"MIONS" FILTER FOR PURIFICATION OF POTABLE WATER Russian patent published in 2004 - IPC

FIELD: sanitary engineering; purification of potable water.

SUBSTANCE: the invention is intended for purification of potable water and is dealt with the field of sanitation equipment, in particular, with filters for purification of potable water and may can be used in other fields of engineering. The body is made in the form of two conjugated parts, the upper part of which has form of a cylinder, the lower part - the form of a truncated cone with a taper bottom and an axial hole. On the surface of the conical part of the body there is a protrusion, under which a gasket is located. On the surface of the conical part of the body there are vertical stiffening ribs. Along the axis of the body a separating cylinder with holes is installed. Inside the cylinder on its taper bottom a flat-bottomed filter element is installed, thickness of the bottom of which exceeds thickness of the wall, and the internal surface of the bottom is located at the level of the side holes of the separating cylinder. Between the external surface of the bottom and the internal surface of the separating cylinder there is a space sealed by a centering ring. The filter body is filled in with a granular material of different natural minerals, which form stages of purification and are located along the axis of the body and conjugated among each other through a separating gasket. On an external surface of a mineral there is a separating gasket, on which a lattice is installed. The volume of a material of the first stage exceeds the volume of the consequent stages. A rigid fixing of the elements located inside the body is made with the help of a nut having a hole. In the lower part of the nut there is a deepening, in which the gasket with a hole is placed. The separating cylinder side holes are shut with a porous material and the external surface of the filtering element is protected with the help of the porous material. The technical result is improvement of quality of water purification, increased service life of the filtering element and the filter and also decreased cost of the purified water and expansion of operation of the filter.

EFFECT: the invention ensures improvement of quality of water purification, increased service life of the filtering element and the filter, decreased cost of the purified water.
