AERATION DEVICE FOR CLOSED CONTAINERS, EXTRACTED WITHOUT PUMPING OF AERATED FLUID Russian patent published in 2020 - IPC C02F1/00 C02F3/02 

FIELD: treatment of water, industrial and household waste water or sewage sludge.

SUBSTANCE: invention relates to biological treatment of waste water, specifically to aeration device, extracted without pumping of aerated fluid. Aeration device includes vertical feed pipeline with engagement and sliding assemblies, rotary device, horizontal distributing pipelines, support trolley with engagement elements and guides, lifting chain or rope. Horizontal distributing pipeline of aeration element moves along lateral guides by means of support trolley with engagement elements and has connection by means of rotary device with vertical supply pipeline, which moves along central vertical guide by means of assemblies of engagement and sliding. Guides are rigidly fixed along one vertical wall and bottom inside aerated tank with provision of smooth turn at joint of vertical and horizontal lateral guides. At the same time vertical supply pipeline in upper part has locking device-tap with detachable connection on the side of outlet vertical pipeline of aeration element. On the air supply pipe from the air manifold there is a rotary joint for turning the disconnected shutoff device under the ceiling to release the opening of the head when removing the aerator by means of a chain or a cable and an external lifting mechanism.

EFFECT: technical result consists in simplification of maintenance and repair of aeration system without need to stop operation of structure, as well as increase in reliability.
