FILTER OF THE DRIP IRRIGATION SYSTEM Russian patent published in 2003 - IPC

FIELD: agriculture; agricultural engineering industry. SUBSTANCE: the invention relates to agricultural engineering industry and may be used in agriculture, in particular in the water purification systems of the drip irrigations systems. The filter of the drip irrigation system contains high-pressure hydrocyclone, a sealed container with filtration material and the slit-type pipelines mounted there and the gauze filter. The filter is mounted in a network of the water supply from a pumping plant into the main pipeline. The filter is supplied with an additional high-pressure hydrocyclone and together with the basic filter is hydraulically in parallel linked with the pumping plant and the upper slit-type pipeline mounted in the sealed container above the filtration material. The gauze filter made of a fabric material is placed on the surface of the slit-type pipeline mounted under the filtration material. Ends of the slit-type pipeline by means of a pair of the three-stage valves are linked with the main pipe and the rundown pipes with an additional pair of the three-stage valves in the network of water delivery from the pumping plant into hydrocyclones. Control of the filter operation modes is exercised by turning the bits of the three-stage valves in a proper position. EFFECT: the invention allows to increase a filter capacity before water feeding to trickles. 1 dwg
