INSTALLATION FOR PRODUCING POWDERS OF METALS, ALLOYS AND CHEMICAL COMPOUNDS BY ELECTRIC EXPLOSION OF WIRE Russian patent published in 2005 - IPC

FIELD: production of powders by electric explosion of wire.

SUBSTANCE: installation includes reactor for electric explosion of wire with high-voltage and low-voltage electrodes that are connected to pulse current sources; mechanism for feeding wire to reactor; gas and powder circulation system; unit for separating gas and accumulating powder. According to invention gas and powder circulation system is in the form of tubular gas discharging pipes communicated by their one ends with reactor in front of inter-electrode gap and by their other ends - with unit for separating gas and accumulating powder. Said unit is in the form of successively connected through branch pipes expanders. Each expander is provided with powder accumulator at providing relation Si/Si+1 ≥ 1.43 where i = 1, 2…, Si - total surface area of effective cross section of tubular gas discharging pipes; S₂, S₃ - surface area of connection branch pipes.

EFFECT: enhanced quality of product due to lowered agglomeration of powder.
