷した吹付パイプの構造が製
作上容易になると共に、回転、進退構造も簡略化できる
という効果がある。Therefore, according to the present invention, the structure of the water-cooled spray pipe can be easily manufactured, and the rotating and advancing/retracting structures can also be simplified.
