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

FIELD: chemistry.

SUBSTANCE: water filter based on obtaining melt drinking water includes zones of water freezing, displacement of admixtures from ice front and concentration of admixtures in form of brine, transfer of water from solid state into liquid, placed successively in one longitudinal vessel 1. Ring freezing chamber 2, after which is drive device 4 of longitudinal travel of frozen water rod 3 mounted, is installed in freezing zone. In zone of displacement of admixtures in center of frozen rod 3 is placed dissociative device 6, after which ring heating element 11 is placed, is located in zone of admixture displacement on the centre of frozen rod 3. Drive device 4 is equipped with additional amplifiers of travel of frozen rod 3, made in form of drive screws 15, placed in longitudinal vessel 1 and passing through zones of water freezing, admixture displacement and water transfer from solid state into liquid one. Position of drive screws 15 relative to longitudinal vessel is provided by bearings of sliding 16, placed outside longitudinal vessel 1.

EFFECT: increased productivity and serviceability of water filter.
