Abstract:

An improved mixing device for mixing at least two of a plurality of pressurized liquids, the device consisting of hollow tubular member defined as having a longitudinal axis, one or two open ends and an interior wall member, one of the open ends having at least two cut-out portions generally symmetrically disposed about the axis, a segmental slot member generally radially disposed in the hollow tubular member between each of the cut-out portions for receiving a supporting projection in locking engagement therewith, and an envelope mounted on and extending about each of the cut-out portions for receiving and encompassing a conduit member terminating at and within each of the cut-out portions, each envelope being disposed, constructed and arranged for directing one of the plurality of pressurized liquids onto a proximate area of the interior wall means thereof. The wall is cleaned by turning off the fluid flow but the blades continue to be rotationally driven whereby the wall is wiped clean by the blades which push the residue out the tubular members.
