ぼ長方形断面となっている。FIG. 3 is a sectional view of the air cooler cheap, and FIG. 4 is a view taken along the ν arrow in FIG. 3. Air cooler tube 1 has a very large scale? It is easy to clean and the scale is as hard as Shichimento. Currently, we conduct open inspections approximately every two years, and many tubes 1 are completely clogged during these inspections. The air cooler has a shape as shown in Figures 3 and 4, and 1 is a tube 2, and 3 is a cooling fin.The inlet part 1a of the Teague 1 is circular, but the tube part into which the cooling fin 3 is inserted is circular. The tube is crushed to have a substantially rectangular cross section as shown in Figure 4 1b.

った。Therefore, if the valve is fully closed, the solution is to replace tube 1, but since it is not possible to replace only tubes 1 and 2, all tubes must be replaced. However, even at the stage where the tube is clogged, corrosion of the tube itself often does not occur for a long time. [Problem to be solved by the invention] As mentioned above, when the air cooler tube is completely closed. Chemical washing had no effect, so it was necessary to replace all the pipes.
本発明の目的は、上記従来装置の欠点を屏旨し、簡単で
効果のよいスケール除去方法を提供する；ζある。It is an object of the present invention to overcome the drawbacks of the above-mentioned conventional devices and to provide a simple and effective method for removing scale.

にしたものである。The method of removing school from an air cooler tube of the present invention involves cutting out the scale accumulated inside the air cooler tube with a drill cutter having a clear water channel in the center, and simultaneously flushing away the cutting powder with fresh water. It is designed to achieve the above-mentioned purpose.
以下第１〜２図を参照して、本発明の一実施例について
説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
ここにおいて、前記従来装置と同一もしくは、均等構成
部分には、同一符号を用いて説明する。Here, the same or equivalent components as those of the conventional device will be described using the same reference numerals.

ぐイブ内部には冷却水９が流通している。The air cooler 10 shown on the left side of FIG. 1 is composed of an air cooling pipe f1, a tube plate 2, and a cooling fin 3. The air cooling pipe 1 has a part 1b in which the copper guibe is used up and the cooling fin 3 is inserted. is the fourth
As shown in the picture, the bowl has been crushed and the cross section is almost rectangular.
Cooling water 9 is flowing inside the guide.

をしている。The one shown on the right side of FIG. 1 and in FIGS. 2(a) and (b) is an air drill 11, and the outer diameter of the stainless steel gib 7 attached to this air drill 11 via the chuck 6 is the air cooling tube 10. The long field is slightly narrow, and the long field is prepared to match the length of the chive 1. Roughly speaking, the tip of the pipe 7 is screwed onto the stainless steel pipe 7 with a tool. Rinse the scale on the stainless steel via “7” externally with tap water (9).
It is designed to flow out. A guide piece 12 is fitted into the entrance of the Naori-La tube 1 and serves to guide the stainless steel tube 7 that is chucked into the air drill 11.
次に前記実施例の作用について説明する。Next, the operation of the above embodiment will be explained.

ある。When the air cooler tube 1 is clogged with scale, fit the guide plate 12 into the inlet of the air cooler tube 1, insert the stainless steel pipe 7 of the air drill 11 with the cutter 8 attached to the tip using the guide delay F12 as a guide, and remove the cutter 8. At the same time as the scale is cut with the cutting tool, the clean water flowing inside the Qib 7 flushes out the scale powder and cleans the inside of the air cooler tube 1. In this way, the entire scale is cut out with a drill, and after the hole is penetrated, chemical cleaning is performed. It is important to be careful not to damage the air cooler tube 1 when performing the IJ song.

材料費工数の大幅節減が可能となる。The method for removing scale from an air cooler cheap according to the present invention involves attaching a cutting tool to the tip of a hollow pipe to cut off the scale, and then pouring water into the hollow pipe to flush the chips of the scale to the outside with water. Since it is made to come out, even pipes clogged with scale can be easily removed with simple work, and there is no need to replace all the tubes, thus making it possible to significantly reduce material costs and man-hours.
