DEVICE FOR CIRCULATION TREATMENT OF WATER WELL Russian patent published in 2003 - IPC

FIELD: underground water intake. SUBSTANCE: invention relates to operation of underground water intakes, particularly, to devices for reconditioning of wells by reagent methods. Proposed device for circulation treatment of well for water contains water lifting tubing with set of disks secured on tubing at fixed distance from each other, carcass in form of perforated tube, gravel charge, outer case in form of ellipsoid of rotation whose smaller axis coincides with geometric axis of water lifting tubing. Surface of rotation is porous, with screw-like guides in contact with holes of perforated tube. Hydraulic coupling between screw-like guides and perforated tube is provided by means of flat horizontal flexible ring, flexible vertical pipeline coupled with pressure source, and ejector whose mixing chamber is connected with flexible vertical pipeline. Ejector is coupled through outlet section with gravel charge, and cover is secured over outer case. Said cover is made in form of curve to "witch of Agnesi" on inner surface of which curvilinear cycloidal conductors are provided. Pulsator is installed in ejector mixing chamber. Pulsate is made of curved bimetallic plates, not less than four in number. EFFECT: intensified regeneration of well, increased well output. 3 dwg
