Title: (EN) Vertical powder production equipment of plasma rotating electrode and powder production process
(ZH) 一种等离子旋转电极立式制粉设备及制粉工艺
Abstract: front page image
(EN) The invention discloses vertical powder production equipment of a plasma rotating electrode. The equipment comprises a vertical powder production furnace body, an electrode rod inserted in the bottom of the vertical powder production furnace body, and a plasma gun arranged at the top of the vertical powder production furnace body; a gun head of the plasma gun is aligned to the end part of the electrode rod; multiple guide rods are vertically arranged at the bottom of the vertical powder production furnace body; the bottoms of the guide rods are fixedly connected with fixed stoppers; movable beams are slidingly mounted thereon; a rotating mechanism and a feeding mechanism are mounted on the movable beams; a movable sealing mechanism is arranged between the electrode rod and the bottom wall of the vertical powder production furnace body; and the vertical powder production furnace body is connected with a powder collecting cylinder, a vacuumizing system and an inert gas protecting system. In addition, the invention further discloses a process for preparing metal spherical powder by using the vertical powder production equipment of the plasma rotating electrode. The vertical powder production equipment of the plasma rotating electrode is simple in structure and convenient in use, improves the particle size and the particle size distribution of spherical metal powder, is small in particle size and high in sphericity of the generated spherical powder, greatly improves the quality of the metal powder, and can be popularized and applied.
(ZH) 本发明公开了一种等离子旋转电极立式制粉设备,包括立式制粉炉体、穿入立式制粉炉体底部的电极棒和设置在立式制粉炉体顶部的等离子枪,等离子枪的枪头正对着电极棒的端部,立式制粉炉体的底部竖直设置有多根导向杆,导向杆的底部固定连接有固定挡块,上滑动安装有动梁,动梁上安装有旋转机构和送进机构,电极棒与立式制粉炉体的底壁之间设置动密封机构,立式制粉炉体上连接有收粉筒、抽真空系统和惰性气体保护系统。另外,本发明还公开了利用等离子旋转电极立式制粉设备制备金属球形粉末的工艺。本发明结构简单,使用方便,提高球形金属粉末的粒度和粒度分布,产生的球形粉末粒径小,球形度高,极大地提高了金属粉末质量,可推广应用。
