Aeration and oxygenation equipment, in particular for fishing vats

摘要

Aeration and oxygenation equipment, especially for fishing vats (2), brings the possibility of aeration and oxygenation of water in the fishing vat (2) without the need for heavy weights and any restrictions on fishing. A special thin-walled aeration insert (1) with oxygenation is placed in the fishing vat (2), which is not self-supporting, but copies the walls (12) and bottom (11) of the fishing vat (2). Below the bottom (13) of the aeration insert (1) with oxygenation, two distribution aeration rings (3, 3´) and one distribution oxygenation ring (4) are located in the central part. The bottom (13) of the aeration insert (1) with oxygenation is perforated above the distribution aeration rings (3, 3´) and the distribution oxygenation ring (4) perforated by aeration holes (16) and oxygenation holes (17), through which air and oxygen bubbles escape into space of the fishing vat (2). The compressed air supply (5) and the compressed oxygen supply (6) to the aeration distribution rings (3, 3´) and to the oxygen distribution ring (4) are led under separate pipes under the bottom (13) of the aeration insert (1).
