INSTALLATION FOR HYDRODYNAMIC PURIFICATION OF LIQUID MEDIA FROM MECHANICAL IMPURITIES Russian patent published in 2022 - IPC B01D29/44 B01D39/16 B01D29/11 

FIELD: waste treatment.

SUBSTANCE: invention relates to equipment for purifying liquids from mechanical impurities and can be used in various areas of the national economy where it is necessary to clean liquids from a large volume of contaminants. The installation includes a cylindrical housing 1, a nozzle 3 for the forced supply of purified liquid medium, a nozzle 11 for draining the purified medium, a hydrodynamic filter element 17 fixed in a horizontal partition 14 with the formation of an annular gap 25. In the horizontal partition 14, angular nozzle heads 16 are installed with the possibility of movement in vertical and horizontal planes. The filter element 17 is made of a polymer material in the form of a cylindrical shell with a sealed upper base 18, fixed to the horizontal partition 14. The lower movable base 19 of the filter element 17 is attached to a hollow cylindrical metal rod 20 with a micrometer thread on its outer surface. The rod 20 is placed with the possibility of moving inside the nozzle 11 for draining the purified medium and is fixed with a nut 22 with a micrometric thread. The filter element 17 is made with threaded slot channels 26 of variable increasing pitch along the length of its longitudinal generatrix and decreasing angle of inclination to the horizontal axis in the direction of the movable base 19. The pressure nozzle of the centrifugal pump 35 is connected by an additional hydraulic line through a tee with a shut-off valve 38 to the nozzle 3 for the forced supply of liquid medium.

EFFECT: simplification of the design with the expansion of technological capabilities while increasing the efficiency of cleaning liquid media due to the possibility of increasing or decreasing the slot channels during tension-compression of the filter element.
