AQUEOUS ORGANISM KEEPING APPARATUS Russian patent published in 1998 - IPC

FIELD: aquiculture. SUBSTANCE: apparatus has vessel with water and liquid organofluoric composition circulation loop communicated with water vessel. Circulation loop has organofluoric composition flow initiator, oxygenator, gas flow initiator and gas exchanger. Organofluoric composition and gas flow initiators are mounted in single housing positioned on fish rearing vessel bottom and provided with top and bottom covers. Mentioned initiators are driven by shaft having hollow lower part and disposed within hollow carrier pole, which is hermetically mounted on top cover. Shaft is inserted into pole in hermetically sealed relation to define oxygenator. Central annular bore and radial channel communicated with pressure cavity of gas flow initiator are made in top cover. Shaft cavity is communicated via openings with annular bore and with loop cavity lower part, which is communicated via pipeline with outlet branch pipe of organofluoric composition flow initiator, whose inlet opening is disposed in bottom cover. Flow turbulators mounted on shaft in pole cavity are made in the form of finned rings and spirals. Gas-saturated organofluoric composition outlet openings are disposed in upper part of carrier pole. EFFECT: increased efficiency in usage of oxygen-containing medium, in particular, organofluoric composition, simplified construction and improved aqueous organism keeping conditions. 3 dwg
