Abstract:
A mobile apparatus for the production of water-based liquid paints from pulverulent constituents and water, the apparatus comprising:a) a traveling frame;b) a mixing container supported on the frame, the mixing container comprising a cylindrical wall and a ring conduit extending circumferentially about an upper edge of the cylindrical wall of the mixing container, wherein the ring conduit has holes on its underside;c) a mixing unit for mixing the pulverulent constituents and water, the mixing unit being supported on the frame, the mixing unit comprising a dissolver driven by a mixing motor, the mixing unit being capable of being lowered into the mixing container via a spring;d) a metering unit for metering the pulverulent constituents into the mixing container, the metering unit comprising a metering container containing a conveying element for apportioning the pulverulent material into the mixing container, the metering unit further comprising a filling funnel and a metering motor for driving the conveying element; ande) a switching unit with control elements for controlling the metering and the mixing;wherein the dissolver comprises a shaft and a dissolver disc, the ratio d/D of the diameter d of the dissolver disc to the diameter D of the mixing container being about 0.3 to 0.5, and the shaft being dimensioned in such a way that, during the mixing operation, the dissolver disc can be lowered to a distance h from the bottom of the mixing container of about 0.3 d to 0.7 d, d being the diameter of the dissolver disc.
