<p>PROBLEM TO BE SOLVED: To provide an air feeder of an oil component blocking device simple in installation work. SOLUTION: The air feeder is constituted of an air pump 2 arranged outside a grease trap 1, a flexible intermediate pipe comprising a vinyl chloride resin, or the like, a joint 4, a flexible final pipes 5, or the like. The final pipes 5 are connected to the air outlets formed to the joint 4 at three places and core materials such as stainless steel wires are inserted in the final pipe 5 and weights 7 are provided to the leading ends 51 of the final pipes 5 and a large number ob holes are bored in the final pipes 5 over the constant length parts from the leading ends thereof, and the final pipes 5 are arranged in three tanks 13a-13c of the grease trap 1 so that the leading ends 51 reaches the bottoms 11a-11c of the tanks. The core materials of the final pipes can be easily bent correspondingly to the shape of the grease trap 1 by the hand and the shape thereof after bending can be held and the whole of the air feeder can be easily mounted. Air is blown out of the leading ends of the final pipes to certainly stirr and aerate the water in three tanks 13a-13c.</p> |
