PURPOSE:To prevent any drain failure from occurring by installing both vertical and horizontal shafts formed solidly with a blade and formed into L-shaped form, in a tip part of the blade, and making a brush contact with the bottom of a drain centralized groove. CONSTITUTION:A vertical shaft 3 and a horizontal shaft 5 formed solidly with a blade 2 and formed into L-shaped form each are installed in a tip part 2a of the blade 2 being driven by a motor 1. A blush 4 installed in a lower part of the horizontal shaft 5 comes into contact with the bottom 7 of a drain centralized groove 6. A casing 8 has a fluid inlet port 8a and a discharge port 8b. Drain water on the bottom of the drain centralized groove 6 is stirred by this brush 4. Thus, dust or the like is not accumulated on the bottom of the drain centralized groove so that any drain failure due to sludge or the like is thus preventable. |
