Abstract

용기내에서 선택적으로 폭기 또는 비폭기적으로 액체를 혼합하기 위한 장치가 수직 축선에 관하여 회전할 수 있도록 용기(1)의 바닥 구역에 배치된 중공의 별형상 다익 회전자(6)를 포함한다. 회전자(6)의 두 대향면 중하나에서 회전자(6)의 중공 내부는 기체 공급라인(15)과 연결되며, 회전자(6)의 회전 방향으로 도시된 바와 같이 추적 측면(11)에서 날개(10)들 각각은 기체 배출구(12)를 구비한다. 액체는 기체-액체 혼합물용 흐름통로로 고정자에 의해 둘러 쌓인 회전자(6)의 두 수평면 중 하나로 들어간다. 기체주사가 없을 때라도 장치가 액체를 순환 시키기 위해 확실히 사용될 수 있도록 회전자는 유입 액체흐름(17)으로 부터 기체 배출구(12)를 통해 배출되는 기체흐름(16)을 분리하기 위해 각각의 안내판(18)들을 각진 틈 또는 공간에 구비한다.
