Axial-flow aerator for aeration
专利汇可以提供Axial-flow aerator for aeration专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce the lift head of air suction to a smallest possible extent and to effectively facilitate the supply of oxygen into water with saved power consumption, by using a propeller-type axial-flow pump as an aerator to be used in the disposal of water or the like. CONSTITUTION:A guide cylinder 3 is arranged in an axial-flow pump 1. A motor 30 is attached in the guide cylinder 3, to rotate an impeller 5. An air-introducing pipe 9 is arranged in the mouthpiece pipe 7 of the axial-flow pump 1. A bevel discharge opening 10 at the top end of the pipe 9 is opened near the impeller 5. By the rotation of the impeller 5, water is sucked through the mouthpiece pipe 7 and flows outside the air-discharge opening 10. At this time, a negative pressure is generated due to the flow speed of the water, so that air is sucked into the introducing pipe 9 and mixed into water as fine bubbles from the discharge opening 10. The gas-liquid mixture is pressurized by the rotation of the impeller 5, rectified with rectifier plates 4, 13, and discharged into the water through a spout pipe 12. An air-suction amount is adjusted by a resisting means 11 attached to the introducing pipe 9.，下面是Axial-flow aerator for aeration专利的具体信息内容。
