Abstract

The invention discloses a device used for preparing metal powder of nanometer level, which includes an electrolysis bath and an electrical source. The electrolysis bath is comparted by two septa into one cathode chamber and two anode chambers. The cathode chamber is provided with a rotating cathode cylinder. The bottom of the cathode chamber assumes a funnel shape and is provided with a discharge port. The discharge port is communicated with a vacuum filter through a pipeline which is provided with an emptying valve. The lower end of the vacuum filter is communicated with a circulating pump through a pipeline which is provided with a tapping valve. The circulating pump is communicated with the two anode chambers respectively through two pipelines each of which is provided with a valve. The production process of the device is easy to be controlled and can achieve continuous preparation and separation.

Description

technical field [0001] The invention relates to a device for preparing nanoscale metal powder. Background technique [0002] Ultrasonic electrolysis is a new method for preparing nanometer metal powder. [0003] Chinese patent CN1676670A discloses a method for continuously preparing nanometer metal powder by organic medium electrolysis / ultrasonic wave. The electrolytic cell is divided into a cathode chamber and an anode chamber by a diaphragm. This patent does not disclose other structures of the electrolysis device. [0004] Chinese patent CN101007354A discloses a method for directly preparing ultra-fine copper powder from copper concentrate and an ultrasonic membrane electrolysis device used therein. The device includes a membrane electrolytic cell divided into an anode pool and a cathode pool by a diaphragm, an ultrasonic generator and a stirrer, the stirring rod of the stirrer is inserted into the anode pool, and a powder collector is arranged under the anode. [0005]...
