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 has a body supplied with the inlet and outlet branch-pipes and filled with a sorbent as well as with a sorptive offtake network and hydrocyclones. The hydrocyclones are linked through the collectors with inlet and outlet branch-pipes receiving and deflecting connecting pipes of the filter body. There are a perforated distributing pipeline and the slit-type offtake-pipes mounted in the filter body cavity. The distributing pipeline in the body is mounted above the sorbent surface. The drainage water offtakes are mounted in a base part of the body. Each hydrocyclone has a gauze filter in its cavity and a sorptive collector located units lower part. The first hydrocyclone located in the filter hydraulic network is supplied with a manometer, mounted on the inlet pipeline. A manometer of the second hydrocyclone is mounted on the pipeline of the purified water feeding. The first collector has a manometer and a pair of valves. It is installed between the hydrocyclone and the inlet branch-pipes. The collector is in series through the valves linked with the upper perforated distributing pipeline and with the drainage water offtake located in the lower part of the body. The lower offtake branch-pipe of the body is linked to the second hydrocyclone through the supplied with the manometer and coincidence gates of the second collector provided with a monometer and valves. The second valve of the collector equally as the upper offtake branch-pipe of the body and the valves of the sorptive collectors is in series hydraulically linked with the sorptive offtake network. EFFECT: the invention allows to increase the filter capacity and quality of water-purifications. 1 dwg
