INSTALLATION TO TREAT WATER MAINLY FOR DRIP IRRIGATION SYSTEMS Russian patent published in 2011 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural melioration and may be used to prepare water supplied to drip irrigation systems. Installation for water treatment comprises hydraulic cyclone, input and output pipelines with gate valves, chamber of treatment wastes collection with quick-detachable cover to manually remove wastes at one end wall and ball or plug valve for hydraulic cleaning of chamber - at the other one. Pipe filter is installed into inner part of hydraulic cyclone. Pipe filter represents a tubular item, in which perforated bearing frame is installed inside fibrous porous pipe with air gap between them. Lower end of pipe filter is plugged. Corrosion-resistant nozzle with flange is mounted at upper end on thread. Pipe filter is flanged to output nozzle of hydraulic cyclone and irrigation system by bolt joint. Input and output pipelines upstream gate valves are connected to each other by pipeline with gate valve. Such arrangement makes it possible to periodically change mode of operation. In one mode irrigation water is filtered by hydraulic cyclone and pipe filter; in other one - pipe filter and chamber of treatment wastes collection are washed with a return water flow into discharge system.

EFFECT: invention provides for improved technological and operational reliability, service life of drop lines and reduced labour inputs.
