Abstract

The invention discloses a method for preparing copper or nickel powder and an electrolysis device based on the same, so as to achieve continuous large-scale production. The method comprises the steps of: preparing electrolyte; clearing metal particles or turning scraps to be powdered to obtain a metal raw material; putting the metal raw material as a sacrificial anode into an electrolysis basket for electrolysis; continuously sending a suspension solution of the metal powder and the electrolyte out to filter and separate the metal powder; cleaning the filtered metal powder with deionized water; vacuum drying the metal powder; mechanically grinding the dried metal powder; and examining a finished product. The electrolysis device comprises an electrolysis tank, a cathode assembly plate, a conductive spindle, a ceramic bearing, a collector, an insulating coupling, a speed reduction motor, the anode basket, a bracket, a scraping brush, a separation tank, an acid-resistant pump and an overhead tank. The device has a compact structure, and the effective cathode area is enlarged by more than five times compared with the roller type electrolysis tank with the equal capacity, so that the working efficiency is greatly improved, and the labor intensity is reduced.

Description

technical field

[0001] The invention relates to a method for preparing metal powder by electrolysis and a device thereof, in particular to a method for preparing copper powder or nickel powder and an electrolysis device thereof. Background technique

[0002] As an emerging material, fine metal powder has attracted widespread attention and produced many preparation methods. Each method has obvious advantages and disadvantages. Judging from the current situation, the electrolysis method is one of the most promising methods to realize industrialization. The metal powder prepared by the electrolytic method has high purity, good compaction performance, and easy control of particle size. It can obtain fine metal powder that is difficult to prepare by other methods, and is more suitable for preparing metal powder with high electronegativity.

[0003] In conventional electrolytic powder production, it is necessary to periodically scrape the powder, which not only reduces the produc...
