METHOD TO LIFT WATER AND DEVICE FOR ITS REALISATION Russian patent published in 2012 - IPC F04B47/00 

FIELD: mining.

SUBSTANCE: method to lift water and a device for its realisation may be applied in water supply from underground sources, and also when mining through wells and building wells, especially in rural localities for suburban farming and gardening. The method to lift water from wells by pulling excessive pressure to water surface in a well by weight of a water-receiving nozzle body with water-lifting pipes and whenever ballast is required. Water is taken in from the bottom part of the well with preliminary or simultaneous loosening of sand and silt deposits at the well bottom and stirring of these deposits. The device for method realisation comprises a water-receiving nozzle with elements of hydraulic sealing on the side surface of its body, water-lifting pipes. It is equipped with a mechanism of reciprocal movement of the nozzle with water-lifting pipes, the nozzle end is equipped with elements for loosening of sand and silt deposits at the well bottom, and water-lifting pipes on the day surface are equipped with a yoke and handles to ensure pipes rotation around the vertical axis.

EFFECT: method and device for its realisation make it possible to clean wells from accumulation of sand and silt in them in process of operation of these walls and thus prevent reduction of flow rate due to clogging.
