Aerator assembly for diffusing a gas in a liquid
An aerator assembly for diffusing a gas in a liquid, including a gas supply conduit and at least one aerator, wherein the gas supply conduit and the aerator are releasably joined to each other by an attachment. The attachment includes a flexible body and a compressor, wherein the attachment is arranged to be reversibly set in an inactive mode, in which the gas supply conduit and the at least one aerator are in mutually released mode, as well as in an active mode in which the flexible body is compressed in its axial longitudinal direction by the compressor and clamps the at least one aerator and the gas supply conduit against each other.
1. An aerator assembly for diffusing a gas in a liquid comprising:
a gas supply conduit and at least one aerator, the gas supply conduit comprising a pipe wall delimiting an inner gas supply chamber and said at least one aerator comprising a holder having an inner space,
wherein the gas supply conduit and the aerator are releasably joined to each other by an attachment means extending from the inner space of the holder to said inner gas supply chamber and comprising a duct for fluid communication between the inner space of the holder and the gas supply chamber,
wherein the attachment means comprises a flexible body and a compression means, the flexible body being tubular and having a first end and an opposite second end, and the compression means of the attachment means comprising a screw and a nut, which are in engagement with each other,
wherein said nut is joined to the tubular flexible body at the area of the first end, and said screw extends from a second end of the tubular flexible body to said first end,
wherein the attachment means is arranged to be reversibly set in an inactive mode, in which the gas supply conduit and said at least one aerator are in mutually released mode, as well as in an active mode in which the flexible body is compressed in its axial longitudinal direction by the compression means and clamps said at least one aerator and the gas supply conduit against each other.
2. The aerator assembly according to claim 1 , wherein, the flexible body is elastic.
3. The aerator according to claim 1 , wherein, the flexible body is made of an elastomer.
4. The aerator according to claim 1 , wherein, the tubular flexible body, at the area of the second end, comprises a radially extending flange.
5. The aerator assembly according to claim 1 , wherein, the screw of the compression means comprises said duct.
6. The aerator assembly according to claim 1 , wherein, said at least one aerator comprises a perforated membrane, which partially delimits a gas outlet chamber being in fluid communication with the inner space of the holder.
