Abstract
For the continuous mixing of fluid process materials or gases as they flow uninterrupted from a point of initial mixing to a discharge end and processed by means of intense vaporous cavitation, use is made of a resonant tube section having an entrance end and an exit end. The tube section is isolated from the rest of the supporting structure by means of resilient isolation mounts. A source of sinusoidal energy is connected to and excites the resonant tube section into one of its modes of natural frequency causing intense resonant sinusoidal acoustic energy to be developed and transmitted in spherical fashion from the inner resonant tube wall and throughout the flowing fluids. The energy thus released generates intense acoustical vaporous cavitation energy which breaks the surface tension and mixes the materials.

A mixer for the continuous mixing of fluids comprising a hollow main conduit for the continuous passage of fluids having an inflow port and an outflow port and being resilient throughout the length thereof between said ports, resilient supporting means having a supporting engagement with said conduit throughout at least a portion of its length, a plurality of supply conduits for respective fluids to be mixed, said supply conduits having discharge ends directed into said inflow port, a single source of sinusoidal energy having a predetermined mass and including a mounting member, said mounting member being subject to said sinusoidal energy, and being in direct communication with said hollow main conduit at a single location intermediate opposite longitudinal extremities of said resilient supporting means, said single source of sinusoidal energy having a line of action in perpendicular alignment with the longitudinal centerline of said main conduit, said source of sinusoidal energy having an attachment to the main conduit at an antinode and extending longitudinally for a distance less than the distance between adjacent nodes.
A mixer for the continuous mixing of fluids comprising a hollow conduit for the continuous passage of fluids having an inflow port and an outflow port, resilient supporting means having a supporting engagement with said conduit throughout at least a portion of its length, a plurality of supply conduits for respective fluids to be mixed, said conduits having discharge ends directed into said inflow port, a source of sinusoidal energy including a mounting member, said mounting member being subject to said sinusoidal energy, and being in direct communication with said hollow conduit at a location intermediate opposite longitudinal extremities of said resilient supporting means, said conduit comprising an elongated resonant tube and wherein there is a second tube of larger diameter than said first identified tube and coextensive and concentric therewith, said resilient supporting means comprising elastomeric pads respectively at opposite ends of the conduit isolating said tubes from each other.
