FILTER OF DRIP IRRIGATION Russian patent published in 2003 - IPC

FIELD: agriculture; agricultural engineering industry. SUBSTANCE: the invention relates to agricultural engineering industry, in particular, to the drip irrigation systems. The filter includes a container and the inlet and outlet branch pipes located in the diametrically opposite butts of the container. The branch pipes are linked by a collector with the upper and lower distributing pipes horizontally mounted in the container's cavity. The filter is hydraulically linked with the system of drift-and-silt bearing waters supply and offtake of the pollution products and the purified water into the main pipeline of the drip irrigation system. The filter has a control system, a by-pass pipelines and hydrocyclones, hydraulically in parallel linked in the system of the drift-and-slit bearing waters supply and offtake of the pollution products, and the inlet branch-pipes at diametrically opposite butts of container and with its upper horizontally mounted perforated pipe. Each of the hydrocyclones has the mounted in its cavity a gauze filter made in the form of a truncated cone. The major basis of the gauze filter is directed to the side of the hydrocyclone purified water outlet. The small basis of the cone is oriented to the side of the drift-and-slit settling chamber. The chamber of settling is linked by a valve and a pipeline to the pollution products offtake system. EFFECT: the invention allows to increase productivity of the filter and to improve quality of purified irrigation water. 5 cl, 1 dwg
