DEVICE FOR FOAMING OF SUSPENSIONS

摘要

FIELD: mining; may be used in foaming of suspensions in fighting of underground fires. SUBSTANCE: device has ejector, sleeve with combined channel, dispenser and mixing chamber. In ejector, suspension is separated into two parts. Main flow runs through sleeve and pulverized by dispenser. Additional flow runs through circular slot deflected by conical baffle onto foam-generating grid and runs down. Inert gas passes in hollow of gas jacket to form high-expansion foam pulp. Main flow is mixed with foam pulp. Formed in mixing chamber is foamed suspension. EFFECT: higher efficiency of preparation of suspensions on short holes due to intensification of foaming process. 1 dwg
