KOCHETOV'S CENTRIFUGAL ATOMISER WITH COUNTER SWIRLING FLOWS Russian patent published in 2015 - IPC B05B1/34 

FIELD: machine building.

SUBSTANCE: centrifugal atomiser with counter swirling flows contains a casing with vortex chambers and nozzle. The casing is made in form of the union with hole for liquid supply from main line and rigidly connected with it cylindrical coaxial sleeve with external thread. In the sleeve cone and cylindrical cavities are installed in series, they are coaxial with hole for liquid supply. Coaxially with casing in its bottom part a nozzle is connected, it is made in form of two-stage centrifugal cylindrical swirler connected with output cone chamber of the nozzle and separated from the hole for liquid supply by the perforate partition, secured at the end surface of the swirler casing. The partition looks towards the liquid supply, at that the first stage of the swirler is located in its top part, and contains cylindrical chamber with coaxially installed rod and secured on it helical plate. At that rod is secured in centre of the perforate partition. Second stage of the swirler is located coaxially with the first one and is made by ring cylindrical chamber connected is series with the cylindrical chamber of the swirler first stage, and has tangential inputs for liquid supply via the cylindrical ring cavity made by the casing of the swirler and cylindrical cavity of the sleeve. On the cone surface of the output cone chamber of the nozzle the screw thread is cut with direction of the flow swirling, opposite to direction of two-stage centrifugal cylindrical swirler.

EFFECT: increased efficiency of spraying due to increase of spray and to fine dispersion of sprayed liquid.
