WATER PURIFIER Russian patent published in 2014 - IPC C02F1/22 

FIELD: chemistry.

SUBSTANCE: water purifier based on obtaining melt drinking water includes successively located in one longitudinal vessel 1 zone of water freezing, extrusion of admixtures from ice front and concentration of admixtures in form of brine, transition of water from solid state into liquid state. In zone of freezing installed is circular freezer 1, after which mounted is drive device of longitudinal displacement of frozen rod 3 of water. Disconnecting device 6, after which circular heating element 11 is placed, is located in the centre of frozen rod 3 in zone of extrusion of admixtures. To discharge admixtures in form of brine and melt water separate branch pipes 8, 12, located in the bottom part of longitudinal vessel 1, are installed. Drive device is equipped with additional amplifier of frozen rod 3 travel, made in form of endless belt 15, which passes in the centre of longitudinal vessel 1 through zone of water freezing, zone of extrusion of admixtures, zone of water transition from solid state into liquid and has motion drive. Position of endless belt 15 with respect to longitudinal vessel is provided by means of tension rollers 16, installed outside longitudinal vessel 1.

EFFECT: invention makes it possible to increase productivity and durability of water purifier.
