ROTATING DISK FILTER WITH A BACKWASHING SYSTEM INCLUDING A SUPPORTING ELEMENT OF A JET SUPPLY BRANCH PIPE Russian patent published in 2021 - IPC B01D33/21 B01D33/50 

FIELD: filters.

SUBSTANCE: invention is intended for water filtration. The rotating disk filter is comprised of a rotating water reception drum, a drive unit, a series of disk-shaped filtering elements fixed around the drum, a filtering medium located on opposite sides of the disk-shaped filtering element for filtering water, a backwashing system for backwashing of the filtering medium. The backwashing system includes a series of supply backwash pipes, a series of nozzle holders supported in a cantilevered manner at a distance from the supply pipes. Each nozzle holder comprises an elongated main pipe with an inner end part, multiple branched pipelines separated in space and extending outward from the main pipe and including end sections, nozzles located on the end sections of the branched pipelines, a connector located on the inner end part of the main pipe. Each connector is connected with a corresponding supply pipe and in an adjacent manner with the hole therein and is configured to support the associated nozzle holder in a cantilever manner at a distance from the supply pipe. Each connector additionally connects the inner end of the main pipe with a hole in the corresponding supply pipe, allowing the backwash flow to flow from the supply pipe through holes made therein and into the main pipe of the nozzle holder.

EFFECT: reducing the assembly time and reducing the possibility of leaks.
