FOAM GENERATOR Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: foam generator has a dispersion chamber made in the shape of a frustum expanding on the move of the foam and a blind cylinder connected with the chamber walls by at least one helical partition and mounted along its axis. The filler is made of fibrous resilient material. The branch pipes for the air and the foaming agent converge in the sprayer mounted in the input to the dispersion chamber. There is a distributing foam conduit in the output of the dispersion chamber. The innovation relates to the devices for preparing the technical foam and can be used in the foam-concrete-mixing plants. EFFECT: ensured assigned multiplicity of foam and decreased dimensions without lowering the productive capacity. 2 dwg
