Next, after pulling out the flange portions 46 and 56 from the processing tank 14 together with the spray pipe 22 and the liquid supply pipe 48, the operator loosens the fastening member 90 of the second clamp member 61 and removes it from the connection portions 82 and 83. Thereafter, the clamp arms 78 and 79 are opened around the hinge 80, and the second clamp member 61 is detached from the outer peripheral side of the flange portions 46 and 56. As a result, the liquid inlet flange portion 46 and the liquid outlet flange portion 56 can be separated, so that the operator pulls the liquid outlet flange portion 56 away from the liquid inlet flange portion 46 while bending the flexible pipe 50, and then the flange. The seal ring 86 is recovered from between the surfaces 47 and 57.
[0037]
Before the tip of the spray tube 22 comes out of the support member 26, the operator rotates the spray tube 22 in which the spray nozzle 23 faces the direction of the aluminum web 12 by approximately 180 ° and points the spray nozzle 23 upward. Thereafter, the spray tube 22 is pulled out until the tip part is removed from the support member 26, and the spray tube 22 is further pulled out from the processing tank 14 to the outside.
[0038]
After the used spray tube 22 is extracted from the processing tank 14 as described above, the operator inserts the tip end side of the spray tube 22 that has been maintained into the processing tank 14 through the insertion / removal hole 36. At this time, the tip of the spray tube 22 is placed on the guide surface 96 with the spray nozzle 23 facing upward. In this state, the operator inserts the tip of the spray tube 22 in the direction of the support member 26 while sliding on the guide surface 96. At this time, before the rear end portion of the spray pipe 22 is inserted into the processing tank 14, the operator temporarily interrupts the insertion of the spray pipe 22 into the processing tank 14, and the flange surface outside the processing tank 14. After attaching the seal ring 86 to either 47 or 57, the second clamp member 61 is fitted on the outer peripheral side of the flange portions 46 and 56 to connect the flange portions 46 and 56. As a result, the flange portions 46 and 56 are connected, the liquid supply pipe 48 is connected to the spray pipe 22, and the seal ring 86 between the flange surfaces 47 and 57 is compressed to seal between the flange surfaces 47 and 57. Ru
When the connection of the flange portions 46 and 56 by the second clamp member 61 is completed, the operator inserts the spray tube 22 into the support member 26 again, and inserts the distal end portion 34 of the spray tube 22 into the support member 26. After that, the spray tube 22 is rotated by approximately 180 °, and the spray nozzle 23 is directed toward the aluminum web 12 as shown in FIG. In this state, after the seal ring 76 is attached to one of the flange surfaces 41 and 43, the operator brings the flange surfaces 41 and 43 into contact with each other via the seal ring 76. Thereafter, the operator connects the flange portions 40 and 42 by inserting and inserting the first clamp member 59 on the outer peripheral side of the flange portions 40 and 42. Thereby, the rear end side of the spray tube 22 is fixed via the nipple member 52, and the replacement operation of the spray tube 22 with respect to the processing tank 14 is completed.
[0039]
According to the mounting structure 104 according to the present embodiment described above, in addition to obtaining the same function and effect as the mounting structure 24 according to the first embodiment, in a state where the spray tube 22 is mounted on the treatment tank 14, Since the liquid inlet flange portion 46 and the liquid outlet flange portion 56 connected by the first clamp member 59 are located in the connecting member 38 communicating with the inside of the processing tank 14, the processing liquid L is interposed between the flange portions 40 and 42. Even if the liquid leaks, the effect that the processing liquid L does not flow out of the processing tank 14 can be obtained.
[0040]
Further, when any one of the attachment structures 24 and 104 is applied to the embodiment of the present invention, the conventional spray tube in which the operator must replace the spray tube 22 in the treatment tank 14 when the web processing apparatus 10 is applied. Compared with the mounting structure, the working time per spray tube 22 can be reduced from about 20 minutes to about 5 to 8 minutes, and the treatment liquid L leaks between the liquid supply pipe 48 and the spray pipe 22. In addition, leakage of the processing liquid L from the inside of the processing tank 14 to the outside did not occur for a long time.
[0041]
Here, only the case where the mounting structures 24 and 104 according to the embodiment of the present invention are applied to the web processing apparatus 10 has been described. However, these mounting structures 24 and 104 are not limited to the web processing apparatus 10 and may be sprayed. The present invention can be applied to various apparatuses that use the pipe 22 in equipment such as a processing tank partitioned from the outside. For example, continuous casting equipment such as iron and aluminum, and various long products can be continuously used in the processing tank. It can also be applied to cleaning equipment for cleaning. Further, in the mounting structures 24, 104, a pair of clamp arms 63, 64, 78, 79 that can be opened and closed around the hinges 65, 80 in order to connect the flange portions 40, 42 and the flange portions 46, 56 and these. Although the clamp members 59 and 61 provided with the fastening members 70 and 90 for connecting the tip portions of the lamp arms are used, the clamp members 59 and 62 having such a structure are not necessarily used, and the screw-type fastening is used. Instead of the members 70 and 90, a lever-type fastening member may be used, or a pinch-type clamp member that sandwiches and connects the flange portions 40 and 42 or the flange portions 46 and 56 from the outside may be used. good.
