を変更できないという欠点があつた。Here, the raw water is slowly stirred by the slow stirrer 10 to produce sediment, which flows into the settling tank 11 and is separated into treated water and sludge. The purified treated water flows out into the overflow gutter 12 and is discharged from the treated water outflow pipe 12a. On the other hand, the sludge accumulated at the bottom of the settling tank 11 is scraped into the sludge storage tank 14 by the sludge scraping rake 13 and discharged from the sludge discharge pipe 14a. The conventional flocculant mixing pipe mixer 4 in the above-mentioned coagulation-sedimentation apparatus is connected to the straight part of the raw water inflow pipe using flanges on both sides, which requires time and effort to attach and detach during maintenance and inspection. However, there was a drawback that the length could not be changed after it was installed.

。In Figure 2, the same reference numerals as in Figure 2 represent the same or equivalent items. Raw water tank 1
Inside, there is a riser pipe 2 that supplies raw water with a raw water pump 2.
A raw water supply pipe 22 is connected to the upper part of the riser pipe 21 so as to be perpendicular to each other and has a pipe end flange 22a. Raw water supply pipe 2
A pipe mixer 23 is installed in the pipe No. 2, which is inserted from the pipe end flange 22a side. Pipe mixer 2
3 is formed of a shaft 23a and semi-elliptical wing plates 23b welded to both sides of the shaft 23a in an alternately inclined manner. The outer circumference of the blade plate 23b is an elliptical arc centered on the axis of the shaft 23a, and the outer diameter of the blade plate 23b is the same as that of the raw water supply pipe 22.
It is formed slightly smaller than the inner diameter of. Thus, the pipe mixer 23 is inserted into the raw water supply pipe 22. The shaft end on the installation side of the pipe line mixer 23 is provided with a threaded surface, and a shaft end flange 25 is mounted via a nut 24. After inserting the pipe mixer 23, the shaft end flange 2
5 is attached to the tube end flange 22a via a packing 26 with a mounting bolt 27. 25a is a handle.
