PLANT FOR PREPARING SALT SOLUTION FOR PURIFYING DRINKING WATER AT WATER INTAKES Russian patent published in 2017 - IPC C02F1/00 B01F3/00 

FIELD: machine engineering.

SUBSTANCE: plant comprises a rotating drum and a body. The drum is mounted from sections made of six, eight, ten, twelve, etc. even number of equilateral triangles connected to each other by two lateral sides. The sections are connected to each other by free third sides of triangles to form a screw drum, three, four, five, five, six and more broken right and left screw lines and provided with internal three, four, five, six and more screw grooves facing each other with the same pitch. There are three and more tension springs with flat section of turns mounted inside the drum and equipped with a device for changing the pitch of the turns by its stretching or compression. The drum is provided with a loading device in the form of a bushing, which inner surface is fixed at an angle of at α least three screw inserts of rectangular shape curved in width and length by known methods.

EFFECT: simplified manufacture, increased efficiency and expanded technological capabilities of the plant.
