An apparatus for mechanical spray treatment of materials has a container for preparing an abrasive suspension, the container having a stirring mechanism including a stirrer provided with at least one blade, and a sprayer for spraying the abrasive suspension connected to the container and a compressed gas supply device. The stirrer of the stirring mechanism has a comminuting cutter provided thereon in the bottom part of the container. The method for aerohydrodynamic abrasive cleaning of surfaces includes entraining the abrasive suspension flow in compressed gas to produce aerosol particles and directing the stream of aerosol particles from the sprayer nozzle to a surface. Moreover, after aerosol particles have been formed they are accelerated owing to the sprayer design within the sprayer before they are ejected from the nozzle. The method and device help improve the output, efficiency, and quality of cleaning by improving the uniformity of abrasive material grains used and imparting a high velocity to the suspension spray, expanding the area of effective cleaning, and distributing the aerosol particles therein in an optimal proportion.
An apparatus for aerohydrodynamic abrasive cleaning of surfaces comprising a container for preparing an abrasive suspension by a stirring mechanism including a stirrer having at least one blade, and a sprayer for spraying the abrasive suspension connected to said container and a compressed gas supply device, wherein the stirrer of the stirring mechanism has a comminuting cutter provided thereon in the bottom part of the container.
A sprayer for aerohydrodynamic abrasive cleaning of surfaces comprising a hollow body provided with a nozzle at the outlet thereof, a compressed gas flow channel and a cleaning suspension flow channel, both connected to the body interior, wherein the compressed air flow channel is connected to the cylindrical interior of the body at the side thereof opposite to the nozzle, the sprayer is provided with an atomizer in the form of a T pipe received in the body interior, the crosspiece of said T pipe extending along the body axis and the vertical leg thereof being connected to the cleaning suspension flow channel, the nozzle has a tapering part and a cylindrical part at the outlet thereof, and the outlet aperture of the atomizer is spaced from the inlet of the cylindrical part of the nozzle to provide a zone for accelerating cleaning suspension aerosol particles.
A method for aerohydrodynamic abrasive cleaning of surfaces by entraining the abrasive suspension flow in compressed gas to produce aerosol particles and directing the stream of aerosol particles from the sprayer nozzle at the surface, wherein the aerosol particles formed are accelerated within the sprayer before they are ejected from the nozzle.
