CARTRIDGE FOR WATER CLEANER WITH NATURAL WATER FILTRATION Russian patent published in 2013 - IPC B01D27/08 B01D35/30 

FIELD: process engineering.

SUBSTANCE: this invention relates to cartridge for water cleaner with natural water filtration. Water cleaner cartridge comprises upper filtration cylinder 10, at least one lower filtration cylinder 20, bottom filtration cylinder 30 and raw water feed channel 40. Upper filtration cylinder 10 comprises feed tube 12 arranged in cylinder central part and multiple through holes made at its bottom. Besides, said upper cylinder comprises at least one guide ledge 50 made at its inner surface generator to direct raw water to lower cylinder inner central part. Upper filtration cylinder 20 comprises feed tube 22 arranged in cylinder central part and multiple through holes 21 made at its bottom. Besides, said lower cylinder 20 comprises at least one guide ledge 50 made at its inner surface generator to direct raw water to lower cylinder inner central part. Upper cylinder is arranged separately above upper cylinder 10 and above bottom cylinder 30. Vertical raw water feed channel is arranged at the assembly of tubes 12, 22 of said upper and lower cylinders to allow raw water filtration and release after filtration by forcing it into every cylinder and directing its flow upward.

EFFECT: maximum efficient filtration time and contact between raw water and filtration materials, higher efficiency of filtration.
