ABSTRACT:
The invention is directed to an apparatus and a method for thoroughly mixing a suspension containing a fluid and solid matter constituents and spraying the thoroughly mixed suspension onto a surface. The apparatus includes a pressure and seal tight container enclosed on all sides for accommodating the suspension therein. The container has a top region and has a base region whereat the solid matter constituents tend to collect to form a sediment. A cylinder and a piston generate a charge of air under pressure which is conducted through a passage into the base region of the container to break up the sediment and thoroughly mix the solid matter constituents in the fluid as the air under pressure rises through the suspension to collect at the top region of the container where it imparts pressure to the suspension. A nozzle unit mounted on the container vents the container to permit the air under pressure to entrain the thoroughly mixed suspension to form a spray. With the invention, the suspension is always thoroughly mixed for each pumping operation and during the spraying operation so that a loss of function because of blockage of the spray system is prevented.
