Abstract

APARELHO PARA A INTRODUçãO DE UM GáS EM UM CORPO DE LìQUIDO. A presente invenção refere-se a um aparelho para a introdução de gás em um grande corpo de líquido, incluindo um quadro horizontal em bóias de lastro ajustável, uma fonte de gás, pressurizado, um eixo vertical rotativo em torno de seu eixo geométrico, e uma pluralidade de lâminas submersas no líquido e se estendo radialmente a partir de um cubo em uma extremidade inferior do eixo. Cada uma das lâminas tem uma membrana elastomérica em torno de um membro longitudinal, onde o membro longitudinal é oco com uma extremidade fechada e em comunicação com a fonte de gás pressurizado através do eixo na outra extremidade, com aberturas através de seu limite inferior, e a membrana elastomérica tem perfurações as quais são espaçadas das aberturas de membro longitudinal. Um acionamento na plataforma gira o eixo através de uma engrenagem de coroa em torno do eixo com uma conexão de chaveta com ele, permitindo um movimento axial através disso, e uma superfície voltada para dentro suportada em mancais. Uma engrenagem de pinháo seletivamente acionada e menor se encaixa diretamente na engrenagem de coroa.
