DEVICE FOR PURIFICATION AND DISINFECTION OF WATER Russian patent published in 2023 - IPC C02F9/00 

FIELD: mechanical engineering.

SUBSTANCE: device for purification and disinfection of water contains a body equipped with a lid with ledges in the lower part, a cylinder-shaped filter element, the diameter of which is equal to the inner diameter of the body, an inlet pipe, a sump made in the form of a hollow hemisphere with the centre facing down, installed in the lid outlet, UV LEDs mounted on the inner surface of the cover, and a tube vertically mounted in the housing and connected to the inlet. A perforated sleeve is installed in the centre of the filter element. A casing is installed in the lower part of the perforated bushing, the lower part of which is made in the form of a hollow cylinder, and the upper part has a conical shape. A hole is made in the upper part of the casing, the diameter of which is equal to the diameter of the perforated sleeve. On the inner side surface of the lower part of the casing there is a removable cylindrical sleeve made of an elastic material and equipped with ribs installed along its generatrix. The inner side surface of the lower part of the casing is provided with locking protrusions in its upper part, and the removable sleeve is made with grooves in its upper base. The base of the casing is removable. Holes are made at the periphery of the casing base. Inside the casing, at the lower end of the tube, a perforated hollow cylinder is installed, the diameter of which is equal to the diameter of the tube. On the upper part of the perforated hollow cylinder there is a cone-shaped plate, directed upwards by the cone. Blades are installed on the underside of the dish. On the lower side of the casing, along its centre, a shaft is installed with the possibility of rotation together with the casing, passing through the centre of the sump.

EFFECT: improved quality of water purification and disinfection.
