DEVICE FOR DISPENSING POWDERS WITH SUBSEQUENT MIXING Russian patent published in 2019 - IPC C23C24/08 C23C24/10 B05B7/20 

FIELD: technological processes.

SUBSTANCE: invention relates to welding production, in particular, to devices for mixing with simultaneous batching of powders for plasma and gas-flame facing. Proposed device comprises housing composed of chamber with gas feed and discharge channels with two or more hoppers with powder feed tips arranged at top section. Powder feeding tips are made in the form of ejectors arranged in additional channels for supply of gas mixture to mixing chamber, at the inputs of additional and main channels there are feed regulators and gaseous mixture flow rate transducers.

EFFECT: possibility of two-channel supply of powder mixture depending on amount of supplied gas mixture for correct dosage of powders at mixing directly during fusing, uniformity of built-up layer, good adhesion between particles of powder and with base metal.
