NOZZLE FOR SPRAYING SURFACTANTS IN PLANTS FOR RESTORATION OF ASPHALT CONCRETE PAVEMENT

摘要

FIELD: construction.;SUBSTANCE: nozzle for spraying surfactants for a plant for restorating the asphalt concrete pavement, fixed on the distribution pipes of the plant, comprises a hollow cylindrical housing with a throttle orifice, connected to the union nut, to which the liquid flow divider is attached. The fluid flow divider consists of coaxially arranged perforated conical shells, the space between which is filled with a fine mesh screen. The apices of the conical surfaces of the shells are directed away from the throttle orifice. In the lower part of the divider, a cylindrical perforated segment is fastened, fixed on the perforated conical shells. In the cylindrical perforated segment, a flow swirl made in the form of a spring is arranged.;EFFECT: improving the quality of the regenerated asphalt-concrete pavement and increasing the device operation efficiency.;2 dwg, 2 tbl
