ELECTRIC ARC SIX-JET PLASMATRON Russian patent published in 2014 - IPC H05H1/26 

FIELD: electricity.

SUBSTANCE: design of the offered six-jet plasmatron includes plasma forming copper heads installed on dielectric boards, rigidly fixed to brackets with a possibility of movement along axes of heads perpendicular to tubular racks. Above them annularly the tubular chamber of argon feeding to the heads protecting electrodes from oxidation, and working gas distribution chamber are located. Above racks axially to the above mentioned chambers the chamber for supply of cooling water into sections of heads from the vertical channel of water supply and chamber for water dump into the channel, which are connected with the sections of heads with flexible hoses, are located. For water flow cooling a radiator is provisioned. The racks are located on the bench, between racks the branch pipe forming analysable gas stream or processed powder material is rigidly installed, and the cylinder providing the synchronism of change of angle of convergence of six heads by means of the system, comprising the board with installed mobile brackets, ensuring change of value of inter-electrode interval of plasma-forming heads.

EFFECT: possibility of complete monitoring of any gas flow during thermal processing of any powder materials of preset fractional composition using the plasma flow.
