Equipment for preparing metal nano powder by spiral wire feed counter-current electrical explosion method

Abstract

The invention relates to equipment for preparing metal nano powder by a spiral wire feed counter-current electrical explosion method, which comprises a host device I, a collection device II, a vacuum device III, an air conveying device IV, a water cooling device V and a wire feed mechanism VI, wherein the host device I is arranged above a bracket; the collection device II, the vacuum device III, the air conveying device IV and the water cooling device V are connected with a gate valve through a pipeline to form a closed loop; and the host device I is provided with the wire feed mechanism VI inside. The equipment has reasonable structure, safety, reliability, simple and convenient operation, wide applicable range, high yield, high raw material and energy utilization rate, environmental protection, no pollution, and even grain diameter of powder, and not only can produce pure metal nano powder, but also can produce alloy nano powder. When pure metal or alloy can be pulled into wire materials, the pure metal or alloy can be used for the industrialized production of various pure metal or alloy nano powders by the equipment, and can be used for preparing metal or alloy nano powder in a lab through proper simplification.
