MODULE AND FILTER FOR WATER PURIFICATION Russian patent published in 2002 - IPC

FIELD: devices for purification of water, mainly, potable one. SUBSTANCE: module for water purification based on siphon effect includes body having filtering chamber accommodating filter medium, means in body base for supply of water to be purified and ensuring water through filtering chamber from bottom upward, airtight cavity in module upper part for receiving of purified water passing from filtering chamber, and device for withdrawal of purified water in the form of downcast shaft whose inlet is communicated with airtight cavity, and outlet is located below means of water supply for purification. Downcast shaft is made with at least one device for regulation of water filtering and located in upper part of downcast shaft at height below airtight cavity of receiving of purified water sufficient for overcoming of surface tension forces for provision of water filtering in module and withdrawal of purified water with water level below module upper level. Device for regulation of water filtering is made in the form of jet nozzle with one linear size smaller than size of particles of filter medium on base of granulated and/or fibrous material. Downcast shaft may be made in the form of channel of variable or constant cross-section, or detachable and consisting at least of two members. Filter for water purification based on siphon effect has in combination a module of said design and container for water with upper section for purified water. Tightly secured inside said section in concave base by means of protruding of downcast shaft is filter module with concave base and lower section for purified water in the form of jar whose upper part accommodating section for water to be purified. Invention provides for purification of water by filtering through adsorption-bactericidal material under domestic conditions by self-flowing from bottom upward on basis of siphon effect. EFFECT: increased reliability of filtering process in time. 12 cl, 7 dwg
